We're starting to stock a lot of chips that can do digital I2S out, which makes for great-quality audio playback. That's great when you have enough processing power to decode WAVs or MP3s in real-time. However, we could really use some better DACs in the shop. We like the UDA1334A (https://www.adafruit.com/product/3678), but that's technically discontinued - it's great because it doesn't require an MCLK that some boards like the Raspberry Pi don't have and doesn't need I2C configuration either. The PCM510x is a good family, too; it ranges from the inexpensive PCM5100 (https://www.digikey.com/short/z50cnp0h) to the PCM5102 (https://www.digikey.com/short/80z2nh3h) which has high quality output at a higher cost. This breakout could use any of the family chips & gives you all the GPIO needed with a 3.5mm headphone jack for line-level output. We're testing it out with some cool tunes from the adafruit soundcloud, check it out!

This week's EYE ON NPI is neither-here-nor-there - it's STMicroelectronics' ST25R200 NFC/HF RFID Reader IC (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/st25r200-nfc-hf-rfid-reader-ic) a simple but powerful NFC/RFID reader and writer chip that will let you add a contactless interface to your next design. Thanks to the high power RF stage and dual antenna support, you can avoid the frustration of "where do I tap??" by giving you plenty of surface area for successful transactions.We're big fans of intuitive RFID/NFC interfaces using tags, they come in all sorts of sizes and shapes (https://www.adafruit.com/product/365) from standard business cards to microtags that can fit in a manicure (https://www.adafruit.com/product/2800). They don't require a battery, and can store up to a few KB of data, including encrypted/secured data sections so as to make the tag 'trustworthy'. They're often used for small-money transactions like copy shops, laundromats and public transport, where speed is important and we can store value on the card. Or for identification like access cards. With proper design, they'll work up to 4 inches away from a reader, don't suffer from corrosion or contact wear or affected by water/humidity.Reading and writing RFID/NFC tags, which use 13.56MHz as a carrier frequency, requires a proper chip that can handle the requirements of blasting enough RF signal to 'power' the tag, then transmit a command and receive the response before the quiescent power runs out. If you have a big antenna, this isn't too hard - but the real challenge is to manage it with a small antenna. That's the nice thing about the ST25R200 (https://www.digikey.com/short/5ttf9ptj) - it has powerful output drivers so even mini wearable-sized antennas work well. You can configure the outputs to be one differential or two single-ended antenna coils. If you want to design your PCB antenna, we recommend ST's website for NFC inductance calculations (https://eds.st.com/antenna/#/) it will let you determine the inductance based on width, height, copper thickness and trace width so you get maximum power transfer.The ST25R200's connection to the controller is over standard 4-pin SPI, so you can use any microcontroller or microcomputer with 4 pins available. An IRQ line is also handy to 'wake on card detect'. Other than that, the interface is fairly low level: registers are used to configure the RF section and encoding but otherwise, data is transmitted or received via two FIFO buffers. This makes the chip easy to adapt to the various sub-protocols and standards (https://nfc-forum.org/build/specifications) designed by competing RFID companies: ISFO14443A/NFC-A, ISO14443B/NFC-B, ISO15693/NFC-V, NFC Forum T1T, T2T, T4T, and T5T tag types, and proprietary protocols, such as Kovio, CTS, and B’. In order to make your life easier when it comes to implementation, ST has released RFAL an RF/NFC abstraction layer (https://www.st.com/en/embedded-software/stsw-st25rfal004.html) that is written in pure C so that it can be ported to any platform or compiler.To get started quickly we recommend the STEVAL-25R200SA evaluation board (https://www.digikey.com/en/products/detail/stmicroelectronics/STEVAL-25R200SA/25701817) which comes with a USB debug STLink interface, SMTable module, 4 pluggable antenna options including one flex PCB printed antenna, and two micro-tags for testing. If you want to integrate RFID/NFC 'touchless' support to your next design, the ST ST25R200 NFC/HF RFID Reader IC (https://www.digikey.com/short/5ttf9ptj) is small, inexpensive, and fast to get started with minimal external components, and ready-to-go drivers. And best of all the chips are in stock right now at DigiKey for immediate shipment. Order the ST25R200 (https://www.digikey.com/short/5ttf9ptj) and an eval board today and you can tap your way to contactless communication by tomorrow afternoon!

This week on EYE ON NPI we're eatin' our Wheaties (https://www.youtube.com/watch?v=QvyInWTLM8s) - it's the Analog Devices MAX96714 Single GMSL2/GMSL1 to CSI-2 Deserializer (https://www.digikey.com/en/products/base-product/analog-devices-inc-maxim-integrated/175/MAX96714/737256) a way to send high resolution digital video over a co-ax wire without losing quality. These advanced serial-deserial sets - we'll call them SerDes for short - let you minimize cabling, for reduced weight and complexity when passing high speed video from cameras or to displays over single flexible RG coax.It's easier than ever these days to add high quality video or camera sensing to your products: boards like the Raspberry Pi can do dual 4K HDMI and up to two DSI / CSI ports on the Compute Modules (https://www.digikey.com/en/products/filter/single-board-computers-sbcs/933?s=N4IgTCBcDaIMYHsC2AHArgFwKYAIkIBM0AbLEAXQF8g) but the cables that they come with tend to be short, maxing out at 500mm long. (https://www.digikey.com/en/products/detail/raspberry-pi/SC1130/21658263) That's because the MIPI protocol used for data transfer is designed for ultra high speeds over low cost flex PCBs, from say a laptop motherboard to the laptop monitor or webcam. Now, we do sell looooong cables (https://www.adafruit.com/product/2144) that are 2 meters long but with the caveat that they are well outside the expected spec. They do work! But we wouldn't put it in a product that goes to customers.So what do you do if you have a car, where the seats and dashboard have monitors but the main processor is probably in the back of the car, far from the hot engine? That's where Analog Devices got inspired from the Cable TV of our youth (https://en.wikipedia.org/wiki/Cable_television) that would let kids of the 90's watch dozens of channels using...only one cable! The cable, in this case, is a coaxial cable: one copper wire surrounded by a plastic dielectric, then a braided metal ground return. Coax cables are flexible but rugged, and DigiKey stocks thousands of different types (https://www.digikey.com/en/products/filter/coaxial-cables-rf/475) by the foot or reel. So they make an excellent physical transport layer for video in aggressive environments because they are shielded yet flexible.With GMSL you need two chips: a serializer like the MAX96717 (https://www.digikey.com/short/3pcv09pn) and a de-serializer like the MAX96714 (https://www.digikey.com/short/3jqw8tj8). Between the two, connect said coax, then configure both sides for the data format you want and boom, you have a transparent video link! The serializer will take the digital data, then turn it into a serialized-packetized-data-packet on a single wire. That thin wire can fit into spaces that would normally be a challenge such as cars / aerospace where weight is at a premium, robotics where the shielding will protect the signal integrity, and medical where high rez cameras have to fit in tiny spaces. GMSL even supports 'power over coax' where a DC signal can be used as a carrier for the high frequency data - so you really can have one thin cable for everything.Depending on which generation of GMSL you choose, you will get either 3 Gbps or 6. A small portion of that is 'upstream' communication, thats used for IRQs, video/camera control and extra I2C or GPIO. If you need stereo or quad camera/video , you can use a quad deserializer: you will still get 4 coax cables in but it'll be smaller and perhaps better synchronized than having four separate deserializers.To get started, we recommend picking up the MAX96714-BAK-EVK eval board (https://www.digikey.com/short/nh82vrbc), which is not inexpensive but does have everything you need to get started with the MAX96714 (https://www.digikey.com/short/3jqw8tj8). Note you'll also need the serializer! One thing that's nice is that if you want to get set up with a Raspberry Pi to start, you can order the Pi Cam Eval board (https://wiki.analog.com/resources/eval/user-guides/ad-gmslcamrpi-adp) which is an adapter for the eval to use off-the-shelf Pi camera modules, pick up at DigiKey (https://www.digikey.com/en/products/detail/analog-devices-inc/AD-GMSLCAMRPI-ADP/21678785). Then to set up the configuration you can use the Linux driver to have automatic setup (https://github.com/torvalds/linux/blob/master/drivers/media/i2c/max96714.c) without a separate configuration program.If you'd like to try out GSML for your next long-distance video product, you can pick up the Analog Devices MAX96714 Single GMSL2/GMSL1 to CSI-2 Deserializer (https://www.digikey.com/en/products/base-product/analog-devices-inc-maxim-integrated/175/MAX96714/737256) today from DigiKey because it's in stock for immediate shipment! Book now and you can be zipping along MIPI CSI data at 6Gbps by tomorrow afternoon.

We'd like high-quality I2S digital audio generation for our Fruit Jam board, and both 16-ohm headphone/line level out and a mono 8-ohm speaker driver.Ideally, we wouldn't need two or three chips to achieve this: the DAC would have headphone drivers and a class D speaker driver. We'll need I2C control, 3.3V logic, and up to 5V for speaker power. When you need a very specific setup for audio converters, sometimes it's easiest to go to the semiconductor website and search for the exact setup. (https://www.ti.com/audio-ic/converters/dac/overview.html) .Then you can book your order from DigiKey.See the chosen part on DigiKey: https://www.digikey.com/short/hjw02vdt-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.comLIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/

This week's EYE ON NPI is a Texas-two-steppin' motion controller that takes your 2-axis motion control to the next level: it's ADI/Maxim/Trinamic's TMC5272 Dual-Axis Stepper Motor Controller and Driver IC. We've been checking out many of Trinamic's great stepper motor driver chips lately and this one is the latest generation, with 2 drivers, plus motion control, for advanced usage even on boards that don't need real-time GPIO toggling for steps. Trinamic is definitely not a group that 'rests on their laurels': every year they are coming out with even more improvements to their awesome stepper motor drivers. This chip has 250 pages of datasheet and each page details yet another improvement or setting that will make your mechatronics fast, silent, and efficient.What sets the TMC5272 (https://www.digikey.com/short/0mq250r7) apart? Well, the first big thing is you get double the fun with two full stepper drivers for X and Y axis support. The voltage range is 2-20V, so good for low to medium voltage motors. The tradeoff is you can only get 1.5A max peak current, 1.1A sine wave, but for most users that don't have massive steppers that is perfectly fine. There's also a lot more 'smarts' in this stepper than the ones even from a couple years ago: 8-point motion control, no-loss/no-sense-resistor current management, 2D trajectory management over two axes, encoder or reference switch inputs, sensorless standstill motion detection. Of course all the fixin's you expect from the previous generations are there: silent stepping, UART and SPI and step/dir interface, stallguard, 1 to 256 microstepping, and diagnostic outputBut, it's in a 3x3mm WLCSP package: this means you'll need at least a 4 layer board and plugged vias. It also means heat dissipation might be more challenging than the drivers with the big ground pads. However, a nice tradeoff is that there is internal 'lossless' current sensing, so no chunky resistors are required. The upside of a WLCSP is that we have lots more pins for tons of interfaces. Each driver can run one bipolar stepper motor, and has multiple interfaces for control. As usual there's the STEP/DIR interface. This is great for usage with older designs that expect to toggle GPIO on each step. However, the S/D pins are shared with some of the cool sensors/encoders/switches. Plus all the really cool things the chip can do are too complex to adjust with just a few GPIO, so to really get the most use you'll need to use one of the packetized interfaces: UART or SPI. UART is great if you happen to only have USB for your computer: you can always just use a USB-serial converter, and the controller can be daisy-chained for multiple drivers per UART. If you have extra GPIO and/or a dedicated SPI port, we would recommend that since it's much faster and you can easily add more chips with one chip-select per.Some of the cool things you can do via the interface include a 8-point ramp controller: instead of stepping each motor and dynamically adjusting the micro-steps for speed/precision, the TMC5272 can do it all on its own. It can also handle knowing 'where' it is on an axis bar, by using the built in homing support. Homing can be done either by using the sensorless 'StallGuard' (https://www.analog.com/en/lp/001/building-better-stepper-motor-system.html) or with reference switches. You can wire the switches directly to the TMC5272 - good if you want to have slow motion homing since you don't have to whack into the end of the axis - and then let the chip manage where it is. Then you can tell it you want to move and when you want to get there, and the TMC will take care of the rest. For ultra-accurate motion control, you can connect an external optical or magnetic encoder to the motor shaft that will tell you exactly when a step has occurred. There's also a neat back-EMF sensor that can tell when the motor has moved while 'disabled' - good to know when you will need to do another homing step after re-enabling the motor.There's also an TMC5272-EVAL-KIT eval board that you can plug-n-play for instant stepper motor usage (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/TMC5272-EVAL-KIT/22107596), it works instantly with the TMCL IDE for trying out the various programmable settings (https://www.analog.com/en/resources/evaluation-hardware-and-software/motor-motion-control-software/tmcl-ide.html) and turn the motor via the TMCL IDE which sends UART/SPI commands over their USB driver board, so it's perfect for verifying the performance with your desired motors. If you want double the pleasure, double the fun of double-motor driving, you can pick up the ADI/Maxim/Trinamic's TMC5272 Dual-Axis Stepper Motor Controller and Driver IC (https://www.digikey.com/short/0mq250r7) from DigiKey today - it's in stock & ready to ship immediately! Place your order now & by tomorrow morning you can be step-step-stepping to the most advanced 2-axis motor controller design you've ever seen.

Build a countdown clock to help teach toddlers how to visualize time.Guide: https://learn.adafruit.com/toddler-timerThis project uses NeoPixel LEDs to represent blocks of time that can be setup to countdown any number of minutes.It features an OLED display to show the time remaining and a rotary encoder to set up the intervals and to start and stop the countdown.You can customize the blocks of time in the code and easily cycle between them with the rotary encoder.We think it's a unique way to show the passage of time with NeoPixel LEDs.This uses the Adafruit QT PY RP2040 dev board to drive the NeoPixels and the rotary encoder.CircuitPython makes it easy to change up the code so you can make adjustments or adapt to your roll your own countdown timer.You can customize the code to have different blocks of time or change the colors of the NeoPixel LEDs.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitShop for parts to build your own DIY projects http://adafru.it/3dprinting3D Printing Projects Playlist:https://www.youtube.com/playlist?list=PLjF7R1fz_OOWD2dJNRIN46uhMCWvNOlbG3D Hangout Show Playlist:https://www.youtube.com/playlist?list=PLjF7R1fz_OOVgpmWevin2slopw_A3-A8YLayer by Layer CAD Tutorials Playlist:https://www.youtube.com/playlist?list=PLjF7R1fz_OOVsMp6nKnpjsXSQ45nxfORbTimelapse Tuesday Playlist:https://www.youtube.com/playlist?list=PLjF7R1fz_OOVagy3CktXsAAs4b153xpp_Connect with Noe and Pedro on Social Media:Noe's Twitter / Instagram: @eckenPedro's Twitter / Instagram: @videopixil-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.com/?utm_source=youtube&utm_medium=videodescrip&utm_campaign=3dprintingSubscribe to Adafruit on YouTube: http://adafru.it/subscribeAdafruit Monthly Deals & FREE Specialshttps://www.adafruit.com/free?utm_source=youtube&utm_medium=videodescrip&utm_campaign=3dprintingJoin our weekly Show & Tell on G+ Hangouts On Air: http://adafru.it/showtellWatch our latest project videos: http://adafru.it/latest?utm_source=youtube&utm_medium=videodescrip&utm_campaign=3dprinting3DThursday Posts: https://blog.adafruit.com/category/3d-printing?utm_source=youtube&utm_medium=videodescrip&utm_campaign=3dprintingNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/?utm_source=youtube&utm_medium=videodescrip&utm_campaign=3dprinting-----------------------------------------
Folks may be familiar with our HalloWing M4 (https://www.adafruit.com/product/4300) fancy eyeballs demo code - it's very dependent on the wired-up hardware. But of course, with our new round displays (https://www.adafruit.com/product/6178), we wanted to try wiring one up to see how it looks. That ended up being 2 days of hacking, but at least it's done now - we've refactored the code to support any SAMD51 board and any SPITFT display. It's not ready for publication yet; We juuuuuust got this working like 3 minutes ago... We want to abstract out the SAMD51-dependant parts so it could be run on chips like the ESP32 or RP2350 (https://www.adafruit.com/product/6055)!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

Coming soon!We were catching up on a recent Hackaday hackchat with Eben Upton (https://hackaday.io/event/202122-raspberry-pi-hack-chat-with-eben-upton) and learned some fun facts: such as the DVI hack for the RP2040 was inspired by a device called the IchigoJam (https://www.hackster.io/news/ichigojam-combines-strawberry-and-raspberry-to-deliver-a-raspberry-pi-pico-powered-educational-micro-66aa5d2f6eec). We remember reading about this back when it was an LPC1114, now it uses an RP2040. Well, we're wrapping up the Metro RP2350 (https://www.adafruit.com/product/6003), and lately, we've been joking around that with DVI output and USB Host support via bit-banged PIO, you could sorta build a little stand-alone computer. Well, one pear-green-tea-fueled-afternoon later we tried our hand at designing a 'credit card sized' computer - that's 3.375" x 2.125", about the same size as a business card (https://hackaday.com/2024/05/07/the-2024-business-card-challenge-starts-now/) and turns out there's even a standard named for it: ISO/IEC 7810 ID-1 (https://www.iso.org/standard/70483.html).Anyhow, with the extra pins of the QFN-80 RP2350B, we're able to jam a ridonkulous amount of hardware into this shape: RP2350B dual 150MHz Cortex M33 w/ PicoProbe debug port, 16 MB Flash + 8 MB PSRAM, USB type C for bootloading/USB client, Micro SD card with SPI or SDIO, DVI output on the HSTX port, I2S stereo headphone + mono speaker via the TLV320DAC3100 (https://www.digikey.com/en/products/detail/texas-instruments/tlv320dac3100irhbt/2353656), 2-port USB type A hub for both keyboard and mouse or game controllers, chunky on-off switch, Stemma QT I2C + Stemma classic JST 3-pin, EYESPI for TFT displays, 5x NeoPixels, 3x tactile switches, and a 16-pin socket header with 10 A/D GPIO + 5V/3V/GND power pins. The PSRAM will help when we want to do things like run emulations that we need to store in fast RAM access, and it will also let us use the main SRAM as the DVI video buffer.When we get the PCBs back and assembled, what should we try running on this hardware? We're pretty sure it can run DOOM. Should that be first? :) We also need a name. Right now, we're just calling it Fruit Jam since it's inspired by the IchigoJam project.
While debugging a non-working bumper car toy for BabyAda, we determined that the vendor, for some reason, provided a 24V DC power adapter when the battery is 12V and should be charged only up to 15V max! Uh-oh, it's time to fix it up. Let's head over to DigiKey to get a new 12V lead-acid battery that is the same size and shape so we can swap it in and recycle the old one.See the chosen part on DigiKey https://www.digikey.com/short/hhbnn97m-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.comLIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/
BabyAda's bumper car toy stopped working after overnight charging - turns out 24V charger + 12V battery = problems. Quick fix: replaced battery with correct one from DigiKey. Pro tip -Always check voltage compatibility!

This week's EYE ON NPI is as ethereal as it is magical: it's Bel Fuse's 1xN port MagJack and specialty ICMs (https://www.digikey.com/en/product-highlight/b/bel-fuse/1xn-port-magjack-and-specialty-icms). These are specially made Ethernet and Ethernet-USB combo jacks that have magnetic transformers inside to make integration with your Ethernet PHY (https://en.wikipedia.org/wiki/Ethernet_physical_layer) in order to communicate on the network. MagJacks make designs smaller, and less noisy - they're a great way to simplify your next Ethernet design and get it to market faster!Wireless this, 5G that - what we sometimes need are WIRES! Wired networking is much reliable than wireless, and can go far distances with no loss of signal strength. Particularly as you can also put power over the same wires for nodes that need no other cabling, Ethernet is a reliable networking standard - don't discount it just because of its age! One nice benefit of it is you don't have to do SSID/password setup, it's truly plug and play.Three things are required to add Ethernet. First is a microcontroller or microcomputer that has built in Ethernet Medium Access Control (https://en.wikipedia.org/wiki/Medium_access_control), the low level packet forming technology. Some chips have this built in, such as the ESP32 (https://www.digikey.com/short/dz5pv22m) - or you can use a companion chip like the WIZ5xxx series (https://www.digikey.com/en/supplier-centers/wiznet) that can be controlled over SPI. Then, to get onto a network, you'll want the ubiquitous mechanical RJ-45 connector (https://www.digikey.com/short/t28834zr) that will lead to Cat-5 or Cat-6 cable (https://www.digikey.com/short/pnjh3t8d). In between, the signal levels need to be isolated and converted to the +-2.5V differential signal. To do that we need what is colloquially referred to as the 'magnetics': a cluster of transformers and chokes that will make the signal differential, isolate the PHY from the outside world and also reduce the risk of outside spikes and shocks. Both the Wiznet and ESP32 datasheets, for example, have example wiring to help you identify the right configuration. Note that not all chips have the same magnetics impedances / configurations: it depends on the output signal and impedance. Second, this is separate than PoE magnetics (https://www.adafruit.com/product/3847) which are separate from the data transfer. If you don't care about optimizing board size and complexity, you can always use external magnetics with a plain jack. Bel has a full selection of dozens of magnetics for any configuration you may need (https://www.belfuse.com/product-detail/icm-s-discrete-lan-magnetics). For example the Seeed Ethernet shield (https://www.digikey.com/short/70cvntbm) uses this technique because the PCBA is so big they have space to spare. However, when you want to keep your board compact, you can upgrade your design to use one of Bel Fuse's 1xN port MagJacks. (https://www.digikey.com/en/product-highlight/b/bel-fuse/1xn-port-magjack-and-specialty-icms)MagJacks provide two big benefits (https://www.digikey.com/en/product-highlight/b/bel-fuse/1xn-port-magjack-and-specialty-icms): one they're smaller than separate magnetics/jacks and second, the magnetics get enclosed in the metal shell of the jack which provides some EMI shielding. For example, we used a combo-jack on the Ethernet Featherwing (https://www.digikey.com/short/9w49r80j) to keep the design single-sided. Which is why we were excited to see the Bel Fuse MagJacks pop up on https://www.digikey.com/new - they're a trusted component we've used before.For this week's EYE ON NPI, DigiKey is highlighting a selection of the new Bel Fuse MagJacks, with dozens of options available (https://www.digikey.com/en/product-highlight/b/bel-fuse/1xn-port-magjack-and-specialty-icms). There's classic horizontal ones with LEDs (https://www.digikey.com/en/products/detail/bel-fuse-inc/P01-0002-01/25588398). Vertical ones! (https://www.digikey.com/en/products/detail/bel-fuse-inc/P01-1AF2-01/25588382) Countersunken for low clearances (https://www.digikey.com/short/5b9mb454) As well as some nifty combo-units that contain both USB type A and Ethernet. (https://www.digikey.com/en/products/detail/bel-fuse-inc/P01-3CG3-01/25588395) Just make sure that the internal magnetics match your chipset's needs before selecting it for integration.DigiKey is in the process of stocking all the varieties, but if you want to get started, the P01-1AA2-01 (https://www.digikey.com/short/pw02p9m9) is in stock now for immediate delivery. Order today and you can get this part in your hands by tomorrow morning to help optimize your next Ethernet design!

This 1.3" round TFT display will be in the shop soon, thanks to this tester, which lets us quickly verify all functionality: We're reading a display bitmap off of the SD card, displaying it, and then pulsing the backlight. We do this all through the EYESPI connector https://www.adafruit.com/search?q=eyespi and this one is passing just fine.

Last month we stocked some fun filament shapes, like snowflakes (https://www.adafruit.com/product/6093) or unicorns (https://www.adafruit.com/product/6094) these are easy to use: simply power with 3V like any LED and they glow with a tungsten-eque warmth (but without the 120VAC or burning heat). This week we got some samples of the same COB 'chip on board' filaments but in letters and numbers! Sure we'll have to stock 36 SKUs, but how fun would it be to display custom words? You can drive these in series - 3V total with about 30mA per filament - or parallel - 30mA and 3V * n where n is the number of letters in a row.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#led #lights #glow
While developing boards, there are oftentimes we want to program ESP chips without going through the onboard USB port; this adapter will help us (and others) do that! It has a CP2102N USB-serial chip (https://www.digikey.com/short/bm7n3p5z) with RX/TX signal LEDs and two transistors wired up to the DTR/RTS line for the 'esptool standard' reset procedure technique. The output IO, plus a 3.3V 500mA regulated output, is available on a socket header, so you can plug wires in for quick programming and debugging. You can use this for everything from an ESP8266 up to the ESP32-P4! Here, we are testing it with a HUZZAH ESP8266 breakout board (https://www.adafruit.com/product/2471), one of our first Espressif chipset products.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#esp32 #adafruit #programmer

This morning, we woke up to a mechanical failure in a critical system here at the Adafruit household: our beloved dinosaur tissue holder fell off our bathroom wall and experienced a rapid, unplanned disassembly of one armature. We'll be able to fix the limb, but we want to make sure we can reattach without this happening again! Thus, in today's quest to find an excellent double-sided foam tape—let's check out what DigiKey has in store.See the chosen part on DigiKey https://www.digikey.com/short/pw3fwv20Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.comLIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/
Sparkle Motion Mini testers. The Mini came together fast, but classic testers had cascading issues. We used Claude for firmware and got cool samples, including filament letters and enclosures for Sparkle Motion Stick. And our dinosaur tissue holder fell, disassembling an arm! Time to find strong foam tape for reattachment.

This week's EYE ON NPI is spinning up to be a good one, it's the Texas Instruments DRV10974 BLDC Motor Driver (https://www.digikey.com/en/products/detail/texas-instruments/DRV10974PWPR/9091905) a simple and powerful way to add BLDC motor control to any design, with a wide operating range and all-in-one functionality so you only need a few passives to have a full feedback-ready system for fan control.We haven't used a lot of brushless DC motors - we'll call them BLDC motors - very often here at the 'fruit but that doesn't mean they aren't an essential motor you need to know about. They are the fourth of the most common DC motors people use: steppers / linear actuators, brushed DC, and servo are the others. (Technically, servos are a type of brushed or brushless DC but they're so integrated we separate them). Brushed DC motors are great for anything that has to spin fast, and if you need more torque or lower speeds just gear them down. Brushed DC motors can be driven with a low cost H-bridges (https://en.wikipedia.org/wiki/H-bridge) such as the DRV8833 (https://www.digikey.com/short/zj9p84wr). All you need is two PWM signals to set the direction and speed - you can even add an external encoder if you want to have precise speed calculations (https://www.adafruit.com/product/4416)If you have a motor that's spinning continuously, you're better off going with a brushless motor (https://en.wikipedia.org/wiki/Brushless_DC_electric_motor): these still spin around fast like a brushed DC but give up the commutation brushes. Instead, we have to toggle one of three windings in clockwise or counter-clockwise direction to move the stator around. This isn't too bad when the motor is already running, just keep toggling them and you can pretty much guarantee the speed because you're inching the stator around. However, it's harder to start the motor because you have to slowly pulse each coil and you don't know whether the fan is keeping up or falling behind. The easiest way to handle this issue is to have hall effect sensors built into or outside the motor which can detect the permanent magnet on the rotor. But this is expensive, and annoying! So instead we can take advantage of 'back EMF', (https://en.wikipedia.org/wiki/Counter-electromotive_force) the effect on each coil from the internal permanent rotor magnet as it goes around. We can use this as a method to determine the actual speed, but the techniques for doing so are way more complex than a DC or stepper motor. Instead of just applying DC voltage, you have to perform multiple steps to begin rotation from a stop: alignment, open loop acceleration, then closed loop speed control.Which is why you want an easy-to-use chip that takes care of this logic for you, like the TI DRV10974 BLDC Motor Driver (https://www.digikey.com/short/j85mb52n)! This chip abstracts away all that complex management, and provides a direction plus speed PWM pin interface so you can use it from any microcontroller. It even has built in FETs for up to 1A continuous current draw. The DRV10974 will convert the direction / PWM pins into 3 clean sinusoids with 180 degree phases for smooth and quiet motion. It can drive delta or wye motors, with 5 to 18VDC peak to peak voltages, and from 1 to 20 ohm impedance per coil.To allow the DRV10974 to drive a wide range of motors, there are three configuration resistors that let you tweak the performance in hardware. The first resistor will set the current limit from 200mA to 1.6A. The second lets you set the lead angle, a compensation for the back EMF readings (https://www.ti.com/video/6257299020001). The third will let you adjust the acceleration profile, basically letting you optimize the startup time from when we have the sensorless open-loop startup to closed-loop running. Once you've picked the motor you want to use with the DRV, follow TI's tuning guide (https://www.ti.com/lit/ug/slou505/slou505.pdf) to select the resistors for the best performance. There's also some lock-detection built in, since not having an external encoder makes it hard to know when the motor is not running anymore.For engineers that need a brushless motor driver chip that's inexpensive, and easy to integrate, the Texas Instruments DRV10974 BLDC Motor Driver (https://www.digikey.com/short/j85mb52n) is an excellent pick with plenty of stock available at DigiKey. There's also a ready-assembled eval board, the TI DRV10974EVM (https://www.digikey.com/short/0w5qpd04) available if you want to quickly test. And of course, you can pick up a BLDC motor from DigiKey as well (https://www.digikey.com/en/products/filter/motors-ac-dc/178) Order today and your electronic items will fly faster than a rotating fan blade, from Thief River Falls to your office or home so you can start developing with the DRV10974 BLDC Motor Driver (https://www.digikey.com/short/j85mb52n) by tomorrow morning.

We've been cranking out some nice stepper driver chip breakouts - the A4988 (https://www.digikey.com/short/qzmjwjvv) and the TMC2209 (https://www.digikey.com/short/p4fh9mm4) so far! We've gotten more requests for a 'brushless DC' motor driver - particularly a compact one that is sensorless and has digital control. To be honest, we've never used BLDC motors, but hey, it's never a bad time to check out a new technology. Let's see what DigiKey has for a good 'starter' BLDC: We'd like one with the internal FETs, no external sensors required, and digital speed control and configuration.See the chosen part on DigiKey https://www.digikey.com/short/mz2zcv5m-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.comLIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/
We got this kind of nifty sample of a Neopixel 'sheet,' which is uncut LED strips - the whole thing is flexible PCB material with a cuttable square pitch of 1 cm per pixel. it's arranged as a zigzag, so you can immediately use it as one strand of neopixel in a 12 x 24 arrangement. Or you could cut it into funky shapes and connect the data to data input between segments. the panel also requires 12VDC, but that's not too challenging; it could be useful when you need a flexible sheet in an unusual shape and don't want to piece together individual NeoPixel dots!

Okay, we've got our 1.3" round TFT prototype ready for testing - and here's a cute GIF of a dial turning back and forth. It's a great way to test the display, backlight, and SD card interface. We're using a QT Py ESP32 since we need quite a bit of oomph to decode GIFs and display them in real-time. With EYESPI, no wiring is required!

We got the 'big' Sparkle Motion boards (https://www.adafruit.com/product/6100) out to the PCB fab house and now are turning to the mini version. This one doesn't have USB PD or 24V support, but it is very compact and has many niceties that WLED users will enjoy...like built-in ICS-43434 microphone (https://www.adafruit.com/product/6049), however during testing, we discovered that GPIO 9 and 10 were not available because the ESP32-Mini module (https://www.espressif.com/en/module/esp32-mini-1-en) we're using has slightly different pin availability!

We're rounding the corner with testing our Sparkle Motion (https://www.adafruit.com/product/6100) WLED-compatible board. We're doing the audio-reactive test with the built-in I2S microphone this time. This digital mic will give great audio quality without needing any extra work. If you want an external mic wired far away, there are GPIOs exposed that you can solder to for another I2S connection - ESP32 lets you use any pins, which is nice! this demo is a graphical equalizer that makes verification easy! All we have left is to test the IR remote and fuse, and we're good to go!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#wled #music #sound
This chonky neopixel tube is a treat with full, smooth color all the way around - but it's also a real pain to drive, given it requires 24V power. Or at least it would be if we didn't have this Sparkle Motion (https://www.adafruit.com/product/6100) board we are testing! With USB PD support, it's easy to plug the board into a USB C laptop power supply that can provide 20V at up to 5A - even though it's under 24V, we've found the LEDs are just as bright. Looks great, we're going to keep testing and get these boards ordered, hopefully before the year's end!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#wled #led #art
We're rounding the corner with testing our Sparkle Motion (https://www.adafruit.com/product/6100) WLED-compatible board. This time, we're doing the fuse test. we got a lot of requests to include a 5A fuse onboard. Of course, we need to verify that it works as expected. With a chonky 12V 25A power supply and my trusty electronic load, we dial up one amp at a time... note that all PTC fuses have a 'hold' of 5A and a higher trip current of ~2x that, so we actually open at 10A. Once it heats up a bit, that trip current can drop a bit, but it will always be over 5A and under 10A. Good test equipment makes this job nice and easy. The board is complete - time to book it up, just in time for the New Year.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#wled #led #art
aaannnddd they are cuttable-cut-to-size ✂️ The nOOds we've been stocking in the adafruit shop (https://www.adafruit.com/search?q=noods) have been 'power through' type - positive at one end, negative on the other. We've had some requests for nOOds that can be powered from just one end, especially for decorative purposes, and here are some samples we're checking out! These nOOds use an FPC with two solderable/clippable contacts at a single end, and the other end has a melted-off end. The downside is that they are a bit brighter at the head than the tail, but it's not too bad.#noods #singleended #ledstripsVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

Playing with our new Sparkle Motion board that's coming soon (https://www.adafruit.com/product/6100) we wanted to try driving a large display of LEDs and discovered that once you want to do custom display graphics, WLED is not super great. Instead, you can use the open source and free xLights software (https://xlights.org/) which is completely amazing and has a learning curve like a cliff for the first 30 minutes. BUT once you get your controller and layout, it's unbelievably powerful and actually kinda easy to get going with simple display work. It also has a very satisfying preview mode.#wled #led #neopixel Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
Since the latest release of 'piolib' we can do things like drive NeoPixels on any pin on the Raspberry Pi 5 (https://learn.adafruit.com/circuitpython-on-raspberrypi-linux/using-neopixels-on-the-pi-5) which rocks, and means we can tackle the next, more complex, project: driving HUB75 RGB Matrix displays (https://www.adafruit.com/product/5362) these require even MORE timing freakiness: using 10 pins, and 'manual' PWM means we have to constantly blit out the color dithering. Historically this was done with mmap'd memory to the GPIO controller bitbanging, which required a full core and could jitter depending on load. But now we can use the PIO peripheral! We can drive massive display arrays at high speeds and color depths using just about any pins.

We got our WLED-friend PCBs today, and we only made one mistake: the wrong resistor on the 3.3V feedback line. Now that it's fixed, the board seems to work great with the latest version of WLED (https://kno.wled.ge/basics/tutorials/)! we are checking all 4 signal outputs with this handy 256-LED grid that sits on our desk. Next, we will test the onboard IR receiver, USB PD, I2S microphone, extra I/O pins, and I2C. We'll also do an Arduino IDE board definition in case folks want to use it as a generic ESP32-to-LED-driver board. We're calling the board "Sparkle Motion" for now, but if you have other naming ideas, let us know - if we pick your name, you get a free board (https://www.adafruit.com/product/6100).

We got our WLED-friend PCBs (https://blog.adafruit.com/2024/12/02/leftovers-layout-wled-board-revision-a-completed/) and are testing it with various LED grids. First, we tried out a 16x16 NeoPixel grid that runs on 5V. Since that worked well, we're now onto a much bigger 60 x 60 grid - that's 3,600 LEDs! These are some NeoPixel pebble (https://www.adafruit.com/product/6024) netting samples we're also testing at the same time; each one has 20 x 60 pixels and uses 12V power, so it's a good test of the DC pass-through for higher voltages. Since WLED has a limit of 2000 pixels per output, this demo uses the three output ports that are then 'merged' together in memory to make a single large grid. We have more to test soon: the onboard IR receiver, USB PD, I2S microphone, extra I/O pins, and I2C, so watch for those videos as they come together.

This week's EYE ON NPI is an EYE ON A PI - it's the Raspberry Pi Compute Module 5 (https://www.digikey.com/en/product-highlight/r/raspberry-pi/raspberry-pi-compute-module-5), the latest update to the easily embeddable mini modules that make industrial developers happy by giving them all the power of a Pi 5 in a ready-to-go pluggable solution.The Raspberry Pi computer launched with the goal of bringing low cost computing to the education market (https://www.bbc.co.uk/blogs/thereporters/rorycellanjones/2011/05/a_15_computer_to_inspire_young.html) and through the Pi Foundation (https://www.raspberrypi.org/) they still have that charitable goal (https://static.raspberrypi.org/files/about/RaspberryPiFoundationStrategy2025.pdf) while also spinning off the manufacturing/sales company into the Trading Company which went public this year (https://www.raspberrypi.org/blog/what-would-an-ipo-mean-for-the-raspberry-pi-foundation/). The first few Raspberry Pi computers were 'all in one' style (https://www.adafruit.com/product/1344), with power, GPIO, Video and Audio output, USB, Ethernet, and Micro SD card storage (https://raspi.tv/2018/new-raspberry-pi-family-photo-including-pi3a-plus-zero-wh). Eventually enough folks asked for an enclosure-friendly version that would allow an "I/O" board to be designed with the ports in a different arrangement - the big-sized-Pis have them arrayed over 3 sides. To solve this conundrum, and to satisfy the growing industrial/commercial market, the Pi engineers designed the Compute Module 1 which is still available (https://www.raspberrypi.com/products/compute-module-1/). This clever SODIMM packaged board has all the GPIO and peripheral pins on a plug-in connector so you can slot it into an existing design securely and easily - SODIMM sockets (https://www.digikey.com/short/rz9cdjrn) come both vertical and horizontal. This was later updated to the CM3 and CM3+ (https://www.digikey.com/en/products/detail/raspberry-pi/SC0149/9866293) which was on par with the Pi 3 instead of the Pi 1, with significantly higher computational power.However, perhaps because they wanted a more compact module, or to support high-frequency signals better, the next generation of Compute Module 4's (https://www.digikey.com/short/wffzdn0b) came in a flat rectangular shape with dual 100-pin Hirose contacts. (https://www.digikey.com/short/5m8djf0t) Another nice thing that happened with the CM4 is it became available in dozens of configurations: 1/2/4/8 GB RAM, SD or 8/16/32GB MMC, and with or without WiFi/BLE/BT. This allowed commercial users to go with the 'lowest cost option' needed to fulfill their requirements - whereas the Pi 4 comes in only 3 or 4 RAM options (https://www.digikey.com/short/4pn5vw24). The ready-to-go software - no kernel compiling or OpenWRT configuration required! Long-term hardware support and low prices pushed the CM4 into more and more designs. Which brings us to the NPI of the week, the Compute Module 5 (https://www.digikey.com/en/product-highlight/r/raspberry-pi/raspberry-pi-compute-module-5)! The CM5 is a big upgrade, with quad A76s at 2.4GHz for a 2x computing upgrade, increased RAM options of up to 16G, increased MMC option of 64GB, USB 3.0 ports, PCIe and RP1 hardware interfacing with PIO support (https://www.raspberrypi.com/news/piolib-a-userspace-library-for-pio-control/). If you have an existing CM4 design, you can easily upgrade or update to the new hotness. If you're new to integrating Raspberry pi, then while you may think of the Pi as a hobby/school computer, that isn't necessarily true anymore with 72% of Pi computers sold going into commercial/industrial use (https://investors.raspberrypi.com/ipo/documents/1). That means you can be confident that you'll get consistent pricing and availability for a long time so that you can work on designing the rest of your product for the CM series to plug into. And like the CM4, the CM5 is available in a variety of configurations and prices, from $45 to $135.Raspberry Pi Compute Module 5's are currently only available for pre-order (https://www.digikey.com/en/product-highlight/r/raspberry-pi/raspberry-pi-compute-module-5) , with estimated ship times in Q1 of 2025 to DigiKey - and the moment DigiKey gets some in stock, they'll ship your pre-order instantly so you can get integrating with the Pi ecosystem the very next day. Don't wait till release day because they'll sell out instantly! Instead, when you pre-order from DigiKey, your order goes into a queue and you'll get first-come-first-served prioritization.See more on DigiKey https://www.digikey.com/short/47t12drj

We got this nifty panel-mount cable with a combo action: both USB C and DVI/HDMI connectors on both ends. This could be handy for single-board computers like Raspberry Pi's or our RP2040/RP2350 boards with DVI outputs (https://www.adafruit.com/product/5710). Since we're testing our Metro RP2350 with HSTX/DVI output anyway, this is a good time to test the cable out - some things we test with USB C cables: verify it enumerates in all 4 orientations (ya never know) and check it with a USB PD sink that requests various voltages. So far, so good; we'll get some of these into the shop in the next few weeks.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#usb #usbc #hdmi

This week we got our Metro RP2350 boards (https://blog.adafruit.com/2024/11/11/metro-rp2350-now-with-bigger-better-rp2350b/) back and after fixing the pin direction and rerouting (https://www.instagram.com/adafruit/p/DC2U7mdyf9W) the whole thing, it came up and pretty much works perfectly! Just one component needed a swap - we were able to test all GPIO, analog inputs, MicroSD slot, PSRAM, LEDs & NeoPixel, user button, I2C/SPI/UART, aaand power supplies. The 5V supply is great, we got a nice clean 5V out at 2A+ from 12V DC in. The last thing to check is the HSTX port, which gives us DVI access, and it works, thanks to this festive turtle demo!

We've been testing the Trinamic/Maxim/Analog/WeylandYutani TMC2209 (https://www.digikey.com/short/8r5m38h8) breakout we designed, and it's working great - the step/dir interface plus the micro-step select allows a microcontroller to control a stepper with just GPIO and true-to-its-name it is a very silent stepper driver, much quieter than the A4988 (https://www.digikey.com/short/tfjt88dd)! There are a few different I/O pins on the TMC: Index tells you when a full step is completed, which is handy to know when you want to change stepper modes on the fly. Diag lets you know when a power or motor failure has occurred. It can also tell when the motor has stalled if it's configured to. Finally, and most interestingly, is the UART interface: this unidirectional pin lets you read and write configuration registers, set 1-128 microsteps, change current limiting, and detect stalls for 'auto homing'. So far, everything works; we're just going to swap the direction of the potentiometer so it twists clockwise to increase the current limit and book PCBs!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#tmc2209 #steppermotordriver #silentdriver

We're wrapping up our WLED board design (https://www.youtube.com/watch?v=M4Ybd8CdQYM) and the last part we need to spec out is the 3.3V regulator. Since we are utilizing USB PD or DC in, we could be running from 5V ~ 24VDC. For the 5V output, we only need a few mA, so we're going to pick the same LDO family we sourced earlier (https://www.youtube.com/watch?v=H_0Kua2UZCs) but for the 3.3V we need at least 500mA of current for the ESP32 chip, so a switching supply is necessary!

We've always wanted a portable scope cart (https://vintagetek.org/scope-carts/) for our workspace to have our test equipment either by the desk for firmware work or at the soldering worktable for rework debugging. At our new office, we finally have space for one! We picked up this 'dental cart' (https://www.amazon.com/dp/B0DM8P2PDT) - It is not super fancy, but it is metal, and it came together fairly easily. We like the mini top shelf for the scope and the second shelf underneath for the power supply and electronic load. The drawer can hold leads or probes. We've locked it next to our desk so we have more desktop space, and it's easy to peek over as we bring up new boards like the metro RP2350 (https://www.adafruit.com/product/6003). We'll also get the VGA output into our video streaming setup to show off signals we're working on.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#ladyada #scopecart #electronicsworkbench

Ladyada tasked Jepler with exploring the new libPIO for Raspberry Pi 5 computers: this gives us access to the RP1 chip so that we can run custom PIO state machines on the GPIO pins. A common use case is NeoPixels, because of the tight timing requirements of the WS281x LEDs. Here is our first light test that shows it is possible...Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#raspberrypi #adafruit #pio
This coming year, we wanted to update our storage and organization: with about 700 original designs, a couple dozen in progress, and thousands of items in the shop, it's hard to keep track of all the components and devboards we need to test various combinations. Historically, we've used double-sided totes (https://www.adafruit.com/product/1149), which are good, but the double-sidedness is a bit annoying, or the little divider boxes for small breakouts (https://www.adafruit.com/product/2938), and snap-top boxes for SMT components (https://www.adafruit.com/search?q=modular+snap). But all these cases were sort of swimming around, and it was getting unwieldy. We're going to try to use the large IKEA ALEX drawers (https://www.ikea.com/us/en/p/alex-drawer-unit-on-casters-gray-turquoise-50483449/#content) - we like them cause they're wide and thin - and maybe use something like gridfinity (https://gridfinity.xyz/) to make a flat storage surface so we can quickly find any PCB or part we need.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
We've sold stacking headers (https://www.adafruit.com/search?q=stacking) for a looooong time - longer than the pins' tails, which allow them to stack shields or daughterboards of various kinds. The kind we have are about 0.4mm by 0.6mm, but we got a request to carry 'square' pin versions that will seat better in solderless breadboards and loose sockets. The samples we got are gold flash and 0.62'ish mm square, and they seem pretty good! we'll swap to use these next time we book an order.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#electronics #makers #soldering

Hot off the PIO-presses, our resident Jepler created a Python binding for the Raspberry Pi 5 that lets us use the RP1 chip (https://www.raspberrypi.com/news/rp1-the-silicon-controlling-raspberry-pi-5-i-o-designed-here-at-raspberry-pi/) on the 5/500 series boards to drive Neopixels using PIO. This is great because we can now use Neopixels (https://www.adafruit.com/category/168) and friends on the latest Pi boards, and we can use any pin because PIO is not limited by underlying peripherals. You do need the latest kernel and firmware, so it is not quite ready for prime-time, but once piolib (https://github.com/raspberrypi/utils/tree/master/piolib) is more readily available, we'll be able to have folks test this out.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#raspberrypi #NeoPixels #Python

In our WLED design, we want to have two (or maybe three?) DC power inputs, where each can be up to 24V, and supply up to 5A of current into the LED strands. In our typical designs, like the Metro or Feather series, we don't really go above 1A or 2A and 20V. Let's take a look at what is available: we want to have the lowest possible forward drop because, at 5V, we want to have no less than 4.5V going into the LEDs, but we also want to minimize the reverse current which can start to get non-trivial at these capacities. Also, should we go with an 'ideal' diode chip or with a Schottky diode?See the chosen part on DigiKey https://www.digikey.com/short/zq72b5bq-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.comLIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/

This week's EYE ON NPI is gland-tascular it's Amphenol's EMC Cable Glands (https://www.digikey.com/en/product-highlight/a/amphenol-ltw/emc-cable-glands) a two-in-one product that provides electrical connectivity for shielding as well as waterproofing for harsh and wet environments. Amphenol has 3 variants available, that will cover from 7 to 17mm cable diameters, and will provide IP68 protection when properly installed.Once makers finish their prototypes on the bench, it's time to turn a bunch of breakouts and breadboards into a finished PCB. That will clean up the loose jumper wires, but it still isn't ready for customer usage. For that we need an enclosure - something we chatted about in the last EYE ON NPI (https://blog.adafruit.com/2024/11/21/eye-on-npi-wurth-elektronik-smd-spacers-eyeonnpi-digikey-digikey-adafruit/). Most enclosures for electronic devices that you'll encounter as a consumer are injection molded or maybe bent-metal, both are durable and fully custom, but have high setup costs which makes them only practical if you are planning on selling over 10,000 pieces. As an industrial designer, you may have to design for max lifetime of 500 pieces. In this case, it may be better to use an off-the-shelf enclosure such as those available from DigiKey (https://www.digikey.com/en/products/category/boxes-enclosures-racks/27). These come in basic rectangular shapes, with mounting holes, and plastic/glass panels. But one problem is that if you want to attach external cabling like USB, Ethernet, CAN, or power, you need to cut perfect slots. Also, those connectors wont be weatherproof. Thus, cable glands! (https://www.digikey.com/en/products/filter/cable-and-cord-grips)Cable glands are like four cable management (https://en.wikipedia.org/wiki/Cable_management) solutions in one: they provide strain relief, they allow clean cabling into an enclosure, they are weather or waterproof, and for the EMC series, they also provide ground shielding connectivity to an enclosure. Assembly and is pretty simple (https://learn.adafruit.com/air-quality-sensor-silo-house/assembly). First, drill a hole to match the datasheet template. Insert the first piece with the round gland part facing out. Lightly attach the mounting nut to keep it in place. Thread the cable through and tighten until the inner rubber gasket makes a seal against the cable. If properly installed, you'll get IP68 (https://www.iec.ch/ip-ratings) protection against dust and water. The only thing you have to check for is that the gland specification matches the outer diameter of the cable: too small and you'll crack the gland when tightening it, too large and the gland wont make a proper seal.There's three variants of the EMC Cable Glands (https://www.digikey.com/en/product-highlight/a/amphenol-ltw/emc-cable-glands), and all three are in stock right now for immediate shipment! If you don't need metal shielding, DigiKey stocks a wide variety of other cable glands from Amphenol (https://www.digikey.com/short/7w8vq5jj) for any size cable and enclosure. Order your glands today from DigiKey and they'll ship instantly so that you can start ruggedizing your next enclosure by tomorrow afternoon.See on DigiKey at https://www.digikey.com/short/7ddhh2dt

We just had a turkey nap and are now back to work. These vertical-mount 1.14" IPS TFT displays have 240 x 135 pixels and are 'stackable' horizontally on a breadboard or perfboard. There are just enough pins to control the TFT and backlight, so if you want to individually control each display, just have them share the SPI and DC pins, then have a unique chip select pin for each. These could make for cute 'flip' display simulations or faux nixie bulbs. The prototypes work fine; we just need to adjust the slot size. The panelized PCBs can be booked, and there is pie.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#newxie #prototype #success
While waiting for the turkey to finish brining, we’re designing a board for using WLED – and we want to make like the bestest board in the whole world.Our resident mermaid, firepixie, makes a lot of projects with WLED, and she loves it! So, how can we make something that will be powerful but not too bulky? Here are some things we’re thinking about as the design starts to congeal like cranberry sauce:Power via USB Type C PD with a slide switch that selects between 5, 12, and 20V (24V pixels can usually run fine at 20V) OR via a 2.1mm DC jack. With ideal diodes, it’s good for up to 5A from either.ESP32-Mini module with built-in or optional wFL antenna port. The classic ’32 has broad support, even if we’d prefer the ‘S2 or ‘S3.There are three output signal terminal block sets, with power and ground for each. They’ll be level-shifted to 5V.Built in I2S microphone (we’re still pondering this one).Stemma QT I2C port to connect external sensors/OLEDs/etc.; separate analog/digital input JST port.1.3″x1.75″ / 33mm x 45mm size with mounting holes.Anything we’re missing, anything that’s extraneous?============================Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#wled #led #diy

We got a suggestion from our Friend to make a board that plugs onto the back of a NEMA stepper motor with one of these drivers (https://learn.adafruit.com/all-about-stepper-motors) which is a nifty idea that we've seen before (https://gitlab.cba.mit.edu/quentinbolsee/tmc2209-xiao-rp2040): you minimize wire length and EMI because the high current/high-frequency signal is only going a few cm. Just watch out for your chip; you've got good heat sinking. There are standard sizes for steppers (https://learn.adafruit.com/all-about-stepper-motors), so let's check out what NEMA motors are available at DigiKey for us to model.See the chosen part on DigiKey https://www.digikey.com/short/r5vnqcmd-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.comLIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/
We just got the OK to put the Pico 2 W in the shop. You can pick it up at https://www.adafruit.com/product/6087, and you might be wondering: hey, do you have CircuitPython built for it? The answer is YES! We have secretly added support, and v9.1.2 has a build ready. We'll be adding it to the https://circuitpython.org/downloads downloads page shortly, but if you've got one in hand before launch somehow, you can check out the builds in the Absolute Latest S3 Bucket (https://adafruit-circuit-python.s3.amazonaws.com/index.html?prefix=bin/raspberry_pi_pico2_w/en_US/) the pico 2w is a great upgrade with twice the speed, twice the SRAM and twice the flash memory, solving many frustrations folks had with the original Pico W.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#raspberrypi #pico2w #adafruit

We got our Allegro A4988 stepper driver breakout PCBs back and are ready to test them. First, we verified that STEP and DIR worked (yes!) and that the LEDs lit (yes, but we need to tweak the resistors to make the brightness even). Then we tried all of the stepper-settings, you can select 1, 4, 8, or 16-microsteps. All the sleep/reset/enable pins work. Finally, we checked the current limiting functionality with a potentiometer that can be twisted to select up to 2A current per coil. This directly affects the torque, so it's easy to test by verifying that we can stall the motor with hands or vise-grips. We'll order these with 2oz copper and get them into production next!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#a4988 #stepperdriver #electronics

This week's EYE ON NPI is super spacey - it's Wurth Elektronik SMD Spacers (https://www.digikey.com/en/product-highlight/w/wurth-electronics/smd-spacers) a variety of pick-and-place-able hardware components that solder directly to your PCB designs during in a standard SMT line, and speed up your assembly and simplify your mechanical design.The first thing you'll learn as an engineer is that not only do you need to worry about your schematic being correct, and the layout being manufacturable and optimal for signal and power integrity, but you also have to make sure it fits into whatever enclosure the mechanical engineer cooked up. Worse, sometimes that mechanical engineer is you! For example, a common design requirement is to have a front panel, and then you have to mount the PCB against it with standoffs or spacers (https://en.wikipedia.org/wiki/Spacers_and_standoffs) so that the buttons, knobs and switches are accessible but protected. We used this technique with the first Adafruit product x0xb0x (https://www.ladyada.net/make/x0xb0x/fab/finish/index.html) - in this case we used hex standoffs (https://www.digikey.com/en/products/filter/board-spacers-standoffs/582). These come in a vast array of configurations, lengths and threads. There's female-female, female/male and even unthreaded ones. By mixing and matching, plus adding machine screws and lock washers you can construct any sandwich of PCBs.Standoffs work great, but they add a lot of time to the assembly process: they have to be manually lined up with the PCB holes, they need lock washers to keep them from rotating in place, and they can fall into the enclosure during assembly or repair. Being metal that means shorting against all your nice PCBA components! That's why we're big fans of SMT solder-able standoffs. We've used them in our designs like the Adafruit Macropad (https://www.digikey.com/en/products/detail/adafruit-industries-llc/5128/14635377) and Memento (https://www.adafruit.com/product/5420) camera. We love that they come on pick and place reel, with pickup tabs, and solder nicely in place using a standard SMT processing method. They always have the same uniform height, same location, and will not twist when attaching the machine screws on the other side.The Wurth Elektronik SMD spacers (https://www.digikey.com/en/product-highlight/w/wurth-electronics/smd-spacers) are available in a huge variety of configurations. For the threaded type: lengths from 1mm to 15mm and M2, M2.5 or M3 thread. For unthreaded spacers, hole diameters of 2.25mm, 2.7mm or 3.3mm. They also have male-thread spacers (https://www.digikey.com/short/bchz92w0), and the REDCUBE WP-SMRA series (https://www.digikey.com/short/mbnzwrvz) right-angle spacers which are brilliant and should allow for full-sided enclosures without wrangling. Which we've never seen before! If you want to try the full range, pick up a SMT Spacer Design Kit (https://www.digikey.com/en/products/detail/w%C3%BCrth-elektronik/977990/5965155). All are available on tape and reel / cut-tape and are in stock at DigiKey for immediate shipment. Order today and you can start integrating these stand-offs into your next PCB design.See the parts on DigiKey https://www.digikey.com/short/cpvn4db7Video: https://www.youtube.com/watch?v=xr4CVYb8nTEVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week on the Great Search, we're following up on our Metro RP2350 (https://blog.adafruit.com/2024/11/11/metro-rp2350-now-with-bigger-better-rp2350b) design we showed off last week.One thing we designed in is plenty of space around the NOR Flash chip (https://blog.adafruit.com/2020/09/29/the-great-search-spi-nor-flash-memory-thegreatsearch-digikey-adafruit/) and PSRAM so that we can clip on a debugging probe. But what is a SOIC debugging probe? These 8-probes-in-one-clamp are a brilliant solution when debugging or for in-circuit-programming. When looking for one, we'll want to make sure that it can grab onto 0.3" wide SOICs, not just 0.15" wide.See the chosen part on Digikey https://www.digikey.com/short/f2wnjb8q#deskofladyada #sampleprojects #solarpower #hardwaredesign #electronicsengineering #usbbooster #greatsearch #rp2350 #norflash #psram #debuggingtools #soicclip #openhardware #adafruit #electronicsprojects #prototyping #techtesting #electronicsmaker #diyengineering #holidaydisplayVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is another great step forward in Bluetooth Low Energy development, it's Nordic's new nRF54 series (https://www.digikey.com/en/product-highlight/n/nordic-semi/nrf54l15-multiprotocol-soc) and nRF54L15 Wireless SoC Development Kit (https://www.digikey.com/en/product-highlight/n/nordic-semi/nrf54l15-wireless-soc-development-kit). This is the heir-apparent to the popular nRF52840 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52840-CKAA-R/15929796) series chip which we know and love so much. The nRF54 series comes in L and H variants, for 'low' and 'high' power, but even the L series is a step up, with Cortex M33 running at 128MHz, and up to 1.5MB ReRAM (https://en.wikipedia.org/wiki/Resistive_random-access_memory) / 256KB SRAM. The H series is a whole new ball-game with dual M33 running at 320MHz, 2MB of ReRAM and 1MB of SRAM plus upgraded peripherals.Wow, the nRF series has come such a long way from the baby-steps of the SPI-peripheral nRF8001 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF8001-R2Q32-T/4626390) to the early ARM Cortex M0 plus BLE combo chip, the nRF51 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF51822-QFAB-R7/4626396). We still use that nRF51 in many of our Bluetooth LE boards like the Feather 32u4 and M0 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/2995/5823444), also as a SPI-peripheral-to-BLE converter. The next big upgrade was the nRF52832 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52832-QFAB-R/6051565) which bumped the processor from an M0 to an M4, but didn't do a huge bump to the Flash or SRAM compared the nRF51. The big leap after that was the nRF52840 which is still an amazing chip: USB peripheral means you can use this chip as the main processor, and it can do all your processing, user interface, sensor reading and wireless communication with only a few passives to support it. There was an nRF5340 released about two years ago (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF5340-CLAA-R/14323741) but much like Windows releases, we tend to skip every other chip.We happened to check digikey.com/new yesterday and saw the nRF54L (https://www.digikey.com/short/zf8pz0cr) series pop up, which is exciting as it was pre-announced about a year ago (https://www.youtube.com/watch?v=XG8bRNaNHrg) and is now shipping to customers! The nRF54L (https://www.digikey.com/short/zf8pz0cr) comes in three variants, which is not surprising because we've seen earlier chips come in 'lite' versions that cut pricing by having less flash or RAM. All variants have a 128MHz Cortex M33 with a RISC-V co-processor, and a BLE stack. One interesting thing we noted, is that instead of flash memory, which is big and expensive and hard to do with modern fab processes, the nRF54 uses ReRAM (https://en.wikipedia.org/wiki/Resistive_random-access_memory) which is non-volatile and uses memristor technology, which is pretty cool! The nRF54 series supports BLE 6, one new capability is channel sounding (https://en.wikipedia.org/wiki/Channel_sounding) which will improve the ability of phones to locate 'find my' tags that have become such a popular usage for the nRF chipset. Traditionally, the nRF52 chips in these tags use RSSI to measure approximate distance. There's been some improvements on the technology such as Angle-of-Attack that was introduced in BLE 5.1 (https://www.youtube.com/watch?v=EosGQtGioiY) but now with a broad-sprectrum burst it's looking like some of the lessons from UWB (https://blog.adafruit.com/2024/03/15/sera-nx040-ultra-wide-band-and-bluetooth-combo-module-eyeonnpi-digikey-digikey-lairdconnect-adafruit/) are being integrated to the BLE specification to improve item location.The nRF54L series is launching with the L15 variant (https://www.digikey.com/short/rd9fr19f), that's the one with the most memory, so it's a good start: once you have your design settled you can transition to the smallest chip you can get away with. They're coming into stock shortly so sign up at DigiKey to get notified when the package you're looking for arrives. While you wait, you can order up one of the nRF54L15-DK (https://www.digikey.com/short/qvhqv85q) dev kits, which are only $39 and in stock right now for immediate shipment. Order today and you'll get everything you need to start developing the nRF54 (https://www.nordicsemi.com/Products/Development-hardware/nRF54L15-DK) - a built in debugger, power management chip, broken out GPIO, user buttons and LEDs. While you wait for your dev kit to arrive, you can start thinking about the nRF54H series (https://www.nordicsemi.com/Products/nRF54H20) which is the high-end chip with dual M33 running at 320 MHz, 1 MB of SRAM, 2MB of ReRAM , high speed USB and I3C support (https://www.youtube.com/watch?v=hC4zkvdVag4)!

We had a request to stock more stepper driver boards, and they've got a point: we have a few brushed DC driver boards based on chips like the DRV8833 (https://www.digikey.com/short/z14mb55f) but no dedicated chips like the Trinamic's (https://blog.adafruit.com/2020/06/18/eye-on-npi-tmc2226-sa-ultra-silent-stepper-motor-driver-eyeonnpi-digikey-adafruit-digikey-adafruit-trinamic_mc/). We started a design with the 'classic' A4988 (https://www.digikey.com/short/hfz0ttv5), but it's been many years since that chip was released, let's find another option that has microstepping, and can drive stepper motors at 5V.See the chosen part on DigiKey https://www.digikey.com/short/wzbp7rwp-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.comLIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is Perfect and Looking Cool - We're checking out the Arduino Opta line of programmable PLCs (https://www.digikey.com/en/product-highlight/a/arduino/opta-expansions). PLC stands for "programmable logic controller" (https://en.wikipedia.org/wiki/Programmable_logic_controller) and these devices are used in manufacturing and robotics to automate sensor inputs and robotic control outputs in factories. Because of dependable PLC performance, your food, clothing, medicine and water are affordable and high quality, with repeatable results. Manufacturing engineers have used PLCs since the 80's, and they've been essential for the 3rd Industrial Revolution (https://en.wikipedia.org/wiki/Information_Age). If in the second industrial revolution moved us from individually-manufactured handmade goods (https://en.wikipedia.org/wiki/Handicraft) to assembly-line repeatability (https://en.wikipedia.org/wiki/Assembly_line), then the information age and PLCs took us from the back-breaking work of doing the same task day-in-day-out to robots (https://www.youtube.com/watch?v=CjL_dQ5HAAg). Tasks like: measuring out the exact weight or count of product, applying labels, heating to temperature and holding it there for 45 minutes. While designing the machines that do this automatically is also time-consuming expensive, it's something you only have to do once.The Opta was designed in collaboration with Finder, (https://opta.findernet.com/en/) an Italian company like Arduino, which specializes in PLC design. This is a great team-up because Finder already had a family automation products and tools, so it has the industrial experience whereas Arduino has the IDE, cloud and PCB-design skills to bring in the user experience. The Opta family looks like a classic PLC, with screw terminal inputs and outputs. There are LEDs embedded to the case that can be controlled, as well as analog inputs, digital IO and built in power relays. All of the IO ports have wide voltage ranges like 0-10V and are well protected from under/over-volting, short-circuiting or ESD. Inside is an STM32H747XI (https://www.digikey.com/short/hzr2rnv2), a ultra-powerful Cortex M7 @ 480MHz + Cortex M4 @ 240MHz chip with a ton of SRAM and Flash. It can easily run an entire factory! Some versions have WiFi, Ethernet, or RS-485 for connectivity - however they are all designed to run standalone.Traditional PLCs are completely opaque, to the point where you have to use only the proprietary software that the vendor provides. What's nice about the Opta (https://www.digikey.com/short/jbb74j41) is you get to use the Arduino IDE, which has integrated support with a couple different programming systems. (https://docs.arduino.cc/software/plc-ide/tutorials/plc-programming-introduction/) You can of course use the classic Arduino sketch system (https://opta.findernet.com/en/tutorial/getting-started) and use digitalWrite(), analogRead() and all the other C++ capabilities of the classic IDE. But you can also use the classic "IEC 61131-3 programming languages" (https://en.wikipedia.org/wiki/IEC_61131-3), Structured Text ST, Instruction List IL, Ladder Diagram LD, Sequential Function Chart SFC, and Function Block Diagram FBD. These are somewhat archaic languages, but many mechanical engineers are trained in their use, so the Opta is a nice transitionary device. There's also expansion options so if you want more digital input pins and relays, you can plug a port on (https://www.digikey.com/en/product-highlight/a/arduino/opta-expansions) which will give you 16 more inputs and 8 more SSR or electromechanial relay outputs.If you've ever been curious about how PLCs work, or if you want to maintain, upgrade or repair factory equiptment, the Arduino + Finder Opta (https://www.digikey.com/short/jbb74j41) is an great product which will let you replicate the microcontroller experience to industrial automation. And best of all, it's in stock right now at DigiKey! Order today and DigiKey will ship your Opta immediately so that you can be manufacturing the future by tomorrow afternoon.

Get spooky this year with a magical halloween coffin that holds a surprise inside. A 2-way mirror and an array of animated lights creates a face-blending illusion, melting your face into a creepy skeleton or other Halloween monster. You can also prop this up and blend two human faces together, creating a very creepy and surreal experience. This project requires a little soldering and some software installation, but no coding. We're using an ESP32 Feather board to program and control our lights over WiFi, so you can control and change the colors or animations with your smart phone or any web-enabled browser.

We covered a DMX transceiver on EYE ON NPI (https://www.youtube.com/watch?app=desktop&v=X12v_qLC4-M) a few weeks ago, and after learning about how DMX works, we decided to make a DMX FeatherWing much like the MIDI 'Wing (https://www.adafruit.comproduct/4740). We'll need a chip, a hardware UART, and a couple of GPIOs. We'll also need two DIN connectors, one for the input and one for the output. We're sure that we can get some simple through-hole components through DigiKey; let's look for both the "input" and "output" directions for the DMX connectors.See the chosen part on DigiKey https://www.digikey.com/short/d4mnrr59-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.comLIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/

Following up on our last Great Search for a DMX / XLR connector, our next step is to find a DMX transceiver. We started by looking at official and common DMX shields for Arduino since we know there's a ton out there, including the semi-official TinkerKit brand (https://web.archive.org/web/20140727121929/http://www.tinkerkit.com/dmx-master-shield/). These boards all use the MAX485 (https://www.digikey.com/short/q7mbb9bj) and XLR connectors. They often don't have isolation or transient voltage protection. While the MAX485 is readily available, let's look at some other options that might work out for our design, especially if they have isolation built in!See the chosen part on DigiKey https://www.digikey.com/short/v722r81q-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.comLIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/dmxtransceiver, electronicsdesign, dmxlighting, isolatedtransceiver, electronicsengineering, serialcommunication, rs485, max485, diylighting, embeddedprojects, arduinohacks, diyengineering, lightingdesign, techsearch, automationdesign, industrialautomation, hardwaredesign, circuits, makerspace, partsearch

With a resolution of 160x120 pixels, remote temperature measurements of -40°C to +300°C, and the size of a coin, this camera can be embedded into any kind of product, whether it's running Linux, RTOS or a plain old microcontroller. Thermal cameras are multi-purpose, with usage in medical, industrial, construction, maintenance and security industries. Use them to make sure equipment is running at the right temperature and not overheating, that insulation for a room is performing adequately, locating people or animals, or detecting fevers without touching. FLIR makes the best low-cost, small-size thermal cameras and they're available off-the-shelf at DigiKey for quick integration. Each camera outputs either a simple grayscale-valued frame or one with a false-color RGB888 palette - the palette can be configured over I2C.The Lepton 3.1R is one of a series of cameras available from FLIR, including the Lepton 2 and 3.5. What's great is all have the same physical pinout and shape that can plug into a socket. This is great for manufacturing yield and field repair: the expensive module is placed last in the manufacturing line so earlier yield issues don't affect it. Also you can swap different resolution/FOV modules to customize for the end-user. For example, the Lepton 2 (https://www.digikey.com/en/products/detail/flir-lepton/500-0763-01/6250105) is a little less expensive but has only 80x60 pixels. Or you can upgrade to the Lepton 3.5 (https://www.digikey.com/en/products/detail/flir-lepton/500-0771-01/7606616) with similar resolution but a narrower FOV. Note that the FOV will affect the distortion greatly: a wider FOV requires a lens to focus the IR emissions but will fisheye the middle and compress the edges. There's software from Teledyne FLIR (https://www.flir.com/developer/lepton-integration/lepton-3.1r-dewarping-application-note/) that will "de-warp" the 3.1R's output, using Open CV, to give you more realistic imagery.To learn how to work with these modules, we recommend the Lepton engineering integration guide (https://flir.netx.net/file/asset/13333/original/attachment). Unlike the simplest thermal camera modules and sensors, which use only I2C, or the most complex USB-video output devices, the Leptons use a combination on I2C for configuration - called the CCI Command and Control Interface - and SPI for VoSPI - a.k.a. video over SPI. This makes them possible to integrate with a wide range of microcontrollers or microcomputers. As mentioned before, you don't solder the cameras to the PCB. Instead they are plugged into a common Molex 1050281001 socket (https://www.digikey.com/en/products/detail/molex/1050281001/3045223) which is only $1 at DigiKey and comes on a pick-and-place reel.If you want to get started very quickly, DigiKey and GroupGets (https://www.digikey.com/en/supplier-centers/groupgets) have partnered up to offer a wide range of breakout boards, USB adapters and dev-boards that feature the Teledyne FLIR Leptons (https://www.digikey.com/short/2djrnzpr) GroupGets also published firmware and example code (https://github.com/orgs/groupgets/repositories?type=all) to get you started with their products so you can quickly evaluate the Lepton and make sure it will work and what resolution/FOV is ideal: simply swap the different models in and out of the Molex socket. GroupGets also works with makers to get their prototypes to market, working with DigiKey for part sourcing (https://www.digikey.com/en/blog/digikey-partners-with-groupgets-to-help-startups-getmade) so if you have an idea and need a help making it to production check them out!If you need a high-quality thermal camera that is plug-and-play, easy to integrate and at a great cost, the Teledyne FLIR Lepton 3.1R Pocket-Sized Thermal Camera is hot hot HOT and in stock right now for immediate purchase from DigiKey (https://www.digikey.com/short/0zr8w59q). Order today, pick up an eval board too, and you can be measuring the world around you by tomorrow afternoon.See on DigiKey at https://www.digikey.com/short/0zr8w59qSee the manufacturer's video https://www.youtube.com/watch?v=9xsDuiq8eZc

This week's EYE ON NPI is the ideal component for your next power supply design, it's Nexperia's NID5100 Ideal Diodes (https://www.digikey.com/en/product-highlight/n/nexperia/nid5100-ideal-diodes) a simple design improvement to Schottky diodes or simple P-FET polarity protection. This small and low-cost component from Nexperia is their first 'ideal diode', and can be used in many low voltage power supply setups to reduce power loss and get you more product life from your batteryDiodes, who doesn't love them? (https://en.wikipedia.org/wiki/Diode) You put some P-doped Silicon next to N-doped Silicon (https://en.wikipedia.org/wiki/P%E2%80%93n_junction) and before you know it, you have accidentally semiconductored! Make them big enough and you can even solve global warming (https://en.wikipedia.org/wiki/Photovoltaics) We use diodes all the time, and they're particularly useful for power supplies since they make sure current only goes one way. We often use them in front of a DC jack, between the power input and the circuitry: this keep the voltage polarity positive with respect to ground, since most modern microelectronic components want between 3-24VDC. Or, as an OR: either battery or USB power are hot-swapped so that whichever gives the highest voltage will run the downstream electronics - see our Trinket M0 schematic for a simple example (https://learn.adafruit.com/adafruit-trinket-m0-circuitpython-arduino/downloads)When we first started electronics we'd use the classic 1N4001 (https://www.digikey.com/short/d8jn3f9v) - this low cost diode can handle high currents and about 1A continuous, with about 1-2V forward drop. When we did +12V power to an LM7805 (https://www.digikey.com/short/7vv3zc1d) this was fine, we have 5V to burn. Sometimes if we were feeling fancy we'd use a Schottky diode like the 1N5817 (https://www.digikey.com/short/8fntvnrv) which has about 0.7V drop, these are often used for boost or buck converters where you don't want to lose efficiency in your free-wheeling diode switch. But when using a 3.7V nominal voltage lipoly battery into a 3.3V regulator, we have to dial it down - even 0.7V is too high - so we'd often reach for a lower-drop Schottky like the Nexperia PMEG2010 (https://www.digikey.com/en/products/detail/nexperia-usa-inc/PMEG2010ER-115/2119861). We still use this part a lot, but we could do better with an Ideal Diode like the NID5100! (https://www.digikey.com/short/4td40hmh)Ideal diodes are as close as possible to the platonic ideal (https://en.wikipedia.org/wiki/Theory_of_forms#Ideal_state) of a diode as possible: Forward conduction only, with zero reverse conduction, and minimal voltage drop. Sometimes folks try to mimic this with a reversed P-FET and yes this will give minimal forward voltage drop for polarity protection (http://www.youtube.com/watch?v=IrB-FPcv1Dc), but it has 'infinite' reverse leakage instead of close-to-zero. The NID5100 is more complex, with additional circuitry for driving the P-FET. It can be used either as a polarity protection for a DC or battery input where there's risk of the voltage being inverted, or as an OR-ing voltage select. Compared to a Schottky, it can handle 1.5A continuous - most basic Schottky's are 1A - and with a forward voltage drop of only 50mV at 0.1A. The package size and price is also very comparable to a SOT323 diode, in an easy-to-place TSSOP6 and under 10 cents in reel quantity. We also like the extra pins like an Enable, so it can also act as an on/off switch, and a Status pin that lets you know when the diode is conducting: this can be used to detect which power supply is active in an OR setup.Does the Nexperia NID5100 (https://www.digikey.com/short/4td40hmh) sound like the ideal solution to reduce heat and power loss in your next product? Yes! And it's in stock right now at DigiKey for immediate shipment. Order today and you'll receive your components faster than a diode switching time, for integration into your BOM by tomorrow afternoon.

This week's EYE ON NPI is loud and proud - it's the Diodes Incorporated PAM8019E Class-D Audio Amplifier and Headphone Driver (https://www.digikey.com/en/product-highlight/d/diodes/pam8019e-class-d-audio-amplifiers), a combo audio amplifier that will add high quality analog audio output to your next design without breaking the bank.We've stocked and used the PAM series of audio amplifiers for over a decade, one of our best sellers is the PAM8302 (https://www.adafruit.com/product/2130) breakout which is a monophonic class D amp for basic projects. Things we like about it: its very inexpensive, it's rock solid, 3~5V power, hard to 'pop' and can drive 4~8 ohm output. But it's only one channel and we often get asked if we can stock a stereo Class D. Also, it's pretty common for us to get requests for headphone drivers. The PAM8019E (https://www.digikey.com/short/b3r00dw5) can do both, and has a lot of nice little details.First up, this is an analog in/out amplifier - no PDM or I2S or TDM. So this is good for either all-analog setups or when you have already converted your digital audio to 'line level', about 1Vpp. Since it's stereo out, there's also stereo input: don't worry about DC bias because you can couple in with 1uF and it will internally bias to half-VDD. Unlike the PAM8302 (https://www.digikey.com/en/products/detail/diodes-incorporated/PAM8302AASCR/4033281), this isn't differential input, reference is ground. You can use either the Headphone amp or Speaker amp, but not both: the selection is done with with a digital input pin which will do a smooth pop-free hand off.For the outputs, there's the stereo Class D outputs. These come as two tied-load bridges (https://en.wikipedia.org/wiki/Bridged_and_paralleled_amplifiers#Bridged_amplifier) which means you can just tie the two sides of each speaker to positive/negative without any capacitors. Class D is an efficient amplification architecture (https://en.wikipedia.org/wiki/Class-D_amplifier) and if done at a high enough frequency - in this case around 400KHz - the inductive load of the speaker acts as a filter so no separate RLC is required. For EMI purposes, the datasheet recommends a simple 100MHz 600ohm ferrite bead plus 1uF capacitor just to reduce the sharp square waves. For headphone, the chip uses a Class AB (https://en.wikipedia.org/wiki/Power_amplifier_classes#Class_AB). These are going to give cleaner output because there's no intermediate PWM stage: speakers tend not to be good enough to notice the hiss added from Class D, but headphones are much more sensitive. Also, at the ~50mW output we're talking about, there's not a lot of benefit to optimizing power. Since headphones are by design 'single ended', you will need 220uF caps on the output for high-pass filtering. Some modern audio amps have a 'floating' ground generated to sink the current for cap-less output but these tend to be more expensive and also wouldn't be compatible with line-level inputs.Some nice details we like to see in an amp, especially one this affordable: spread-spectrum so the high frequency PWM isn't centered on one spike, undervoltage-lockout, short-circuit on all outputs, pop-free, non-clip power limiting and separate not-in-line audio level selection. The last one is particularly nice because on the PAM8302 we have to put an analog rheostat in-line with the input pins to reduce the gain from 15x down to 1x or 2x. This would require a stereo pot, which can get scratchy and fail over time. On the PAM8019E (https://www.digikey.com/short/b3r00dw5), the gain is set with a DC voltage which means you can set it with a potentiometer or a DAC output, and you don't have to worry about jitter or scratchiness because there's hysteresis over 64 points.We've already ordered 10 pieces of the Diodes Inc PAM8019E (https://www.digikey.com/short/b3r00dw5) to design a breakout. DigiKey has tons in stock so we recommend you buy some too, at 34 cents a-piece, at reel quantity, it's hard to say no! They're available in 3x3mm or 4x4mm package sizes, both are QFN-20. Order today and you can be bumpin' and boppin' with either speakers or headphones by tomorrow. afternoon.

We sat down this morning to try and crank out a library for the VCNL4200 light/proximity sensor (https://www.digikey.com/en/products/detail/vishay-semiconductor-opto-division/VCNL4200/7394601) - these sorts of chips always have a trillion twiddly registers and are a bear to write. Phil recommended that Limor try out OpenAI's new ChatGPT Canvas (https://openai.com/index/introducing-canvas/). It's fast! And has very few errors. We like to go through each register one by one, add the typedefs and #defines, then the setter/getter functions, and finally the arduino ino 'sketch' to actually test and verify. However, with three files - header, cpp, and ino - canvas can get really confused about which file we're editing and what it's called. Our request! We would love it if there were tabs for 'fixed' file names, and then clicking on the tab set the context for the code we're collaborating on.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#openai #chatgpt #canvas

The TM1814 LEDs we've been looking at this week require an inverted NeoPixel-like signal. While it's not too hard to make a custom library to deal with the prefix bytes, the inversion is a little annoying since you'd have to rewrite a lot of assembly. So, for our level shifter board we designed, let's also add an inverter: It will use 5V power and logic, and we'd like a small SC70-5 package so we can keep the board as compact as possible.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is having Too Much Fun - it's the ams OSRAM TMF8806 Single-Zone direct Time of Flight sensor (https://www.digikey.com/en/product-highlight/a/ams/tmf8806-single-zone-tof) the latest in ams' series of ToF sensors. This sensor may seem like "YAToF" but there's a few things that caught our eye. One is the excellent pricing, about $2 in quantity. Another is the simplicity of function: unlike many ToF sensors, there isn't a massive firmware stack required to load on each boot. Instead, the default firmware is in ROM for a lightweight interface.We've stocked ToF sensors (https://www.adafruit.com/search?q=tof) for quite a while - mostly the ST VL series. These sensors have developed quite a bit over the years, starting with the 100mm-range VL6180 (https://www.adafruit.com/product/3316) and continuing onto multi-grid devices that we've covered on previous EYE ON NPI's (https://www.youtube.com/watch?v=3PocFz427NE). The way these work is by blasting laser pulses out of a VCSEL (https://en.wikipedia.org/wiki/Vertical-cavity_surface-emitting_laser) which then bounces off of the target and the 'time of flight' is measured in the pF range to give accuracy and range. Easy to describe, but non-trivial to implement...the light doesn't bounce off perfectly, and a lot of individualy measurements need to be taken and then averaged - this is called the histogram. The histogram data is filtered in software to toss outliers and double-bounces, to get the 'true' calibrated distance. And it has to do this dozens of times a second. The complexity of the algorithm is what gives each product its accuracy, precision, repeatability and range - so its no surprise that its running on an in-package microcontroller. However, as the sensors have gotten more advanced, the firmware process has also gotten complex: for many ToF sensors you have to 'load' the firmware algorithm on boot (https://github.com/STMicroelectronics/stm32-vl53l5cx/blob/main/modules/vl53l5cx_buffers.h#L33) and even if you don't, its a non-trivial port to other platform.That's what caught our eye for the ams OSRAM TMF8806 (https://www.digikey.com/short/f9v8w20d), the description specifies "No FW download is required to operate this device, saving host MCU memory space, reducing startup time, and saving overall system power by enabling customers to quickly start the device and make measurements in a few milliseconds". The interface is trivial, they even provide the I2C commands required to boot, load firmware, and perform a reading, its about a dozen commands. For hardware, it's also a nice and simple integration - with a small OLGA package, I2C communication, and 1.8V or 3.3V logic level.One thing to watch for, the sensor comes with 3 'modes' - short, medium and long range. Minimum range for all of these is 10mm, the max is 200, 2500 or 5000mm. And,while the sensor can do 5000mm, it requires pretty specific calibration and lighting. The default range is 2500 and we recommend sticking to that if you can because then you get the benefit of built-in configuration and calibration for speed/simplicity.To get started fast, ams OSRAM supplies multiple drivers for Arduino or other C microcontrollers (https://github.com/ams-OSRAM/tmf8806_driver_arduino), generic Python (https://github.com/ams-OSRAM/tmf8806_driver_python) and Linux kernel (https://github.com/ams-OSRAM/tmf8806_driver_linux). You can also grab an eval board in 'shield' format that has a microcontroller for plug-and play usage (https://www.digikey.com/en/products/detail/ams-osram-usa-inc/TMF8806-EVM-EB-SHIELD/24768739)Add low power, super fast ToF sensing to your next design with the ams OSRAM TMF8806 Single-Zone direct Time of Flight sensor (https://www.digikey.com/short/f9v8w20d), in stock for immediate shipment from DigiKey! Order today and it will ship to you at pico-second speed, so that you can be integrating it by tomorrow morning.

"Hi, I'm looking for the thinnest possible coax wire and found that you used to have this listed at 1.2mm diameter. All the other RG-174 cable I've found online is 2.8mm diameter. Just curious where you found it and if you would ever stock it again. Or any other info that would help me search for this 1.2mm version."This week, we received a request for how to find ultra-thin RG-174 cable, such as the one we used to stock (https://www.adafruit.com/product/2059). Note that this isn't stranded or solid core wire; it's a 2-conductor coax, as thin as 16 AWG wire. We no longer carry this cabling, but DigiKey does!

This week's EYE ON NPI is Gon' Give It To Ya (https://www.youtube.com/watch?v=fGx6K90TmCI), it's the MaxLinear half duplex RS-485 transceivers (https://www.digikey.com/en/product-highlight/m/maxlinear/rs485-422-serial-transceiver) an easy way to convert your every day UART serial connection to a RS-485 or RS-422 data link layer (https://en.wikipedia.org/wiki/Data_link_layer). We've seen RS-485 most often in DMX512 lighting networks (https://en.wikipedia.org/wiki/DMX512), where there are up to 512 lights/devices connected up to a control board 'universe'. Each one is individually settable. While these could have used CAN bus, or Ethernet, DMX ended up using RS-485 for simplicity and low cost. It's super easy and inexpensive to convert between UART and RS-485 using a MaxLinear chip because the encoded data is the same as 8N1 serial.Each line of RS-485 consists of a differential signal pair, A + B, where A is inverted from B and B's logic level is the bit being sent. This means it can go farther and more reliably than RS-232 (https://en.wikipedia.org/wiki/RS-232) which is single-ended and just has wide voltage swings. However, instead of having ground, RX and TX for connection between two data ports - DCE and DTE - RS-485 cables as used in a DMX setup have the A and B wires plus ground. This means RS-485 going to survive signal degradation better than RS-232 but the downside is its uni-directional. That's fine for lighting rigs because you just want to tell the light "turn blue" or fog machine "on". RS-485 is also driven quite fast, the DMX standardizes on 250kbps comfortably, whereas RS-232 does best at 115.2kbps or less.If you really want, it is possible to convert the line into a bi-directional setup as long as the transmitter knows when to expect signal from a remote device. Simply sent the Driver Output Enable pin of the MxL8321x (https://www.digikey.com/short/dm7zp1hf) low to tri-state the output driver buffer, then set Receiver Output Enable line low, this will swap the device from being a transmitter to a receiver. The light on the other side will do the opposite, setting both pins high to turn into a transmitter. It can then send signal back down the line. Technically this is the difference between RS-485 and RS-422 (https://en.wikipedia.org/wiki/RS-422), which is really just the differential-ized RS-232 part without output/input enable and thus does not have the ability to change 'direction'. For RS-422 you'll probably want two MxL8321x's (https://www.digikey.com/short/dm7zp1hf), one for each direction.While used often for DMX512, you don't have to use the DMX protocol with your MxL8321x RS-485 converters: after all it's just a new physical layer for UART serial, so if you have any design that already uses serial: GPS, MIDI, microcontroller communication, radio modules, you can pop these in between for no-fuss extension from a few inches to many meters, up to 500kbps. The MxL8321x uses 3.3v or 5V power/logic so its easy to integrate into any existing design. The family also comes in a few package sizes and speed variants, from the MxL83211's (https://www.digikey.com/short/55bp41c9) 250kbps to the MxL83214's 50Mbps (https://www.digikey.com/short/zrb42hdh). Pick the slowest one you can use to get the best line drive strength to reduce EMI and reflections. You'll also need to set up a terminator (https://www.ti.com/lit/an/snla044b/snla044b.pdf) on the end of the transmission line.If you're looking to add RS-485 or RS-422 support to your next design, MaxLinear is here to Give You What You Really Want (https://www.youtube.com/watch?v=0MdAbsd0HmI) with their wide range of half duplex RS-485 transceivers. And best of all, DigiKey has them all in stock for instant shipment to your door. Order today and you'll have your MxL8321x in hand by tomorrow morning for instant integration.

The RP2350 Feather has an FPC output connector for accessing the HSTX - high-speed transmission - peripheral. This lets us drive DVI displays really easily! Today, we got the prototype PCBs for our HSTX to DVI adapter board; after connecting up a 22-pin FPC cable, we can test out DVI driving via CircuitPython. With HSTX, we don't need to overclock or use PIO, and there's a lot more RAM on the RP2350, so we can easily do 320x240 with 16-bit color and have plenty of SRAM left over. It would be neat if we could do DVI from the PSRAM as a framebuffer at some point for really big displays!#adafruit #circuitpython #rp2350Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI will make you Stop! In the Naaaaaaaaaaame of Love (https://www.youtube.com/watch?v=9JiS02O4fEk) but will never break your heart - it's E-Switch's E200 Series E-Stop Pushbutton Switches (https://www.digikey.com/en/product-highlight/e/e-switch/e200-series-e-stop-pushbutton-switches). These are two small emergency stop switches that are durable, ergonomic, safe and easy to use! Both have immediate "slam to stop" and "twist to re-start" functionality. One has a classic mushroom-domed top and the other is a longer grippy wheel that comes with a optional center illumination by neon bulb or LED.Just this week we were talking with someone working in safety design and recommended The Design of Everyday Things (https://jnd.org/books/the-design-of-everyday-things-revised-and-expanded-edition/) a book that covers how to design 'obvious' things in the real world - like how doors pull when entering and push to exit a building, so that folks trying to escape a building in a panic don't get trapped. A lot of the design decisions have been learned by hard lessons: people getting injured or dying... that's why we have things like building codes and engineering certifications such as those for medical devices (http://sunnyday.mit.edu/papers/therac.pdf). Even when we do our best to design safety margins, redundancies and interlocks, there's always the chance that something will go wrong. Especially when designing robots, machinery, lasers, or some other "Machine that does not know the difference between metal and flesh, nor does it care" (https://www.reddit.com/r/Machinists/comments/sg9wct/i_made_a_sticker_for_the_lathe/)That's where you definitely want to add in an emergency stop switch, also known as a kill switch. Wire this up in series with your main power input and no matter what happens with your firmware or interlock or other secondary safety features, you will cut the power instantly. The brilliance in this design is that you push or slam down on it to open the contacts but then you need to twist to reconnect. This means folks can't accidentally turn it on again by pressing again, there's no chance of it bouncing closed, and you can immediately verify the state by pressing it again.The E-Switch's E200 Series E-Stop Pushbutton Switches (https://www.digikey.com/en/product-highlight/e/e-switch/e200-series-e-stop-pushbutton-switches) are both rated for 250VAC 5A, 125VAC 8A or 24DC 6A with IP65 dust-tight (https://en.wikipedia.org/wiki/IP_code). Simply drill a 16mm hole in your enclosure to mount. The contacts are shrouded to minimize risk of cross-contact, use 0.11"/2.8mm spade quick contacts (https://www.digikey.com/en/products/detail/te-connectivity-amp-connectors/2-520083-2/289211) to connect.Whichever variant you choose, you can add a stylish kill switch to your next design from a trusted switch manufacturer that will keep your users and products safe from each other. And best of all, DigiKey has both E-Switch E200's (https://www.digikey.com/short/5tvqhj4b) in stock right now for immediate shipment! Order today and you'll be E-Stopping by tomorrow afternoon.And check out the manufacturer's video at https://www.youtube.com/watch?v=6TY-6tbsB0E

We've got the DS2484 in stock, that our I2C-to-1Wire converter board https://www.adafruit.com/product/5976 and we also now have a prototype breakout for the DS2842S-800 which has 8 selectable channels. on one hand, you can always have multiple 1-wire sensors on a single 1-wire bus, but you have to deal with ROM addressing to know which is measuring what. by having 8 separate channels you can be more sure about what each sensor is sensing, and it was pretty easy to add support - just one more function for adjusting the active channel.The DS2842-800, with eight selectable channels, simplifies 1-wire sensor management compared to the DS2484.

This week's EYE ON NPI has some Nice Freakin' Chips - it's STMicroelectronics' NFC Smart Tag Set, (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/st25-tag-bag-ut1-nfc-tag-set) with a cornucopia of labels, stickers, cards and tags that feature ST's Near Field Communication (NFC) chipsets, each with a matching antenna. This 18-piece kit is a great way to evaluate the different materials that NFC tags can be embedded in as well as verify that your NFC reader chipset works at the desired distances. NFC is built on top of the 'RFID' tags you're probably familiar with, unlike read-only RFID tags, NFC has bi-directional communication which means you can write values to the tags which makes them universal. For example, instead of having to manage a separate database that maps the 64-bit RFID value to a product SKU, the SKU itself can be written directly into the non-volatile memory on chip. Stuff like urls, timestamps, account balances, and sensor logs can go straight into the chip for anyone to access - or only for users with the correct password-unlock-code.NFC tags, stickers and cards are an upgrade from iButtons (https://www.analog.com/en/product-category/ibutton-products.html) -- less clunky, do not need to make electrical contact, magnetic stripe cards (https://en.wikipedia.org/wiki/Digital_card) -- can hold more information, are less flakey, don't delaminate or demagnetize, or barcodes (https://en.wikipedia.org/wiki/Barcode) -- need good light for optical reading, can be sluggish, very limited amount of data. Since NFC chips have bi-directional communication, plus built in encryption and writable memory, without any battery, they need to harvest energy from RF waves. That means that the the antenna is used for both data and energy and needs to be both tuned to the chip's internal capacitance as well as maximized in order to get the most E field possible (https://www.st.com/resource/en/application_note/an2866-how-to-design-a-1356-mhz-customized-antenna-for-st25-nfc--rfid-tags-stmicroelectronics.pdf). So, in general, the bigger the antenna the 'better' performance you'll get: shorter taps, less finicky alignment, and farther functionality. However - of course, you've got a bigger surface area for the tag. Here's the sizes that come in the ST NFC Smart Tag Set (https://www.digikey.com/short/rf5ddb3c):Three ST25TV02KC (https://www.digikey.com/en/products/detail/stmicroelectronics/ST25TV02KC-TFH3/18085938), 23 pF, tamper enabled label, 35 mm diameterThree ST25TN01K (https://www.digikey.com/en/products/detail/stmicroelectronics/ST25TN01K-AFH5/15775849), 50 pF, smart label, 30 mm diameterThree ST25TV02KC (https://www.digikey.com/en/products/detail/stmicroelectronics/ST25TV02KC-TFH3/18085938), 99 pF, smart label, 17 mm diameterThree ST25TV02KC (https://www.digikey.com/en/products/detail/stmicroelectronics/ST25TV02KC-TFH3/18085938), 23 pF, smart label, 50 mm x 50 mmThree ST25TV02KC (https://www.digikey.com/en/products/detail/stmicroelectronics/ST25TV02KC-TFH3/18085938), 23 pF, on-metal tag, 30 mm x 30 mmOne ST25TV02KC (https://www.digikey.com/en/products/detail/stmicroelectronics/ST25TV02KC-TFH3/18085938), 23 pF, button tag, 22 mm diameterOne ST25TN01K (https://www.digikey.com/en/products/detail/stmicroelectronics/ST25TN01K-AFH5/15775849), 50 pF, card, 85 mm x 54 mmOne ST25TV02KC (https://www.digikey.com/en/products/detail/stmicroelectronics/ST25TV02KC-TFH3/18085938), 23 pF, NFC field detector with LED indicator, 85 mm x 54 mmA nifty feature we saw in the datasheet for the ST25 (https://www.st.com/en/nfc/st25tv-series-nfc-tags.html) is the "tamper detection" capability. Normally to make sure that the end-recipient can detect whether a box was opened in transit is to use a tamper detection sticker that tears when removed. Instead of needing two stickers, or even just relying on a human to properly detect the tampering, the ST25 chips have two extra contacts that can connect to a thin wire switch. When the sticker is moved the thin wire is broken and the chip will detect it. Since we can use encryption/authentication on the ST25, the tamper sticker tag can't be replaced. And, when using a digital logging system, it will automatically record the tamper without a person being able to fudge the reading.If you want to get started with integrating STMicroelectronics' ST25T NFC chips (https://www.digikey.com/en/products/filter/rfid-rf-access-monitoring-ics/880?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANogDsAnGKyALqEAOALlCCAC%20woA) or tags into your product authentication/identification, access or inventory management, data logging, or asset tracking, then the NFC Smart Tag Set (https://www.digikey.com/short/rf5ddb3c) is a quick and easy way to get a wide range of stickers and cards to try out. Order today and DigiKey will pick, pack and post your order you'll have these tags in hand by tomorrow afternoon.

We think this is a great proof-of-concept that can help prevent failed prints. This project uses an IR Optical Sensor that can detect whenever an object passes by the sensor. The breakout is mounted to a 3D printed bracket right above the 3D printer!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitShop for parts to build your own DIY projects http://adafru.it/3dprinting3D Printing Projects Playlist:https://www.youtube.com/playlist?list=PLjF7R1fz_OOWD2dJNRIN46uhMCWvNOlbG3D Hangout Show Playlist:https://www.youtube.com/playlist?list=PLjF7R1fz_OOVgpmWevin2slopw_A3-A8YLayer by Layer CAD Tutorials Playlist:https://www.youtube.com/playlist?list=PLjF7R1fz_OOVsMp6nKnpjsXSQ45nxfORbTimelapse Tuesday Playlist:https://www.youtube.com/playlist?list=PLjF7R1fz_OOVagy3CktXsAAs4b153xpp_Connect with Noe and Pedro on Social Media:Noe's Twitter / Instagram: @eckenPedro's Twitter / Instagram: @videopixil-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.com/?utm_source=youtube&utm_medium=videodescrip&utm_campaign=3dprintingSubscribe to Adafruit on YouTube: http://adafru.it/subscribeAdafruit Monthly Deals & FREE Specialshttps://www.adafruit.com/free?utm_source=youtube&utm_medium=videodescrip&utm_campaign=3dprintingJoin our weekly Show & Tell on G+ Hangouts On Air: http://adafru.it/showtellWatch our latest project videos: http://adafru.it/latest?utm_source=youtube&utm_medium=videodescrip&utm_campaign=3dprinting3DThursday Posts: https://blog.adafruit.com/category/3d-printing?utm_source=youtube&utm_medium=videodescrip&utm_campaign=3dprintingNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/?utm_source=youtube&utm_medium=videodescrip&utm_campaign=3dprintingMusic by Bartlebeats https://soundcloud.com/adafruit-----------------------------------------

This weekend we designed a simple "Trinkey" board for the ESP32-C6 (https://www.digikey.com/short/c7f7qzm8) and we thought it would be kinda cute if it came in a clear enclosure that would protect the components. We then remembered that you can get some 'USB key' enclosures ready to go from DigiKey, at very good prices!

This week's EYE ON NPI looks miiiiiighty familiar with those of us who love our colorful lights, it's Würth Elektronik's RGB WL-ICLED Integrated Controller Within LED (https://www.digikey.com/en/product-highlight/w/wurth-electronics/wl-icled-integrated-controller-within-led). WE's take on the 'smart LED' has taken over the electronics industry over the past 15 years. These ubiquitous LEDs can save you time, pins, and cost by simplifying the addition of up to a couple-dozen colorful LEDs, especially when the PCB size is at a premium.Back in my day, if you wanted to add a lot of colorful LEDs to a design, you'd have to use a dedicated LED driver chip. That is, unless your microcontroller had tons of pins, and 10mA drive current - and even then there's a total current-draw limit for the chip package. We still stock some breakouts for these like the TLC5947 (https://www.adafruit.com/product/1429) a 'chainable' SPI board that could drive 8 RGB LEDs and PWM them all for you, often with a set-able constant-current. There's still need for chips like this, but they're often kinda large, and they're not free, so using them was not a light matter. Then came the first - or close to the first - low cost chainable LED driver: the LPD8806 (https://www.adafruit.com/product/306). We wrote a library for this chip in 2011 (https://github.com/adafruit/LPD8806/commits/master/?after=1951478c2c2a8317feab9997cdfddba3728a245a+69), the way this chip worked is it could control two RGB LEDs per, with all PWM handled internally and you only needed 2 pins! This was inexpensive and worked great, but the chips were still a bit large, 14-SOICs. They were superseded by the WS2811 (https://www.adafruit.com/product/1060) which came up with using a Manchester encoding (https://en.wikipedia.org/wiki/Manchester_code) for transport over a single line. These used even less space, and only a single pin, with an SOIC-8 package. However, the real ingenuity is when folks realized they could put the chip INSIDE the LED: and thus was born what we call "NeoPixel" (https://www.digikey.com/en/products/result?s=N4IgTCBcDaIHYFMD2AHAlgDwQGxAXQF8g) a fully chainable smart LED that only uses one pin and no external components.Now all's been right in the world, with dozens of different shapes, configurations and sizes of 'WS2812-compatible' LEDs. But there was one thing missing: a reliable source of smart LEDs. And we should know because we use a lot of these chips: and we try to warn folks that low cost LEDs have differing LED color and brightnesses, are hard to solder and rework, and suffer high failure rates in the field. Worst of all, when one fails all the ones down the line also fail! Until today you just had to cross your fingers and hope that the reel you got was from a 'good batch'.That's why we were excited to see Würth Elektronik's RGB WL-ICLED in DigiKey's NPI list, because WE is known for high quality, reliable products. Unlike most NeoPixel compatibles, this datasheet specifies the LED brightnesses and spectra. It also has RoHS, REACh and Halogen compliance. Finally, you know you'll be getting consistent quality, where each LED solders just as well as last week's or last year's batch. The WL-ICLEDs are available in 4 sizes, including the common 5x5mm and 2x2mm. Würth Elektronik also designed a cool FeatherWing (https://github.com/WurthElektronik/FeatherWings/tree/main/ICLEDFeatherWing) with hundreds of the 2x2mm ICLEDs to demo how to display animations, text, and graphics. (https://www.youtube.com/watch?v=_tCo7FSO1Gk)If you want a NeoPixel compatible LED, with trace-ability, high reliability and known functionality check out Würth Elektronik's RGB WL-ICLED (https://www.digikey.com/en/product-highlight/w/wurth-electronics/wl-icled-integrated-controller-within-led) available right now at DigiKey! Order today and you'll get your ready-to-assemble rainbows by tomorrow afternoon.

This week we're working a bit with BlitzCityDIY on a project to replace the innards of a IKEA VINDRIKTING PM2.5 sensor (https://learn.adafruit.com/ikea-vindriktning-hack-with-qt-py-esp32-s3-and-adafruit-io) with our own board featuring an ESP32-S2 (https://www.digikey.com/en/products/detail/espressif-systems/ESP32-S2-MINI-2-N4R2/16591895) so that it can be IoTified with ease.Ideally we will reuse the same enclosure - so we have to have matching connectors! The challenging one is the the vertical USB C, because we have very little clearance, so we need to find a near-exact match that doesn't have excess plastic. Otherwise, it won't fit into the case properly. Let's visit DigiKey to find a good match.See the chosen parts on DigiKey here https://www.digikey.com/short/z7b30q95Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is an "easy pick" - it's Aven Tools' E-Z Pik Tweezer sets (https://www.digikey.com/en/product-highlight/a/aven-tools/e-z-pik-tweezer-sets), available in lovely epoxy color coatings that let you quickly grab the exact one you need when doing rework, repair, or assembly. Having the right tool for the job will make your life a lot easier, and we're constantly poking and prodding our fine-pitch assemblies. We're also a teensy-bit clumsy, so we're sometimes dropping or denting our tweezers. That's why it's good to have a variety at hand: if you're using tweezers for 4+ hours a day, you will quickly notice the difference between your 'basic soldering kit tweezers' and the good stuff!This NPI comes at a good time, because DigiKey is currently running the "2024 PCB Business Card Challenge" with hackaday.com (https://hackaday.com/2024/06/19/2024-business-card-challenge-pcb-business-cards-for-everybody/) and a lot of the entries have SMT components to keep the circuitry small and thin. And even though I personally don't have an entry - I've seen my designs go from using 1206 (https://learn.adafruit.com/minty-mp3/make) to 0805 back when we had the MDC Luna Pick and Place (https://www.ladyada.net/wiki/mdcpickandplace) to now mostly 0603's thanks to our Samsung SM482 (https://blog.adafruit.com/2013/04/03/samsung-techwin-smt-sm482-adafruits-new-pick-and-place-machine-has-arrived/) with some dabbling in 0402's for smaller-packed designs. If you're reworking those small 0402s, a good set of tweezers is a must!There's two E-Z Pik Tweezer kits available, one with 6 pieces and one with 9, we splurged for the bigger kit (https://www.digikey.com/short/j9z4w2pn). Both are made with the same quality and features:FeaturesColor-coded tweezer set allows operators to quickly identify the exact tweezer needed for a task with just a glanceAvailable in 6- and 9-piece sets that contain popular tweezer styles packaged in a convenient storage pouchMade from anti-acid and anti-magnetic 304 series stainless steel, providing durability and corrosion resistanceThe tweezer tips are hand-finished by expert artisans for precise alignmentThe durable epoxy coating is designed for demanding tasksWe particularly like the anti-magnetic because one of our tweezers got magnetized and now we can't use it with 0603's and smaller because the parts stick to the tip. Both Aven Tools E-Z Pik Tweezer sets (https://www.digikey.com/en/product-highlight/a/aven-tools/e-z-pik-tweezer-sets) come with a nice roll-up storage bag and are in stock for immediate shipment from DigiKey - order today and you'll be tweezin' by tomorrow afternoon.

Back in the old days, before USB, we had to use RS-232 to communicate with computers. One of our first designs was the ATmex (https://www.ladyada.net/techproj/Atmex/index.html), a microcontroller board with a built in bootloader! We used the MAX232 (https://www.digikey.com/en/products/detail/texas-instruments/MAX232DR/555684) to convert 5V serial to +-10V RS-232. These days, with USB-Serial converter chips like the FT232 or CP2102, you'll still see remnants of that past, such as DTR and RTS pins. When working with retro or industrial equipment, you may still find RS-232 DE-9 connectors. Let's take a look at some 3.3V-friendly transceivers, and find one that can do the full 5/3 pin-complete DE-9 connection set.See the chosen parts on DigiKey here https://www.digikey.com/short/218mnb89Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI gyres and gimbels through the wave. It's the latest LSM6DS 6-axis accelerometer + gyroscope IMU from STMicroelectronics. (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/lsm6dsv32x-6-axis-imu). This latest update to the LSM6DS line is packed with features such as I3C, step counter, Qvar electrostatic sensing, finite state machine, AI 'learning core' and embedded sensor fusion so not only are you getting an IMU but a full user interface and sensor management hub.We've been stocking and using the LSM6DS series for many years: starting with the LSM6DS33 (https://www.adafruit.com/product/4480) a great low cost 6-DoF to the LSM6DS3C-TR replacement (https://www.adafruit.com/product/4503) to the fancy-pants LSM6DSOX (https://www.adafruit.com/product/4438). These are pin-compatible, and nearly-firmware-compatible sensors that are compact, sensitive and precise. In particular, what we look for in a good IMU chip is the gyro offset and drift. When making an inertial measurement unit (IMU) especially one used for orientation calculations, the quality of the gyroscope has a big impact on the jitter/speed/drift. (https://learn.adafruit.com/adafruit-sensorlab-gyroscope-calibration/comparing-gyroscopes) Accelerometers are pretty good quality these days, we've figured out how to make them decades ago. And magnetometers are not as important - they don't update often and are used for orientation correction. Gyro's have the most error possibilities. In general, the more you pay, and the newer the sensor, the better performance you'll get in the form of low offset and low drift. The LSM6DSV32X has similar gyro/accel characteristics from the LSM6DSOX and ISM330DHCX - although we'll note the min/max is not documented, just the typical values. And there's some ISM330 parameters such as Angular random walk and Bias Instability, that are not specified.That said, as long as you're good on calibration, and the specs are within your limits, the embedded functions are where the LSM6DSV32X really shines. Like many ST accelerometers, there's a built in pedometer (https://github.com/adafruit/Adafruit_LSM6DS/blob/master/examples/adafruit_lsm6ds_pedometer/adafruit_lsm6ds_pedometer.ino) as well as a tilt / motion sensor. The first is good for step counting, the second lets the sensor go into a low power state and set an interrupt pin when the device is moved or tilted to wake up the rest of the UI. The more advanced functions include a 'machine learning core' (https://www.st.com/resource/en/application_note/an5804-lsm6dsv16x-machine-learning-core-stmicroelectronics.pdf). We use that term lightly because it's more like a 'decision tree' where you can set up test conditionals post-normalization/filtering to classify simple motion states such as "running", "sitting" "lying down". These won't be as flexible as a true machine-learning algorithm that uses sample data to create a model, but you also don't have to spend any power or computation.Another advanced feature ST has been adding to many of their chips is Qvar electric charge variation detection sensing. This ultra-sensitive capacitance-like sensing can be used for human presence and motion detection, as well as touch/proximity detection. The eval board comes with a few Qvar plates for trying it as a slide or touch sensor as well as a 'radar' like proximity detector. (https://www.digikey.com/en/products/detail/stmicroelectronics/STEVAL-MKI240KA/22522578) This could be nice to use if you've got a microcontroller that does not have touch sensing peripherals, since now you don't need a separate chip.The new feature we're most interested in is the "Sensor fusion low power" block - which can output a game rotation vector in quaternions, that gives the chip attitude (https://en.wikipedia.org/wiki/Orientation_(geometry)) direct from the sensor, without needing to continuously read/buffer/analyze the 6-DoF data. We'll note that there's no magnetometer, so it won't have 'absolute' orientation against the earth, but for many use cases a rough orientation - especially one that is self-driving and low power - will suffice. We'll note that for getting started, the LSM6DSV16X library on GitHub has examples for this and the other embedded features. (https://github.com/stm32duino/LSM6DSV16X)If you want to try out the new ST LSM6DSV32X 6-Axis IMU with 32 g Accelerometer (https://www.digikey.com/short/bhq3bwhf) or it's smaller sibling, the LSM6DSV16X (https://www.digikey.com/short/524744wt) both are available and in stock from DigiKey right now. Pick the 16g version if you're doing every-day motion sensing and 32g for sports / high speed activities. The eval board is also available and great if you want to start fast and also check out the new Qvar sensor feature (https://www.digikey.com/en/products/detail/stmicroelectronics/STEVAL-MKI240KA/22522578). Order today and you will be ready to integrate the latest IMU into your design by tomorrow afternoon.

This week we had the idea of making a breakout for IrDA data transfer: this is an older infrared bi-directional protocol that can mimics UART-like behavior with RX and TX running at 115.2Kbps. It could be useful for projects where you want to make a link between two boards but don't want the expect, complexity or overhead over RF. Simply transmit and receive whenever the two are within about a meter of distance. This used to be used for simple data transfer between computers, handhelds, or watches. They've phased out of popularity in the last couple decades... can we still get IrDA transceivers at DigiKey?

This week's EYE ON NPI is teamwork makin' the dream work - a collaboration between our favorite module makers Raytac (https://www.digikey.com/en/supplier-centers/raytac) and our favorite Bluetooth Low Energy designers, Nordic Semiconductor (https://www.digikey.com/en/supplier-centers/nordic-semiconductor). Together they've created what we think is the best nRF52840 module, the Raytac MDBT50Q-1MV2 (https://www.digikey.com/short/t8hvw1bt). Historically you've had to pick this up direct from Raytac, but now it's stocked by DigiKey which is excellent news for anyone who wants to integrate the powerful nRF52840 with little fuss.The Nordic Semiconductor nRF52840 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52840-QIAA-R/7725407) is not a new chip, we've been selling the Feather nRF52840 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4062/9843410) since 2019 and the chip itself was announced in mid 2017 (https://www.nordicsemi.com/Nordic-news/2017/05/Nordic-Semiconductor-introduces-latest-nRF52-Series-SoC). It builds on the popular nRF52832 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52832-QFAB-R/6051565), a chip with an Arm Cortex M4-F / 512K Flash / 64K SRAM, but with a ton more memory: the '840 has 1MB Flash and 256K SRAM. It also comes with native USB device support, which is new to the nRF series but makes product design easier because DFU and computer-interfacing doesn't require a second chip. The only challenge is that the nRF52840 itself is in a funky QFN package with pads underneath, and multiple rows, which requires either very fine traces, 4-layer boards, plugged vias, or a combination, in order to get to the 'inner' traces. Also, you have to get your antenna tuning right - even though the nRF is very forgiving, it's still extra effort!That's why at Adafruit we have been using Raytac's MDBT50Q-1MV2 Module (https://www.digikey.com/short/t8hvw1bt) for years, in our Feather nRF52840 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4062/9843410), ItsyBitsy nRF52840 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4481/11497502) and CLUE board (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4500/11594501). We like that it pick-and-places cleanly and easily on 2-layer PCBs with 8/8 rule DRC, comes with certifications, and has a couple different built-in antenna options, all tuned and ready.In particular, if you want a larger and/or external antenna check out the MDBT50Q-U1MV2 (https://www.digikey.com/en/products/detail/raytac/MDBT50Q-U1MV2/13968055) but we like the chip-antenna version the most. Either way, the module footprint is much easier to work with - you still have pads underneath but they're large, and you can easily fit vias in the unused spots. Just make sure you keep ground clearance around the antenna if you're using an on-module version. If you need tips on schematic and layout, just use our open source hardware design files to guide you - or check Nordic's devZone (https://devzone.nordicsemi.com/).If you've wanted to use the Nordic Semiconductor nRF52840 chip (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52840-QIAA-R/7725407) for your ultra low-power Bluetooth LE products, but have hesitated due to the effort of integrating the QFN chip, we can't recommend the Raytac MDBT50Q-1MV2 module (https://www.digikey.com/short/t8hvw1bt) enough! And now that it's for sale through DigiKey, you can pick up some at a great price. Order today and you can BLE-ify your next design by tomorrow afternoon.
This week's EYE ON NPI is more like an "EYE ON Ladyada's Desk" because while the ESP32-C6 has not yet been featured by DigiKey on their New Products Page (https://digikey.com/new) we're starting to spend a little time checking out this new Espressif chip - the ESP32-C6 series - and the ready-to-use modules available from DigiKey, such as the ESP32-C6 WROOM (https://www.digikey.com/short/8vj302rf). We use the Espressif family of chips (https://www.digikey.com/en/supplier-centers/espressif-systems) in tons of our designs: they're inexpensive, powerful, have excellent low-power sleep modes, and all come with fast and secure WiFi functionality, so they make for excellent IoT devices. Starting with the ESP32 in 2016, a follow-up to their 'accidental microcontroller' the ESP8266, Espressif has focused on Tensilica-based microcontrollers with built in WiFi and/or Bluetooth radio. By combining the silicon for radio and processor, they've been able to come in at disruptively-low pricing (https://en.wikipedia.org/wiki/Disruptive_innovation) - with chips ranging from $1-$3 and modules from $2-$6.Over the years they've branched out to include improved BLE, native USB, and many other peripherals like CAN and TFTs. They've also dabbled in RISC-V, adding a co-processor to the ESP-Sx series and finally going 'full RISC-V' in the ESP-Cx series. Now, with the C6, they're adding a new protocol to the mix: in addition to updating to WiFi 6 and BLE 5, the C6 also can talk 2.4GHz 802.15.4 which means it can communicate with Zigbee devices (https://en.wikipedia.org/wiki/Zigbee) including Thread and... Matter (https://en.wikipedia.org/wiki/Matter_(standard)) an open-source connectivity standard for smart home and Internet of Things devices from the Connectivity Standards Alliance (https://csa-iot.org/) formally the ZigBee Alliance.Matter is, hopefully, not just the latest, but the last attempt at creating a unified standard for home/business/industrial IoT and automation. It is a higher level protocol that runs on top of WiFi, BLE, or Thread - Thread being a replacement for Zigbee that also runs on 802.15.4 radios. That means that if you want to create a Matter device, you can use any of the three transports (https://learn.adafruit.com/alltheiot-transports) supported by the ESP32-C6: WiFi is medium range, medium cost, high power, medium complexity and high data rate: once you set up the access point, and as long as it's plugged into the wall, it tends to work very well. BLE is lower range, low cost, low power and medium complexity since you still need to pair to another device. Thread/ZigBee is medium range, low power, low cost, and high complexity since you need a gateway to use. As of this post/video, the Matter API for Espressif chips is only available through the ESP IDF SDK (https://github.com/espressif/esp-matter), and not in Arduino yet, although there is an open issue being worked on (https://github.com/espressif/arduino-esp32/issues/7432). However, if you aren't up for using the ESP-IDF for programming, you can check out ZeroCode (https://zerocode.espressif.com/) Espressif in-browser code generation, compilation and uploading system. At this time only '2-chip' setups are available for code generation, the 'bare' ESP32-C6 support is coming soon, but we tried out the IoT ExpressLink configs (https://www.espressif.com/en/solutions/device-connectivity/esp-aws-iot-expresslink) which have UART commands for setting up and tearing down the Matter device. After filtering for ExpressLink, we selected the C6 Mini module we have on our Feather prototype. A schematic is generated to show how the module will need to be wired for the UART access. Then you can program it directly in the browser. The unique Matter identifier is turned into a QR code: you can scan this with your mobile phone to add the device to your home's Matter-hub. Finally - check out the AT command reference (https://docs.aws.amazon.com/pdfs/iot-expresslink/latest/gettingstartedguide/expresslink-gsg.pdf) for how to start the Matter subsystem and send/receive data.As Thread/Matter gets adopted as the next-gen IoT transport protocol, the Espressif ESP32-C6 (https://www.digikey.com/short/8vj302rf) is positioned to be the perfect module for fast integration and low cost. With pre-certified and encased modules, plus a ready-to-go SDK, you can spin up a prototype product in just a couple days. We recommend starting with the ESP32-C6-WROOM-1-N8 module to start, with tons of flash memory, you can always downgrade if you end up only needing 4MB of Flash. There's also an affordable ESP32-C6-DevKitC (https://www.digikey.com/en/products/detail/espressif-systems/ESP32-C6-DEVKITC-1-N8/17728861) that has all the basics on already for instant bring-up. Order from DigiKey today to get your ESP32-C6's by tomorrow afternoon so you can be ready for the future of IoT with WiFi, BLE 5 and Thread/Matter support baked in.

We're working on an updated version of our soil sensor, and thinking of making a version that has a coin cell battery on the back. However, we can't use the common 'retainer' style of CR2032 coin cell holder because we will have traces on the back that would make routing hard.Let's search for a battery holder that comes on tape - so we can pick and place it - but is SMT and is a proper holder that has small positive and negative pads. We want a slim and unobtrusive style if possible, and low cost so we can keep our BOM minimal.See the chosen part here https://www.digikey.com/en/products/detail/assmann-wsw-components/A-BAT-CH-C8-EA-ZSR3/19721188-----------------------------------------Visit the Adafruit shop online - http://www.adafruit.comLIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI will take you to Infinity and Beyond, with Infineon PSoC™ 4000T Microcontrollers (https://www.digikey.com/en/product-highlight/i/infineon/psoc-4000t-microcontrollers) and the CY8CPROTO-040T eval board (https://www.digikey.com/short/qhfjbt39) specifically designed to get you started with the 4000t series microcontrollers and using the Infineon-neé-Cypress CapSense technology for capacitive touch buttons and slider.The Infineon PSoC™ 4000T series of microcontrollers are based around the classic Arm Cortex M0+ core, running at 48 MHz and with 64K flash, 8K of SRAM. So, a great microcontroller for simple products/white goods that don't need USB or a graphical display, like headphones, rice cookers, tea kettles or electric toothbrushes. The chip is optimized for capacitive touch sensing, with timers and lots of capsense inputs, but not a ton of other peripherals: there's only two serial blocks that can be configured as I2C/UART/SPI, and no ADC/DAC or USB or CAN. As long as your product is intended to be low-cost, and simple, that's probably just fine!The real star of the show on these chips is the CapSense peripheral (https://www.infineon.com/cms/en/product/microcontroller/sensing-controller/capsense-controllers/capsense/), which has up to 16 inputs - out of 21 GPIO! These can be configured as "CSD-type" self-capacitance sigma-delta buttons or sliders, or as "CSX-type" mutual-capacitance X-Y grids (https://www.youtube.com/watch?v=SOOZII8cvT4). Capacitive sensing is great when you want products that react to touch without needing large and breakable tactile switches. For example, touch sensors on headphones can determine when they are inserted into the ear and when a finger is touching the body to pause or adjust volume (https://www.infineon.com/dgdl/Infineon-The_touch_sensing_HMI_in_wearable_and_IoT_devices-Whitepaper-v01_00-EN.pdf?fileId=8ac78c8c8a44f57b018a5f0711243a0f). Unlike buttons or encoders, there's no risk of eventual mechanical failure, rending a product useless: with a smooth clean surface you can still provide a full UI with low cost and maintenance.The Infineon PSoC™ 4000T series comes with the 5th generation of CapSense, which features autonomous DMA function in deep sleep, great responsivity, and moisture resistance. One downside of classic capacitive touch solutions is false 'ghost' triggering or sluggish 'touch blindness' when the touch surface is wet. This is a common issue with products that end up being used in a kitchen, bathroom, laundry room, while exercising or outside. That's because droplets of water have capacitance on the order of the human finger and so each droplet looks like a touch. Most capacitive sense implementations have a slow self-zeroing drift calibration procedure, but they don't handle sudden water sprays. CapSense 5th gen, by comparison, will maintain the same raw capacitive count even when there's spray, mist or droplets!Another neat feature is the autonomous sensing block, which allows ultra low deep sleep current of 6uA with touch-to-wake. Instead of powering up the whole core to do the capacitive touch reading and averaging in the main process thread, readings are done in a zombie mode so that we only wake up when touches are detected.If your next product design needs a reliable capacitive touch interface, the CapSense 5th gen-powered Infineon PSoC™ 4000T series (https://www.digikey.com/en/products/detail/infineon-technologies/CY8CPROTO-040T/22158824) is an excellent low-power Cortex M0+ chip that can act as the main processor of your product with high integration for a tiny BOM at an attractive price. You can get started fast by picking up a CY8CPROTO-040T eval board (https://www.digikey.com/short/j5hfb704) that has a programming/debug interface as well as button, slider and proximity sensing CapSense element. Order today and your CY8CPROTO will ship immediately, so that you can get started with your development by tomorrow afternoon!

SMT DIP switches are an excellent way to add quick configurability to a design - they are more compact than individual switches, more usable than cuttable pads, and less fiddly and error-prone than pin jumper shunts (https://www.digikey.com/en/products/detail/sullins-connector-solutions/NPC02SXON-RC/2618266).For a new design, there are 4 configurable switches but we wanted to keep the board nice and compact - so using 'full sized' 2.54mm SMT DIP switches (https://www.digikey.com/en/products/detail/te-connectivity-alcoswitch-switches/1-1825059-3/1021562) would take up half the PCB. Then we saw a design with a tiny SMT switch and realized that these handy components come in a compact 1.27mm size too!

This week's EYE ON NPI is catchy like an 80's pop song (https://www.youtube.com/watch?v=LPn0KFlbqX8), it's ams OSRAM's TCS3530 True Color Sensor (https://www.digikey.com/en/product-highlight/a/ams/tcs3530-true-color-sensor) It is a new light sensor from ams OSRAM that is pre-calibrated for CIE XYZ color temperature sensing output, without a lot of gnarly math!We're huge fans of ams's light sensors, one of our first sensor breakouts was the TSL2561, (https://www.digikey.com/en/products/detail/ams-osram-usa-inc/TSL2561T/3095179) a wide-input-range light sensor with an I2C interface. We followed that up with a breakout for the TCS34725 which can detect separate red, green, blue and clear channels. With a little math, color reflected off of objects can be calculated into RGB color-space - we used it to make an umbrella that matches whatever color it touches! (https://learn.adafruit.com/florabrella/) Since then, ams OSRAM has worked to create better light sensors that reduce the need for end-user calibration or a lot of microcontroller lifting. The chips have carefully tuned PN diodes to not only be able to report correct color values, but ideally also have little variation from sensor-to-sensor.The TCS3530 (https://www.digikey.com/short/qwt595fh) is the latest color sensor from ams OSRAM, and it's also their newest with XYZ color output! This means you can read CIE XYZ color values out directly from the driver, which is going to be the best way to model what a human eye sees (https://en.wikipedia.org/wiki/CIE_1931_color_space) - not just an optimal concept based on 'pure' RGB photodiodes. This makes it ideal for use with cameras, monitors, printers/copiers and other devices that have humans that are looking at the colors. By detecting ambient light temperature, monitors and camera sensors can adjust their white balance to have their color gamut appear more 'natural' even in yellowish incandescent or halogen, or blueish fluorescent light.The TCS3530 (https://www.digikey.com/short/qwt595fh) does this by having 8 separate PN diodes, each tuned to a specific frequency band, to cover from about 400nm to 750nm. The diodes are normalized by the ALS engine so that you don't get over-sensitivity to green or IR. The diodes are arranged in a 4-way symmetric array to get fully balanced readings across all frequencies: there's probably some reasoning to how the layout is done to avoid signal from one diode from affecting a nearby one, something ams has decades of experience with. A modulator and flicker detection system can sense light pulses such as those from incandescent bulbs (at 120 Hz) or monitors (30 to 60 Hz) so that we can sample at the same times during the wave, or sample long enough to capture a full waveform worth of light.Interfacing is fairly simple, although there are a few things to watch out for during integration. The sensor supports both I2C and I3C (https://www.youtube.com/watch?v=hC4zkvdVag4) so it's good for legacy or modern microprocessors. Note the chip requires no greater than 1.8V power and logic, so for 3.3V systems - a shifter will be necessary. Finally - the chip has a massive number of registers to tweak the settings. So while you could write a driver, you're probably best off using ams OSRAM's TCS3502 linux C kernel driver to base your implementation if you are not just using Linux/Android directly.If you want to add precision color sensing with pre-calibrated CIE XYZ outputs to your next design, the ams OSRAM's TCS3530 True Color Sensor (https://www.digikey.com/en/product-highlight/a/ams/tcs3530-true-color-sensor) is a top choice from a world leader in light sensing. And best of all, it's in stock right now at DigiKey for immediate shipment! Order today and you will get this compact all-in-one devices shipped to your door so you can start letting your true colors shine by tomorrow afternoon.

This week's EYE ON NPI is "aces", literally! It's ACES Group’s Vertical MicroSD Card Connectors (https://www.digikey.com/en/product-highlight/a/aces-group/vertical-microsd-card-connector), a great way to increase your enclosure design flexibility, maybe even improve BOM costs by not requiring a separate PCB for mechanical stability. MicroSD cards are a great way to add gigabytes of data storage for low cost and user-serviceability: they're available at just about any store - even grocery stores! Cards are usually under $10, and DigiKey stocks a huge variety of speeds and sizes. (https://www.digikey.com/short/b43p5rzq)The ACES card sockets come in two styles. The MSDV-2008-AKA0T01 (https://www.digikey.com/short/b449j9p5) is minimal, with the smallest size but no push-push eject - instead you have to pull the card out. The MSDV-2108-BK33T (https://www.digikey.com/short/7hnwrbd1) has push-push eject so it's easier to remove cards, but the overall package is much larger. The minimal one is also less expensive, about $1 in quantity whereas the fancy one is $1.60.Both come with the promise of accessing a MicroSD card at a perpendicular angle from the PCB - a design we've never seen before in a micro SD card holder! Historically, we've only seen and used 'right angle' style like the MSD-6-A from CUI (https://www.digikey.com/en/products/detail/cui-devices/MSD-6-A/21797113) - and DigiKey stocks tons of variants of MicroSD sockets (https://www.digikey.com/short/zfn2rcm3) such as hinged, push-pull, even super-skinny (https://blog.adafruit.com/2022/07/26/the-great-search-skinny-micro-sd-card-holder-for-raspberry-pi-cowbells-thegreatsearch-digikey-adafruit/). But, this is the first and only one we've ever seen that is 'vertical' not right angle, with all pins brought out plus card detection. The design is well thought-out with through-hole contacts plus 3 extra-wide mechanical stabilizers and a flat plastic seat so that customers jamming cards in off-angle won't tear the pads off.We've already picked up some of each to make a breakout board so folks can add these to their prototype design, but you shouldn't wait on us! If you want to add these two unique microSD sockets to your design - order from DigiKey today!

This week's EYE ON NPI will take you for a SPIN around the block - it's STMicroelectronics' STSPIN32G0 Three-Phase BLDC Controller (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stspin32g0-three-phase-bldc-controller) series of chips, featuring 250 or 600 V three-phase BLDC FET controllers with integrated embedded STM32 MCU! These chips are an 'all in one' solution to advanced motor control when you want to have sensors and tight integration, or a super tiny footprint.As budding robotics hobbyists, we've designed and stocked many products - like this Motor Shield (https://www.adafruit.com/product/1438) - to support a variety of small DC motors. Some well known varieties are: Hobby Servos, DC brushed motors, and steppers. Hobby servos are actually just DC brushed motors with a feedback circuit, so we'll ignore those. DC brushed motors are simple: apply a positive DC voltage to the two wires, and the rotor spins one way. Apply a negative voltage, they spin the other way. As you can expect from the name, inside are brushes, that connect from the rotating center to the two permanent magnets on the outer diameter (https://en.wikipedia.org/wiki/Brushed_DC_electric_motor). This makes them inexpensive, and very easy to use: simply PWM the voltage to change the speed, invert the voltage to change direction. Nothing more complex than an H-bridge is required. But the brushes do eventually wear out, or oxidize, or splinter. Which means the motors will eventually 'die' and need replacement. Fine for toys and simple products that have low usage, but not appropriate for white goods or automotive or anything where life-time and reliability are essential!Stepper motors are a tad more complex: in order to have precise movement, they use a bank of 4 electromagnetic coils to 'step' the axle around a little bit at a time (https://en.wikipedia.org/wiki/Stepper_motor). No brushes to replace! But they don't rotate fast: the point is they have small accurate steps, and they're kinda expensive. What if we could combine DC brushed motors and steppers to create... Brushless DC Motors? Wow, so smart! That's exactly what a BLDC is, a DC motor that has no brushes, but does have multiple windings that have to be synchronized right to rotate. They're a little more expensive than brushed motors, but not significantly. The biggest cost increase is in the driver complexity because you need to drive and sequence three branches, whereas the commutator/brushes on a brushed motor handles that for you.Normally folks will use their favorite microcontroller, then wire it up to a BLDC driver (https://www.digikey.com/short/3bf72p89), like the L6235Q (https://www.digikey.com/en/products/detail/stmicroelectronics/L6235QTR/2772201) which can push 2.5A per-bridge at up to 52V. But, wouldn't it be nifty if you didn't have to do any wiring, so that even for small designs, you can have a fully integrated motor controller with your main microcontroller. Or, you could use the microcontroller as an I2C or SPI peripheral that integrates the temperature/current/voltage/torque monitoring that you would normally have to manage as a interrupt-run thread on a main core. That's what we've got here with the STSPIN32G0 Three-Phase BLDC Controller (https://www.digikey.com/short/977t8ftv) series of chips. It's a ARM Cortex M0 STM32G031C8 (https://www.digikey.com/en/products/detail/stmicroelectronics/STM32G031C8U6/10300273) running at 64MHz and 64K flash / 8K SRAM, with standard peripherals, debug, and even some 5V-friendly GPIO. Inside, the STM is bonded to the control circuitry so that 3 sides are used for microcontroller interfacing, and the fourth side is high-voltage friendly with separated pads. Program it just like any other STM32G031C8, and just define the motor control pins to the bonded wires. And then you'll need to connect the 6 power IGBT/FETs to create the 3 driving half-bridges such as STGD6M65DF2 (https://www.digikey.com/short/7dwq7zw2)Are you ready to have a super-integrated BLDC driver board that comes with a top-notch Cortex-M0 and all the power-driving experience ST has to offer? You're in luck because the STSPIN32G0 Three-Phase BLDC Controller (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stspin32g0-three-phase-bldc-controller) is in stock right now at DigiKey for immediate shipment. Check out the all-in-one EVSPIN32G06Q1S1 eval board (https://www.digikey.com/en/products/detail/stmicroelectronics/EVSPIN32G06Q1S1/22470459) if you want to immediately start testing out the STSPIN32G0. Then place your order today so you can start putting your own spin on motor driving by tomorrow afternoon.

This week we saw a lot of chatter about Zilog's End-of-Life Notification (https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/5570/PCN_ZAC24-0029.pdf) for their Z84C series chips. These chips were pretty cool because they were true Z80 processors and available in DIP format! They are still in stock at DigiKey for now (https://www.digikey.com/en/products/detail/zilog/Z84C0010PEG/929206) and there's a last-time-buy, so if you happen to want some large quantity, it's possible to put in a request for one last batch. There are also other Z80 processors available, so you're not totally out of luck if you need some 8-bit goodness. In theory, you could even wire-wrap or breadboard using a QFP-to-DIP adapter plate.

ATMakers emailed and asked if we'd make a Trinkey (https://www.adafruit.com/search?q=trinkey) with a TRRS jack (https://www.adafruit.com/product/5764) on the end, for making customizable HID devices that use simple 3.5mm audio jack connectors. ideally something that will make AT - Accessibility Technology - projects EZ to build and maintain.here's our take on it, what's interesting is each pin of the jack - including the two switches for tip and ring1 - connect to GPIO / analog inputs on the SAMD21. there's no pre-defined VCC or GND because different switch and joystick makers have different configurations and we might want to change around what pins are power, ground, pullups, etc!this board will be great for use with CircuitPython to make any sort of AT switch or potentiometer interface super fast, to demo it we've written up a quick CPy sketch that will listen for two switches, and when they're pressed, blink the NeoPixel and emit keypresses as if its a keyboard. code is in the PR for this board (https://github.com/adafruit/circuitpython/pull/9190#issuecomment-2067764251) since we have great HID support it could also be a mouse or joystick device and it will work with any computer/tablet/console with a USB port.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #atmakers #accessibility

Psst...this week's EYE ON NPI is no secret, and despite having the word "Pseudo" in the name, it's the Real Deal: This week it's ISSI's Serial and Quad PSRAM chips (https://www.digikey.com/en/product-highlight/i/issi/serial-ram-and-quad-ram-solutions), an excellent addition to your next microcontroller board to quickly boost your RAM stack to megabyte proportions!Microcontrollers have come a long way since 8-bit chips like the ATmega328 (https://www.adafruit.com/product/123). What used to be a luxurious 32 KB of flash memory and 2 KB of SRAM is now nowhere-near-enough storage for handling the big computation requirements we're trying to squeeze into embedded products. It used to be enough to handle some buttons, blink a few LEDs, maybe at best read a sensor and control a motor. Now we need internet connectivity, full graphics support, and machine learning algorithms running on large sensor data sets! As we've seen, microcontrollers have evolved from 8-bit AVR to Cortex M0 to Cortex M4 and even M7 - or if you're a fan of Espressif chips, Tensilica/RISC-V 240 MHz processors. But what you are paying for in a microcontroller is often related to the density and size of the die, and on many processors, the RAM and FLASH can start to take up a dominant amount of die real-estate. SRAM and Flash may also require larger nm 'processes' that are harder to book. As a result, we're seeing chips like the RP2040 (https://www.digikey.com/en/products/detail/raspberry-pi/SC0914-13/14306010) that have on-chip SRAM but no longer have on-chip Flash memory. Instead, you're expected to pick up a QSPI flash chip and wire it up to the 6-pin interface. By clever usage of on-chip instruction cache, you can get close to on-board FLASH speeds but with the flexibility and size of external memory: it's hard to find a chip with more than 1 MB of internal FLASH but you can easily get 16 MB of external memory like the ISSI IS25WP128 (https://www.digikey.com/en/products/detail/issi-integrated-silicon-solution-inc/IS25WP128-JBLE/5431600) for only a couple bucks!OK now you've got plenty of space for your code, but what about RAM? That's where you'll be buffering graphics, storing data to process, or for IoT products, storing large packets of data that may need to be encrypted before sending/receiving. SRAM is also big and kinda expensive, so it's no surprise that many advanced processors these days also support external RAM chips. Now, most folks aware that microprocessors (as opposed to microcontrollers) have required external RAM for quite a long time - but often those used large DRAM chips with 8, 16 or 32-bit parallel interfaces like the IS42 series (https://www.digikey.com/en/products/detail/issi-integrated-silicon-solution-inc/IS42S16400J-7TL/2708623). These of course are not going to work when you only have 32-ish GPIO available. That's where 8-pin PSRAM chips come in - and we're starting to see lots of 'low pin count' microcontrollers support these. For example the iMX RT1062 (https://www.digikey.com/short/0fhbdwv0) used in the Teensy 4.1 (https://www.adafruit.com/product/4622) supports PSRAM - check the SOIC-8 footprint on the bottom. Likewise the ESP32 series has wide support for PSRAM, their modules come with 8-SOIC 2MB chips very often. The extra PSRAM comes in handy when doing large IoT projects where you have to buffer an entire image, or JSON structure. Especially over TLS connections that require a lot of RAM to process! Note that while you could use the ISSI PSRAM chips with any processor, thanks to the generic SPI or QSPI interface, you really do want a chip to have 'native' PSRAM support so that the compiler and core will automatically map the PSRAM out so it is accessed transparently to your code. You'll likely need to enable PSRAM support in your toolchain and of course wire it up to the supported QSPI interface pins. Also, sometimes you need to be careful about where some memory goes, like volatile or interrupt-accessed addresses. Sometimes you also have to tell the compiler what ID code or command-set to use, since things like enabling the QEN bit can vary from chip to chip.With a universal pinout and speedy 100MHz clock rate, PSRAM is a fast and easy way to make your micro roomier. If you're not sure which to pick, maybe start with the IS66WVS2M8BLL (https://www.digikey.com/short/29b1dzqf) a 2 MByte / 16 MBit 3.3V-logic SOIC-8 PSRAM chip. If you're ready to add encyclopedic memory in your next design, you are in luck, because the ISSI Serial and Quad PSRAM chips (https://www.digikey.com/en/product-highlight/i/issi/serial-ram-and-quad-ram-solutions) are in stock right now for immediate shipment! Order today and you'll get your chips in hand by tomorrow afternoon.

This week on the Great Search, we saw someone on social media talking about repairing an old device that has a 'split' supply with multiple voltages. (https://twitter.com/dorksince93/status/1779346977861615666) Usually your AC-DC adapter converts 110~220VAC into 12VDC. But sometimes you need +12V, -12V, plus maybe a 5V for good measure. And sometimes the connector ends up being a DIN because it has to support so many different voltages! (https://twitter.com/dorksince93/status/1779346977861615666/photo/1) Let's show how we can find this kind of device, as well as a matching cord (https://www.digikey.com/short/n8z3h7nn) on DigiKey so that we can resuscitate some old devices and keep them out of the landfill!See the chosen part on Digikey https://www.digikey.com/short/m408ftf3Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
We designed this CH552-based QT Py board before the chip shortage, but now parts are plentiful so we made some prototypes and are trying out the CH55xduino (https://github.com/DeqingSun/ch55xduino) board support package. and, it works! but watch out, its C not C++ so you can't use the huge collection of existing libraries and drivers. however, for about '40 cents' per chip, you get a 8051 with native USB that can do CDC/HID, has 4x 8-bit ADCs, hardware serial, I2C, SPI and doesn't need a crystal or a lot of passives. obviously there's down sides to such a minimal 8-bit microcontroller chip but we think it could be super fun for some very basic USB projects!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #electronics #diy

This week's EYE ON NPI will make you say "Yeee-haww", to the buckin'-and-boostin' bronco known as the Richtek RT6160A Buck-Boost Converter with I²C Interface (https://www.digikey.com/en/product-highlight/r/richtek/rt6160a-buck-boost-converter). The RT6160A is a high-efficiency, single-inductor, synchronous buck-boost converter that can provide up to 3 Amps of current to a dynamically-configurable voltage from 2.025V to 5.2V. With an amazing 2uA quiescent current, this chip lets you add an advanced power supply for the price of an LDO that will let you design with the smallest possible battery.We're big fans of Richtek for low quiescent power supply chips - our favorite 3.3V LDO is the RT9080-33 (https://www.digikey.com/en/products/detail/richtek-usa-inc/RT9080-33GJ5/6161634) which can provide up to 600mA with a 0.5V dropout, and a really nice 4uA quiescent current. This is great for deep-sleep wireless projects where you've got a chip with ultra-low power snooze modes, like the ESP32 - we were able to get down to 10.5 uA in deep sleep thanks to the RT9080! (https://learn.adafruit.com/adafruit-itsybitsy-esp32/low-power-use). Compare that to the AP2112K which we used to use, has a quiescent current of 55uA.However, the RT9080 is a LDO fixed at 3.3V@600mA - and of course, LDOs have that dropout which translates to power lost. If you want to sip every last Coulomb out of the battery on hand, you'll need a DC/DC converter. Usually we see a buck converter - since you are converting from a Lithium Polymer battery, you'll have 3.7V nominal, 4.2V peak voltage and maybe you'll buck that down to 3V. If you want to really get the best possible range of performance, you can go with a buck boost (https://en.wikipedia.org/wiki/Buck%E2%80%93boost_converter). That way you can buck down from 3.4-4.2V and then as the battery starts drooping, the chip switches into a boost mode to cover the 2.7V~3.2V range.The RT6160A is a Buck-Boost converter that seems well designed for battery-powered projects, with an input and output range of about 2 to 5V. The default output is 3.3V and you can 'select' between two voltages by toggling a GPIO pin. This makes it easy to adjust the desired voltage and then swap from 'high' to 'low' voltages without an I2C command. Why would you want two voltages? Well, you could use 3.3V or greater for when you want the best performance from a radio, then drop down to 2.5V when the radio isn't on and you want to reduce both the conversion current and also reduce your chip quiescent current: most microcontrollers will use lower current at lower voltages since they are not pushing around as much current onto the internal logic FETs. Combine this with a microcontroller's dynamic clock frequency configuration and you've got a simple system to squeeze more current out of your battery. And usually you have to 'spend' a lot of current to run the DC/DC converter, but this chip has an amazing 2uA quiescent current - lower than most LDOs we've used, and amazing for an up-to-3A output device.If you want to have the lowest quiescent, highest-flexibility power management chip in your next design, the Richtek RT6160A Buck-Boost Converter with I²C Interface (https://www.digikey.com/short/hv7fm4nt) is an excellent choice: Richtek really know their power supplies and they keep it nice and simple so you can get to integration instantly. Best of all, DigiKey has the RT6160A (https://www.digikey.com/short/hv7fm4nt) in stock right now, for immediate shipment, and $1.32 by the reel! All you need is some ceramic caps and an inductor. For fast testing in your application, there are also some EVB_RT6160AWSC (https://www.digikey.com/short/0p80hqvj) eval boards in stock. Order today and you can be waving your cowboy hat in celebration by tomorrow afternoon.

The ESP32-C6 (https://www.adafruit.com/product/5672) is Espressif’s first Wi-Fi 6 SoC integrating 2.4 GHz Wi-Fi 6, Bluetooth 5 (LE) and the 802.15.4 protocol. It brings the goodness you know from the low-cost C3 series (https://www.adafruit.com/product/5337) and improves it with Zigbee/802.15.4 at 2.4Ghz. That means it could make for great Matter (https://csa-iot.org/all-solutions/matter/) development hardware! We took our Feather ESP32-S2 (https://www.adafruit.com/product/5000) and swapped out the 'S2 for a C6. Plus some re-routing and here's what we've got: a C6 Feather with lots of GPIO, lipoly charging and monitoring with the MAX17048, (https://www.adafruit.com/product/5580) NeoPixel, I2C Stemma QT port, and a second low-quiescent LDO for disabling the I2C and NeoPixel when we want ultra-low power usage. We also tossed a BME280 (https://www.adafruit.com/product/2652) on there, so you could use it immediately as a low power temp/hum/pressure sensor.Now it's time to do the bringup - we like to blink LEDs, toggle pins, and also check that NeoPixels glow up. Good news: so far everything works! We're going to keep at it and see if we can maybe get a simple Matter demo going before we book the PCBs#adafruit #feather #esp32c6 #featherboard #wifi6 #bluetooth5 #zigbee #matteriot #lowpower #iotdevelopment #tempmonitoring #pcbdesignVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

Full tutorial: https://learn.adafruit.com/led-festival-coat-with-mapping-and-wledThis guide will demonstrate two different methods of lighting up a coat:Fur Trim Lights: String LED lights inside the ubiquitous furry trim that's found on so many Festival jackets. This is a fairly easy build that doesn't require a lot of sewing or coding skills.Light Matrix Panels: Create a 3-panel LED matrix between the coat fabric and lining that runs 2d animations on the body of the coat. This is a more complicated build that requires some coat deconstruction and sewing, and requires some detail-oriented number work to get the LED map created.The wiring is the same for both builds, and it's possible to do both in the same coat, though that makes the software setup pretty tricky.This guide uses the free, open-source WLED software. It's easy to install and to use. Control the lights with your phone or computer over your WiFi network when you're at home, or via AP-MODE (access point mode) when you're out and about. WLED comes with loads of customizable animations for your lights.

our popular USB Host FeatherWing (https://www.adafruit.com/product/5858) lets anyone with a Feather board add USB Host support via the MAX3421E (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/MAX3421EETJ-T/1455883) chip - a tried and true SPI-to-USB converter. here's a tinified version, that fits on the back of any QT Py or Xiao board. use SPI plus a CS and IRQ pin and you're ready to rock. theres tinyUSB support for me MAX3421 chip (https://github.com/hathach/tinyusb/issues/2001) for Arduino which means its trivial to connect to a USB keyboard, mouse, storage key, or a USB serial device like this Trinkey! We're using our SHT45 Trinkey (https://www.adafruit.com/product/5896) as a demo board since its an easy way to quickly verify enumeration and data transfer. since the BFF/QTPy form-factor is too small for a proper USB Type A, we're going with a micro B, you can just an OTG adapter to turn it into a full size A (https://www.adafruit.com/product/1099)Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
This week on the Great Search, we saw a post on social media asking for good quality through-hole 1% resistor kits. (https://twitter.com/mightyohm/status/1772784883313836284). We've bumped into the same issue as Jeff, where getting inexpensive kits are poorly packaged and are '1/8W' style with skinny leads that do not grip into breadboards. Thankfully, DigiKey has such in stock - let's check out the resistor packs available and which ones you may want to start with so you don't break-the-bank.See the chosen part on Digikey https://www.digikey.com/short/bjn570tfVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/
Back in 2021 we were on a real tear (https://blog.adafruit.com/?s=trinkey) making a whole bunch of 'low cost and easy to use' USB devices called Trinkeys (https://www.adafruit.com/search?q=trinkey): the idea is you could just shove it into your USB A port on a computer or laptop and get instant access to a few NeoPixels (https://www.adafruit.com/product/4870) or an APDS9960 proximity sensor (https://www.adafruit.com/product/5022) or a rotary encoder (https://www.adafruit.com/product/4964). buuuut then there was a massive chip shortage (https://blog.adafruit.com/category/adafruit-video/chip-shortage/) and we couldn't get any ATSAMD21E18's which power most of the designs. welp, we have lots now. so lets keep designing Trinkeys! This is a trinkey with an SHT45 (https://www.adafruit.com/product/5665), a favorite humidity and temperature sensor! The factory code will just spit out temperature and humidity over the USB Serial port in CSV format for easy integration. there's also a neopixel and a captouch sensor. we added a U-shaped cut-out to minimize self-heating from the neopixel or samd21 chip to get the best accuracy, we'll also have a version with an SHT41 that's less expensive (https://www.adafruit.com/product/5776)Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

Once in a while we find products that have center NEGATIVE DC power jacks and they really make us mad because who keeps around both positive and negative polarity versions of every voltage? now, hopefully USB PD https://www.adafruit.com/product/5807 will solve this long term, but till then this 2.1mm DC flipper flopper adapter will connect in to out and out to in and voila - your standard center-positive is now center-negative. or vice versa! how handy is that.#adafruit #cable #polarity #dcflipperVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

We got a request from some folks for "solder-less pin header" - these snap-apart headers look just like your regular pin headers but they have a little slot in the shorter end that can make a cold-contact with pads on a PCB. only thing is, since they are wedged in, you need some good leverage and it takes a few tries to get the hang of it. but they do work, we checked continuity! for quick prototyping, these could be kinda handy. coming soon to the adafruit shop....Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #electronics #diy

Full tutorial: https://learn.adafruit.com/sound-reactive-paper-lanterns-with-led-fxCreate an array of paper lanterns and control them with sound.This guide uses a Feather ESP32 V2 loaded with the free, open source WLED software.Buy on the Adafruit Website: https://www.adafruit.com/product/5400WLED runs on the Feather, using WiFi to allow you to control the lights with your phone, PC, or any wifi-enabled device. This is a lot of fun, and will make for a beautiful piece of light art in your space that's easy to control and program with your phone.But this guide goes further! WLED interfaces seamlessly with LED Fx, an open-source program that runs on your computer to capture and analyze sound, either from your music player or from your computer's microphone. It takes the sound and translates it into light effects, so your lights can run sound-reactive animations over WiFi without needing to add a physical microphone.WLED has sound reactive effects. Why not just use WLED?WLED does have sound reactive modes available, but the sound needs to be run and processed through a small microphone soldered to your ESP32. These microphones don't have the same quality pickup as the one on your PC, and may not be physically located where the sound is optimal. The effects don't have as many controls, and tend to be a little "blinky".LED Fx gives you great sound input and a lot of solid animations with controls that allow you to really dial in your animations. It's just as easy to use but I've gotten much nicer results with LED Fx.Visit the Adafruit shop online - http://www.adafruit.comErin St Blaine: www.erinstblaine.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

A year ago we designed a high-current-output Infrared Transmitter STEMMA (https://www.adafruit.com/product/5639) and had to find a high brightness right angle LED. (https://blog.adafruit.com/2022/10/18/the-great-search-bright-side-emitting-infrared-smt-led-thegreatsearch-digikey-digikey-adafruit/) Today we sat down to design the other side, a receiver. We did find a 38KHz receiver that will work, but it got us thinking about 'code learning' IR projects, (https://learn.adafruit.com/building-an-infrared-transmitter-and-receiver-board) where we don't want to demodulate out the 38KHz or whatever frequency, but retain the signal so we can determine the carrier frequency as well as the code. We were all ready to go with the TSMP77000 after our initial search, but then noticed it was EOL (https://www.digikey.com/short/qw72wwqh). Will we find a replacement that is currently manufactured?

This week's EYE ON NPI will galvanize your next design, with robust galvanic isolation specifically for I2C devices: we're highlighting the Analog Devices ADuM1252/3 Bidirectional I²C Isolators (https://www.digikey.com/en/product-highlight/a/analog-devices/adum1252-bidirectional-i2c-isolator). They are available in two flavors: as the unidirectional ADuM1253 (https://www.digikey.com/short/0w8fq3w5) and bi-directional ADuM1252 (https://www.digikey.com/short/r4j3tcrf). These little SOIC chips provide trustworthy isolation up to a shocking ±10 kV surge, with pending safety and regulatory approvals, so you can feel confident that your design is created as safe as possible.Digital isolation (https://www.analog.com/en/product-category/isolation.html) is essential when dealing with medical, industrial or robotic designs. For industrial/robotic applications, the motors are very noisy and you want to make sure that there is no direct path for that electrical noise to your delicate sensors or microcontrollers. With medical cases, engineers are often tasked with measuring very fine sensors, with uV signals, and providing repeatable data that is used for life-or-death decisions, while also making sure that the 'DUT' is never exposed to dangerous voltages all in an environment with tons of other equipment, some of which may be misbehaving...that's a lot of pressure! The ADuM1252/3 is specifically designed for isolation of I2C signals: you can't just use 'any' isolator because I2C is a bi-directional data protocol that uses pull-ups on open-drain data and clock lines to communicate from controller and peripheral. The ADuM1252 (https://www.digikey.com/short/r4j3tcrf) has bi-directionality on both SDA and SCL, useful for 'multi-controller' modes or when clock stretching is used. The ADuM1253 (https://www.digikey.com/short/0w8fq3w5) has unidirectional SCL for most common I2C devices, and is a little less expensive.The ADI iCoupler technology uses 'galvanic' isolation, that's not the same as optoisolation! According to ADI, you'll get much better data-rate performance and isolation with galvanic compared to optoisolation. Also, lower power since you don't have to turn on/off an LED. Plus you can also use iCoupler for power transfer, which optoisolation cannot do. (https://www.analog.com/media/en/technical-documentation/frequently-asked-questions/icoupler_faq.pdf) The way iCoupler works is by creating a tiny transformer (https://en.wikipedia.org/wiki/Transformer) with two sets of metal coils, separated by an isolating polyamide layer. For data transfer, little coils are used and for power transfer, bigger coils can handle a couple mA! Of course, if we're using a transformer, you know that DC signals cannot be passed through, only AC; and data has a DC component plus isn't a sine wave. That means that there's also a data-to-AC codec on board that will turn I2C signals to AC, then back to I2C. All this is managed transparently so you don't have to worry about it, just treat it as a single I2C bus.There's also a couple nice extras that are helpful if you're trying to make I2C more fault-tolerant. Pre-charge circuitry and 'stuck' detection allow hot-swapping, either purposeful or accidental. The two isolated sides are not connected together until the Side2 half is in a neutral-bus condition. Since each side is separate, you can also use the ADuM1252/3 (https://www.digikey.com/short/1vbn4hcb) for level shifting: either half can be between 1.7 and 5.5V power and logic. With the fast iCoupler codec, you can get up to 2 MHz clock rate for fast I2C data transfer. If you need iCouplers for other protocols like USB or SPI - Analog devices has those available as well, each version is tuned for the usage so you get the best performance.If you need high performance galvanic isolation for your next I2C design, the Analog Devices ADuM1252/3 Bidirectional I²C Isolators (https://www.digikey.com/en/product-highlight/a/analog-devices/adum1252-bidirectional-i2c-isolator) will do an excellent job at creating a code-transparent galvanic barrier for up to 2 MHz bidirectional I2C communication. And best of all, both the unidirectional ADuM1253 (https://www.digikey.com/short/0w8fq3w5) and bidirectional ADuM1252 (https://www.digikey.com/short/r4j3tcrf) are stock at DigiKey right now for immediate shipment. Order today and you'll be gallivanting your way to iCoupler bliss by tomorrow afternoon.See the ADI video https://www.youtube.com/watch?v=4cH-ym9QJlQ

This week's EYE ON NPI is super phat not unlike a pair of ultra wide JNCOs (https://jnco.com/collections/womens-1/products/the-camilla-jeans-27-vintage-houndstooth) it's the Laird Sera NX040 Ultra-Wide Band and Bluetooth Combo Module (https://www.digikey.com/en/product-highlight/l/laird-embedded-wireless-solutions/sera-nx040-ultra-wide-band-and-bluetooth-combo-module), a compact solution that combines the best of NXP UWB and Nordic BTLE into a single easy-to-use module that is ready for instant integration into your location-based identification products or projects.We often get folks asking how they can do indoor location projects: where an object is tracked in a 2D or 3D space, with high precision. For outdoor projects, most people use GPS/GNSS (https://en.wikipedia.org/wiki/Satellite_navigation) which can give 10 meter accuracy anywhere in the world. Or, sometimes people use cell tower triangulation (https://blues.com/blog/use-cell-tower-and-wi-fi-triangulation-to-achieve-pin-point-locations-without-gps/) to give rough estimates of location world-wide. However, both of these require you to be outside, with either network connectivity or a GNSS fix - and like we mentioned, you can't get better than 10 meter accuracy without very expensive RTK modules (https://blog.adafruit.com/?s=eye+on+npi+rtk). Indoors, sometimes its possible to use WiFi time-of-flight, or BTLE ToF / AoA (https://blog.adafruit.com/2021/08/19/eye-on-npi-xplr-aoa-direction-finding-and-indoor-positioning-explorer-kit-eyeonnpi-digikey-ublox-digikey-adafruit/)More interesting, we can also use multiple stationary transmitters to determine the 3D location of a mobile device. Instead of looking for one pulse, we encode the transmitter ID into the pulses, and then can correlate each received pulse to the fixed 3D location of the station. As long as we have 4 stations, we can solve for XYZ and yes that's a lot of stations but you can get 10cm accuracy, which blows away BTLE and WiFi RSSI or ToF methods. Note that doing the triangulation on UWB pings requires a ton of math which is why having a ready-to-go module is great because NXP and Laird will provide example code to get you started.While most folks think of UWB as a 3D locator, NXP promotes some other use cases - most notably peer-to-peer payments (https://www.nxp.com/company/about-nxp/nxp-collaborates-with-ing-and-samsung-to-pilot-industrys-first-uwb-based-peer-to-peer-payment-application:NW-NXP-COLLABORATES-WITH-ING-AND-SAMSUNG-TO) and keyless car access. The key-less entry proffer is the most timely as there's been a spate of car theft rings that use relay attacks to amplify the signal from a key fob (https://www.nytimes.com/2015/04/16/style/keeping-your-car-safe-from-electronic-thieves.html) if the car is parked close to the house and the keys are kept near the door. Thanks to UWB now being included in iPhones and in the iOS API,you can likely have customers use their iPhones to directly interact with the Sera NX040.To save you time and integration costs, the Sera NX040 (https://www.digikey.com/short/hmzt8whq) include the NXP UWB chipset and all supporting circuitry, plus a Nordic nRF52833 (https://www.digikey.com/short/jj9r27p2) which is a Cortex M4 with all the peripherals, plus the best Bluetooth LE radio on the market. Nordic's chips are especially good at low-power use-cases so battery-powered designs will benefit from this combo. The NXP SR040 is wired to the nRF via SPI - you'll use the NXP SDK for that, which you need to contact NXP for. Or you can use the Laird MicroPython build which comes with some ready-to-go examples. The Seras are available with either built in tuned antenna (https://www.digikey.com/short/hmzt8whq) or a external antenna connection - you'll need to pick up a NanoUWB antenna (https://www.digikey.com/short/1wq0t5r0) to match (https://www.digikey.com/short/ctw5m4t8). As you can expect for a device with two wireless components, proper layout is essential to get good performance from both the BLE side and the UWB side - check the Laird documentation on how to set up keep-outs and ground planes. Finally, if you want to get started you can always pick up the NX040 Eval Board (https://www.digikey.com/short/hhtqhwc9) which has SWD debug for programming the nRF, USB connection for MicroPython or Zephyr debugging, and a separate RP2040+MikroBus+Qwiic half that can be used for adding sensors or displays.Whew, this NPI was not just ultra-wide but ultra-long: we learned a lot while researching the Sera NX040 (https://www.youtube.com/watch?v=KWf9fcx26wg) and the modern uses of UWB! If you want to get in on this multi-purpose RF protocol, you're in luck because DigiKey has the Laird Sera NX040 UWB+BTLE Module (https://www.digikey.com/short/hmzt8whq) and accessories in stock right now for immediate shipment. Order today and they'll send you parts faster than an UWB pulse so you can get started with integration in nanoseconds.

This week's EYE ON NPI is virtually the best chip you could get for VR tracking - it's the TS4631 Light-to-Digital Converter (https://www.digikey.com/en/product-highlight/t/triad-semiconductor/ts4631-light-to-digital-converter) a specialized mixed-signal ASIC that is designed especially for folks who want to design accessories for the SteamVR (https://store.steampowered.com/app/250820/SteamVR/) and specifically, HTC Vive hardware (https://www.vive.com/us/). Thankfully, this chip is available without restriction or NDA, which means it's theoretically possible for anyone to design tracking technology without the hard part of making the fixed-base-transmitters.Precision 3D tracking within a room is incredibly hard: Cameras can kinda do depth perception but they require a lot of computation and often make mistakes on object recognition. You can try using UWB but it's very pricey and has precision limitations. HTC Vive solves this by using IR light, which is not-sensitive to room illumination, doesn't have RF interference, and is fairly inexpensive. Each 'lighthouse' acts like a lighthouse: after an initial Infrared burst for sync, it sweeps IR over X & Y directions. Check out Alan Yates' detailed talk for how this design works (https://www.youtube.com/watch?v=75ZytcYANTA) The object being tracked has an IR photodiode, which catches the sync pulse, then measures the time between that and the X and Y sweeps. It does this for each lighthouse. With some fun matrix math (https://trmm.net/Lighthouse/), it can then calculate it's X Y Z coordinates with respect to the Lighthouses and, given we know the location of those Lighthouses during an initial calibration step, we can localize that IR diode within the fixed coordinates of the room we're in.That means that if you want a device that can detect the IR pulses and sweeps, all you need is an IR photodiode like the OSRAM BPW 34 (https://www.digikey.com/short/b5jn4pnp) and a bunch of analog electronics to filter out ambient noise, detect the carrier frequency, and give you the timing pulses detected. Or, you can save yourself a ton of effort, and just go with the Triad TS4631 (https://www.digikey.com/short/fwr173wh). All you need is the photodiode and a couple simple passives and you can have a configurable sensor analog front end at low cost and low complexity. In fact, that's what nearly all Vive-compatible hardware uses. (https://twitter.com/SadlyItsBradley/status/1634146181755355136)The Triad TS4631 (https://www.digikey.com/short/fwr173wh) comes in a compact 0.4mm-pitch 9-pin BGA package, which thankfully uses the center ball as a second ground so no buried vias are required. Give it 3.3V power, a BPW 34 S (https://www.digikey.com/short/p8j9r7z0) photodiode, and a couple passives for the power supply, and it's ready to go! There's two output pins for the Envelope and Data from the IR signal. Those two pins are also the I2C configuration pins, and you can use any microcontroller to read and write the configuration registers that let you set up the gain, thresholds and sleep modes. There's a library for the TS4231 (https://github.com/TriadSemi/TS4231) available from Triad, and since the TS4631 mostly improves the TS4231's power usage, you can likely start your microcontroller interfacing and development with that code.There's also lots of other folks playing around with the Triad TS4631 (https://www.digikey.com/short/fwr173wh) and TS4231 (https://www.digikey.com/short/fmcj4wft) which means that you can find hobbyist projects for design inspiration. We found some great info from famed hackers CNLohr (https://hackaday.io/project/153224-ts4231-esp8266-lighthouse-tracking) including libsurvive for desktop tracking (https://github.com/cntools/libsurvive/), Trammell Hudson (https://trmm.net/Lighthouse/), and other YouTube makers (https://www.youtube.com/results?search_query=ts4231). There's also a published project called HiveTracker (https://hivetracker.github.io/) that has hardware and firmware for a fully-designed tracker board with Bluetooth LE as the backchannel.If you want to get started with making 3D-trackable devices for VR or AR applications, it's great to not have to build the whole system from scratch. With the Triad TS4631, (https://www.digikey.com/short/fwr173wh) you can integrate into the existing SteamVR/HTC Vive ecosystem or you can chart your own path with their hardware and your own software. Either way, you'll want to pick up some TS4631's and you're in luck because DigiKey has them in stock right now, for immediate shipment! Order today and you can be tracking in cyberspace by tomorrow afternoon.

This week we worked on some Picowbell designs, including a prototyping plate that includes a battery charger. We recycled charging and switch-over designs from our Feathers but then we realized we never showed off the charger chip itself! We tend to use the MCP73831, but there's approximately 4902 different variants! Let's take a look at how to select a charger that matches your battery: voltage and charge rate are the biggest things to check. There's also other extras like LED indicators, time-outs, and load-sharing/prioritization.See the chosen part on DigiKey https://www.digikey.com/short/d3qvhj2qVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is gonna give it to up high...then down low (https://en.wikipedia.org/wiki/High_five) ...ready to measure, never too slow! It's STMicroelectronics' TSC1641 Digital Power Monitor (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/tsc1641-digital-power-monitor), a high-precision temperature, voltage, power, and temperature monitoring chip with I2C or I3C interfaces for integration with modern microcontrollers and microcomputers. This chip is great for tracking actual power usage into motors, LEDs, batteries etc. to detect anomalies or conserve power, with a tiny footprint and flexible usage.The TSC1641 is a modern take on the old-shunt-resistor-into-an-opamp method of power monitoring (https://learn.adafruit.com/portable-solar-charging-tracker/analog-stuff). For one, the TSC1641 can handle high or low-side measurements. That means you don't run the risk of having your grounds floating above earth, or managing multiple reference voltages.Also of course wiring is a snap, you just insert the board in between the power rail and load. Second, it can read up to 60VDC voltages - great for big battery packs, automotive or robotics. Third, it will calculate power and low-pass filter for you so you aren't affected by spiky power usage. Fourth, there's an onboard temperature sensor tossed in. Finally, this chip is not just I2C compatible, it has I3C support https://en.wikipedia.org/wiki/I3C_(bus) which makes it a great investment for long-term designs as I3C catches on and is supported in the next generations of microcontrollers.We covered I3C in a previous EYE ON NPI (https://blog.adafruit.com/2022/05/12/eye-on-npi-nxp-p3s0200gm-i3c-switch-with-hardware-select-and-enable-eyeonnpi-nxp-digikey/) so check it out for more details. To sum up fast: I3C is back-compatible with I2C but has push-pull logic support for up-to-12MHz speeds, in-channel interrupts so a separate IRQ line is not needed, and dynamic addressing so there's no address collision. A great update to all the things that make us batty about I2C. Support for I3C on the controller-side is still rolling out so you probably will use this chip in I2C mode for now, but your firmware can be adjusted-up to I3C on a future revision.This chip is a great response to the INA series from TI - and we love competition, it's great for all engineers when the chip companies clamor for our business by iterating and improving! Compared to the INA237, the ST TSC1641 (https://www.digikey.com/en/products/detail/stmicroelectronics/TSC1641IQT/21725159) has the same specs but is 10% less, plus you get that I3C support that none of the INA chips have yet.The high level of integration means you only need to spec a shunt resistor. The resistor selection will have to balance the dynamic current range measurable with the 16-bit precision. If you pick too small of a resistor, you'll max out the measurable current faster. If you pick too large of a resistor, you wont get good accuracy at low currents. Check the datasheet for how to select a good resistor and then how to tell the chip what value you've chosen: that will let the TSC1641 perform the power/current/voltage calculations on its own without you having to do any math. If you'd like to get started fast, there's also an eval board that is Arduino-shield-compatible (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/steval-digafev1-evaluation-board-for-the-tsc1641), some firmware is provided for the Nucleo series of ST dev boards to evaluate without any soldering or coding.If you're interested in the STMicroelectronics TSC1641 Digital Power Monitor (https://www.digikey.com/en/products/detail/stmicroelectronics/TSC1641IQT/21725159) you are in luck because it's in stock right now at DigiKey! Order today and it will ship faster than you can give a high-five, and be at your doorstep tomorrow afternoon for your power-monitoring pleasure.

This Great Search is a big throwback to every electrical engineer's first power supply. The LM7805 is a mainstay regulator, available in TO-220 package, as well as TO-92 and SMT. Today, we found a social media post of someone repairing a SEGA Master System (https://twitter.com/nosIndulgences/status/1758586503868080259) where they needed to replace the LDO. Let's look for a drop-in replacement with 1A or more of current. Also, maybe we'll peek at some alternative products that can provide more current output or lower drop-out.See the chosen part on DigiKey https://www.digikey.com/en/products/detail/stmicroelectronics/L7805CV/585964Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
OK so UPDI actually stands for Unified Program and Debug Interface (https://onlinedocs.microchip.com/pr/GUID-DDB0017E-84E3-4E77-AAE9-7AC4290E5E8B-en-US-4/index.html?GUID-9B349315-2842-4189-B88C-49F4E1055D7F) but this board is so smol and kute that i will call it the Unusually Playful Device Interfacer and pat it's head when it does a good job. it's designed to make programming modern ATtiny chips very easy because it has 3 or 5V power&logic select, power and transmit indicator LEDs, and a quick cable for poking into a breadboard. To test it we're using an RP2040 because we have CH340 via USB Host support (https://github.com/adafruit/Adafruit_TinyUSB_Arduino/commit/8d996db5075b278e903024d026342b9f6ec755af) - we transmit data from the hardware Serial port and make sure it's received by the USB serial port, and vice versa.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is a sweet valentine, as the Bard famously spoke "What's in a connector? That which we call a Hirose DF40F Series Board-to-Board connector by any other word would smell as sweet" (https://en.wikipedia.org/wiki/A_rose_by_any_other_name_would_smell_as_sweet). OK, well, maybe we chocolate-fudged that reference a bit but it's still a perfect day for lovers of reliable products from Hirose as today we're looking at the Hirose DF40F and friends (https://www.digikey.com/en/product-highlight/h/hirose/df40f-series-board-to-board-connectors) - diamond-rock solid connectors that mate together perfectly like perfect partners.Ok, I know your number one question, it's how to pronounce Hirose (https://www.youtube.com/watch?v=v4wd9qEZV5A) - is it "high rose"? We got ya, it's "hero say"! And they are definitely heroes when it comes to designing connectors, with well-thought-out components that you probably use all the time. For example, did you know that the ultra-popular u.FL connector (https://www.digikey.com/en/product-highlight/h/hirose/ufl-series) used almost in every RF product is from Hirose (https://en.wikipedia.org/wiki/Hirose_U.FL), patented by them in 1993 (https://patents.google.com/patent/US5180315)? Hirose DF40 connectors have popped up in many developer boards, due to their high density and ease-of-use. The first time we saw them was on the Intel Edison boards (https://en.wikipedia.org/wiki/Intel_Edison), which featured a 70-pin DF40 (https://www.adafruit.com/product/2227) for high speed USB or SDIO interfaces. More recently, the same DF40 family is seen on the popular Raspberry Pi Compute Module 4 (https://www.digikey.com/en/products/detail/raspberry-pi/SC0696/13530919), as dual 100 pin connectors that pass USB, Ethernet, PCIe, eMMC, DVI, DSI and CSI MIPI, and DPI parallel TFT displays. You can check out Shawn Hymel's guide on making an adapter board for the CM4 if you want tips on laying out and soldering DF40's (https://www.digikey.com/en/maker/projects/creating-a-raspberry-pi-compute-module-4-cm4-carrier-board-in-kicad/7812da347e5e409aa28d59ea2aaea490)And looking at the specs for the DF40 series (https://www.hirose.com/product/series/DF40) we see that these connectors are very well 'rounded': they can handle high voltages like 30V AC or DC, high speeds up to 10 Gbps, and fairly high currents 0.3A per pin - just double or triple up pins if you need more current capacity. That means you don't need separate power connectors and can power single board linux computers like the CM4 directly over the same connectors that pass HDMI and PCIe data for reliable and compact connectivity.Compared to 2.54mm or 2mm pitch headers, you don't have to worry about pins getting bent or the high offset height from IDC connectors because the Hirose DF40 series can be as low as 2mm, or as high as 4mm if you need height for component clearance. They're good for at least 30 mating cycles, with grooves to help align for easy mate and de-mate, just make sure to press down flat in the center and lift from two opposite edges so you minimize torque.If you have a submodule or multi-stacked board design and you need a low-profile, high-speed and high-power connector, the Hirose DF40F series of board-to-board connectors (https://www.digikey.com/short/dnr4r5j1) is trusted and reliable by many. I think of Hirose as the "YKK Zippers" of connectors (https://ykkamericas.com/products/zippers/): if you design a $100 board and it fails because of a poorly crafted $1 connector, the quality and reputation of your product is damaged - but if you use a reliable, enjoyable connector that makes good contact each time, the quality and reputation is enhanced! You can order DF40 and DF40F series in a wide series of sizes and configurations from DigiKey (https://www.digikey.com/short/dt70d4t0) all in stock right now and available for immediate shipment, like FTD (https://www.ftd.com/). Book today and your favorite Hirose connectors will ship instantly so that you can get to stacking and snapping by tomorrow afternoon.

It's pettable, programmable, and controllable with your phone or any internet-enabled device, including Alexa or a Philips Hue Bridge. The WLED software is easy to install and set up and comes with dozens of premade animations which can be customized for nearly unlimited color and pattern variations. We're using a Feather ESP32 V2, which connects to your phone or computer via your WiFi network, so everyone in your home can take control and create their own presets and patterns. The software for this project is easy, but there is a fair bit of tricky soldering involved.

we're often working with 'true analog' LED strips (https://www.adafruit.com/search?q=analog+LED), that have 1-3 channels of RGB or White LEDs. and controlling these takes a bit of wiring since they almost always need 12VDC and driver FETs. to make our lives easier, and maybe even some customer's too, here's a STEMMA board (https://www.adafruit.com/product/3893) that can convert a NeoPixel signal using a WS2811F to three AO3406 N-channel FETs (https://www.digikey.com/short/438tn2hb) that are high efficiency and can sink a chunk of current. there's a 3-channel 74LVC3G14 (https://www.digikey.com/short/tqq3tm3m) inverter in between to convert the WS2811 output signal which is open drain, to the NFETs. 5 terminal block ports allow for easy wiring of the +12V, ground, and RGB common-anode channels. unfortunately the WS2811 does not support 4-channel so this won't work for RGBW strips...but there's a lot of times folks need 1 or 3 channels!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

In order to archive double-sided floppies, or deal with Apple Disk ][ drives, we need to create 'fake' index pulses, that's something that lets the software know when the disk surface has rotated 1 time. We have a guide page showing how we support 'hacked' disks using an external optical sensor (https://learn.adafruit.com/flippy-floppy-drive-modification/) but it requires some fiddly wiring. Ideally we could make a little breakout board for the reflective sensor that has a cable for quick installation. We'll want it to be 'right angle', ideally SMT solderable, and it should be a plain logic or analog type output since I2C isn't going to be fast enough to catch transitions.See the chosen part on DigiKey https://www.digikey.com/en/products/detail/vishay-semiconductor-opto-division/TCRT1000/1681165Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is one of a kind - it's the MPS MPM3510A 36 V 1.2 A Step-Down Converter from Monolithic Power Systems (https://www.digikey.com/en/product-highlight/m/mps/mpm3510a-36v-1-2a-step-down-converter). You might be asking yourself, "wait, is this the same Monolith that appeared in Kubrick's 2001 Space Odyssey (https://www.youtube.com/watch?v=ypEaGQb6dJk)?" Technically... no. But, we are talking about a new product that comes to you as a black oblong, and contains technology that will transform and evolve your schematic to the next level of existence.The MPM3510A and friends (https://www.digikey.com/short/5dv839jp) are part of the fully-integrated DC/DC converter family from MPS. These modules contain a step-down chip as well as an inductor - plus maybe a passive or two - to create a tiny buck converter that can take an input from 4.5V to 36V DC and convert it down to 0.8V to 36V, configurable with a resistor divider. Despite it's petite stature, it can source 1.2A, and as its an efficient DC/DC converter, no heatsink is required. With the high integration, you only need two resistors and two capacitors to complete the design.We first spotted these converters on Arduino boards like the Nano Every (https://www.digikey.com/en/products/detail/arduino/ABX00028/10239971) that need to be small and thin. Specifically, that's using the MPM3610A (https://www.digikey.com/en/products/detail/monolithic-power-systems-inc/MPM3610AGQV-Z/5292908), which is an earlier version of the MPM3510 which goes to 21V max instead of 36V. We also have a cute breakout for the MPM3610 with either 3.3V fixed (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4683/12822323) or 5V fixed (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4739/13175530) output. Files for those boards are available on GitHub under an open source license (https://github.com/adafruit/Adafruit-MPM3610-PCB)If you want to quickly integrate the MPM series, check out the downloadable footprints and 3D models available in the EDA Models page (https://www.digikey.com/en/models/7361650). And, even though layout is simple, you should still consult the datasheet to make sure you've got the right setup for the bulk capacitors and power fills, since 1.2A output is a fair amount. One trade-off of having such a small solution is that to get the combined package so small, the inductor has to be low inductance, which means that the PWM frequency of the DC/DC converter is 1-2 MHz. That means you won't be at the top of efficiency...for that you'd have to design a converter with lower frequencies and much bigger inductor.If you need more or less than 1.2A output, or a different range of voltages for inputs or outputs, there's a whole family available of MPM modules, from the diminutive 2mm x 2mm MPM3804 that works only up to 5V and 0.6A (https://www.digikey.com/en/products/detail/monolithic-power-systems-inc/MPM3804GG-Z/7361493) up the chonkin' MPM3686, with a 12x15x14mm body, and 20 Amps output. (https://www.digikey.com/en/products/detail/monolithic-power-systems-inc/MPM3686GRU/5298342)Thankfully, all these chips are yours to use! And, best of all, the MPS MPM3510A 36 V 1.2 A Step-Down Converter (https://www.digikey.com/short/5dv839jp) and friends are all in stock right now for immediate purchase from DigiKey. Order today and it will be shipped instantly, so that you can get your design completed and to market in record time: no worrying over your DC/DC converter design size, efficiency or component selection.
Our cell module we're working with now uses a low-voltage IO core, and when we read the datasheet it helpfully lets us know that we should be using transistors to 'level / current shift' the LED driving outputs. BJT's require a lower voltage to turn on, but they need resistors to help bias - which turns a single component into a 3-piece network. To make our board more compact, let's take a look at 'pre biased' transistors - they come in common packages like SOT-23 and a wide range of resistor configurations!See the chosen part on DigiKey https://www.digikey.com/short/zr9d2j2nVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI has a dash of DSI - it's the new STM32U5 Series microcontroller processors from ST (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stm32u5-series-ultra-low-power-mcus). These bring a wonderful upgrade from the same-old same-old Cortex M4 or M7 with some eye-popping peripherals that will make quick work of any graphics project, but without the weight of a Linux processor overhead.There's lots of chips that purport to have a 'graphics interface' but the moment you sit down to actually use it, you realize that there's very limited SRAM for the graphics display. So you either have to use slow external PSRAM, or you don't get a double-buffer for smooth updates. That's because it's kinda rare to see a microcontroller with more than maybe 1 MB of SRAM. The STM32U5 series is plumped up with up to 3 MBytes of delicious on-chip SRAM, which is perfect for double buffering a 800x480 display with 1.5MB left over, or even double-buffered 720x720 with 1 MB of SRAM left over. Compare that to the STM32H7's max of 1 MB. (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stm32h7-32-bit-high-performance-mcu)That RAM will come in handy because this is one of the first microcontrollers we've seen that has true DSI host support! DSI (https://en.wikipedia.org/wiki/Display_Serial_Interface) is the latest interface standard for connecting to medium-size displays of approximately 480x480 pixels or larger. It's a differential signalling interface which means fewer pins, but the ability to go fast to address fairly large displays. However, because it's differential and high speed, you really need peripheral support - which very few chips have unless you upgrade to microprocessors that drive phones or tablets. Previous to DSI, folks would use SPI displays for up to about 320x240 (https://www.adafruit.com/search?q=spi+display) and 8-bit parallel for displays from 128x640 up to around 480x320 (https://www.adafruit.com/product/1774) and then for displays larger than that - 480x272 or greater - RGB TTL dotclock interface. SPI displays are nice because they have a built in framebuffer - but SPI is slow so you can't drive anything but the smallest screens. Parallel is faster, but still suffers from speed issues. RGB TTL displays have no framebuffer, so you have to write them continuously, and that requires built in RAM or PSRAM and hardware support to keep up with 20-60 FPS updates. Also, ideally, double-buffers to avoid tearing. However, you need a pin for each bit of colors, so easily 30 pins are needed - and even then RGB TTL tends to top out at 1024x600. For 720p or 1080p, most folks would go with HDMI, but you can get these displays with DSI interfaces: and DSI only uses 6-10 pins for 2 to 4 lanes of data plus a clock lane.These new chips are a nice step up from the STM32F7 and H7 series (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stm32h7-32-bit-high-performance-mcu) in that they have the low price, multiple pin package count, with improved RAM and display support. There's also variants with hardware crypto support, high-speed USB, and like we mentioned, with DSI host. There's also a new version of the NeoChrom graphics engine that has vector graphics support, vector font rendering, and JPEG hardware decoding which will allow for video playback with MJPEG (https://blog.st.com/neochrom-gpu-neochromvg-gpu/).We're excited to see DSI interfaces make their way into microcontrollers, and doubly so because the STM32U5 series (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stm32u5-series-ultra-low-power-mcus) is in stock for immediate shipment from DigiKey! We particularly like the feel of the STM32U599 as it has a l'il bit of everything without being top-of-the-line, and it comes in QFP (https://www.digikey.com/short/15vv8m9r) for easy integration no matter what fabrication setup you've got. Order some STM32's from DigiKey today and they will ship faster than you can render a bouncing ball, making its way to you by tomorrow afternoon.Check out the ST video https://www.youtube.com/watch?v=8xi-eagiGtU
A few weeks ago we showed off our High Voltage UPDI programmer prototype (https://www.youtube.com/watch?v=YYXufxPQAPU). We're still working on that...our Low Voltage one is available in the shop now (https://www.adafruit.com/product/5879). We got a request for us to stock a general-purpose 12v-capable analog switch like the one we used in the HV design. Note this sounds a lot like a previous TGS - but that one was for a quad analog switch and we didn't need to handle voltages above 5V. (https://blog.adafruit.com/2023/05/08/the-great-search-analog-switch-chips-and-multiplexers-thegreatsearch-digikey-digikey/) So, let's go hunting at DigiKey for a low cost analog SPDT switch that is higher-voltage capable, we'll also poke around the ADI search system to augment our search. We'll also chat about CMOS vs TTL input levels, to make sure we can easily use the part we find.See the chosen part on DigiKey https://www.digikey.com/short/48894j2bVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

OK, after a long hiatus, the ESP32 Itsy Bitsy prototypes are built and ready for testing! We first designed this board Feb 20, 2020 - and it's been waiting oh so patiently for its turn. The ESP32 Pico module packs 8 MB of flash and 2 MB of PSRAM. Despite its small size this board can handle fairly complex programs. This board is very small but has lots of pins, with a USB-serial converter, NeoPixel, reset and user button, Stemma QT connector, and a 5V-logic output specifically for driving NeoPixels. to do my final 'all in one' test we're reading temperature and humidity from an I2C sensor, sending it to IO, then reading back the onboard NeoPixel color from the dashboard. It's an excellent way to make sure the whole thing is working the way we like. Last up, we'll do a low-power test, and then it'll be ready for fabrication!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#espressif #esp32 #adafruit #ItsyBitsy
All of our ItsyBitsy boards use Micro USB connectors, so despite USB Type C being all the fashion, we're going to continue with sourcing a Micro USB connector for the ESP32 board we just designed. We've learned a lot from years of using Micro USB connectors on the pick and place line. All SMT is a big no-no - go with thru-hole mounting holes for good mechanical security and allow for big pads for lots of solder! Join us as we find a few good options for folks who want to continue using Micro-B connectors in their designs.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is a cool cubic camera - it's the Analog Devices Inc. (nee Maxim Integrated) MAXREFDES178 (https://www.digikey.com/short/t4052tpj), an all-in-one vision eval board for the MAX78000 (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/MAX78000EXG/13155097). The MAX78000 is a specifically customized ARM Cortex M4 microcontroller that has a Convolution Neural Network sub-circuit. This means that it's really good at doing the kind of mathematical calculations required to do vision or audio-based machine learning inferences without the need for a heavy-duty processor like in a Single Board Computer or Internet co-processing. This makes it great for stand-alone smart camera applications - which is why the MAXREFDES178 (https://www.digikey.com/short/t4052tpj) is an excellent eval board that might even be able to be integrated in your final design.The MAXREFDES178 camera kit (https://www.digikey.com/short/t4052tpj) comes as a small hackable cube with two MAX78000s - one for video and one for audio processing. A 1.5" 240x240 resolution TFT with capacitive touchscreen, OVM7692 camera module (https://www.digikey.com/en/products/detail/omnivision-technologies-inc/OVM7692-RAAA/3190565), I2S Codec, I2S microphone, 5 buttons, Lipoly Battery, USB Type C with battery charging, and microSD card slot that can be used to load 'Apps' onto the processors. There's also a cute SWD programmer dongle that plugs into the USB so you can do full programming and step debugging of your own application.The strength of the MAXREFDES is that it demonstrates the audio and video inferencing that normally would take a Raspberry Pi-like SBC computer or an online connection for the heavy computation. But, since it's done on-chip, the power draw is much much less and the startup time is nearly instant. This makes it great for portable, battery, or even solar / power-harvesting applications (https://www.youtube.com/watch?v=TvuLv13EGlM)As with most AI products, the biggest challenge for starting out is how to train the model that will be used for inferencing. The MAXREFDES178 comes with a basic voice-detection model that covers about 20 words, or about 10 celebrity faces. However, unless you happen to be designing a paparazzi product you'll need to create the model that detects exactly what you want and then load that into the MAX78000's CNN memory. Analog Devices has a video series (https://www.analog.com/en/education/education-library/videos/video-series/understanding-artificial-intelligence.html) and GitHub documentation repo (https://github.com/MaximIntegratedAI/MaximAI_Documentation) that goes through the process of how to do the training: you can use the popular PyTorch or TensorFlow Lite environments. Note that since the CNN is in hardware, not 'bitbanged' on the main core, you do not have to use TF Lite for Microcontrollers (https://www.tensorflow.org/lite/microcontrollers) - although you could probably run the TFLiteMicro codebase if you wanted, on the MAX78000, it just wouldn't get any hardware acceleration. Creating the model will require collecting a ton of data, image or voice, and then training using a CUDA-powered desktop or cloud computer.If you're interested in edge AI development (https://www.analog.com/en/thought-leadership/the-dream-of-edge-ai.html), the MAX78000 is an excellent chip to use with a familiar ARM M4 core and tons of peripherals to support any external sensors or devices needed - no co-processor needed! There's even a Feather board available (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/MAX78000FTHR/13549063), but for quick audio/video development, the MAXREFDES178 camera kit (https://www.digikey.com/short/t4052tpj) works right out of the box and it's in stock right now at DigiKey for immediate shipment! Order today and it'll ship immediately so you'll be convolving and neuralling by tomorrow afternoon.See more in the video here https://www.youtube.com/watch?v=7Toaz-0vdIE

For our NeoPixel signal to analog LED converter design, we need to convert 3 open drain PWM outputs to drive N-channel sinking MOSFETS. To do that we'll need to invert the signal - but we don't have a ton of space. So let's source a triple-NOT gate that has push-pull output, and can run from 3 or 5V logic. We also want it to be small, but not TOO small!See the chosen part on DigiKey - https://www.digikey.com/short/tmdnp712Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
Historically, we've tested and programmed our Feather ESP8266 (https://www.adafruit.com/product/2821) and ESP32 boards (https://www.adafruit.com/product/3405) from a Raspberry Pi. We'd connect over USB and run esptool.py, which works fine but has more things that can go wrong: power flickering, SD card failures, etc. It's better to fully program it with a Pico RP2040 brain board. We can do that now because TinyUSB has support for USB CDC Serial chips (https://github.com/adafruit/Adafruit_TinyUSB_Arduino/tree/master/examples/DualRole/CDC/serial_host_bridge) like the FT232, CP210x, and WCH9102! We upload the stub and test firmware, then listen on the CDC for the self-test output. It works really fast and is much easier to manage.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #rp2040 #electronics

This week's EYE ON NPI is a part of a balanced breakfast, wait no we mean a balanced battery pack! It's STMicroelectronics' AEK-POW-BMS63EN Battery Management System Module (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/aek-pow-bms63en-battery-management-system-module) featuring the L9963E automotive multicell battery monitoring and balancing IC (https://www.digikey.com/short/q4jw21t1). This chip brings automotive-grade battery management to any product designer, at a great price, so you can keep your batteries monitored and balanced for a safe and long usage life.All cars have batteries, and if you have a internal combustion engine car, you're probably familiar with the 12V lead acid battery (https://www.diehard.com/vehicle-batteries/) that needs replacing every 5-10 years, these batteries do not power the moving car itself, just the lights, stereo, electrical system and the spark plugs needed to get the engine running. These batteries are pretty simple, there are two big lugs, a ground and a +12V, inside is 6 series Lead Acid cells, of 2V nominal each. The battery is charged by the engine, and while you don't want to over or under-charge lead-acid batteries are pretty forgiving. In EV electric vehicles, the batteries have to have much higher energy density (https://en.wikipedia.org/wiki/Energy_density) so they use Lithium Ion cells, often '18650' cylindrical cells. These are connected in long series strings, to provide high voltages and then parallelized to give high currents. The same batteries are also used in e-scooters, e-skateboards and other micro-mobility devices, they're very low cost, and packs are easy to make. BUT, Lithium-based batteries, as part of the high energy density, have a lower life and are more sensitive to charge and discharge cycles. One of the things we have to worry about is keeping the batteries balanced. That means that we have to monitor each cell in the string carefully to make sure the state of charge matches the rest. The ST L9963E does this in two ways (https://www.digikey.com/short/q4jw21t1), first is per-cell voltage monitoring, and also per-string current monitoring. Once each cell's state of charge is known, internal or external FETs can be used to shunt current from each cell during the charge cycle, with the goal of bringing the cells back into balance at the cost of charge rate because now we're going to charge every cell as slow as the 'worst' cell. However, this keeps the system safe from overcharging, and is a lot less expensive/complex than active balancing.Since this chip is fairly complex, having a ready-to-go eval board that is already set up with the isolated SPI interface is a worthy investment. You can get started fast and just integrate the AEK-POW-BMS63EN directly into your prototype while you work out your battery management system. The board has USB-like ports on either side but these are actually two-wire isolated SPI, which protects your low-voltage microcontroller or computer from possibly getting zapped by the 48V+ battery. You can use USB A-A cables, since the pinout will work fine, but just be aware you can't plug it into your computer. To connect the opposite side to your micro, you'll also need to pick up a de-isolator AEK-COM-ISOSPI1 (https://www.digikey.com/en/products/detail/stmicroelectronics/AEK-COM-ISOSPI1/19721659). Finally you'll need to write the SPI interface library for managing the battery. We found one published L9963E library that might get you started (https://github.com/squadracorsepolito/L9963E_lib) - written by the Squadra Corse student Formula SAE teams. (https://squadracorsepolito.com/)If you have a project with large batteries and you want an automotive-grade battery management system, the L9963E automotive multicell battery monitoring and balancing IC (https://www.digikey.com/short/q4jw21t1) and matching Evaluation Board (https://www.digikey.com/short/c00jq224) will make it easy to get started. And best of all, both are in stock right now for purchase at DigiKey! Place your order today and your order will ship in moments, so you can get started with battery management by tomorrow afternoon.

2021 and 2022 were rough years for IMUs - they were quickly sold out everywhere and remained unavailable for most of the years. We're trying to get the last of the 'part shortage' designs back into stock. This week we're doing the CLUE and Feather sense - both sensor-packed designs! We used a 'pair' of chips, the LSM6DS33 plus the LIS3MDL. We previously found an alternative to the LIS3MDL (https://blog.adafruit.com/2022/03/15/the-great-search-triple-axis-magnetometer-replacement-for-lis3mdl-thegreatsearch-digikey-adafruit/). This week we're going to look for a good alternative for the LSM6DS33, with similar or better performance!

This week's EYE ON NPI is the 'top' pick for the 'top' of the year: our first NPI choice of 2024 is Microchip's MPLAB PICkit 5 in-circuit debugger! (https://www.digikey.com/en/product-highlight/m/microchip-technology/mplab-pickit-5-in-circuit-debugger) This is the latest all-in-one toolkit for programming and debugging any chip available from Microchip, and believe us when we say there's a lot of chips available with different program/debug systems that need supporting! MCP purchased Atmel in 2016 (https://en.wikipedia.org/wiki/Atmel#Acquisition_by_Microchip_Technology) and since then has been slowly integrating Atmel chips such as AVR/SAM/ATtiny/ATmega into the MCP toolchains and workflows. For that reason, the PICkit is powered by a advanced 300MHz ATSAME70 chip, which provides ICSP, MIPS EJTAG, SWD, AVR JTAG, AVR UPDI & PDI, AVR ISP, TPI and debugWire. To do that, there's an 8-pin 0.1" socket connector on the end, you're expected to select the right grouping of pins for whatever chip you're targeting. You can make a custom wire harness, but we think you might be best off also picking up the AC102015 Adapter Kit (https://www.digikey.com/short/tr3bhf52) which comes with every popular cable adapter.OK since we are talking about a PICkit, it's not surprising that all of the PIC microcontrollers are supported - these use an "ICSP" programming method (https://ww1.microchip.com/downloads/en/DeviceDoc/30277d.pdf) with power, ground, two data pins and a VPP high-voltage line for FLASH reprogramming. We still use this interface to program chips like the PIC12 on the pixie 3W LED driver (https://www.adafruit.com/product/2741) This interface is ancient and will program basically every PIC12, PIC16 and beyond - Microchip was thankfully very consistent on this interface.Of course, you probably are also using Cortex-based chips: these use JTAG and SWD (https://developer.arm.com/documentation/101636/latest/Debug-and-Trace/JTAG-SWD-Interface). Those are also supported! Since this is a programmer plug debugger, you can also connect SWO for trace. The same JTAG/SWD interface is used for programming and debug.Supporting AVRs is also included, and for less than the price of the ATMEL ICE (https://www.digikey.com/en/products/detail/microchip-technology/ATATMEL-ICE-BASIC/4753381) you get all the same chips supported. Aaaand there's a lot more required to support the whole AVR family. For example, many small older ATtiny chips, you'll be using TPI (https://ww1.microchip.com/downloads/en/Appnotes/doc8373.pdf) because you only have a couple pins available. On newer ATtiny chips (and maybe even ATmegas) the async-uart-single-wire UPDI interface (https://onlinedocs.microchip.com/pr/GUID-DDB0017E-84E3-4E77-AAE9-7AC4290E5E8B-en-US-4/index.html?GUID-9B349315-2842-4189-B88C-49F4E1055D7F) is becoming more popular, that's available with an optional high-voltage mode which would let you use the UPDI pin as a reset pin as well. Standard ISP is supported for programming those Arduino compatibles you've got in a drawer, and there's also debugWire support! This was a one-wire debugging interface for AVRs that we never got to try out, so maybe now I will be able to! Don't forget you'll want that AC102105 Adapter Kit (https://www.digikey.com/short/tr3bhf52) to make wiring to various dev boards easier.The most interesting new features that we haven't seen on other programmers is the 'Programmer To Go' field-reprogramming capability which allows burning full programming configuration files off of a micro SD card to any target, it can even be powered from the target if needed! Use MPLAB X to create the file that contains all the fuses and data to be transferred. Save to any FAT32 formatted uSD card, then on site you can press the button to re-program the device. The indicator LED strip will give some visual feedback so you know what it's up to. If you want more control over the setup, use the iOS or Android app to pair over Bluetooth, then select which file and also get error reports in readable text.For any development needs you've got with PIC or AVR or SAM chips, the Microchip MPLAB PICkit 5 in-circuit debugger (https://www.digikey.com/short/fznt5mnh) is going to be the best and most-supported tool - being an official Microchip product means you don't have to worry about future chip support or historic chip maintenance. And best of all it is in stock right now at DigiKey for under $100.(https://www.digikey.com/short/fznt5mnh) Add one to your cart and it will ship immediately so you can be PIC'ing, debugWire'ing and UPDI'ing by tomorrow afternoon.
The Adafruit TS3USB30 1 to 2 USB Switch is a nifty breakout board for the TI TS3USB30 (https://www.digikey.com/en/products/detail/texas-instruments/TS3USB30ERSWR/2092506) that will let you connect one of two USB devices to a single port, handy when you have multiple chips that you may want to communicate over USB but you don't want a hub. Our new breakout will connect one or the other. We designed for USB to handle high bandwidth USB 2.0 connections of 480 Mbps. But before we put it into stock, we gotta test it! This tester has two different USB peripherals connected: a CP2102 on a Metro Mini and an FT232RL in a console cable. We're using the Metro RP2040's bit-banging USB host stack (https://learn.adafruit.com/adafruit-feather-rp2040-with-usb-type-a-host) to test enumeration: when the RP2040 detects two different PIDs based on the switching pin, we know the board is good!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #usb #ts3usb30

We just finished revising our resistive 3.5" TFT FeatherWing (https://www.adafruit.com/product/3651) - it's been out of stock due to part shortages and needed a complete redesign, and then found this ancient box of 3.5" capacitive touch screens (https://www.adafruit.com/product/5846)...so with a bit of razzle-dazzle-CAD-o-matic we put together a 3.5" TFT Wing with capacitive touch support! This screen is nice in that it has true multi-touch capabilities. The 3.5" 320x480 capacitive touch FeatherWing will make an excellent Wing display that only needs SPI + I2C to interface. We only need to push down the bottom edge so that it can 'clear' the FT5336, which is on the FPC.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #feather #display
Like the CLUE board, another one of the boards that has been out of stock for a looooooong time is the Feather nRF52840 (https://www.adafruit.com/product/4516) - so many of the components got discontinued or were unavailable on this board it took till now to get enough parts to put it back in stock! The biggest one is the LSM6DS33 (https://www.adafruit.com/product/4480) is discontinued, so we replaced it with the LSM6DS3TRC (https://www.adafruit.com/product/4503) - the tester code required some updating so we also swapped it from using a Teensy 3.6, now entirely discontinued, to our Pico Brains. The complete program and test take about 30 seconds. We're excited to restock this prodigal board!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
We previously made a jerry-rigged USB Host Wing (https://www.adafruit.com/product/5858) tester based on an ESP32-S2 TFT board (https://www.adafruit.com/product/5300) and a pogo-pin (https://www.adafruit.com/product/394) filled Feather Doubler (https://www.adafruit.com/product/2890) - but for final testing of hundreds of boards off a panel, a nice custom-made PCB is better. This one uses a Metro M0 since our SAMD21 board support package has TinyUSB support - so we can verify if we enumerate the connected USB peripheral. If a vid/pid is found, we're good to go, and beep and blink to indicate the test has passed.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #diy #electronics

we designed this TPS61040 board (https://www.digikey.com/en/products/detail/texas-instruments/TPS61040DBVR/454263) like a year ago and messed up the BOM on the first run so that it had 100 ohm resistors instead of 100K for the voltage-setting divider. woops! and then it sorta sat on the "to fix" pile for a long time. but...new year, new us! time to fix and get back into production. the tester is a Metro 328 (https://www.adafruit.com/product/50), it turns on and off a 120 ohm load to verify the 12V output can source the current specified. a resistor divider goes from the output to a analog input. beep! its good to go :)Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

The biggest one is the LSM6DS33 (https://www.adafruit.com/product/4480) is fully discontinued, so we replaced it with the LSM6DS3TRC (https://www.adafruit.com/product/4503) - the tester code required some updating but otherwise this is good to go!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

this prototype board allows folks to use many Grove devices with Feather boards! it fits nicely on top and has 3 Analog/Digital connectors, 1 UART connector and 2 I2C connectors. Not a ton, but enough to get many small projects going. we even managed to fit a vertical Stemma QT port on the end for another I2C connection. we think this board will be handy for bridging two great standards!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is an EYE ON SPI! We're going looooooooong with the Analog Devices LTC4332 Point-to-Point Rugged SPI Extender (https://www.digikey.com/en/product-highlight/a/analog-devices/ltc4332-point-to-point-rugged-spi-extender) which lets you take what normally would be a short PCB-trace connection to SPI devices and have them up to 1200 meters away - that's over 12 football fields (https://en.wikipedia.org/wiki/American_football_field) using a differential link protocol that can run on common CAT-6 cabling. This means you can have have super long SPI connections for distributed node communications that need more bandwidth than I2C but don't need the complexity of an Ethernet controller.ADI's LTC4332 is a point-to-point rugged SPI extender designed for operation in high-noise industrial environments over long distances. Using a ±60 V fault-protected differential transceiver, the LTC4332 can transmit SPI data, including an interrupt signal, up to 2 MHz over two twisted pair cables. The extended common mode range and high common mode rejection on the differential link provide tolerance to large ground differences between nodes.We're excited about the LTC4332 (https://www.digikey.com/short/88rpbrfh) because we know that Linear Tech-designed hardware is really good quality and the specifications are 'real' rather than optimistic. We've used a similar-family chip for I2C, the LTC4311 (https://www.adafruit.com/product/4756) which is an active terminator - but found it definitely will let you extend I2C to 100 feet with no issue and no code required. The LTC4332 (https://www.digikey.com/short/88rpbrfh) is, likewise, a 'transparent' bridge chip that converts a 4-wire SPI connection, with 3 chip selects and one IRQ line to a differential protocol that will work nicely with common Ethernet cables (https://en.wikipedia.org/wiki/Category_6_cable). One nice detail is that you can use any of the 4 common SPI modes for polarity and SCK latch-direction (https://en.wikipedia.org/wiki/Serial_Peripheral_Interface#Mode_numbers).The same chip is used on both sides of the controller and peripheral connection, simply set the REMOTE pin to high or low to determine which side is which. Then make sure the SPEED pins are set up the same, as they will determine the expected max-clock speed. Wire up the two differential pairs, when the connection is good, the LINK pin will drop low which you can use like an Ethernet link light. For more advanced configuration you can connect to the internal chip to read fault and status bytes. However, it looks like you don't have to unless you want more control: the chip will function transparently even without firmware register configs.One thing to watch out for, while controller-to-peripheral data is sent instantaneously, reading data is delayed by one byte because it has to read the full byte in and then transfer it over the differential connection. So if you're using it to read from a remote sensor or driver, make sure to 'toss' the first byte and read an extra byte at the end!If you're looking to go long with a simple solution to remote SPI communication, the Analog Devices LTC4332 Point-to-Point Rugged SPI Extender is an excellent choice (https://www.digikey.com/short/7zcd7vc5), don't forget you'll need two for each remove device. There's also a compact dev board available called DC2799A (https://www.digikey.com/short/qbn5397v) that has input and output sides for instant testing. The LTC4332 (https://www.digikey.com/short/7zcd7vc5) is in stock right now for immediate shipment from DigiKey - order today and you'll be able to take your SPI devices to the next level - like literally to the new few floors up - by tomorrow afternoon!

We go through literally millions of our 'jellybean' 10uF caps - more specifically 10uF 16V 0805 X5R 10% ceramic capacitors. There can be dozens on every board we make, they're great for an extra bulk capacitor, alongside your 1uF or 0.1uF higher-frequency friends. They're also a ton smaller than electrolytic caps (https://blog.adafruit.com/2021/02/09/the-great-search-electrolytic-capacitors-thegreatsearch-digikey-adafruit-digikey-adafruit/)! We'll look for some options you can use, my recommended voltage ratings and package sizes, what 'X5R' and 'Y5V' means, and when you should NOT use MLCCs!See the chosen part on DigiKey https://www.digikey.com/short/crqdtcj5

Honk! Honk! This week's EYE ON NPI is jazzy, be-dazzly, and sure-to-get-your-attention-y: it's CUI Devices' Illuminated Buzzers (https://www.digikey.com/en/product-highlight/c/cui-devices/illuminated-buzzers), a set of incredibly loud audio indicators that also have built-in LEDs that light up! What a great way to quickly turn an existing design into an accessible, multi-sensory alarm system without having to redesign the enclosure or PCB.These are very loud buzzers, good for industrial equipment - with a range of 83 to 100 dB, loud enough to alert in an office or factory. The LEDs are also nice and bright, for good indoor visibility.There are three sizes/shapes available. The smallest is the CLI-1375 PCB-mount design (https://www.digikey.com/short/m4zc8d3z) with 13mm diameter body, which is the same shape as many PC-pin buzzers. When powered with 6 to 15V it emits a piercing 83 dB, 4 KHz square wave and the inner LEDs light up. You can get 4 different shades of translucent plastic: red, yellow, green and blue. Note you aren't expected to provide a square wave: there's an internal wave generator. There's two versions for the CLI-1375 buzzer, one has a steady tone and LED light, the other has 1 Hz-ish modulation for both the LEDs and beep.The CLI-3224 medium size is 32mm diameter (https://www.digikey.com/short/1zwrvdf1) is a nice panel mount version with 8 SMT LEDs, four color options, and a shape that is evocative of arcade buttons. This version has spade connectors for power, and can be powered from 3 to 15 VDC. It will emit a 95 dB 3 KHz tone at the 12V rated power. Unlike the PCB-mount design, this one doesn't have a 'pulsing' version.Finally, the CLI-3623 large size is 36mm diameter (https://www.digikey.com/short/4tnpp4fz) and is also panel mount, but with a flatter top. It also has 8 SMT LEDs, and four colors. Like the CLI-3224, 3-15VDC power is provided via spade lugs. Volume is also 95 dB at 12VDC, the tone frequency is 3.5KHz.All 16 versions of 4 types, and 4 colors of CUI Devices' Illuminated Buzzers (https://www.digikey.com/short/b790m8vw) are in stock right now at DigiKey for immediate shipment. So if you order today, DigiKey will get the alarm to get your order out the door ASAP, and you can get beepy and blinky instantly with any configuration you desire by tomorrow afternoon.

Full teardown and upgrade tutorial: https://adafruit-playground.com/u/firepixie/pages/electric-fireplace-teardown-and-upgrade-with-wledNew guide showing the inner workings of an LED electric fireplace. This fireplace is a very cool piece of art that came with a VERY annoying beep. My tutorial shows how to remove the beep and also upgrade the lower RGB LED strip with animated lights. Now the bottom strip animates to look like embers or rainbows or whatever else I desire. I also detail how to hook the new light strip up to the original IR Remote that came with the fireplace so I can control it with one remote.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
Thin 30 AWG 'wire wrap' wire can be used to solder to fine pitch pins and parts for repairs or debugging. We always recommend every engineer have a roll on hand - even though it is not good for use with a breadboard, it's essential for repairing or hacking PCBs. Originally these were used for point-to-point circuit creation (https://en.wikipedia.org/wiki/Wire_wrap) with a wire-wrapping tool (https://www.digikey.com/en/products/detail/jonard-tools/WSU-30M/5986) - before the cost of PCBs plummeted (https://www.digikey.com/en/resources/dkred). Sometimes called Kynar wire, this is stocked at DigiKey - you might think "OK why is this a Great Search when you can just type wire wrap into the search box?" Well, watch to learn about a few options you may not have known about!See the chosen part on DigiKey https://www.digikey.com/short/bjwtnph7Don't forget, #DigiWish is happening right now on social media (https://twitter.com/digikey/status/1731349619836133553) Make sure to pick out something in stock from the DigiKey catalog and post up up every day - one person is selected each day to get their wish as a gift!

This week's EYE ON NPI is a compact and capable analog-to-digital converter, it's the Microchip MCP3421 18-bit, 240 SPS, single-channel ADC (https://www.digikey.com/en/product-highlight/m/microchip-technology/mcp3421-analog-to-digital-converter). This SOT-23-6 part is simple, inexpensive, and easy to use with an I2C interface that can run up to a 3.4MHz clock rate. Being able to power it from 2.7V to 5V makes it an easy-to-integrate component whenever you need an ADC that has differential inputs, adjustable gain, and a built in precision/low-drift reference voltage.One of the trade-offs with getting 18-bit precision is that the ADC is not going to be very fast: you can configure the chip to do a faster 12-bit conversion at 240 SPS, but at 18-bits, it slows down to 3.5 SPS. That's because the way a sigma-delta ADC (https://en.wikipedia.org/wiki/Delta-sigma_modulation) works, it 'guesses' the analog voltage and uses a comparator to determine whether the input is higher or lower. Each 'guess' takes an extra step, and thus halves the throughput, so 12-bit is 240 SPS, and 14-bit is 1/4 (2-bit) slower, 60 SPS. Ditto 16-bit is 1/4 slower, 15 SPS, and finally 18-bit is 3.75 SPS. However, sigma-delta ADCs are inexpensive, so as long as you don't need high speeds there's no reason to spec a faster and more expensive part!The MCP3421 is already set up for differential inputs, which means that you can read positive or negative differences between the two inputs, as long as both signals are between 0 and 2.048V. This means it's not going to be great for reading stuff like potentiometers, where you have a single-end reading referenced to ground, and you want to read the full range from 0 to Vcc. It is great, however, for reading sensors like strain gauges, pressure sensors, or thermocouples.The I2C interface for the MCP3421 is simple and well documented: there's a command byte that can be written directly to set continuous or one-shot, gain from 1x to 8x and the ADC bit depth. Then, the current data can be read directly, with the status/'command' byte following. Since the ADC is differential, note that the data will come out as binary 1's complement for easy casting to a signed 16 or 24 bit variable. Since there's no address selection pin, you can determine which I2C the device responds to by purchasing a part code variant. For example, A0 is address 0x68, A1 is 0x69, etc.We used ChatGPT to quickly put together an Arduino-compatible library (https://chat.openai.com/share/76252459-50e5-4cd2-8edf-08bf3cc1c438) in about an hour and it pretty much worked right out of the box minus a few typos. The final, tested library code is available here (https://github.com/adafruit/Adafruit_MCP3421). We also spun up a quick prototype PCB for the MCP3421 (https://twitter.com/adafruit/status/1650909789591945248) and it works very nicely, with a terminal block for the differential input, and Stemma QT ports to quickly plug into a variety of dev boards.If you're on the look-out for a well-designed high precision ADC to integrate into your next design, the Microchip MCP3421 18-bit, 240 SPS, single-channel ADC (https://www.digikey.com/short/5htnqnw8) is an easy win. And, best of all, it's in stock right now for immediate shipment from Digikey. Order an MCP3421 today (https://www.digikey.com/short/5htnqnw8) and you'll be convertin' by tomorrow afternoon!

This week we're looking for a high-reliability micro SD card - you can get inexpensive SD cards for basic device usage anywhere, but if you need one that can handle many years of 24/7 data writes, or for use in industrial temperature ranges, it's best to get a card that has a datasheet and usage guarantees!

This week's EYE ON NPI has us pitter-pattering on our tippy-toes, it's the newest and bestest stepper motor driver we've seen, the Analog Devices' TMC5240 Stepper Motor Controller and Driver IC (https://www.digikey.com/short/rt0zpt4v) from the Trinamic division at ADI! Trinamic is famous for their stepper motor driver chips, which we see often in 3D printers (https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/trams.html), XY gantries and other robots that need fast motion control.Stepper motors are commonly used when we need continuous rotation for linear movement through a rack and pinion. We've got huge steppers in our pick and place machine, and most makers are going to be familiar with them in CNC devices like laser cutters, 3D printers or milling machines (https://www.digikey.com/en/product-highlight/b/bantam-tools/desktop-pcb-milling-machine) - servos will be controlling the X, Y and Z axes as well as any extruder. And if you have one of these devices you know they can be loud and slow: in order to get good precision from a stepper we need to micro-step, so that instead of a standard 200 steps per rotation, we get 16200 or 256200 (https://www.analog.com/en/products/landing-pages/001/optimizing-stepper-motors-microstepping.html). Microstepping gets us that beautiful precision, but adds a ton of noise because now there's a PWM signal that is vibrating the motor (https://www.analog.com/en/products/landing-pages/001/secret-silent-stepper-motor-control.html). That's where Trinamic's StealthChop2 secret sauce comes in:The StealthChop chopper modulates the current based on the PWM duty cycle, resulting in a perfect current sinewave with straight crossing of the zero-current level. The constant PWM frequency minimizes current ripple and, by extension, any Eddy current that may be found in the stator, reducing power loss, and increasing efficiency. The StealthChop chopper also removes variations of the chopper frequency, or frequency jitter, so that only the commanded variations remain. Thus, at a 50% PWM duty cycle, the current is actually zero. The result of all this is silent stepper motor operation at a standstill and at low to moderate speeds.We've covered Trinamic's TMC2226 stepper driver before on EYE ON NPI (https://blog.adafruit.com/2020/06/18/eye-on-npi-tmc2226-sa-ultra-silent-stepper-motor-driver-eyeonnpi-digikey-adafruit-digikey-adafruit-trinamic_mc/) and that chip mimic'd the common configuration for stepper motor drivers: set the microsteps with GPIO and then use a DIRection and STEP pin. That makes it easy for integration with any hardware, you just need some GPIO pins, but it means that you have to do the motion control yourself. And, once you have 2 or 3 motors, motion control code can get really complicated: you have to tune and configure ramp ups from idle to fast run, and back down so there isn't any jerky motion. What's really cool is that the TMC5240 has built-in motion-control! You set some configurations and then can tell it what position or velocity to achieve, and the microstepping is done for you. It even handles encoder reading, mechanical stall detection, and end-stop switch interrupts for you so you don't slam into the side of the machine by accident.To do this, the TMC5240 has a full register and command set, that can be controlled with SPI or UART - with UART there is node addressing required, but perhaps this is easier to integrate with low-pin microcomputers. For both, commands are sent for configuring everything from stall current, to motion control, to individual steps to temperature reads. Speaking of which: the TMC5240 come in two packages: QFN and TSSOP. TSSOP has a big thermal pad at the bottom for better dissipation, QFN is smaller. With either, use plenty of vias, a 4-layer design with dedicated 2 oz copper ground planes to keep the motor driver cool: these can handle 5-36V at up to 2A per leg, so they are throwing a lot of current around.You can pick up bare TMC5240 chips (https://www.digikey.com/short/vhvtnjbw), basic breakout boards (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/TMC5240-BOB/21292888) and eval boards (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/TMC5240-EVAL/17878664). Since you have to use the SPI/UART protocol to communicate, we recommend checkout out the pyTrinamic library (https://github.com/trinamic/PyTrinamic) which has added support to the TMC5240 (https://github.com/trinamic/PyTrinamic/blob/master/pytrinamic/ic/TMC5240.py) so you can hit the ground running / stepping. Order up some of these silent stepper drivers today and you'll get them in hand by tomorrow afternoon, you'll save tons of time on your next robotic or mechatronic project thanks to the tons of built-in capabilities on the TMC5240!

This week's Great Search comes from a social media request. Daniel's 3D printer board lost one of its connectors used to connect to the Z stepper motor, at it looks like two of the legs snapped off so it isn't easy to solder back in place.It's SMT, 4-pin, but of unknown make and pitch. Let's find out what connector it is and whether we can pick up a few replacements on DigiKey!

The wonderful world of Python on hardware! Episode 255 (November 15, 2023). This is our weekly Python video highlights! Ladyada and PT review the Python on hardware news of the week.The news comes from the Python community, Discord, Adafruit communities and more.

This week's EYE ON NPI is in a class of its own, it's Richtek's RT9120S Series Class-D Audio Amplifier with DRC Control,(https://www.digikey.com/en/product-highlight/r/richtek/rt9120s-class-d-audio-amplifier) a powerful amplifier with a wide operating voltage range, high efficiency, high wattage and many supported input formatsWe love I2S audio amplifiers here, they're a huge step up from PWM + analog amplifiers (https://en.wikipedia.org/wiki/Pulse-width_modulation) in that you will get much higher audio quality due to having true analog output and the DAC being tuned for 16, 24 or 32-bit audio. Most simple PWM is maybe 8 or 10 bits! As long as your microcontroller or microcomputer has I2S output support, you can use 3 or 4 pins to generate a bitstream of audio. For example, our Stereo Bonnet (https://www.digikey.com/en/products/detail/adafruit-industries-llc/3346/6573323) adds two single-channel I2S amplifiers to the Raspberry Pi so that it can drive 3 Watt speakers. But what if you need more MOAR power? This is where this I2S amp will shine: it can handle up to 30W per channel, stereo, and best of all it does not require an MCLK input signal (https://en.wikipedia.org/wiki/I%C2%B2S) so it will work great on Raspberry Pi computers of any size - although of course it will work on other microcontrollers and microcomputers as well. Let's take a look and some of the features we like in this chip.First thing to note is that there are a few options in the RT9120 family (https://www.richtek.com/~/media/AN%20PDF/SG017_2022.pdf): the RT9120 is the original, the RT9120S is an upgrade - it can now support 30W instead of 20W thanks to an RDS(on) as low as 90 mΩ and has 94% efficiency over 92%. It does seem to be pin compatible, so if you're using the non-S version this ought to be pin-compatible for an upgrade. This amp is Class D, which means if you're used to class AB amps that require massive heat-sinking, you'll be please to know you can likely get away without requiring a heat-sink - although you'll probably want a big back ground plane and 2 oz copper to help dissipate via the thermal-package ground pad. The trade off is you will need some passive components on the output of the amplifier, because it generates a high frequency - up to 1.5MHz - PWM signal that needs to be filtered down to 10-20KHz. It looks like this amp can use simple ferrite bead + capacitor outputs, but for the best EMI filtering and sound, a 10uH + 0.47uF capacitor is needed for each 'leg' of output.As this is a powerful amp, and since people will want to play it loud, and you'll want to avoid nasty clipping, the RT9120 also features Dynamic Range Compression (https://en.wikipedia.org/wiki/Dynamic_range_compression) which will slowly turn down the gain as the signal gets louder, so that you don't get square wave distortion.Lastly, you will need to control the chip over I2C, it isn't free-running. However, this means you can enable filters, change the Class D frequency, adjust the gain digitally instead of reducing the signal depth, and get an error output report to know if there's a short or open on the speakers, or missing I2S signal lines. However, if you're using a Linux-based system there's already a Richtek-authored kernel driver you can use.(https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/sound/soc/codecs/rt9120.c)Sounds good? I think so! And the fact that the Richtek RT9120S Series Class-D Audio Amplifier with DRC Control is in stock right now at DigiKey for immediate shipment at a very nice price (https://www.digikey.com/short/wqddcrqj) is music to my ears. You can also pick up an eval board for a very reasonable price (https://www.digikey.com/en/products/detail/richtek-usa-inc/EVB-RT9120SGQV/19914630) which will get you started quickly, particularly if you need to implement an I2C driver. Order today and DigiKey will ship your order instantly, you will be able to start adding booming quality sound to your design by tomorrow afternoon.

We have designed a breakout that lets folks use either 8-bit or SPI addressing mode - similar to our 3.5" resistive breakout (https://www.adafruit.com/product/2050). this tester lets us verify both 'sides' work: flip the switch one way to test the display in SPI mode plus SD card, flip the other way to communicate via 8-bit 8080-style and also verify the touchscreen. with all tested, its time for us to hopefully get these displays out the door!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
When you see a round display, do you think... pizza? planet? beachball? no? how about a Stargate animation! there's three parts to getting these funky displays working with raspberry pi over the DSI port: the SPI configuration of the screen, the I2C configuration of the ICN6211 converter and the DTO device tree overlay on the pi itself. all must be perfect for an image to appear! to make it less complex, we're going to only do one part at a time and celebrate the successes. we got the SPI config working with blinking the display on and off, and the ICN config was proven when we displayed a colorbar test pattern. finally we load a DTO up which will tell the pi to look for a 720x720 display off the dsi0 port (https://github.com/timonsku/display-overlays/blob/main/panels/HD40015C40/HD40015C40.dts) and voila! a 60Hz display with full color... we can even play any video off the desktop with VLC and it looks great.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

there's three parts to getting these funky displays working with raspberry pi over the DSI port: the SPI configuration of the screen, the I2C configuration of the ICN6211 converter and the DTO device tree overlay on the pi itself. all must be perfect for an image to appear! to make it less complex, we're going to only do one part at a time and celebrate the successes. first is the SPI configuration: without worrying about the ICN or DTO part, we will send the commands to the display from an on-board attiny chip and then toggle all the pixels on and off using commands 0x22 and 0x23. makes it look like a gigantic LED. but now that we see it working, we can move onto the next stage...ICN6211 config!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
we love a colorbar, oh oh oh oh!red, orange, yellow, green, blue... we love a rainbow when it appears on our TFT display! there's three parts to getting these funky displays working with raspberry pi over the DSI port: the SPI configuration of the screen, the I2C configuration of the ICN6211 converter and the DTO device tree overlay on the pi itself. all must be perfect for an image to appear! to make it less complex, we're going to only do one part at a time and celebrate the successes. we already got the SPI config working - blinking all the pixels on and off - now we look at the ICN configuration (https://github.com/timonsku/Adafruit_CircuitPython_ICN6211) - to make sure the PLL and resolution and sync's are correct (https://github.com/timonsku/display-overlays/blob/main/panels/HD40015C40/HD40015C40.py)! in order to separate it from the raspi MIPI DSI interface config, we turn on BIST test mode and have it display a colorbar (https://github.com/timonsku/display-overlays/blob/main/panels/HD40015C40/HD40015C40.py#L28). if the colors are in the right order we know that we have 2 out of 3 working, and we can move onto the next stage...Device Tree Overlay config!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

yesterday we had the square 4" 720x720 TFT display (https://www.adafruit.com/product/5794) working with our Raspberry Pi DTO + ICN6211 configuration. now we want to move onto a round screen. one thing that was kinda nice about that screen is it does not require an SPI init code - it pops up immediately into RGB TTL mode. all our other screens require configuration. which means now we have a lot of variables: the DTO and kernel driver that writes DSI data, the ICN6211 configuration that sets the TTL resolution and sync, and the SPI config. that's a lot of variables! we're going to back up and just make sure the SPI init is good - to do that we use the ST7701 datasheet to find the 'all pixels on' command. by sending this at the end of the init string and seeing all white display we know that at least that part of the configuration is working, then we can work back and get the ICN6211 test colorbars and finally work all the way back to the DTO setting. display work is really hard but this is something we've done many many times so we are used to juggling so many configs. what really helps a ton is having a known good setup using the ESP32-S3 Qualia (https://www.adafruit.com/product/5800), so we are really glad we got that working firstVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
we took october off from working on this project, but we're back baby! a PR was submitted to allow DTO-level configuration of display timings , rather than having a specialized driver for each display config (https://github.com/raspberrypi/linux/pull/5640) which, if merged in by the raspi folks, will mean we don't need to do specialized kernel compilation or module work. at the same time im working on setting up the onboard attiny chip which will be used to configure the ICN6211 over I2C, the TFT over SPI, and manage the backlight. in order to make it possible to 'hot swap' displays without bustin' out a UPDI adapter, we'll store the configuration code in an EEPROM that is exposed over the Pi's DSI I2C port. or at least, that's the idea! we'll see if it works soon :)Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is so hot, yet so cool: it's the BeagleV-Fire from BeagleBoard.org (https://www.digikey.com/en/product-highlight/b/beagleboard/beaglev-fire) featuring the Microchip PolarFire MPFS025T-FCVG484E (https://www.digikey.com/short/ddw7fmww), a powerful Processor+FPGA combo SoC that has 4x 64-bit RV64GC Application cores, as well as a 23K logic element FPGA. The BeagleV-Fire outfits this chip with a tidy number of wired up peripherals so that you can quickly get started with complex computational requirements without having to spin up a custom PCB.Historically, the BeagleBoard folks have used ARM-core chips: their famous BeagleBone Black (https://www.beagleboard.org/boards/beaglebone-black) contained a TI-built ARM Cortex A8. But recently they've been experimenting more with RISC-V. RISC-V is an 'Open ISA' - which means that you get a well defined, high speed core, that adheres the the RISC-V ISA Specifications (https://riscv.org/technical/specifications/) and use implementations thereof, without having to pay ARM a licensing fee. And recently ARM has looked to raise those fees (https://www.xda-developers.com/arm-increasing-royalty-fees/) - which has a lot more chip makers looking seriously at RISC-V as an alternative core. Now, to be honest, RISC-V is not as mature as ARM, and you're not going to have as much language and peripheral support for it. But...it's hard to argue with free! (https://en.wikipedia.org/wiki/Disruptive_innovation)We've seen RISC-V show up in two spots: mostly in smaller, low-power microcontroller cores like the ESP-C6 (https://www.espressif.com/en/products/socs/esp32-c6), but more recently, in larger boards like this one. One nice thing about having the RISC-V cores be powerful enough to run protected software like Linux is that you don't have to worry as much about compiler or learning the peripheral management because you can just run Python or use the Kernel Ioctl interfaces for hardware - the hard work has been done for you! And for this board you get a ready-to-boot Ubuntu installation. Which is awesome because sometimes you get really odd distro's for SBCs that end up eating all your time and energy to get them into a modern state.Now that you have Linux running, you can use the FPGA to make custom hardware interfaces. To do that you'll need to use Libero (https://www.microchip.com/en-us/products/fpgas-and-plds/fpga-and-soc-design-tools/fpga/libero-software-later-versions) as an FPGA IDE, and use the MAC address of the BeagleV for the floating license. But it does look like you can run libero natively on the BeagleV - there's apparently 'gateware' examples that will be published, for the M.2, SYZYGY, MIPI-CSI and Cape/GPIO hardware interface. So those design blocks can be built upon or tweaked to fit your end-needs. Like other BeagleBoards, the files for the hardware are all published so you can look at the exact schematics and layout files (https://git.beagleboard.org/beaglev-fire/beaglev-fire), there's a Linux kernel fork (https://git.beagleboard.org/beagleboard/linux), Forums (https://forum.beagleboard.org/tags/c/beaglev/15/fire), and Discord chat! (https://bbb.io/discord)If you're burning with excitement to get your hands on one of the new BeagleV-Fire SBC's from BeagleBoard.org (https://www.digikey.com/short/fz434q52), you're in luck because they are in stock right now at DigiKey for immediate shipment! Order today and they'll ship immediately so that you can get started designing your very own RISC-V-based super computation device by tomorrow afternoon.

if you got a Pi 5 (https://www.adafruit.com/product/5812) and you want to log in or debug without ssh'ing or using a monitor and keyboard - there's now a super fast and easy way to get into the UART console - thanks to the new JST SH 3-pin 'UART' port nestled between the HDMI connectors. Use your Pico Probe (https://www.adafruit.com/product/5699) and connect the 3-pin cable to the 'U' port - the probe board will appear as a COM/serial port, and you can open it up with any terminal program. we love using it for kernel debugging because the connection stays open between reboots and you'll get all messages directly printed, plus the early boot messages...even ones before the firmware is loaded or the display comes up.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

for more than a year we've been slowly revising just about every product we make to account for changes in transistors, regulators, diodes, boosters...lots of churn! we're finally up to revision #500 and we're happy to finally get to a product that had to have nearly every component changed: the 3.5" TFT FeatherWing (https://www.adafruit.com/product/3651), the touch driver went from STMPE811 to TSC2007 (https://www.digikey.com/short/v2mf43q9), the screen supplier changed, the boost converter went from FAN5331 to TPS61169 (https://www.digikey.com/short/4zf0d1n2), and we've added a QT port. This demo tests all the hardware functionality - we load a BMP from the SD card, display it on the TFT, then 'draw' on the image with the touchscreen. all is good - we're ready to order the final PCBs!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
We saw this call for help over on X, asking for a DigiKey part number for "graphite based thermal pads" (https://twitter.com/ghost_motley/status/1709160119852765465) . These are used to cool down chips on CPUs or GPUs when performing heavy computation. Normally folks use thermal paste but there's also thermal pads that can be used. These are less messy and are more forgiving of gaps or rough spots between the chip and heatsink. One thing to watch for is a lot of 'marketing heavy' modding parts don't publish specs! So while we were not able to find an exact match for 'KryoSheet' - because they purposefully don't say what the thermal resistivity is, we did find some good matches on DigiKey if you want to use graphite thermal pads in your next product.See the chosen part on DigiKey https://www.digikey.com/short/tftz84bd

Our cute 2.1" round 480x480 TFT display (https://www.adafruit.com/product/5792) has a CST826 capacitive touchscreen overlay - different than the other screens that all have Focaltech FT6336U or similar. Thanks to MakerMelissa we now have support in both Arduino (https://github.com/adafruit/Adafruit_CST8XX_Library) and CircuitPython (https://github.com/adafruit/Adafruit_CircuitPython_CST8XX)! We also got a version of our 4" 720x720 display (https://www.adafruit.com/product/5793) with capacitive touch. Unfortunately this one doesn't have the same 'integrated' style where the CTP pads go through the 40-pin connector, bot rather they're on a separate 6-pin 0.5mm pitch tail. Still, it's worth the effort, so we'll make a lil breakout for the touch connector so you can plug it into the QT port.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is PIC GmbH's LP Series Reed Switch Chains (https://www.digikey.com/en/product-highlight/p/pic/lp-series-reed-switch-chains), a range of a new kind of liquid level sensor. Not surprisingly, this sensor uses a chain of reed switches and a magnetic float to detect the liquid level in a bucket or tank - we've never heard of this kind of sensor, so we picked one up to check it out!Using a single reed switch for determining liquid level is not new - it's a common way to have a isolatable sensor for food-safe or caustic fluids. Compared to some other liquid level sensors like eTape (https://www.digikey.com/en/products/detail/adafruit-industries-llc/464/8558263) which needs to be 'squeezed' by the liquid to give a continuous resistive reading, or sonar (https://www.digikey.com/en/products/detail/maxbotix-inc/MB7092-100/7896780) which needs to be able to bounce air off, or ToF sensors (https://www.digikey.com/en/products/detail/adafruit-industries-llc/3967/17039169) which can be affected by surface reflectivity/absorption, a reed relay is fully electrically and mechanically isolated. The whole thing can be covered in inert materials and easily cleaned or sanitized. For more details on selecting fluid level sensors check out this DigiKey article (https://www.digikey.com/en/articles/selecting-a-fluid-level-sensor-what-you-need-to-know)The PIC LP Series Reed Switch Chain is made of a thick PCB that is routed down the middle and has tightly packed reed switches (https://en.wikipedia.org/wiki/Reed_switch) soldered one after the other with 1K resistors between each one. A each reed switch closes, the two contacts will measure a resistance that contains all the 'lower' 1K resistors in series. So, say if the first reed switch is triggered the resistance will be 0 ohms, if the next reed is closed the resistance is 1K ohms, all the way up to (n-1)*1K ohms where n is the number of reed switches installed. In order to have the reed switches activate with the liquid level, you'll also need a donut/toroid-shaped magnet float (https://www.pic-gmbh.com/en/level-sensors) which is stocked over at PIC or a generic one can be used if you need particular material.The PCB comes bare and you'll need to put it in a tube that matches your material handling requirements. Also, if you need a longer chain, you can abut them end-to-end and solder them - some mechanical stabilization may also be required. Even though this is designed for liquid float sensing, it could also be adapted to be used as a sliding-platform locator: just watch out that you don't exceed the switch activation lifetime limit - it's a few million but these will be hard to replace if they get damaged. Another nifty side-effect of using reed switches is that they can withstand higher voltages, and since they are not powered, can be wired directly into circuitry that is not ground-referenced and don't care about noise, EMI, static or other common annoyances of industrial automation.There's also some other cool items from PIC to check out at DigiKey (https://www.digikey.com/en/supplier-centers/pic-gmbh), such as SMT reed switches (https://www.digikey.com/en/products/detail/pic-gmbh/PMC-1001TS1015/9687557) which we didn't know existed, and individual reed floats (https://www.digikey.com/en/product-highlight/p/pic/level-sensors) if you don't need continuous level detection.If you want to have a fully mechanically isolated level or position detector that is simple, inexpensive and doesn't require external power, this could work very nicely! And best of all, PIC GmbH's LP Series Reed Switch Chains (https://www.digikey.com/en/product-highlight/p/pic/lp-series-reed-switch-chains) are in stock and available right now for purchase at DigiKey in a range of sizes. Order today and you'll be floating on air... er... liquid, by tomorrow afternoon when DigiKey packs and ships your order immediately.

This week's Great Search is on clicky dome switches! We saw a thread on X (https://twitter.com/RueNahcMohr/status/1716162430265602509) showing off the Snaptron (https://www.digikey.com/en/supplier-centers/snaptron) starter kit - you can pick up a sample box kit for free from (https://www.snaptron.com/free-samples/sample-box/) if you want to try these too. We first saw these on the Pocket CHIP (https://shop.pocketchip.co/collections/frontpage/products/pocket-c-h-i-p-new) as a low cost way to create a key array. One new type we saw is the BL series (https://www.snaptron.com/products/standard-domes/bl-series/) which allows having an LED behind the dome - you'll need a reverse mount LED so it doesn't get crushed. And the DT series which allows two level of actuation (https://go.snaptron.com/DT-Series-White-Paper_V2.0).See the chosen part on DigiKeyhttps://www.digikey.com/short/fvdtp82j

Autumn Lights Festival in Oakland, CA is a long-running and beloved Oakland tradition. It takes place at the Gardens at Lake Merritt every October. This event is a fundraiser for the garden, which is a peaceful sanctuary from the hustle and bustle of the city, right on the shore of the lake. Around 100 LED light artists bring their creations out to Autumn Lights every year. This year, we caught up with Yvette Schindler, who created a giant Connect 4 game using laser-etched acrylic, NeoPixels and arcade buttons. It's a fully functioning game where players can face off with each other by standing on either side of the board and pressing buttons to drop a "piece" wherever they'd like. This was a really popular installation -- people were lined up to play all night long. The game also functions as an art piece, with gorgeous colorful animations that run while no one is playing. It is one of the most beautiful and intuitively interactive use of pixels and Arduino we've seen.

This week's EYE ON NPI will have you doing cartwheels and somersaults, it's the E-Switch RT3301 Series Reverse Tactile Switch (https://www.digikey.com/en/product-highlight/e/e-switch/rt3301-reverse-tactile-switch), a spin on the common 6x6 tactile switch, with reverse mounting for easy assembly and clean design.E-Switch manufactures thousands of different tactile switches that are stocked at DigiKey (https://www.digikey.com/en/products/filter/tactile-switches/197?s=N4IgjCBcoLQdIDGUBmBDANgZwKYBoQB7KAbXABYIBdAXzqA) of various sizes, actuator heights, and mounting styles. In addition to the classic 6x6mm tactile switch, (https://www.digikey.com/short/z0m4fjpp) there's also the SMT 6mm tactile (https://www.digikey.com/short/m7440d0f) that can be pick-and-placed. These buttons have built-in round actuators but they're intended to be used with moulded buttons that have a nub to do the actual pressing: the actuator is just for height. Which explains how the through-hole reverse mount 6mm tactile switch is expected to work (https://www.digikey.com/en/products/detail/e-switch/RT1105AF260Q/15221150) - you're going to definitely need an actuator button since otherwise your fingers will bump into the solder pads!The most curious of these is the reverse-mount SMT tactile switch, which was recently featured by DigiKey (https://www.digikey.com/en/product-highlight/e/e-switch/rt3301-reverse-tactile-switch) in their new products section...and with great timing because just a few weeks ago we published a cool Lisp-powered badge project with a built-in keyboard on the blog (https://blog.adafruit.com/2023/10/10/the-lisp-badge-le-lisp-basdgelife-technoblogy/). To make the key labels nice and large, the author used similar switches with an angled layout for tight packing. The result is a nice clean look on the front, without needing to purchase separate key caps.We'll note that the RT3301's actuator is not as long, so using it with a half-thickness board will get buttons that are flush with the PCB surface. That means it's best for use with separate key caps or overlay...but we're also pretty sure that E-Switch will come out with another version that has longer actuator - just like they have a variety of actuator lengths on the non-reverse 6mm tactile switches.If you want to try the E-Switch's RT3301 Series Reverse Tactile Switches (https://www.digikey.com/short/f71n7z29), they're available right now and in stock at DigiKey for immediate shipment! Order today and you'll have reels or cut tape in hand tomorrow afternoon, a great solution to your complex UI panel design problems.

This weeks EYE ON NPI is a real throwback for us, it's the Orion Fans' ML2010 Mini-lab (https://www.digikey.com/en/product-highlight/o/orion-fans/ml2010-mini-lab), a portable engineering toolkit built into a suitcase for easy transport. This Mini-lab reminds us of the MIT Nerd-Kit used in digital and and analog design classes that require construction of circuit labs (http://web.mit.edu/6.111/www/project-photos/s98-projects-photos/s98projects.html). These suitcases were durable ...and super heavy! Thankfully we did not have to carry them back and forth to home each day - there were lockers in the lab. Many a digital-lab student wished we could keep the kits after finishing the course but sadly nerd-kits were not for sale - and we shudder to think what fate would befall us if we neglected to return them. Which is why this NPI caught my eye...finally I can have my very own nerd-kit thanks to Orion Fans and Knight Electronic Products.This silver suitcase contains many common analog and digital-logic tools to help prototype projects on a breadboard:BreadboardPower suppliesFunction generator stimulusSweep ramp generator stimulusPulse generator stimulusProtoboardI/O portsSwitchesIndicatorsHeavy-duty carrying caseThe solderless breadboarding area is made of three 630-point solderless breadboards (https://www.digikey.com/en/products/filter/solderless-breadboards/638), so large circuits with many breakout and dev board PCBs can be laid out. There's also a separate perf-board area (https://www.digikey.com/en/products/filter/prototype-boards-perforated/636?s=N4IgTCBcDaIA4FMBOAzABAIwPYEMkBMQBdAXyA) for higher-frequency work that could be affected by the breadboard capacitance, or when you want more mechanical stability. The perf-board snaps out when your project is done.The power supplies are where analog hackers are going to be happy, particularly folks who are designing exotic motor/power systems or audio/synthesizers: it has both +5, -5, +12, and -12V at 1 Amp output split supplies, and isolated-ground +18 and -18V at 1 Amp outputs, all with 0.1% line/load regulation and short circuit protection. For AC supply design - rare to find, so if you need it this will be a blessing - there's 15VAC center tapped that can supply 500mA. The power supplies are fused, and controlled by a large on/off rocker.Another great feature for analog hackers: there's also a full-featured function generator (https://www.digikey.com/en/products/filter/function-generators/630), with sine/square/triangle out - up to 18Vpp and +-10V DC offset with selectable decade ranges from 1Hz to 1MHz, and low distortion under 100KHz. There's inputs for FM, AM and sweep modulation (https://en.wikipedia.org/wiki/Modulation), for low-frequency RF experimentation.There's also a plethora of connectors and switches so you don't have to figure out how to panel mount connectors or work out mechanical stabilization. For toggle switches, there are 2x SPDT momentary toggles, 2 x SPDT toggles, and 8x logic level toggle switches. D-Sub connectors also: DE-9 and DE-25 in plug and socket format. For connecting to other test equipment, 3x BNCs. And for input/output, 8x red LEDs, a 1K pot, a 100K pot, and an 8 ohm 1/4 W speaker.The Orion Fans' Mini-lab toolkit (https://www.digikey.com/short/bdhcv3pw) would make a great resource at a lab, workshop or classroom. It's hefty and durable but that also means it'll last a long time. It's an excellent step up from just cobbling together parts that can come loose, and you can put it away safely between hacking sessions without the risk of someone 'borrowing' a part! And best of all, it's in stock right now at DigiKey for immediate shipment! Order today and you can be prototyping in style on your very own Mini-Lab by tomorrow afternoon.
I had a chance to chat with Mills from the Flaming Lotus Girls (www.flaminglotusgirls.com) at Bay Area Maker Faire 2023 and see their art piece, Serenity, with interactive flaming firefly sculptures built by students in the San Francisco Area.

The new Raspberry 5 has a new UART port, which is great because the first 4 Pi's used the hardware serial as a UART - which made debugging hard when using something like a GPS. However, unlike the GPIO header UART, this connector is SMT, and much smaller than 0.1" pitch. While we can always contact the Pi folks for a part number, let's figure out what connector it is just using a pair of calipers - then find a cable that will plug in that we can use to get that tasty RX/TX data out!See the chosen part on DigiKey https://www.digikey.com/short/bf8r7j8j

This week's EYE ON NPI will take a load off your mind, it's Nexperia's NPS4053 5.5 V Load Switch (https://www.digikey.com/en/product-highlight/n/nexperia/nps4053-5_5-v-load-switch) - it's Nexperia's first load switch and they did a great job with the NPS4053 which can be used for a variety of situations where you want to separate power supplies for protection or power savings.I'll admit, I've never used a load switch chip before - so this EYE ON NPI was a bit of a learning experience. Traditionally we've used 3 major ways to switch current. First is, of course, a simple switch - we use something like this on our QT Py Lipo BFF (https://www.adafruit.com/product/5397) where we want to allow mechanical switching and the amount of current isn't super high. The slide switch is specified for 300mA and we double-up the DPDT to allow for 600mA. This could be expanded upon with a power switch that can handle up to 240VAC and 5A (https://www.adafruit.com/product/3991) - but of course someone has to flip the switch. We could solve that issue by going with a relay or a solid-state-relay (https://blog.adafruit.com/2023/08/03/eye-on-npi-sensata-crydoms-series-1-ac-panel-mount-solid-state-relays-eyeonnpi-digikey-sensata-digikey-adafruit/) but they have some downsides as well: high cost, large space requirements. We need something much smaller!On our dev boards we have historically used two techniques for flipping on/off power to subcircuits. One is the P-FET high-side switch, which you can see on our Metro boards on the DC jack (https://www.digikey.com/short/d3j7z977). This method is classic, and works well but has a few downsides: you need a second transistor to control high voltages with a low voltage signal since the gate is pulled up to the high input voltage. Also, there's that built-in diode that is will conduct current from the output back to the input - you can see in our schematic how we also have to add a forward-diode to protect against that. Altogether, you would need 2 transistors, a diode and a couple resistors to make a FET-based switch.There's also another downside to FET switches, which is that they are not current limited, so if you happen to be switching a significant amount of current, it could cause a transitory spike on your main power supply...which causes a brownout! Something we experienced when we tried using a P-FET to switch on-off an I2C port. It worked great for low-current sensors but would crash the board when used with a 100mA-draw air quality sensor. So we used a fully separate LDO on the Feather ESP32-S2's (https://www.digikey.com/short/4nj457zb) - this works because we have a volt or more drop from the conversion from 5V to 3.3V so if there's a dip in the voltage, it isn't going to affect the main micro's power supply. This works because the LDO is only a few cents (https://www.digikey.com/short/fnr9jtnj), and we happen to have the headroom. It also has true-disconnect (no extra diode needed!) and is compatible with lower voltage logic signals. But, most devices have a DC/DC converter which is going to be a lot larger than a SOT-23-5 LDO - and there might not be as much headroom.That's where the Nexperia NPS4053 5.5 V Load Switch (https://www.digikey.com/short/ttjt5mjw) comes in! It combines all the analog electronics you need to easily switch loads of up to 5.5V at 2A, with all the niceties that you'd normally have to manage by hand. Instead of a second diode, it has true-cutoff. Instead of a separate current-limiting circuit (https://en.wikipedia.org/wiki/Crowbar_(circuit)), you can set the current limiting with a resistor and the load switch will turn from Constant Voltage to Constant Current mode. The chip also handles transients nicely, with soft-start, so that you don't get a shock to the power supply if the sub-circuit turns on all at once! In addition, there's Under Voltage Lockouts and short circuit protection. If something does go wrong, the chip will disconnect the load and drive the FAULT pin low, so you can communicate to the user that something is amiss. For many of the short/temp/over-current errors, the chip will naturally recover.With an adorable 2x2mm HVSON package and a cost of only 20 cents in quantity, the Nexperia NPS4053 5.5 V Load Switch (https://www.digikey.com/short/ttjt5mjw) will fit into the same board slot as a transistor for not much more, and replace a ton of power management circuitry with elegant simplicity! And, best of all - it's in stock right now at DigiKey for immediate shipment, in both commercial/industrial (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NPS4053GHZ/21286453) and Q100Z variants (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NPS4053GH-Q100Z/21286452).

This week's EYE ON NPI surpasses all labels, it's the Brady M210 portable hand labeller - a perfect addition to any electrician, engineer, scientist, or maker who wants to keep things organized!When we first looked at this labeller we were wondering what makes the Brady device better than the Brother brand labeller we bought a few years ago - but after using it for only a few minutes we were blown away by all the excellent features that come built in. We really recommend you check out the User Manual because there's a lot of capabilities that we did not realize were included in the firmware. (https://support.bradyid.com/s/article/M210-User-Manual-and-Quick-Start-Guide) Here's a run down of some of the things it can do that you will not get with other labellers.Internationalization: Support for multiple languages with fonts and accents to match, for this labeller, the languages are all 'Romantic' and of course many Greek symbols are included. There is a separate Russian product if you need Cyrillic.Symbols: Our home labeller has cute symbols like crafting symbols and clouds - this labeller goes straight for safety symbols such as "you will be electrocuted" or "this is poisonous" or "do not look at with remaining eye" (https://observatory.db.erau.edu/generators/signs/) But also electrical symbols, telecom and home electric.Barcodes and 2D Encodings: Barcodes in CODE39 (https://en.wikipedia.org/wiki/Code_39) and CODE128 (https://en.wikipedia.org/wiki/Code_128) format as well as 2D encodings such as Datamatrix or QR code (https://www.gs1.org/standards/barcodes/2d). Perfect for when you want to include a URL or serial number that is longer than the print label allows. Serialization: printing multiple labels with a start and end value, and custom incrementation, it can even handle alphanumeric serials!Date Stamping / Coding: by setting the date and time on-device, you can insert timestamps based on when it prints. You can format the time and date for 12H/24H, with or without seconds, and different MMDDYY ordering. (https://en.wikipedia.org/wiki/Date_format_by_country)Panel and Terminal Blocks: particularly nice for electricians, you can print out labels that are perfectly spaced for breaker panels, or terminal blocks. In general we noticed that this labeller has a strong sense of spacing so that you can have multiple words or numbers and there's likely a mode that will make them center-equidistant...something that is really annoying to try to do with an everyday labeller.Wire Marking: This one is going to be one of our top uses! For complex wire harnesses, being able to label the wires so it isn't just color you're using to identify functions is amazing. There's a few ways to mark wires (https://www.bradyid.com/resources/guides/how-to-select-a-wire-marker). The easiest is Flag mode, where it will print the text twice with a gap in the middle so you can make a little flag that wraps around the wire. You can use any label size or color to make flags. For less intrusive labelling, you wrap the label around the wire. And coolest by far is the 'PermaSleeve' (https://www.digikey.com/en/products/detail/brady-corporation/M21-125-C-342/11585771) where you can print directly onto heatshrink tubing!Once you have a Brady M210 Label printer (https://www.digikey.com/short/mj7t5fwp) or printer kit (https://www.digikey.com/short/tzjqtm9r) you will use it every day to track and manage your tools and inventory. It's way better than sharpie marker'ing, or sticky notes, with a massive range of different label styles, sizes and colors (https://www.digikey.com/short/77qcpzc5) - all in stock right now for immediate shipment from DigiKey! Pick up an assortment to keep in your lab -- and of course first step is to label the labeller itself so nobody tries sneaking off with it -- when you order today it will ship immediately so you can start labelling everything by tomorrow afternoon.

This week on the Great Search, we've had our eyes on the new Pi 5 announcement - they're not shipping yet but we did get some tantalizing new images including a new PCIe connector on board. PCIe is a high speed bus that will make it a lot easier to add hardware to a Pi computer, including storage cards, cell modules, radios, and co-processors (https://en.wikipedia.org/wiki/PCI_Express) that can use 1 lane of data. A PCIe HAT is expected from Raspberry Pi at some point, and there's a few folks trying to make adapters for M.2, which we covered on The Great Search earlier (https://blog.adafruit.com/2020/10/27/the-great-search-m-2-e-key-connectors-thegreatsearch-digikey-digikey-adafruit/) So this time around let's look for PCIe sockets. We'll try to find one that is SMT and vertical, so a wide variety of cards can be inserted.

This week's EYE ON NPI stands alone as a fantastic new solution for high power charging of large battery packs and also power boosting from battery to system: it's ADI/Maxim's MAX77789 Standalone 3.15A Charger (https://www.digikey.com/en/product-highlight/a/analog-devices/max77789-standalone-3-15a-charger), an all-in-one power management IC that lets you ditch DC power plugs and simplifies your BOM, at an excellent price. We'll also be covering the MAX77787 (https://www.digikey.com/short/wzv7095b) which is the fraternal-twin-sister product: using I2C instead of resistor settings for configuration.We've been covering USB Type C PD sinks and supplies for about a year here on EYE ON NPI & The Great Search, they're an excellent way to ditch those DC barrel jack power supplies (https://learn.adafruit.com/usb-pd-hacks/) and allow folks to use a single connector and standard power supply (https://www.youtube.com/watch?v=C90UnNAlCFQ) for various voltages, from 5V-20V at up to 5A. There's plenty of chips that will connect to a PD source and negotiate that voltage for you (https://www.youtube.com/watch?v=yQea9IEmf28) but now we can start to take advantage of USB PD for battery charging as well!This week's dynamic duo does pretty much everything for battery management. As devices get more complex, and battery cost goes down, the packs included in products are getting bigger. If you're trying to charge a 5Ah battery at standard 5V/1A rates, it will take at least 5-8 hours to do so, when folks really want 1-2 hour charge rates.The MAX77789 and MAX77787 have a buck converter that will deliver up to 3A to the battery for 3x faster charging. But, if you try to draw 3A from a USB 5V power cable, that built-in resistance will cause a voltage droop - remember we need at least 4.5V to have the headroom for charging up to 4.2V or 4.35V Lithium batteries. Thus, these chips use USB PD (https://learn.adafruit.com/understanding-usb-type-c-cable-types-pitfalls-and-more) to request higher voltages when available: 9V or 12V means that we can draw less current to get the same amount of power, which means less resistance loss over the cabling. For pre-C chargers, such as Samsung or Apple or Quick Charge (https://learn.adafruit.com/understanding-usb-type-c-cable-types-pitfalls-and-more) the USB D+/D- pins are used. In such cases where you want to have the data pins available for USB data/sync, you'll need something like the MAX20334 (https://www.digikey.com/short/p8b23vf3) data line switch to flip the pins back to your MCU.The MAX77789 uses resistors on the IFAST, ISET and INLIM lines to set the charge rate, timeout, and pack float voltage, the MAX77787 uses I2C. Both have a couple configuration pins, and LEDs for status monitoring. Both have the ability to also be turned into a boost converter - you can't use both charging and boosting at the same time, but since you can use the SYS voltage when connected to USB, you'll have at least 5V either way. The booster is fixed to 5.1V output. On the '89 the boost is enabled by GPIO, the '87 enables it over I2C.Both chips are available in 0.4mm pitch BGA - which means pad-in-via and multi-layer boards in order to pass the inner configuration traces out. Many of the traces are tripled-or-quadrupled to provide the current carrying capability of 3A charge and 6A peak discharge. An eval board is also available (https://www.digikey.com/short/4dc80hwz) which makes quick verification easy. For the I2C configuration version there's also desktop software to try out various settings - the standalone version has jumpers so you can attach any resistor value.Both the ADI/Maxim MAX77789 (https://www.digikey.com/short/j7zhtj4h) and MAX77787 (https://www.digikey.com/short/wzv7095b) Standalone/I2C 3.15A Chargers are in stock right now at DigiKey for immediate shipment. It's great to see forward momentum in chip design releases now that the shortages have abated: only a year ago we were scrambling for diodes and op-amps and now we have a wealth of great new products to choose from! Order one of these powerful Lithium battery management chips today and you'll have it shipped immediately so that you can start integrating it into your new design by tomorrow afternoon.

As we are plowing through the last of our chip-shortage-recovery revisions, next up we're about to do a bunch of Raspberry Pi HAT displays. HATs (https://www.raspberrypi.com/news/introducing-raspberry-pi-hats/) are 9 years old, and are a standardized way of Attaching Hardware on Top of RPi's. Given the RPi shortage is also over, thankfully, it's time to look at more HATs! One feature that HATs have is an onboard EEPROM that helps identify the board via a set of extra I2C pins - this EEPROM can be used to load device tree fragments, contain MAC addresses, calibration details or other non-secured unique data. We've covered 25Q series SPI Flash memory before, and 24-series looks soooo similar but they are not! Let's look at some options for adding generic 32Kbit / 4 KByte I2C EEPROMs including some things to watch out for so you don't make mistakes we have.See the chosen part on DigiKey https://www.digikey.com/short/v4jn79hjVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/

This week's EYE ON NPI is switching it up, with a look at some high-voltage-capable analog switches - Texas Instruments' TMUX821x Flat RON SPST 4-Channel Switches (https://www.digikey.com/en/product-highlight/t/texas-instruments/tmux821x-flat-ron-spst-4-channel-switches). A simple and effective way to switch and control up to 4 x 100V connections with up to 200mA each from any microcontroller or microcomputer.We carry dozens of different switches (https://www.adafruit.com/category/759), and DigiKey stocks easily 50K different switch configurations (https://www.digikey.com/en/products/result?s=N4IgTCBcDaIM4HcCWAXAxgCxAXQL5A0) from push-buttons (https://www.digikey.com/en/products/filter/pushbutton-switches/199) to toggles (https://www.digikey.com/en/products/filter/toggle-switches/201) but all of these require a person to push the button mechanically, whereas the TMUX series will connect and disconnect based on a separate digital signal, as low as 1.8V and as high as 48V. These are often used for switch audio or video, but are also often used in sensor measurement or test equipment. They're not good for power supply switching, and for digital signals there's often other ways of moving signals around, although they are sometimes used for the data lines of bidirectional digital signaling systems like USB.Like mechanical switches, the TI TMUX family of analog switches are 'bidirectional' (https://www.youtube.com/watch?v=z9GRiYPq7LM) - that means you can pass signal from A to B or from B to A. However, unlike mechanical switches there is no, well, mechanical connection. Instead, the switches are created by putting an N-FET and P-FET back-to-back. This means that there is no switch-bounce (https://en.wikipedia.org/wiki/Switch#Contact_bounce) or contact oxidation (https://en.wikipedia.org/wiki/Electrical_contact).Analog switches are pretty magical, and solve design problems that involve moving an analog signal around without having to hand-build a switch on board, but there are a few things to watch out for when 'modeling' how an analog switch varies from a mechanical one!First up, analog switches have fairly low 'Ron' resistance when the analog switch connection is made - on the order of a few ohms - and that is much higher than a mechanical switch. There is also 'very very high resistance, but not an open-circuit' when the analog switch connection is broken - on the order of a few hundred mega-ohms. (https://www.youtube.com/watch?v=n9EklrCrgH8)And don't forget you will need to have positive and negative power supplies beyond the voltages switched. So, if you are trying to switch 24Vpp signal, that ranges from -12V to +12V, you will need to supply them on the VDD and VSS lines. Also these are not electrically isolated, so add a separate opto/digital isolation (https://www.ti.com/isolation/digital-isolators/overview.html) circuitry if you want to keep your microcontroller fully disconnected from any high voltages.But compared to classic jellybean analog switches like the CD4066 ,(https://www.digikey.com/short/jw44n87t) the TI TMUX series of analog switches have improved circuit protections that will keep you from popping your chips (https://www.youtube.com/watch?v=RTPHjhjUl0E) by accident - especially since this series can be used with up to 100V. Check the datasheet for all details, but highlights include: built in pull-down resistors, protection against over/undervoltage as well as out-of-order voltage application, and latch-up immunity.If you're looking to switch up some analog signals on your next design, check out the Texas Instruments' TMUX821x 4-Channel Analog Switch (https://www.digikey.com/short/r3rhn270) family with 3 different configurations of NO/NC. And all are in stock for immediate shipment from DigiKey! Order tonight and by tomorrow morning you will be switchin' and swatchin' with these low Ron SPST analog switches.

Full tutorial: https://learn.adafruit.com/scannable-links-with-nfc/overviewAre you a connector? Are you always handing out business cards, sending people to your Etsy store, your blog, or your product? Do you meet people at festivals or conventions and need an easy way to connect, and stay connected? This tutorial is for you.With an NFC tag and a few clicks in a smartphone app, you can create a necklace, necktie, hat or costume piece that not only makes you look sharp, but also helps you connect with your people. Simply tap your necklace to a smart phone with NFC technology (which is most of them, these days) and your contact info will appear on their screen like magic.Or, set up a Venmo link on your NFC tag to make a tap-to-pay sign that's even easier for your customers to use than a QR code. NFC tags offer so many possibilities.Visit the Adafruit shop online - http://www.adafruit.comErin St Blaine - http://www.erinstblaine.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

A few weeks ago, we covered the 2x5 0.05" pitch SWD sockets https://blog.adafruit.com/2023/08/14/the-great-search-2x5-0-05-jtag-swd-connector-and-cable-thegreatsearch-digikey-adafruit-digikey-adafruit/ that we have on many of our dev boards. Those connectors are standard issues for programming Arm Cortex chips with SWD or other devices with JTAG. However, sometimes you don't need or want the bulk of a chonky IDC connector - and only some customers will need to field reprogram or debug. But just having pogo pads is more accessible to connect to if you have the specific jig. We'll cover two solutions for 'press fit' programming: Tag Connect standard https://www.tag-connect.com/ and another exciting option we spotted on Twitter, now called X, from arturo182 and abhinav_937 https://twitter.com/arturo182/status/1701760589419208995 , is using a SKEDD REDFIT cable. https://www.digikey.com/short/t1hhf3qjSee the chosen part on DigiKey https://www.digikey.com/short/327pnnbwVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #deskofladyada #thegreatsearch #digikey #hardwarehacking #prototyping #usbhost #tinyusb #featherwing #chatgpt4 #debouncing #swdsockets #tagconnect #skeddredfit

Our last few experiments with playing video+audio on the ESP32-S3 involved converting an MP4 to MJpeg + MP3, where MJpeg is just a bunch of jpegs glued together in a file, and MP3 is what you expect. This works, but we maxed out at 10 or 12 fps on a 480x480 display. You must manage two files, and the FPS must be hardcoded. With this demo https://github.com/moononournation/aviPlayer we are using avi files with Cinepak https://en.wikipedia.org/wiki/Cinepak and MP3 encoding - a big throwback to when we played quicktime clips on our Centris 650. The decoding speed is much better, and 30 FPS is easily handled, so the tearing is not as visible. The decoder keeps up with the SD card file, so you can use long files. This makes the board a good option for props and projects where you want to play ~480p video clips with near-instant startup and want to avoid the complexity of running Linux on a Raspberry Pi + monitor + audio amp. The only downside right now is the ffmpeg cinepak encoder is reaaaaallly slooooow.

This Mini TV demo https://github.com/moononournation/MiniTV by moononournation is perfectly themed for Star Trek day, playing the TOS and STNG intros at 480x480 12fps MJpeg and 22KHz I2S MP3 audio. We'll try Cinepak next, but this was an easy first start, and it looks and sounds great. There's a little tearing effect due to the low frame rate and the display being single, not double-buffered, but considering this is a $4 microcontroller module running Arduino, it's very impressive! This may be the first time we've seen reasonable size-and-quality video+audio playback! This was our last 'test' for the ESP32-S3 TFT Experimenter board. All functionality has been tested, and it's ready to go out for manufacture - only one blue-wire fix is needed to change the default I2C address of the GPIO expander :)Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------@EspressifSystems @StarTrekOfficial @Arduino #StarTrekDay #espressif #esp32 #adafruit #espfriends #ESP32S3 #arduino #startrekfan #minitv #techdemo #audiovisual #innovation #diyprojects #microcontroller #videoplayback #trekkie #engineeringmagic

This week's EYE ON NPI is a treasure, and will measure pressure with pleasure...it's the Amphenol All Sensors' ELVH Series Digital and Analog Pressure Sensors (https://www.digikey.com/en/product-highlight/a/all-sensors/elvh-series-digital-and-analog-pressure-sensors). A family of temperature and pressure sensors with a ton of different configurations so you can definitely fit it into your design no matter what interface or usage range. These sensors integrate a process improvement to the sensing element: the CoBeam2 series is a MEMS etched piezo-resistive 'strain gauge diaphragm'. This li'l chunk of silicon creates a Wheatstone bridge where the pressure against the die makes microscopically small changes to the resistances that can be measured on the differential output.That's not surprising: pretty much all absolute or differential pressure sensors come as 4-element Wheatstone bridge configuration (https://www.digikey.com/short/jp83d457) - and these require extra analog circuitry to handle and amplify the small voltage change readings, or a high precision ADC - we've covered 24-bit ADCs for reading bridge sensors on earlier EYE ON NPIs (https://www.youtube.com/watch?v=7Xkr7OjHQfU). With the ELVH family of sensors, you can get cleaned-up ratiometric analog output, or ready-to-integrate I2C or SPI - so you can pair these even with fully-digital microcontrollers or microcomputers that have no analog inputs. Plus, since its digitized already, you also get bonus status bits and temperature reads.This full family of pressure and temperature sensors comes in a dizzying set of possible packages and configurations, from SMT J-Lead to through hole DIP or SIP. There's also both absolute and differential input-ports, and barbed, needle or flat ports that can connect with common tubing to measure pressure inside a cavity or ambiently. Of course, temperature will always be an 'on-chip' ambient measurement. For any sort of industrial or medical purpose, you can pick the pressure range from as low as 1inH2O (0.0025 bar) to +10 bar. Finally, both I2C and SPI are available for digital read-out, or analog if you want to maintain compatibility with older sensors.If you're designing a product that requires measuring air or gas pressure, and you want to skip the whole analog-front-end development part to get to market fast - check out these Amphenol All Sensors' ELVH Series (https://www.digikey.com/en/product-highlight/a/all-sensors/elvh-series-digital-and-analog-pressure-sensors) - DigiKey stocks almost 200 different varieties of the ELVH sensor family (https://www.digikey.com/short/m4vr4wr5) which means that even if your requirements change during R&D, you will be able to get perfect pressure readings. Since they are in stock for immediate shipment, you can order tonight and get any flavor you like by tomorrow morning.

This light and proximity sensor using the VCNL4020 https://www.digikey.com/en/products/detail/vishay-semiconductor-opto-division/VCNL4020-GS08/2813348 was designed a few months ago, but we were dragging our feet on writing the library code as its kind of a tedious process. Now, with our new BFF ChatGPT4, we can crank through a library with minimal typing. Of course, we check each function and #define as it is written - sometimes typos and misunderstandings come through. But overall, it's a much faster and easier process. We wrote a full-coverage library and example sketches in only a couple hours. Here's the chat log https://chat.openai.com/c/854d8c05-2bb6-46df-acdb-d2ea649ddfe2 - The output still needs to be cleaned up a tad, but you can see the library here while we hack on getting it to pass CI https://github.com/adafruit/Adafruit_VCNL4020Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#openai #chatgpt #arduino #adafruit #opensource #opensourcehardware #ai #VCNL4020 #proximity #sensor #coding #hardwaretesting #librarydevelopment #prototyping #automation #developerlife #electronics #embeddedsystems #breakoutboard #innovation

One of the big tasks that Ladyada still has to spend a lot of time on is writing Arduino libraries for all our devices and sensors, particularly all the I2C & SPI chips out there! These ICs use register maps and sub-byte addressing to set dozens of configurable knobs and switches, and a good driver lets folks set and get all of the noodly bits. However, there is yet to be a standard format to get that configuration map. Instead, you have to pore over datasheets with long lists of binary tables and bit insets to figure out how to convert that into C or Python code. It is tough. Only a few folks can write an excellent comprehensive library.... but Ladyada can & has! In fact, there are hundreds of Arduino libraries on Adafruit's GitHub https://github.com/orgs/adafruit/repositories, all in the Ladyada 'style,' using Adafruit_BusIO for I2C / SPI register addressing https://github.com/adafruit/Adafruit_BusIO/ and since ChatGPT 4 was trained on all of it, we can ask it to become a mini-Ladyada to write new drivers. With a PDF parsing plugin, we can even upload the chip's datasheet to extract register names, values, create enum tables, and text for doxygen comments. Here's the chatGPT log for the video https://chat.openai.com/c/f740eb57-17a6-41e3-ae0a-12da959a1f4c - and here's a previous one that is more 'complete' https://chat.openai.com/share/f44dc335-7555-4758-b2f9-487f9409d556. The amount of time it takes for ChatGPT to write a driver is about the same as it would take Ladyada, and you definitely need to be eagle-eyed to redirect the AI if it starts making mistakes... but it can be done even when Ladyada is tired after a full day of baby-care, or at the same time as pumping https://www.youtube.com/watch?v=EpbH-sXRNps - plus there's a lot less continuous typing/mousing so her wrists don't ache the next day!Do you use ChatGPT for electrical engineering or coding work? Any suggestions on how to make this even better? This is only our 3rd day using this tool, so we're getting started with how to integrate it into our workflow.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------@OpenAI @Arduino #chatgpt #openai #arduino #adafruit #pdf #libraries #drivers #datasheet #codingtools #chipdriver #techinnovation #chatgpt4 #electronics #opensource #hardwarehacks #engineerlife #automatedcoding #codinglife
Now that we have somewhat-kinda-sorta working support for RGB TFT displays on the ESP32-S3 - shout out to Jepler, who is doing the hard work over in this PR https://github.com/adafruit/circuitpython/pull/8351 - its time to test it with wifi too! That's right, the S3 can do wifi and these big displays at once, and CircuitPython is a beautiful framework for it since its so fast to iterate. This code snippet is based on PaintYourDragon's moon clock code here https://learn.adafruit.com/moon-phase-clock-for-adafruit-matrixportal but pared down for testing.

This week's EYE ON NPI will "Speak Friend and Enter" your wireless connectivity toolbox, it's TE's LEMBAS LTE/GNSS USB Modem (https://www.digikey.com/en/product-highlight/t/te-connectivity-amp/lembas-lte-gnss-usb-modem) an easy-to-use full powered cellular and GPS modem designed specifically to be used with single-board Linux computers (SBCs) to add networking and location tracking with a simple plug-and-play USB connection.We bought one and popped it open - not recommended because it will void your warranty - and found inside is a Quectel EC25-AFXD module (https://www.digikey.com/en/products/detail/quectel/EC25AFXGA-128-SGAS/13278280) - an LTE Cat 4 data-only module with high speed uplink and downlink when LTE is available, and GSM/GPRS backward-compatibility for remote areas.Quectel EC25 is a series of LTE Cat 4 modules optimized specially for M2M and IoT applications. Adopting the 3GPP Rel-11 LTE technology, it delivers maximum data rates up to 150 Mbps downlink and 50 Mbps uplink. Designed in the compact and in a unified form factor, the EC25 series is compatible with Quectel multi-mode LTE Standard EC21 series/EC20-CE/EG25-G/EG21-G modules and UMTS/HSPA+ UC200A-GL module, which allows for flexible migration among them in design and manufacturing... backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can be connected even in remote areas devoid of 4G or 3G coverage.EC25 series supports Qualcomm® IZat™ location technology Gen8C Lite (GPS, GLONASS, BDS, Galileo and QZSS). The integrated GNSS greatly simplifies product design, and provides quicker, more accurate and more dependable positioning.The LEMBAS has a lot of little details that shows the design team focused on a high quality build and removing any obstacles to use. For example, instead of a 'USB stick' style modem that blocks all of the USB ports on your raspi, the modem uses any USB Type C cable - this also allows the user to place the LEMBAS wherever the antenna will get best reception. When we opened it up, we noticed that the board was conformal coated (https://www.digikey.com/en/products/filter/coating-grease-repair/642), so it will handle being exposed to humid air, although please note it's not rated for outdoor use. The SIM card is pre-installed but can be removed / replaced easily if a particular data service is desired. We also thought the status LEDs that appear as part of the TE logo showed a cute designer touch.One handy design decision that makes the LEMBAS easy to get started with: inside is a 2-port USB hub (https://www.digikey.com/en/products/detail/texas-instruments/TUSB4020BIPHP/5724124) so that, when plugged into USB, it shows up as both the modem interface and a small USB storage key. On that storage are all the files you need to run to install the modem interface on an Arm32 or Arm64 computer like the Raspberry Pi. This definitely solves the "to get on the internet I have to install my wireless drivers but I can't get onto the internet because I haven't installed my wireless drivers" problem.And of course, there's a GNSS inside as well, which makes this perfect for asset tracking or geo-locating projects where you need to know where the code is running from. It's ready to go in an instant and with native Linux support for cellular modems, you don't need to do any AT command noodling - use Python or node.js or whatever language your application is and open secure sockets like normal.If you've got a hankerin' for a piece of Elvish-quality technology that will let you communicate anywhere in the world, even on the top of Mt. Doom, you can pick up a TE LEMBAS LTE/GNSS USB Modem (https://www.digikey.com/short/4172bndv) from DigiKey today and it will ship to you as fast as a gigantic eagle so that you can get started tomorrow morning... right after second breakfast!

IPS TFT displays, and 3.5" floppy drives are like surf-n-turf: at no point did a lobster or cow ever meet each other before being plated at a restaurant, yet they are a tasty combination. We are testing a 4" 720x720 square display with a capacitive touch overlay using our Espressif ESP32-S3 TFT experimenter board. At this resolution, we're definitely pushing the capabilities of our lil Tensilica chip, but it's still an excellent way for us to verify the displays are good before we maybe get them set up on the ICN6211 DSI-to-RGB converter https://youtu.be/jJQQbaxTS28

With our ESP32-S3 TFT experimenter board, we're now able to use the Arduino_GFX https://github.com/moononournation/Arduino_GFX library by moononournation which has native RGB TFT support and excellent example code. This example is playing MJPEG files, a simple animation format https://en.wikipedia.org/wiki/Motion_JPEG with just JPEGs glued together. We wired up a MicroSD card over SPI for quick file storage and retrieval, or 1-bit MMC works, too. files are converted with ffmpeg: 'ffmpeg -i "wash.mp4" -vf "fps=10,vflip,hflip,scale=-1:480:flags=lanczos,crop=480:480" -pix_fmt yuvj420p -q:v 9 wash.mjpeg', natch! And then they play, about 9fps is the rate we're getting for 480x480 pixels.

This week's EYE ON NPI will make your sensors soft and luxurious thanks to the Renesas ZSSC3241 Sensor Signal Conditioning IC (https://www.digikey.com/en/product-highlight/r/renesas/zssc3241-sensor-signal-conditioning-ic) - which, like a fancy bottle of hair conditioner, will de-tangle any frustrations you have with using resistive sensors that require amplification and filtering.
Many "sensors" that engineers use to measure temperature, pressure, force, light, etc, are actually implemented as resistive sensors. For example, take your common CdS cell (https://www.digikey.com/en/products/filter/photo-detectors-cds-cells/540) also known as an LDR - Light Dependant Resistor. The CdS material has an interesting property that as light shines on it, the resistance decreases. Another common sensor is the PT100 or PT1000 temperature sensor (https://www.digikey.com/en/products/filter/temperature-sensors/rtd-resistance-temperature-detector/535) those are known as RTD - Resistance Temperature Detector - and have a tiny sliver of platinum that has a near-linear increase in resistance as temperature increases (https://www.digikey.com/en/products/detail/honeywell-sensing-and-productivity-solutions/HEL-705-U-0-24-00/3073062). A third example is the classic strain gauge, made of a thin plate of patterned metallic material that very slightly changes resistance as it is deformed (https://en.wikipedia.org/wiki/Strain_gauge).
That kind of rough estimation works great for beginners or simple light sensing, but will not cut it when you have to use a strain gauge at the supermarket to measure pounds of veggies: you want it to be very precise, at least within 1% or better! And if you're using a temperature measurement for a scientific process, you may need to get within 1 degree C or better. You can usually improve the quality slightly by having a 1% or 0.1% precision resistor, adding an op-amp gain stage, upgrading your ADC from 8 or 10 bit to 16 or 24 bits - however you will still need to adjust calibration from sensor-to-sensor as well as account for temperature and/or humidity.
That's where the Renesas ZSSC3241 Sensor Signal Conditioning IC (https://www.digikey.com/short/q1w59d7c) comes in! It's designed specifically to make any resistive sensor easy to wire up and interface with SPI, I2C or 1-Wire. You can use Wheatstone half-bridge, full-bridge or divider configuration so it's good for strain gauges or RTDs. There's even analog output!
The ZSSC3241 provides measurement value readouts and programming capabilities via an I2C, SPI, or one-wire interface (OWI). Three different operation modes allow optimal development of digital, digital-analog, and analog-output smart sensor modules including wake-up on request, continuous-on/fast-response, and automatic/cyclic sensor measurement operations. Absolute and ratiometric voltage, current-loop, or interrupt analog outputs are supported by the ZSSC3241. The analog output options and digital interface options (for calibration and/or a digital application interface) can be combined.
Some great stuff that is included in this chip includes dual PGA stages with up to 300x and 1.8x gain, mV offset shift correction, 12 to 24 bit adjustable ADC resolution - lower resolutions will be faster, adjustable sensor bias current, adjustable temperature compensation, oversampling and averaging, error fault reporting, NVM storage for calibration details, interrupt output on value change, and configurable cyclic measurements with sleep mode (https://www.renesas.com/us/en/document/dst/zssc3241-datasheet?r=25417946) - as well as many other configurations that you can check out in the datasheet. While there are many ADCs that one can use to read resistive bridge, we've never seen one with so many knobs for getting the exact right data out without needing a lot of extra massaging....and the pricing is great considering how much more you get than a normal off-the-shelf ADC chip.
If you want to get started fast we recommend getting the ZSSC3241 Eval Board (https://www.digikey.com/en/products/detail/renesas/ZSSC3241KIT/19234863), particularly since it some with desktop GUI software that can be used to test out the zillions of configuration settings directly with your sensor of choice wired up, without having to go through a ton of re-compilation cycles.
Both the Renesas ZSSC3241 Sensor Signal Conditioning IC (https://www.digikey.com/short/q1w59d7c) and Eval Board (https://www.digikey.com/en/products/detail/renesas/ZSSC3241KIT/19234863) are in stock now for immediate shipment from DigiKey. Order today and you'll get those chip in hand by tomorrow afternoon, so that when you are faced with your next resistive sensor project, you'll skip the struggle and go straight to soft, silky, sensor success.

We showed off some fabulous shaped displays last week - and now we're getting them running! This is a 2.1" 480x480 round display with SPI configuration and an 18-bit RGB interface. Thankfully there is already an Arduino library https://github.com/Lzw655/ESP32_Display_Panel that supports the SPI configuration over port expander stuff on this eval board, plus the touchscreen drivers, too - it saved me a lot of time! The chipset is ST7701, a typical TFT panel driver. You definitely have to initialize the display first with the proper configuration before you can blast RGB data for it to show up, but we were able to noodle that together here https://github.com/ladyada/ESP32_Display_Panel/blob/master/src/lcd/ST7701.cpp#L37, and now it's looking great. Now we know this display and touch setup works, we'll start ordering the displays for us to stock and use.

This week's EYE on NPI is going to stick around for a long time: it's 3M's RP+ VHB™ Tapes (https://www.digikey.com/en/product-highlight/3/3m/rp-vhb-tapes) the latest version of the 3M VHB family that has been solving 'how to stick this to that' for over 40 years.
Digi-Key stocks all sorts of shapes from strips, rolls and sheets - and all the different thicknesses, temperature gradients and adhesive variations.
3M VHB tapes (https://www.digikey.com/en/product-highlight/3/3m/rp-vhb-tapes) have been used for almost every industry: from architectural, to automotive, to appliances and electronic device both hand-held and large-scale. VHB stands for Very High Bond, so it's used for semi-permanent installations. Chances are you've used it before, think of the last time you had to stick something together and it came with a red plastic liner - our desk's headset hanger came with a 2"x2" square and it's been holding strong for almost 10 years! VHB doesn't require the mix-and-apply messiness of epoxy (https://www.digikey.com/en/products/detail/3m/DP100-CLEAR/8635645), it's way stronger than hot glue (https://www.digikey.com/en/products/detail/3m/TC-TC-Q-GEN-II/17139392) and it won't dry out like plain foam tapes.(https://www.digikey.com/en/products/detail/3m/4116-1-2-X36YD/5127897).
Usage is simple when hand-applying: prep the surface by cleaning first so there's no dirt or dust or oil, dry and abrade if needed - most surfaces do not need abrasion but it can increase the bond strength, apply one side of the tape and apply pressure to 'wet-out' the adhesive into the surface, then remove the thin plastic sheet cover, and press on the other side to the tape. Apply firm pressure again to make sure the adhesive squeezes out. The bond will be at 50% strength after 20 minutes, 90% after 24 hours, and 100% at 72 hours. You can speed it up by heating to 150 C / 66 F for one hour. (https://multimedia.3m.com/mws/media/1400379O/3m-vhb-tape-design-guide.pdf)
In addition to shapes, there are also different thicknesses and firmness to the foam - up to 1.6mm thicker foam will be able to conform to rougher uneven surfaces but now the foam itself has some flexibility. Some VHBs can handle high or low temperatures for outdoor or industrial uses. For electronics and robotics, it can be great for attaching displays, mounting sensors, or making enclosures screw-less.
DigiKey stocks a wide range of different lengths and widths of 3M VHB tape (https://www.digikey.com/en/product-highlight/3/3m/rp-vhb-tapes) from half-inch (https://www.digikey.com/en/products/detail/3m-tc/RP-040GF-0-5-X18YD/17197505) to 6" wide (https://www.digikey.com/en/products/detail/3m-tc/RP-060GF-6-X18YD/17197489) to massive 44 inch wide (https://www.digikey.com/en/products/detail/3m/RP-060GF-44-X36YD/16684748) rolls! There are also sheets that can be cut by hand or with a die (https://www.digikey.com/en/products/detail/3m/RP-040GF-8-5-X11/16684766) all in stock and available for instant shipment.
So if you need to stick this-to-that and keep it that way for a long time, order some VHB tape from DigiKey today and you can have it in hand by tomorrow afternoon.
This week's EYE ON NPI is going to give you life, we're looking at Nexperia's Battery Life Booster ICs (https://www.digikey.com/en/product-highlight/n/nexperia/battery-life-booster-ics), an interesting solution for dealing with common coin cell batteries as an inexpensive power supply for your small electronic products. The marketing copy for this chip series is pretty eye-catching, with copy that they are "designed to extend the life of a typical lithium coin cell battery by up to an order of magnitude (10x) while also increasing its peak output current capability by up to 25x" (https://www.digikey.com/en/product-highlight/n/nexperia/battery-life-booster-ics) Quite a claim!
So let's take a look at what this chip can really do, and why we need it to help with our coin battery-powered designs. Primary Lithium LiMnO2 coin batteries (https://www.digikey.com/en/products/filter/battery-products/batteries-non-rechargeable-primary/lithium-manganese-dioxide/90) are hard to beat when you want ultra-dense, low-cost power that is very small. They are the smallest form factor of user-serviceable battery. And the power density of coins - plus their flat shape - makes them great for wearable devices, medical sensors or hearing aids, wireless nodes, anything that is smaller than a finger.
With a nominal voltage of 3VDC, and 280 Wh/kg density, they are more dense than a AA alkaline. LiSOCl2 batteries (https://www.digikey.com/en/products/filter/battery-products/batteries-non-rechargeable-primary/lithium-thionyl-chloride/90?s=N4IgjCBcoCxgTFUBjKAzAhgGwM4FMAaEAeygG0QBmANgFZKEQBdIgBwBcoQBldgJwCWAOwDmIAL6SgA) are even more dense, with 3.6V nominal and 500 Wh/kg - twice the density of LiMnO2 or Alkaline. Both are non-rechargeable batteries, and while fairly inexpensive when bought in bulk, they can add up in cost when buying from a grocery store, so making sure that they last a long time is essential for a good customer experience.
The Energizer Lithium Coin Handbook and Application Manual (https://data.energizer.com/pdfs/lithiumcoin_appman.pdf) is chock full of good advice for folks who want to use a CR2032 or similar coin battery to power their products. It's written with engineers in mind, so a lot of the document covers how the nominal voltage and current, 3V and 240mAh, are deeply affected by shelf life, internal resistance, temperature, and pulse effects. The biggest downside you will see on coin batteries is their relatively high internal resistance - IR. Whereas alkaline and LiPoly batteries have internal resistance well below 1 ohm, the IR of a CR2032 is 9 ohms. So say you want to draw 100mA from a CR2032, even if just for a few millisecs - that 0.1 A turns into a .9V drop across the IR which means what you thought was a 3V power supply is now 2V - too low for your microcontroller or radio to run. Since the power lost across the IR is 2IR and R is fixed, it's doubly important that you keep that I low, so that you can minimize IR loss and use as much of that 700mWh stored energy. In our 100mA example, 30% of the battery energy is lost to resistor heat dissipation!
That's where Nexperia's Battery Life Booster ICs (https://www.digikey.com/en/product-highlight/n/nexperia/battery-life-booster-ics) come in. They are designed to be used with products that don't need continuous battery drain, that is they have a very low duty cycle where the user presses a button a few times a day or maybe the sensor node transmits only once a minute. During that short transmit or usage cycle, a radio or LCD display may need up to 200mA but its for a very small amount of time and the voltage needs to be stable. The NBM family of chips do this by slowly sipping a small amount of current from the battery, keeping that I low so that the 2IR power loss is minimized, then use that constant current to boost a voltage onto a large storage capacitor. The capacitor is chosen to have high capacitance and high voltage for a large total Joule storage capacity.
All four variants of the Nexperia NBM family, NBM7100A (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM7100ABQX/19109915), NBM5100A (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM5100ABQX/19109703), NBM7100B (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM7100BBQX/19110140) and NBM5100B (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM5100BBQX/19109874) are in stock right now at DigiKey for immediate shipment! Order today to pick up these chips that will pay for themselves in one battery life-cycle by adding a PMIC to your coin-battery powered products, and DigiKey will ship your chips immediately so you can start integrating them by tomorrow afternoon.

A "DIP chip clip" sounds like those plastic thingies you put on a bag of Frito Lays' to keep them crispy, but really we're talking about clips that let you snap onto a DIP or SOIC package component to probe or program.
They're particularly handy for in-situ analysis or communication, often used for dumping memory chips or logic analyzer uses. We had someone ask us about this particular clip: https://twitter.com/RndMnkIII/status/1616706574252183557 from social media - it says it's from 3M but what's the part number, and are there other sizes available? Let's go to DigiKey and find out!

Whew, it has been a JOURNEY to revise this 2.8" TFT shield https://www.adafruit.com/product/1651, but we finally see the light at the end of the tunnel. By setting up the TSC2007 through a secondary LDO connected to the power-reset chip, we've eliminated the annoying I2C latch-up. So now we have to design a tester. In this case, we will use a Metro RP2040 https://www.adafruit.com/product/5786, quickly becoming my go-to Metro for test jigs since it has many GPIO, a built-in ROM bootloader, and fast peripherals. Here the chip looks for an SD card plugged into a shield, then displays the image with a touch paint interface for testing all functionality fast! We will order these PCBs tonight and finally put this revision behind us.

Coming soon - this is a quick sketch we did of an RGB TTL driver PCB to help us try out all our funky-shaped displays. We reused most of the Matrix Portal S3 PCB, but instead of the RGB matrix connector, we popped on a 40-pin FPC. 16 GPIO go to the RGB pins, then there are 4 control pins for HSYNC, VSYNC, DE, and PIXCLK. Three more pins for touch screen I2C and IRQ. Then a NeoPixel, two buttons, and 3 SPI pins for configuring the screen controller, and we're almost out of pins! An I2C GPIO expander could save us a couple pins at the expense of more complex drivers, but for now, we will make it easy to get the displays running, and we can play silly pin games later.

For our ICN6211 breakout dev board, we will support classic 40-pin 800x480 displays but what about some funky shapes? A second standard 40-pin connector pinout is used on square, bar, and round displays. Some of these have capacitive touch overlays, and all are RGB666 with different resolutions. The 2.1" and 4" round ones look fantastic, as do the bar displays. We even got a 'half round' display that looks like it would be used for car gauges. There are quite a few steps next, but we're getting there - also, the fun fact is that the Espressif ESP32-S3 has RGB TFT support and can drive these displays! Hmmm...

On our latest ESP32-S3 board, we added a JTAG connector, as we do on many Adafruit Metro microcontroller boards. This is a 'standard' port for SWD or JTAG that is smaller than the common 2x10 connector.
This size is common to many debuggers like the Atmel ICE (https://blog.adafruit.com/2022/07/01/the-great-search-programmer-debugger-for-atsamd21-chips-adafruit-digikey-microchipmakes/) or J-Link (https://www.digikey.com/en/products/detail/segger-microcontroller-systems/8-08-00/2175882). The connector is a "jellybean" part, with many possible vendors. Let's find a few options that you can put onto your next dev board for easy debugging!

It's not often... but every few months, one of our sensor drivers stops working due to hardware changes. It happened this week with the AHT20 tester - for some reason, it doesn't init anymore! What would typically turn into a multi-hour debugging session is a lot easier since we started using an intermediary library called BusIO for I2C/SPI device interactions https://github.com/adafruit/Adafruit_BusIO - there is a single #define we enable to turn on print debugging and when we recompile and upload - voila we see full translation details including stops and transfer failures. Turns out the secret calibration command no longer exists on AHTs; a quick PR https://github.com/adafruit/Adafruit_AHTX0/pull/13 , and we're back in business!

This week we're doing some revision work on our 2.8" resistive TFT screen shield (https://www.adafruit.com/product/1651) to modernize it and also replace some unavailable components. Once neat thing about this shield is that since the display is almost exactly the same size as an Arduino, it uses all SMT headers to plug into the mainboard.
SMT headers are useful to avoid a selective or wave-soldering step, or in this case, to avoid contact with a metal plate backing. DigiKey, of course, stocks many sizes of these headers and they're not too expensive! Let's take a look at how to find SMT 'male' pin headers on DigiKey in a variety of sizes - we'll also cover some common mistakes when specifying this kind of part!

We sometimes have 'Coming soon' products in the shop - this is usually when products are done and hand-verified, but the automated tester still needs to be finished. For example, this Metro RP2040 https://www.adafruit.com/product/5786, which we have the tester here. Typically metros are tested on a Raspberry Pi, but in this case, we're using the Pico Brains board https://github.com/adafruit/RP2040-Based-Tester-Brains-PCB to do it, and it's able to do all programming and test in 10 seconds - which means we can offer the Metro RP2040 at a very nice price! We'll hand this over to our test-and-prep team and schedule the work order next; you can sign up to be notified when we get the Metro RP2040 in stock next week https://www.adafruit.com/product/5786

Expand your project possibilities, with the Adafruit PCF8575 GPIO Expander Breakout - an affordable 16 channel I2C expander. GPIO expanders work like this: you have a board with some number of GPIO but not enough for your project - maybe you need more buttons or LEDs. Connect it over I2C and then you can send/receive I2C commands to control the GPIO pins to write and read them. It's going to be slower than direct GPIO access, but maybe that doesn't matter if it takes a millisecond instead of a microsecond. You only need the two I2C pins, and you can even share the I2C port with other sensors and devices. Heck, you can even add more expanders for massive I/O control!

This week's EYE ON NPI is gonna do you a solid, thanks to Sensata - Crydom's Series 1 AC Panel Mount Solid State Relays (https://www.digikey.com/en/product-highlight/s/sensata-crydom/series-1-ac-panel-mount-solid-state-relays).
Solid state relays are a great replacement for mechanical relays, when you want to have high speed switching or want to avoid contact corrosion and replacement. Crydom makes a ton of different SSR's in a variety of power ratings, and while they share the same name as mechanical relays...there's a lot to watch out for when updating your designs!
We've highlighted SSR's before on EYE ON NPI (https://blog.adafruit.com/2021/01/07/eye-on-npi-te-ssrmp-series-solid-state-relays-eyeonnpi-digikey-teconnectivity-digikey/). As we've covered before, usually when folks start out turning AC power on and off, they tend to use a relay. Relays (https://en.wikipedia.org/wiki/Relay) are simple: inside is a mechanical switch with a ferromagnetic throw. When a nearby coil of wire has current going through it, the coil becomes an electromagnet and pulls the throw to one side. Relays are electrically and mechanically isolated because there’s air between the electromagnetic coil and the switch throw. They're very inexpensive and come in many shapes and power capabilities. (https://www.digikey.com/en/products/filter/power-relays-over-2-amps/188)
Because relays are electro-mechanical, they have to two properties that may be undesirable. First is speed: it takes a few milliseconds (say about 10ms) to energize that coil and move it to the side. The second is mechanical wear and failure: relays will eventually fail from mechanical stress or oxidation (https://en.wikipedia.org/wiki/Contact_protection). Every time you switch the relay, a little arc is formed from the mechanical chatter, which creates a little burn on the contact. It’s a very small oxidation, but it adds up, and the more you use a mechanical relay, the faster it will fail. The fail rate depends on the load type, activation voltage, contact material, etc., but they’re in the 10s of thousands. Relays not meant for high speed or repetitive switching, which is why a lot of them are plug-in or easily swappable.
That’s where SSRs come in! DigiKey carries over 3,000 different SSR configurations from Sensata (https://www.digikey.com/short/j2mpw3br) including a few options that can control DC and can be switched at low voltages like 3 or 5V DC, great for integration with a microcontroller or microcomputer. Some of the SSRs like the D2490 (https://www.digikey.com/en/products/detail/sensata-crydom/D2490/140621), can even handle up to 90 Amps at 280VAC! These SSRs come in a classic 'hockey puck' shape - two large slots makes them easy to mount onto a heat sink, then 4 terminal blocks with plastic protection. And one of the nice things about Sensata SSRs is that there's a whole family of accessories such as clear plastic covers, thermal pads and heat-sinks.
The heat-sinks, in particular, are going to be really important when dealing with switching high currents. For example, the D2490 (https://www.digikey.com/en/products/detail/sensata-crydom/D2490/140621) has a forward voltage of 1.15V on the output, which means that at 10 Amp output, you'll see 1.15 * 10 Amp = 11.5 Watts of power to dissipate - not too bad - but that power rises linearly, so at 20A its 23W, and at 40A its 50W. That heat needs to be pulled away, and a big chunky heatsink will do the job nicely. We've noticed that SSRs tend not to be cooled off with fans, probably because it would be a source of failure in a dusty environment. Check out the Senata documentation for how to calculate your heat sink size (https://www.sensata.com/sites/default/files/media/documents/ourproducts_HS-Series-Heat-Sinks_brochures.pdf), DigiKey also stocks all of the Sensata SSR Heat Sinks you can carry (https://www.digikey.com/en/product-highlight/s/sensata-crydom/series-1-ac-panel-mount-solid-state-relays) as well as thermal pads, lug terminals and clear covers that protect you from high voltage, and the SSR from your grubby fingers.
No matter what load you're switching, Sensata has an SSR that will fit perfectly into your design & budget with over 3,000 different SSR offerings (https://www.digikey.com/short/j2mpw3br) - all stocked by DigiKey for immediate shipment! Order your Sensata Crydom SSR and matching heat sink today, and you'll have a safe and reliable solid state relay in your hand by tomorrow afternoon.

We juuuuust plugged in this uBlox RTK F9P shield into USB and given the intense cost of these modules https://www.digikey.com/en/products/detail/u-blox/ZED-F9P-04B/15761778 we definitely had a nervous twitch but then we heard the "ba-dunk" of enumeration and wheeeewww it came up as a serial port. Heartened, we soldered on a right-angle SMA connector https://www.adafruit.com/product/1865 and connected a chonky active antenna https://www.digikey.com/en/products/detail/u-blox/ANN-MS-0/9817931 . Start up a copy of u-center and huzzah, there is GNSS data streaming out. Next up, we have to figure out what we want to use as the underlying transport layer from base station to rover - maybe an ESP32-S3 Metro https://www.adafruit.com/product/5500 and ESP-Now? more research is needed!

As we were working on our DSI board, we noticed that, on one of our Pi's, the CSI connector clip had snapped off - sometimes when you're noodling around you can break the retaining clips, they're really not meant for repeated insertions. If this happens to you, or if you want to add a CSI/DSI connector to your design, it's better to fix the clip than to wastefully throw away the whole board.
Let's find both vertical and horizontal replacement 15-pin connectors with 1mm pitch!

This week's EYE ON NPI is a new spin on an old familiar classic, it's Arduino's UNO R4 Minima and R4 WiFi Boards (https://www.digikey.com/en/product-highlight/a/arduino/uno-r4-minima-and-r4-wifi-boards) now in stock at DigiKey for folks who want a 5V microcontroller board with classic UNO-compatibility but a ton more speed, flash and RAM! The UNO R4 comes in two flavors, the Minima (https://www.digikey.com/short/r70jbj93) is low cost, only $20, whereas the UNO R4 WiFi (https://www.digikey.com/short/qj072pnm) is $27.50 and adds WiFi and BLE via an ESP32-S3 plus a cute monochrome LED grid for scrolling messages or displaying status icons.
This pair of dev boards look just like those classic Arduino boards you probably learned to code and hack on, they've been around for almost 20 years, the first board looked very similar, but had a RS232 serial port instead of USB, and all through-hole components (https://blog.arduino.cc/2021/12/09/one-board-to-rule-them-all-history-of-the-arduino-uno/). Through various iterations and improvements, the original board was redesigned to add USB and update to the ATmega168 with the Diecimila (https://docs.arduino.cc/retired/boards/arduino-diecimila) and then the ATmega328 plus auto-power-switching Duemilanove (https://docs.arduino.cc/retired/boards/arduino-duemilanove) in 2009. In 2010 the most popular Arduino to date was released, the UNO, which updated the USB port to use an ATmega16u2 and through various small revisions added the IOref pin to allow 3V power/logic and separate I2C pins since A4/A5 were no longer always connected to a TWI peripheral.
Since about 2012, which was the release date of the UNO R3, not a lot has happened with that particular configuration/shape. Arduino the company has released a ton more boards but in different form factors, all available at DigiKey: Nano, Due, MKR, Portenta etc. (https://www.digikey.com/en/supplier-centers/arduino) and you should definitely check them out! But it's also a big deal when the main workhorse of the family gets a respin. Particularly since the new R4 takes a very different direction than the previous UNOs: instead of just upgrading the atmegaxx8 chipset, Arduino has gone with the totally different ARM Cortex-based RA4M series which we've covered on a previous EYE ON NPI (https://blog.adafruit.com/2023/05/25/eye-on-npi-renesas-ra4m1-microcontroller-series-eyeonnpi-digikey-renesasglobal-digikey-adafruit/) In that video we covered a lot about the chip itself so check it out if you're interested in the specifics of that chip family.
The chip itself is a similar family to the ARM Cortex M0-based SAMD21 'Arduino Zero' (https://store-usa.arduino.cc/products/arduino-zero?selectedStore=us) but thanks to the Renesas version of this core, we now get the 5V-run RA4M. From Arduino's description, here are some of the updates: - Hardware compatibility with UNO form factor: The UNO R4 Minima maintains the same form factor, pinout, and 5 V operating voltage as its predecessor, the UNO R3. This ensures a seamless transition for existing shields and projects, leveraging the extensive and unique ecosystem already established for the Arduino UNO. - Expanded memory and faster clock: Prepare for more precise calculations and the ability to handle complex projects with ease. The UNO R4 Minima boasts increased memory and a faster clock speed, empowering you to tackle demanding tasks effortlessly. - Extra on-board peripherals: The UNO R4 Minima introduces a range of on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP. These additional components provide you with expanded capabilities and flexibility in your designs. - Extended 24 V tolerance: The UNO R4 Minima now supports a wider input voltage range, allowing power supplies up to 24 V. This enables seamless integration with motors, LED strips, and other actuators, simplifying your projects by utilizing a single power source. - SWD connector: Debugging is a critical aspect of any project. Simply connect an external debugger to the UNO R4 Minima and effortlessly monitor the inner workings of your system. Stay in control and gain valuable insights. - HID support: The UNO R4 Minima comes with built-in HID (Human Interface Device) support, enabling it to simulate a mouse or keyboard when connected to a computer via a USB cable. This convenient feature makes it a breeze to send keystrokes and mouse movements to a computer, enhancing usability and functionality.
At $20 a piece, these new Arduino UNO R4s (https://www.digikey.com/short/qj072pnm) are a great price for the high quality you get from Arduino - and there's lots of them in stock at DigiKey for immediate shipment! Grab both the UNO R4 Minima (https://www.digikey.com/short/r70jbj93) and UNO R4 WiFi (https://www.digikey.com/short/qj072pnm), and they'll ship immediately so you can get started moving your 8-bit micro projects to Cortex-M4 by tomorrow afternoon

Welcome, fellow makers, to a world where magic and technology intertwine. Today, we embark on a journey to build a dress that seems to shimmer and flow like a cascading stream, as if it were touched by enchantment.
To bring this magical illusion to life, we will harness the power of NeoPixel LEDs, the wondrous gems of the electronics realm. With their ability to glow in a multitude of colors, they will paint the illusion of water in motion, as if from a fountain of dreams.
To command this luminous symphony, we turn to Arduino, the sorcerer's wand of the DIY world. With a dash of code, we will orchestrate the dance of the NeoPixels, making them flicker and flow, crafting an everlasting illusion of water in motion.
Your quest begins at learn.adafruit.com. Unleash your creativity and weave the fabric of magic with NeoPixel LEDs and Arduino code. Let this tutorial be your guide, and may it spark the flames of inspiration as you journey into the realm of enchanting DIY electronics.

This week we're working on reviving our old floppy hacking projects by making a dev board that will let us connect to various old-school disk drives to either control or emulate them (https://github.com/adafruit/Adafruit_Floppy).
These devices used lots of motors and solenoids to spin and eject the discs, so we will need to be able to provide them with a good amount of current.
For 3 1/2" floppy drives, 5 Volts at 1 Amp or so is not unusual, and we expect larger disk drives may need even more power. For the other motors, we'll want to have a 12 V power supply input, so we need to convert 12V to 5V, and at these currents, an LDO like the 1117-series (https://www.digikey.com/short/z8vtf00m) will have to dissipate way more heat than we'd be able to get rid of - that's when a buck converter is a great alternative.
Let's find a powerful and affordable converter that can provide 2A or more.
See the chosen part on DigiKey https://www.digikey.com/short/4wfzc22j

This week's EYE ON NPI packs quite a punch, it's the powerful TI TPS61033 Fully-Integrated Synchronous Boost Converter (https://www.digikey.com/en/product-highlight/t/texas-instruments/tps61033-synchronous-boost-converter), a souped-up DC/DC regulator with a generous 5.5 A internal switch, in a tiny SOT package. This chip will chomp through your power generation needs, with a specialty at boosting Li Ion / LiPoly batteries to 5V at up to 2 A continuous current.
The TI TPS series (https://www.digikey.com/short/m345b8wt) of boost converters is well-known here at Adafruit, they're the basis for our popular PowerBoost series of boards (https://www.adafruit.com/search?q=powerboost) - all-in-one switching converters that will take a LiPoly battery in and give you 5V out for making charging phones or dev-boards easy. We've been using the TPS61090 (https://www.digikey.com/en/products/detail/texas-instruments/TPS61090RSAR/566911) on boards like the PowerBoost 500 (https://www.adafruit.com/product/1903), that has an internal 2 Amp switch. For the PowerBoost 1000 (https://www.adafruit.com/product/2030) we go with a TPS61030 (https://www.digikey.com/en/products/detail/texas-instruments/TPS61030RSAR/610198), with an internal 4A switch. Synchronous boosters with internal switches help engineering in three ways: disabling the chip fully disconnects the output and input without having to worry about the conducting body diode of a FET, it reduces BOM costs because there's two/three fewer components to worry about, and of course it makes layout easier and smaller.
For a while, we've had folks ask for a PowerBoost 2000: a board that will take Lipo input and provide 2A output, which would let it easily power single-board computers like a Raspberry Pi 4. Finally there's a chip that will do the job! The TI TPS61033 (https://www.digikey.com/short/vt3wj7t7) really is a fully-integrated synchronous boost converter, only a few passive components are required: input and output bulk capacitors and, of course, an inductor. If you want to operate at 5V fixed output, you don't even need a feedback resistor divider! And, it's in a tiny package compared to the TPS610x0 chips, with thoughtful pin ordering so you can lay out the PCB on 2 layers with chunky fat copper pours to reduce inductance and act as a heat sink. The datasheet specifically steps through component selection for making a 5V 2A output from single cell battery using a 4x4mm 1uH inductor so we're pretty confident that this would make a great PB2K.
If you have a rechargeable battery project that needs 5 V output and you want to go with a rock-solid booster that can provide 2 Amps of current, the TI TPS61033 Fully-Integrated Synchronous Boost Converter (https://www.digikey.com/short/vt3wj7t7) will make you jump for joy. Best of all, it's in stock! Thousands of them! All at DigiKey for immediate shipment. Order today and DigiKey will pack them up and send them off tonight so that you'll be boosting your batteries by tomorrow afternoon.

The Great Search - SMT Screw Terminal Blocks https://www.digikey.com/en/product-highlight/t/te-connectivity-amp/board-mount-reflow-terminal-blocks
This weeks' Great Search comes to us from social medial, where Jeremy S Cook asks: "Anyone know where I could find surface mount screw terminals?" (https://twitter.com/JeremySCook/status/1680208303870074880) We're glad you asked! This is something we've had to deal with, since we like to have solder-less designs but want to avoid using the selective solder machine or hand soldering for just 2 points. We've used Wago SMT terminal blocks on boards like the Bonsai Buckaroo (https://www.adafruit.com/product/4534) and STEMMA relay breakout (https://www.adafruit.com/product/4409) - the latter board we also wanted to avoid having contact terminals that were exposed in case folks were using mains power. However, these are push terminals, and they specifically want screw-tightening terminals. Does such a thing exist? Tune in to find out!

This week on EYE ON NPI, we are keeping an eye on safety with Infineon's 170 W AC-DC Charger Design for E-bikes and Power Tools (https://www.digikey.com/en/product-highlight/i/infineon/170-w-ac-dc-charger-design-for-e-bikes-and-power-tools) featuring the Infineon XDPS2201XUMA1 (https://www.digikey.com/short/h3qfmvc0) digital flyback controller and Infineon IPA60R280P7SXKSA1 (https://www.digikey.com/short/cfvp4f82) 600 Volt, 12 Amp N-Channel power MOSFET. These two best buddies can join forces to help you quickly and safely charge big battery packs such as in e-Bikes and other micro-mobility devices (https://wagner.nyu.edu/rudincenter/areas-focus/micromobility).
If you live near any density of folks, and in a place with well-paved roads, you've certainly noticed the increase in e-Bikes, e-Scooters, mono-wheels and other electric 'person-movers'. In NYC we've seen these go from banned to bountiful, as COVID restrictions made food and grocery delivery a bigger business than ever (https://nymag.com/intelligencer/2022/01/a-simple-solution-for-getting-cars-off-the-road-right-now.html). They're also popular in lots of countries where folks may not be able to afford cars, motorcycles or even mopeds: an entry-level E-Bike can go for $1000 to $3000 - which is a lot of money but much less expensive than a car. Plus you don't have to pay for gas or parking, you can lock it up outside or in your yard and charge it over a 120V power plug.
But, about that charging setup ... these light vehicles (https://www.infineon.com/cms/en/applications/automotive/light-vehicles/) use very big batteries: a common 48V 250 Watt-hours is 26 18650 sized batteries connected in series - with extremely high discharge pulses necessary if you want to haul around a 75 lb bicycle plus a 200 lb cargo of human plus groceries. Also important is the ability to charge quickly. If you're using the e-Bike for a courier job, or you take it work, and you need to charge it in order to get back home, you don't want to wait around 16 hours. But that also means that bicycles are often charged unattended, and that could mean that a poor engineering job on the charging circuit can lead to tragedy (https://www.theatlantic.com/technology/archive/2023/07/e-bike-battery-lithium-ion-fire/674622/). So don't cheap out on your design, and don't try to invent high power electronics layouts and specifications when you can rely on experts who've already done the work and created a reference you can base your product on (https://www.digikey.com/en/product-highlight/i/infineon/170-w-ac-dc-charger-design-for-e-bikes-and-power-tools)

We are gettin' really really close to putting the new Matrix Portal S3 https://www.adafruit.com/product/5778 into the shop, here's a tester we use to burn in the self-test code. The RP2040 brains https://github.com/adafruit/RP2040-Based-Tester-Brains-PCB resets the S3 into the ROM bootloader, the sends over compressed binaries via USB. when the self-test starts up it notices that it's in the test jig and performs a self test of the GPIO and voltages. once done, it turns into a demo board that has a basic matrix display output for users to verify functionality. This way we only have to program the board once!

The RA8875 is a nifty chip that can do SPI to 24-bit TTL display, up to 800x480! https://www.adafruit.com/product/1590 this breakout is an older design and with many parts no longer available, we had to do a respin to change the backlight driver from a FAN5333 to another high-output constant-current LED string driver https://blog.adafruit.com/2022/08/02/the-great-search-white-led-strand-backlight-constant-current-driver-fan5333-replacement-thegreatsearch-digikey-adafruit/ and while we were there we also updated the MISO pin to be tristate-d via a 74AHC1G125 so that you can share the SPI port with other chips - that was a request from over a decade ago that linged on my todo list. but it's done now :)

This week's EYE ON NPI is going to Matter a lot to you if you're interested in integrating with the world of IoT devices and sensors that is converting on us, inside the home and out in the world...It's the Silicon Labs MG24 Series of development boards (https://www.digikey.com/en/product-highlight/s/silicon-laboratories/mg24-development-kit) - featuring the Silicon Labs EFR32MG24 series of chips (https://www.digikey.com/short/00892bvf), designed for use with Matter (https://en.wikipedia.org/wiki/Matter_(standard)) an open-source connectivity standard for smart home and Internet of Things devices from the Connectivity Standards Alliance (https://csa-iot.org/) formally the ZigBee Alliance. The EFR32MG24 chips (https://www.digikey.com/short/f8z8rbvn) are fully featured Cortex M33's with tons of peripherals, timers, and of course, a 2.4GHz radio that can be programmed to operate as a ZigBee device. That makes it perfect for use in designing low cost, low power, home automation devices that don't need the power and complexity of WiFi.
These transports live on the lower 'levels' of the 7 Layer OSI Model (https://en.wikipedia.org/wiki/OSI_model) Each family of home devices comes with their own transport, and often they come up with their own custom application layer as well. This means that you can't use something made for Alexa with HomeKit unless the developer programmed both. It's caused fragmentation and utter frustration when someone buys a smart light bulb or HVAC controller just to find out that its walled off from the rest of their devices. The goal of Matter is to unify the upper layers (https://developers.home.google.com/matter/primer) so that devices can be discovered and controlled by any kind of hub: from a DIY Raspberry Pi to an official device from Apple, Google/Nest, Meta, or other - much like you can use your Windows desktop or Android phone to view a website designed on a Mac, and hosted on Linux.
The biggest companies in this space, Amazon, Apple and Google, have already signed on to make sure that their products adhere to Matter's API (https://csa-iot.org/members/). You, the engineer tasked with creating the next new product line for your company, should be interested in whether or not this "Matters" to you. The good news is that joining an ecosystem means you can make a small device that competes in a 'big playground' of sensors, voice agents, automation tools, and gateways. (https://pages.silabs.com/rs/634-SLU-379/images/Matter_Certification_The_Value_it_Brings_to_IoT%20Devices.pdf) But need to play nicely with the others - not scream in kids' ears, errr... overwhelm the share spectrum resource. We also have to let every device have a turn at commands, and not interfere with their behavior. Thus, Matter certification! Silicon Labs has a white paper on Understanding The Path to Certifying Your Matter Devices (https://www.silabs.com/whitepapers/how-to-certify-matter-devices)
Moreover you can get started immediately by picking up one or two of Silicon Labs' MG24 development kits (https://www.digikey.com/short/0rc3n5f7) for less than $40 and you can begin immediately with developing on the EFR32MG24 (https://www.digikey.com/en/products/base-product/silicon-labs/336/EFR32MG24A010/629647) a well-documented, low-power friendly chip with built in 2.4 GHz radio. Inside is a Cortex M33 running at 78 MHz, with 1.0 to 1.5MB of flash and 128 to 256KB of SRAM (https://www.digikey.com/short/f8z8rbvn) so it's got plenty of room to handle multiple protocol stacks, security layers and any RTOS or Matter layers. SiLabs has been making radio-inclusive chips for many many years, so you know that there will be great support and documentation. We also have the beginnings of a CircuitPython port for this chip (https://circuitpython.org/board/sparkfun_thing_plus_matter_mgm240p/) although at the time of this writing there is not Matter support built in, it would still be very helpful for bringing up a development board and verifying hardware.
Want to take Matter into your own hands? DigiKey has you covered here: the XG24-EK2703A Explorer Kit (https://www.digikey.com/en/products/detail/silicon-labs/XG24-EK2703A/17051436) is a great starting point with USB, mikroBus-compatible GPIO headers, debug port, and Qwiic/QT port. (https://www.digikey.com/en/videos/s/silicon-labs/mg24-development-kit-datasheet-preview) For final integration, you can also pick up raw chips such as the Silicon Labs EFR32MG24A010F1536IM48 (https://www.digikey.com/short/07qww54q) or integrated modules (https://www.digikey.com/short/3n4rp9dt) that have passives and antenna wired up for quick usage. All are in stock for immediate shipment - order today and DigiKey will deliver to you Matter on a silver platter by tomorrow afternoon! Follow it up by watching the DigiKey + Silicon Labs webinar on Matter development and certification (https://event.on24.com/wcc/r/4241172/CE3FB2F9DB2D54D5A47A124701A93047) to get your product out the door ASAP.
This week we’re paying homage to one of our personal faves, the Metro M4! https://www.adafruit.com/product/3382 https://www.adafruit.com/product/4000 https://www.adafruit.com/product/4084 https://www.adafruit.com/product/4064

We're slowly but surely trying to de-SAMD51'ify our product line since that chip has a 2024 ETA. a bummer because we really loved that chip but it's probably a good time to transition since it can be a year until we get some and even then, the dates have been pushed multiple times. so, first up is the matrix portal m4 https://www.adafruit.com/product/4745 ! instead of a samd51 + esp32, we've got a version with ESP32-S3 WROOM which has 8MB of flash, and 2MB of PSRAM. the S3 has a nice peripheral that can be used to drive these matricies very fast, and the 2 MB of PSRAM will make this possible to drive lots of panels! we kept the same outline shape and functionality, including the built in accelerometer, which makes this LED sand demo a quick port.

Build a Magikoopa Wand with Adafruit’s New RP2040 PropMaker Feather.
Guide: https://learn.adafruit.com/mario-magic-wand
We designed and 3D printed a magic wand inspired by the Super Mario Brothers movie. It’s got motion activated lights and sound with a spinning crystal gem.
This new Feather is an all-in-one dev board that features an I2S amp, accelerometer, NeoPixel driver, Servo Header Pins, STEMMA QT and screw block terminals.
It’s got the RP2040 chip with 8MB of SPI flash, 21 GPIO pins, and lipo battery charging over USB-C.
With CircuitPython, the board acts like a USB drive so you can easily customize the code with just about any computer.
You can modify the code to fit your project, just change the values such as the NeoPixel color, speed or the accelerometer threshold.

this seesaw board converts 4 rotary encoders to I2C for adding a ton of twists. like our other attiny8xx boards, we use a metro m0 to do the programming of the UPDI interface, then communicate over I2C to check each pin is not shorted or open. this will be in the shop soon so don't get your knickers in a twist! https://www.adafruit.com/product/5752

nothing is as satisfying as a scoop mint chocolate-chip on a hot day...except maybe finishing a board design from 2020! this ZED-F9P is an RTK 'real time kinematics' board https://blog.adafruit.com/2020/06/08/eye-on-npi-u-blox-c099-f9p-application-board-for-zed-f9p-gnss-rtk-module-eyeonnpi-adafruit-digikey-digikey-ublox/ that can do high precision location. kinda like a GPS/GNSS but with centimeter accuracy. they're not cheap but there's really nothing else that works as well. these are modules from uBlox and they're finally in good supply at DigiKey https://www.digikey.com/short/8v5rjw15 . our shield design is nice and spacious and would be a great fit for a Metro ESP32-S2 https://www.adafruit.com/product/4775 which has DC, USB and LiPoly input. we'll be sending out for prototype PCBs this week!

For our new Metro RP2040 design, we're making sure that the board can be powered by either USB Type C 5V, or DC wall adapters. While it's common to have 5V USB power almost everywhere, DC power is still useful for when you want 12V to also drive a motor or LED strip. In such cases, we'll use a 5.5 / 2.1mm DC jack to allow the most-common-sized plugs to work.
These jacks come in a few common configurations, and have different power ratings and usage cases - even though they all look the same! We'll find a few good options and chat about what to look out for.

we just got our UNO R4 WiFi, featuring the Renesas RA4M1 series of chips https://blog.adafruit.com/2023/05/25/eye-on-npi-renesas-ra4m1-microcontroller-series-eyeonnpi-digikey-renesasglobal-digikey-adafruit/ an ESP32 wifi co-processor, an adorable LED grid, and a JST SH 4-pin connector...a.k.a a Qwiic port! Yay it is so great to see this connector becoming standardized on so many platforms. It means that all of our STEMMA QT devices https://www.adafruit.com/category/1018 will work plug-and-play. Here we're testing it with an OLED https://www.adafruit.com/product/938 and SHT41 breakout https://www.adafruit.com/search?q=sht4 we only had to update our demo to use Wire1 instead of Wire, since the secondary I2C bus is used for this connector. No soldering required!

@Arduino @RenesasPresents
Sometimes you've got something with USB host, like a embedded linux board, and you want to connect more than one thing. or maybe you want to turn something like a keyboard into a multi-device USB peripheral. this usb hub board will do that for you! it features an SL2.1 USB 2.1 hub chip which converts one port into four. we have either 0.1" header or USB C for the upstream, and then 4 x 4-pin ports for peripheral connections. to test it out we're using our 'simple' USB-breakout cables https://www.adafruit.com/product/4449 that just give the 5V/D+/D-/GND pins on wires for quick testing. all is good, this is ready to order!

Buck-Boost Converters are power supplies that are 'ambidextrous' - they can convert lower or higher voltages to one steady output. A good idea for if, say, you have something that could be powered by USB or two AA's but you want 3.3V output. Much like the name implies, they can both 'buck' the voltage down, and 'boost' the voltage up.
For our Toy Hacker board, let's try to find a low cost buck-boost chip that will give us about 500mA of 3.3V output even from two nearly-dead AA batteries that are 0.9V. We want something somewhat small and fairly inexpensive, efficiency isn't the most important since we expect folks to use rechargeable AAs anyhow.

This week we got the prototypes for our 'Toy Hacker' board that replaces the innard of a Baby Einstein take-along-tunes toy with our own tronix. we picked the esp32-s2 as a main core because it has wifi baked in, perfect for when you have a device that is fully enclosed like this one! using the CircuitPython WiFi workflow, we configured the wifi credentials and access password in settings.toml and it pops up on our network. now we can edit code, move files around, etc, without having to undo all those lil screws. This may very well be the first python powered baby toy! Current song as requested by our beta tester (Baby!) is Taylor Swift - You Need To Calm Down ...

with most of our dev boards, sensors and feathers now sporting plug-and-play stemma QT ports (https://learn.adafruit.com/search?q=stemma%2520qt) it can be very fast to put together projects with half a dozen boards snapped together. But now you don't have a breadboard as a mechanical substrate... which is why jepler and scott collaborated on this nifty swirly grid design. originally 3D printed, we decided to upgrade these to an 'aluminum PCB' - note there's no actual copper on here, its just the aluminum backing, and then black soldermask with silkscreen. each square is 0.6 inch x 0.6 inch and there's holes every 0.2 inches. with the various dots and dashes you can pretty much make anything on a 0.1" grid fit. here's our demo to test it out. the aluminum is easy to cut/drill/machine/bend if you need more customization. coming soon to the adafruit shop!

this viral retro mini laptop just appeared on our desk, we ordered it about a month ago and its just as cute as you expect! with a modern TFT display and keyboard and USB disk interface, but still rockin the classic 8088 chipset (https://en.wikipedia.org/wiki/Intel_8088) - its a perfect experimentation platform for very old software. i love the reuse of these 90's datecoded chip. we got one of our old 512MB SD cards (https://www.adafruit.com/product/5252) to plug in for data transfer and have it running Spectrum Holobyte Tetris (https://www.myabandonware.com/game/tetris-dj). any recommendations of software we should try running? it won't be able to run doom - that requires a later chipset!

This Great Search is by special request! Viewer 2231puppy has asked us to find them a part on DigiKey and we're happy to oblige! They tweeted: "@adafruit If you haven't already picked out a category for The Great Search tonight, I'd love to see one on analog hall effect sensors for detecting magnet proximity. Thanks!" ( https://twitter.com/2231puppy/status/1668000481686290433)
No problem, there's thousands of magnetic sensors available, with different outputs and configurations. Let's go looking for one with analog/ratiometric output, wide power voltage range, and through-hole packaging for quick prototyping - We'll show you how to find the perfect one on DigiKey tonight!

The Great Search - Single Channel 3V to 5V level shifter
https://www.digikey.com/en/products/detail/diodes-incorporated/74AHCT1G126SE-7/2711993
On our new Prop-Maker Feather we like to do a 'favor' to our users by level shifting the NeoPixel signal from 3.3V to 5V. We don't always need this but some NeoPixel chipsets are a little finicky about the levels, especially if you have a 5.5V or 6V power line on the NeoPixels. We'll use a single buffer, and it needs to be small, so we'd like a tiny package. We'll also review the 74 series logic family (https://en.wikipedia.org/wiki/7400-series_integrated_circuits) to verify what series we want to filter out when we search on DigiKey for this part.

This week's EYE ON NPI passes the vibe check - it's Vybronics' Rectangular LRA Vibration Motor (https://www.digikey.com/en/product-highlight/v/vybronics/rectangular-lra-vibration-motor) and friends - a series of linear resonant actuators, AKA LRA, used to create vibration/haptic feedback.
Haptics (https://en.wikipedia.org/wiki/Haptic_technology) were first used in airplanes - where originally there was a mechanical connection between the pilot controls and the plane steering. That is, when turning or tilting the yoke, it would mechanically control any flaps (https://en.wikipedia.org/wiki/Aircraft_flight_control_system). However, that means that the pilot would have to be strong enough to move the flaps while also keeping track of all the different controls needed - a recipe for disaster because a tired or confused pilot could make a catastrophic mistake! So, instead, the control of aircraft turned to hydro-mechanical and then servo-electrical. You might see the same on modern cars: instead of the steering wheel directly controlling the tire angle, it now send a signal that is interpreted by motors that do the actual movement, also known as Drive by wire. (https://en.wikipedia.org/wiki/Drive_by_wire)
The trade-off with drive or fly-by-wire is that there's less need for strength and speed by the person in the cockpit - but they do lose the mechanical feedback that would normally be fed back through the mechanical linkages. That feedback is important because it allows you to feel when something might be blocking or fighting against the motion - in planes you can tell the airspeed and the craft's stress level. Sure you can put this information in a gauge of some sort but it requires the operator to look and interpret a number when the feeling is more intuitive. Thus the invention of force feedback or...haptics!
Haptics have been tirelessly used in automotive and aircraft for decades, when in the 90's they had a bit of a resurgence as part of VR interfaces. If you're in a 3D rendered virtual world, you want to feel when you bumped into something or grabbed an item successfully. For gaming, an early form of 'play by wire' we've moved from the 1994 Aura Interactor (https://en.wikipedia.org/wiki/Aura_Interactor) to being included in almost every game controller, like the 1997-released N64 Rumble Pak (https://en.wikipedia.org/wiki/Rumble_Pak) and Playstation DualShock (https://en.wikipedia.org/wiki/DualShock) as vibrational feedback when moving or taking damage.
Mobile devices are also big users of haptic feedback - originally as vibration alert for 'silent mode' - but now also for typing and UX feedback. For vibration feedback, a basic ERM motor such as the Vybronics VZ43FC1B5640007L (https://www.digikey.com/en/products/detail/vybronics-inc/VZ43FC1B5640007L/12323649) will do fine - turn it on to cause a vibration that can be detected even when the phone is in a bag or pocket.
But if you want to have 'sharper' feedback, these ERMs aren't as good because they take time to turn on and get up to speed. So they're good for big motion but not quick motion. That's when you want to use LRAs - Linear Resonant Actuators. (https://www.digikey.com/en/product-highlight/v/vybronics/rectangular-lra-vibration-motor)
Vybronics makes a wide range of LRA vibration motors (https://www.digikey.com/en/supplier-centers/jinlong-machinery) in addition to their wide range or ERM's. You can select from different sizes - larger ones will of course have a stronger feedback response, but will require more energy and size. ERM's are really easy to drive: provide a positive DC voltage and the motor starts moving. LRA's are harder to control, you will need an AC waveform to kick-start the resonant motion. (https://www.vybronics.com/lra-assembly-drawing)
Our favorite driver is the TI DRV2605 (https://www.digikey.com/en/products/detail/texas-instruments/DRV2605LDGSR/5014144) which we even have a breakout board (https://www.digikey.com/en/products/detail/adafruit-industries-llc/2305/5356831) to make it easy to connect up to a Vybronics LRA. The DRV2605 even comes with a wide range of built-in waveform actions (https://www.ti.com/lit/ds/symlink/drv2605.pdf) to make integration very easy. Vybronics also has some examples of how to mount their motors with PCB contacts to allow the motor to vibrate within a cavity.(https://www.vybronics.com/mounting-with-spring-contacts)
Vybronics' Rectangular LRA Vibration Motors such as the VLV152564W (https://www.digikey.com/en/products/detail/vybronics-inc/VLV152564W/19203005) will make the vibe right in your product that requires tactile haptic feedback to improve your user experience. With their small cases and high strength, they'll turn glass touchscreens and capacitive touch buttons into something that feels like a mechanical control surface. Order today and DigiKey will ship your motor instantly so that you can be tick-tack-bzzt'ing your way to a haptic cyber-future by tomorrow afternoon.

This week's EYE ON NPI is enjoying the beautiful weather with you, whether sitting in the sun or lounging in the shade - all's good because we've got Nexperia's NEH2000BY Energy Harvesting Power Management IC with embedded solar MPPT capability! (https://www.digikey.com/en/product-highlight/n/nexperia/neh2000by-energy-harvesting-power-management-ic) This tiny, low-cost chip is a one-stop solution for extending the life of your product by making it powered by small solar cells.This chip is perfect for wearables or miniature sensor nodes, maybe with a LoRa radio, WiFi or Bluetooth Low Energy where space and pricing is important. For example, an asset tracker, traffic monitor, activity watch, or agricultural sensor network: stuff that is outside anyways so it'll be designed for outdoor use and have lots of sun exposure. We've covered other MPPT tracking solar harvesting chips (https://blog.adafruit.com/2021/04/23/eye-on-npi-max20361-tiny-single-multi-cell-solar-harvester-maximintegrated/), and the NEH2000BY has some advantages in size, cost and simplicity. Either use it to increase the time between charges, or use it to have your product be fully encased with no need for charging at all, thanks to the power of the SUN (https://solarsystem.nasa.gov/solar-system/sun/galleries/?page=0&per_page=25&order=created_at+desc&search=&href_query_params=category%3Dsolar-system_sun&button_class=big_more_button&tags=sun&condition_1=1%3Ais_in_resource_list&category=51)The Nexperia NEH2000BY energy harvester (https://www.digikey.com/short/hpnfttw3) is designed specifically for use with solar cells because cells collapse under high current draw - which is what batteries want when they are charging up so that they can be ready to go ASAP! When drawing current from a solar cell, at the very beginning the voltage is very high, then is slowly drops down as more is drawn until the input voltage collapses completely. So you have to be very careful when drawing current - too little and you lose out on efficiency, too much and your power goes away completely.There's a 'sweet spot' right in the middle, where you can get the most power output, which is called the Max Power Point. (https://en.wikipedia.org/wiki/Maximum_power_point_tracking) And this point varies with how much sunlight you get - so it isn't something you can pre-program in with a comparator or anything. Instead, the energy harvester has to wiggle the power draw forward and back to find the maximum point. For large-scale solar installations, you'd have a microcontroller do the math for you, and adjust throughout the day - it isn't hard to do MPPT it just takes measurement and computation. But in small and low-current situations, you can't spend all your power budget on a microcontroller to manage your battery charger.First up, almost no extra components are needed: just a stabilization capacitor plus a capacitor for the switched-cap boosting doubler. Note that there's no inductor because it seems to use a switched-cap boosting method for approximately 2x voltage output - so you will need to spec a panel that, when the MPPT voltage is approximately doubled, you'll have about 0.3V above the battery voltage. There's some math in the datasheet to work this out but basically in the end, use a panel with an open-circuit voltage - Voc - that is about 0.7 times the battery voltage. So, e.g. if you're using a Lipoly (https://www.digikey.com/short/h02tmj1q), with a VBat of 4.2V, use a 3V solar panel - which is very common and inexpensive. For NiMH cells, add up the total series voltage before multiplying by 0.7 for the Voc desired. To keep your battery from over-charging, either use a separate battery charger chip that will do the constant-current to voltage-limited charging, or use a low cost over-voltage protection (OVP) chip as recommended in the datasheet.If you'd like to integrate the Nexperia NEH2000BY Energy Harvesting Power Management IC (https://www.digikey.com/short/hpnfttw3) into your next solar-powered product, thank your lucky stars because DigiKey has the NEH2000BY in stock right now at a great price for immediate shipment. With the long summer days ahead, you can order today and be max-power-point'ing before the sun sets tomorrow.

3Com's Ergo Audrey was an internet appliance, released in 2000 and discontinued 7 months later. Designed by Don Fotsch and Ray Winninger, Audrey was intended to be part of a family of devices, each serving a specific room in the house. The kitchen was their initial focus "Internet Snacking" - lightweight web browsing in a home setting.Audrey had a touchscreen LCD interface and came equipped with a stylus. It was powered by a 200 MHz Geode GX1 CPU, with 16 MB of flash ROM and 32 MB of RAM, a modem, two USB ports, and a CompactFlash socket for connectivity. Available in colors like "linen", "meadow", "ocean", "slate", and "sunshine".Named in honor of Audrey Hepburn. 3Com discontinued Audrey in June 2001. The hardware hacker community embraced the leftover Audreys, discovering exploits and modifying the device for their own needs.Despite its short lifespan, Audrey's innovative design and functionality made it a unique piece of internet appliance history.https://en.wikipedia.org/wiki/3Com_Audrey#3Com #3ComAudrey #InternetAppliance #RetroTech #Retro

This week's EYE ON NPI is Big In Japan, it's the Renesas RA Microcontroller Series (https://www.digikey.com/en/product-highlight/r/renesas/ra-mcus) available at DigiKey in a wide range of sizes and configurations. With the chip shortage easing up, it's a great time to look at what chips to use for your next design. And while we have covered a ton of Arm Cortex microcontrollers on EYE ON NPI (https://blog.adafruit.com/?s=eye+on+npi+cortex), we haven't yet taken a look at Renesas' RA offerings.Renesas is a company created by the merging of the silicon design groups from Hitachi, NEC and Mitsubishi Electric (https://www.youtube.com/@RenesasPresents), so not surprisingly it's very Japanese-focused and used a lot in Japanese electronics companies but not as often in the USA. However, it's always good to have more competition and with the Arm Cortex standard, it's easy to move from one chip vendor to another without having to do a lot of re-targeting. So let's take a look!We saw Renesas highlighted over on DigiKey (https://www.digikey.com/en/product-highlight/r/renesas/ra-mcus) and the same day also received our new Early Access Arduino UNO R4 Minima (https://store.arduino.cc/pages/unor4) for us to use in making sure all our libraries work. The UNO R4 is the long-awaited upgrade to the popular R3 (https://www.digikey.com/en/products/detail/arduino/A000073/3476357) which came with an 8-bit, 16 MHz, 16 KB Flash, 2KB SRAM chip. While Arduino has come out with many other dev boards since then, the UNO hadn't got an update to 32-bit in a while. The challenge? Finding an affordable 32-bit chip with native USB, Cortex M3 or M4, good software SDK and 5V compatibility. That last part is the hardest, for example there's no ATSAM chip that has both USB and 5V compliance.An acquaintance just came back from a holiday in Japan and she mentioned that "everything is just...a little better there than here in the US!" and that's how we felt when looking at the RA4M1 datasheet (https://www.renesas.com/us/en/document/dst/renesas-ra4m1-group-datasheet)The RA4M1 series is a great pick for an 8-bit upgrade. The core is a Cortex M4 which means you're going to get good speedy computation with built in floating point and DSP instructions. For flash memory, 256 KB stores your code and there's a separate 8KB "EEPROM" like section. For RAM, 32 KB is available. It's got all the peripherals you expect such as timers, DMA, ADCs, USB full-speed, I2C, SPI, and UART as well as some upgrades you can't get on 8-bit chips. For example, the ADC is 14 bits, and there's also a 12-bit DAC. There's 4 internal op-amps and 8 total timers! There's two I2Cs, SPIs and UARTs and also CAN bus. A built in RTC is a true real time clock, with battery backup. There's also capacitive touch sensing and a segment LCD controller - our friend Joey Castillo will love that! (https://www.joeycastillo.com/objects/lcdwing/).In addition - we also saw some really beautiful silkscreen board designs for the Renesas Gadget Series (https://www.renesas.com/us/en/products/gadget-renesas) as well as an online code editor for compiling for the chip series. (https://www.renesas.com/us/en/products/gadget-renesas/boards/gr-sakura/project-sketch-on-web-compiler) We're hoping some of that work gets revitalized with the many makers folks who will be hacking with the R4.If you can't wait to try the Renesas RA4M1 (https://www.digikey.com/short/wt4b872q) chip out, Digikey has an affordable RA4M1 dev board in stock (https://www.digikey.com/short/3qzr0bbw) which comes with a J-Link on-board debugger with separate USB port, a few onboard peripherals, current sensing jumpers, and tons of GPIO so you can prototype your design quickly. Once you've got your design sorted out, chips are available for immediate shipment in TQFP (https://www.digikey.com/short/f3m2pffz) and QFN (https://www.digikey.com/short/fn2m9bbm). Order these from DigiKey and you will say "Konnichi wa" (https://en.wikipedia.org/wiki/Konnichiwa) to a new family of microcontrollers by tomorrow morning.

now that we can get chips we're churning out seesaw boards to help with all sorts of common needs - like this I2C to NeoPixel driver converter that uses an attiny816 https://www.digikey.com/en/products/detail/microchip-technology/ATTINY816-MFR/6555812 . it's a 'no solder' way to add NeoPixel support since you can use the pre-attached terminal blocks. we've got our UPDI in-situ programmer https://github.com/adafruit/Adafruit_AVRProg running on a Metro M0 https://www.adafruit.com/product/3505 which can set the fuses and burn the firmware so fast, we have plenty of time to take a drive around the adafruit factory.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #neopixel #babybumpercar
Zener diodes (https://blog.adafruit.com/2013/07/17/your-moment-of-zener/) really are amazing little devices, useful for a dozen different circuits. (https://www.evilmadscientist.com/2012/basics-introduction-to-zener-diodes/) We like to use a Zener clamp (https://ww1.microchip.com/downloads/en/DeviceDoc/chapter%208.pdf) as a basic method of protecting analog inputs on some of our dev boards so you can plug 5V in by accident and nothing bad will happen to the chip GPIO.They're available in just about every voltage setting - let's check out some tips on using Zeners, (https://www.onsemi.com/pub/Collateral/HBD854-D.PDF) what to watch out for when specifying them and all the different packages available at DigiKey.

This week's EYE ON NPI will get you designing IMUs #LikeABosch (https://www.bosch.com/stories/like-a-bosch/) with the Bosch Sensortec BMI323 Inertial Measurement Unit (https://www.digikey.com/en/product-highlight/b/bosch-sensortec/bmi323-inertial-measurement-unit). A low cost, but high precision 6-axis inertial measurement unit (IMU) that has 16-bit accelerometer and 16-bit gyroscope for quality output at a great price.This sensor comes with two sensors combined inside: an accelerometer (https://en.wikipedia.org/wiki/Accelerometer) and a gyroscope (https://en.wikipedia.org/wiki/Gyroscope) - both MEMS sensors (https://en.wikipedia.org/wiki/MEMS). Bosch has a ton of experience with making MEMS sensors - one of our very favorite sensors is the Bosch BNO055 (https://www.digikey.com/en/products/detail/bosch-sensortec/BNO055/6136301) which has accelerometer, gyro and also magnetometer as well as a SAMD21 chip inside that runs a sensor fusion algorithm, which makes it great for projects that want to get going with full orientation data quickly. But you'll pay for that convenience: the BNO055 costs about $7.50 a hefty BOM cost.If you've already got a microcontroller on your design, say a Cortex M series or ESP32 or other fairly powerful chip with an FPU or secondary core, you can save a bundle by DIY'ing your own sensor fusion. You can even do some very basic orientation sensing with just a 6-axis sensor like this one, or if you want to also fuse in magnetometer data, the BMM150 (https://www.digikey.com/en/products/detail/bosch-sensortec/BMM150/4196671) is a great mini I2C sensor that will work with any Bosch 6-axis IMU - combine with the BMI323 and for about $3 total you can have great 9-DoF sensor. Then you can use Bosch's Sensor Fusion Software (https://www.bosch-sensortec.com/software-tools/software/sensor-fusion-software/) BSXlite which comes as binary blobs for ARM Cortex chips that take in the raw sensor values and pop out quaternion (https://en.wikipedia.org/wiki/Quaternion) and Euler angles (https://en.wikipedia.org/wiki/Euler_angles) - you could probably request for them to compile it for another chip family like Tensilica or RISC-V if you like. The BMI323 has 16-bit data out for both sensors, and FIFO's so you will get quality data without skipping a sample.There's a full datasheet that goes through every setting and register for the BMI323 but if you'd like to skip the low-level implementation part, Bosch has been great for releasing portable C code support for their chips and the BMI3 series has its own github repo (https://github.com/BoschSensortec/BMI323-Sensor-API) with just about all functionality implemented. Note it's fairly 'generic' code, with Linux Kernel headers but otherwise without HAL implementation, so you'll need to port the common.c file to your platform (https://github.com/boschsensortec/BMI323-Sensor-API/tree/main/examples/common) to read and write I2C or SPI and add chip-specific delay.If the idea of a low cost IMU has you doing the twist or shaking your arms in excitement, the Bosch Sensortec BMI323 Inertial Measurement Unit (https://www.digikey.com/short/m33tnfdn) is in stock now at Digi-Key, with thousands of pieces ready for instant purchase. Order today and Digi-Key will package and ship your shipment instantly: you'll be motion sensing #LikeABosch (https://www.bosch.com/stories/like-a-bosch/) by tomorrow afternoon.

Released by Lakeside in 1979, was a ground-breaking electronic game of its time that was touted as "the ultimate playmate". The game, housed in a transparent blue dome, was activated by lifting the dome, revealing four games and three skill levels to choose from.The four games offered unique challenges to players:1️⃣ Countdown: This one-player scenario tasked players with lighting all 10 lights in the correct order in the fewest number of moves.2️⃣ Black Hole: Another one-player game, Black Hole had the same objective as Countdown but with an added twist—if you pressed an already lit button, the game would turn off all the lights ahead of it and the light itself.3️⃣ Brain Battle: A two-player game, one player had to turn off all the lights starting with number one, while the other player had to turn all the lights on, starting with number six.4️⃣ Light Race: This two-player game was a race to turn on more than five lights.Computer Perfection was not just a game; it was a sign of the times. In the late 1970s, a number of toy companies began producing electronic games for a public fascinated with computers. These toys, Computer Perfection included, helped usher in a new era of more sophisticated electronic gameplay.Computer Perfection, gained considerable media attention for its cameo in the second season of "Buck Rogers in the 25th Century" (1979-1981). In the episode "Mark of the Saurian," viewers can notice Computer Perfection's distinct blue dome beside Buck's (Gil Gerard) bed in the Searcher sick bay. 🎮📺🚀🛏️💙#ComputerPerfection #RetroGaming #LakesideVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

We've often made little robots or games and we need a quick and small gamepad-like interface to control motors or robots or whatever. this gamepad will do nicely: it has an analog thumb-stick, and six buttons: A B X Y and select start. the two analog readings and six digital readings are managed by an onboard seesaw peripheral https://github.com/adafruit/Adafruit_seesawPeripheral attiny816 - so once the PCBs are assembled we gotta program that chip. we made a programming shield with a metro m0 https://www.adafruit.com/product/3505 and OLED screen. we use an M0 because we need a fair amount of memory to store the firmware of the target board in flash, plus solid hardware serial support to perform the UPDI program. the screen lets you know when its time to test the buttons by pressing them, in a few seconds we're done!#Gamepad #Robots #AdafruitVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
count em: one, two, three...four rotary encoders encrust this new Stemma QT board! with a lil attiny817 running the adafruit seesaw code, we can now read 4 encoders and 4 switches plus control 4 matching neopixels all over I2C. great for when you do not want to spend all your microcontroller cycles counting out all your interrupted pins plus also clocking out neopixels. we don't have a ton of room on this 'standard sized' 4 inch by 1 inch PCB, so we stuck the pixels underneath. now on low cost encoders you can't really see the lighting, but on fancy 'clear body' encoders you can get a cool glowing effect! there's even clear or translucent knobs one can get that will diffuse the color nicely.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #rotary #encoder
We picked up a Gravis Advanced (https://www.mocagh.org/loadpage.php?getgame=gravis-front) PC analog joystick to verify our design for an adapter board is all peachy-keen. after some confusion about the way buttons work - turns out you DON'T want the knobs on the side centered because that disconnects the switches from the DE-15 - we have some success! since the X and Y positions are changed by the joystick moving the wiper on two pots (https://allpinouts.org/pinouts/connectors/input_device/joystick-pc-gameport/) and not by a voltage divider, we have to do a tiny bit of math to figure out the actual resistance. so far this board works very nicely and will let some of those old joysticks live again in modern projects. here we have a QT Py reading the values, and it would be trivial to convert this to a USB HID keyboard, mouse or joystick interface.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #gravis #retro
The chip shortage may be winding down, but there are still a few parts that didn't make it to the other side. To wit: the TCS34725 color sensor, a mainstay in so many Adafruit projects (https://learn.adafruit.com/products/1334/guides) has been discontinued (https://www.digikey.com/en/products/detail/ams-osram-usa-inc/TCS34725FN/3737685). We loved this sensor as it had a few nice things going for it: Red/Green/Blue and Clear diode sensors, IR blocking/cut filter, INTerrupt output, I2C communication, and a low cost of under $2 in quantity. We may not be able to get the exact same sensor, but let's try to find something with as much overlap as possible.See the chosen part on Digi-Key at https://www.digikey.com/short/5mphn0bjVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/

we never had a PC when we were younger so we sorta missed out on having a PC joystick - but this Gravis Advanced (https://www.mocagh.org/loadpage.php?getgame=gravis-front) design was rugged enough to survive 30 years - there's a datecode of 1991 on the PCB. PC joysticks are fairly simple: there's three mechanical buttons but actually you can only map them to 2 possible pins - the mapping is done with these rotary switches which confused us at first but turns out they have contacts that switch around which pads go from the onboard PCB to the DE15. the X and Y positions are changed by the joystick moving the wiper on two pots (https://allpinouts.org/pinouts/connectors/input_device/joystick-pc-gameport/). note they aren't connected up as a resistor divider - that's because there were no ADC's on PCs at the time - instead the resistance was fed into an oscillator like the 555 and then the pulse width measured!

We'll be stocking this ANO rotary encoder breakout in the shop soon, it lets one quickly connect and read the buttons and encoder on an 'ipod classic' over I2C. we like to make a good visible demo that is shown on a product page that really gives folks a good idea of how the product works, so here we've got it hooked up to an I2C 7-segment backpack (https://www.adafruit.com/product/878) with a touch of Arduino code to display the counter ticks from the encoder moving back and forth, and some text for when each of the 5 buttons is pressed.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #ipod #ano

The prop-maker feather has so much hardware built-in, its going to be great for making props and toys that have audio, motion and LEDs. we whipped up a quick demo that shows off LED animations (https://github.com/adafruit/Adafruit_CircuitPython_LED_Animation) on neopixels, motion sensing with the LIS3DH (https://www.adafruit.com/product/2809), servo output control to a micro servo (https://www.adafruit.com/product/169), and audio playback via a 3W I2S amplifier (https://www.adafruit.com/product/3006). CircuitPython has great I2S audio playback support and even supports digital mixing so there's volume control with an external potentiometer. All of this is running concurrently with excellent resposiveness, so we're going to order the PCBs shortly.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
bee bap boo bap bap, we're testing out our I2S BFF that we designed a few months ago (https://blog.adafruit.com/2023/01/28/a-new-bff-with-i2s-audio-amplifier/) - makes adding high quality audio really easy for many microcontroller boards like the RP2040 or ESP32 QT Py's. Here I'm running an MP3 streaming demo (https://github.com/schreibfaul1/ESP32-audioI2S) on an ESP32 QT Py and it's working great to play Frequency by BartleBeats direct from Bandcamp (https://bartlebeats.bandcamp.com/album/frequency)! Of course it also works great with playing from onboard flash or micro SD cards, particularly in CircuitPython where we have concurrent I2S audio playback baked in.

We have done 300 revisions (https://blog.adafruit.com/2023/04/27/300/), including just-about-all of our OLED, E-Ink and TFT displays to add EYE SPI connectors (https://www.adafruit.com/search?q=eye+spi) to make it very fast and easy to wire up displays, touchscreens and microSD cards without a ton of breadboarding. yay! but now we have to make the controller side easy as well. First up, this EYE SPI accessory for the QT Py uses a slim FPC connector (https://blog.adafruit.com/2023/04/04/the-great-search-narrow-body-fpc-connector-with-18-pins-and-0-5mm-pitch-thegreatsearch-digikey-digikey-adafruit/) and makes plug-n-play connectivity to our 2.8" capacitive touch screen child's-play (https://www.adafruit.com/product/2090). works a treat - we'll be getting this into the adafruit shop faster than you can blink.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI will drive it's way into your heart and into your motorized design BOMs: it's the Texas Instruments DRV8411 Dual H-Bridge Motor Driver (https://www.digikey.com/en/product-highlight/t/texas-instruments/drv8411-dual-h-bridge-motor-driver), a nifty multi-purpose dual H-bridge driver for use with either two brushless DC motors or bi-polar stepper motor. This driver features a wide operating voltage, from 11V down to 1.65V, and up to 4A current output so it can be used in just about any motor control design. It's intended as an upgrade replacement to the popular DRV8833 (https://www.digikey.com/en/products/detail/texas-instruments/DRV8833PW/4251165), with pin-compatible options or with reduced BOM options if you're good with a little redesigning.Now you might be thinking: Hey, that DRV8833 (https://www.digikey.com/en/products/detail/texas-instruments/DRV8833PW/4251165) part number sounds so familiar - where have a I seen that before? Well, if you were thinking that you saw our Chip Shortage video clip from about 1 year ago (https://blog.adafruit.com/2022/05/26/chip-shortage-ti-drv8833-motor-driver-chipshortage-adafruit-adafruit-digikey-txinstruments/) we were desperately begging for some DRV8833's in PWP package so that we could get Crickit boards back in stock (https://www.adafruit.com/product/3093). We did get some eventually so that we have both our Crickit and DRV8833 breakout boards (https://www.digikey.com/en/products/detail/adafruit-industries-llc/3297/6419360) back in stock but now we're looking at maybe updating the design with this fancy upgrade.The original DRV8833 is a great chip, and can drive two DC motors or one stepper at 2.7-10.8V and peak current of 2A. To compare, the DRV8411 has a wider range of 1.65-11V which means its better at low voltage motors, say ones running off of 2 alkaline batteries. It's also available in 4A peak output transistor as the DRV8411A (https://www.digikey.com/en/products/detail/texas-instruments/DRV8411ARTER/18111300) - double the current!Note that if you are pushing that much current, at long intervals, through your driver you will have to think about heat-sinking (https://www.digikey.com/en/videos/c/cui/how-to-select-a-heat-sink). There's a section in the datasheet about how to use copper fill as a heat sink: 2 oz copper will do better than 1 oz and you'll want a large square area. Otherwise, you may have to look at adding an external heatsinking or forced cooling with a fan.Or, you may want to avoid getting into such a hot state by adding current limiting. These drivers can use a resistor that is in series with the motor power to limit how much current will sink: once the voltage across the resistor hits 200mV, the feedback system will reduce current draw. Our original breakout used these power/current-sense resistors to limit current to 1.2A by default.One nifty feature we saw in the DRV8411A version (https://www.digikey.com/short/5d917nh7) of this family is they've gotten rid of the 'in path' current sense resistors. While they worked great they needed to be high wattage in order to handle the full current from the motor path. The A changes this to a current mirror (https://en.wikipedia.org/wiki/Current_mirror) so that low wattage resistors, say 0402 or 0603 size, can be used instead saving a ton of space. You can also connect the monitor pads to your favorite microcontroller ADC to monitor current draw.And, oh yes, the DRV8411 (https://www.digikey.com/short/f8z23pm7) and DRV8411A (https://www.digikey.com/short/5d917nh7) are both in stock right now for instant shipping from Digi-Key! When you order from Digi-Key they will pack and ship your order from Thief River Falls within the day and you will get it as quickly as tomorrow morning so you can get your motors twisting and turning with this fabulous NPI.

A super fun chip to have in your toolkit is an analog switch or multiplexer (mux) - which can act like an SPST but doesn't require a mechanical switch. There's a few things to watch out for, but these are very handy when you want to move analog signals around. The Bus Pyrate design we were working on uses a 4066 in TSSOP - let's find a chip that we can use in this design but also poke around at some other analog switches and muxes that are available on Digi-Key!See the chosen part at Digi-Key at https://www.digikey.com/short/0zdpzrzn

This week's EYE ON NPI is like a beam of sunlight shining into your life - it's the Cree XP-G3 Photophyll™ Select LEDs (https://www.digikey.com/en/product-highlight/c/cree/xp-g3-photophyll-select-leds)! These are high-power illumination LEDs that are designed specifically for horticulture lighting.Before we begin - we do want to clarify that you don't have to worry about these LEDs being from the Kree-with-a-K (https://marvel.fandom.com/wiki/Kree) - the powerful blue-skinned and technically advanced humanoid race that antagonize the Marvel Cinematic Universe. No, these are from the technically advanced and very peaceful Cree corporation, who do not have blue skin but do make powerful blue LEDs (https://www.digikey.com/en/products/detail/creeled-inc/XPGDRY-L1-0000-00501/7134715). Cree-with-a-C is famous for their wide range of powerful LEDs that are available with precision binned frequencies (https://forum.digikey.com/t/cree-led-binning/761)To create an LED, we first need to create a diode (that's the D in LED) - with P-doped and N-doped silicon (https://en.wikipedia.org/wiki/Light-emitting_diode_physics) the two doping materials are specifically picked so that when current is passed through, photons are emitted that match a desired frequency (https://en.wikipedia.org/wiki/Light-emitting_diode_physics#Materials). Originally we only had Gallium-Arsenide which could make red light, then with tweaking we could move the frequency around to get yellow or light green. Then new materials were discovered to give green, blue light or even UV. You'll note on that Wikipedia article that the frequencies have a range - and depending on the doping techniques the frequency can shift around. Low cost LEDs just come in "Dim Red" or "Bright Green" and are not guaranteed to all match color and brightness - although they tend to be close.If you need perfect color and brightness matching you need to get binned LEDs: When manufactured, the LEDs are quickly tested in each batch to determine the exact frequency and then placed into a 'bin' labelled with that value. Whenever you buy that LED you're guaranteed to get ones that emit the same frequency - within some established error margin. You pay more but have fewer surprises - that's Cree's expertise (https://forum.digikey.com/t/cree-led-binning/761).For growing plants, of course it's easiest to just stick them under the sun which does a great job of providing the sunlight photons required to kick off photosynthesis. (https://en.wikipedia.org/wiki/Photosynthesis) But perhaps there's not enough light where you're at, or you need to have the plants indoors to protect them from weather, or they're seedlings and it isn't spring. That's where grow lights come in! (https://en.wikipedia.org/wiki/Grow_light) There's a ton of research into the science of what kind of lights work best for different plants (https://journals.ashs.org/hortsci/view/journals/hortsci/50/9/hortsci.50.issue-9.xml) - historically folks used fluorescent or halide lamps, but LEDs have the benefit of not dimming or burning out over time as long as they are heat-sinked - and even better you may not even need active cooling. Make sure to follow the Cree documentation on packaging and heat-sinking, and use aluminum-backed PCBs to help diffuse heat. (https://www.digikey.com/en/articles/led-heat-dissipation-and-lowering-thermal-resistance-of-led-lighting-substrates)If this spring has inspired you to dabble in a green thumb, or maybe you have a horticultural-science product you're developing, the Cree XP-G3 Photophyll Select LEDs (https://www.digikey.com/short/t07dnf4t) will be super efficient for any cyber-plant grow lighting system. And best of all, they're in stock right now at Digi-Key for immediate shipment, in a variety of binned ratios. Order today and you'll be glowing and growing by tomorrow afternoon.

This week's EYE ON NPI is just in time for Earth Day - it's a new environmental sensor: the ScioSense ENS160 Air Quality Sensor (https://www.digikey.com/en/product-highlight/s/sciosense/ens160-air-quality-sensor) - a digital multi-gas sensor that offers optimum detection of volatile organic compounds (VOCs) and oxidizing gases. This is a 4-in-one sensor that improves on common MOX gas sensors that have become popular on the market, but is still super easy to use.This sensor is the successor to the popular CCS811 (https://www.digikey.com/en/products/detail/sciosense/CCS811B-JOPD500/6569311), which we used for many years and was one of the first embedded MOX sensors on the market. It was quite popular but only had one MOX plate, and has been improved with the introduction of the ENS160.Gas sensors are all essentially resistive sensors, where the exposed silicon has a metal oxide layer (MOX) that is susceptible to ambient gasses. There's a heater element that you need to turn on, then wait until the silicon chunk can react with the air. The resistance changes with the amount of organic compounds in the air and you can measure the resistive differences. (https://en.wikipedia.org/wiki/Electrochemical_gas_sensor)Traditional gas sensors came with 4 pins: two for the heater, and two for the resistor. You have to power the heater, then use a resistor divider or op-amp to read the resistance and back calculate. (https://learn.adafruit.com/gas-sensor-comparison/connect-the-sensor-boards) There's no built-in calibration available, you'll have to figure out what each resistance 'means' in human-friendly terms like AQI or ppm/ppb concentrations. This made a lot of gas sensors difficult to use, and also unreliable without constant upkeep. (https://www.google.com/search?q=alcohol+sensor+calibration)The new generation of MOX gas sensors follow in the footsteps of humidity sensors that were originally just capacitive sensors, but now are fully integrated with instant usable data. The CCS811 was one of the first to do this, a real pioneer. For these types of sensors, the MOX element is hidden inside, and the heater is automatically or digitally controlled. Baseline readings are used to provide home or office-grade calibration where we may care more about changes in readings rather than absolute readings. For example, an office's eCO2 reading has increased over the day from "good" to "poor" - that would indicate a need to turn on an HVAC fan or alert someone to open a window.The ENS160 has 4 different sensor elements, each one will have slightly different MOX doping, which means it will react to different classes of gasses. Which is something to remember: it's not like you can tell which TVOC you're sensing - the whole family of ethanol, methane, acetone, etc. are all going to activate the sensing bodies. Likewise - if you need precision CO2 measurements, nothing beats an NDIR sensor (https://en.wikipedia.org/wiki/Nondispersive_infrared_sensor). But those sensors are also pretty expensive - and don't do TVOC sensing. For basic usage, eCO2 will work just as well and at significant power and cost savings. Likewise, if you need specific TVOC sensing, those will cost a lot more but they are tuned.What we like about the sensor is that it's fully integrated: no firmware blobs or NDAs required which means we were able to get it ported to Python without difficulty.(https://github.com/adafruit/Adafruit_CircuitPython_ENS160/blob/main/examples/ens160_advancedtest.py) There's also an Arduino library published by ScioSense for integration in any C/C++ build. The library supports temperature and humidity compensation as well.If you think the ScioSense ENS160 Air Quality Sensor (https://www.digikey.com/short/mcv97mq2) is a breath of fresh air, then you're in luck because they're in stock right now at Digi-Key for immediate shipment! You can also pick up some of the Adafruit-made breakouts for the ENS160 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/5606/16750376) to get you started fast - our breakout includes regulators and level shifting, so you can drive it from 3 or 5V power and logic. Order today and you'll have them in your hands by tomorrow afternoon.

our first version of the pico dvi bell didn't quite work, but the second version has the right pinouts and is ready for testing. here we're trying it with CircuitPython and WiFi support: so we're able to connect over the internet with SSL to a site, get data, and then display it on a monitor. since the Pico W requires a lot of memory for the wireless connectivity we're using monochrome DVI output which means we have about 50K remaining after the framebuffer is allocated for the DVI display.

This week's EYE ON NPI will stick by your side like a faithful hound- it's the BeagleBoard.org BeaglePlay® Single Board Computer (https://www.digikey.com/en/product-highlight/b/beagleboard/beagleplay). Single Board Computers (SBCs) are like tiny computers that are less powerful than desktops but much better at booting quickly and interfacing with hardware. They also tend to run Linux or BSD because it's easier to get those OS's ported to new chipsets than convincing Apple or Microsoft!This new generation of SBC from BeagleBoard builds on their prior success with the BeagleBoard (https://www.digikey.com/short/1cmb3dtf) and BeagleBone (https://www.digikey.com/short/c52dpz47) by adding a ton more interfaces and connectors so many projects can be built with no soldering. Here's a bullet list to get us started:AM6254 SoC processor16 GB eMMC storage2 GB DDR4 memorySupports expansion with OLDI, 4-lane CSI, and QWIIC connectorsCSI for compatibility with the BeagleBone AI-654, Raspberry Pi Zero W, and compute modulesFull-size HDMI connectorSmall size: 8 cm x 8 cmUSB Type-C® with 5 V @ 3 A input connectormikroBUS connectorRJ45 Ethernet connector for Gigabit EthernetWi-Fi 2.4 GHz and 5 GHz capabilitiesBLE and SubGMicroSD slotUSB Type-A connector at 480 MbitGrove connectorThe main processor is the TI Sitara AM6254 (https://www.digikey.com/short/507rmwr2) with quad-core 64-bit A53 and a Cortex M4 coprocessor. This chip is paired with 2 GB of DDR4 RAM and 16 GB of eMMC storage for a powerful AI-ready chipset that has tons of onboard graphics support such as 1080P HDMI and 4 lanes of OLDI/LVDS. This chip has 9x UARTS, 5x SPIs, 6x I2C's, 3x PWM modules, 3x quad encoders, and 3x CAN-FD, and of course some GPIO. Note there's no ADC or DAC - you'd use SPI to connect those externally.Note this board doesn't have a 2x20 header like a Raspberry Pi, or even the dual header strips from the BeagleBone - but in exchange it stuffs a ton of hardware support directly onto the PCB. For example, if you'd like to add a camera, there's an onboard 22-pin 0.5mm pitch CSI FPC connector that is compatible with the Pi Zero camera cables (https://www.adafruit.com/product/5211) - use that adapter to interface with any low cost Pi Camera modules or compatibles.For video output, a vertical full-sized HDMI port will connect to any monitor or display. In fact we plugged in our desktop monitor and powered the Play with a USB wall adapter, and it immediately came up with an X desktop display. Mouse and keyboard can be added via the USB 2.0 socket, a mini hub will allow multiple devices since there's only one type A port.The BeaglePlay does a great job of including everything you may want to expand your Raspberry Pi with. For example, there's a BQ32002 Real Time Clock (https://www.digikey.com/short/p0h10jbq) with a CR1220 coin cell holder right on board - normally that would have to be included as a separate module. A microSD card slot can be used for storing large amounts of data: unlike most SBCs, there's onboard 16GB eMMC so you don't have to juggle SD cards to install the OS.There's also a ton of expansion ports! For I2C, the onboard QWICC (https://www.sparkfun.com/qwiic) JST SH connector lets you use the hundreds of SparkFun sensors as well as any Adafruit Stemma QT (https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma) devices. For UART/PWM/ADC/I2C/GPIO you can use the onboard Grove connector.Finally, for networking either to the Internet or to a sensor network, there's Gigabit Ethernet, WiFi 2.4G and 5G, BLE and Sub-G networking. Yeah that's a lot! It's almost all provided by the onboard TI SimpleLink CC1352P7 (https://www.ti.com/product/CC1352P7) which boasts support for 6LoWPAN, Amazon Sidewalk, Bluetooth 5.2 Low Energy, IEEE 802.15.4, MIOTY, Proprietary 2.4 GHz, Thread, Wi-SUN NWP, Wireless M-Bus (T, S, C, N mode), Zigbee. Note LoRa is not in there, so if you need LoRa that would be added with a separate module. There's also an RJ-11 with Single-Pair Ethernet (https://blog.adafruit.com/2020/08/27/eye-on-npi-harting-single-pair-ethernet-eyeonnpi-digikey-ethernet-digikey-harting-adafruit/) which makes this a good fit to connect to industrial robotics or automation.All this hardware is available at a great price of under $100 at Digi-Key, we already picked one up and we're going to try and get Blinka working on it (https://github.com/adafruit/Adafruit_Blinka) so that all of our CircuitPython libraries will 'just run' in CPython. Especially given the ready-to-run Stemma QT / Qwiic port on the side, this is an excellent board for a powerful but solder-free configurable SBC. Digi-Key has tons of BeaglePlay's stock for immediate shipment, so order today (https://www.digikey.com/short/jpztmq3w) and you will be playing with your new BeaglePlay by tomorrow afternoon.

This weekend we took an itsy-bitsy-tiny-winy break from churning out new designs to try and dig our way out of the giant sample pile! we've got cool rotary encoders, some I2C LCDs, conductive fabrics, a miniature USB camera and more. Also, we'll snoop around tannewt's github repo to find a build of the DVI Feather for CircuitPython that now supports displayio to an HDMI monitor.The Great Search - Character LCD Display with I2Chttps://www.digikey.com/short/wd43mnwdThis week in our sample pile we have an I2C/SPI character LCD module we're checking out. Although historically 16x2 character displays use a parallel method of addressing - with 4 or 8 bit data input and a write latch - most folks don't want to waste so many pins on such a slow display. So, instead, many now come with I2C interfaces. That makes wiring or routing a lot easier!

This week's EYE ON NPI is an EYE in the SKY, as we're featuring our first NPI from Skyworks: the Skyworks Si3404 and Si3406x Power over Ethernet [PoE] Powered Device Chips (https://www.digikey.com/en/product-highlight/s/silicon-laboratories/si3404-and-si3406x-power-over-ethernet-powered-device-chips). PoE is a standard, supported by many Ethernet hubs and switches (https://www.tp-link.com/us/solution/poe/) that allows a device connected to the hub to request +48V power over some of the Ethernet lines in Cat-5 cabling. Since many devices need Ethernet for speed and reliability - cameras, phone systems, printers, standalone monitors, and door entry systems, for example - you only need a single cable. These chips, originally from Silicon Labs and now made and sold by Skyworks, allow product designers to quickly add PoE support to their Ethernet products, saving space, complexity and wiring because a separate power supply is no longer needed.eFirst up, if you're wondering: "wow Skyworks, where have I seen that name before?" That's right! It was the California fabrication facility (https://en.wikipedia.org/wiki/Such_Great_Heights#Music_video) where The Postal Service's Such Great Heights video was shot (https://www.youtube.com/watch?v=0wrsZog8qXg). The original video even featured the Skyworks logos on the chips - now it's blurred out. But that's a great excuse for us to mention that there's a Postal Service/Death Cab 20th Anniversary Tour this fall and we are definitely getting tickets (https://giveuptransatlanticismtour.com/).But back to PoE chips! We watched a discussion video (https://www.youtube.com/watch?v=tEhbVpYFvk0) about the history of this chip line, we were struck by the observation that the reason PoE is so popular for office buildings is that it's very disruptive and expensive to get electricians to run power outlets everywhere. But running Ethernet can be done by the IT department because the voltages are so low that no special licensing or permitting is needed. Ethernet can be run behind drywall, around door frames, or under drop floors without worrying about electrocution or fire hazards. And you don't have to worry about DC plug adapters or voltage mismatches.The Si3404 can provide up to 13W (https://www.digikey.com/short/49dqqh9m), the Si3406 can do 25W (https://www.digikey.com/short/35jn99tc) but are otherwise very similar. Other than a few passives and full-wave bridge rectifiers, you only need the flyback inductor-transformer (https://www.digikey.com/en/products/filter/switching-converter-smps-transformers/168) - for isolated setups, it's a little more complicated. The Si3404 can also perform as a non-isolated buck converter for very small and low cost designs. The output voltage is set by a simple feedback resistor divider. Designs are compact, less than 1 square inch, for most use cases.Both the Skyworks Si3404 (https://www.digikey.com/short/49dqqh9m) and Si3406 (https://www.digikey.com/short/35jn99tc) are in stock right now at Digi-Key for immediate shipment. There are also eval boards (https://www.digikey.com/en/product-highlight/s/silicon-laboratories/si3404-and-si3406x-power-over-ethernet-powered-device-chips) that come with buck/flyback/isolated setups so you can test them as replacements for your current power supply to make sure which schematic you'll follow. Order them today for immediate delivery - through the Postal Service or whatever your favorite carrier may be - and you'll be making your IoT designs easy-to-power by tomorrow afternoon!

This weekend we whipped up a quick FUSB302 (https://www.digikey.com/en/products/detail/onsemi/FUSB302MPX/5844455) breakout that will allow USB Type C sink power negotiation. Basically, we can plug into a USB hub or wall wart that can provide up to 20V and request that much voltage. This could be really handy for audio or robotics projects that need 9V, 12V, 15V or 20V without the fuss of finding a matching DC adapter.Now that we've got the chip, the datasheet lets us know that we need a separate, external 3.3V-ish regulator to supply power to the chip. Let's go looking for an LDO that can handle 5V-20V in, and provide 3.3V and at least 100mA, along the way we'll also check that we have voltage-rated components and also chat about LDO versus buck converters for this use case.See the chosen chip on Digi-Key at https://www.digikey.com/short/j3jtz4zm

This week's EYE ON NPI will have you tripping all over yourself in a rush to place a Digi-Key order for the Tripp Lite Antimicrobial Surge Protectors (https://www.digikey.com/en/product-highlight/t/tripp-lite/antimicrobial-surge-protectors-for-home-and-office) a range of power extenders that have tons of ports for your home or office workstation. We're used to basic '6 outlet' power extenders, so when we peeped the many funky shapes, we picked up a few for the home office. Here's our favorites of the series:The TLP648UCBAM (https://www.digikey.com/en/products/detail/tripp-lite/TLP648UCBAM/16161493) has a U-shaped body that is designed to clip onto a desk. Note it doesn't clamp down so you'll want to put it to the side where it can't get bumped, and a thick desk - like 1" or more - will probably work best. This one has 6 outlets, three on each side, two USB A 5V 2.4A and one USB C 5V 3.0A plug for portable devices. This is great for a work bench where you may have a few computers, scope, power plugs, and then also you want to charge your phone or power a single board linux computer or dev kit.The TLP68UBAM (https://www.digikey.com/en/products/detail/tripp-lite/TLP68UBAM/16161654) is kinda like those yachts that have another, smaller, boat that can launch off of it (https://www.travelpulse.com/News/Entertainment/This-Yacht-Has-a-Garage-for-Your-Boat). There's the main power outlet plate with 6 outlets, then a detachable clamping USB power module that extends out and clamps onto a desk for plugging in up to 4 USB Type A. This one is nice if you're OK with having the power adapter on the floor or otherwise hidden behind your workspaceThere's also some super funky shapes, like the cubic TLP368CUBEUAM (https://www.digikey.com/en/products/detail/tripp-lite/TLP368CUBEUAM/16161497) which is evocative of a Borg Spaceship (https://memory-alpha.fandom.com/wiki/Borg_cube) Or the spherical TLP38UAM (https://www.digikey.com/en/products/detail/tripp-lite/TLP38UAM/16161623) with 3 outlets and 4 USB ports. While we didn't pick up a TLP410UCUFOAM (https://www.digikey.com/en/products/detail/tripp-lite/TLP410UCUFOAM/16161616) we do note how useful it would be for a conference table so that folks don't end up crouching below the table then bonking their heads.But our number one fav, which we're going to use on the desk we broadcast EYE ON NPI from, is the TLP608DMUAM (https://www.digikey.com/en/products/detail/tripp-lite/TLP608DMUAM/15298401) - a cute twist on the familiar 6-outlet favorite. First it is extra long so there's the 4 compact-outlets and then two chonky outlets for big power adapters. There's also two USB A ports with 5V 2.4A out max. Unlike the first adapter we showed off, this one has two thumbscrew clamps that can attach in any direction to any thickness desk. We're going to use this on our Ask-an-Engineer desk to power the lights, overhead cameras and demo boards that power over USB.A power outlet is kinda like a pair of shoes, belt or toothbrush: you want to get really good quality ones because you use them all day every day. The Tripp Lite series from Eaton (https://www.digikey.com/en/product-highlight/t/tripp-lite/antimicrobial-surge-protectors-for-home-and-office) are high quality, surge protected, and are a huge improvement from what you'd normally pick up for $20 from the hardware store. And Digi-Key has all of them in stock for immediate shipment! Order today and you can neaten up your desk wiring by tomorrow afternoon.

While doing a teardown of a toy cactus that mimics people (https://www.google.com/search?q=mimic+cactus) by recording & replaying the last few seconds of audio, we were reminded of ISD audio chips. These record-and-playback chips have been around for decades and are a favorite with makers and engineers who want to quickly add audio prompt playback without big processing capability. These chips don't require battery backup or a flash memory chip, they keep the audio clips stored internally in a compressed format. Originally these were popularized in use cases like "digital greeting cards" that you could record a message onto. Despite being quite old, they're still used a lot and are very simple and often available in large packages, so for many projects they're still the easiest way to do add simple sound effects or audio messages. Digi-Key has a wide range of ISD audio chips available for purchase, let's look at the large range and pick a good one to start with.See the chosen chip on Digi-Key at https://www.digikey.com/short/pbjf0zrh

This week's EYE ON NPI is your best buddy for broadband, it's Nordic Semiconductor's NRF7002 Companion IC (https://www.digikey.com/en/product-highlight/n/nordic-semi/nrf7002-companion-ic), a wireless add-on chipset designed for the Nordic Semi nRF52 (https://www.digikey.com/en/products/filter/rf-transceiver-ics/879?s=N4IgTCBcDaIHIHsBOATAlgYwAQGUCmAtmlgHYBKAYgKwQC6AvkA) and nRF53 (https://www.digikey.com/en/products/filter/rf-transceiver-ics/879?s=N4IgTCBcDaIHYHsBOATAlgYwARyQMwFYBmEAXQF8g) ARM+Bluetooth and nRF91 ARM+Cellular (https://www.digikey.com/en/products/filter/rf-transceiver-ics/879?s=N4IgTCBcDaIHIHsBOATAlgYwAQGUCmAtmlgHYBKAYgJwCMIAugL5A) to act as a WiFi peripheral. With the addition of the nRF7 series, Nordic now covers the three most popular wireless transports: Bluetooth LE, LTE Cellular, and WiFi! This is a pretty big deal, because it's their first foray into WiFi technology, so we expect that there will be more integration in the future.The nRF7002 is a standalone chip, which requires only a few passives and an antenna, that performs the low-level interfacing to communicate with WiFi networks. Data is transferred back and forth between the nRF7 and host processor using SPI or QSPI - for higher speeds!. At this time, it seems like the driver is only available via the Nordic SDK and using Zephyr RTOS (https://github.com/nrfconnect/sdk-nrf/tree/main/drivers/wifi/nrf700x) - both of which would be good options because the WiFi stack lives on the host chip which means an SSL implementation which can require significant RAM and Flash. You'll also need to store the chip patch firmware blob and transfer it over SPI on boot - again requiring storage or flash memory.So why use this chip instead of an integrated WiFi core? Well, one thing is you may want to connect to 5GHz networks (https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_(802.11a/h/j/n/ac/ax)), which the nRF7002 supports in addition to 2.4GHz, and you may need a processor with specific peripherals or quantity of GPIO or speed, or you're already using the nRF53 or nRF91 chipset - that's when the nRF7002 is going to shine. Nordic is also known for really good and complete SDK's for nicely documented and supported peripherals with excellent low-power numbers.For a fast start, grab the NRF7002-DK eval board (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF7002-DK/17748188) that you can pick up with has an nRF53, JLink interface, antenna ports, and other accessories for quick bringup of a dual-BLE-WiFi design. It's still pretty early, but we can expect to see tinned modules come out into the market soon, for example Fanstel products are stocked at Digi-Key (https://www.digikey.com/en/products/filter/rf-transceiver-modules-and-modems/872?s=N4IgTCBcDaIGYEMB2BnALgUwDYgLoF8g) and it looks like they're working on a few nRF7002 options (https://www.fanstel.com/nrf7002wifi6module).For software, it's also pretty early since this is a new chip, but there's lots of examples in the nRF SDK (https://github.com/nrfconnect/sdk-nrf/tree/main/drivers/wifi/nrf700x) and also example code on the Nordic developer blog for MQTT connection (https://github.com/AliNordic/mqtt_over_wifi_nrf7002DK) and friend-of-the-fruit Golioth has a quickstart on how to use the nRF7002 to connect to their cloud for pub-sub and RPC currying. (https://forum.golioth.io/t/nordics-brand-new-nrf7002-wi-fi-chip-already-works-with-golioth/166). You can also use Nordic's free apps for provisioning over BLE or Cellular (https://www.nordicsemi.com/products/development%20tools/nrf%20wi-fi%20provisioner)If you want to add the nRF7002 to your design, now's the time to check it out because Digi-Key has lots of the Nordic nRF7002 in stock (https://www.digikey.com/short/48b0317m) right now for immediate shipment! Order today to get full WiFi 6 support into your next core design by tomorrow afternoon, with a powerful front-end chip that supports dual bands and antenna co-existence.

On last week's The Great Search (https://youtu.be/cB32kaMpqI0), we wanted to find a way to connect a whip-style antenna to our 915 MHz ISM Band Feather boards with either RFM69 or LoRa modules. We started by finding uFL to SMA adapter cables, with great success. Now we get onto the antenna part! to do range testing, lets get some nice big 915 MHz antennas with SMA connectors and with tiltable angle so that we can send and receive data from miles away! Digi-Key stocks thousands of antennas, but we can narrow down our search to one that fits our requirements, while also learning about gain and VSWR ratings.See the chosen part on Digi-Key at https://www.digikey.com/short/0d3rhz0fVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #thegreatsearch #digikey @Digi-Key #deskofladyada

these are two RP2040 'bones' boards that have an RFM69 900MHz module soldered in the empty spot, good for making basic wireless networks that have support for addressing and packeted data transmission. they can be transmitters or receivers, here both have the same code on them and when we press the user button on one feather, the opposite ones displays a message on the OLED with the RSSI. this makes it easy for me to verify the antenna quality. theres also a uFL antenna spot so we can connect big antennas using a uFL to SMA adapter - we covered finding these adapters on the Great Search this week! next up we will try RFM9x LoRa modules, those can run a LoRaWAN stack on the roomy RP2040 chip.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#radio #adafruit #lorazalora
We just wired up this EPD (eInk / ePaper Display) Feather and it works great! it's our "RP2040 Bones" board with standard 24-pin FPC eInk connector and support circuitry in the empty spot. with the 8 GPIO we've wired up a separate SPI port, 4 control pins, and then set up the NeoPixel to have a separate power pin so it will work better for low power usage. to be clear, the RP2040 isn't really designed for super low power usage, but every lil bit counts! we're going to send some over to tannewt next, so he can maybe test out the 7-color ACeP displays that were recently added to circuitpython and make sure they work with the component selection :)Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #eink #epaper
Twentieth Anniversary Macintosh - Limited-edition Apple computer (1997)The Twentieth Anniversary Macintosh (or "TAM") is a limited-edition personal computer released in 1997 to mark Apple's 20th birthday. The TAM was announced almost 20 years to the day after Jobs and Wozniak incorporated the company.The TAM featured a 250 MHz PowerPC 603ev processor and 12.1" active matrix LCD powered by an ATI 3D Rage II video chipset with 2 MB of VRAM capable of displaying up to 16-bit color at either 800x600 or 640x480 pixels. It had a vertically mounted 4x SCSI CD-ROM and an Apple floppy SuperDrive, a 2 GB ATA hard drive, a TV/FM tuner, an S-Video input card, and a custom-made Bose sound system including two "Jewel" speakers and a subwoofer built into the externally located power supply "base unit".A thick "umbilical" cable connects the base unit to the head unit, supplying both power, and communications for the subwoofer. This one was a lot of fun to photo, put together, and check out the video - rare footage!https://en.wikipedia.org/wiki/Twentieth_Anniversary_Macintoshhttps://support.apple.com/kb/SP408?locale=en_US#Marchintosh #apple #history

📸 Apple's QuickTake 150 (1995 - QuickTake 150 kit with case, cable, booster pack, and close-up lens accessories. Apple improved the file compression technology and released the QuickTake 150 in April 1995, replacing the 100. The 150 uses the same hardware as the 100, and the improved compression enabled the QuickTake 150 to capture 16 best-quality or 32 standard-quality images, with either quality level now stored at the full resolution of 640×480 in the 1MB of built-in storage.At the same time, Kodak introduced its DC40, which used a similar design and hardware as the QuickTake 150, but captured images at an increased resolution to a larger internal storage. The QuickTake 150 sensor was the same as used in the DC40, but masked to a lower resolution; the DC40 used the entire sensor instead.The QuickTake 150 kit also included PhotoFlash software (for Macintosh) or PhotoNow! (for Windows) and a separate close-up lens that changed the focus range to 10 to 14 inches (25 to 36 cm) and diffused the flash appropriately. Apple also offered several different accessories for the QuickTake 150, including a travel case, AC adapter, battery booster pack (using 8×AA batteries), and a connection kit for Microsoft Windows.https://en.wikipedia.org/wiki/Apple_QuickTake#QuickTake_150#marchintosh #apple #photography Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI is a DIN rail accessory that is great looking -- not to be confused with the Mandalorian Din Djarin (https://starwars.fandom.com/wiki/Din_Djarin) -- it's CUI Devices DIN Rail Terminal Block Connectors! (https://www.digikey.com/en/product-highlight/c/cui-devices/din-rail-terminal-block-connectors) They're a stackable set of feed-through or ground-type termination blocks that are slim and easy to snap onto any standard DIN rail for making quick up-to-4-contact distributions or connections to the grounding rail.DIN rails (https://en.wikipedia.org/wiki/DIN_rail) are a standardized mounting rail that is popular in electrical, server and industrial situations. By having one size rail that everyone agrees on, it's easy to snap-mount on any equipment that needs to be wall or cabinet mounted, without having to drill holes in walls or use 2x4 wood strips that are not rated for weight bearing. DIN rails are inexpensive, available in steel or aluminum, and pre-cut to any length you need - Digi-Key has tons in stock (https://www.digikey.com/en/products/filter/din-rail-channel/580) There are slots for easy mounting to cabinets or walls, that part isn't standardized, so check the specs for the railing you're ordering to make sure it's easy to mount. However, once that's done, you can snap various DIN rail holders and accessories (https://www.digikey.com/en/products/result?s=N4IgTCBcDaICYEsB2ACATgQwQGxAXQF8g) on very easily.Back to the topic at hand - CUI makes a variety of DIN Rail Terminal Blocks (https://www.digikey.com/short/2rdpm8n0) that snap into a standard rail, each slim device is a single terminal distribution for one contact. They are available in a few different sizes, for example the TBDR-12-25 (https://www.digikey.com/en/products/detail/cui-devices/TBDR-12-25-BK/17628393) is 46mm x 68mm and can handle 26 to 12 AWG. The TBDR-06-15 (https://www.digikey.com/en/products/detail/cui-devices/TBDR-06-15-GY/17628401) on the other hand is 30 mm x 48mm and goes down to 14 AWG at the max thickness, and the TBDR-08-25 (https://www.digikey.com/en/products/detail/cui-devices/TBDR-08-25-GY/17628397) is 35mm x 68mm. Basically, there's a wide range of sizes and configuration that you can mix and match to stack up your customized enclosure needs.These are designed to be able to handle high currents and voltages for power distribution, with CE and UL markings and support for up to 500V and 22A, but of course will also do nicely for data transfer or motor control. They're ideal for your next project where tidy and clean wiring is required.There are 18 different sizes/colors of the CUI DIN Rail Terminal Blocks (https://www.digikey.com/en/product-highlight/c/cui-devices/din-rail-terminal-block-connectors) available and all are in stock at Digi-Key right now. Don't forget to also pick up some of the 8 different 'end cap' pieces you can use to protect the last block in a stack. Since we have to feature one product in particular, we'll go with the TBDR-12-25-BK (https://www.digikey.com/short/2rdpm8n0) - all are great but we dig the bi-layer black look of this terminal block - it's also available in gray (https://www.digikey.com/short/vcz3v2r4) but whatever ones you pick, they'll ship instantly from Digi-Key and you'll have them in your hands as early as tomorrow afternoon!

We continue our quest to Pico-ify all our testers, moving away from Teensy 3.6 (they're unavailable) or Raspberry Pi's (good but have the overhead and brittleness of a full Linux computer). This time we're doing the 5303 ESP32-S2 Feather with BME280 (https://www.adafruit.com/product/5303) which can run through the full program and test in about 20 seconds. It's going to be slow and steady as we redo them all, but it feels great to invest in our test suite and make it easier and faster for our team to get these boards up and running! The tester brains board is on github here (https://github.com/adafruit/RP2040-Based-Tester-Brains-PCB) and the RP2040 code that does the ESP32's programming is here (https://github.com/adafruit/Adafruit_TestBed)Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #testing #raspberrypi
Our first Feather 'bones' board prototype is ready for testing! This is RP2040 with 8MB Flash, QT, USB C, Lipoly and the standard Feather pinout ... and at the other end a DVI connector that will work with any HDMI monitor or 'sink'! We tested that we can detect and read the sink's EDID EEPROM, the HPD (hot-plug detect) pin goes high when connected, and that we can generate both 640x480 and 800x480. Those are generated in the PicoDVI Arduino library (https://github.com/adafruit/PicoDVI) we have as pixel-doubled 320x240 or 400x240 so we have a full framebuffer in RAM that we can instantly display on output. It's basically like having an Adafruit GFX display but instead of to an OLED or TFT its a full color HDMI monitor! Kudos to PaintYourDragon for the wrangling, this works beautifully and easily with automatic overclocking.

This week's EYE ON NPI has 100% on Rotten Tomatoes, it's the latest installment of the Wick franchise - and dontchaknowit - this movie is all about making rework fast and easy with the Menda/EasyBraid WickGun Dispenser (https://www.digikey.com/en/product-highlight/e/easy-braid/wickgun-dispenser), which will let you dispense de-soldering braid with the same ease and skill that our famous assassin dispenses with the bad guys! (https://www.youtube.com/watch?v=xSM_nz6gKOI) Solder wick is awesome for reworking any printed circuit boards. It's made of fine copper braid that often has flux embedded in it, and it 'wicks' up solder cleanly and easily. It's great for SMT, especially bridging on chips pins, and also is helpful for cleaning up through hole parts.Digi-Key has some great tutorials on soldering, including this one that covers fluxing, rework, wick and headers (https://www.youtube.com/watch?v=DJH7VLGJ4fs), one from Becky Stern with lots of wire-soldering details (https://www.youtube.com/watch?v=sS4v2hIFp9I) and a video from Shawn Hymel (https://www.youtube.com/watch?v=X3Rc1s6EpSI) on QFN soldering and rework with hot air. Soldering is a bit of a messy process, especially for beginners, and it's easy to make mistakes where there's too much solder. That's where reworking techniques come in! It's dangerous to operate electronics with short circuits, as somehow it always turns out that the short is connecting some high voltage pin to a sensitive input.For through hole components, we always like to start off with a de-soldering pump, also known as a "solder sucker" (https://www.digikey.com/short/bvrwtzjv). Pumps are great for removing large quantities of solder, but are a 'big hammer' - they're not good for delicate tasks and also because they use the internal suction to pull solder away from the PCB, they're not good for removing the last solder from a through hole pad where the component has been removed because air just flows around the solder. (https://learn.adafruit.com/diet-raspberry-pi)Once you've got the majority of solder removed, use wick to clean it up. Do this by placing the wick over the area with solder, then pressing the widest part of the soldering iron tip against the wick to heat it up and cause the solder to flow into the wick. Finally, cut off the used wick! OK, not too hard - but suffers from requiring both hands which means putting down the iron while you yank some more wick out, then set it up, picking up the iron, doing the actual wicking, then putting down the iron again to cut the used parts. (https://www.youtube.com/watch?v=nDdgsjQDsXQ)If you're doing a lot of rework, the Menda/EasyBraid WickGun Dispenser (https://www.digikey.com/short/c4hztd83) makes this task easy by making the dispensing, positioning and cutting a one-handed task. The WickGun takes reels of braid of any width. Once loaded, turn the dial to dispense wick until you have a nice tail. Use the end of the wick against the spot you're reworking, and once done, press the trigger to snip off the used braid: easy-peasy-lemon squeezy! (https://www.youtube.com/shorts/wFx3pvNqeFk)The wicks themselves come with a variety of different solder widths and styles: from lead-free to no-clean and #1 to #5 widths with replacement cassettes available from Digi-Key as well. (https://www.digikey.com/short/vmq4q9vp) And Menda/EasyBraid WickGun Dispensers and Cassettes (https://www.digikey.com/en/product-highlight/e/easy-braid/wickgun-dispenser) are in stock for immediate shipment from Digi-Key, so you can order today and double the speed of your reworking by tomorrow afternoon.

According to Apple, Pippin was directed at the home market as "an integral part of the consumer audiovisual, stereo, and television environment." Pippin is based on the Apple Macintosh platform, including the classic Mac OS architecture. Apple licensed the Pippin technology to third-party companies. Bandai Company Ltd. developed the ATMARK and @WORLD models, and focused them on the gaming and entertainment business in Japan, Canada and the United States. The Apple Pippin platform was named for the Newtown Pippin, an apple cultivar, a smaller and more tart relative of the McIntosh apple (which is the namesake of the Macintosh). According to Apple, it intended for Pippin to be more than just a platform for game consoles. "Apple believes that over time Pippin will take many forms, including home telecommunication devices and much more. https://en.wikipedia.org/wiki/Apple_PippinAND a promo video from Apple and amazing commercial from Japan, check out our previous post with photos, details and more - all part of our MARCHintosh postin' !#MARCHinstosh #apple #gaming

Apple Interactive Television Box (1994)Before Apple TV, there was "The Apple Interactive Television Box", or ITV, also internally identified as STB (set-top box). Learn more about it, and check the photos and vid of ours (we have one!) ...Wikipedia -The Apple Interactive Television Box (AITB) is a television set-top box developed by Apple Computer in partnership with a number of global telecommunications firms, including British Telecom and Belgacom. Prototypes of the unit were deployed at large test markets in parts of the United States and Europe in 1994 and 1995, but the product was canceled shortly thereafter, and was never mass-produced or marketed.The Apple Interactive Television Box is based upon the Macintosh Quadra 605 or LC 475. Because the box was never marketed, not all specifications have been stated by Apple. It supports MPEG-2 Transport containing ISO11172 (MPEG-1) bit streams, Apple Desktop Bus, RF in and out, S-Video out, RCA audiovideo out, RJ-45 connector for either E1 data stream on PAL devices or T1 data stream on NTSC devices, serial port, and HDI-30 SCSI.[2] Apple intended to offer the AITB with a matching black ADB mouse, keyboard, Apple 300e CD-ROM drive, StyleWriter printer, and one of several styles of remote controls.The hard drive contains parts of a regular North American Mac OS 7.1.1 with Finder, several sockets for network connection protocols, and customized MPEG1 decoding components for the QuickTime Player software.https://en.wikipedia.org/wiki/Apple_Interactive_Television_Boxhttps://wiki.preterhuman.net/Apple_Interactive_Television_Boxhttps://pippin.fandom.com/wiki/Apple_Interactive_Television_Box#MARCHintoshVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #apple

This week, we're looking to upgrade our PyPortal design by replacing the M4 SAMD51 https://www.digikey.com/short/r34w4h33 + ESP32 https://www.digikey.com/short/hrqh8zh8 with an ESP32-S3 https://www.digikey.com/short/88rt8mvn which has RGB TTL display support. This means we can initialize larger displays than 320x240 - up to 800x480! We'll need to use just about all the GPIO but it's worth it for a gorgeous big display. These displays use a standard 40-pin interface. Let's see what Digi-Key has in stock for us to check out and we'll chat about different options available in these display types.See the chosen part on Digi-Key at https://www.digikey.com/short/c7nvbm9pVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #thegreatsearch #digikey @Digi-Key #deskofladyada

The Apple PowerCD (1993)From Wikipedia -"Apple PowerCD is a CD player sold by Apple Computer in 1993 and discontinued several years later. It was a re-badged Philips-designed product (Philips CDF-100) which was sold in addition to Apple's speakers and also included a remote control. The PowerCD was capable of reading Kodak photo CDs, data CDs and audio CDs. It can connect to Macintosh personal computers through SCSI and also to stereo systems and televisions."https://en.wikipedia.org/wiki/PowerCD...Does the Apple PowerCD (1993) work with the Apple AirPods Max (2020) headphones? Yes. Cable is needed, but works, sounds good.https://adafruit.com/marchintosh#marchintosh

This week's EYE ON NPI is a 1040 that is easier than filing out a 1040-EZ (https://www.irs.gov/filing/free-file-fillable-forms/free-file-fillable-forms-choose-the-right-1040-form), but will still get you a great return on your time investment: it's the NXP i.MX RT1040 Crossover MCU series (https://www.digikey.com/en/product-highlight/n/nxp-semi/i-mx-rt1040-crossover-mcu) an ultra powerful microcontroller that is designed to make it easy to add high speed processing without a lot of work or excessive BOM costs. The RT1040's ease of usability and implementation stands out when we look at the details, allowing you - yes you! - to have 500 MHz+ Cortex M7 processing on a low cost two layer board, and without a separate PMIC. We're featuring this chip as the big sister to the Metro M7 (https://www.adafruit.com/product/4950) that we're also releasing this week, so it's definitely an iMX party here at the 'fruit.The suggested way to program the iMX NXP series is to use NXP's IDE MCUxpresso (https://www.nxp.com/design/software/development-software/mcuxpresso-software-and-tools-:MCUXPRESSO) but you can also just use the NXP SDK with the arm-gcc toolchain in a command line or other IDE (https://developer.arm.com/Tools%20and%20Software/GNU%20Toolchain) If your application plans to use USB, we recommend checking out our TinyUSB implementation which has iMX RT10xx support (https://github.com/hathach/tinyusb) which compiles under arm-gcc as well, and includes many examples that you can build off of. We've also ported our TinyUF2 second-stage USB bootloader that has mass-storage for read-write of the flash memory (https://github.com/adafruit/tinyuf2).These chips are powerful and very integrated, so you don't need separate power management chips - also known as PMIC's - or SRAM but there are some tips and tricks to watch for about pin usage, the built in bootloader, and configuring the DC/DC converter. This handy video from NXP has some good quickstart tips (https://www.youtube.com/watch?v=mpb_mZknqrk) and each chip also has a suite of app notes for hardware implementation (https://www.nxp.com/products/processors-and-microcontrollers/arm-microcontrollers/i-mx-rt-crossover-mcus/i-mx-rt1040-crossover-mcu-with-arm-cortex-m7-core:i.MX-RT1040).There's many chips in the iMX RT family, as you move up and down you'll be trading package size, SRAM, and peripherals, for complexity and price. (https://www.nxp.com/products/processors-and-microcontrollers/arm-microcontrollers/i-mx-rt-crossover-mcus:IMX-RT-SERIES) The RT1040 sits nicely in the middle with 512KB of SRAM (the bigger chips are up to 1 or 2 MB), parallel TFT support, CAN bus, Ethernet, and two flexIO peripherals that can mimic various interfaces. But it doesn't have MIPI support, or a built-in camera interface, or a second USB port. Digi-Key does stock all of the rest if you so wish! (https://www.digikey.com/en/products/result?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANogBMADAJxMDsIAuoQA4AuUECAC%2BYoA)The NXP evaluation boards are fully featured and are recommended by NXP to get started (https://www.digikey.com/en/products/detail/nxp-usa-inc/MIMXRT1040-EVK/17141404) We tend to develop off the eval boards first, then using the schematics as a guideline for our own designs. While the BGA packaging is intimidating, it's available in two sizes: 9x9 and 11x11 with the same pinout - the smaller one has 0.65mm ball pitch, and the larger one has 0.8mm pitch, which means you can fan-out on a 2-layer PCB (https://www.nxp.com/docs/en/application-note/AN10778.pdf) or get roomy with a 4-layer. Other than a 3.3V power supply, a crystal and some passives, you only need a QSPI flash memory chip - we use the W25Q64 (https://www.digikey.com/short/0jpf8wmf) on our Metro M7 with great success.Best of all, both versions of the NXP iMX RT1040 chips are in stock right now for immediate shipment from Digi-Key! We suggest starting with the larger MIMXRT1042XJM5B (https://www.digikey.com/short/jv9qjdtv) and the RT1040 EVK (https://www.digikey.com/en/products/detail/nxp-usa-inc/MIMXRT1040-EVK/17141404) Huzzah, the chip shortage is over - so order today and you'll be blazing along with a Cortex M7 at 500 or 600 MHz by tomorrow afternoon.

One of our new Feather designs will sport a full-size HDMI connector that can be used to connect to DVI displays. While the RP2040 itself does not have a native DVI driver, you can sorta-bitbang your way to success using the PicoDVI library (https://github.com/adafruit/PicoDVI). Like USB, there are standardized connectors, so it's easy to find a good range of suppliers that will give us full-sized HDMI connectors. Like USB Type C, you can also use the connector in a pick and place line and with some good paste deposition, skip the wave or selective solder step for the through-hole mounting tabs.See the chosen part on Digi-Key at https://www.digikey.com/short/0qbjpcbqVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #thegreatsearch #digikey @Digi-Key

This week's EYE ON NPI is sixty-giga-cool with 60 giga-Hertz of Doppler radar sensing. It's the Infineon XENSIV™ BGT60LTR11AIP Radar and Shield2Go Dev board (https://www.digikey.com/en/product-highlight/i/infineon/xensiv-bgt60ltr11aip-radar-shield2go), featuring Infineon's super-low-power 60 GHz Doppler radar sensor with antenna-in-package (AIP). This device is an ultra-tiny 60 GHz radar-on-a-chip sensor that even includes the normally-large antenna's seen in most Doppler radars baked right into the top!RADAR is literally "Radio Detecting And Ranging" - a way of bouncing 'high frequency' electromagnetic waves off of objects to detect the reflection. We're familiar with radar (https://en.wikipedia.org/wiki/Radar) in a few contexts: originally developed for military use, it worked great for detecting metal things in the sky (airplanes) as they would approach a city to possibly bomb it. We still use it a lot in military contexts: detecting planes, bombs, boats and submarines. It's also super handy in domestic contexts like air traffic control, if you can detect planes you can verify their positions and make sure each one comes in or out of the airport without collision. Radar is also useful for weather pattern detection (although this sensor isn't good for that purpose, just a fun fact for you to know).Another common purpose for radar you're probably familiar with is the dreaded speeding radar gun (https://en.wikipedia.org/wiki/Radar_speed_gun) a small-enough-to-be-handheld radar device that can be pointed at a car to determine its speed without requiring a difficult-to-calculate "time between two points" measurement. These reliable devices are apparently now are replaced with LIDAR based ones!Most folks who have used IR sensors, Time of Flight, or sonar sensors can understand how to detect an object by counting the delay between sending a signal vs when it's received and dividing by the wavelength. How can you determine velocity - normally you'd need to detect location twice, then determine the time between the two locations whereas radar can do it one measurement. This is thanks to the 'Doppler Effect' (https://en.wikipedia.org/wiki/Doppler_effect) the same scientific principle that causes ambulance sirens to be higher pitch as they approach and lower pitch as they drive away from you due to the 'bunching up' of the waves as the wave source moves. Likewise with Radar, the frequency will shift slightly depending on the speed of the object, which can be detected by calculating the minute variation in frequency.What's particularly neat about this sensor is that, compared to other radar modules that have a trace PCB antenna, the antenna is embedded right into the chip itself. Compare that with the BGT24 modules that come on a PCB with an 'Arduino shield size' antenna (https://www.digikey.com/short/dn48cfhr) The BGT60LTR11AIP comes as a BGA component, with a lot of pins! Thankfully, Ultra Librarian has a package footprint for this part that Digi-Key helpfully provides, so you can import and get started with integration quickly (https://app.ultralibrarian.com/details/2071C153-54B1-11EC-9033-0A34D6323D74/Infineon/BGT60LTR11AIPE6327XUMA2?ref=digikey)There's also a few different development boards available, including a tiny module 'shield' SHIELDBGT60LTR11AIPTOBO1 (https://www.digikey.com/en/products/detail/infineon-technologies/SHIELDBGT60LTR11AIPTOBO1/16343839) that requires only 4 pins: power, ground, output direction and output motion detect (https://www.infineon.com/cms/en/product/evaluation-boards/demo-bgt60ltr11aip/) There's also a fancy "SHIELD2GO" board (https://www.digikey.com/en/product-highlight/i/infineon/xensiv-bgt60ltr11aip-radar-shield2go) that has all of the user-useful GPIO and SPI interface accessible, and a full demo dev kit that also includes the mini shield. (https://www.digikey.com/en/products/detail/infineon-technologies/DEMOBGT60LTR11AIPTOBO1/13563722)There are two ways to integrate the sensor: via simple two-GPIO connection where one pin is motion detect and the other is direction, or via a more complex SPI protocol. The SPI interface is documented in the User's Guide (https://www.infineon.com/dgdl/Infineon-AN625_userguide_BGT60LTR11AIP-ApplicationNotes-v01_05-EN.pdf) and the Infineon bgt60 github repo (https://github.com/Infineon/sensor-xensiv-bgt60trxx) has some portable C code that just needs a hardware abstraction layer implemented in order to be used with your favorite platform.For an ultra-tiny Radar module-on-a-chip that has low-power, low-cost and ease-of-integration, you can pick up the Infineon XENSIV™ BGT60LTR11AIP (https://www.digikey.com/short/jv0b0n0z) at Digi-Key. It's in stock right now for immediate shipment, and available in any quantity on cut-tape or reel: order today and you can be Dopplering by tomorrow afternoon.

This week's Great Search is for a replacement for our Venerable PAM8301 class D amplifier (https://www.digikey.com/en/products/detail/diodes-incorporated/PAM8301AAF/4033366), a part we've used in a ton of boards to act as a mini amplifier for SMT magnetic buzzers (https://www.digikey.com/short/1w0t87ww) for making beeps and simple sound effects. It's low cost enough, it is only a little more expensive than a Class AB, but without needing large blocking caps. Sadly, it's now NRND, so let's find another similar chip that we can use to keep our designs alive and kicking!See the chosen part on Digi-Key at https://www.digikey.com/short/p8p81h7fVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #thegreatsearch #digikey @Digi-Key

This week's EYE ON NPI won't have you singin' the blues about Bluetooth stack development. It's InPlay IN100 NanoBeacon™ Bluetooth® Low Energy Beacon SoC (https://www.digikey.com/en/product-highlight/i/inplay/in100-nanobeacon-soc), an ultra-low cost way to make sensor beacons for data collection, with no coding required! These flash-less chips are packed with peripherals that can be configured with a desktop tool and then burned into OTP EEPROM memory. That makes them both reliable and very inexpensive, so they're great for distributed sensors that may end up getting damaged or lost. They're also great for when you want to get something into production super fast and don't want to spend time learning Bluetooth SDKs or wireless stacks.Bluetooth LE is a low-power 2.4GHz protocol that has some nice 'connection-less' capabilities. Unlike WiFi and cellular, BLE has the ability to act like a 'beacon' (https://learn.adafruit.com/introduction-to-bluetooth-low-energy) where data is blipped out for anyone to listen to. (https://learn.adafruit.com/alltheiot-transports/bluetooth-btle) Note that in beacon mode, there's no wireless reception happening - and because there's no need to listen for packets, the beacon can go into very, very low power usage because it just has to wake up, send the beacon out, and go back to deep sleep. Receiving requires a lot more power because you have to be listening at all times. Beacons are what are used in "lost and found" tags, for asset or people tracking, as well as distributing URLs.(https://en.wikipedia.org/wiki/Bluetooth_Low_Energy_beacon)Normally, folks would use a common BLE chipset such as nRF, Dialog, or TI - often these come with a ARM Cortex chip inside that can run a BLE stack. The stack can either be the in-house brand such as the nRF SDK (https://www.nordicsemi.com/Products/Development-software/nrf5-sdk) or a third-party like Zephyr (https://docs.zephyrproject.org/3.1.0/connectivity/bluetooth/api/index.html) but either way you have to write some code and burn it into the chip. You also have to learn how to manage the low power modes and debug your code.For many basic beacon projects, such as measuring a digital, analog, or I2C sensor - the IN100 is pretty amazing: all the low power and SDK stuff is done - you just have to configure each board and burn in the settings. The good news is that you can deploy your beacons or sensor nodes super fast, and because the core is designed to only do this one thing, the chips are really really cheap. Like 40 cents per piece cheap! (https://www.digikey.com/en/products/filter/rf-transceiver-ics/879?s=N4IgTCBcDaIJYDsCMAGFIC6BfIA) Your entire BOM for a beacon product could easily be under $1 including the coin battery. They're available in 10-DFN IN100-D1 (https://www.digikey.com/short/3jmnp8r3) and 18-QFN IN100-Q1 (https://www.digikey.com/short/mtp92d50) depending on how many GPIO you need.Since the trade-off for the ultra-simple design and low BOM cost is OTP memory, we recommend getting the IN100 evaluation kit (https://www.digikey.com/short/0q0jwwqq) which comes with a programming dongle and three beacon boards fitted with the QFN version of the IN100. Then download the cross-platform configuration tool (https://inplay-tech.com/nanobeacon-config-tool) and follow the YouTube video tutorials they've filmed to learn how to configure the beacons for different advertising modes. (https://www.youtube.com/watch?v=dJfQ059KzRg) Don't worry about making mistakes: you can always run from RAM to iterate the design before finally burning it into the OTP! And even if there are errors, the InPlay IN100 NanoBeacon Eval Kits are inexpensive (https://www.digikey.com/short/5z920hrj). Once you're ready to go into production, the individual chips are plentiful and low cost (https://www.digikey.com/short/97773wh3) so you can get into production almost immediately.The InPlay IN100 NanoBeacon Eval Kits (https://www.digikey.com/short/5z920hrj), IN100-D1 (https://www.digikey.com/short/3jmnp8r3) and IN100-Q1 (https://www.digikey.com/short/mtp92d50) are all in stock right now for immediate shipment from Digi-Key - available nowhere else! If you're curious to try this no-code BLE beacon chipset, order today and you can be Bluetooth Beacon'ing by tomorrow afternoon!

This week's EYE ON NPI is on the right traq, ready to attaq, and gets no flaq: it's the Digilent USB-2001-TC Single Channel Thermocouple Measurement Device, otherwise known as a single-channel DAQ! (https://www.digikey.com/en/product-highlight/d/digilent/usb-2001-tc-single-channel-thermocouple-measurement-device) These rhymes may get me some flaq, but we can't help it, our lips smaq when we see a good DAQ. And this one is deliciously small and single-purpose. We wish we had one of these a few weeks ago when we wanted to check our reflow oven to calibrate the temperature curve!While we are featuring this particular DAQ board that is good for high temperature measurements via a thermocouple, there's a whole family of boards from Digilent/NI (https://www.digikey.com/en/products/filter/data-acquisition-daq/1017?s=N4IgTCBcDaICIEsDmCA2BTAdgFwAS4FcBnAIxAF0BfIA) All manufactured and supported by MCC (https://www.mccdaq.com/) - the OEM for this series. The others are a mix of Ethernet, Raspberry Pi or USB controlled ADCs & DACs (https://www.mccdaq.com/data-acquisition/low-cost-daq) with 12 to 24 bit resolution, and up to 500 kS/s.The USB DAQ board does not come with a thermocouple itself, you'll need to get a standard K, J, etc. type (https://www.digikey.com/en/products/filter/temperature-sensors-thermocouples-temperature-probes/513) and also have it with a mini thermocouple plug which is available on Digi-Key if you are getting bare thermocouple wires (https://www.digikey.com/short/9hbfrwht). The thermocouple wire can come on huge spools if desired: spot weld one end that will be attached to the hot thing being measured, and then screw the other ends into the mini plug.Inside is Silabs C8051F343 (https://www.digikey.com/en/products/detail/silicon-labs/C8051F343-GQ/990818), Analog Devices ADUM5401 (https://www.digikey.com/en/products/detail/analog-devices-inc/ADUM5401ARWZ-RL/1873647) isolator, and an AD7785 (https://www.digikey.com/en/products/detail/analog-devices-inc/AD7785BRUZ-REEL/1644783) 20-bit ADC.Data can be captured using the DAQami software available for download on Windows (https://www.mccdaq.com/daq-software/DAQami.aspx) although it seems like you can also interface through the hardware using an API or Python (https://www.mccdaq.com/MCC-Software.aspx). Of course, since its a Digilent / National Instruments product, it's also fully supported within LabVIEW. (https://www.mccdaq.com/daq-software/universal-library-extensions-lv.aspx)While normally we're happy to talk about individual interface chips for DAC/ADC/Thermocouple interfacing (https://blog.adafruit.com/?s=%23eyeonnpi+temperature), and there's tons of Adafruit guides on how to DIY this kind of data acquisition (https://learn.adafruit.com/search?q=thermocouple), it's pretty nice to have a ready-to-go USB device that streams data without having to open up an IDE or write any code at all. Particularly for automations where the data has to go into a computer anyways, it can save a lot of time to now cobble together your own setup.The Digilent USB-2001-TC Single Channel Thermocouple Measurement Device (https://www.digikey.com/short/23v0hp90) and other Digilent/MCC DAQs (https://www.digikey.com/en/products/filter/data-acquisition-daq/1017?s=N4IgTCBcDaICIEsDmCA2BTAdgFwAS4FcBnAIxAF0BfIA) are stocked by Digi-Key! They sold out while writing this EYE ON NPI, but they'll have more soon, so sign up to be notified by email when they come back in stock.

We're continuing on our quest to replace the brains of the Baby Einstein Take-a-Long Tunes toy with something that can play Autechre or Bjork. Since the last video, Mr Ladyada has scanned in the PCB so that we can start to trace the outlines. We used simple computer image editing software to delete the background, rotate it so its straight, and convert it to monochrome. After importing, we traced out the slots and holes so that our new PCB will be able to fit right in place. Now its time to spec some parts! Our big decision is what chipset to go with: we can't get SAMD21 or SAMD51's anymore, so our best bet is ESP32 series or RP2040. Since the case does not have a USB slot we have to have the USB port for programming on the inside and a few screws removed to do so. So we figured a WiFi-capable chip would be nice since then it could be programmed wirelessly. So we're gonna start with trying to place an ESP32-S2 (https://www.adafruit.com/?q=esp32-s2&sort=BestMatch) inside. For audio output we'll use the MAX98357 mono I2S amp (https://www.adafruit.com/product/3006) since the DAC on the -S2 isn't very good for audio playback. Now we just have to fit it all in and route the PCB!Part 1 is here - https://youtu.be/FT0PbVF_aeYVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#babyeinstein #toys #esp32 @BabyEinstein @EspressifSystems

On this week's Great Search, we're on the lookout for monophonic I2S amplifiers that we can use for our toy hacking project. Traditionally we've gone with the MAX98357 (https://www.digikey.com/short/cvn3052m) which is a rock-solid I2S Class D amplifier that we have used in boards and breakouts for many years. Are there any other options we should consider? Let's take a look at Digi-Key for some possible options that we'll try out!See the chosen part on Digi-Key at https://www.digikey.com/short/r8p3nw7tVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #thegreatsearch #digikey @Digi-Key

Parallel-data camera breakouts are common, but we wanted to design a better one for video and image hacking. Details like i2c pullups, built-in 24mhz oscillator, auto-focus motor power supply, and a camera heatsinking power plane!Many cameras have the same FPC cable and pinout, making them easy to swap in and out. This one is a wide-angle OV5640, but the board will work with OV2640 and others.An ESP32-S2 Metro is used to grab frames from the camera and blit them to a 1.3" TFT screen.Check out the wide-angle OV5640 camera here: https://www.adafruit.com/product/5673.

we had some time this weekend to write the floppy featherwing tester code. this board tests the inputs and outputs, that go through two level shifters so that the signals TO the floppy drive are shifted up to 5V and the signals FROM the floppy drive are lowered to a safe 3V. for this final version we added a write-protect switch that adds a hardware interlock protection to avoid accidentally writing to floppy disks when you want to only read from them. more floppy stuff will be making it into the shop soon!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#floppy #retro #adafruit

This week's EYE ON NPI is your next 8-bit microcontroller, it's STMicroelectronics STM32C0x1 Series Entry-Level MCU (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stm32c0x1-series-entry-level-32-bit-mcu) that gives developers a 32-bit Arm Cortex M0+ microcontroller at 8-bit microcontroller prices. These aggressively priced microcontrollers come just at the end of a 2-year chip shortage, so if you've been holding back a design, it could be a great time to swap out your 8051-based or other 8-bit microcontroller for a powerful Cortex M0+ that can use ST's supported firmware libraries and IDE.Most developers go with 8-bit microcontrollers to get a few basic needs met: maybe a few timers, ADC, GPIO and I2C or USART for interfacing. The benefits are low complexity in design, for example no crystal needed because there's an internal trimmed-RC oscillator, or a simple power supply with only one power pin so you don't need multiple regulators. 8051-based (https://en.wikipedia.org/wiki/Intel_8051) microcontrollers are popular as cores for their ultra-low cost and fairly-low power usage. But the programming environment tends to be archaic, and 8-bit code compiles chunky especially when dealing with floating points (https://www.wikihow.com/Convert-a-Number-from-Decimal-to-IEEE-754-Floating-Point-Representation) or large-integer math. If you ever have to do anything more complex like interpolate values or perhaps run a digital filter on your data, an 8-bit micro will be really annoying. Updating to the 32-bit, particularly the Arm Cortex line, will open up the whole universe of optimized and standardized libraries that CMSIS provides (https://developer.arm.com/tools-and-software/embedded/cmsis)The STM32C0 series is the lower-powered version of the STM32G0 series (https://www.digikey.com/en/products/result?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANogBsAHAEysgC6hADgC5QgQAXxFA0 - both are Cortex M0+ chips, but the C0 runs at 48MHz instead of the G0's 64 MHz. The chips are otherwise pin compatible at the low pin-count-end of 8 to 48 pins, the G0 keeps going up to 100 pins. There's 9 different packages, that also have increasing amounts of FLASH/SRAM, with either 16 or 32K of flash and 6 or 12K of RAM. For peripherals you'll get plenty of GPIO, DMA, four 16-bit timers, a 12-bit ADC with 13 channels and surprisingly-high 1.7 MSPS. SPI, I2S, two USART and one I2C. Note there's no USB on the C0 series, for that you'll need to upgrade to the STM 32G0x1 (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stm32-g0)We haven't featured a lot of microcontrollers on EYE ON NPI lately because we prefer to tell you about parts you can order immediately. The good news about STMicroelectronics STM32C0x1 Series (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stm32c0x1-series-entry-level-32-bit-mcu) is that they're all in stock right now for immediate shipment (https://www.digikey.com/en/products/filter/embedded/microcontrollers/685?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANrgAMAnAExgsgC6hADgC5QQIAL6igA) - in a wide variety of packages and memory options. And if you want to start verifying the parts for your firmware immediately, there's the STM32C0116-DK dev kit (https://www.digikey.com/en/products/detail/stmicroelectronics/STM32C0116-DK/17074591) in stock. Order your STM32C0x1 Series chips or developer kit today, and you can be revising your 8-bit microcontroller design to a 32-bit glow-up by tomorrow afternoon!

On this week's The Great Search, we're looking for a P-Channel MOSFET in a small SMT package to replace the classic SOT-23 one we use for all our Feathers. In this case, we're making a very compact board, so we need a smaller package! We've traditionally used the DMG2305 (https://www.digikey.com/short/4mtb0tz8) or DMG3415 (https://www.digikey.com/short/jdpmrcvc) as a high-current 3 or 4 Amp, 20V+, low 1Vgth, and low RdsOn of 50mOhm or less.

This week we had to do some reworking of an ESP32 module that has pads underneath. When this happens, we have to apply paste using a syringe to the pads and then heat up the PCB and module together with a hot-plate or hot-air machine. Solder paste syringes are super handy to have and have a long shelf life. Let's look at some options on Digi-Key and which ones you'd pick based on your rework or solder needs!See the chosen paste on https://www.digikey.com/short/8v23v17zVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #thegreatsearch #digikey @Digi-Key

This week's EYE ON NPI is clipped in and ready to roll, with WAGO 2601 Series Super-Compact PCB Terminal Blocks (https://www.digikey.com/en/product-highlight/w/wago/2601-series-pcb-terminal-blocks) available in both horizontal (https://www.digikey.com/short/twfw2cjh) and vertical types (https://www.digikey.com/short/7t4fp5b5) and a wide range of widths. These terminal blocks feature WAGO's famed snap-lock levers for quick and secure connectivity with certified current handling that can support your high-current and high-voltage setups and a wide range of wire gauges.Terminal blocks (https://www.digikey.com/en/products/filter/wire-to-board/371?s=N4IgTCBcDaIC4FMBOBbAlgOwIYBsAEARjgPYDGA1gM4gC6AvkA) are super common to find on any electronics product, especially used for power and motor connections where you need high current/voltage capabilities because every day connectors like JST PH's (https://www.digikey.com/en/products/detail/jst-sales-america-inc/S4B-PH-SM4-TB-LF-SN/926657) are only rated for a few Amps and it's common to need 5A or more for power/motor connectivity. Terminal blocks are also inexpensive, easy to use, and don't require custom connectors or crimping: any stranded or solid core wire will fit and work and you can rearrange wire order if necessary.Traditionally, we've used the side-entry-with-top-screw type of terminal block -- Digi-Key has a video that describes all the different types of terminal blocks you may encounter here (https://www.digikey.com/en/videos/c/cui/the-ultimate-guide-to-terminal-block-selection). However, it can be easy for folks to misuse them by not tightening enough, or accidentally inserting outside of the block's "mouth". Also, sometimes they're Phillips screw, sometimes they're Flathead - or folks end up stripping them by over-tightening or having the wrong size driver.These WAGO 2601 Series Super-Compact PCB Terminal Blocks (https://www.digikey.com/short/bnw5b3pz) are a super-fancy upgrade to classic terminal blocks. They're still the 3.5mm pitch of compact terminal blocks, but come with WAGO-quality levels that can be lifted with a finger to open the mouth, and snapped down in a moment. Two through-hole pins per contact give good mechanical stability when hand, selective or wave-soldered onto your board. Wires can be 26 to 16 AWG, and solid core wires can even be push-inserted in as long as they are 20AWG or thicker. (https://wago.priintcloud.com/datasheets/2601-1104/en_US/e75ede034608c38f290f16f29cacc6cc) Each contact can handle 300V and 10A, and the terminals are UL/IEC rated so you can trust their power capacities! In case you're wondering, if WAGO tests to figure out what happens if the ratings are exceeded, may we point you at this entertaining video (https://www.youtube.com/watch?v=eg6VPucscxI) where the engineers got to turn the WAGO block into a heat lamp!Best of all, the WAGO 2601 Series Super-Compact PCB Terminal Blocks (https://www.digikey.com/en/product-highlight/w/wago/2601-series-pcb-terminal-blocks) are available and in stock right now at Digi-Key for immediate shipment in a range of widths and orientations. Upgrade your design for these awesome terminal blocks to make connections reliable and error-proof, if you order today you'll have any size you like by tomorrow afternoon!

Full tutorial: https://learn.adafruit.com/light-up-your-costume-with-noods/overviewAdafruit Noods are little noodles of light. They're as simple to use as a regular LED - connect one end to power and one end to ground, and they light up and glow. They're incredibly bendy and flexible, making them just perfect for small subtle costume details. A nood will last for hours on a single coin cell battery, with no big noisy EL-wire inverter to manage.This video shows how to hook up one n00d.

This week's Great Search is on the look-out for a navigation switch. These are like 'joysticks' or 'thumbsticks' but are mechanical not analog in nature. They're great for small interfaces where you want a directional navigation with up/down/left/right and select but without a ton of buttons.

Little tact buttons are sprinkled throughout our designs: reset buttons, or mode selects, they're compact yet fairly easy to use. Historically we have called these "KMR2" buttons (https://www.digikey.com/en/products/filter/tactile-switches/197?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANrgBsATAKwAMIAuoQA4AuUECAC%20ooA). Let's check what's available at a good price for folks who want to use these in their projects. In particular, we're going to spec a mini tactile button with a larger-than-usual actuator which we are growing fond of.See the chosen part on Digi-Key https://www.digikey.com/short/m027prz5Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #thegreatsearch #digikey @Digi-Key

one of the successes we had with the adafruit feather / featherwing format is that we spent a year making a new feather board once a week - for a total of 50 boards and accessories. for 2023 we're seeing a lot of folks using the raspberry pi pico and pico w (https://www.adafruit.com/category/875) so we were thinking we could 'port' the designs over from 'wings to 'bells. we already did the proto cowbell (https://www.adafruit.com/product/5200) and now we're designing a port of the adalogging 'wing (https://www.adafruit.com/product/2922) which adds a QT port, RTC with battery, and microSD card. the battery holder just barely fits!Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #feather #raspberrypi
we've got a bunch of boards in the QT Py format on the adafruit shop (https://www.adafruit.com/?q=qt+py&sort=BestMatch) they are all adorable, small and great for tiny projects. we've got SAMD21, RP2040, ESP32 of various types...chatting about possible projects we thought it would be a good idea to have a BFF add-on board (https://www.adafruit.com/?q=bff&sort=BestMatch) that can make a quick IoT button. this PCB has a 12mm SMT tactile switch and a neopixel, and that's it! it's low cost and easy to use, great for basic projects that just need one input and a colorful feedback output.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#arduino #adafruit #iot @SeeedStudioSZ @Arduino
we spent this evening updating this cute menorah project we've had for over a decade, from an Arduino UNO to run on a RP2040 QT Py board (https://www.adafruit.com/product/4900) with our prototype "IoT Button BFF" board to increment through the nights. we used PaintYourDragons' LED candle flicker code from this halloween project (https://learn.adafruit.com/circuit-playground-jack-o-lantern) and sorta mixed it with Liz's NeoPixel menorah project from last year (https://learn.adafruit.com/neopixel-menorah). this project predates NeoPixels - all we had were WS2801's at the time! we think it looks pretty nice now, and its a lot more compact :) #Hanukkah #menorah #circuitpythonVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

we crank out a lot of rp2040 microcontroller boards and so we have to be able to program them very fast and very reliably. historically we used a teensy 3.6 to run our programmer+tester 'brains' - in particular we liked that it had USB host support and a microSD card slot so we could store the target UF2 and then burn it over the MSD interface. it's very hard to find teensy 3.6's and we ran out a few months ago. yet, we cannot let that stand in the way of us making new hardware! thanks to Thach's hard work, we have added USB host bitbang support to TinyUSB so that the RP2040 can pretend to have a second USB port and it works very well! check it out here https://github.com/adafruit/Adafruit_TinyUSB_Arduino/tree/master/examples/DualRole if you want to play with USB host on a microcontroller that is available to purchase :) meanwhile, we'll be revising our testers to use the pico and our new almost-all-SMT brains board.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------#adafruit #raspberrypi #arduino @raspberrypi @Arduino

We really dig the portable / wearable elvie pumps (http://elvie.com/) for daily use. like other battery powered pumps, they need to be charged daily, sometimes multiple times! we like to keep them topped up all the time so that we don't have to worry about the battery conking out mid-pump. however, the micro USB charging port is really annoying, especially at 4 am! so we upgraded our set with these magnetic tip USB cables (https://www.adafruit.com/product/5520). the micro USB tips (https://www.adafruit.com/product/5523) go in each elvie, and then we can simply snap the cable in place without fiddling with the rubber gasket or cable orientation.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------@ElvieOfficial #elvie #adafruit #usb

Full tutorial: https://learn.adafruit.com/neopixel-remote-ir-control-with-wled/RGB LED lighting strips are everywhere. Many of these strips come with a handy infrared (IR) remote control that will allow you to select different colors, change brightness, and fade from one color to the next. They're very easy to install and use, but can be rather a disappointment for the discerning LED connoisseur.The pre-programed animations and available colors on these cheap RGB strips are very basic. You can get ordinary solid colors or annoying blink modes, but buttery smooth subtle color shifts, gradients, and beautiful mesmerizing animations are far beyond the reach of these "dumb" RGB strips. For subtlety and beauty, you need NeoPixels - "smart" individually addressable LED lights that can be controlled with code.This guide will show you how to get beautiful, subtle NeoPixel animations up and running and controllable with a simple IR remote in minutes, with no coding required. The free, open-source WLED app allows you to create your own NeoPixel animations, choosing from hundreds of effects and color palettes. Automatically map your custom animations to the buttons on your IR remote, so you can choose solid colors or run your beautiful custom animations from the same controller.Visit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------

This week's EYE ON NPI comes to us from the brilliant wireless engineers at Nordic Semiconductor - it's the Nordic nRF9160 System-in-Package with Integrated Cellular and GNSS (https://www.digikey.com/en/product-highlight/n/nordic-semi/nrf9160-sip). You know them for their popular nRF52 series of microcontrollers that have integrated Bluetooth LE - they're the market leaders for BLE development and support, with excellent software and low-power capabilities. A few years ago they decided to start branching out from their hit products and into more wireless IoT transports, like cellular and, more recently, WiFi (which perhaps we'll cover in a future EYE ON NPI!).
The nRF91 series (https://www.nordicsemi.com/Products/nRF9160) is the Nordic Semi flagship cellular line, but it's different than most cell modules we've used. Normally you get a modules say from Quectel, and interface to it via USB or UART - sending AT commands (https://en.wikipedia.org/wiki/Hayes_command_set) and parsing the responses. That's fine and good but means that there's often a secondary microcontroller that has to do the work, and there's always a lot of work to do that parsing and command handling.
What we like about the nRF91 is that it comes as a cute SIP package, much smaller than most modules, and integrates an ARM Cortex M33 with 1MB of flash, 256KB of RAM that you can program directly. This is familiar to folks who use the nRF52 series, where the BLE stack is integrated in hardware/firmware through the 'SoftDevice' system. (https://infocenter.nordicsemi.com/topic/ug_gsg_ses/UG/gsg/softdevices.html) You get all the hardware-interfacing you need with 32 GPIO, 12-bit ADC, RTC, SPI, I2C, I2S, UART, PDM and PWM which means that ideally you can develop your entire product on a single chip without need for external peripherals or drivers.
The nRF91 comes in three flavors: nRF9160-SIAA (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF9160-SIAA-B1A-R7/13533593) which has only LTE-M cellular support, nRF9160-SIBA (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF9160-SIBA-B1A-R7/13533587) which has only NB-IOT support, and the nRF9160-SICA (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF9160-SICA-B1A-R7/13533588) which has LTE, NB-IOT and GNSS. Each one has is pin-compatible but has different price levels, so pick the one that fits your budget and wireless needs. Note there's full 700MHz - 2.2GHz band support on each version of the SIP, so you don't have to order different SIPs for North America, South America, Asia, Europe, Africa, etc. There are global certifications available that you can look up to make sure you are cleared to integrate in any country you may need (https://www.nordicsemi.com/Products/Low-power-cellular-IoT/nRF9160-Certifications)
The Nordic nRF9160 modules have been out for a few years, so there's lots of development boards you can use. For example, Nordic's in-house made dev board is fully featured with every add-on needed, plus Arduino-compatible headers (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF9160-DK/9740721). There's also the extremely well-named Nordic Thingy 91 (https://www.digikey.com/en/videos/n/nordic-semiconductor/introducing-the-nordic-thingy-91-cellular-iot-prototyping-platform) which is a great dev kit for designing compact, battery powered, sensor-filled prototypes. The prior is better when you want to have JTAG headers and connect lots of external hardware, the latter is good if you happen to have some overlap with the built in hardware and want to prototype user experiences. If you are a Feather Fancier, there's an nRF9160 Feather (https://www.digikey.com/short/94tc2w84) that you can use to make lightweight portable designs that plug into FeatherWings.
Best of all, all three versions of the nRF91 (https://www.digikey.com/en/product-highlight/n/nordic-semi/nrf9160-sip) are in stock now for immediate shipment from Digi-Key! We recommend starting with the full-featured nRF9160-SICA (https://www.digikey.com/short/j97r25p7) as you can always place the final design with one of the pared down SIAA or SIBA when you go to production. Order today for instantaneous shipment, you'll have these in your hands by tomorrow afternoon.

This week we worked on redesigning a very old breakout board, the I2C/SPI LCD Backpack: https://www.adafruit.com/product/292 . We're going to add plug-n-play STEMMA QT ports and since we're doing a bit of work, why not fix up a bunch of other things that have been annoying to us? For example, the trim pot is inexpensive and reliable but a bit annoying to turn unless you have just the right screwdriver. Let's look for an alternative that's easier for folks to adjust!

Music by Bartlebeats https://soundcloud.com/adafruit
This week's EYE ON NPI is a bright-eye'd and bushy-tailed go-getter, who can juggle multiple tasks at once: it's the Richtek RT4539 36 V I²C Controlled 6-Channel WLED Driver (https://www.digikey.com/en/product-highlight/r/richtek/rt4539-36-v-6-ch-wled-driver)! This chip can do it all: it's a boost converter, it's a calibrated constant-current sink, it's a PWM controller, it's a gamma-corrector, and it's got I2C for controlling all the settings. It's designed for use in laptop or tablet backlight control, and all the little extras that were designed in make it excellent for other sorts of lighting drives - just cause it says its for white LEDs doesn't mean you have to only use it for that purpose!
The first feature of this chip is the boost converter. Since most LED backlights (and even some large LED clusters) have the LEDs in series to keep them current balanced, we often need to boost the battery voltage up to 20V+, this chip can go up to 36V output from 2.7 to 24V input - which means it can handle up to 10 LEDs at 3.3V forward drops, and still have a little headroom. The boost FET switch is internal so only an inductor and diode are required. Since this is a constant-current chip, the output voltage will fluctuate as necessary to support the current draw needed. The booster frequency can be adjusted over I2C to balance flickering/beat frequencies and efficiency vs low power usage.
The second feature is the constant current string driver. As mentioned, large backlights try to string LEDs together to balance the current, but once you get past about 3-5" diagonal, there's usually more than one string. So now you want to make sure each string is balanced. Inside are comparator/differential drivers that use matched transistors and resistors with current mirroring setup to make sure you get the same exact current through each string.
The third feature of the RT4539 is the PWM driver (https://en.wikipedia.org/wiki/Pulse-width_modulation). Yes you can reduce the current through the strings but its easier to get a wide range of brightness values by keeping a constant current and then PWMing the output sink drivers. It's normal to see linear PWM drivers: where you can go from 0-255, say for 8-bit control and that translates to a linear duty cycle. This chip goes above-and-beyond and provides an exponential "gamma corrected" (https://learn.adafruit.com/led-tricks-gamma-correction) output control curve if desired. This gives a more natural and useful brightness curve where there's more granularity at low brightness values, often used for night modes.
The fourth (and final?) feature to highlight is that all of the settings for the capabilities are available over I2C! From the booster frequency to sink current, to the PWM style and duty cycles to extras like smooth dimming transition features, there's a register map for easy configuration and adjustment, making his chip trivial to integrate into any design with a microcontroller or microcomputer.
The Richtek RT4539 (https://www.digikey.com/short/th42j03z) is super-duper new, so it's not yet available for purchase on Digi-Key's website - keep an eye out for when this chip becomes available or contact your Digi-Key sales rep and they'll be able to wrangle you some samples!

Tutorial Link: https://learn.adafruit.com/light-up-costumes-in-harsh-environments/
Light-up costumes using LEDs are delicate. Wires break, connectors, fail, and dust or water can get into the tiniest cracks in your enclosure, causing short circuits or rust.
And yet, most of our LED costumes are dreamed up, built, and created to be taken into harsh environments. We want to wear them to festivals in the desert and have them glow all night. We want to dress our wiggling, squirming kids up in lights so they can trick-or-treat on Halloween Night. We need our costumes or art cars to stand up to assault by excited bystanders who can't resist poking, touching, and tugging on our beautiful creations. They need to be able to weather windstorms and rainstorms, long hugs from strangers in the dark, immersion in cuddle puddles, or pole dances on a moving art car, deep in the playa. They need to work every time we turn them on, without an hour's worth of repairs needed after every appearance.
This tutorial will give tips and tricks on design, build, and maintenance for costumes that Will Not Break. I'm using my favorite example: my light-up swimming mermaid tail.
You think the playa is a challenge? Try wearing your LED costume in the ocean.

For the RP2040 SCORPIO, we have 8 level-shifted outputs that come out the end, and they may end up connecting to a looooong wire strand before hitting that first NeoPixels. To avoid ringing, we can add a small in-line resistor (say 100 ohm). But we are really tight on space! How can we fit 8 resistors into a 2mm wide strip of space? Behold the magic of 0804 resistor packs! We love packs for space saving and possibly even cost saving when manufacturing.

With prices of TFTs back down to earth we're doing a lot of revisions and updates for our TFT breakouts. This week we looked at the 2.8" TFT with capacitive touch. We revised the board to go from having SOIC to TSSOP 74VHC245 level shifters, and with the space left over added an EYESPI connector. We're also trying to wrap the RP2040 Scorpio feather - this is an RP2040 board that is designed for driving 8 strands of NeoPixels with the NeoPXL8 library.

FULL TUTORIAL: https://learn.adafruit.com/wifi-jellyfish-lantern-with-wled/
This tutorial will show you how to create your own luminescent jellyfish out of iridescent vinyl and NeoPixel LEDs. Easily add endless light patterns with the free, and easy-to-use WLED software, with no coding required. You can even make multiple jellyfish and sync them up over your wifi network.
This is a fairly easy project with no coding and just a little soldering. The end result is out of this world.
This guide will show how to use either our powerful Feather ESP32 V2 or our teeny tiny and affordable QT Py ESP32 Pico get your lights up and running in minutes.
Build two or more jellyfish and sync them together to run simultaneous animations through your swarm. Sounds tricky, but it's two clicks in WLED. This software is free, powerful, and so easy to use that it feels somehow like you're cheating. Get access to around 100 different LED animation patterns that can be paired with dozens of color palettes. WLED gives you speed and intensity control as well. There is no end to the variations of patterns you can create with this amazing software.

Tick tock, it's time for this week's EYE ON NPI - this week we're on time and on budget with the EPSON RX4901CE and RX8901CE Real-Time Clocks. (https://www.digikey.com/en/product-highlight/e/epson/rx4901ce-and-rx8901ce-real-time-clocks). These are two affordable yet ultra-high high precision temperature compensated Real Time Clocks - from EPSON who are well known for their quality crystal offerings (https://www.digikey.com/short/b0t2j2c5). Accurate time-keeping is something folks ask us about a lot - it's a lot harder than most people think! (It's sorta up there with voice recognition and 3D-indoor-spacial-tracking with "things that seem really common but actually are super tough) Most folks are used to alarm clocks that use the power line 60Hz sine wave to keep track of seconds, we've done that for plug-in clocks for almost a century (https://en.wikipedia.org/wiki/Electric_clock) And while the utility's mains frequency does fluctuate with load, its compensated overnight so average out to a near-perfect 60Hz (http://leapsecond.com/pages/mains/).
If you don't have access to that 60Hz calibrated signal, say because you're battery powered, or using a switching supply, you have a few options for externally-validated time keeping. Some folks like the WWVB radio-signal (https://en.wikipedia.org/wiki/WWVB) synchronization modules (https://www.sparkfun.com/products/retired/10060) that receive an atomic-clock-accurate signal from Colorado. Others like to use a GPS module, which will get atomic-clock-accurate signals from spaaaaaaaaaace (https://www.adafruit.com/product/4279), finally of course, if you have Internet connectivity you can get time from NTP (https://www.ntppool.org/en/). All of these require a lot of power, and for GPS you need to have an outside antenna - or at least close to a window. WWVB works best in the middle of the country, but we've always had a little difficulty in a NYC apartment.
If you want low-power or battery-powered time stamping and logging, a real time clock is the way to go. But these chips aren't sync'd to some global standard and they tend to have a lot of drift (https://en.wikipedia.org/wiki/Clock_drift) - seconds a day, which adds up! This is due to the timing crystal having some variation, usually 10 to 20 ppm. 20 parts-per-million is the same as 20 / 1,000,000 * (24 * 60 * 60 seconds/day) = 1.7 s/day variability, or about a minute a month. So it really can add up!
The RTC counter circuitry itself is perfectly accurate, so if we could make sure the crystal was perfect, we'd have no timing issues. To do that, we have to account for the temperature...thus bringing forth the invention of the TCXO Temperature Compensated Xtal Oscillator (https://www5.epsondevice.com/en/products/tcxo/) something that Epson is really good at making! So it's no surprise that they've packaged an RTC chip into one of their crystal-sized enclosures to create a sealed high precision RTC. And the price is really good too! We often see TCXO RTC's for $6-$8, whereas the Epson RX8901CE are $3.25 in quantity and they're also nice and compact, 3x2x2.5mm in size. (https://www.digikey.com/short/mw38mqrz)
Both the Epson RX8901CE I2C version (https://www.digikey.com/short/z4rhvbw0) and the RX8901CE SPI version (https://www.digikey.com/short/hmwj9djc) are in stock right now for immediate shipment from Digi-Key! Order today and you'll get it by tomorrow afternoon - so you can stick to your production schedule with a tip-top RTC that won't waste your time.

As we're redoing one of our testers to work around a part shortage, we're also trying to SMD-ify the whole thing since we use enough of these its worth it for us to make a short run of maybe 50 boards instead of hand soldering.
This tester does a USB enumeration check and so we want a USB Type A connector for the USB host. We've always used the classic THM version of the USB Type A, let's see what's available for SMT at Digi-Key!

This week's EYE ON NPI soars above the rest, it's the Soracom Onyx LTE USB Dongle for IoT Applications (https://www.digikey.com/en/product-highlight/s/soracom/lte-usb-dongle-for-iot-applications), a nicely designed, easy-to-use cellular dongle that you can plug into your Windows or Linux single-board-computer to add cellular connectivity super fast.
Onyx features a Quectel® EG25-G (https://www.digikey.com/en/products/detail/quectel/EG25GGC-128-SGNS/13278144) LTE Cat. 4 module providing global 4G/LTE, 3G, and 2G cellular connectivity in a single device and is optimized specifically for IoT and M2M applications. With a USB port and driver support for Windows and Linux, Onyx (https://www.digikey.com/short/f88n91qt) can be installed on a wide variety of devices to easily add global cellular data connectivity. The device includes built-in antennas for easy installation without extra wires or accessories, and provides two external CRC9 antenna connectors to support custom antenna configurations.
We got this working smoothly on a Windows 10 computer in only 20 minutes - from signing up at Soracom (https://www.soracom.io/getting-started) to registering the SIM (https://developers.soracom.io/en/docs/air/registration/) to installing drivers (https://developers.soracom.io/en/downloads/drivers/) and plugging in the SIM card. We like how it's a cellular modem that shows up just like a network interface but ALSO gives you access to the AT commands in case you want to automate some of the cellular procedures or use the built in protocol managers for ultra-light network usage. (https://www.soracom.io/blog/sending-mqtt-messages-from-celllular-modem-via-at-commands/)
We think the Onyx (https://www.digikey.com/short/f88n91qt) is ideal for folks with single board computers like Raspberry Pi - they have 4 USB ports but no M2 slots. For many uses, the built in Ethernet and WiFi is good for network access, but there's many use cases where you want to have cellular access as LTE or M2M. While there are HATs and accessories to add cellular, this a pretty straight-forward board that won't require updates when there's kernel or GPIO driver dependencies - simply plug it into the USB port for data and power and run the Linux install script that they kindly provide.(https://developers.soracom.io/en/start/soracom/soracom-cli-guide/)
Since Soracom is maker-and-geek friendly, they do better than just providing the hardware and saying "use the PPP modem capability" - for optimized data usage there's documentation on using the native MQTT stack (https://www.soracom.io/blog/sending-mqtt-messages-from-celllular-modem-via-at-commands/) which means even the lightest-weight device can use minimal data while sending sporadic messages - it may also be faster than bringing up a full TCP/IP stack and then tunneling MQTT over it - there's Python example code available too for automated scripting.
The Soracom Onyx (https://www.digikey.com/short/f88n91qt) is available at an excellent price, cheaper than a DIY solution, and it's in stock right now at Digi-Key for immediate shipment, you can also pick up a Soracom SIM for only a few dollars more (https://www.digikey.com/en/products/detail/soracom/4573326590334/16653414). Order today and it'll be shipped in the blink of an eye: you'll be able to add instant cellular connectivity with LTE speeds and GSM/GPRS fallback to your product by tomorrow afternoon!

Music by Bartlebeats https://soundcloud.com/adafruit
This week we're looking to redesign our fancy 'tester brains' that we use for many of our microcontroller boards. We have three flavors of testers, the 'drop and beep' simple ones that use an Arduino / Metro as a base and do basic testing of some I2C sensor, the ones that use a Teensy 3.6 to SWD or ISP program a chip and then do a USB enumeration check, and finally the Raspi ones. We've got plenty of metros, and our stash of Raspi 3's is going fine but we've just about run out of Teensy 3.6's! Since we have a lot of microcontroller boards coming soon we wanted to make sure that we could revise this tester to use an RP2040 - it's definitely fast enough and has enough pins, but we needed to have a bitbang USB host implementation in order to test enumeration and/or communicate over CDC/HID/MSD with TinyUSB. Let's look at what we came up with.
The Great Search - SMD USB Type A Host Connector https://www.digikey.com/short/q5208wrn
As we're redoing one of our testers to work around a part shortage, we're also trying to SMD-ify the whole thing since we use enough of these its worth it for us to make a short run of maybe 50 boards instead of hand soldering. This tester does a USB enumeration check and so we want a USB Type A connector for the USB host. We've always used the classic THM version of the USB Type A, let's see what's available for SMT at Digi-Key!

This week's EYE ON NPI is a breath of fresh air - with the Amphenol Telaire T6793 CO2 Sensor Module (https://www.digikey.com/en/product-highlight/a/amphenol-advanced-sensors/t6793-co2-sensor-module), another great sensor we are happy to highlight from Amphenol Advanced Sensor group (https://blog.adafruit.com/2020/07/23/eye-on-npi-amphenol-ztp-148src1-thermal-sensor-eyeonnpi-digikey-adafruit-amphenolsensors/). This time it's a sensor to detect the concentration of CO2 in the air.
Carbon dioxide, aka CO2, is a gas that is an essential part of the Earth's atmosphere and life in general. However, while essential, it can have negative effects when concentrations exceed certain level. It can impact the entire planet via global warming. But it can also have very local effects, for example on indoor air quality. Elevated levels of CO2 can lead to reduced cognitive ability and other health related concerns. Therefore, monitoring CO2 levels of inside air can be useful as a part of gauging general air quality.
Folks have had CO2 air-quality sensors in buildings and homes for a long time but now they're extremely popular because CO2 levels are correlated with air freshness. Outdoor air is about 400 ppm CO2. Us humans love to breathe in air, extract the O2 and fill rooms with CO2. That means when there's poor ventilation to the outdoors, and lots of humans - the air is going to have higher and higher CO2 concentrations. (https://theconversation.com/how-to-use-ventilation-and-air-filtration-to-prevent-the-spread-of-coronavirus-indoors-143732) We consider under 1000 ppm to be 'good' but really we want to keep it under 600 ppm if we can since that has been shown to reduce transmission of airborne disease. (https://onlinelibrary.wiley.com/doi/full/10.1111/ina.12639)
There are two categories of CO2 sensors we see. One is the 'effective CO2' measurement, which is really a VOC sensor using doped MOX variable resistance sensors, and the other are 'true CO2' sensors which use NDIR. For example, the ENS160 breakout (https://www.adafruit.com/product/5606) we recently started stocking is a MOX sensor that will provide measurements of overall air quality based on volatile gases. It can also use this to approximate the CO2 concentration. But note it isn't actually measuring CO2! While this is fine for low cost or basic AQI measurements, it isn't a calibrated or reliable way to measure CO2.
Instead, the right thing to do is use an NDIR sensor (https://en.wikipedia.org/wiki/Nondispersive_infrared_sensor) like the T6793 CO2 Sensor Module (https://www.digikey.com/short/h4278vt7), which is a 'true' CO2 sensor that will tell you the CO2 PPM (parts-per-million) composition of ambient air. That means it's a lot bigger and more expensive than eCO2 sensors, but it is the real thing. Perfect for environmental sensing, scientific experiments, air quality and ventilation studies, and more.
The Amphenol T6793 CO2 Sensor Module (https://www.digikey.com/short/h4278vt7) is a true NDIR CO2 sensor, with self-recalibration if used outside where it will be exposed to 400ppm CO2 signal at least once a week, and comes in two versions, one with 2Kppm and one with 5Kppm maximums. It's highly stable, and accurate with +-45ppm + 3% of reading accuracy and continuous 5 second readings.
One thing we really liked about this sensor is that it has multiple output modes, no matter what your system integration requires. The T6793 comes with a wide selection: 100KHz I2C, UART, RS485 and even PWM output! The module comes with a 6-pin 0.1" / 2.54mm pitch header so it can be swapped out of a larger system after a few years or if the sensor gets contaminated. The PWM pulse rates and I2C registers are documented in the app note (https://www.amphenol-sensors.com/en/telaire/co2/525-co2-sensor-modules/3399-t6713) and there is some some Arduino code available on GitHub for reference. (https://github.com/AmphenolAdvancedSensors/Evaluation_Kits/tree/AAS_AQS_UNO_RH_CO2)
If you want high-quality, reliable, and accurate CO2 sensing with a true NDIR sensor - you are in luck because the Amphenol T6793 CO2 Sensor Module (https://www.digikey.com/short/h4278vt7) is in stock right now at Digi-Key for immediate shipment! Order today and you can have this fancy golden sensor ready to use by tomorrow afternoon.

For a small STEMMA board we designed and prototyped, we'd like to have it emit powerful IR pulses to turn on/off remote control devices. We've used through-hole IR LEDs before, they are interesting in that they are usually pulsed at 100mA-1A of current (not your regular 20mA)!
However, for this design to stay easy-to-use, we need to source SMT LEDs. So let's find a bright (80mW/sr or greater), infrared (940nm wavelength), side emitting LED.

Music by Bartlebeats https://soundcloud.com/adafruit
At the desk this week, we've got a fevah and the only cure is testing out the proto picowbell we fabbed this week. This board got a little distracted over the few months as parts started to come in, but we improved it in the meantime - now it has both a reset button and QT/Qwiic port & a nice silkscreen. let's try it out with the new CircuitPython 8.0.0b2 release that adds Pico W WiFi support! We also have two stemma samples we put together: one is an IR blaster, and the other is a Si5351 QTification.
The Great Search - Bright Side-emitting Infrared SMT LED https://www.digikey.com/short/5v5zvjvv
For a small STEMMA board we designed and prototyped, we'd like to have it emit powerful IR pulses to turn on/off remote control devices. We've used through-hole IR LEDs before, they are interesting in that they are usually pulsed at 100mA-1A of current (not your regular 20mA)! However, for this design to stay easy-to-use we need to source SMT LEDs. So let's find a bright (80mW/sr or greater), infrared (940nm wavelength), side emitting LED.

We're doing a big refresh on our TFT display breakouts to add EYESPI connectors, which means we ought to also make a EYESPI Raspberry Pi accessory - something that will make it easy to solderlessly connect e-Ink or TFT or other SPI-based displays.
We're looking for a slim 2x20 header, ideally one that allows 'pass through' behavior, which means SMT is best. Let's see what is available over on Digi-Key that will make this prototype ready-to-rock.

Desk of Ladyada - TFT's Galore!
This week at Ladyada's desk, we focused on a big TFT revision sweep - we have a new TFT supplier that can get us back to the prices we used to get. In addition to the existing TFTs we use, we also got a bunch of samples of new displays such as ones with capacitive touch. While we're at it, we're also redesigning our TFT breakouts to have EYESPI connectors, which will make testing / usage a lot easier. Let's look at what TFT samples we got and chat about different TFT types and protocols.

This week's EYE ON NPI is a cut above, it's the Scotch Precision Scissors from 3M (https://www.digikey.com/short/p108w7bd) - a collection of a dozen or so different scissor models all stocked and available from Digi-Key.
Normally we tend to cover electronics tools and parts on EYE ON NPI - chips, modules, antennas, components...so why are we talking about scissors? Because nothing ruins your day like BAD SCISSORS! You know what we're talking about, not sharp enough so that stuff has a raggedy edge. Or easily nicked so cutting isn't smooth and you get that annoying clicking effect as you're trying to get an elegant curve going?
The solution is easy! Add a pair or two of Scotch Precision Scissors (https://www.digikey.com/en/product-highlight/3/3m/scotch-precision-scissors) to your cart so next time you check out you get a gift for yourself, a fancy new pair that will bring joy.
We use our nice pair of scissors all the time to cut open Digi-Key sealed bags, trim foam tape, cut conductive copper sheets and labels. And if you have a partner who has their own fancy pair for cutting fabric you will no longer end up making them sad when you borrow their pair (https://www.ctpub.com/blog/by-the-yard-cutting-paper-with-fabric-scissors-explained/) - or if you did already muss up their favorite set, you can now bribe them back into your good favor with a scissor-based peacekeeping gift.
There's about 10 different types available, from kid's crafting scissors to multi-purpose to precision types (https://www.digikey.com/en/product-highlight/3/3m/scotch-precision-scissors) so be sure to peek through all the versions. 3M Scotch Precision Scissors are in stock right now for immediate shipment from Digi-Key (https://www.digikey.com/short/p108w7bd) - order today and you'll have them literally in your hands by tomorrow morning.
While you're waiting for that package to arrive, check out 3M's cool 'science at home' series (https://www.3m.com/3M/en_US/gives-us/education/science-at-home/science-experiments-for-kids/). They're a great set of easy-to-build projects that use common crafting materials that you can do together with kids to pique their STEM curiosity.

This week's EYE ON NPI has an EYE TO THE SKY, it's a new MAX-M10 series of ultra-low-power GPS modules from u-blox (https://www.digikey.com/en/product-highlight/u/u-blox/max-m10-series). u-blox is famous for their high quality GPS modules, they've been making them for about 20 years and they've never stopped iterating on their trusted designs. This new generation of modules, the MAX-M10 series, comes in two flavors for cost vs tracking-sensitivity optimization.
The MAX-M10 modules are the same footprint, and both support the four active or soon-to-be-active GNSS constellations: GPS (USA-launched satellite system), GLONASS (Russia), Galileo (Europe) and BeiDou (China)
The MAX-M10 is available in S series (https://www.digikey.com/short/r5j974z0) and M series varieties (https://www.digikey.com/short/zp5v73zm).
The MAX-M10S-00B S series has a temperature compensated oscillator (https://en.wikipedia.org/wiki/Crystal_oscillator#Temperature) a.k.a TCXO for the frequency tuning, so you'll get better sensitivity and tracking: -167dBm sensitivity compared to the M series' -164dBm, but at higher current draw and pricing.
The MAX-M10M-00B M series has a regular crystal a.k.a XTAL, for lower cost and power usage, but will take longer to get initial fix and won't have as good sensitivity. Also, the M series can run 1.8-5.5V, where as the S series is 1.8-3.3V max and has a SAW filter (https://en.wikipedia.org/wiki/Filter_(signal_processing)#SAW_filters) and LNA (https://en.wikipedia.org/wiki/Low-noise_amplifier).
Both modules have UART and I2C support, which is great news because so many microcomputers and 'controllers do not have lots of spare UARTs. I2C has a built in buffer and you can query the current size and then read bytes out of it. Do note that I2C has clock stretching so you will need to either slow down the baud rate or verify your controller can handle the stretching. For UART mode, default baud rate is 9600 but can be configured higher.
Unlike some basic all-in-one modules, the MAX M10s require an external antenna. You can use either passive (https://www.adafruit.com/product/2461) or active antennas (https://www.adafruit.com/product/960), active antenna only needs a few passive components. If you want to really have a fancy setup, you can enable an antenna supervisor circuit which can tell you if the antenna is connected, shorted, or even open. (https://www.u-blox.com/sites/default/files/MAX-M10S_IntegrationManual_UBX-20053088.pdf)
The recent GPS modules from u-blox also support their native IoT cloud asset tracking system called CloudLocate (https://www.u-blox.com/en/product/cloudlocate) also known as ThingStream (https://www.u-blox.com/en/product/thingstream) which seems to do a very cool thing where you don't actually need to get a fix or download the ephermeris data, you can stream timing measurement deltas immediately and the calculation of GPS coordinates is done by a computer that has almanac data all loaded up. Of course this works only if you have a LoRa/Cell/WiFi connection already but for asset tracking it's a cute idea!
Wanna upgrade your GNSS product to the very latest and greatest u-blox 10th generation series today? You can because the MAX-M10S-00B is in stock right now at Digi-Key for immediate shipment! (https://www.digikey.com/short/1rdqtp9j)
And while you're waiting for your next-day shipment to burst out the warehouse doors and make its way into your arms, be sure to sign up for the free webinar on October 12th on Accelerating Your Wireless Solution Development ( https://dky.bz/3E0mPOI) which will use the u-blox XPLR-IOT-1 dev kit (https://www.digikey.com/short/051jv5r0) for quick LTE / NB-IOT / WiFi / GNSS development.
This week @adafruit we’re making a CO2 sensing canary with Adafruit IO. Prototyping glowy projects using new LED noodles. Timelapse this week features a potion bottle designed by Ars Moriendi printed in glow-in-the-dark filament.

Social media is abuzz lately over the prospect of cheating in tournament strategy games. Is it happening? How is that possible with officials watching? Could there be a hidden receiver somewhere? What can be done to rectify this? These are probing questions!
We’ll get to the bottom of this by making a simple one-way hidden communicator using Adafruit parts and the Adafruit IO service. Not for actual cheating of course, that would be asinine…in brief, a stain on the sport…but to record for posterior whether this sort of backdoor intrusion is even plausible or just an internet myth.

A few months ago, we were forced to find a replacement for the FAN5333 constant-current LED driver (https://blog.adafruit.com/2022/08/02/the-great-search-white-led-strand-backlight-constant-current-driver-fan5333-replacement-thegreatsearch-digikey-adafruit/). Well, now we have to find a replacement for its sister - the fixed voltage boost converter FAN5331 (https://www.digikey.com/short/bzrmmh08) which has gone "end of life" on us.
A real tragedy: we absolutely loved this simple SOT-23-5 chip which could take 3-5VDC in and give up to 20V out with a built in 1A switch, only a small inductor and diode needed! We use this for many of our OLED displays and other devices that need a bias voltage of 12-18VDC. Let's see if we can locate a pin-compatible, functionally-similar equivalent that's in stock.

Desk of Ladyada - time for some newNEWnEw designs!
We designed a bunch of boards this week, let's take a look at what got spun up: With Si5351's back in stock and available, we have QTified the breakout board for this popular clock generator.
We're also QTifying the ADT7410 and EYESPIifying the 1.8" and 1.54" TFTs. The TPS61040 is a fair replacement for the FAN5333, so there's a mini breakout for that The PiCowbell proto has been patiently awaiting me to look up the default I2C pins for the Pico in Arduino so we could make a rev B with stemma QT port in addition to an SMT right-angle switch Finally, a customer with an IR LED question prompted us to design a breakout board that makes it easy to add high-powered IR LEDs without soldering.

A few months ago we were forced to find a replacement for the FAN5333 constant-current LED driver (https://blog.adafruit.com/2022/08/02/the-great-search-white-led-strand-backlight-constant-current-driver-fan5333-replacement-thegreatsearch-digikey-adafruit/) - well, now we have to find a replacement for it's sister - the fixed voltage boost converter FAN5331 (https://www.digikey.com/short/bzrmmh08) which has gone "end of life" on us.

For our TCA9548 QT breakout, we're going to allow switching the QT power and signal between 3 and 5V, so it could be used for level shifting. This means the switch itself will be carrying power - we're not using a separate FET-based switch.
It's reasonable for us to expect about 500mA total current among all of the 'client' boards, and we have a 500mA regulator on board to manage that.
However, that switch has to be spec'd for the voltages and currents we're expecting to pass through it! It's very easy to glide over contact specs for switches if you're used to signal-only usage. Let's find a vertical switch that can handle 5V and up to 500mA total.

Desk of Ladyada - Proto-buildin' Weekend
This weekend we put together a bunch of prototypes so that we can order PCBs! First up, the PB86 breakouts we designed a few weekends ago came, and they work great, with side-by-side stack-ability. Then, we're redesigning the microlipo charger to have a current-selector switch - a few mistakes were made but they were easy to sort out and get the board tested. Finally, the TCA9548 QT breakout board is also good to go, with a voltage selector switch and all ports working. We're designing the tester for it now and are reminded that it's always good to add test points for making testing fast and easy! The Great Search - Current-carrying Slide Switch https://www.digikey.com/short/jdwr22pb
For our TCA9548 QT breakout, we're going to allow switching the QT power and signal between 3 and 5V, so it could be used for level shifting. This means the switch itself will be carrying power - we're not using a separate FET-based switch. It's reasonable for us to expect about 500mA total current among all of the 'client' boards, and we have a 500mA regulator on board to manage that. However, that switch has to be spec'd for the voltages and currents we're expecting to pass through it! It's very easy to glide over contact specs for switches if you're used to signal-only usage, let's find a vertical switch that can handle 5V and up to 500mA total.

This week's EYE ON NPI is a self-starting go-getter, it's the EDK350/EDK350U Developer Kits from EnOcean (https://www.digikey.com/en/product-highlight/e/enocean/edk350-and-edk350u-developer-kits) - containing everything you need to get started with energy-harvesting / self-powered sensors. These kits are a great way to explore and understand the EnOcean series of solar & mechanical energy-harvesting switches and sensors.
As engineers, we're often tasked with 'smartening up' existing structures: whether that's machinery, agriculture, buildings, cars, appliances, etc. The last few decades have given us ultra-cheap sensors and radios - which means we are able to gather data from a wide area and store it centrally, the Internet of Things! (https://en.wikipedia.org/wiki/Internet_of_things) That means just about every project and product you will work on is going to have sensors, data storage and wireless - but with great technology comes great complexity: you now have to worry about shuffling that sensor data around, and nothing eats up batteries like constantly having to wake up and transmit radio data.
In fact, a lot of the really tough engineering with sensor networks is not in picking the radio or sensor but in how to keep the battery lasting as long as possible. Particularly since folks like products with small, rechargeable batteries - but they don't like having to constantly plug them in. Moreover it's really hard to let people know when something needs to be recharged - there's the problem of "well we need power to blink an LED or sound a buzzer which will drain the power even faster - but if we blink or buzz too rarely it may not be caught in time to change out the battery before it dies". Also known as the 'smoke detector issue' - Americans kind of solved this by starting a campaign to check smoke detector batteries on every daylight savings change (https://www.nfpa.org/Public-Education/Staying-safe/Safety-equipment/Smoke-alarms/Changing-clocks-and-batteries). Great for individual households with maybe 3 or 4 smoke detectors - not great if you have dozens or hundreds of light switches or soil moisture sensors.
EnOcean solved this in a typically engineer-y fashion: what if, instead of having batteries which add cost, maintenance and life-cycle management...we just didn't? Instead, their devices use energy harvesting (https://www.youtube.com/watch?v=zJIlG-KbFzE), which means that - in theory - there is no installation or maintenance costs at all. Once installed, it will forever sip power from motion or ambient light until there's enough power for a transmission. EnOcean even has their own low power 900/868MHz radio modules with integrated 8051's that are specifically designed for quick startup, sensing, transmission and power down.
The most famous is their ECO200 mechanical energy harvesting switch, (https://www.enocean.com/en/product/eco-200/) which also made it into the Philips Hue wireless lighting system (https://meethue.co/hacks/convert-hue-tap-to-a-light-switch/), a great fit since the whole system is wireless, and there's a natural inclination to associate pressing a button with changing the light settings. In addition to the classic mechanically-powered switches, there's also a series of micro-solar powered sensors, (https://www.enocean.com/en/product-category/self-powered-sensors/) good when you need to have a slow but continuous measurement of environment. Tuck these near a fluorescent light fixture and you could sip enough power to send data once every few hours or per day - no wiring or installation required. (https://www.youtube.com/watch?v=PkynD9FOVxY)
If this technology is something you want to look into integrating, you can get started with the EnOcean EDK350/EDK350U Developer Kit, (https://www.digikey.com/short/77dn99q8) a chocolate box assortment containing one of each of EnOcean's sensors and switches. You get radios, USB sticks, mechanical and solar harvesters! Available in both 900MHz for Americans, or 868MHz for Europe / Asia. And both kits are in stock right now for immediate shipment from Digi-Key! (https://www.digikey.com/short/77dn99q8) Order today and you will be energy harvesting by tomorrow afternoon.

We use lots of Schottky diodes in our products for power supply circuits. Traditionally we've used the On Semi MBR120VLSFT1G (https://www.digikey.com/short/rd25c3rt) which is 20V forward, 1A current, SOD-123 package, and a slim 340mV forward drop at 1A. You'll be shocked (or is it...Schottk'd?) to hear that it's unobtanium, with a 75 week lead time.
We looked at some other parts in the MBR120 base product number family (https://www.digikey.com/short/vjr347bp) but they're also out of stock! However, we will not be deterred - let's use our Great Search Skills to find a good drop-in replacement diode at Digi-Key with matching-or-better specifications!

Desk of Ladyada - Use ANY font in EagleCAD with Pinguin
We've been doing a ton of revisions lately and as we're re-spinning boards we had a bit of an itch to make some pretty silkscreens. Normally the way nice silks are done at adafruit is we ask PaintYourDragon to do a custom silkscreen after the PCB is laid out. This of course results in the gorgeous designs for the MacroPad and Monster M4sk...but for lil breakouts it's a ton of work to export/design/re-import the top and bottom silks. And it's also hard to tweak the design. So we asked 'drag0n to come up with some automated way to change the font from a servicable-vector-y font. A week later and Pinguin is born, a python script that will swap any font for you, automagically, and even do a pretty darn good job of keeping the size the same. Let's check it out!

This week's EYE ON NPI has great vibes, it's ST Micro's AIS25BA 3-Axis Accelerometer (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/ais25ba-3-axis-accelerometer) a unique take on the classic tripe-axis motion sensor where data is streamed out with a TDM interface rather than I2C or SPI!
We've never seen this kind of sensor but the idea behind its use case is kinda cool and is a great demonstration of using sensor fusion to cancel out or extract data from two 'directions'.
Usually accelerometers we've covered on NPI before are used for tilt or motion sensing, detecting if something is falling or was struck. Another good use for this common sensor is vibration detection. You need very fast sensor reading but any vibration can be detected and sensed as motion and then integrated for displacement. That's pretty much what a microphone (https://en.wikipedia.org/wiki/Microphone) does as well, right? It takes vibrations in the air, then the displacement is converted to a capacitive measurement via MEMS (https://www.digikey.com/short/tt7qnddr) or current/voltage measurement via electret (https://www.digikey.com/short/9vdczd9n).
So, what if in addition to measuring the air movement with the microphone, we also got to measure the vibration of a surface with an accelerometer? Dense surfaces will be better at low frequency measurements, and the microphone element will be better at high frequency. With a little filter work, we can combine these two data streams so that we get clear audio without the motion or air noise that often adds crackling, or overwhelms the analog front end. (https://www.st.com/resource/en/flyer/fllis25ba0218_lr.pdf)
ST Micro's AIS25BA 3-Axis Accelerometer (https://www.digikey.com/short/3zrr4c8b) is the automotive-qualified version of the LIS25BA (https://www.digikey.com/short/c9bt59c0) but both function basically the same so choose whichever is best for your application. In both sensors, the configuration and test is still done over I2C - setting gains, offset, self-test, etc. Then data is streamed over a TDM audio-interface so it can be quickly funneled into a DSP or microcomputer that performs the high/low-pass filtering and merging. As demo'd by an ST engineer (https://www.youtube.com/watch?v=bi4NenlnR-k), the sound quality is greatly improved, kinda like a reverse-noise-cancelling-headphone.
Particularly as so many more devices like cars are becoming voice-controlled to allow for advanced uses, and avoid mechanical components that can wear out or get dirty, having good clean audio input (https://www.st.com/resource/en/user_manual/um2824-getting-started-with-the-stm32cube-function-pack-for-acoustic-echo-cancellation-stmicroelectronics.pdf) is key to having a UX that is great versus one that is annoying to use. There's even a driver for the I2C side of things over on GitHub to get you started quickly. (https://github.com/STMicroelectronics/ais25ba-pid.git)
Best of all, STMicroelectronics' AIS25BA 3-Axis Accelerometer (https://www.digikey.com/short/3zrr4c8b) is in stock now at Digi-Key for immediate shipment! Order today and your sensors will be shipped immediately so you can be noise-cancelling like a pro by tomorrow morning.

We think FRAM chips are the most underrated storage chips engineers can use - they're excellent for datalogging! They also solve the biggest frustration when people try to stream data to EEPROM, SD card or Flash memory: erase times for blocks can stretch to hundreds of milliseconds, and you often need to write a whole block at a time. SRAM is nice but will erase itself when power is lost. If you need to burst-write data to a reliable storage medium that is OK with having power cut - FRAM is great. We have a few FRAM breakouts (https://www.adafruit.com/?q=fram&sort=BestMatch) but we've found some chips are discontinued/obsolete (https://www.digikey.com/short/wc94tmd2). Let's see what options we have for replacements - a good lesson in how to read and understand PCNs.

Last time we checked in on the PicoW CircuitPy progress, we saw the onboard LED blinking - basically proving that the SPI transport and firmware upload was working. This round, we're starting to see the beginnings of integration support, with the ability to read the MAC address, scan for accessible SSIDs, and connect to get an IP address! there's still a lot more to do, like DNS support, LWIP integration and a TLS stack, so it's great to see progress 🥧🐮

we're trying to revive the old EZ-Link Bluefruit design from many years ago - originally done with a CSR chipset that became very hard for us to get. ESP32 is a lot easier and the original chip has BT classic support - required for BT SPP which is what we're using. This test uses the Arduino IDE, we are uploading code from the IDE 'transparently' to the COM port which the operating system makes when you pair to a BT SPP profile device. Since we pass the baud rate and control lines, we're able to auto-reset and transmit data as if it were connected with a USB cable! here, we're uploading a NeoPixel test sketch and it seems to be working

We got a whole mess of interesting mechanical samples - from fancy-pants breadboards to encoders and joysticks. We're also doing a lil bit of refactoring of hardware designs, since it was time to re-order 1.8" TFT breakout PCBs we decided to give up a glow-up to add an EYESPI port. Also we've started the tester for the ESP32 ItsyBitsy.

This week's EYE ON NPI is all about us giving you the skinny on an ultra-thin way to add wireless charging to your next design - it's TDK's WCT Ultrathin Pattern Coil for Wireless Charging! (https://www.digikey.com/en/product-highlight/t/tdk/ultrathin-pattern-coil-for-wireless-charging) This coil is less than a mm thick, and is designed to work with any and all Qi charging chips so you can add wireless charging without having to also design and manufacture a charging plate.
If you have a modern smart phone, you may have noticed that it comes with built in wireless charging capability called 'Qi charging.' Qi (http://en.wikipedia.org/wiki/Qi_%28inductive_power_standard%29) is a trademark name for a thin and smart inductive charging system. Many large gadget companies have standardized on Qi, which means it's easy to find a charging dish - there's even charging plates in many cafe's or waiting rooms.
Wireless charging has a few really good benefits (and one or two downsides). Most importantly, it's extremely convenient. Folks are more likely to forgive a design with a smaller battery / battery-life if charging can be done as easily as placing it on a table overnight. Secondly, it allows for a more water-proof design - handy for things like watches and headphones that may use BLE for data transfer. Normally you'd still need to plug in to charge, but now there's no need at all for a USB port! In addition, you get a lot less wear on the power connector, since every insertion (https://en.wikipedia.org/wiki/USB_hardware#Durability) adds the chance that the connector will get something jammed inside, or a contact worn out, or strain on the connector mechanics that lifts it off the PCB.
Downsides of Wireless Charging is that, yes it adds some cost because you need a Qi chip and the matching antenna, and they both take up space in the build as well. Qi is also traditionally 5W which is good, but relies on having a good inductive link between the base and the device. Before Qi, you also had to design both sides of the link, (https://www.adafruit.com/product/1407) which was often not worth the extra effort when time-to-market is so important. Now with Qi you can use any off-the-shelf charging plate or transmitter module (https://www.digikey.com/en/products/detail/adafruit-industries-llc/2162/6827104). And this antenna is so thin you can easily fit it between your PCB assembly and the plastic enclosure.
You might be surprised how easy it is to add Qi standard wireless charging these days, and with the TDK's WCT Ultrathin Pattern Coil (https://www.digikey.com/short/z1r3jtrh) you don't have to make a ton of room. Add in a Qi wireless charging receiver chip (https://www.digikey.com/short/db3rp415) and you can have a magical user experience with no cables. Best of all, the TDK pattern coil (https://www.digikey.com/short/z1r3jtrh) is in stock right now at Digi-Key for immediate shipment - order today and you can be charging by tomorrow afternoon!

This week's great search is a two-fer as we look for small classic ESP32 modules! Traditionally we've used the big ESP32-WROOM https://www.digikey.com/short/fftf34vt such as seen in the HUZZAH Feather https://www.adafruit.com/product/3405 , OR we've used the u-blox NINA W10 https://www.digikey.com/short/n2d0cwn5 such as on the Airlift Bitsy https://www.adafruit.com/product/4363.
We just got notice that the NINA is Last Time Buy, so it's time to find a replacement for AirLift. Likewise, we designed the EZ-Link with ESP32 Pico Modules https://www.digikey.com/short/m853jv84 but perhaps it's a little overkill since we don't need so much Flash and PSRAM? Let's use Digi-Key plus the Espressif part selector https://products.espressif.com/ to find some good alternatives.

This week on the Desk of Ladyada it's been a prototyping bonanza with a lot of work on testers and new designs. First up we wanted to wrap the tester for the CH9102F but found that part of our test is to check the DTR/DTS RTS/CTS pains and the Linux kernel driver for the CH343 family did not have CTS working! Thankfully we found an out-of-tree driver https://github.com/SoldierJazz/ch343ser_linux.git that does the job and allows us to perform the test procedure. Next up we put together prototypes for the EZ-Link ESP32 and tried out some code, like the CH9102F, there were some flow control issues to work out in the BT SPP stack but it works! Finally we test out the latest CircuitPython PicoW WiFi stack work, where there is slow-n-steady progress.
The Great Search - ESP32 modules in all Shapes and Sizes! https://www.digikey.com/short/dpd0wdnq
This week's great search is a two-fer as we look for small classic ESP32 modules! Traditionally we've used the big ESP32-WROOM https://www.digikey.com/short/fftf34vt such as seen in the HUZZAH Feather https://www.adafruit.com/product/3405 , OR we've used the u-blox NINA W10 https://www.digikey.com/short/n2d0cwn5 such as on the Airlift Bitsy https://www.adafruit.com/product/4363 . We just got notice that the NINA is Last Time Buy, so it's time to find a replacement for AirLift. Likewise, we designed the EZ-Link with ESP32 Pico Modules https://www.digikey.com/short/m853jv84 but perhaps it's a little overkill since we don't need so much Flash and PSRAM? Let's use Digi-Key plus the Espressif part selector https://products.espressif.com/ to find some good alternatives.

Part of living through a Chip Shortage https://www.youtube.com/c/adafruit/search?query=chip%20shortage is dealing when different package versions come up. For example, the popular INA219 breakout we make https://www.adafruit.com/product/904 has been traditionally used by us in a SOT-23-8 package...but its AWOL so what to do? Easy! we'll respin the board for allowing an SOIC version of the chip instead! this prototype has footprint pads for both, but all other connections and jumpers are in the same location so our testing procedure and usage should be drop-in equivalent.

This week's EYE ON NPI is 'curing' your thermal interlock woes with a huge collection of different thermal monitoring sensors from KEMET (https://www.digikey.com/en/product-highlight/k/kemet/trs-series-and-ohd-series-thermal-sensors). These thermal relays are reliable and easy to spec and use in your design for either Make or Break on temperature-crossing. Use them as a simple temperature control system, or as a last-line-of-defense interlock.
KEMET’s TRS and OHD thermal sensors (https://www.digikey.com/en/product-highlight/k/kemet/trs-series-and-ohd-series-thermal-sensors) are simple and reliable sensors that work using the Curie point property (https://en.wikipedia.org/wiki/Curie_temperature) - which we learned about in high school and had totally forgotten about until now. Basically, there are some magnetic materials where, when the temperature hits a certain point, the crystalline alignment of the material breaks down completely and the material become a-magnetic.
We can take advantage of the Curie Point property to create a special kind of reed switch (https://www.digikey.com/en/products/filter/magnetic-reed-switches/193). Normally reed switches are activated by an external magnetic field that is brought closer to the switch (https://www.youtube.com/watch?v=H85MyhbcC0U) which pulls two two ferrous elements inside together to make contact. With these thermal sensors, the magnet is wrapped on the outside with interleaved Thermorite (https://www.digikey.my/en/articles/kemet-thermorite-temperature-sensor-built-in-on-off-reed-switch) tuned-Curie-point rings that either channel or break the magnetic field. So, say normally the reed switch inside is connected because there's a magnetic ring of Thermorite around it. When the temperature rises, and hits the Curie Point, the magnetic ring suddenly turns amagnetic, and the metal springs are no longer attracted to each other, opening the connection. A similar technique occurs for the Make type but with a clever interleaved Thermorite-sandwich instead.
By tweaking the Thermorite contents, the switches can be tuned to different temperature ratings with 15 degree C binning (https://www.digikey.com/en/product-highlight/k/kemet/trs-series-and-ohd-series-thermal-sensors). KEMET also makes them in a variety of shapes with and without leads, and encased with UL listing.
You can get started by picking up a KEMET Thermal Sensor Engineering Kit (https://www.digikey.com/short/3tnpf2bw) to get a collection of various Make and Break sensors. Whatever version you need, Digi-Key has a wide range of KEMET’s TRS and OHD thermal sensors (https://www.digikey.com/en/product-highlight/k/kemet/trs-series-and-ohd-series-thermal-sensors) in stock for immediate delivery. Order today and you'll be Curie'ing by tomorrow afternoon.

This week we're wrapping up the DS4420 breakout we designed 2 years ago, because we finally found some chips! But as we got this board up and working, we thought it would be nice to have a stereo version of this board. Let's look for an in-stock, stereo analog, line-level/headphone audio amplifier with I2C audio volume control. We've seen a lot of nice improvements to the Digi-Key search boxes and we'll feature some new search features we used to help find this part!

This firmware UF2 for the Raspberry Pi Pico W LOOKS simple enough... on boot it blinks the onboard LED 3 times and then boots into CircuitPython 8. but, looks can be deceiving! the LED on the Pico W is not connected to a GPIO on the RP2040... it's connected to a GPIO on the WiFi/BLE module! that blinking means that we're able to load firmware and communicate with the module in the CircuitPython firmware, an important first step before we implement the rest of the wireless stack. soon, we'll have CircuitPython and the hundreds of libraries and IoT examples ready to run on the Pico W, we can't wait to show you more as we get ready for folks to test it out :)

Wow we did a lil cleanout of some ~2 year old prototypes and found a bunch that were either forgotten or could not be made and now that there's a slight loosening of the parts shortage, we're able to wrap these up and get them into the shop: the ENS160 CO2 sensor, QT hub, QT level shifter, DS4420 are among the many we wrapped this week and ordered PCBs. We also got a big pile of prototype PCBs that will turn into future boards, let's take a look at some! We might also get to some nice wire-snap samples that arrived this week.

This week's EYE ON NPI is a throwback to the 8-bit era, with a new spin on the classic AVR microcontrollers we've loved for decades: it's Microchip's AVR® DD Family of Microcontrollers (https://www.digikey.com/en/product-highlight/m/microchip-technology/avr-dd-family-of-microcontrollers), a powerful update to the powerful and low-power AVR RISC core that came from Atmel. While many folks may be moving to Cortex M0 or RISC-V chipsets to get 32-bit performance, there's still a lot of demand and use for 8-bit microcontrollers. Cost, simplicity, reliability, code-size, and power usage can all be better on 8-bit. If you're only on a 32-bit micro because of peripherals that tend to come with the fancier chips, you might be surprised by what the AVR DD family has to offer.
For example, these chips have external interrupts on (just about all) the GPIO pins. There's four 16-bit timers plus one 12-bit (that's five total timers!), SPI & I2C, two UARTs, a 10-bit DAC, and 12-bit input ADC that's muxed to almost every pin. In particular, the high-bit ADC and DAC are a little unusual to see in an 8-bit platform.

There's also some funky MCP-specific peripherals that can help reduce BOM cost. For example, CCL/LUT is a peripheral that allows you to make custom logic-lookup-tables for making simple - but very very fast - multi-input logic gates that can use interrupts or peripherals as input. (http://ww1.microchip.com/downloads/en/AppNotes/TB3218-Getting-Started-with-CCL-90003218A.pdf) For example, you can make a SR latch, logic gate, or Manchester encoder - you can think of it as like a 'micro' PIO or CPLD.
MVIO is a new capability that we haven't seen before, where an IO port can run at a different logic level - either higher or lower than the VCC power. This allows easy bi-directional interfacing of SPI/I2C/GPIO to 3V logic from 5V, or vice versa, without the use of level shifting! (http://ww1.microchip.com/downloads/en/Appnotes/GettingStarted-MVIO-AVRDB-DS90003287A.pdf) Perfect if you want to run this main core at 5V for speed and signal strength, but have some 3V sensors to interface to, or run the core at 1.8V for power and IO but have a 3.4V LED you want to light up.
Clock rate is up to 24 MHz, can be powered from 1.8 to 5.5V - it's exceedingly rare to find 5V ARM chips - and have FLASH, SRAM, EEPROM and NVM. EEPROM in particular is not common on ARM chips, and some don't even have built in Flash. So think of this as a compact li'l chip with pretty much everything you need to get a product out the door, with a range of memory sizes and physical packages from QFN to DIP! (http://ww1.microchip.com/downloads/en/DeviceDoc/AVR-DD-Product-Brief-DS40002215A.pdf) It's nice to see Microchip is still innovating the AVR line, to make better 8-bit micros that power the electronics around us.
For programming, of course you can use MPLAB IDE but we like Arduino compatibility and SpenceKonde's DxCore (https://github.com/SpenceKonde/DxCore) looks like it's adding or added AVR DD support, so you can quickly get going with compiling code and using the basic peripherals in just a few minutes!
Best of all, the AVR DD family of parts (https://www.digikey.com/short/m4qb8wf8) are totally in stock at Digi-Key right now for immediate shipment. There's SOIC, SSOP and QFN packages with up to 64KB flash / 8 KB RAM, all for about $1.50 in individuals, $1 in qty. If you're looking for an alternative to the ATmega328, this is a nice step up. We recommend getting started with the AVR DD Curiosity Nano board which is breadboard compatible and has everything needed to get started. (https://www.digikey.com/short/10n70tmc) Order today and you can be MVIOing towards your next AVR 8-bit based product by tomorrow afternoon!

We've carried the CCS811 as a breakout board (https://www.digikey.com/short/87r2tq3f) for a while now, but the sensor itself is now discontinued! (https://www.digikey.com/short/0n58n301) We checked out the official replacement, ENS160 (https://www.digikey.com/short/db4fqrv3) but it's not in stock right now. We stock a few other gas sensors, but it's a good time for us to take a peek at what is new and available in this area. We've seen a big increase in MOX-based VOC sensors, sometimes with additional add-ins like temperature or humidity.

This weekend was super bright and sunny, which made it a great time to test out a whole mess of light sensors. We got in our samples from last weeks' chat, the ultra-low-cost LTR-329 (https://www.digikey.com/short/jvn94ncp). This sensor would make a good digital-only alternative to the ALS-PT19 (https://www.digikey.com/short/n550jdwp) 'analog' light sensor. And 'while we were there' we also picked up the LTR-303 (https://www.digikey.com/short/pmr33330), which is very similar to the 329 but has an IRQ output. Thankfully both use similar packages to the GUVx and LTR-390, respectively, which means we were able to recycle existing prototype PCBs to test em out. And then we also wrapped up a driver for the GUVB-C31SM UV sensor (https://www.digikey.com/short/tfzc9h7t) and tested it outside. The UVI calculation seems off, the datasheet is a lil 'so-so' on details but we are getting data so it's mostly just a matter of figuring out how to do the data scaling.

This week's EYE ON NPI merges Creativity with Reality - we're showcasing the bumper crop of Creality 3D printers now available from Digi-Key! (https://www.digikey.com/en/product-highlight/c/creality/ender-3-s1-pro-3d-printer)
We've covered lots of tools (https://blog.adafruit.com/2022/07/13/eye-on-npi-jonard-tools-rapid-microduct-deburring-tool-eyeonnpi-3dprinting-jonardtools-digikey-adafruit/), soldering irons (https://blog.adafruit.com/2021/01/26/the-great-search-solder-leaded-lead-free-and-silver-bearing-thegreatsearch-digikey-adafruit-digikey-adafruit/) and 'scopes (https://blog.adafruit.com/2022/06/14/the-great-search-a-good-beginner-oscilloscope-thegreatsearch-adafruit-digikey-adafruit-digikey/) that are all available from Digi-Key, just like small components. Did you know that you can also get full-on 3D printers? And why not? We love 3D printing for enclosures and prototyping. (https://www.thingiverse.com/adafruit/designs)
Digi-Key is now a stockist of Creality 3D printers (https://www.digikey.com/en/supplier-centers/creality-3d), from the popular CR-10 (https://www.digikey.com/short/n07ww0wv) to the brand new Ender-3 S1 Pro. (https://www.digikey.com/short/05nrjnh5)
Creality’s Ender-3 S1 Pro high-temperature printer is equipped with CR-Touch automatic bed-leveling, the Sprite full-metal direct dual-gear extruder, a 32-bit silent mainboard, and more at a very affordable price point. The innovative Sprite dual-gear direct extruder has an extrusion force of 80N and enables smooth feeding. The Ender-3 S1 Pro supports printing with flexible filaments (TPU) and other filaments (PLA, ABS, wood, TPU, PETG, and PA). The CR-Touch auto-leveling allows for quick, accurate, and complete leveling, as well as providing automatic compensation for a 16-point printing height on the heat bed. The nozzle is made of brass, enabling high-temperature printing up to 300°C. The Ender 3 S1 Pro is an improved version of the very successful Ender 3.
The 4.3-inch LCD enables click-to-control, supports nine languages, and will automatically dim for energy-saving if there is no action for three minutes. The Ender-3 S1 Pro is certified to international standards. Creality provides after-sales service for the printer (12 months) and for wearing parts (3 months).
Features High-temperature printing: up to +300°C Supports multiple filaments: PLA, ABS, wood, TPU, PETG, and PA Sprite direct extruder: 80N extrusion force for smooth feeding Accurate and efficient CR-Touch auto-leveling Durable PEI spring steel build plate with good adhesion 4.3-inch LCD with an easy-to-use interactive UI enabling click-to-control 96% pre-installed, six-step assembly Laser engraving unlocks creation potential Certified to international standards Quality guarantee: after-sales service for the printer (12 mo.) and wearing parts (3 mo.)
These printers are very popular with makers, students and engineers: they are fairly easy to set up and have auto-leveling/calibration. We happened to pick one of these up a few months ago, had it put together in a few hours on the weekend, and printing. The quality is great, and we've had no issues with clogged nozzles or failed prints. If the last printer you owned was a Cupcake kit, you'll be impressed with how far printers have come these days. It's common to get touch screens, WiFi control, cameras, configurable temperature and pre-heat, and firmware upgrades. No special tools, soldering or Arduino coding is required to assemble, either.
Once you've got your printer going, check out the Ruiz Bro's 3D Hangouts playlist for hundreds of videos with tons of info on how to create great looking, easy-to-print designs. (https://www.youtube.com/playlist?list=PLjF7R1fz_OOVgpmWevin2slopw_A3-A8Y) We've also got a huge collection of models for various Adafruit boards (https://github.com/adafruit/Adafruit_CAD_Parts) to make it easy to integrate them into your design.
Digi-Key also stocks hundreds of different spools of filament (https://www.digikey.com/en/products/filter/3d-printing-filaments/944), so be sure to pick up some fun colors or materials to go along. There's also a huge number of accessories available if you need replacement nozzles, fans, heaters, beds, etc. (https://www.digikey.com/en/products/filter/3d-printing-accessories/956)
If you want to get started with 3D printing, you can order today and have it delivered from Digi-Key's US warehouse for immediate shipment with no import shipping issues. Save some money with UPS ground, or if you're on a tight deadline, send a Creality Ender 3D printer (https://www.digikey.com/short/05nrjnh5) by air so you can be extruding by tomorrow afternoon!

woooooo our reel of TCA8418's https://www.digikey.com/en/products/detail/texas-instruments/TCA8418RTWR/2172843 is on the way which means its time to wrap up this board we started designing 2 years ago! this chip can do 8x10 keypad matrices and handles a queue of 10 events over I2C with an IRQ line. It works pretty well once you get a hang of how the GPIO/Keymatrix interrupts work. now that we've got the python library https://github.com/adafruit/Adafruit-CircuitPython_TCA8418 all sorted out its time to wrap up the Arduino code and get this board into the adafruit shop.

A couple weeks ago, we showed off a design for a TCA9548 1-to-8 I2C multiplexer. We wanted to take a look and see if there's a chip that's similar but a 4-channel version, since most folks don't necessarily need 8 of a duplicated sensor. Turns out, finding such a thing took a few extra steps and we wanted to show off how we may source a part that's a li'l non-standard!

Happy Sunday folks! This weekend we spent some time getting back to the camera boards and breakouts we designed a while ago. i wanted to try using cameras with esp32 with the esp32_camera module since we're now using that in circuitpython (https://github.com/adafruit/circuitpython/pull/6684) for a wide collection of camera chipset support in the espressif family. folks who have used esp32 for big projects in arduino know that the build platform can be a lil slow, so we're trying out platform.io which has 'official' support from espressif. This is our first time using it in a long time but we got a workflow going. On the 'stemma sunday' front, we are also returning to a keypad driver using the TCA8418, as we were able to get a reel of chips. This is a 80-key matrix driver over i2c and it even has linux kernel support! we're starting on a CircuitPython driver and so far have much of the gpio capability written out.

We've liked the LC709203 https://www.digikey.com/short/p2fpd502 for a while as a low-cost, no-sense-resistor-needed battery monitor. Sadly, the TQFN version is obsolete https://www.digikey.com/short/p2fpd502 and we're using the BGA version https://www.digikey.com/short/7549bd81 for now but...it's also end of line! Let's source a low cost (less than $2 in qty), I2C, resistor-less, 1-cell lipoly monitor chip that we can use when we run out of our LC709s.

This week's EYE ON NPI is making the rainbow connection - it's the ams OSRAM AS7343 Spectral Sensor (https://www.digikey.com/en/product-highlight/a/ams/as7343-spectral-sensor). This is a great update to the AS7341 11-channel sensor (https://www.digikey.com/short/p4vv8b5w) we released a STEMMA QT breakout (https://www.digikey.com/short/n8bv0j9w) for a few years ago.
ams OSRAM's AS7343 is a 14-channel, highly versatile, multi-purpose spectral sensor that enables consumer, commercial, industrial, and laboratory applications. It is optimized for reflective, transmissive, and emissive measurements including color matching, fluid or reagent analysis, or general spectral reconstruction. The spectral response is defined by individual channels covering approximately 380 nm to 1,000 nm with 12+2 channels: 12 in the visible spectrum (VIS) to near-infrared (NIR) range, a clear channel, and a flicker channel.
The AS7343 is an interesting bird - most light sensors only support RGB and maybe IR / Clear diodes. That means you can often get a fairly good 'human eye spectral response' (https://en.wikipedia.org/wiki/Spectral_sensitivity) of the color that is being detected. However, the sensors cannot determine whether they are seeing something that is truly 'orange wavelength' (https://en.wikipedia.org/wiki/Spectral_color) or if it's a mix of RGB that just looks orange. This doesn't matter too much for if you're trying to detect the color of a Skittle (https://techcrunch.com/2017/02/06/this-candy-sorting-machine-isnt-the-hero-the-world-wants-but-its-the-hero-the-world-needs/) but if you're trying to determine the spectral radiation of a material (https://publiclab.org/notes/homechemist/08-24-2018/diy-high-resolution-spectrometer) - you really want to be able to detect the actual wavelengths.
The AS7343 is a remarkably inexpensive sensor for being able to detect 14 channels: 12 wavelengths plus a clear and flicker output channel. That's also 4 more wavelengths than the AS7341! Great for scientific experimentation, LED color calibration, miniature optical spectrometers, etc. Interfacing is pretty simple: you just need I2C and a 1.8V power supply. It even looks like it's pin-compatible with the AS7341 so you could probably use our open source breakout board files (https://github.com/adafruit/Adafruit-AS7341-PCB) and our Arduino/C (https://github.com/adafruit/Adafruit_AS7341) or Python (https://github.com/adafruit/Adafruit_CircuitPython_AS7341) libraries to jump-start your design.
Best of all, the ams OSRAM AS7343 Spectral Sensor (https://www.digikey.com/short/qw708dhm) is available and in stock at Digi-Key right now for immediate shipment. Order today and you can be sensing the rainbow by tomorrow afternoon.

You can build an IoT telegraph with analog feedback servos, QT Py ESP32 S2 and Circuit Python. Inspired by ship engine telegraphs, this uses analog feedback servos to make a simple yet modern two way communication system.
Learn Guide https://learn.adafruit.com/two-way-display-with-analog-feedback-servos/
Code on GitHub https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Two_Way_Servo_Telegraph/code.py
Use it to keep in touch with a friend by letting them know when you want to grab a bite to eat, go on a walk or get together for a cup of coffee.
These Emojis represent the activities you’re interested in and the 3D printed handle lets you select the one you’d like to do.
A piece of copper tape is used to detect when it’s being held and released thanks to the magic of capacitive touch.
The analog feedback servo keeps track of the handles position and sends it over WiFi using Adafruit IO as the broker.

This weekend we've been noodling around with the new ESP32 support for circuitpython. The ESP32 doesn't have mass storage but it does have wifi, so we can use that as a way to connect to the REPL and also transfer files. This stuff is all very very new in circuitpy 8.x but there's a definition for the odroid go, and it's a handy board to use because it's got a screen and battery built in for wireless testing. We also wrote up a driver for the max17048 https://www.digikey.com/short/m5n5n47f a lipo battery gauge much like the LC709 that we use. it's even in stock!
The Great Search - a non-sense-resistor Lipoly battery monitor replacement for LC709203 https://www.digikey.com/short/nqr9zf5b
We've liked the LC709203 https://www.digikey.com/short/p2fpd502 for a while as a low-cost, no-sense-resistor-needed battery monitor. Sadly the TQFN version is obsolete https://www.digikey.com/short/p2fpd502 and we're using the BGA version https://www.digikey.com/short/7549bd81 for now but...it's also end of line! Let's source a low cost (less than $2 in qty), I2C, resistor-less, 1-cell lipoly monitor chip that we can use when we run out of our LC709s.

scott and dan just merged in Web (WiFi) Workflow for circuitpython and ESP32 (https://github.com/adafruit/circuitpython/pull/6685) which means that it's incredibly easy to start working with chips like the ESP32 which have excellent WiFi networking but do not have USB mass-storage.
we want to have CircuitPython run on these chips but of course we ALSO want to have a great user experience for beginners, and being able to pop open a serial terminal or upload files via a browser's drag-n-drop capabilities would be sweeeeet.
we pulled out an odroid go (https://www.hardkernel.com/shop/odroid-go/) which was a popular ESP32 WROVER-based game console, and uploaded the code with esp32 loader (https://espressif.github.io/esptool-js/) .
then we configured the AP and SSID password (https://docs.circuitpython.org/en/latest/docs/workflows.html) - this will be done more automatically in the future, for now its done manually with some REPL commands.
Now when we visit the IP address displayed on the odroid's screen, it will let us immediately go to the built-in serial console that is also web-compatible! any repl commands are echoed on the display as well. next up we will try uploading files.

This week's EYE ON NPI is taking us on a deep dive into the world of waterproof pressure sensors - it's ST's LPS28DFW Dual Full-Scale, Absolute Digital Output Barometer (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/lps28dfw-digital-output-barometer), an easy-to-use I2C temperature and pressure sensor that can go down to 4060hPa for use underwater!
We have used and highlighted many pressure sensors (https://www.adafruit.com/?q=pressure+sensor&sort=BestMatch) over the years here at the 'fruit including the ST LPS22 (https://www.adafruit.com/product/4633), ST LPS25 (https://www.adafruit.com/product/4530) , ST LPS33 (https://www.adafruit.com/product/4414) and ST LPS35 (https://www.adafruit.com/product/4258). Yep that's a lot of ST pressure sensors! Each one has slightly different precision: like many companies making sensors, ST has gotten better and better at making sensors, with each new model getting better accuracy/precision.
The LPS28 is a big step up in capabilities - almost all baro/pressure sensors are good up to 1060hPA which is basically sea level pressure (naturally 1013hPA) or in a high pressure weather system. The moment you want to go underwater (https://en.wikipedia.org/wiki/Underwater_diving), the ambient pressure increases rapidly by 1 Bar (equal to "1 Atmosphere" or 1000hPa) for every 10 meters. That is to say, 10 meters down you'll be at 2000hPa, and at 30 meters, 4000hPa! But, like we said - most pressure sensors folks use cannot be used at such low pressures - which is why this sensor is the diggity - not only does it have a waterproof gel but you can actually use it underwater!
The interface for this sensor is also nice and easy: I2C or I3C (https://blog.adafruit.com/2022/05/12/eye-on-npi-nxp-p3s0200gm-i3c-switch-with-hardware-select-and-enable-eyeonnpi-nxp-digikey/) with one address pin and one alert/interrupt pin. The sensors are calibrated in the ST factory and thankfully are loaded into the ASIC on boot, so you can just read the pressure directly from the I2C register address without doing any funky math.
Ready to dive into using this sensor? You are in luck as there's even an eval board available (https://www.digikey.com/short/42rrvp2v) for quick connection and testing without any soldering required. And of course, this ST LPS28DFW NPI is available and in stock right now at Digi-Key for immediate shipment (https://www.digikey.com/short/1wrmj51m). Order today and you'll be swimming in sensor data by tomorrow afternoon!

Another day, another part we can't get! This week we're on the hunt for a replacement for the FAN5333 (https://www.digikey.com/short/bc3jrj8w), a constant-current, 24V boost converter that we use for our TFT displays with big back lights like the 4.3" touchscreen (https://www.adafruit.com/product/1591). These displays often have 6 or 7 white LEDs in series, and sometimes multiple strands of them! That means boosting 3.3V or 5V up to 22VDC with 50 to 100mA of current. That's a lot of power! Let's find a good alternative at Digi-Key so we can keep making display breakouts that folks love - ideally one that is drop-in compatible with the FAN5333 or at least one with minimal design changes required.

Hey remember when we were revising all our CP2014 boards for the CP2102N? Next up is the metro mini (https://www.adafruit.com/product/2590) an Atmega328 board that we use often for breadboardy Arduino projects. like other boards that need a respin, we approached it with a "well, while we're here, lets do a gut renovation" - so in addition to swapping the usb serial chip, we also changed the USB to type C, changed some 0805 parts to 0603, and added a STEMMA QT port. one other change is we are having some difficulties getting the 32-TQFN of the '328, but we did snag about 8000 of the 28-TQFN so this 'V2' uses that part for now. it really is a 'design with what you can get' time! We also played with the AGS02MA gas sensor and wrote some drivers for it, and started on the code for our GUVB I2C UV sensor we designed a while back since it's nice and sunny for testing!

This week's EYE ON NPI can measure the air-speed velocity of an unladen European swallow (https://interestingengineering.com/science/monty-python-and-the-holy-grail-airspeed-velocity-of-an-unladen-swallow), it's the Renesas FS1015 Air Velocity Module,(https://www.digikey.com/en/product-highlight/r/renesas/fs1015-3000-air-velocity-modules) a nifty sensor that can measure air-speed velocity up to 15 meters/second.
What's interesting about this sensor is it does not use an impeller like many flow sensors we've seen (https://www.adafruit.com/product/833) or air cups like a wind-speed sensor (https://www.adafruit.com/product/1733). Instead, there's a MEMS thermopile sensor that can detect flow across it and generate a signal to indicate wind speed.
The FS1015 looks like it's a next-generation version building off of the IDT FS1012 (https://www.digikey.com/short/7jdv3w9p) which also uses the same technology (https://www.youtube.com/watch?v=Wvr7aszwRPU) but is designed for liquid or gas. So if you want a similar version of this sensor but with a barbed tubing connection, check out the FS1012/FS2012. (https://www.digikey.com/en/product-highlight/i/idt/fs1012-fs2012-high-performance-mems-flow-sensor-modules) Both of these families of sensors use a silicon-carbide covered sensor with no cavities or moving parts, so there's less risk of clogging or mechanical wear.
Compared to the earlier FS1012, the FS1015 module is mountable with 5 pins, and has both analog and digital I2C output, making it great for use with just about any microcontroller or microcomputer board. There's also mounting ears for quick attachment. The pins are 0.1" spacing so they're easy to use with a cable extender or plugged into a perf/breadboard. There's two models (https://www.digikey.com/en/product-highlight/r/renesas/fs1015-3000-air-velocity-modules), both have 12-bit digital output, but one ranges up to 7.5m/s and the other is 15m/s - so pick which one gives you the range and resolution best matching your expected setup.
The I2C digital interface is simple and reliable: the sensor continuously measures the air speed, and when requested, will send 5 bytes of data over I2C on address 0x50. Three bytes are CRC/checksum, and two bytes make up the 12-bit reading. We were able to whip up an Arduino demo to read the air speed in 5 minutes - just request 5 bytes every 10 ms and plot it out!
For quick, reliable and easy-to-interface air-speed velocity sensing, the Renesas FS1015 Air Velocity Module (https://www.digikey.com/short/pdw5q784) will do a great job without the risk of a mechanical failure. It's easy to add to any system with I2C or analog inputs, and has a nice enclosure design to boot. Best of all, it's in stock right now at Digi-Key! (https://www.digikey.com/short/pdw5q784) Order today and Digi-Key will ship it out faster than a swift so that you can be integrating it by tomorrow afternoon.

We have a tried-and-true microSD card holder (https://www.digikey.com/short/4tmnwh) that we have been using for all our designs, it's a SMT push-pull design that has a lot of source variants, so it's great for everyday usage. We even covered it on a previous Great Search (https://blog.adafruit.com/2021/02/02/the-great-search-micro-sd-card-holder-thegreatsearch-digikey-adafruit-digikey-adafruit/).
But now we have to go back and source again - because for our new Raspberry Pico Cowbell add-on plans, we need a much skinner design that will fit between the SMT headers that will keep the Pico attached and we're about 1mm too wide! No problem, we looked around our parts bin to see what some other products we have use one and liked the one on the Teensy boards, which are also pretty skinny - let's source something equivalent and get it loaded it to our CAD software for usage.

just before sending off our PCF8574 gpio expander breakout board, we noticed that the package we were using (QFN) was no longer available...but we COULD get the TDFN version. so a lil swapperoo and reroute occurred right before ordering the panels. super risky because we didn't test the footprint but we were pretty confident. anyways, we did want to test before our big initial fabrication run so this is us snapping off a board and hand-pasting. turned out great and we'll be making this breakout next week!

Hey everyone! we are back at our desk, its toasty out so we're staying in during the day and cranking out some designs. one project we think we might be able to work on this summer is a de-zombification of the EZ-Link and EZ-Key boards from many years ago. these bluetooth classic boards rocked but suffered from using a really frustrating development and sourcing process. so we're gonna try to 'port' the designs from CSR to ESP32. this week we also started working on some cowbells! we have a proto-'bell done and we tacked it onto a proto pcb order, and we're also starting to work on a TFT 'bell.

This week's EYE ON NPI is OK with you going back to sleep...shhh! Rest up, it'll wake you up when it's time to go...we're reviewing the new ABLIC S-35710/20 Series Convenience Timer ICs (https://www.digikey.com/en/product-highlight/a/ablic/s-35710-20-series-convenience-timer-ics). These are a great solution for when you need to turn a non-low-power system into something that sips power.
When we first started on our embedded electronics journey, with boards like the Arduino, power management wasn't a high priority: you'd plug something into DC or USB power and it would sit there blinking lights or moving servos. Even if you did have a battery-powered project, those same LEDs or motors would be so high-power consuming that trying to optimize power wouldn't be a great use of time: anyways the regulator and chip are just not designed to be low power (https://analysisnorth.com/articles/arduino-for-a-year.html) and would need replacing, something that would add significant cost.
For many years, folks were basically ok with this arrangement! Chips did start having sleep modes, but it was not surprising that one would have to re-design or spend more just to get low power performance. Then, with the proliferation of low cost and low-power-optimized WiFi (https://www.digikey.com/en/supplier-centers/espressif-systems) and BLE chipsets (https://www.digikey.com/en/supplier-centers/nordic-semiconductor) plus low cost LiPo batteries, the demand for devices that can last for days or weeks on a rechargeable battery became a roar. Now it's expected that any design can become a low power one.
OK cool - but what if you're dealing with a chip or module that does not have ultra low sleep - say you want to use the cool new Pico W from Raspberry Pi - but the RP2040 chip's sleep current is 0.2mA (https://forums.raspberrypi.com/viewtopic.php?t=316458). That's low but perhaps not low enough for your needs. The ESP32 series, by comparison, can hibernate at 0.005mA / 50uA, 1/25th the current. But perhaps even that is considered too much! Or perhaps it's the regulator that is drawing more current - 50uA or more is pretty normal for an LDO.
That's where the ABLIC S-353710/20 Series Convenience Timer ICs comes in! (https://www.digikey.com/short/z952dntf) If your use case has consistent and periodic wake-ups, these chips can be programmed via I2C to wake up every 'n' seconds with a 24 bit counter. That means you can go from 1 second to 2^24 seconds, 194 days! The output can control a power transistor or enable-pin for your power system, to give you the lowest-possible current draw: since the chip can run from 2 to 5V, just power it directly from your battery input. Current draw is about 0.2uA, which beats even the lowest-power microcontrollers or LDOs.
There are three versions of this family, the S-353720 (https://www.digikey.com/short/r797trjn) which uses two pins to set fixed wake-times of 1, 10, 30 and 60 seconds. We recommend the MSOP version of the S-353710 (https://www.digikey.com/short/f2j7dhqp) which is I2C programmable up to 194 days. Finally, there's also the SOIC version of the S-353710 (https://www.digikey.com/short/dj9tzz1q) which is basically the same as the MSOP one, but has a built in crystal for simpler assembly but higher cost.
No matter which version you choose, all types of ABLIC S-353710/20 Series Convenience Timer ICs (https://www.digikey.com/short/z952dntf) are in stock at Digi-Key for immediate shipment! Order today and they will not snooze even 1 second before packing your order and sending it to you, so you can get working on optimizing your design to the lowest power possible by tomorrow afternoon.

Many devices and sensors like it if you give them a fancy reset pulse after power has come up, particularly displays and OLEDs! But sometime for wiring simplicity we would like to skip using a microcontroller pin, and have the breakout board autoreset on power loss. In such cases we use a 'power on reset' chip such as the APX803-26SAG https://www.digikey.com/en/products/detail/diodes-incorporated/APX803-26SAG-7/2285963 . It's worked great but....it's now discontinued! Lets find a drop-in replacement. We will need a SOT-23-3 with pin 1 ground, pin 2 open-drain reset and pin 3 VCC. The reset pulse should be about 100ms, VCC should be able to be 3 to 5V, and the reset level about 2.7V, and hold down the reset line for at least 10ms. The challenge is there's a lot of options, but they're not all function/pin compatible!

This week's EYE ON NPI is bumpin' the tunez, it's Analog Devices (nee Maxim) MAX98365 Amplifier, a 14 V plug-and-play digital Class-D amplifier with a highly flexible digital audio interface that supports just about any kind of digital encoding. This amplifier has a wide input power range, wide logic voltage range, and can handle just about any digital audio formatting you want to throw at it:
The digital audio interface is highly flexible. The devices support I2S, left-justified, and 8-channel TDM data formats. The digital audio interface accepts 8 kHz, 16 kHz, 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz sample rates. Data words can be 16-bit, 24-bit, or 32-bit in I2S and left-justified modes and 16-bit or 32-bit in TDM mode. Digital audio interface input thresholds are ideal for interfacing to 1.2 V and 1.8 V logic. The devices can tolerate logic input voltages up to 5.5 V.
The NPI's part number, the MAX98365 (https://www.digikey.com/short/m85rvjwh), sounds similar to an I2S amp chip we've been using for a while - the MAX98357 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/3006/6058477) - and to no surprise, this chip seems to be an upgrade to the original amp. Both are single, class-D amplifiers, but the new chip has much better power supply range: 3V to 14V instead of 3 to 5V, which also allows it to max out the speaker power at around 14 W into a 4 or 8Ω load with 10% Total Harmonic Distortion (https://en.wikipedia.org/wiki/Total_harmonic_distortion). For 1% THD you can go up to 14W in 4Ω or 8W into 8Ω.
The nifty thing this chip can do is swap formats based on the kind of signal it gets - which means you can use it in a range of designs. Most folks tend to use I2S, but left-justified or 8-channel TDM is also supported. It does this by auto-detecting the signal frequencies and pulse types. It also has the nicety of no MCLK pin required - which will be nice to hear for folks using this with single board Linux computer like Raspberry Pi that do not have MCLK output. Also, you get to save a pin if you are using I2S on a microcontroller! (https://learn.adafruit.com/adafruit-max98357-i2s-class-d-mono-amp/circuitpython-wiring-test)
OK, so this chip is quite magical, but there's one thing to watch for - it's only available in a chip-wafer-scale BGA package with 0.4mm pitch (https://pdfserv.maximintegrated.com/package_dwgs/21-100536.PDF). This makes it great for embedding in tiny devices, but rough for prototyping. So you may want to check out the MAX98365AEVSYS eval board (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/MAX98365AEVSYS/16187640) which can at least get you set up before you start routing. Next up, even if you are not too scared of 0.4mm pitch, the gain select pin is in the center, which means you can at least avoid plugged vias if you're willing to live with a fixed gain.
If you want a itsy-bitsy-tiny-winy amplifier with great output, wide support for different formats, and class-D efficiency, the Analog Devices MAX98365 Amplifier is a great pick! And, best of all, it's in stock right now for immediate shipment from Digi-Key. (https://www.digikey.com/short/m85rvjwh) Order today and you will be blasting the hit song of the summer by tomorrow afternoon

Here's one by request! A customer posted on the Adafruit forums asking what is the matching connector for our RGB matrix power ports (https://forums.adafruit.com/viewtopic.php?f=8&t=192484). We googled real fast but did not find a definitive answer, and this kinda thing comes up pretty often - how to find the part number for a generic cable you received in a product) so let's go through how to use Digi-Key's great search and product photos to find the most likely match!

This week's EYE ON NPI will easily smooth your day, clearing out all those nicks and scratches that have built up, with a Jonard Tools Rapid Deburring Tool (https://www.digikey.com/en/product-highlight/j/jonard-tools/rapid-microduct-deburring-tool). We were first introduced to one of these tools at the Media Lab, where we immediately fell in love with the easy-to-use tool that cleans up edges and curves with a smooth swipe. Deburring tools are traditionally used for cut tubing and pipe, to get rid of the gunk left over from saw cuts. But they're also excellent for cleaning up drill holes / making countersinks, and for 3D printed parts where-ever you want to smooth corners and edges. We've even used them to enlarge holes if you just need a li'l more clearance!
Using a deburring tool (https://www.digikey.com/short/3jvhv79m) is simple - the blade snaps into a smoothly rotating roller bearing, so you can replace it when it gets dull. Insert or place the blade against the edge to clean up, then swipe while using your thumb to supporting a smooth motion. It might take a few tries your first time to get the hang of the pressure needed to make an even slice. The sharp blade can be used on various metals and plastics - anything softer than stainless steel.
Jonard’s deburring tool is designed for deburring the insides of microduct tubes. This tool is perfect for preparing the insides of fiber optic microduct tubes for termination and removing debris from 3D printed parts. Replacement blades made from tempered high-speed steel (HSS) are also available.
Features:
-Blade made from tempered HSS for maximum sharpness and durability -Ergonomic rubberized handle provides a secure and comfortable grip while deburring -S-shaped blade cleanly deburrs the edges and insides of microduct tubes -Can be used on brass, steel, aluminum, copper, or PVC pipes -Lifetime warranty
This tool is great for prototypers and makers - you can skip the sandpaper or filing and since the part is hand-held while deburring you don't have to worry about clamping or jigging. Don't forget to pick up some spare DB-5RB blades (https://www.digikey.com/en/products/detail/jonard-tools/DB-5RB/16589932) for when they get dull from use.
The Jonard Tools' Rapid Microduct Deburring Tool (https://www.digikey.com/short/3jvhv79m) is available now from Digi-Key for immediate shipment! Order today and you can be deburring everything in sight by tomorrow morning. And while you're waiting the whole day for your next-day order to arrive, check out Jonard's TikTok account for great videos and tips on how to use various hand tools that will level up your making (https://www.tiktok.com/@jonardtools?lang=en)

This week's EYE ON NPI is a cushy new way to wrap and protect products during shipping and storage, without mess or waste - it's the 3M Cushion Lock™ Protective Wrap and Dispenser (https://www.digikey.com/en/product-highlight/3/3m/cushion-lock-protective-wrap-and-dispenser)! This combo kit of die-cut paper and strong steel dispensing equipment is a great alternative to messy, wasteful or hard-to-recycle packaging materials like packing peanuts (https://en.wikipedia.org/wiki/Foam_peanut), bubble wrap (https://en.wikipedia.org/wiki/Bubble_wrap), air packs (https://en.wikipedia.org/wiki/Inflatable_air_cushion), foam balls, or old newspapers. And you don't need any special installations like compressed air or overhead dispenser bins to use it, so it's perfect for companies from 1-maker-in-a-room up to 10,000-packages-a-day-in-a-warehouse.
The most common packaging materials folks use are also the most annoying to transport: packing peanuts and bubble wrap ship pre-inflated so they're massive. Even if they're light, they still take up a lot of space! there are more compact systems like inflate-on-demand sealed air pillows (https://www.sealedair.com/products/protective-packaging/inflatable-air-pillows) but now you need special air system which costs $1000's and is probably quite loud during operation. In comparison, the Cushion Lock ships as a dense roll of die-cut paper, 1000 foot rolls can ship UPS ground from Digi-Key and arrive in a few days. (https://www.digikey.com/short/2tf383mf) When loaded into the dispenser, the paper expands as you pull, and the die cut has li'l saw-teeth that grabs onto itself when wrapped to keep the 3D matrix 'puffy'. It looks like the Geami stuff that Digi-Key includes as a free cat toy with each order (https://www.evilmadscientist.com/2009/digi-key-sends-cat-toys/) but bulkier.
We're investigating sustainable packaging at Adafruit (https://www.adafruit.com/sustainability) and it's great to see easier-to-recycle or compost-able packaging available from 3M (https://news.3m.com/Scotch-Cushion-Lock-Protective-Wrap-delivers-proven-packing-protection-without-the-guilt-of-plastic-all-in-one-simple,-efficient-product) - it has the same poofiness as air-puffed wrapping material, but without the wasteful shipping of pre-puffed-air or expensive inflating equipment. Combined with plain cardboard boxes, and lightweight plastic anti-static bags, this is one of the new options we'll be evaluating and we recommend other companies check out as well!
Best of all, you don't need to talk to a sales rep or sign a contract to get started - both the 3M Scotch Cushion Lock Dispenser (https://www.digikey.com/en/products/detail/3m/PCW-121000-D/16497669) and rolls of 3M Scotch Cushion Lock Protective Wrap (https://www.digikey.com/short/2tf383mf) are in stock for immediate shipment! Order today and choose ground for fast and reliable delivery - Digi-Key will ship it same day - and you can start saving the Earth while also saving money and space for your small-or-large business shipping needs.

This weekend we finally got back round to assembling/testing/coding up libraries for the LIS3MDL-replacement we found a few months ago: the MMC5603 https://blog.adafruit.com/2022/03/21/a-magnetometer-that-you-can-purchase/ We'll be using this in our replacement/updates for the Feather Sense and CLUE board. We also got a whole mess o prototype PCBs in, we can show them off. Finally, we're tuning and tweaking our workflow for how we do library development, and we look at maybe checking out github copilot for coding and openai for documention.
The Great Search - Identifying the RGB Matrix Power Connector https://www.digikey.com/en/products/detail/te-connectivity-amp-connectors/1744036-4/2299265
Here's one by request! A customer posted on the Adafruit forums asking what is the matching connector for our RGB matrix power ports https://forums.adafruit.com/viewtopic.php?f=8&t=192484 We googled real fast but did not find a definitive answer, and this kinda thing comes up pretty often - how to find the part number for a generic cable you received in a product) so let's go through how to use Digi-Key's great search and product photos to find the most likely match!

This week we've got a request from someone who didn't manage to get a J-Link Mini EDU (https://www.digikey.com/short/rh972jb3) before the part shortage kicked in. These things were great for use for programming just about any ARM chip, and are very affordable for students! But you can't get them anymore.
In particular this customer wanted to use Atmel Studio to program and step-debug ATSAMD chips - in which case we let them know about the very-handy AVR-ICE modules. Despite being called AVR In Circuit Emulator, they are also good for any Atmel/MCP Cortex chip. They're also the only debugger/programmer that is supported from within Atmel Studio.
While the boxed ICE adapter is a lil expensive, there's a PCB-only board version we found, just don't forget to pick up a 10-pin SWD cable (https://www.digikey.com/short/r9tfpdn5) while you're there. NB: Yes, these are more expensive than your standard $20 CMSIS-DAP adapters, but if you are really spending a lot of time with AVR/SAM chips, they will save you a ton of time from having to fiddle with OpenOCD and we find they're worth the cost!

This week's EYE ON NPI will pique your curiosity... it's Microchip's AVR-IoT Cellular Mini Development Board featuring the Sequans Monarch 2 GM02S cellular module (https://www.digikey.com/en/product-highlight/m/microchip-technology/avr-iot-cellular-mini-development-board) This dev board really knows how to get us interested with an AVR128DB48 128KB-flash AVR chip (https://www.digikey.com/short/4pq3d2q3), Sequans GM02S compact LTE cell module (https://www.digikey.com/short/4qbfcn17), Feather format (https://learn.adafruit.com/adafruit-feather), Stemma QT / Qwiic connector (https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma-qt) and Arduino library support (https://github.com/microchip-pic-avr-solutions/avr-iot-cellular-arduino-library) This is an excellent dev board to use if you want to take advantage of the huge ecosystem afforded by Arduino, Feather, Qwiic/QT - you should be able to use the many thousands of libraries and hardware accessories for quick prototyping.
As mentioned, this dev board is Feather shaped, with a USB Type C connector, Li-poly battery charger, and built in programmer/debugger/serial interface for the AVR chip. The individual microcontroller is a AVR128DB48 AVR (https://www.digikey.com/short/4pq3d2q3) which comes with 128KB flash and 16KB RAM. Think of it as a super-beefy ATmega328P! A SAMD21E 'curiosity' chip is used as the programming interface and also serial interface. When plugged in, the board shows up as a disk drive, with a getting started guide bookmark and some other specification files. While following the getting started guide we found that you can also drag hex files over to program it, very handy for quick-start! To program it, MCP suggests using the DxCore from SpenceKonde (https://github.com/SpenceKonde/DxCore) in Arduino so you'll want to get that installed while you follow the rest of the guide.
Next up, time to activate the included SIM card from Truphone (https://activate.truphone.com/) that comes with the dev kit. This SIM is free to activate and is good for up to 150 MB of data transfer and 90 days, which is plenty of time to explore the board before needing to renew. Activating the SIM only took us 5 minutes - don't forget to power cycle after activation to make sure the module and SIM re-authorize.
One of the surprises we had while trying this eval board is the really good documentation and learning system that is over at https://iot.microchip.com/avr-iot-cellular-mini - we're kinda used to verbose text-based documentation or using specialized software that only runs on Windows. This is the first time we've seen a really nice documentation system with simple step-by-steps, lots of photos, links and a clear navigation system. There are also two interesting in-browser compilation and serial monitor widgets that we spotted, which is a good sign that folks are starting to move towards browser-and-filesystem replacements for tool-chains.
The Arduino library code is available over at https://github.com/microchip-pic-avr-solutions/avr-iot-cellular-arduino-library which looks like it's got platform.io support and you can download a release for installation into the Arduino IDE. (We do recommend someone at MCP try to add a proper release to the Arduino library manager to save one extra step if possible!) Once installed, there are a few helpful examples to get you going. The first one is just connecting to an HTTP endpoint and parsing out the result and it worked...really well! We were able to connect to the AT&T cellular network and fetch the data within a minute. We'd request an HTTPS example since most folks will want a TLS method of connection!
Since the board is Arduino and Stemma QT compatible, we were able to connect an OLED and extend the example to display the HTTP-gotten data to the OLED - it only took us 10 minutes to install everything for Arduino library support and extend the code which is amazingly fast! You know what else is really fast? Digi-Key shipping for the AVR-IoT Cellular Mini Development Board, cause it's in stock right now! (https://www.digikey.com/short/bn7mp80w) Order today and you'll be connecting to the LTE cellular network by tomorrow afternoon.

On this week's Great Search we're on the hunt for a super-retro component: a connector that will match up with PC Game port connectors like you had on your old 486dx with a Sound-Blaster 16.
We're looking for something through-hole, right-angle, with 2 rows of sockets. We also want the li'l 4-40 hex standoffs that are used to secure the joystick to the connector. Let's see whether we can find it in stock on Digi-Key!

We blogged about this cool project that converts a PC joystick to USB https://github.com/necroware/gameport-adapter and we realized there's probably millions of these old joysticks folks may be wanting to update or interface with. So we threw together a quick PC Joystick QT breakout! I'm using seesaw cause we need analog inputs as well as digital and once you have ADC + GPIO in an I2C project we feel we're best off going with a microcontroller. We also wrapped up an ancient PCF8574 https://www.digikey.com/short/7bvpbqvt QT breakout and wrote a library for it. The PCF8574 is a very wierd little chip which does 'bidirectional gpio expansion' but without a direction port, how's it do that? Tune in to find out! :)

Let's see if we can find some other low cost (~$1) GPIO expanders which have programmable pull-up control (once of our fav things about the MCP series!), IRQ output, and 3V or 5V functionality!

This week's EYE ON NPI is very adaptable - it's CUI Inc's 30 W Desktop USB PD Adapters (https://www.digikey.com/en/product-highlight/c/cui/30-w-desktop-usb-pd-adapters) which have up to 30 Watts of output with a variety of voltages, so they can be used in multiple product designs to make your inventory and procurement simpler! These power adapters will help you transition your products from DC jacks to USB C, which has power negotiation all in one consistent, well-recognized connector.
We've covered DC plug adapters on EYE ON NPI before. Just about every product in the world uses these ubiquitous 'barrel jack' connectors for power (https://www.digikey.com/en/products/filter/ac-dc-desktop-wall-adapters/130): often 5.5mm outer diameter / 2.1 or 2.5mm inner (https://www.digikey.com/en/products/detail/cui-devices/PJ-003A/96969). These connectors are so popular that they don't really 'mean' anything when you see them other than "power connector". There's no inherent voltage, polarity or current capability that is indicated by a barrel jack. You could have 5VDC center-positive 5A adapter (https://www.digikey.com/en/products/detail/cui-inc/SDM36-5-U-P5/8547877) or you could have a 9VAC 300mA adapter, all with the same connector. Only by careful reading and matching of the labels can you verify which adapter you have matches with which product - and if you lose the adapter it could be a real pain to get a replacement.
That's where USB Type C has a lot of potential to improve and simplify this issue: folks end up being scared to toss out their power adapters because you never know when you need it or what the matching devices is, even years later. If, instead, we had one power adapter and cable that would be usable for any product, that would deliver the right voltage, we could mix and match adapters without worrying about under-powering or over-volting. A lot of mobile devices have started to go this way with USB mini or micro B ports, cell phones being the most popular: all USB ports are basically 5V 1A (https://www.digikey.com/en/products/detail/cui-inc/SWI5-5-N-I38/5287192) and if you have something running off of a Lipoly battery, this is plenty to keep you topped up. But for larger devices, ones with displays or motors, or larger battery packs, 5W (or 10W on a fancy high current adapter) is not going to be enough. And you don't necessarily want 5V input! If you have a backlight that requires 12V or a battery pack that is 8.4V it's going to be expensive and wasteful to try and boost 5V USB up to 12V.
USB C's Power Delivery spec is a great solution: it can provide anywhere from 5V to 20V DC, at up to 100W if the power adapter is chunky enough. CUI's awesome blog has a great post about the power delivery specifications with clear text and diagrams (https://www.cui.com/blog/usb-type-c-pd-and-pps) for more info - in particular watch out that you have a current limitation or 3A or 5A at each voltage so you'll never be able to get 5V 20A = 100W. Instead you'd get 20V at 5A. However, if your voltage / wattage use case lies within the PD requirements, you're good to go! You can use a standard USB C connector (https://www.cuidevices.com/catalog/interconnect/connectors/usb-connectors), standard USB C power cables (https://www.cuidevices.com/catalog/interconnect/cable-assemblies/usb-cables?[0].sn=Connector%201&[0].sv=Type%20C%20Plug) - all available from CUI and the CUI 30 W Desktop USB PD Adapter (https://www.digikey.com/short/v0f7fqm2) as the power supply.
Best of all, Digi-Key has tons of CUI 30 W Desktop USB PD Adapters (https://www.digikey.com/short/v0f7fqm2) in stock, the version we're linking to comes with a USA power cable, but they also sell a version without a cable (https://www.digikey.com/en/products/detail/cui-inc./SDI30C-Q-UTB-CUB/16376426) so you can swap out with a UK, EU or other wall plug. Don't forget to also get a high quality CUI USB Type C connector (https://www.digikey.com/short/w23hh4m4) to go with. Order today for immediate shipment!

Hey it's still a chip shortage - here's what we did this week to help manage it! First up, our order of atmega328p's from over a year ago got bumped to late 2023 and at this point we may not even get till 2024. but we wanted to see if we could get a few products back in stock like the feather 328p or metro mini. we did find some atmega328-mmh's in stock at Digi-Key and yoink'ed em. these are non-P type so they are higher power usage and they're 28QFN not 32QFN soooo we need to respin boards but at least we have a couple hundred on hand! Also, as an FYI, LSM9DS1 which we noticed was NRND last week is not officially EOL, we'll be recommending an LSM6DSxx IMU + MMC56x3 magnetometer.
The Great Search - I2C IO Expander (Since we can't get MCP230xx) https://www.digikey.com/short/p3jzv5v4
We've really liked using the MCP23017 https://www.digikey.com/en/products/detail/microchip-technology/MCP23017T-E-ML/964183 and MCP23008 https://www.digikey.com/en/products/detail/microchip-technology/MCP23008T-E-ML/1223120 buuuuut they're totally unavailable. Lets see if we can find some other low cost (~$1) GPIO expanders, that have programmable pull-up control (once of our fav things about the MCP series!), IRQ output, and 3V or 5V functionality!

This week's EYE ON NPI is very adaptable - it's CUI Inc's 30 W Desktop USB PD Adapters (https://www.digikey.com/en/product-highlight/c/cui/30-w-desktop-usb-pd-adapters) which have up to 30 Watts of output with a variety of voltages, so they can be used in multiple product designs to make your inventory and procurement simpler! These power adapters will help you transition your products from DC jacks to USB C, which has power negotiation all in one consistent, well-recognized connector.
We've covered DC plug adapters on EYE ON NPI before. Just about every product in the world uses these ubiquitous 'barrel jack' connectors for power (https://www.digikey.com/en/products/filter/ac-dc-desktop-wall-adapters/130): often 5.5mm outer diameter / 2.1 or 2.5mm inner (https://www.digikey.com/en/products/detail/cui-devices/PJ-003A/96969). These connectors are so popular that they don't really 'mean' anything when you see them other than "power connector". There's no inherent voltage, polarity or current capability that is indicated by a barrel jack. You could have 5VDC center-positive 5A adapter (https://www.digikey.com/en/products/detail/cui-inc/SDM36-5-U-P5/8547877) or you could have a 9VAC 300mA adapter, all with the same connector. Only by careful reading and matching of the labels can you verify which adapter you have matches with which product - and if you lose the adapter it could be a real pain to get a replacement.
That's where USB Type C has a lot of potential to improve and simplify this issue: folks end up being scared to toss out their power adapters because you never know when you need it or what the matching devices is, even years later. If, instead, we had one power adapter and cable that would be usable for any product, that would deliver the right voltage, we could mix and match adapters without worrying about under-powering or over-volting. A lot of mobile devices have started to go this way with USB mini or micro B ports, cell phones being the most popular: all USB ports are basically 5V 1A (https://www.digikey.com/en/products/detail/cui-inc/SWI5-5-N-I38/5287192) and if you have something running off of a Lipoly battery, this is plenty to keep you topped up. But for larger devices, ones with displays or motors, or larger battery packs, 5W (or 10W on a fancy high current adapter) is not going to be enough. And you don't necessarily want 5V input! If you have a backlight that requires 12V or a battery pack that is 8.4V it's going to be expensive and wasteful to try and boost 5V USB up to 12V.
USB C's Power Delivery spec is a great solution: it can provide anywhere from 5V to 20V DC, at up to 100W if the power adapter is chunky enough. CUI's awesome blog has a great post about the power delivery specifications with clear text and diagrams (https://www.cui.com/blog/usb-type-c-pd-and-pps) for more info - in particular watch out that you have a current limitation or 3A or 5A at each voltage so you'll never be able to get 5V 20A = 100W. Instead you'd get 20V at 5A. However, if your voltage / wattage use case lies within the PD requirements, you're good to go! You can use a standard USB C connector (https://www.cuidevices.com/catalog/interconnect/connectors/usb-connectors), standard USB C power cables (https://www.cuidevices.com/catalog/interconnect/cable-assemblies/usb-cables?[0].sn=Connector%201&[0].sv=Type%20C%20Plug) - all available from CUI and the CUI 30 W Desktop USB PD Adapter (https://www.digikey.com/short/v0f7fqm2) as the power supply.
Best of all, Digi-Key has tons of CUI 30 W Desktop USB PD Adapters (https://www.digikey.com/short/v0f7fqm2) in stock, the version we're linking to comes with a USA power cable, but they also sell a version without a cable (https://www.digikey.com/en/products/detail/cui-inc./SDI30C-Q-UTB-CUB/16376426) so you can swap out with a UK, EU or other wall plug. Don't forget to also get a high quality CUI USB Type C connector (https://www.digikey.com/short/w23hh4m4) to go with. Order today for immediate shipment!

We have folks ask us what's a good beginner 'scope to purchase. Turns out that even with a $500 budget, you can get a pretty nicely spec'd out scope that will help you tons in debugging projects.
Since oscilloscopes come in just about every configuration, a lot of picking out a scope is going to be deciding what trade-offs you want with respect to channels, bandwidth/sample rate, and memory size. Let's check out what you can get on Digi-Key to kickstart your electronics workbench!

We are a-glow with some fun samples this week! We got some neat flexible and non-flex LED filaments we're checking in various colors and styles. Fun fact - we got some LED filaments years ago to stock but they only came in 70V and so we ended up not putting them into the shop because they'd be too annoying to use. We also got some nifty magnetic usb cables and a programmable USB PD cable!

This week's EYE ON NPI is ready to take flight, it's Würth Elektronik's FeatherWing Development Boards (https://www.digikey.com/en/product-highlight/w/Würth -electronics/featherwing-development-boards) a quadruplet set of red boards that can add Würth Technology and innovation to your favorite Feather mainboards no matter what platform you are using.
Adafruit Feather is a complete line of development boards from Adafruit and other developers that can be stacked or used individually. They can be powered by LiPo batteries for on-the-go projects or by micro-USB plugs for stationary use. Feathers are lightweight, portable, and flexible.
FeatherWings are stacking boards that add functionality and space for prototyping. Adafruit Feather is a complete ecosystem of products and an excellent starting point for user projects.
When we designed the Feather format oh-so-many years ago at Maker Faire 2015 (https://atmelcorporation.wordpress.com/2015/09/30/exclusive-ladyada-shows-off-adafruits-brand-spankin-new-feather-board/), we purposefully made the shape and pinout an open standard (https://learn.adafruit.com/adafruit-feather) so that other companies could contribute and create their own license-free design, heck they can even use the words Feather and FeatherWing as long as they make it compatible. Digi-Key has been a great partner for us in stocking Feather boards (https://www.digikey.com/en/products/result?s=N4IgTCBcDaIGYFMCGAXAFggTiAugXyA) with hundreds of Feathers, 'Wings, adapters and eval boards.
What we think makes Feather so great is that it is not platform-specific. Energia boards are only MSP430 (https://energia.nu/guide/boards/) and Nucleo are only STM32 (https://www.st.com/en/evaluation-tools/stm32-nucleo-boards.html), Arduino shields are more universal but they can be a tad large. We've seen feathers with chips from Atmel, Microchip, ST, Maxim, TI, etc. - which means that Würth 's Wings can be used with whatever platform you prefer.
There are four FeatherWings in this collection: Sensor FeatherWing (https://www.digikey.com/en/products/detail/w%C3%BCrth-elektronik/2501000201291/14115778) Temperature (2521020222501), humidity (2525020210001 and 25250202100011), acceleration (2533020201601 and 25330202016011), and absolute pressure sensors (2511020213301 and 25110202133011) All the four sensors are connected over the shared I²C bus Compatible with QWIIC-connect from Sparkfun Easy to expand with WE FeatherWings and hundreds of already existing boards with the Feather and QWIIC form-factor Arduino (C/C++) drivers and code examples available on Github Thyone-I wireless FeatherWing (https://www.digikey.com/en/products/detail/w%C3%BCrth-elektronik/2611059021001/14115775) Thyone-I proprietary 2.4 GHz RF module (2611011021000) Encryption (AES128) Mesh network capable Integrated security/authentication IC Connection to Thyone-I module (2611011021000) or Thyone-I USB stick (2611036021001) Calypso Wi-Fi FeatherWing (https://www.digikey.com/en/products/detail/w%C3%BCrth-elektronik/2610039025001/14115769) Calypso, 2.4 GHz Wi-Fi connection IEEE 802.11 b/g/n (2610011025000) Easy connect to smart devices and servers Handling multiple nodes simultaneously Energy saving mode to support battery powered applications Supports IPv4 and IPv6 Out of the box implementation of several commonly used network applications like SNTP, DHPv4, DHCPv6, mDNS, HTTP(S), and MQTT Direct communication to the cloud MagI³C power FeatherWing (https://www.digikey.com/en/products/detail/w%C3%BCrth-elektronik/2601157101001/14115779) Operating input voltage of 9 V, 12 V, 15 V, 18 V, and 24 V industrial rails Maximum 36 V input voltage Additional USB connector for 5 V input voltage to select by switch Transformation of industrial input voltage to 5 V Transformation of 5 V to 3.3 V
All together they allow construction of advanced wireless sensor nodes: a Wing with plenty of environmental sensors, a Wing that can be used to create 2.4GHz mesh networks, a WiFi Wing to send data to the cloud, and a power adapter Wing that will allow powering from industrial power supplies such as 24VDC. Combine these with your favorite microcontroller and you've got a full demo of the latest Würth technologies! There's a demo of combining wifi + sensor + feather to create a wireless sensor node on the Würth Youtube.
If you want to jam out your Feather boards with some fancy Würth technology, all four of the Würth Elektronik's FeatherWings (https://www.digikey.com/en/product-highlight/w/Würth -electronics/featherwing-development-boards) are in stock for immediate purchase at Digi-Key. We recommend starting with the Würth Sensor FeatherWing (https://www.digikey.com/en/products/detail/w%C3%BCrth-elektronik/2501000201291/14115778) and then checking out the rest of the Würth FeatherWings on the feature page (https://www.digikey.com/en/product-highlight/w/wurth-electronics/featherwing-development-boards) as your project needs grow!

We're interested in implementing an ultrasonic distance sensor on a microcontroller without using a 'standard' off-the-shelf chip with trigger/pulse mode. Also, because we're sorta curious how these things work! But first up we have to acquire some ultrasonic sensors.
It's definitely easier to design a sonar with two elements - one to transmit and one to receive - but perhaps some clever code/hardware design could make it possible to do with one! Let's find a 40KHz ultrasonic transceiver we can get on Digi-Key to start our experimentations.

The RCWL sensor has a lil solder jumper on the back that lets you turn it into "IIC" mode - we tried it out and ... it kinda works! This sensor can be used on an I2C bus, but it doesn't seem to do well if sharing it with other devices. Still, if you have a microcontroller or microcomputer that doesn't have fast GPIO for toggle/pulse or a hardware UART, you definitely can use it for inexpensive sensing. Note that on this QT Py RP2040 we've got the OLED on a different I2C bus which is why it's happily running for hours now. In stock at the adafruit shop! https://www.adafruit.com/product/4742

Chip Shortage is a new feature video by Adafruit's Ladyada to highlight items that are in short supply or possibly "unobtainium" (with no known return date to the market).
This week it is the Diodes AP2112K-3.3 600ma CMOS LDO Regulator, https://www.diodes.com/part/view/AP2112 Digi-Key https://www.digikey.com/short/h7hhqhwt
These are used in many Adafruit boards as it's perfect for powering any number of designs such as sensors and more.
Adafruit is looking for a cool 100,000 pieces to continue manufacturing with this highly used part.
Adafruit is working night and day to keep products in stock and deliver new products during the chip shortage. Visit https://www.adafruit.com/new to see what new items have been released to find redesigned products with chips that are available.

This week's EYE ON NPI is going loooooooooooooong with a fully integrated Long Range radio module + microcontroller - it's the Murata's Type 1SJ Integrated LoRaWAN Module (https://www.digikey.com/en/product-highlight/m/murata-electronics-north-america/type-1sj-integrated-lorawan-module). This nifty wafer-thin chip is an all-in-one compact solution for adding far-reaching wireless without the cost and power requirements of cellular or WiFi. Particularly for compact products that need to stay small and thin, we've never seen a smaller integrated LoRaWAN solution!
This product is a true triple collaboration, combining the second-generation Semtech SX1262 radio frequency IC (https://www.digikey.com/short/342nj2dp) that comes with the licensed LoRa encoding support and an ARM Cortex-M0 STM32L072 microcontroller (https://www.digikey.com/short/z27vc2rn) from STMicroelectronics with 192 kB of Flash memory, and 20 kB of RAM, along with a built-in RF switch.
Having the STM32L0 chip means excellent deep sleep capabilities, so the module can run on a battery - even a coin cell - for a long time. The STM32 also has plenty of peripherals, so whatever data you need to send over LoRa, you'll be able to read and process the data: USB, ADC, I2C, SPI, UART etc.
The RF side of the module is the Semtech SX1262 - they're the company that licenses the LoRa RF specification so basically you're guaranteed to get working LoRa/LoRaWAN support with working code examples. The radio can transmit at up +22dBm for many-mile range, similar to the SX breakouts and FeatherWings we manufacture (https://www.adafruit.com/?q=lora&sort=BestMatch) with official driver code available through mbed (https://os.mbed.com/teams/Semtech/) and GitHub (https://github.com/Lora-net/sx126x_driver).
All together they make for a compact, inexpensive module which saves you money and space over combining the radio plus microcontroller. We like the epoxy-coated slab look and it seems like it would be easy to use in a pick & place + reflow manufacturing line. To get started quickly, you can pick up the Murata LBAA0QB1SJ-TEMP-EVK evaluation board (https://www.digikey.com/short/rz8pmb3j) or two, it comes with Arduino-like headers, antenna connection options and a built in SWD/JTAG programmer debugger for the STM32 microcontroller. Once you've got your code working, the individual Murata LBAA0QB1SJ-296 (https://www.digikey.com/short/cct0q8cd) modules are available on tape & reel - book an order with Digi-Key for shipment as soon as they come into stock!

On last weeks' The Great Search, we spent some time looking for a drop-in replacement for our go-to regulator, the AP2112K-3.3 (https://www.digikey.com/short/q4wh4ftz) and we found some SOT23-5 sized parts that have a fairly low drop-out and fair current output for most of our breakouts - the AP7354 (https://www.digikey.com/short/2bznd7d3).
However what we really need is something with 500mA+ current output that we can use for our Feather/Itsy/QT Py/etc. dev boards. While there are a few other SOT23-5 options that might come into stock that we'll keep our eyes peeled for, we also want to see if we can future-proof our designs to use another footprint, so that we have more options if this part shortage continues for another 2 years. Let's see what's available in smaller-than-SOT23-5 that can provide the same kind of current output!

Chip Shortage is a new feature video by Adafruit's Ladyada to highlight items that are in short supply or possibly "unobtainium" (with no known return date to the market).
This week it is the TI DRV8833 motor driver IC, https://www.ti.com/product/DRV8833 Digi-Key https://www.digikey.com/short/j99bc4vp
These are used in the Adafruit CRICKIT robotics controller https://www.adafruit.com/product/3343
Adafruit is looking for 4,000 to 8,000 pieces to fulfill the backlog of requests for this highly used part.
Adafruit is working night and day to keep products in stock and deliver new products during the chip shortage. Visit https://www.adafruit.com/new to see what new items have been released to find redesigned products with chips that are available.

This week's EYE ON NPI is right on time with the MAX31329 Low Current Real-Time Clock RTC (https://www.digikey.com/en/product-highlight/a/analog-devices/max31329-low-current-real-time-clock), which will fit wonderfully into your power, board size and materials budget no matter how small. We are digging this fully-integrated RTC, with a lot of li'l extras that make it an excellent choice for compact products.
A Real Time Clock a.k.a. RTC (https://en.wikipedia.org/wiki/Real-time_clock) is a specialty chip that is designed to be ultra low power, so even when everything else in the circuit is turned off, it can still sip power from a super capacitor or tiny battery and keep track of time. It's how your computer and devices can go all the way down to 0% power and yet still know what time it is when recharged/re-powered. Note this is different than storage memory because details like your WiFi password don't need updating every second whereas an RTC has to keep ticking second after second until main power comes back up. Just about everything you own has an RTC in it because timekeeping is so essential to functionality.
There are some chips that have built in RTCs but often these are just counters and are not as low power as a true RTC chip. The MAX31329 for example, has a "240nA Timekeeping Current", whereas only the most power-optimized microcontrollers can get below 1uA. Compare it to the DS1307 which has twice the current, ~500nA! With such low currents, you can even use a super cap (https://www.digikey.com/en/products/detail/elna-america/DSK-3R3H703T414-HRL/2171199) instead of a lithium battery to keep time, meaning no special shipping management or battery replacements. Wondering how big a capacitor you'd need? Maxim's got ya covered with their handy super-cap calculator (https://www.maximintegrated.com/en/design/design-tools/calculators/product-design-calculators/supercap.html)
OK, so it's low power. What else is so great about it? We also really like that the crystal is in-package integrated! Every RTC needs a crystal oscillator, the thing that actually does the counting of time. The crystals are almost always 32.768KHz crystals (https://www.digikey.com/en/products/detail/abracon-llc/ABS25-32-768KHZ-T/675361?s=N4IgTCBcDaIIYCMBOcDGB7AdgAgIICEBlMAVgFoBmMAOgHYA2ADgGkAJALTIBUQBdAXyA) so the chips count the vibrations into a 16-bit counter. When the counter overflows, a second has passed. Often the crystal is the same size as the chip, or if it's integrated, the chip is pretty large. like in the case of the DS3231.(https://www.adafruit.com/product/3013) In this case, we keep the nice smol size. A nice side effect of having a crystal integrated is improved tuning! Having a precise crystal, say +-5ppm like the Citizen CM315D32768 (https://www.digikey.com/en/products/detail/citizen-finedevice-co-ltd/CM315D32768HZFT/5970266) adds another 50 cents to the bill of materials. Not needed here, it's inside and tuned to that fancy 5ppm. Ideally they'd have a temperature-compensated version in the future, since that can get the precision down to 2ppm but 5ppm is still four times better than most low cost 32khz crystals.
Finally, a few small but kind details we caught in the datasheet (https://www.maximintegrated.com/en/products/analog/MAX31329.html): the RTC is 1.6V thru 5V logic friendly, so you can use it with any kit you've got. There's 64 bytes of battery-backed SRAM. I2C has a timeout feature in case of I2C bus jitters which happen at low power dips. Automatic power-switchover to battery when main power droops. Trickle charging with built-in diode and various internal resistors. External clock source select, such as GPS 1pps or line power 50/60hz.
This is a nice RTC, at a nice price, and you can book your order for the Maxim MAX31329 at Digi-Key right now (https://www.digikey.com/short/vqrcfdw3) for shipment the moment they come in stock. According to the lead time estimates, this part will be shipping in about 3 weeks / mid-June so you can start designing it into your PCB and chips will come in right when the prototype PCB is complete. While you're waiting you can also pick up one of the MAX31329 shield evaluation boards (https://www.digikey.com/short/ztdw8wfj) which can be plugged into any Arduino-Uno-like microcontroller and also comes with a development board if you just want to use the built in firmware/software.

The chip shortage is the gift that keeps not giving! Our next shipment of our go-to 3.3V LDO, the AP2112K-3.3 is delayed and we use a LOT of these chips - over a thousand a day. Not only do we use it for all our dev boards as a regulator to take USB or Lipo input and drop it down to 3.3V, but it's also on almost all of our breakouts as a regulator that can take 3 to 5V and provide 3.3V output no matter which is used.
For that reason we need it to have very low drop-out. To keep our items in stock, we could change the lower-power breakouts to use a less-current-output version of the AP2112K (500~600mA) and stretch out our current stock!

This weekend we spent most of the days outside, but we did get to one new board! We already make a Feather with an ESP32-S3 8MB module. Espressif recently sent us a few reels of ESP32-S3 mini modules with 4M flash and 2MB PSRAM, so we are spinning a new version of the Feather for this module. It's pin compatible but since the modules look so alike we ran a new PCB with silkscreen to indicate which you have. We also got a big bag of samples we're testing out -we can show you what we got and whether we'll be stocking them!

This week's EYE ON NPI is chillin' and listening to some vibin' beats - we're featuring Nordic's jam-packed nRF5340 Audio Development Kit (https://www.digikey.com/en/product-highlight/n/nordic-semi/nrf5340-audio-development-kit) that will get you going fast with Bluetooth Low Energy audio development with a lovely kit that has everything you need to build both basic and advanced BTLE audio demos that exercise all the new capabilities of BT 4.x and 5.x's native audio streaming technology
Audio was one of the first killer app's for Bluetooth adoption. Who doesn't remember when ubiquitous 'hands-free' headsets (https://en.wikipedia.org/wiki/Headset_(audio)#Bluetooth_wireless_headsets) started popping up in every business guy's ear. For mobile devices, these headsets turned out be quick to pair, and allowed people to talk, or listen to music, while driving or working without wires. Bluetooth classic audio is still incredibly popular today: not just used in headsets but also in Bluetooth speakers (https://www.digikey.com/en/products/detail/klein-tools-inc/AEPJS2/11570486), hearing aids, wireless mics, home voice agents, and more!
When the audio profile was first invented, there were a few, totally reasonable restrictions placed on how it was used. First, it's a point-to-point connection - also called source-sink connection. There's a supplier source of audio - say the MP3 player - and a destination sink like a speaker. Second, the compression codec had to match the processor and battery capabilities of late 90's technology. The first classic codec was called SBC, although recently there are newer codecs that can do a better job with reducing lossyness and, of course, can take advantage of the Moore's-law improvements in memory and processor capabilities. Unfortunately, as one can expect in such a technology space, many of the codecs are patented, licensed, and require per-device fees. Also, unless you know what to look for, it's harder to compare two headsets with different codecs, as another variable that affects audio quality and delay.
While many non-audio/non-keyboard devices have thankfully moved from BT classic to BTLE, mostly in order to avoid Apple's MFI program, there's been a bit of a lag in getting audio devices to switch over from classic to LE due to the high inertia of technological laziness. However, in the last few years, a Really Good Reason to move over has been invented: AirPods! (https://www.apple.com/shop/product/MME73AM/A/airpods-3rd-generation) Yep, when Apple came out with their new wireless Bluetooth earbuds, they had to come up with a custom BTLE protocol - because there's two sinks and one source, and even if you created two connections (one for left and one for right) the source would have to work hard to synchronize audio. Sure Apple can put the time and money into that kind of development, but what about everyone else who wanted to make similar products? That's why when BTLE audio came 'free' with multi-point transmission and synchronization and an improved free codec, folks' ears started perking up.
With Nordic's new nRF5340 ADK (https://www.digikey.com/short/vm7q7fwz), creating advanced BTLE Audio applications is super fast. The nRF5340 is a dual core ARM processor, which means it's easy to have one core dedicated to codec management and DMA audio streaming, and the other core for interfacing and control. The free software examples (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/nrf5340_audio/README.html) come with two main demos right now: a synchronous example for making wireless earbuds, and a broadcast example for sending audio to multiple sinks. Note that for these examples you'll often want two ADKs so you can stream audio to both ADKs as a way to mimic earbuds, for example.
And, have you heard the good news? Digi-key has a TON of the nRF5340 Audio Development Kit (https://www.digikey.com/short/vm7q7fwz) in stock right now for immediate shipment. Each ADK has all the accessory hardware needed to immediately bootstrap your BTLE example project. (Hint, it's also a great dev board for general nRF5340 development, with SD card, built in debugger, power management, Arduino-esque headers, RGB LEDs, and user interface buttons. Pick up two of these dev kits today and you can be jammin' and boppin' by tomorrow afternoon!

This week, we have a request from someone working on a kit with an an audio output - they need to spec out an inexpensive speaker that will play the audio clips in their design and they had a few rough requirements they wanted to hit: the audio driving circuit they're using is 8 ohms 0.25 Watt, so the speaker cant have have a lower power rating or it will blow out. The size is about 2 inches diameter, and it needs to be a round speaker to fit into the PCB. Finally, the audio frequency range is not that wide, we just need to play tones that are about 600 Hz.

There's a full lunar eclipse tonight that you'll be able to see if you're in the eastern half of N America or in S America (https://moon.nasa.gov/news/172/what-you-need-to-know-about-the-lunar-eclipse/) if it isn't cloudy, go outside and look up! Or watch NASA's livestream. We also went to the NJ Rock, Gem, Mineral and Fossil show (https://nj.show/) yesterday with some Fruit Friends and picked up some really sweet gems - we'll show those off live under the overhead. Finally, we pulled out our pocket VNA we ordered many years ago to try it out - Once calibrated, you can use it to check antenna responsivity, we're also going to try to learn how to use it to tune our pi networks for boards where we DIY the RF section instead of using a module.

This week's EYE ON NPI has an extra I bonus feature - we're featuring the NXP P3S0200GM I3C Switch with Hardware Select and Enable. (https://www.digikey.com/short/td77904f) You might be thinking we made a typo there, as you may be familiar with I2C but have you heard of I3C? Yep, that's three I's for ya, and you'll probably start seeing more sensors, devices and microcontrollers that support I3C which is an extension of I2C with many improvements.
I2C is a sensor interface you are probably well familiar with, just about every microcontroller has I2C hardware support, and about half of peripheral devices and sensors use I2C for data transfer or configuration. I2C is easy to wire up: you only need two data lines. It's a fairly simple overall communication system: each devices has a 7-bit address, with 1 bit for read/write commands, then data is sent after. You can put multiple devices on one I2C bus as long as the addresses don't collide, (https://learn.adafruit.com/i2c-addresses) great for low-pin-count setups or chaining. And, hey did you know that NXP invented I2C? Philips, which then became NXP, originally published version 1.0 the I2C specification in 1992 in app note UM10204 (https://www.nxp.com/docs/en/user-guide/UM10204.pdf) - and because it was a well-written, open, and royalty/license-free standard, the entire industry joined in.
But, there are a few things about I2C that can drive folks a little batty. First up is the speed limitations. I2C uses pull-ups for raising the voltage on the 'open drain' connections, but it takes time to charge and drain the capacitance of lines and gate inputs through a resistor. I3C does not use external resistors, instead there's an active pull-up that transitions between Open-Drain and Push-Pull mode. (https://www.mipi.org/node/2604) This reduces power usage and allows I3C to run at a spicy 12MHz, well in line with SPI speeds.
Next up, there's bus contention - woe is the engineer who has to deal with clock stretching on a bus, or missed clocks. I3C thankfully does not permit clock stretching! (https://www.mipi.org/node/1247) peripherals cannot take control of the clock by keeping it pulled down. Instead all devices must respect the clock. "But!" you are saying "what if I'm designing a peripheral and over I3C we get a sensor wakeup or read request, and I'm not ready to immediately answer in time?" Normally you'd have to have to either use polling for a data-ready bit (yuck, uses a lot of power, bandwidth and time) or you can use an IRQ pin. But if you're using IRQ pins then you've just lost the benefits of having a shared 2-wire bus! Well there's another nifty capability in I3C for in-band interruption management where the controller can hand off the bus to peripherals to notify when they are ready to be listened to. There's a great document from NXP showing the high and low level implementation / trace details of I3C vs I2C that we recommend you check out here (https://community.nxp.com/pwmxy87654/attachments/pwmxy87654/tech-days/256/1/AMF-DES-T2686.pdf)
As you start adding I3C controllers and targets into your embedded systems, you may still find yourself dealing with address collisions, or maybe you want to have two controllers connect to one peripheral. Since I3C has a stricter timing requirement for dealing with the high speeds it can perform at, you'll want a switching chip that is designed for I3C. That's where the NXP P3S0200GM I3C Switch will come to your rescue. (https://www.digikey.com/short/td77904f) It's from NXP who helped bring I3C to market so you know it's going to work exactly as the specification intends and will also be back-compatible with I2C devices.
And, best of all, the NXP P3S0200GM I3C Switch (https://www.digikey.com/short/td77904f) is in stock now for immediate shipment from Digi-Key, perfect for placement into your next design. Even if you're only using I2C right now, you'll be future-proof ready for when sensor and chip revisions start coming out with I3C support. Order today and you'll be switchin' by tomorrow afternoon.

We are working on getting our NAU7802 Stemma QT breakout into the shop - this is a 24-bit ADC with differential input support, and programmable gain for quick interfacing to strain gauges and other Wheatstone bridge-like sensors. Great news is we got a shipment for our order from Digi-Key, but they're out of stock again with a long lead time. Let's find an alternative ADC for folks who want to measure similar small-signal sensors!

We have some fun Azure for IoT projects coming up, but before we get to them, we wanted to test out the CircuitPython AzureIot library over at https://github.com/adafruit/Adafruit_CircuitPython_AzureIoT with the new-ish ESP32-S2 TFT Feather. We set up a new device type that would report temperature, humidity, pressure and battery percentage. Then we provisioned a new device and adapted the example to report data from a connected BME280. There's a small fix we need to make to the NTP library to support raw sockets on native wifi devices but otherwise it works very well!

This week we did a lot of sample testing! First up is this cool conductive rubber sheet. We sell conductive rubber cord, but we had a recommendation to get some 2D shapes as well. This material is easy to cut and has some changing resistance with movement. We also got a motorized potentiometer sample, which is super fun - we're using a simple H-bridge to send the 10K slider back and forth. Finally we're working on our NAU7802 tester, since our order of NAU7802 chips finally came in. This is a load cell amp chip that has I2C interfacing, but really it's for any precision wheatstone-bridge-like things.

we got a motorized pot sample in and wanted to test it out. this is a 10K linear slide pot with a small 5V motor on the bottom that has a small belt to move the slider automatically. some very fancy a/v boards use these so you can quick change presets. we're testing the motor movement with a DRV8830 STEMMA QT breakout we designed before covid and then sorta got distracted from. the pots are on order now, and we'll also try to release this lil breakout!

Chip Shortage is a new feature video by Adafruit's Ladyada to highlight items that are in short supply or possibly "unobtainium" (with no known return date to the market).
This week is the ST Microelectronics STM32F405 microcontroller, used on the MicroPython PyBoard. The shortage unduly affects small manufacturers like MicroPython.
Adafruit is working night and day to keep products in stock and deliver new products during the chip shortage. Visit https://www.adafruit.com/new to see what new items have been released to find redesigned products with chips that are available.

This week's EYE ON NPI lifts up its skinny arms like antennas to heaven - it's the Taoglas family of Wide Band Antennas, featuring the Taoglas WARRIORX PA.760.A (https://www.digikey.com/short/td8wnqd2) with a chonky 600MHz-6000MHz range of functionality, for use with almost any kind of IoT wireless protocol.
Wide band antennas are needed these days because we've moved from simple cellular devices like 2G/GSM that use at most a 'quad band' of 850/900/1800/1900MHz (which you'll note has two narrow bands that are 2x the frequency) in order to cover the globe, to multi-band and multi-protocol modules. If you have something with LTE which has close to 100 different bands (https://en.wikipedia.org/wiki/LTE_frequency_bands) that span from 700 MHz up to 2.6GHz (https://www.sqimway.com/lte_band.php) depending on the LTE Category they cover. Lower categories carry data slower like simple machine IoT signals but farther, higher categories carry faster data like video but cant reach very far.
You could also use this sort of antenna for multi-protocol IoT devices. Lets say you have a horse farm in Ireland (https://www.google.com/search?client=firefox-b-1-d&q=irish+horse+farm) you want to monitor. You've got 50 horses, roaming your property. You want to know their location so you can locate them, maybe some details like their temperature and recent activity (e.g. an accelerometer). Since you're a ways out from the city, you may want to use a combination of WiFi if they are within a couple miles of the farm, cellular if they're a few miles away but still within LTE Cat 1M range, and LoRaWan if they're a good ways out. (In this particular case we aren't outfitting the horses with satellite connectivity). WiFi is free, LTE is fairly inexpensive but reliable if within range, LoRaWan is lower reliability but can be used in a meshing setup. Each one has a different frequency band: 2.4GHz for WiFi, maybe 1.9GHz for LTE, and 900MHz for LoRa.
Let's say you invent such a thing, and now horse lovers around the world are clamoring, nay, DEMANDING you sell them your ingenious invention. With GSM, you can easily deploy worldwide with a single design. But with LTE you'll need to make sure each country you ship to can support the cellular module you've chosen. You may end up swapping similar-package-but-different-frequency-band modules for Europe, North America, Asia, Africa, etc. However, you can stick with that same Taoglas antenna!
These antennas are SMT, pick-and-place friendly, so you can use them in plastic enclosures without knobbly external antennas that catch on things. This allows for very slim, compact designs like this Taoglas EDGE module (https://www.taoglas.com/product/ec55-system-on-module/) or waterproof/weatherproof cases. Picking the right antenna will get you better battery life, better range, and faster response times for 'free', so its important to give one with the best gain you can get.
Best of all, the full range of different Taoglas antennas, including the Taoglas WARRIORX PA.760.A (https://www.digikey.com/short/td8wnqd2), are available on Digi-Key for immediate shipment. Order today and you can be blasting with a bandwidth wider than a horse's butt by tomorrow afternoon!

We got a few samples of these very nifty USB C cables - there's a Type C plug on one end and a DC 2.5mm/2.1mm on the other. On the plug is etched a voltage and current range. inside is a USB C PD chip that negotiates to try and get the selected voltage and current out of a USB C power plug with Power Delivery management, and it works! we got 9V, 12V, 15V and 20V cables and tested it with our 3A test load and the cables had almost no drop. these could be super handy for getting significant power from USB C without having to do the noodling of programming or configuring a PD chip. coming soon to the adafruit shop!

We got some samples of Nanjing Qinheng Microelectronics http://www.wch-ic.com/ CH9102F and it's pretty much a drop in replacement for Silicon Labs https://www.silabs.com/ CP201x USB to serial chips. A new driver install is needed but its the same pinout and package - great for us because we're having difficulty getting CP210x chips in enough quantity to keep our stock of ESP32 Feathers available for sale! We tested it on Windows and a Mac M1 to make sure uploads at 921kbps still work - next up we'll see if it works on Linux. If so, you may see some of our boards come with this chip in the adafruit shop soon.

@Brooklyn Botanic Garden #adafruit #cherryblossom #Brooklyn
On this week's Desk of Ladyada we're celebrating spring - the tulips and cherry blossoms are blooming all over NYC this weekend. We took some cute spot-color pictures with the KB2040 for an upcoming freebie promo. We also got some samples of CH9102 which work great as replacements for CP210x which is good because we've had some difficulty getting the chips we've booked on allocation. We also found a very nice USB PD sink chip that has I2C and pin-select for voltage and current, and designed a breakout!

This week's EYE ON NPI is getting fit and staying healthy, with ams OSRAM's AS7038RB Biosensor Solution with Embedded ECG Channel (https://www.digikey.com/en/product-highlight/a/ams/as7038rb-biosensor-solution). This all-in-one biological sensing and health sensor combines an optical PPG (https://en.wikipedia.org/wiki/Photoplethysmogram) pulse oximetry sensor (https://en.wikipedia.org/wiki/Pulse_oximetry) with electrical ECG front end (https://en.wikipedia.org/wiki/Electrocardiography) as well as skin temperature reading with a low cost NTC thermistor, and conductivity - a.k.a GSR - so you can get a lot of heart and blood health information in one convenient package. This is very nice and cost-effective as usually there's one sensor to manage the optical blood-gas sensing and one to do the electrical heart activity sensing and maybe other sensors for skin temperature and conductivity. However, for telemedicine or self-monitoring, it might be beneficial to see the electrical activity waveforms as well as the SpO2 measurements since they can signify different health issues.
Even though we are highlighting the AS7038RB (https://www.digikey.com/short/mjq0vjrn) we also want to point out the AS7030B (https://www.digikey.com/short/z308w2wr) which is a 'modularized' version of the 'RB but with a plastic body and three emitter LEDs for an even simpler installation. We're particularly fond of any PPG sensor that has both the emitter and detector diodes built into the package, it makes sourcing and tuning a lot easier!
With the proliferation of smart watches and wristbands, many are now including optical sensors on the bottom - and this sensor is a great way to add that capability to your design without a ton of extra components or work. Pulse oximetry, especially, has become an essential home measurement for folks who have COPD or have tested positive for COVID as low blood oxygen and high pulse rate indicate cardiovascular damage that sometimes the patient doesn't even notice (https://en.wikipedia.org/wiki/Silent_hypoxia). A full time wearable PPG using the AS703x would be great for detecting hypoxia even if the patient forgets to check their pulseox.
This sensor comes jam packed with many built in filters and configuration registers to tweak the LED current, optical sensor gains, low pass, high pass, offset and drift reduction. This is usually the hardest part of getting PPG/ECG data in a pure-digital system: filters and offsets can be easy to implement in analog-land but annoying for a microcontroller to continuously calculate while also trying to stay in a low power mode. Instead, that work is done so that clean data can be read from I2C directly when ready.
There's also a Feather-friendly eval board available for purchase (https://ams.com/as703x-eval-kit), with a built in Particle Argon Feather board for fast IoT prototyping using the default ams Windows application. The app lets you tweak and set various values and gives some good starting points, especially for customers with different skin tones!
Sounds great, right? If you wanna pick up the ams OSRAM AS7038RB Biosensor Solution with Embedded ECG Channel (https://www.digikey.com/short/mjq0vjrn) It's in stock right now at Digi-Key, for immediate shipment! Order today and you can be PPG-EKG-GCR'ing to your heart's content (ha!) by tomorrow afternoon.

We've been working on making for QT Py's for various chipsets and we were getting some connection issues on our S3 QT Py. Thanks to unexpected maker, we got a Hot Tip on how they had the same issue but fixed it with some pi network tuning! Tuning for an antenna can take swapping out a range of capacitors to get the best performance. The best way to do that is to get a RF capacitor kit, so you can try lots of different values quickly! Let's find a kit for 0402 sized capacitors that range from about 1 to 10pF and are C0G/NPO precision.

We like to use our Pretty Pins generator to make lovely and accurate diagrams of dev boards. It starts with the Fritzing object (which is generated from the original Eagle files), and then cross references the Arduino and CircuitPython variant definition file to get the true pin names of each exposed pad and signal. Finally it looks up the multiplexing functionality for that gpio pin on the chip in a spreadsheet to generate the lovely label boxes. The pinmux spreadsheet has to be made by hand but we finally got around to doing the massive table used for the SAMD51 so we can now generate Pretty Pins for all SAMD51-based designs. You can see the CSV here https://github.com/adafruit/PrettyPins/blob/main/samd51pins.csv

We were looking at WCH @Patrick_RISCV for a USB to serial chip to replace the CP210x, when we remembered a lot of chatter a few years ago about the CH552 series of ultra-low-cost 8051 microcontrollers with native USB. you can kinda sorta code these with Arduino https://hackaday.io/project/172143-ch55xduino and we thought it could be an interesting QT Py since it has so few pins but does cover the basic use cases: 4 ADC, UART, SPI and maybe even I2C with a bitbang connection? Still, for very very basic USB projects maybe it would be useful, particularly since it has a ROM USB bootloader. Here's a simple design we whipped together. Since there isn't a lot of muxing or IO available, MISO and A2 share the same pin. Some interesting unusual things to watch for: reset is backwards from how we'd expect, and bootloader mode is entered by pulling D+ to 3V? Any CH55x experts out there who want to take a look and see if we got it all wired right? Anything we missed?

This week's EYE ON NPI should be on your radar - it's InnoSenT's 24 GHz IMD-2000 Radar Sensor (https://www.digikey.com/en/product-highlight/i/innosent/imd-2000-radar-sensor) This all-in-one sensor is easy to integrate into your next product and brings high-tech radar sensing to an affordable range.
Radar is literally "Radio Detecting And Ranging" - a way of bouncing 'high frequency' electromagnetic waves off of objects to detect the reflection. We're familiar with radar (https://en.wikipedia.org/wiki/Radar) in a few contexts: originally developed for military use, it worked great for detecting metal things in the sky (airplanes) as they would approach a city to possibly bomb it. We still use it a lot in military contexts: detecting planes, bombs, boats and submarines. It's also super handy in domestic contexts like air traffic control, if you can detect planes you can verify their positions and make sure each one comes in or out of the airport without collision. Radar is also useful for weather pattern detection (although this sensor isn't good for that purpose, just a fun fact for you to know)
Another common purpose for radar you're probably familiar with is the dreaded speeding radar gun (https://en.wikipedia.org/wiki/Radar_speed_gun) a small-enough-to-be-handheld radar device that can be pointed at a car to determine its speed without requiring a difficult-to-calculate "time between two points" measurement. These reliable devices (which apparently now are replaced with LIDAR based ones!)
Now, most folks who have used IR sensors, Time of Flight, or sonar sensors can understand how to detect an object by counting the delay between sending a signal vs when its received and dividing by the wavelength. How can you determine velocity - normally you'd need to detect location twice, then determine the time between the two locations whereas radar can do it one measurement. This is thanks to the 'Doppler effect' (https://en.wikipedia.org/wiki/Doppler_effect) the same scientific principle that causes ambulance sirens to be higher pitch as they approach and lower pitch as they drive away from you due to the 'bunching up' of the waves as the wave source moves. Likewise with Radar, the frequency will shift slightly depending on the speed of the object, which can be detected by calculating the minute variation in frequency.
Radar sensors are often used in similar cases as IR, ToF, sonar or LIDAR sensors: for detecting objects or motion or distance. Compared to IR, Radar will give you a much longer range and will work with a wider range of objects without being affected by ambient light, object color or shininess. Compared to ToF you'll get velocity, long range. Sonar is longer range than IR or ToF but has a wide spread. LIDAR is very comparable but is new and more expensive - Radar is easy to implement and low cost by comparison.
And this Radar module is particularly easy to use because unlike many cheap modules that only give you a pulse signal that has to be massaged and measured to determine object distance and/or speed, this one has an FTDI-cable (https://www.digikey.com/en/products/detail/adafruit-industries-llc/70/9092299) compatible UART signal out. Simply provide 5V power and you'll get 250 kbps TTL signal out with a listing of objects, distances and velocities. This makes it trivial to integrate with any computer or microcontroller.
The InnoSenT’s 24 GHz IMD-2000 Radar Sensor (https://www.digikey.com/short/40wz7zdd) is the easiest to use Radar sensor we've seen and it's in stock now, for immediate shipment from Digi-Key! Book it today and you can be radaring, object counting, distance measuring, velocity-finding and more by tomorrow afternoon.

This weekend we took a day trip out to NJ to visit the InfoAge / Camp Evans historical district in Belmar NJ. This collection of buildings is on a former defense site on the coast and is both host to the VCF East festival AND has a ton of really cool museums and historical artifacts including an epic vintage radio/television museum, an amazing working historical computer collection, maker space, a massive military jeep and tank collection, and more! We took over 250 photos of many of the interesting things we saw. We also got one of the Ruiz' Bros CM-2 Pi/Pico case with LEDs to show off, a great built to honor a lovely historical computer.
The Great Search - 0402 Size RF Capacitor Kit for Antenna Tuning https://www.digikey.com/short/5bttfhdm
We've been working on making for QT Py's for various chipsets and we were getting some connection issues on our S3 QT Py. Thanks to unexpected maker, we got a Hot Tip on how they had the same issue but fixed it with some pi network tuning! Tuning for an antenna can take swapping out a range of capacitors to get the best performance. The best way to do that is to get a RF capacitor kit, so you can try lots of different values quickly! Let's find a kit for 0402 sized capacitors that range from about 1 to 10pF and are C0G/NPO precision.

This week we're continuing on last week's RS-232 FeatherWing and looking at maybe making a multi-use design. We've also had requests for an RS-485 FeatherWing and perhaps we can design something that could be used for either. We've used a 'MAX232'-like before, but for RS-485 we'll need a different kind of chip, one that does a differential transmission. Let's see what's available and how we would wire it up!

https://gothamist.com/news/now-open-a-two-acre-rooftop-park-atop-manhattans-pier-57
We have been on the lookout for a Sony Flamingo - a very retro-futuristic turntable that can play singles or LPs using a funky minimalist design. It is a gorgeous piece of machinery. Meanwhile, we know folks like using a Raspi to make a 'pihole' ad/malware blocking DNS server but pi's are hard to get, so we looked at turning a Feather ESP32-S2 TFT into an 'esphole' and found a great project to fork off and tweak https://github.com/s60sc/ESP32_AdBlocker
We've added mass storage config, and a TFT display to show the IP address and status. We also threw together a quick breakout for a very nice precision magnetometer the MMC5983 https://www.digikey.com/short/m43v5mtj and we're taking a peek at an interesting USB PD chip the HUSB238 which has a resistor set for current and voltage as well as I2C configuration port!

we have a spaceball 2003, a 1990's-era 3D interface device, and we tasked ladyada with getting it working! it has a 2.5mm DC jack + RS-232 cable for data, and its encoded in binary data with a fairly simple protocol - lots of data here: https://spacemice.org/index.php?title=Spaceball_2003 ! with a little pyserial work, we got the button presses and XYZ vector data out. code is posted in this gist https://gist.github.com/ladyada/f9f5ab3a4ee7a73337d251e267038de9 . we were thinking we could make this into a USB HID device with circuitpython next! but first we'd have to have a way to convert rs-232 to ttl.

The ESP32-S3 has native USB like the S2 and adds a dual core Tensilica, Wifi AND BLE plus extra SRAM so its a great upgrade. We worked it into a QT Py format which will make for great lil IoT projects. (check out the Feather we are stocking too https://www.adafruit.com/product/5323) we like our panelization technique for boards, with half route and half v-score, it makes it fun and easy to pop off the boards from the railings and test. The raspi here is uploading code via esptool, checking the GPIO and then verifying the wifi strength is as expected. We'll get the first few panels tested and then we can stock this qt new board :)

This week's EYE ON NPI will woo you like a period romance show - no, we're not talking about Bridgerton, this is a different kind of Bridge! We're highlighting NXP's SC18IM704 UART to I²C-Bus Bridge (https://www.digikey.com/en/product-highlight/n/nxp-semi/sc18im704-uart-to-i2c-bus-bridge). This is a chip or module that will let you take an existing system with RS-232 or UART Serial and wedge in I2C support. Handy for desktop computer systems that just need to integrate a single sensor or control in userspace or embedded computers without extra GPIO: having user-space support for I2C, ADC, DAC or SPI is rare if you don't happen to have a BeBox (https://en.wikipedia.org/wiki/BeBox) but you can get almost any kind of device connected if you've got I2C!
These sorts of bridge devices could also be super useful during the chip shortage (https://en.wikipedia.org/wiki/2020%E2%80%93present_global_chip_shortage) - which we think will continue through until 2024 - where you have a design that has the right matching peripheral set, and then at the last minute, a part can't be sourced and you end up needing to re-spin the design. You may be able to get a similar spec part but...it doesn't have UART, only I2C, or SPI, or any mix-and-match combination of the three! For that reason, there's actually a couple different bridge chips that NXP makes (https://www.nxp.com/products/peripherals-and-logic/signal-chain/bridges:MC_50962)
The SC18IM704 (https://www.digikey.com/short/j242d1nm) has a single UART in and an I2C output, with 8 additional GPIO pins that can be handy for IRQ or busy pin reading, or for resetting pins or changing address selects. Commands are sent as bytes, and the user can initiate I2C start/stop, then read/write as well as setting GPIO direction, pull and value. Since NXP now owns Philips who wrote the I2C specification, (https://www.i2c-bus.org/specification/) you can be sure that this chip will work well with any I2C-standard sensor or expander you could find.
If you aren't integrating the chip, like say you have a computer board or other industrial device and you just want to get started fast, you can pick up the NXP SC18IM704-EVB eval board (https://www.digikey.com/en/products/detail/nxp-usa-inc./SC18IM704-EVB/15777144) which provides an RS-232 port and plug and play headers with 3V logic and 5V compliance.
Like many new product introductions lately, there were not many chips released in the initial stock and they're currently sold out! However, the NXP SC18IM704 UART to I²C-Bus Bridge (https://www.digikey.com/short/j242d1nm) is a stocking part on Digi-Key and a few thousand will be shipping in 2 months, so you can book an order today and have it send to you as soon as its available!

Learn Guide for ESP32 V2 Feather Huzzah https://learn.adafruit.com/adafruit-esp32-feather-v2
It’s designed for Low power usage so you can use a lipoly battery in deep sleep. It features the ESP32 Pico module, so you get extra space for pin labels and mounting holes!
With STEMMA QT, you can just plug in your favorite sensor breakouts and start plotting data. It’s a great way to quickly get your IOT projects up and running.
You can use it with Arduino IDE just like other ESP32 boards - with the extra flash and RAM, even big complex projects are a breeze.
With WipperSnapper you can easily make IOT projects without having to write any code! Just install the firmware with a chrome based browser, now your Feather will appear in Adafruit.IO automatically.
ESP32 V2 also has MicroPython support so you can write python code and libraries to create your IOT Projects.
Follow along with the Adafruit Learn Guide to install and set up your Feather ESP32 V2.

To get this nifty Spaceball user interface working, we're using a USB to RS-232 adapter cable. But for the next step in this project we'll want to use a Feather board. In order to connect to the DE-9 port safely, we need to convert the TTL serial on a Feather (0-3V logic) to +-6~10V inverted logic. Thankfully, there are chips that make it easy - they even have built in switched-cap converters to create the +6V and -6V logic rails! Let's find one that we can use to make an adapter FeatherWing with.

Mr Ladyada gave me this funky 3D mouse to play with today - it has a DE-9 plus power supply cable on it, so with a little googling and pySerial hacking we were able to get button and motion data out of it. Next up, we want to design a RS-232 Featherwing to make it easy to attach to these sorts of devices and send/receive data. Even though RS-232 is kinda old at this point, we still see a lot of devices that show up with one of these 'universal' ports! We'll also check out a cute Arduino compatible we got in the mail.

This week's EYE ON NPI is a fusion of form and functionality - it's the MF-LSMF Series High-Power PPTC Resettable Fuse collection from Bourns! (https://www.digikey.com/en/product-highlight/b/bourns/mf-lsmf-series-high-power-pptc-resettable-fuses) These are super-fuses, made of a polymeric material that allows them to be small and thin, but pass large amounts of current, at high bias voltages. With current ranges up to 6A hold (12A trip!) and 33 VDC max voltage, these fuses are burly enough to be used in large LED or motor-driving projects that normally would need a more expensive PMIC or eFuse (https://www.digikey.com/en/products/filter/pmic-current-regulation-management/734) or a non-resettable glass/ceramic fuse. (https://www.digikey.com/en/products/filter/fuses/139)
PPTC stands for polymetric positive temperature coefficient. PTC means that as the temperature rises around the resistor, the resistance also rises. There are linear kinds of PTC's that can be used for temperature measurement (silistors) but these are ones that have a non-linear rise (switching type). The resistance actually starts dipping slowly and then shoots up after reaching a certain, adjustable, temperature called the Curie point.
When current starts flowing through a PTC, the resistance dips a little, and its quite low to start, usually in the milli-ohm range. Once the current increases a certain amount, the wattage through the PTC's resistance (P = VI = RI^2) sets the dissipating heat, the temperature rises, and the Curie point is reached. Then the resistance shoots up to 'open' the circuit, essentially disconnecting the two sides of the circuit since the resistance is in the 10's or 100's of Kohms. However, now the current has dropped and so the power dissipation goes down to zero. After a few seconds or minutes, the material cools down past the Curie point and the resistance allows current through again. (This is why, if your USB port or random electronics product stops working, it does work to unplug it, wait a few minutes, and then try again.)
Compare this with classic 'wire' fuses with ceramic or glass or thermoplastic bodies, and a thin wire inside. When too much current goes through the fuse wire, it gets hotter and hotter and eventually melts, cutting off the load from the source voltage (https://flickr.com/photos/shardayyy/8028645604/) But it doesn't self 'heal' - it's a one time thing only! Bourns has adjusted the Curie point on each fuse to match a different voltage and current limit, and they can be trusted to quickly trip when the current goes over the rated limitation.
PPTC's are inexpensive, easy-to-use, and add quick protection to your products - you may have seen them on many of our own designs such as the Adafruit Metro which as a simple 5V 500mA one (https://www.adafruit.com/product/2488). Now with these wide current and voltage ranges from Bourns, there's no reason not to add one! A wide range of Bourns MF-LSMF Series High-Power PPTC Resettable Fuses (https://www.digikey.com/en/product-highlight/b/bourns/mf-lsmf-series-high-power-pptc-resettable-fuses) are in stock now at Digi-Key for immediate shipment. Order today and you can keep your high-power design safe and sound by tomorrow afternoon

We're checking out a few samples we got last week including this totally adorable traffic light for architectural models. It has a common anode and three cathode wires, that make for easy control. The wires are super skinny but we poked em into a solderless breadboard to make this demo in Arduino. We also got a 6-pogo-pin clip that could be useful for programming boards that don't need a full jig.

eFuses are a nifty way to protect your electronics from over/under powering - handy for maker electronics AND industrial equipment that needs to keep chugging along no matter what happens to the power supply. We had someone ask us to design a board that would take 4xAA input and give USB output - one way to do that is with a buck-boost converter (which we already have) but maybe we could get away with a lower-cost and complexity design. Instead we'll look for an eFuse that will permit no more than about 5.5V and have reverse current, reverse voltage and under/over voltage protection!

We got a user request today for a board that would convert a Raspberry Pi Pico $4 microcontroller board to use Arduino shields. An interesting idea! Let's go through what we do at the Desk when a new idea like this is presented to gauge feasibility.
The Great Search - 5V eFuse https://www.digikey.com/short/b9c215hd
eFuses are a nifty way to protect your electronics from over/under powering - handy for maker electronics AND industrial equipment that needs to keep chugging along no matter what happens to the power supply. We had someone ask us to design a board that would take 4xAA input and give USB output - one way to do that is with a buck-boost converter (which we already have) but maybe we could get away with a lower-cost and complexity design. Instead we'll look for an eFuse that will permit no more than about 5.5V and have reverse current, reverse voltage and under/over voltage protection!

This week's EYE ON NPI is going with the flow and keepin' everything chill and low pressure with Sensirion's SFM3119 Low-Pressure Drop Flow Meter! (https://www.digikey.com/en/product-highlight/s/sensirion/sfm3119-low-pressure-drop-flow-meter) This sensor is designed primarily for medical use cases - ventilators, CPAPs, oxygen masks, etc., but could also be used for industrial setups where non-toxic gas flow needs to be measured. What's interesting about this sensor is it doesn't use a little fan like the turbine sensors (https://www.adafruit.com/product/5066) we've used before for liquid flow measurements. Instead there's a digital (capacitive?) flow sensor that does not impede gas/air flow. This means it can be used for very low flow rates without interference.
Like many of the sensors we've been investigating lately, there's an integrated analog front end with I2C controller already inside, so no complex calibration or linearization setup is required. There's a simple 4 pin interface with power, ground, SCL and SDA. On GitHub we found a wide range of libraries (https://github.com/Sensirion/?q=sfm&type=all&language=&sort=) for Arduino, Python, and embedded C, to handle the various I2C commands and checksums required.
Data comes out of the libraries as flow rate in slm (standard liter per minute) and temperature. We were able to get our Arduino example with OLED output display working within a few minutes! Given the strong support, low price, and ease-of-use we can recommend this flow rate sensor even for non-medical purposes. While its designed for air or oxygen, it could possibly be calibrated for other non-corrosive gas types.
While we were prepping for this EYE ON NPI, the sensor went out of stock at Digi-Key! But according to the lead time estimate system, more Sensirion SFM3119's will be in stock at Digi-Key in the next month or two (https://www.digikey.com/short/2jcff3qp). You can back-order this sensor or sign up to be emailed when they come back into stock for immediate shipment or notification when the next batch of this popular sensor lands in the Digi-Key warehouse!
Adafruit is currently requiring a verified account with two-factor authentication enabled in order to purchase certain high-demand products, such as Raspberry Pi computers, due to a large number of bot-purchasers making it difficult for Makers and Engineers to order these products.

jepler is working on a Pull Request to FluxEngine to add support for the "a2r" flux format, commonly used in Apple II software archiving. Together with open source passport.py, this can be used to bring a copy-protected floppy disk into an emulator.
This video shows "Pow! Zap! Ker-plunk! The Comic Book Maker!" for Apple 2. Saved in the a2r format by an experimental build of FluxEngine, converted to .woz with passport.py and finally loaded up in the MAME emulator.

We were flipping through a cool old book on how computers were made and there was a section on 'core memory'. This is how data was stored dynamically on computers before capacitive-based RAM. Instead of storing a charge on a transistor's gate, the flip of a ferromagnetic core in a grid could store a single bit. Some folks make core memory for fun now - you just need some enameled wire and miniature ferrite cores! While the ultra-tiny rings of yore are no longer made, you can still get some pretty small toroids. Let's see what's available at Digi-Key!

In this project, we’re 3D printing custom book sleeves.
Guide: https://learn.adafruit.com/3d-printed-book-sleeve
Book sleeves can help protect the binding of a book and illustrate detailed hints about the subject.
The stock detachable covers are usually made of paper.
These 3D Printed sleeves are ridged and help keep the spine of the book in shape. The added dimension can really help to show off the artwork and looks great when displayed on your shelf!

This week was massive in the fabrication dept at adafruit with a lots of revisions that we started a few months ago. Check out https://www.adafruit.com/new/ to see check them out. While this week was busy managing those revs, we're checking out some other sensors that caught our eye for turning into STEMMA QT boards: VL53L4CX (6m range ToF!), ENS160 (AQI sensor), DRV8231 (3.7A H-bridge), and LPS28 (4000 hPa barometer). Mr ladyada also picked up a nifty old book on computers.

New tutorials on the Adafruit Learning System: http://learn.adafruit.com/
This week's EYE ON NPI can make a big difference in how fast you get temperature and differential pressure data into your next design - it's TDK's AVD Series Low-Profile Pressure Transmitters (https://www.digikey.com/en/product-highlight/e/epcos/avd-series-low-profile-pressure-transmitters). They're all-in-one, ready-to-use temperature and pressure modules with ports, analog management circuit and a simple I2C interface that can quickly integrated into any microcontroller or microcomputer product.
These are differential pressure sensor modules: that means they will be able to measure the positive or negative difference between two ports. Very handy when you just need to know how an internal cavity pressure measures up against outside air pressure. A common use case for these sorts of sensors is HVAC systems with filters to keep dust and debris out of the system where it could clog the motors or make air dirty. The filters eventually fill with dirt (https://www.flickr.com/photos/ivydawned/4020166274/) and the HVAC has to spend more and more energy to push the air through the clogged filter. While maintenance staff could check the filters weekly, for a large building that could get very time consuming. Instead, a sensor like this one could measure the differential pressure once a day and notify staff when the change increases past some threshold.
We like the small, fully-integrated design of this sensor. There's a nice plastic enclosure, two barbed ports, and dual JST SH 5-pin (https://www.digikey.com/en/products/detail/jst-sales-america-inc/SHR-05V-S/759884) connectors that can be used for I2C connectivity. These aren't quite STEMMA QT connectors, but we were able to fashion a simple adapter for a demo. The I2C interface is very simple: there's no register map, just read 4 bytes over I2C and perform some simple calculations to determine temperature and pressure. We were able to throw together some Arduino code to read data and display it on an OLED in under an hour.
The sensor comes in three varieties: 1.6kPa, 10kPa and 700kPa ranges (https://www.digikey.com/en/product-highlight/e/epcos/avd-series-low-profile-pressure-transmitters). The code and wiring is the same for all three, you can just change the range multiplier depending on which one you've got. Finally, for fast mechanical integration, there's a well-detailed dimensional drawing and a STEP 3D file with all the elements rendered in color.
While this module is more expensive than a raw analog differential piezo pressure sensor - having the device packaged, linearized and digitized makes it very easy to integrate and install. And you can tell they did a really great job making this a quality sensor module! Best of all, all three versions of the TDK AVD Series Low-Profile Pressure Transmitters are in stock right now at Digi-Key for immediate shipment (https://www.digikey.com/short/90n7wrj5). Take the pressure off of yourself, and order today - you'll be able to add a professional quality, ready-to-install differential pressure sensor by tomorrow afternoon.

Adafruit received a request over email for a 16-Bit resolution DAC to match with the 16-Bit ADC we stock (ADS1115). Not a bad idea! We stock a few DAC breakouts (https://www.adafruit.com/?q=dac&sort=BestMatch) but they are either 8-bit or 12-bit MCP47xx's, and there may be times you really want something a little smoother for precision control. We're going to try and make something with Stemma QT so I2C control.

Music by Bartlebeats https://soundcloud.com/adafruit
we spent today working on a ESP32-S3 feather. you may be thinking "hey wait didn't you already design one?" yep! but we had a hardware bug that increased deep-sleep power, and so we wanted to revise the ESP32-S2 feather first to fix it since the PCBs for the two designs are shared. now we have the new ESP32-S2 in the shop with the fix https://www.adafruit.com/product/5303 so we can respin the S3. even better, Espressif has started adding S3 support in a branch so we were able to test the GPIO, I2C, UART, NeoPixel, low power, and WiFi capabilities successfully. We've got a PR open to add this new board - it's very exciting! https://github.com/espressif/arduino-esp32/pull/6450 This board uses the only S3 mini module available right now, with 8 MB of Flash and no PSRAM. however, there's more SRAM on the S3 than S2 so its still very usable. when the PSRAM-containing mini module comes out we'll make a version with that too.

This week we've been working on more and more revisions and also trying to get some older designs out the door. For example, we've got some ESP32-S3 feather and QT Py designs that we didn't release due to some errors and also S3 support in the world wasn't quite ready. But with our revised S2 design done, we swapped out a board on the panel with an S3 mini module and there's even Arduino support in espressif's esp32 branch. Let's maybe go through how we add support for a new ESP32 board together. Also, a transparent OLED sample arrived, it looks very cool!

New tutorials on the Adafruit Learning System: http://learn.adafruit.com/
We're inclined to think you'll love this week's EYE ON NPI, since it's the Murata SCL3300 Series 3-Axis Inclinometer (https://www.digikey.com/short/9pqpb9z3), a really unique and useful sensor that can be very useful for industrial and robotic applications. Inclinometers measure...incline! (https://en.wikipedia.org/wiki/Inclinometer) That is, the angle of tilt of the sensor and the platform it's placed on. This is useful when you want to make sure something is perfectly straight or flat with respect to the center of Earth's mass. If a robot or piece of construction equipment isn't perfectly level, errors can build up and construction projects can end up with big flaws, gaps or repairs. Not good!
Now experienced engineers (including ourselves, before we researched this part) may be wondering: wait, if you're measuring tilt with respect to the earth, why not just use an accelerometer (https://en.wikipedia.org/wiki/Accelerometer)? Accelerometers measure acceleration, and gravity is an acceleration force everything on Earth is affected by, so you can easily do some math on the number of g's measured by an accelerometer and convert that into tilt with a little math as shown by this detailed ST app note (https://www.st.com/resource/en/application_note/an4509-tilt-measurement-using-a-lowg-3axis-accelerometer-stmicroelectronics.pdf)
So why have a special sensor called an inclinometer, and why does it cost much more? Well, accelerometers can be used for rough tilt calculations, but they're not really designed for it. They tend to be used for 'gross motion detection' like taps, jerks, big angles. For that reason many everyday accelerometers are maybe 10 to 12 bits of precision (https://www.adafruit.com/?q=accelerometer&sort=BestMatch) and +- 2g to +-16g. That's fine for motion detection, but not precise enough for minute changes in tilt, where only a few mg of change in gravity can affect the angle. So you can think of an inclinometer as a special type of accelerometer, with very low g rating, and very very high accuracy (how close the reported value is to reality) and high precision (how many digits you can squeeze out of the measurement)
So for example, a common accelerometer may have, at +-2g a precision of 1mg per LSB, whereas the SCL3300 in inclination mode has a precision of 12000 LSB/g (which is 12 LSB/mg and 0.08 mg/LSB). The noise density on a common accelerometer is about 220 μg/√Hz, on the SCL3300 is as little as 15 μg/√Hz The temperature and offset stability are also going to be much better. Basically, its very very precise, but not designed for moving fast - that's what a high g accelerometer would be for!
For detection of small changes, or small angles, the Murata SCL3300 Series 3-Axis Inclinometer (https://www.digikey.com/short/9pqpb9z3) will do the job much better than an accelerometer, with a simple SPI interface that will integrate quickly with any microcontroller or microcomputer. We especially like that the SPI interface has CRC and error monitoring, important for critical installations. And for such a precise sensor, the price is very good as well! The sensor is available on an easy-to-use eval board (https://www.digikey.com/en/products/detail/murata-electronics/SCL3300-D01-PCB/11618562) if you want to start prototyping fast. Both sensor and eval board are in stock right now for immediate shipment from Digi-Key. Order today and you'll be inclinating (that's a word right?) by tomorrow afternoon.

Jeff Epler recently contributed code to FluxEngine making it possible to write Apple II disks using a FluxEngine-compatible floppy interface, such as the prototype Adafruit Floppy board.
In this demo, jepler uses a standard PC 5.25" floppy drive (TEAC model FD-55GFR) connected with the Adafruit Floppy board to write a floppy disk with a classic educational game downloaded from archive.org: Number Munchers.
Previously we've demonstrated how using the Adafruit Floppy interface you can read and write disks for PC and Commodore 64, and also read disks for Mac including crunchy old 400kB and 800kB floppies, which PCs have traditionally been unable to read.
Want to try your hand at Number Munchers and prove that you know what a prime number is? You don't need an Apple II, just play it in an emulator: https://archive.org/details/MECC_A170_v10_4amCrack

This week's EYE ON NPI is a gaze into the duality of man! Wait, no, it's a gaze into the dual-concentricity of this fascinating new rotary encoder: the Bourns PEC11D Series Dual-Centric Rotary Encoder with Momentary Push Switch (https://www.digikey.com/en/product-highlight/b/bourns/pec11d-series-dual-centric-rotary-encoder-with-momentary-push-switch).
We have covered rotary encoders and switches on EYE ON NPI before (https://blog.adafruit.com/?s=eye+on+npi+rotary) so you may be familiar with them. Rotary encoders are a popular user interface element that engineers use to add a tactile increment/decrement control. We find they’re much more intuitive to use than touch screens, especially when you want to increase or decrease a value precisely: it's a lot easier to twist the knob by one detent than it is to press a touch screen once. Rotary encoders can also be used hands-free or when observing some output because the tactile feedback is strong.
The most common rotary encoders used for user input are mechanical style, usually with detents. They can be ring-style like the famous iPod Clickwheel or knob style. These are two mechanical rotary encoders in that there is a little leaf spring connected to the knob and the “common” pin, and the body has a metal-cutout piece, that when rotated connects and disconnects the two side pins from the common. The two pins pulse high and low to indicate motion and direction. Usually two interrupt pins are connected to the rotary encoder to catch the pulses and track the counter increment or decrement.
Say you have some product you're designing and you want to have two encoders in one, say because you want 'rough' and 'fine' adjustment. You could use one encoder and have the button state determine what mode the encoder is in. (https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Rotary_Trinkey/CircuitPython_ColorPicker_Example/code.py) However, there may be a situation where you want to use that button for entering the new setting. Or if you have a very space-constrained interface, and you can't fit two side-by-side.
That's where the Bourns PEC11D (https://www.digikey.com/short/013h5701) will come to the rescue! This encoder has two (count 'em two) rotary encoders in one package. By turning the outer or inner part separately you can control two electrically separated rotary encoders, and there's also a push-button input. You'll need to mould or machine a special knob to allow selection of either half, but most folks end up with custom knobs rather than off-the-shelf for a final product anyways.
We wired this cute li'l guy to an Arduino and ran a rotary encoder demo that was expecting two encoders and it worked like a breeze - just the way you expect! This unique user interface element definitely solves an existing problem and Bourns is famous for their high quality encoders, so you know it will last and work well in your product design.
The Bourns PEC11D (https://www.digikey.com/short/013h5701) is in stock now for immediate shipment from Digi-Key. Order today and you'll be concentrically rotating by tomorrow afternoon!

One part that's been holding up a lot of our products from staying in stock is the LIS3MDL. Originally this was a $1 triple-axis magnetometer that paired well with IMU chips for making full-fusion orientation sensors. Now they're going for $20 on the gray market with an estimated ship date of 2059 (e.g. 'who knows').
Since we were out of IMU chips for a while, we were OK waiting. But now we've got some in stock and with no magnetometer shortage end in sight, we're thinking of just replacing the LIS3MDL. Especially since the magnetometer is not the most sensitive sensor in a 9-DoF (that would be the gyro). Let's identify a sensor with about +-20 gauss (+-2 mT) range, I2C interface, and affordable enough so we don't have to change our prices.

"Circuit Garden celebrates our electronic culture and invites us to contemplate nature – specifically human nature in symbiosis with machine intelligence. Artist Kelly Heaton presents a large-scale circuit board in the form of an artificial lawn that is “planted” with plush sculptural electronic devices. The work evokes a playful garden, or a vintage circuit board that has been enlarged to human scale. Situated in the landscape of Circuit Garden, viewers will discover smaller functional circuits that mimic animal behaviors, such as birdsong and chirping crickets. As the viewer approaches the installation to investigate further, Heaton’s analog electronic designs generate these naturalistic sounds in real time. The sonic landscape of Circuit Garden is thus brought to life by electric vibrations of artificial origin and not recordings of real birds and crickets, as one might expect." STATEMENT BY KELLY HEATON: "“Electronic technology is profoundly shaping our world. Many people are symbiotic with their smart phones and digital presence. Artificial intelligence is growing smarter, and our concept of “nature” is being radically transformed by engineering. Electricity is the most important invention since the discovery of fire. Yet, the art of electrical engineering is not well understood or practiced by people outside of the scientific community. I would like to invite everyone—not only engineers—into a conversation about electronic culture, nature, and the rise of machine intelligence. While most artists work with digital media, I focus my creative practice on electronic hardware because circuits are the physical body without which there would be no digital media. Like a biologist studies animals, I study circuits to understand the physiology of intelligent machines. I am inspired by Nikola Tesla’s statement, “If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.” My art explores these concepts literally in the form of circuits that vibrate in naturalistic patterns. Circuit Garden pays homage to electrical oscillation, specifically to the astable multivibrator, which is my favorite method to generate life-like waveforms.”" About the artist: Kelly Heaton is a mixed media artist who believes that electricity is the most important medium of our time. She uses circuits to explore the “spark of life” in biological organisms as well as machines, acting as a techno-spiritualist to portray the immaterial character of her subjects. Heaton’s art has been featured in the United States and internationally, including the ADAA Art Show, New York, NY; The Science Gallery at Trinity College, Hartford, CT; the DeCordova Sculpture Park and Museum, Lincoln, MA; and three solo shows at Ronald Feldman Fine Arts, NewYork, NY. She is the recipient of grants from The Peter S. Reed Foundation, Creative Capital, LEF Foundation, Council for the Arts at MIT, and the Jacob K. Javitz Fellowship Program. She won the L’Oreal Promotion Prize in the Art and Science of Color for her research with physical pixels and has been awarded residencies at Otis College of Art and Design, Los Angeles, CA; MIT Center for Advanced Visual Studies, Cambridge, MA; Duke University, Durham, NC; Tortuga Escondida, Akumal, Mexico; and Art Interactive, Cambridge, MA. Heaton received her BA from Yale University and her MS from MIT.

This week we spent a lot of time on revisions! This means we're not able to spend as much time on new products - but it's important to make sure existing customers can keep using our parts. For example, the Ultimate GPS USB board got a respin https://www.adafruit.com/product/4279 to move to the CP2012N and also USB C. We have a few more boards to go for the CP210x revisions. We also decided to revise our PCF8523 breakout - historically we've used the SOIC-8 version, but now we may only be able to get the HVSON-8 version for a few months. Since we can redesign the PCB to use either, we're making a 'flip flop' design. Finally, ESP32 QT Py got fabbed, but we're having issues during test. We think it could be due to the antenna being too strong and interfering with the chip. We could redesign this for uFL connector change the pi-network values to reduce the signal strength a bit. We also got our FLIPPER ZERO https://flipperzero.one/ this week, this adorable mammalian engineering multi-tool has a lot of RF and hardware interfacing built in and it looks great!

This is going to be our first RISC V based dev board, and isn't that something to celebrate? It's a QT Py based on the ESP32-C3 which is a WiFi + BLE chipset with RISC V instead of tensilica core. This chip is a little new, but it does seem to have fairly good Arduino support, we're able to do WiFi tests and thankfully someone sent us a patch for NeoPixels so that's glowing as well. This chip has a built in USB-to-Serial converter (not native USB!) so there's a ROM bootloader, great for beginners because its not brickable. There are not a lot of pins on the C3, its a very minimal chip, so the QT Py is actually a perfect format. this particular board is the first off the machine line this morning, so it'll be in the shop soooooon https://www.adafruit.com/product/5405

We use the AP3429 in one of our little power breakout boards. It's a small but strong adjustable buck converter with 2A internal switch, 1MHz frequency, and an easy layout. It's also really affordable! As you may be guessing, it's very unavailable right now, with lead time into 2024 (!)
We'll book the order, but in the next two years we should probably have something else available. We'll show you how we searched around to find an in-stock alternative that requires minimal board changes with same or better performance.

This week's EYE ON NPI is from a supplier that will challenge your expectations! It's Challenge Electronics' IP68/IP65 Waterproof Battery Holders (https://www.digikey.com/en/product-highlight/c/challenge-electronics/ip68-ip65-waterproof-battery-holders) A series of durable, waterproof battery cases that will do great at powering your board even in intense dusty and wet conditions!
Challenge Electronics’ IP-rated battery holders provide a low-profile form factor with a watertight seal. Designed for AA and AAA batteries, these holders feature a sleek and easy-to-integrate design ensuring waterproof mounting under the harshest environments to save time in the design cycle.
A lot of electronic devices these days are designed to be sealed plastic enclosures (https://www.ifixit.com/smartphone-repairability) - and if they are battery powered, the battery is a LiPoly that is tucked inside and recharged. But there's a lot to be said for the common AA and AAA batteries. These are available anywhere around the world, instantly recognizable, and come in various temperature grades and recharability. For user-or-field replacement, or in use of extreme temperatures, they've still got a place in product design.
The down-side is that battery cases (https://www.adafruit.com/product/4779) are often plastic-retained clips that allow dust, humidity, and spilled-diet-coke in, which can cause icky corrosion to the steel or tin terminals. This Flickr image (https://www.flickr.com/photos/sometoast/3242192055) shows a similar self-corroding affect, but having dampness won't help! Challenge's battery holders are compact, but have 4 screws for secure closure and a built-in gasket that will get you IP65-level sealing (https://en.wikipedia.org/wiki/IP_Code). That means fully dust-tight and water-proof to jets of water. Note this doesn't mean you can dunk it underwater - for that you'd need IP67 or IP68 - these are better for outdoor use or in some industrial settings where there may be liquids flying around.
Challenge Electronics makes Waterproof Battery Holders (https://www.digikey.com/short/8nw43fr8) in three varieties, with AA and AAA sizes. All have the same IP65 rating. If we had to pick one, the 3xAA will give you a good 2500-4000mAh and 3.6V to 4.5V nominal, great for powering a 3.3V LDO project, and AA's are the most common battery. All three types are available right now at Digi-Key for immediate shipment. Book and order today and it will ship immediately so you can have it in your hand tomorrow afternoon.

The Allwinner F1Cx00S series of chips are famous for being "$2 linux-on-a-chip" with DRAM built in - all you need is some passives, a crystal, and SPI NOR flash memory to have a miniature booting linux board. It's not very fast, and it's not very powerful but maybe we could run minimal python scripts on it? we've never used this chip but we used to noodle with openwrt and this seems kinda similar. we couldn't find any open hardware designs so we're drafting up the schematic - hopefully get all the wiring for this 88 pin QFN right :) anyone use this chip before?

The non-TFT version of the ESP32-S2 Feather has been out of stock for a few weeks because we made a design error in rev B and want to fix it before putting back in the shop. We used a P-Channel FET to enable/disable the Stemma QT / I2C power but kept the pullups connected to 3.3V (this was on purpose because the onboard LC709 battery monitor is powered from the battery and this would let you read the battery state without having to enable the I2C power). when a bunch of QT sensors get attached, the leakage from the pullups turns into quite a power sink. for example, here we have 4 I2C devices on the bus and you can see the 'deep sleep' current is a whoppin' 700uA! no good...by switching to a separate regulator and connecting the pullups to the regulator output we get a cool 70uA as we expect. now we can send off this pcb to get this popular feather restocked - sign up at https://www.adafruit.com/product/5000 to get notified!

For our Atari Video Music machine mod, we want to add an S-Video output port. S-Video splits the signal from NTSC into chroma and luma, so the signal tends to be clearer and more stable. Thankfully, the chip in the AVM gives us the chroma and luma on separated pins, so we just have to wire them up to a standard S-Video connector. Let's see how we can find one that will perfectly fit on the AVM without any drilling or gluing!

Music by Bartlebeats https://soundcloud.com/adafruit
We had been working on a lot of camera support for CircuitPython. We're getting back to that project now with an all-in-one DIY camera board with an OV5640 camera module and an ESP32-S2. You really do want PSRAM to buffer large images like 1440p JPEGs for saving to disk. One thing that we bumped into is that SD cards can be very finicky when initialized into SPI mode on a shared bus, but we found a way around it!

jepler ended the week on a high note, getting the motor of an Apple ][ floppy drive moving back and forth with CircuitPython! It's part of our quest to make Adafruit_Floppy work with non-PC floppy disk drives.
The simple code making this happen can be found in a GitHub gist: https://gist.github.com/jepler/16cdb13d8c3298c392d789772a56d177
For this step, +5 and +12V supplies are required, coming from an ATX power supply. The reading circuit requires an additional -12V supply just to spice things up. After that, we'll see what else is needed to start reading and writing flux in these drives.

This week's EYE ON NPI comes in right under the wire...the one wire! It's Maxim's MAX31888 high-accuracy 1-Wire sensor (https://www.digikey.com/en/product-highlight/m/maxim-integrated/max31888-0-25-c-accurate-1-wire-temperature-sensor) with 0.25ºC degree accuracy. This is a lovely little upgrade to the extremely popular DS18B20 (https://www.digikey.com/en/products/base-product/analog-devices-inc-maxim-integrated/175/DS18B20/118476) series of 1-Wire temperature sensors, but with a smaller body and better accuracy - the DS18B20 has at best ±0.5ºC in comparison.
The MAX31888 temperature sensors will keep your temperature logging system fresh and secure, and best of all... They're in stock right now at Digi-Key! Order both MAX31888 sensors (https://www.digikey.com/en/products/detail/analog-devices-inc.-maxim-integrated/MAX31888ALT/15792903) and the eval board (https://www.digikey.com/en/products/detail/analog-devices-inc.-maxim-integrated/MAX31888EVSYS-/15792904) for immediate shipment, you could have them in your hot lil hands tomorrow afternoon!

This week's search is going to be for an LCD driver chip. We've never actually worked with raw LCD elements, but if you do need to use one, you'll quickly note that they're a bit odd to work with and require an 'AC'-like waveform and constant refreshing. They're also very susceptible to ghosting. So let's identify a chip - ideally SPI or I2C - that will do all that drive control for us!

This week we worked on some upcoming new products, including the Feather ESP32 V2 which we listed in the shop in prep for stocking next week. it's a full refresh of the Feather ESP32 and we even got low power in deep sleep - down to 70uA! we also got some LCD samples in the post and had a fun time learning how to drive these with GPIO pins on a microcontroller. finally, foamyguy threw together a little project to make a pyportal into a little audio player and we'll check that out. i've been meaning to redesign the pyportal with an esp32-s3 and this project is sort of inspiring me to get on with it.

when we have a brand new board, we do a lot of checks to make sure that the first panel is right because if there's one thing that makes mistakes very quickly - its a mis-programmed pick and place! this is the time to check the right part, orientation and any placement offsets that need correction. this panel looks good and after it goes through the oven we'll do a first-article inspection with the tester before we let'er rip! this board is the new Feather ESP32 V2 which is a big update to our classic Feather ESP32 but with Stemma QT, NeoPixel, extra button, and a lot more FLASH and PSRAM. we think it'll be really popular!

This week's EYE ON NPI is gonna spin you right round, baby, right round like a record player - it's C&K's ENC Series Optical Rotary Encoder Switches (https://www.digikey.com/en/product-highlight/c/ck-components/enc-series-encoder-switches) a high-reliability encoder with strong detents, that's great for medical and industrial equipment, automotive, and more, where longevity and reliability is important.
Rotary encoders (https://www.digikey.com/en/products/filter/encoders/507) are a popular user interface element that engineers use to add a tactile increment/decrement control. We find they're much more intuitive to use than touch screens, especially when you want to increase or decrease a value precisely: its a lot easier to twist the knob by one detent than it is to press a touch screen once. Rotary encoders can also be used hands-free or when observing some output because the tactile feedback is strong. (https://www.digikey.com/en/articles/a-designers-guide-to-encoders)
The most common rotary encoders used for user input are mechanical style, usually with detents. They can be ring-style like the famous iPod Clickwheel (https://support.apple.com/en-us/HT204217) or knob style. These are two mechanical rotary encoders in that there is a little leaf spring connected to the knob and the "common" pin, and the body has a metal-cutout piece, that when rotated connects and disconnects the two side pins from the common. The two pins pulse high and low to indicate motion and direction. Usually two interrupt pins are connected to the rotary encoder to catch the pulses and track the counter increment or decrement.
Super fun and easy right? Except....that little leaf spring contact ends up rubbing against the gray code wheel and even good quality springs have a contact life of maybe 500,000 contacts. that's only 10,000 full turns - each turn is 2 x 24 contacts. if you're turning the knob 10 times a day the encoder will fail after 1000 days, about three years. And rotary encoders do fail, a lot! Heck, even our favorite scope we got right out of school has a broken encoder on the channel 1 zoom select (not surprising, since channel one is the most used and its turned constantly to zoom into the signal). A bad encoder may not be user-serviceable at all, and requires some care to desolder and replace - unless it's on a detachable cable or module, it can be a very serious repair. Flaky encoders are also a little dangerous - they can increment instead of decrement, which can be confusing and cause incorrect settings.
If you're designing a medical device or a car where there's a knob that will be used daily, having it fail after 3 to 5 years is not going to be an option - especially since the failure can happen instantly. Not a good look when a $2000 product is taken down by a $2 encoder failure. Enter the optical encoder! Optical encoders solve the contact rating issue by replacing the leaf spring with two LEDs and an optical sensor. Instead of mechanically contacting the two grey code bits, the optical sensor provides the pulses without the risk of wear and tear. These cost a few dollars more than your everyday mechanical encoder but give you rock solid reliability.
These C&K ENC optical encoders (https://www.digikey.com/en/product-highlight/c/ck-components/enc-series-encoder-switches) look and feel just like mechanical encoders. With 24 detents, they're a drop-in replacement. You can panel mount, and there's even a quick-replace connector with JST SH 6-pin socket (https://www.digikey.com/en/products/detail/jst-sales-america-inc/A06SR06SR30K51A/6009375), for easy replacement in the field.
The C+K ENC Series Optical Rotary Encoder Switches (https://www.digikey.com/short/pw8p3tf8) are in stock right now for immediate shipment from Digi-Key! Order today and you'll be reliably twistin' and turnin' by tomorrow afternoon - don't forget to pick up some JST SH cables as well (https://www.digikey.com/en/products/detail/jst-sales-america-inc/A06SR06SR30K51A/6009375)!

This is a fingertip-sized 7-segment display, so cute! we're driving it here directly with gpio pins from a qtpy samd21 chip, which, according to the internet is Not Something One Does - you're supposed to use an lcd segment driver or at least a chip with built in peripheral. and we sorta see why - there's a little ghosting from how we're driving the segments, even though we're doing our best to depower between common-pin swaps. still, its legible and allows for quick testing. this appnote came in handy to show how the 'ac' waveform is generated: http://ww1.microchip.com/downloads/en/AppNotes/doc2569.pdf one fun thing to learn is it isn't 7-segments-plus-3-commons, but rather 6-segement-select-plus-4-common with a bit of multiplexing thrown in!

we're absolutely 😍 over maceffects' clear cases. since we've got our shugart 34 pin floppy hacking well figured out (time for hardware spins!) we can now turn our attention to the Apple Disk ][ which is sort of a 'gutted' shugart drive. what better way to psych ourselves up for this work than to re-skin this disk drive? only thing we recommend being careful of: pulling the plastic wrap off can generate some pretty serious static. we used our scope (earthed) ground to dissapate as much as we could, and were wary to make sure the plastic, and us, didn't touch any components. whew! we'll start poking at this shortly.

we see our QT Py ESP32 pcbs have shipped, so it's time to wrap up this design with a tester. like the esp32-s2 qt py, we're using a raspberry pi to test because its a convenient way to run esptool for uploading data and wpa cli scan, to verify the signal strength: we program the test board with access point code, then check the rssi on the pi side. if we get a good signal we can be confident the antenna and passives got selected right. this test seems to be running well, and we'll be manufacturing SOON!

This creates the illusion of motion by rotating a series of acrylic panels that feature engravings of a single frame of animation.
A NeoPxiel illuminates the artwork engraving on the acrylic panels and changes color each frame to make a stunning effect.
Powered by the Adafruit CRICKIT and Feather M4 running CircuitPython, this uses a DC motor and a photo interrupter to trigger a NeoPixel whenever the sensor detects a break.

The Apple Disk ][ drive is a converted Shugart drive that has three power supplies: 5V, +12V and -12V. The 5V and 12V are for the motor control. Negative 12V is a bit of a pain to generate, but thankfully the -12V seems to only be used for biasing a trim potentiometer. So, we don't need a lot of current. Still, we do need to generate -12V, let's take inspiration from the classic MAX232 RS232 driver chip to find a charge pump converter!

We churned through a big pile of testers and new designs this week: two IPS TFT displays with EYESPI connectors, the VL53L4CD time-of-flight sensor, the ESP32 QT Py, an OV2640/OV5640 camera breakout, and the ESP32-C3 QT Py. With a lot of our floppy work done and tested for both SAMD51 and RP2040, it's time to move from shugart 34 pin to Apple Disk ][ which uses a different 20 pin interface. The power supply and controlling technique is going to be different for this drive because to save costs they removed and simplified the drive control system.

Over the past weeks, Ladyada and jepler have been learning about floppy flux writing. Here, jepler loads a classic game onto a Commodore SX-64 written using a blank floppy disk and a genuine GreaseWeazel interface board.

One nice thing about standardizing on Stemma QT is that it makes it super easy to swap chips out when new versions appear. Here we are reworking a VL53 breakout to remove the older chip and replace it with a VL53L4CD https://www.st.com/en/imaging-and-photonics-solutions/vl53l4cd.html which is a new time of flight sensor from ST. this one has lower range, only up to 1.3 meters instead of 4 meters BUT it can do much closer reads, as little as 1mm away, so it could be useful in some situations where the sensor could bump up against what it is trying to sense.
Aaand, everyone always asks, so! Here is the Mini Hot Plate Preheater with USB C Power Supply :) https://www.adafruit.com/minihotplate

This week's EYE ON NPI is another banger from Sensirion - who has been really rockin' out with great sensors over the last few years - it's the SEN54 Environmental Sensor Node (https://www.digikey.com/en/product-highlight/s/sensirion/sek-sen5x-evaluation-kit), an all-in-one sensor node that combines all of the Sensirion top hits in one. This sensor looks like your everyday dust sensor - just like the SPS30 particulate sensor (https://www.digikey.com/en/products/detail/sensirion-ag/SPS30/9598990), but combines additional sensors inside!
There's a few models planned for the SEN5X series - today we're highlighting the SEN54 which has * Particulate Matter - PM2.5 * Humidity and Temperature via SHT40 (https://www.digikey.com/en/products/detail/sensirion-ag/SHT40-AD1B-R3/14322709) * Volatile Organic Compound via SGP41 (https://www.digikey.com/en/products/detail/sensirion-ag/SGP41-D-R4/15652788)
(There's also a SEN55 which will include an addition NOx sensor, but it has not been released yet)
The sensor uses a sub-processor that will act as a single I2C peripheral to receive commands and send sensor data back. It's a great deal if you want a simple-to-install air quality sensor with all the goodies. There's a 3D model available for mechanical installation, and for connectivity you just need a single JST GHR 6 pin (https://www.digikey.com/en/products/detail/jst-sales-america-inc/GHR-06V-S/807818) cable which has power, and I2C or UART data. Note that the cable is not sold separately so you'll need to acquire the cable from a separate vendor or pick up the full evaluation kit that comes with a couple cables at additional cost. (https://www.digikey.com/en/products/detail/sensirion-ag/SEK-SEN5X/15903862)
The real success story here is the libraries that are pre-written and supported by Sensirion that makes getting started very very fast. We were able to wire up the SEN54 to an ESP32 board and run the BLE demo (https://github.com/Sensirion/arduino-ble-gadget) within a few minutes!
Using the Sensirion MyAmbience app, (https://apps.apple.com/us/app/sensirion-myambience/id1529131572) we could see instant data show up on our iOS or Android device. Over-all a slick and easy experience. We must say that we're really impressed with how maker-engineer friendly the sensors and firmware development is.
This all-in-one sensor board is going to be a popular environmental sensor from folks who really know environmental sensing! Digi-Key has a whole bunch of the Sensirion SEN54 sensors in stock right now for immediate shipment (https://www.digikey.com/short/pn08ff2w) and with same-day shipping, you can order today and be sensing by tomorrow afternoon!

OK we were still having some issues with mac 400k/800k floppies and their weirdly long GCR pulses so we decided to refactor our bitbanging code to use a timer capture peripheral and a pwm waveform generator (bit odd because the period is what changes there, but it is possible with most timer peripherals) We also characterized a pile of floppy drives we had - still best results came from the Sony MPF but a few other drives were able to read with 10+ (!) retries. The timer refactor didn't seem to make much difference on the GCR decoding but it seemed like the right thing to do and there's less fudge-factor dependancies on the cpu clock frequency. Also, FLOPPY SOCKS!

In order for our floppy accessing project to connect to laptop-style drives, we will need to source FPC (flex printed circuit board PCB) cables that fit the existing drives and can snake on over to our PCB. Unlike most display FPC's, these need to be 1mm pitch, and we need to watch out for whether they are A-A or A-B style. Thankfully Digi-Key stocks every length, style and pitch of FPCs you could possibly want. So let's find it and we'll order it for our prototype testing this week!

the industrious adafruit.io team did a massive refactor of the way we support i2c sensors in wippersnapper to allow automatic generation of new sensor devices without having to hardcode how they look and are treated in the backend (and dontcha know, we even made the repo where we are keeping all that metadata public over at https://github.com/adafruit/Wippersnapper_Components/tree/main/components/i2c) and to celebrate, we added TWO more sensors - not only the AHT20 but also the DPS310 and ultra-popular BME280. here we show just how fast it is to set up data logging to adafruit.io with NO code, NO soldering, NO command line and NO toolchain. plug in the bme280 sensor in the qt py s2, open up wippersnapper, check the i2c address appeared, then connect to the new device and select which sub-sensors you want to log into a feed. boom, all in one tiktok minute! more plug-n-play i2c sensors coming soon...

ok getting back to our floppy project (after we did a bunch of hardware designs last week, stay tuned for some exciting new products!) here's a USB floppy drive that we will use our 'flooper board to turn from a 26-pin FPC into a 34-pin IDC. and...it works! it's a straight conversion, just needs the mechanical adaptation here, and you can use these common USB floppy drives as an everyday standard magnetic-flux device. here we're reading an IBM MFM floppy. the samsung 321 can read mac 800ks, but the teac fb-05 is not as happy with those pulses!

ok cats and kittens, we know you missed the floppy hackin' so you should be glad to know we're BACK on the floppy kick, with some timer driven code for capturing and generating flux pulses. we're not 100% sure we need timers to do it but we were having a few issues with writing floppies consistently so figured this could help. today we wrote an ibm mfm floppy and then read it on another floppy drive connected to our computer. being able to write floppy disks also means we may be able to categorize disk drives better since we can test writing and reading pulses. we also put together one of our 'Floopers in order to properly test a laptop drive - successfully! finally, we saw this nifty cut-tape-removal tool on twitter https://twitter.com/dannymodules/status/1490248252465184771 and we're going to try jlcpcb's 3d printing service to get a couple made since they seem super handy
The Great Search - 26 pin 1mm FPC cable for laptop floppy drive https://www.digikey.com/short/vbzqw277
In order for our floppy accessing project to connect to laptop-style drives, we will need to source FPC (flex pcb) cables that fit the existing drives and can snake on over to our PCB. Unlike most display FPC's, these need to be 1mm pitch, and we need to watch out for whether they are A-A or A-B style. Thankfully Digi-Key stocks every length, style and pitch of FPCs you could possibly want. So let's find it and we'll order it for our prototype testing this week!

the silicon shortage has pushed a lot of revisions onto our plates, chips and displays both have gotten a lot of updates. here we are testing a revision of product https://www.adafruit.com/product/911 which is a 2.0" TFT with NTSC input. what better source of stable NTSC signal than a raspberry pi zero? simply solder wires to the TV pins and keep HDMI disconnected for a quick way to verify the screen works as intended.

Luxuriously Long Stemma QT cable samples!
I2C was never meant to go 200, 300 or 400mm but we laugh in the face of death thanks to these samples we got of some looooooooong stemma qt cables. each cable has two JST SH connectors on either end and a PVC sheathed center. we were inspired by this tweet https://twitter.com/lovyan03/status/1480867328783163396 about I2C wire interleaving with power in order to avoid cross-talk for long cables (I2C is not differential so you definitely do not want to use twisted wires!) if you look closely, the cable is flat and has the red power wire between SDA and SCL instead of having them next to each other. we're just trying it out here with our fancy new ESP32 Feather V2 which has an onboard STEMMA QT connector.

This week's EYE ON NPI will be your loyal friend like a pet dog - it's Authentrend FIDO2 Biometric Security Keys (https://www.digikey.com/en/product-highlight/a/authentrend/fido-biometric-security-keys). These FIDO2 compatible USB dongles have an absolutely adorable built-in fingerprint sensor on the end, which means they have an additional layer of security in addition to ownership: you also need to have the matching fingerprints.
This is great when you want to secure something with 2 or 3 factors (https://en.wikipedia.org/wiki/Multi-factor_authentication) and possibly without having to have folks remember or change passwords. Historically, authentication was done with just a username and password . But, as we've all learned, usernames and passwords can be guessed or stolen or hacked! Some folks have two-factor time-based code cards (https://www.eff.org/deeplinks/2016/12/how-enable-two-factor-authentication-paypal), apps (https://support.google.com/accounts/answer/1066447?hl=en&co=GENIE.Platform%3DAndroid) or SMS messages which add "something you own" to the list.
FIDO/U2F cards have been around as a USB-based authentication system for a bit, and they're slowly gaining traction through an open standard which makes it easy to integrate with web or desktop applications. (https://fidoalliance.org/fido2/) We're huge fans of moving all of your security risk to hardware like these, that abide by open standards - it's very hard to create a secure hardware device. Firmware, storage, even when encrypted, is not often crackable or glitchable (https://blog.securityinnovation.com/glitching-firmware-over-usb-using-facewhisperer). Using an external dongle gives you a hermetically sealed challenge-response system from a company that does only one thing. because the private keys are stored in the hardware, you don't have to store them on device in firmware.
These come in a few different mechanical shapes and flavors, including USB A fingerprint key (https://www.digikey.com/en/products/detail/authentrend-technology-inc./ATKEY.PRO-TYPE-A/15761935), USB C fingerprint key (https://www.digikey.com/en/products/detail/authentrend-technology-inc./ATKEY.PRO-TYPE-C/15761936), and a keycard that has NFC, BLE and a USB-A flip-out (https://www.digikey.com/en/products/detail/authentrend-technology-inc./ATKEY.CARD/15761933) We were able to get our fingerprint entered into the dongle using Windows 10's key manager, then used the same dongle to add 3-factor authentication to our Google account.
Of course you probably want to use it for non-website projects too! You can interface with the security dongle very easily using the python-fido2 library (https://github.com/Yubico/python-fido2), which means any embedded Linux/single board computer will be able to have trusted authentication added with USB. This could be a very inexpensive and fast way to add trusted authentication for your product without having to hire a cryptographer.
There are plenty of Authentrend ATKEY.PRO TYPE-A (https://www.digikey.com/short/p3t50d14) in stock at Digi-Key right now, that's the one we've been using the most, but do check out the other variants as well, such as the USB C, if your computer has type C ports (https://www.digikey.com/short/p3t50d14). Order one for each user today, knowing that the FIDO2 standard will mean easy and trustworthy deployment for many years!

Adafruit's Limor "Ladyada" Fried and Phillip Torrone will host the Hack Chat on Wednesday, February 2 at noon Pacific / 3pm Eastern.
https://hackaday.io/event/183426-floppy-interfacing-hack-chat-with-adafruit
When a tiny fleck of plastic-covered silicon can provide enough capacity to store a fair percentage of humanity's collected knowledge, it may seem like a waste of time to be fooling around with archaic storage technology like floppy disks. With several orders of magnitude less storage capacity than something like even the cheapest SD card or thumb drive, and access speeds that clock in somewhere between cold molasses and horse and buggy, floppy drives really don't seem like they have any place on the modern hacker's bench.
Or do they? Learning the ins and out of interfacing floppy drives with modern microcontrollers is at least an exercise in hardware hacking that can pay dividends in other projects. A floppy drive is, after all, a pretty complex little device, filled with electromechanical goodies that need to be controlled in a microcontroller environment. And teasing data from a stream of magnetic flux changes ends up needing some neat hacks that might just serve you well down the line.
So don't dismiss the humble floppy drive as a source for hacking possibilities. The folks at Adafruit sure haven't, as they've been working diligently to get native floppy disk support built right into CircuitPython. To walk us through how they got where they are now, Ladyada and PT will drop by the Hack Chat. Be sure to come with your burning questions on flux transitions, MFM decoding, interface timing issues, and other arcana of spinning rust drives.

This weekend we got to play with a VFD tube. This ancient technology uses a gas tube to light up segments. In order to activate the fluorescence, we need to provide 20 to 30V DC on the segments. Not a lot of current, maybe 1mA each, but definitely needs to be a high voltage. For lower voltages, we could use a switched-cap converter. But for this, we'll need a proper booster! Let's find a small, low cost, simple, and available boost converter that can give us these bias voltages from 3 or 5V DC input.

Music by Bartlebeats https://soundcloud.com/adafruit
This weekend we got a LOT done with new and revised stemma boards! For revisions, we got, assembled, and tested the DRV2605 and ADS1x15 QT boards - both work great. we also put together and tested our qt py lipo BFF and it works great, for our final version we added a battery monitor resistor divider. in order to test the BFF we needed a power monitor like the INA219 and realized at like 1am that we didnt have an INA219 on us, so we ended up bringing up the INA228 prototype we had and wrote a quick driver for it. Unfortunately the INA228 is totally unavailable so it won't be in the shop soon. finally, we got a shipment of some samd21e18's in - from an order over 6 months ago! so we can do some more trinkeys - one trinkey that we wanted to put together for a while was an 'ice tube trinkey' - with a single digit VFD display. First up? figure out pinouts and voltages for this cute IV-3 tube! - then we can wrap it up in a circuit board design.
The Great Search - 20 to 30V low current booster for VFD or OLED https://www.digikey.com/short/q4hvnttb
This weekend we got to play with a VFD tube. This ancient technology uses a gas tube to light up segments. In order to activate the fluorescence, we need to provide 20 to 30V DC on the segments. Not a lot of current, maybe 1mA each, but definitely needs to be a high voltage. For lower voltages we could use a switched-cap converter. But for this we'll need a proper booster! Let's find a small, low cost, simple, and available boost converter that can give us these bias voltages from 3 or 5V DC input.

answering a few questions about our tiny lil DOOM & emulator-playing device we designed and prototyped this weekend...one question is does it play sega and the answer is YES! there's an SMS emulator and we loaded up sonic just fine. second question is how to enter in 'keypress' cheats - answer is that they are accessed and enabled through the options menu. so if you want a BFG on level 1, you can haz it!

part of our floppy quest is we want to read mac 800k floppies - partially because there's a lotta good content out there on 800k floppies, and partially because we are still heading towards imaging the prince floppy (which, being 800k formatted made it a bit of a pain to read).
1.4MB floppies on mac are easily readable because by the time they got to 1.4MB apple stopped being clever with their disk formatting. but 800K floppies are really clever/freaky!
unlike ibm pc formatting, there are not a fixed number of sectors per track. there's four groupings of tracks, and there are MORE sectors on the outer tracks (tracks 0 thru 31) than on the innermost sectors (64 thru 79). thats because there's technically more surface area on the outer edges of the disc where the lower number tracks live.
mac floppies also rotate at different speeds depending on the track, which is also a joy. given its quite hard to find and control those old floppy drives compared to our bog-standard 'shugart 34 pin' pc types, there's incentive to try to get these to read cleanly on cheap and available hardware. (apple superdrives are...not cheap. no not that superdrive, the OTHER one)
but the problem remains: the inner tracks have flux pulses that are significantly longer than the outermost tracks, because if we have a flux-per-inch limit, then we have to spend more time to traverse that distance on the inner tracks.
and ibm pc mfm-optimized drives do not like this: they really expect the flux to change on very specific timebases: about 2us, 3us and 4us -ish. and once you start reading those longer pulses they get into 10 or 11us and that is much longer than the drive and media expect.
firstly, the HD diskette isn't really meant to encode such long pulses, and secondly the disk drive automatic gain control starts getting amped up after 5 or 6us and thinks it must have lost a pulse, so it ends up reading old/weak flux inversions and 'splits' the longer pulse into 2 or 3 ghost fragments. the flux decoder is getting extra bits where it ought not, and gives up.
we're going to order some true DD diskettes to see if that helps with the first issue. for the second issue, we tried setting the DENSITY input low but that didnt help - we're thinking we could try to detect spurious pulses to try and repair the GCR cells during flux read. hopefully we'll figure something out?

This week's EYE ON NPI is gonna be a hit for anyone who has ever had to add terminal blocks to a design, then dealt with the frustrations and costs of having a mixed SMT/THM process. Presenting... TE Connectivity Board-Mount Surface Mount Reflow Terminal Blocks (https://www.digikey.com/en/product-highlight/t/te-connectivity-amp/board-mount-reflow-terminal-blocks). Yes! Almost everyone has created a design that had a raw-wire to board connection. And a super popular way to make a flexible but durable connection with a range of wire thicknesses is to use the tried-and-true Terminal Block (https://www.digikey.com/en/products/filter/terminal-blocks-wire-to-board/371).
Digi-Key carries thousands of different terminal blocks in all sizes, pitches and configuration. Multiple rows! Plug type! But they all tend to be through-hole type. Not surprising, because there's a lot of mechanical torque on the connector when twisting, and also a lot of current passes through these connectors - they're often used for power supplies, and motors, that can draw amps. Given that they are through hole, a selective, manual or wave-soldering step is required for manufacture. (https://blog.adafruit.com/2014/03/26/ace-production-selective-solder-kiss-102il-apex-expo-adafruitapex-ipcshow-ipcshow-apexexpo/) And believe us, while these machines are totally awesome - they also require a lot of maintenance and time to run. (https://blog.adafruit.com/2018/07/02/programming-the-crickit-for-selective-soldering-a-deep-dive-part-3-adafruit-crickit-manufacturing-selectivesoldering/) So we try very hard to go with SMT-only processes: it's a lot faster and cheaper to only use one machine than to use two machines where boards have to move through two machines.
We've used some "SMT Terminal blocks" before in products like on our buckaroo bonsai (https://www.adafruit.com/product/4534), which only needs 2 wires connected, and low power ones at that. Since hauling all the PCBs to the selective for just two pins is a total pain, we figured its better to go with this 'side insert' type. It works fairly well but doesn't have the adjustability we love with the cage-type terminal blocks.
Which is why we are diggin' this series from TE, available in various pitches (3.5mm, 3.81mm or 5mm) and pin counts, from 2 to 7 pins. They look just like your everyday terminal blocks, but with flat rectangular pads that are bend 90 degrees to the back of the package, and mechanical shear/locating dots that will keep the connector from lifting up. They're even packaged in a chunky tape and reel, ready for use in your machine line. Note that even with the locator posts and large pads, you'll still want to make sure that you don't have a lot of force coming in from the front: The posts will protect against torque from the top but probably can't help much if they are lifted up from the front.
If you only need a couple terminal blocks in your design and want to save process costs - or if there's a reason you can't go with a through-hole block - these TE Board-Mount Reflow Terminal Blocks (https://www.digikey.com/en/product-highlight/t/te-connectivity-amp/board-mount-reflow-terminal-blocks) will do great. And, they're available and in stock at Digi-Key right now! Order today for immediate delivery, so you can be twistin' and terminatin' by tomorrow afternoon.

This week's EYE ON NPI is going to stick with you for a looooong time - it's 3M's VHB Tape (https://www.digikey.com/en/product-highlight/3/3m/vhb-tape-5906) also known as "the tape you use when you want it to stick together forever". This tape is the stuff of legend - it's incredibly thin but strong, easy to apply and gives you near-epoxy-level strength in seconds.
3M VHB tape consists of a durable acrylic adhesive with viscoelastic acrylic foam. This provides an extraordinarily strong double-sided foam tape that adheres to a broad range of substrates, including aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete. Our bonding tapes provide excellent shear strength, conformability, surface adhesion, and temperature resistance. They are commonly used in applications across a variety of markets, including transportation, appliance, electronics, construction, sign and display, and general industrial. Reliably bonds a variety of materials with strength and speed for permanent applications.
Seriously - we've seen it easily attach to metals, wood, plastic, rubber and it wont dry out and peel off like most foam tapes. It's super strong, to the point we often feel kinda weird when we use it because don't expect such incredible tensile strength. You can even build a push-scooter that is kept together just by VHB Tape as seen at https://www.youtube.com/watch?v=rxJ-kU6Z8GY.
It's double sided tape. but its sticky enough you cant just have it on a reel like office double-sided tape. Each reel comes with a smooth plastic layer in between - we suppose this is the one material it doesn't stick to very well. Clean both halves with 50/50 IPA. Carefully apply it while still on the plastic reel and then remove the protector. Now press the other half you want stuck together. Wait up to 3 days for max hold strength, but it's pretty darn strong instantaneously.
This VHB is VHC (Very Heckin' Cool) and extremely useful when you just want to attach this-to-that, no matter what material or environment. You can get this in sheets (!!) and rolls at Digi-Key. We are partial to the 5 yard 1/2" wide roll which has just enough to be useful (https://www.digikey.com/en/products/detail/3m-tc/1-2-5-5906/5039231) but there's also a 1" wide version (https://www.digikey.com/en/products/detail/3m-tc/1-5-5906/5039233) and we picked up one of each.
Whatever 3M VHB tape (https://www.digikey.com/short/bvq23nw9) style you're looking for, Digi-Key has them in stock for immediate shipment. Order today and you can be stickin' this-to-that by tomorrow afternoon!
For our little QT Py gamer, we want to have an onboard headphone jack that folks can plug into to get audio out. Last week, we picked out a headphone amplifier chip. This week, we'll be sourcing a headphone jack we can use that will be slim enough to fit between the headers.

from ladyada "we had a lot of success with our retro-go port (even submitted a PR) and now we've got the NES emulator 'nofrendo' working. we're reaaaaally familiar with this emulator, having ported it to the SAMD51 a few years ago (see https://learn.adafruit.com/nes-emulator-for-arcada for deets). its a fairly portable emulator that can run many games. we popped in a micro SD card with a bunch of roms and had a go at playing some of our fav NES games: kid icarus, arkanoid, tetris and of course dragon warrior - which was the first rpg game i played on a console and was totally amazing (and paved the way for jrpgs like final fantasy, xenogears, legend of gaia, etc) i still think about farming those steel slimes... anyways! since the ips 1.3" tft is 240x240 pixels it does a pretty good job of being smol but fitting the 256x240 native resolution. you can either scale the output, or drop some pixels on the left and right. with audio and playback working this may the the smallest pixel-perfect nes gaming emulator ever made :) "

after nofrendo/NES emulation, the next one we tried is 'gnuboy' which is a gameboy (color) emulator. we remember getting a gameboy when they came out, it was absolutely amazing to play tetris anytime we wanted. really chewed through nicad batteries tho - we had to have one set charge while we played. anyways, gnuboy works a treat and maybe we'll finish super mario world again (there was a submarine, right?)

After all the functionality has been worked out with a new boards, its time to do last power draw checks to make sure that low power functionality is verified. historically, we haven't cared too much about low power uses - stuff would be plugged into a 9V adapter anyways. but in the last couple of years we've tried to make whatever small changes we could to make our boards work well in deep sleep. this qt py esp32 pico can get down to 70uA which is pretty good! that means the cp2104 and neopixel are not drawing current. given we don't have a 32khz crystal on board, we think this is as long as it gets!

This week we put together our first QT Py accessory board which turns the diminutive board into a tiny gaming platform with 10 buttons, a TFT screen, micro SD card, and headphone out. The PCBs showed up late last week so we quickly soldered one together and we pretty much got it going! then we ported arcada to it (that's our Arduino button/display library) so that we could do basic tests on the hardware. finally we spent friday and saturday on getting retro-go to work so we could use it as an emulator for nes/gameboy/sms/doom/etc. most of that was picking the right idf, learning how to work with CMake and doing the hardware port to support the i2c gpio expander.

we're taking a short break from floppy disk hacking (don't worry, we're nowhere near done and this will all tie together - promise!) and working on a QT Py gamer backpack we designed. the qt py esp32 pico here plugs into the back to drive the 240x240 IPS display with an SD card slot, battery charging, and an AW9523 GPIO expender for all the buttons. we wanted to make a very smol odroid go-like since that hardware had a ton of support. we've found a great open emulation project with a LOT of emulators supported and a very easy-to-understand structure at https://github.com/ducalex/retro-go so we're having a 'go' at porting it over! we had to use esp-idf 4.2 and this is the first time we've used raw idf and...we really like it! ninja is such an incredibly fast compiler and we like the 'flash n monitor' helper. so far we've got the chip booting and the tft is kinda coming up, just need to tweak the init for the st7789 instead of ili9341.

jepler picked up some retro Apple floppy disks online. With Adafruit_Floppy and the Adafruit fork of fluxengine, they read out the data and loaded it in a Mac emulator. What a blast from the past, dithered "screen posters" using After Dark technology & comic book artwork.
Not all drives can read Mac floppies, a Sony drive worked but a Panasonic didn't.

About a week ago we re-spun our ESP32-S2 QT Py into an ESP32-S3 version (the chips are very very similar but NOT drop in compatible!). we just got the PCBs in last night and threw one of these together. compared to the S2, the S3 adds a second core back, and adds BLE as well. while there is no arduino support yet, we do have preliminary CircuitPython support! good enough to test each pin, the analog inputs, i2c control of a display and even connect to wifi to grab some data. there's still more to go but we've got the hardware in a state that's good enough to try and order our first set of PCBs for assembly.

For our tiny handheld gamer board, we want to have a headphone driver that does not require a lot of board space. Even if the chip is small, most simple amplifiers require output blocking caps to avoid DC bias on the speakers. But, now-a-days, you can get 'cap-less' drivers that generate a faux-ground. This makes for a very tiny board. Let's find a chip that is small, but not BGA/CSP, that will fit nicely into our design

This prop is inspired by Tusken Raiders chief staff. Each part is printed in a different colored filament, so they're ready to go right off the printer.
Each piece features threaded connectors so it's really easy to assemble and take it apart. They can be printed without any supports and don't need any screws or glue.

This weekend we dove headfirst into getting fluxengine and our 5.25" disk drive working with the floppy featherwing. good news is that we were able to add support to Adafruit_Floppy and with a little refactoring, add 360K disk MFM decoding. we thought we didn't have any DOS floppies but we did find one in a pile (mouse driver). we then used fluxengine to read the data off to verify before implementing mass storage support. once we got that working we spent a few hours on C64 disk reading, these disks are kinda odd and not formatted like 'normal' diskettes - there is a different encoding scheme and variable sectors per track! we also designed a feather esp32 v2 and a smol handheld game BFF for QT Py.

OK after much fluxengine hacking (wherein we wrote a bunch of code, then ended up deleting all but like 4 lines) we have it successfully interfacing with the adafruit_floppy 'greaseweazle compatible mode'. we can now use both tools to read and parse flux data which is great as fluxengine has a bunch of formats it supports. we did find one MFM 360K DOS disk in our collection - so we are able to verify that chunky floppies work just as well as 3.5"s. this is one good example of why we cant 'just use a USB floppy drive' - there is no 5.25" usb floppy drives (yet). after imaging this disk we found some classic mouse driver content - including an exciting new concept in Mouse control!

5.25 inch 360K DOS Floppy drive as a USB key
with fluxengine support out of the way, we're on to refactoring our adafruit_floppy library code to support this old-fangled 360K double-density disk http://fileformats.archiveteam.org/wiki/PC-DOS_360K_format this format was pretty common back in ze day. it's not too different from our more common 3.5" 1.44MB in that it has MFM encoding, two sides and FAT12 formatted. but it does have a quarter of the capacity as it has half the tracks (40 not 80) and half the sectors (9 not 18). so, a little refactoring this afternoon and now our USB mass storage example is happy to make this drive appear as a 360KB USB drive. we can access the files just fine - this may be the first time someone's developed a USB MSD controller for these older disks, it's like a really really heavy usb key :)

we're poking at our 5.25" disk drive and we'd like to get it working with our Adafruit_Floppy code so we can read older diskettes. we can't find our DOS formatted floppies at the moment, we could probably just pop those in and run the USB-floppy interface code to have it show up as a drive. buuuut, we happen to only find our apple ][ and c64 diskettes so far. whoops! well, this is good incentive to get fluxengine support working - it's an alternative to greaseweazle and seems to support more formats including c64 disks that are gcr instead of mfm encoded. fluxengine has greaseweazle support so it should 'just work' right? well turns out we had a few sticking points to getting data read working via the low level win32 com port interface with the CDC class driver (did you know you MUST set dtr? this cool tip could save you 4 hours). now that we're over that hurdle we can sew up the rest of the interfacing tweaks to get fluxengine working!

having converted MFM pulses to sectors, you may be surprised to know its only a couple lines of code to have a microcontroller access the disk and underlying file structure. we use SdFat library, an SD card interface library that is really good, and subclass it to provide new functions for reading (and later, writing) sectors. then you can just treat the drive like a very small SD card. why does this work? turns out SD cards are pretty much the same as extremely large floppy drives: blocks of data are 512 bytes each, and both are formatted with the same kind of filesystem structure called FAT that was invented in 1977 for floppies but persists to this day. SdFat supports a particularly early and compact version called FAT12 and even does long filenames. now our arduino programs can access files on floppy drives with ease!

we got some samples of the esp32 pico v3 02 modules in from Espressif and they're smaller than we expected! we thought they were the same size as the esp32-s2 mini modules we've been using but they're actually a bit smaller in each direction. that actually works out to our advantage because it means it can fit on an itsybitsy sized board (the mini modules cannot, too wide!) so this could be a good candidate for an esp32 itsy' that comes with 4MB of flash and 2MB of PSRAM. probably needs to have double sided but i think we can work it out.

This week's EYE ON NPI is FIRST in it's class - it's the Molex FIRST Robotics Components Cable Kit (https://www.digikey.com/short/nddt5cvr), designed specifically for the thousands of high school students who are participating in FIRST robotics classes and competitions (https://www.firstinspires.org/). This box comes chock-full of 2 and 3-conductor color coded cables, with different pitches and contacts.
If there's one thing we remember from our explorations in robotics (or, heck, even watching robotics shows on TV) it's that mechanical connections are a huge concern. You can have the fastest bot, with the most flawless code, and all will be for naught if your power cable comes loose, or a sensor line is shorted to ground. A lot of folks learn about cable crimping to make custom cables - hey we even have a tutorial video on it (https://blog.adafruit.com/2021/04/02/new-video-crimping-connectors-collins-lab-notes-adafruit-collinslabnotes/). But here's the thing - even if you have a great crimping tool, it's extremely hard to do as good a job as a auto-crimping machine. You have to strip the wire perfectly, insert it into the tool, and press down with just the right amount of force. It's hard to get the crimp to be strong enough to grip the wire strands and cable cover but not so tight that it cuts into the housing.
As we've gotten older, we've stopped trying to crimp cables, and instead we go with pre-crimped cables or housing + 'raw wire' sets like these (https://www.adafruit.com/product/3142). And that's what Molex has done here. They've chatted with FIRST robotics teams, including ones they sponsor, to figure out what cables are they using. Turns out they like the Molex SL Modular system (https://www.digikey.com/en/product-highlight/m/molex/sl-modular-connectors). Then, they put together a low cost kit with a whole mess of cables and housings that will let you outfit a robot with power, servo, and sensor wires easily. You can check out the unboxing on YouTube, with Jonathan and Alan, where they go through each cable and what it's good for. (https://www.youtube.com/watch?v=gwokT0HmnB8)
This cable set is good for any FIRST robotics team and it's plenty good for any home or company robotics or mechatronics project. It's also a great deal where you get a bunch of cables made by Molex themselves, at better prices than sketchy knockoffs!
Digi-Key has tons of the Molex FIRST Robotics Components Cable Kits in stock right now for immediate shipment (https://www.digikey.com/short/nddt5cvr) - order today and you can be wiring up your robot by tomorrow afternoon.

woohoo, we got on-the-fly mfm decoding working so we have fluxes converted to bytes, and all the sectors are verifying right. wouldn't it be neat if we could use tinyusb's mass-storage class to make a usb floppy drive?
tinyusb is an adafruit-sponsored open source usb stack that lets a microcontroller act like just about any usb device: like a keyboard or mouse or midi or disk drive. the latter is what we're most interested in - and all we have to do is tell USB MSD how many sectors we've got (18 per track, 80 tracks, 2 sides) and supply the 512 byte sectors when we get a SCSI READ10 callback.
bam, it 'just works' as windows still recognizes and supports FAT12 devices! we can open up and skim through the text files we've copied over earlier, and look who phrack 49 had an interview with!

OK more floppy fun, this time with jepler helping out - we're doing some cross-platform code sharing where the mfm decoding C code is going to be the same for arduino and circuitpython. jepler wrote up the mfm-decoding-and-crc-verifying for circuitpython and it was pretty easy to integrate it into arduino so that we can not just read flux data but the actual binary data! here we've got a simple floppy track dumper that goes from track 0 to 80, alternating sides, and prints the hex and ascii output. and, now you can see why we went with text files as a test bed - its very easy to see that our cross-sector reading is correct because the text continues smoothly from one to the other. this means we're getting close to being able to access the file system in arduino which means we are ONE STEP CLOSER to building a project ladyada has wanted since she was a teenager (can you guess what it is?) anyways, code is here for the curious https://github.com/adafruit/Adafruit_Floppy/blob/main/examples/mfm_test/mfm_test.ino

jepler just tossed us a build of circuitpython with the new native 'adafruit_floppy' module which implements MFM decoding 'on the fly' to provide python-native filesystem support for floppy drives! yep, you can now store files and code that is read or executed off of a floppy disk. we whipped up a quick demo that lists the files on a disk and pages through any textfiles it finds, and tossed on a copy of phrack 49 http://phrack.org/issues/49/1.html - its a total classic - we were able to page through the whole thing to verify the FAT12 filesystem works as expected! next up, file writes?

For the ESP32 Pico QT Py, we will be including a CP2102N (covered a few weeks ago!) to do USB to serial conversion. We also need a dual NPN transistor to do the funky reset/boot toggle required to reset the ESP32 into bootloading mode. On our Feathers, we used two SOT-23's but we have so little space, we'd like to find something the same size as our BSS138 duals we use on STEMMA QT sensor boards!

Music by Bartlebeats https://soundcloud.com/adafruit
This weekend we cranked through 3.5 QT Py designs (we didnt finish routing one, its a toughie!) - we already make SAMD21, RP2040 and ESP32-S2 and we wanted to add some more chips to the mix: ESP32-S3 (dual core version of the S2), ESP32 Pico (OG ESP with built in flash/psram), ESP32-C3 (Risc-V wifi!) and nRF52840 (BLE wonder-chip from Nordic). the last one is what we didn't get to finish routing because its a particularly tough one. The other 3 worked out fine with a 4 layer PCB. We also designed a few 'BFF' boards - that fit onto a QT Py like a shield. Finally, we did get our floppy featherwing and adapter/breakout in, which lets us clean up our floppy wiring - we'll be able to do more floppy stuff with less mess!

hey everyone! after taking care of some fruit-biz-stuff and releasing some exciting new products, we're back to fun...FLOPPY FUN! we want to add floppy writing support but our wiring harness was a little unwieldly - thankfully our floppy featherwing we designed last week arrived and after some quick soldering and pin define changes, it works just as well. now we can continue on our floppy journey - expect MORE 💾💾💾 soon as we continue development. Watch and star this github repo to get updates as they happen https://github.com/adafruit/Adafruit_Floppy :)

Adafruit Floppy is a project to make a flexible, full-stack, open source hardware/software device for reading, archiving, accessing and duplicating floppy disk media. It joins a family of open source hardware and software such as greaseweazle and fluxengine, and will attempt to increase the availability and accessibility of floppy disk controllers by: porting the greaseweazle / fluxengine firmware to Arduino so that it is less tied to specific hardware, adding firmware support for the RP2040 chip / low cost pico, adding hardware support for reading apple ii disks including index sensing, adding woz/a2r support to greaseweazle / fluxengine, and investigating analog flux data acquisition methods for repair of damaged disks. all of this with permissively licensed hardware and software so folks can re-create without licensing agreements, NDAs, or discussion.

This week's EYE ON NPI is the first of the year, and we love to celebrate a NEW year with a NEW product - this week it's Jonard Tools’ Technician's Tool Bag Backpack (https://www.digikey.com/en/product-highlight/j/jonard-tools/technicians-tool-bag-backpack), an awesome bag that is perfect for technicians or engineers who carry a lot of tools to job sites or back and forth from work. Jonard Tools (https://jonard.com/) is right outside of White Plains, NY, so we can practically call them next-door neighbors! We love to feature new companies and especially ones here in NY state.
This backpack is super beefy - it's basically a toolbox but with straps. Instead of throwing stuff into a duffle bag, or courier bag, and then digging through it desperately trying to find the wrench or pliers you need, it's got pockets for everything so you can always locate the tool without sticking your mitts into a bag of sharp and pointy things.
Some highlights from this bag:
- Durable fabric - the bag is made from really tough fabric that is puncture and weather resistant
- Rubberized bottom - it's totally waterproof, and dense which means its both protected no matter what its on top of or if it's used outside AND it sits flat without tilting over
- Clip for a measuring tape - this is so genius, there's a metal clip for any kind of tape to securely attach on the outside
- Outer front has thick elastic on front with 10 slots for quick tool storage, and a big hook-and-loop (sometimes referred to as Velcro) patch
- Detachable webbing loop for electrical tape (or other tape)
- Like half a dozen sewn-webbing carabiner-clip points
- Top front zipper pocket with hard shell and soft lining for safety glasses (or sunglasses / regular glasses!)
- Front pocket for paperwork or a small laptop (or phone)
- Big-ass main pack with dozens of pockets and loops including TWO multimeter pockets with a hook-and-loop top to secure the probes
- Strong zippers on each pocket with nice rubbery pull tabs
- Padded shoulder-blade sections on back with breathable mesh
- Padded and curved straps with a chest-clip
- Two handles on the top for each side so you can yank or carry even if open
- Lots of padding between each pocket so you don't get accidentally poked by a screwdriver!
- Free stickers, who doesn't love that?
Check out the video which goes through all of these features step by step (https://www.digikey.com/en/videos/j/jonard-tools/jonard-tools-technicians-tool-bag-backpack)
This is a really nice backpack - it's really clear that the folks at Jonard use and carry tools all the time and decided to invent the ULTIMATE technician backpack. It's full of little details that I would not have come up with, but once I realize what they are it's like "wow that is so handy!" We're going to give this to our facilities team here at Adafruit so when they travel between floors to fix stuff they can just grab the backpack and have all their tools with them for whatever problem comes up.
The Jonard Tools Technician's Tool Bag Backpack ( https://www.digikey.com/short/307z0ftp) is also an excellent deal - at under $100, it's extremely well made, and will last decades. Digi-Key has this in stock right now for immediate shipment. It would make a great gift for a technician you know, either from a friend, family member or of course, a team-mate.
Order today (https://www.digikey.com/short/307z0ftp) and Digi-Key will send this pack packin' same day for shipment to your home.

OK, so one challenge we've disk-covered (ha) doing floppy interfacing is that you need to really power them right. The power connector is a keyed 2.5mm pitch right angle PCB mount part (a Berg Connector https://en.wikipedia.org/wiki/Berg_connector). Let's find a connector on Digi-Key we can use in our design!

The week between Christmas and New Years is usually a time when we get to play with some new technology since a lot of people are out and many meetings are postponed. but this year we played with some old technology! we tried hooking up a 3.5" floppy drive to a microcontroller to see if we can read data from it. we learned a lot about floppy interfacing and also made a library that will connect with greaseweazle software to dump disk images using low cost hardware like the rp2040 pico

now that we have successful flux reads, its time to get flexible! we've swapped our SAMD51 feather board out for an RP2040 feather. not only is this feather a lovely pink shade, but it comes with a totally different chipset. oh no, do we need to start over completely with a new toolchain, timer configuration and dma library? nope! our code is hardware agnostic enough that with pin name tweaks and a couple ifdefs, we can use it just fine with greaseweazle again. so now our library has 2 chips it can use, very handy when there's a silicon shortage going round. next up, could we use the $4 raspberry pi pico board??? stay tuned :)

It joins a family of open source hardware and software such as greaseweazle and fluxengine, and will attempt to increase the availability and accessibility of floppy disk controllers by: porting the greaseweazle / fluxengine firmware to Arduino so that it is less tied to specific hardware, adding firmware support for the RP2040 chip / low cost pico, adding hardware support for reading apple ii disks including index sensing, adding woz/a2r support to greaseweazle / fluxengine, and investigating analog flux data acquisition methods for repair of damaged disks. all of this with permissively licensed hardware and software so folks can re-create without licensing agreements, NDAs, or discussion.

we fixed some track seeking code errors we had, and now we're able to start getting data from greaseweazle. since the diskette we've got is an ibm pc 1.44MB format we can use the built in ibm pc MFM format decoding module. the good news is that its able to decode some tracks...but its not able to decode all of them, like it'll read 10 good sectors in a row, then just cant find any sectors at all - which is a little suspicious. makes us wonder if we got the flux transfer and index pulse encoding right, or if its a formatting thing, because the diskette is readable on a computer with a usb drive connected.

time to wrap up today's hacking! we had a goal of finishing today with a raspberry pi pico board being able to read out flux off a floppy disk, and here we are: this is a ultra-low cost dev board, only $4 and 15K in stock at Digi-Key https://www.digikey.com/short/f2d841fn - a little soldering is required to attach header but the wiring is straight forward: start at GP2 and connect all the pins thru to GP14 in a row, skipping over the ground pads (dont forget to connect one of the grounds of course) we just tested dumping our 1.44 HD diskette just fine. in the next week we'll try to add flux writing support (we've only done reading so far), trying out HFS DD (so we can image @anildash's prince floppy), completing a PR to greaseweazle and maybe trying out the disk ii connection. a great way to kick off 2022, happy new year!

whew! so, turns out it was an underspec'ed power supply. so now we know, 500mA is not enough for a floppy drive you really need 1A. but with that out of the way, we were able to cleanly read all 160 tracks of flux from a floppy disk! this particular disk is one that our friend hid in that place that one time, and we've been waiting to be able to see what's on it... will we be able to extract the sectors and discover what secrets lie within??!?

HAPPY NEW YEAR EVERYONE! we're ticking down the new year safe and sound here at home together, with a big mug of cocoa, and a lot of floppy hackin'. tonight we started adding 'greaseweazle' support to our arduino floppy library. this will let us use any fast-enough arduino hardware with a fabulous open source flux parsing tool that is written in python. basically, we send the flux pattern for each track over usb serial for it to be parsed or saved on a computer. we have been adding each command throughout the day: enabling the motor, running a bandwidth check, setting drive parameters, etc. we are halfway through the track reading code - we got the read data arriving safely at the computer, but it seems that there is a way to 'encode' the index pulse into the flux stream and we have to figure out what polarity and data format its expecting. still, feeling really close! hopefully will be able to dump our first disk image this weekend :) code is here while its being worked on https://github.com/adafruit/Adafruit_Floppy/blob/main/examples/greaseweazle/greaseweazle.ino

we're going to back up a little in this part - we have MFM and index pulse data coming out of our chonky panasonic 3.5" floppy drive and capturing that well. but now we're a little curious of how folks are going to use this if floppy drives arent available. we had to pay a pretty penny for this drive, second hand, and that makes it tougher for more folks to get drives and use them to read floppies.
we did have a USB floppy drive (originally ordered to read out our mavica camera images) and now we're curious how it works so we opened it up! inside is a samsung SFD-321S which is we'll take as the "S"MT version of the SFD-321B datasheet we read earlier. (we couldn't find a datasheet for this 'S version tho).
Instead of the 34-pin IDC there's a 26-pin 1mm FPC connected to a cheapy adapter board with a single sanded-off 28-tssop chip. the chip is handling the Mass Storage - FDD conversion all on is own. but it's too smart for us! we don't want MSD, we want those delicious flux transitions.
thankfully this nice person posted up the pinout for us https://jestineyong.com/examining-and-testing-a-small-universal-fdc-to-usb-adapter/ and when we probed the index and data lines while accessing the disk, we found nice MFM traces coming out. next up we're going to design a quicky adapter from 26-pin FPC to 34-pin IDC pin header & breadboard. (we did find some converter PCBs but all going the opposite way!)

OK so part 1 we got our wiring worked out and found an index pulse. Part 2 is we started getting MFM data coming out. Now we're capturing pulses with gpio bitbanging, and storing all the pulse widths in a large memory array. each track has a 500Khz signal, and outputs data every 5 Hz, so we have a max of 100K samples worst case.
since we're using a cortex arm with 192K~256K of RAM (the RP2040 has 264K!), its no biggie to store all the pulses in an array. here we are reading track 1 and binning the pulses: we're seeing three pulse width bins stand out, about 40 count, 62 count and 85 count. but there's also a couple ultra short pulses (25 count) and an ultra long pulse (~200 count).
each count is about 48ns-ish so that translates to 2us, 3us and 4us bins, with a few 1us and one or two 10us+. not exactly sure whats up with those outliers. do we ignore them? are they start-of-data markers? We also noticed that track 0 has way more unusually long or unbinned pulses, like almost 100 different values. its a little mysterious, we'll have to investigate if there's something special about track 0!

OK now that we've gotten the motor up and running, and the drive selected in step 1 - we know our wiring is correct. step 2 is getting data out! unlike almost all protocols we're used to, there's no clock pin on floppy data. it comes out in MFM format (at least, this floppy disk format does) which means we get a series of ~500kHz open-drain pulses with short negative widths, and varying positive widths that indicate flux transitions. now the proper thing to do here is use a PLL to sync up with the pulses since the motor speed can vary a few %, then convert the pulse widths to bits of data. but we're gonna do it dirty to start, and just busy-poll the pin using a fast register gpio read and collect pulse widths, then maybe decode and bitpack them on the fly. not sure if this is workable yet, but it looks OK so far: just started collecting the data pulses and they seem to be binnable.

Music by Bartlebeats https://soundcloud.com/adafruit
If there's one thing we believe in strongly here at Adafruit its that if you have an embedded interpreted language running on your microcontroller, it's super important that you can access floppy drives from it. Sure, sure, you could use a micro SD card, but microSD cards can get lost easily compared to a chonky 3.5". So we're starting to look at how to get a floppy drive up and running. The good news is you can use 5V power and it seems to be ok with 3V logic levels. We've got the idc cabling wired up right we think, because we can now turn on the motor and see index pulses coming out at around 5Hz. This Samsung SFD-321B datasheet has been really helpful in interfacing, and so far our code is in Arduino since we're comfy with that for hardware noodling. We'll publish it as a cross-platform-usable open source hardware so folks can keep on spinnin'.

Ooh its the end of the year, a very liminal time as it were! We are keeping warm and well-fed while wrapping up some projects. We got our Scorpio PCBs in, but we're still waiting on our 8-bit level shifter chips before putting em together. We also are working again on our Feather M4 Adalogger board. While doing so we started working on some Learn guide templates for Arduino, particularly since we're doing more low-power or 'unusual' configurations for our hardware and it can be a little odd to get onboard hardware working. The Learn guide templates are kinda interesting so we thought we'd show how they work!

This week's EYE ON NPI is so flexible, it's thinking of joining the Rockettes (https://www.rockettes.com/christmas/)! It's TDK's BCS Series Low Illumination Film Solar Cells that are designed for direct integration of products, particularly wearables or credit card size and thickness electronic components. This amorphous panel comes with 6 cells, each about 0.4V open-circuit, for a total of about 2.6V output and 30mA. The nifty part about this panel is just how incredibly thin it is - only 0.2mm which means it can be bonded onto almost any surface or device. And unlike most panels that are made of monocrystalline cells, it is ultra flexible and will not crack or break.
TDK's BCS series are thin, lightweight, and flexible solar cells offering high power generation efficiency under fluorescent and LED light sources. The cells are made of amorphous silicon film substrate, and designs can be customized according to various shapes and applications. Because BCS series solar cells offer output stability in low and dim light, they are suitable for use in products used indoors. Additional benefits of solar cells include cost reduction in electrical wiring and battery replacement. When used in combination with a primary battery, solar cells can extend battery life and usage time of rechargeable devices. BCS series solar cells can be used in applications such as watches, wearables, beacons, wireless sensor nodes and other IoT power supply applications, smart cards and locks, and more.
Compared to many other ultra-low power source harvesting techniques (https://en.wikipedia.org/wiki/Energy_harvesting) like vibration/piezoelectric or heat, solar is very efficient, very small and very easy to use. Amorphous cells are a great option for folks who want to have indoor-powered electronics without hassle. Simply connect the two terminals to you circuitry plus and minus: when there's ambient light, you'll get voltage output.
These panels may look familiar if you've ever had a solar-powered calculator (https://en.wikipedia.org/wiki/Solar-powered_calculator) - often times you'd have to hold these up to a lamp to get them 'kick-started'. Those pocket calculators with LCDs are a great example of ultra-low current draw electronics that could run off of a tiny cell, we're talking under a milliamp here. That's something to keep in mind when integrating panels, they produce about 1/10th of the power folks think they do!
The biggest challenge that folks have with implementing solar panels is that they don't really act like a true voltage source or current source: they're somewhere in the middle, like a negative diode. With solar panels, the voltage and current vary constantly depending on sunlight available. They are unstable! That instability confuses electronics battery chargers, which causes them to do one of two things: rapidly turn on and off as they try to draw more current from the panel than possible and/or draw much less current than they can, to keep the voltage from collapsing. So you've got a few choices for implementing this panel: 1) have electronics that is OK with a widely varying input voltage: about 2V to 5V max, and will brownout safely when light disappears all of a sudden. Then, make sure it uses less than a few mA of current so that it doesn't collapse the IV curve by drawing too much power
2) use a super capacitor or rechargeable battery of some sort, that is trickle charged by the panel. once the voltage on the cap gets to a certain amount, the circuitry can use that to perform whatever calculators or data transfer required.
3) use a smart energy-harvesting chip like the LTC3588 (https://www.digikey.com/en/products/detail/analog-devices-inc/LTC3588EMSE-1-TRPBF/2216345) to manage the load on the panel and either charge a battery or directly power electronics with a cleaner supply than directly powered from the solar cell. Sometimes these chips can even operate as a MPPT charger (https://en.wikipedia.org/wiki/Maximum_power_point_tracking) to get the very max power possible. If you're interested in adding a super-flexible and ultra-thin green power supply to your next design, check out the BCS4430B6 (https://www.digikey.com/short/vwm3z35j) and friends. The TDK BCS Series Low Illumination Film Solar Cells (https://www.digikey.com/short/vwm3z35j) are in stock right now at Digi-Key for immediate shipping! Order now and you will be relaxing in the sun by tomorrow afternoon.

Ladyada's desk is jam packed with goodies :) first up, we're trying to always order the tester PCBs when we get our panels in, so we don't have to mill out a prototype on the bantam unless something goes amiss. this is a 'drop n beep' tester - where it repeatedly attempts to test and then beeps/blinks on success. the production team loves these kinds of testers.
then, we got some 'pantone chips' made of PCB material with copper underneath, from our board house, to match the PCBway pink. this is so we have two sources of PCBs - we've been seeing lockdowns take out some of our suppliers lately! this is Pantone 204 C (hex #E782A9). nice color right?
don't forget, you can STILL get a free pink Feather RP2040 when you order $99 or more from adafruit.com - https://www.adafruit.com/product/5299 we will run out in a few days so don't wait too long!

For the SCORPIO Feather, we need to buffer 8 outputs for NeoPixels from a 3V signal to a 5V signal. The '245 is the transceiver we have traditionally used - but we need a very smol chip, that can also handle if the logic level is 3V and the power supply maybe gets towards 5.5V, thus getting dangerously close to 1/2 VCC.

Lots of people don't like to admit when they make a mistake - but we love to share our 'happy little accidents' so folks can learn from us! We had ordered PCBs for the ESP32-S2 TFT Feather and realized right before going into production that while we were depowering the I2C power (to turn off external sensors while going into deep sleep, for example) we still have the I2C pullups enabled...this caused higher current due to the back-powering leak. Woops! But hey, we either win or learn something. So here's a quick re-spin we did to verify we got it right this time. The PM2.5 is a massive I2C device, and here we are going into low power and deep sleep for one second each, to verify that we are hitting that 80uA in deep sleep for sure. Now we're ready to book the PCB!

We're back from visiting family, but we do have some goodies on our desk to show off. One is our ESP32-S2 TFT Feather did get wrapped, we wanted to make sure our low power mode is right - we made a mistake with the pullups on the earlier version. We also have a new Feather we finished designing with the code name SCORPIO!
The Great Search - 74AHCT245 Small 3V to 5V logic level shifter https://www.digikey.com/short/85jj2p04
For the SCORPIO Feather, we need to buffer 8 outputs for NeoPixels from a 3V signal to a 5V signal. the '245 is the transceiver we have traditionally used - but we need a very smol chip, that can also handle if the logic level is 3V and the power supply maybe gets towards 5.5V, thus getting dangerously close to 1/2 VCC. We'll show why the T is important!

OK so to get the QT Py manufactured we need a tester. In this case we're not going with a teensy or arduino because the fastest way to program an esp32-s2 (we've found) is with the compressing stub loader that esptool.py uses. also, we're going to be doing a wifi signal test where we scan on the Raspi for the ESP's access point - this is a simple but effective way to make sure the antenna is on right. the tester python code runs on the pi, with a pitft for colorful text output and buttons to start test. another great example of using your own tools to make tools that are used to make other tools!

This week's EYE ON NPI is PIRfect for adding human-motion detection to your product or project - it's Panasonic's new PaPIR sensor line-up (https://www.digikey.com/en/product-highlight/p/panasonic-electric-works/ekmb-ekmc-series-flat-square-lens-type-pir-motion-sensors), featuring ultra-low power current consumption, a jaunty square shape, and multiple color options so your sensors will be detecting in style.
PIR sensors are great for detection motion of humans and other large & warm things. They are particularly excellent for making your designs use less power / be more 'green' because you can detect when a person walks into the room or in front of your control panel: so monitors or lights can be disabled or dimmed when there's no people around. Or your thermostat will know that it doesn't need to turn on the AC or heat since nobody is at home. And it does this all without video cameras, face detection or cloud computing (we're only being slightly sarcastic here!)
The PIR sensor element itself has two or more slots in it, each slot is made of a special material that is sensitive to IR. The two slots can 'see' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves. When the warm body leaves the sensing area, the reverse happens, whereby the sensor generates a negative differential change. These change pulses are what is detected.
The Panasonic PaPIR modules (https://www.digikey.com/en/product-highlight/p/panasonic-electric-works/ekmb-ekmc-series-flat-square-lens-type-pir-motion-sensors) take a full circuit board's worth of PIR support components and tuck them all into the metal can that fits beneath the plastic lens of the sensor. Since it is fully integrated, you only need to solder in 3 wires: power, ground and output for instant detection up to 5 meters away.
There are other PIR sensors available, but they tend to be kind of large and are hard to integrate into a design directly. (https://www.adafruit.com/product/189) - they're best for maker projects not necessarily products. The EKMB/EKMC designs from Panasonic brings a very compact and ultra-low power solution for when you want a small 5 meter-range PIR sensor that can be soldered directly to a board. And the power draw is super low - about 1~20uA, so it can be used for battery powered products. Since it's so low power, you could connect the output pin directly to an enable pin for a power supply or to a transistor for turning on power to lights or a buzzer. Note that the ambient current draw will affect the stability warm-up time and the sensitivity, so you'll probably want to try different ones in-situ to see the minimal current draw you can get away with.
PIRhaps you're interested in picking some up? Well, today is your day cause Digi-Key has all the different sizes, colors and sensitivity options available for purchase right now in stock! Visit the Panasonic EKMB/EKMC Series Flat Square Lens Type PIR Motion Sensors feature page (https://www.digikey.com/en/product-highlight/p/panasonic-electric-works/ekmb-ekmc-series-flat-square-lens-type-pir-motion-sensors) to place your order today and you will be able to add ultra-low-power sensing by tomorrow afternoon.

We've gotten a lot of requests for a MCP23017 breakout and we've always sorta been like "ehh why not just use the DIP chip?" but with STEMMA QT we could see the use case for a plug and play version that comes with all the passives on board. so this breakout has 16 GPIO with matching ground pad. each gpio can have pullup, with 3 address pins, 2 irq pins, runs on 3 or 5V power and logic. we think this board is kind qt!

This week's Great Search is about learning from mistakes - in this case I ordered the wrong ESP32-S2 chip for the QT Py S2, because I wasn't paying attention to all the variants. This is where it pays to check the Espressif datasheet for the specific chip naming especially since sometimes the part marking isn't clear. We recommend looking over the product selector at https://products.espressif.com/#/product-selector?language=en before booking your order - check the Flash, PSRAM and temperature offerings!

We had a smashing week of getting through some older prototypes. First up we have revised our CP2104 breakout to use the CP2102N as we covered last week, its the next 'generation' of Silabs usb-serial chips. Our rev B of Feather M4 adalogger is in, and we think we've got this one ready to ship. Finally we also got our 4-layer QT Py ESP32-S2 boards in and put together a prototype to verify the boards came out right (its our first 4 layer).

This week's EYE ON NPI is like a Vulcan: no, it doesn't have pointy ears, but it is totally logical! It's the Crouzet Millenium Slim Ultra-Small Logic Controller. (https://www.digikey.com/en/product-highlight/c/crouzet-usa/millenium-slim-ultra-small-logic-controller) It's the darn-cutest looking logic controller we've seen, with wireless BLE programming support for 4 inputs and 4 outputs.
Each controller is very small compared to large PLCs, with 4 inputs and 4 outputs. There's a version with 500mA transistor sourcing outputs which can do PWM output, and two relay versions - one AC powered and one DC powered. Each input can also be PWM input and some can be tachometer or analog inputs. There's no LCD or TFT display - instead you can use a phone with iOS or Android to connect to the BLE interface to analyze/debug the output, and provide buttons for input if a UI is desired.

The nicest part of this product is the programming interface software. (https://www.crouzet.com/products/automation-controllers/software/) The software only runs on Windows that we could tell, but it's a simple drag-n-drop flow-based programming kit that lets the operator come up with simple logical operations that can be combined to create advanced control flows. This is a bit different than microcontroller programming: all the logic executes at the same time, so perhaps it's a little like a cross between block-based coding and FPGA/CPLD coding. There are some simple commands like Boolean logic, or simple counters - to more advanced ones like PID controllers, timers, or Schmidt triggers. Even though this is like a 'baby' PLC, it seems like the programs can be simulated/shared from smaller to larger controllers.
The BLE connectivity is handled with a BlueGiga dongle (https://www.silabs.com/wireless/bluetooth/bluegiga-low-energy-legacy-modules/device.bled112)- this is a device that presents itself as a serial COM port and then takes commands over UART data to connect and transfer BLE data. This might seem a bit odd given that Win 10 has native wireless support - but probably a good idea since native BLE connectivity is really tough on desktop. There's also a better chance that the programmer could run in an emulator because the driver is generic.
We think the Millenium Slim Ultra-Small Logic Controller could be an excellent first-time-PLC for someone starting out with PLC, or anyone with a small automation project where a big controller is overkill. Best of all, both the BLE dongle (https://www.digikey.com/short/ct5hqv07) and PLC (https://www.digikey.com/short/2jfv2p4d) are in stock right at Digi-Key for immediate purchase. So whether you are an expert automator, or a beginner mechatronist - purchase today and you can get it in your hands tomorrow morning!

We use the cp2104 usb-serial converter in a lot of our designs - but it's hard to get during the shortage(s). The cp2102n is available, and it's a clooooose replacement but theres a few small hardware changes needed and the internal eeprom is different. So, if you just spent 2 days trying to figure out why your cp2104 eeprom writing code isnt working and you were dreading having to rewrite the libusb vendor calls, good news! This pr to a fork of a program compiled cleanly and did the job a treat on our raspberry pi tester. https://github.com/irrwisch1/cp210x-cfg/pull/1 whew :)

0:00 Getting started and hellos 3:28 Housekeeping 6:24 Is the flash needed less on those CP targets without USB ? 7:28 sleep update 11:00 Hi Scott - got a ? on the nrf52 bootloader and where/who should set the bootloader config regarding the CRC check and setting the bit for "app valid" bit in the bootloader config register of the nrf52xxx Should it be done at the bootloader and set it to assume a good app? or should it be done at the application level where the crc might be computed and flashed at the same time as the application. Perhaps Thach would know more… 21:47 Pi Zero 34:38 NeoPixel on RPi 41:37 Firmware Debugging and Development Tools for projects and contributing to CircuitPython https://www.adafruit.com/explore/firmware-debugging-and-development 52:58 Back to neopixel 1:16:33 Where does the Neopixel code live in CircuitPython? 1:20:20 Start implementing Neopixel for the CircuitPython RaspberryPi port 1:30:19 Q: I can’t build today’s CircuitPython latest. Scott: A good place to followup is in the #circuitpython-dev channel on Adafruit Discord or open an issue in GitHub. 1:30:52 Back to implementing Neopixel 1:40:36 What speed should data be sent to the FIFO and how is that controlled? 1:42:22 Let’s see if it builds and works! What could go wrong? 1:44:35 Oops. First a code.py that uses the Neopixel needs to be on the Raspberry Pi 1:46:16 Setting up Salea Logic analyzer for neopixel to monitor the Raspberry Pi 1:47:16 It didn’t work, debugging 1:48:03 Todbot: That neopixel analyzer is pretty cool! 1:49:30 print debugging in CircuitPython 1:54:40 Q: Will CP for RPi understand HMD_cvt and HDMI_drive in config.txt so I can configure a 5 inch HDMI LCD from Waveshare? 1:55:26 Back to the broadcom data sheet and debugging continues 1:57:24 Wrapping up and Goodbye for 2021. Next Deep Dive is tentatively on 7 January 2022. Happy New Year! 2:01:40 Kitteh !

A long time ago, in a galaxy far away, there were computers that came with DE-9 serial ports that would let you read/write 8-bit serial data on two lines. Those days are gone, now we have USB only. Many modern chips have a built in USB native peripheral so you can connect to a computer, but there are still lots of chips that don't! In that case, you'll want a converter chip. Let's see what is available in the market and some things to watch out for when spec'ing them.

This week's EYE ON NPI is easy-peesy-lemon-squeezy, the simplest way to add LTE cellular data connectivity to your product or project with Blues Wireless Notecard Cellular Modem System-on-Module (https://www.digikey.com/en/product-highlight/b/blues-wireless/notecard-cellular-modem-som).
These M2 cards come with 4 different cellular module types for global coverage on the LTE Cat 1 or Cat 1M (with backup CDMA and GPRS options). Each card slides into one of many different add-on boards that make connectivity to a Feather or Raspberry Pi foolproof.
Blues Wireless' Notecard is a tiny 30 mm x 35 mm SoM device-to-cloud data pump. A Notecard purchase includes 500 MB of data that is usable over 10 years with the ability to top-up as needed. Connectivity is globally available in 136+ countries. The Notecard features an m.2 connector for embedding the user's board. As an embeddable SoM, the Notecard can be used with any microcontroller (MCU) for greenfield and retrofit projects using the user's design or one of Blues Wireless' custom-designed Notecarriers.
With two lines of code, users can send data to the cloud in minutes without complex device registration or provisioning required. With a powerful JSON-based API, the Notecard can be programmed over USB or controlled from the preferred MCU or single-board computer (SBC) using one of Blues Wireless' open-source firmware libraries. Connect from the preferred host to the Notecard using Serial or I2C. The Notecard is designed to work with a cloud service for ingesting and processing device data. Notehub.io provides secure device connectivity, project, and fleet management, as well as simple routing to third-party cloud services. Alternatively, the user can host their device service based on Blues Wireless' open-source reference implementation.
The Notecards use Quectel cellular modules, which are low cost and have been used for many years so they're very reliable. Depending on your location, you may not have LTE coverage yet (or LTE Cat M/M1) so do check your coverage maps and rollout plans - there's versions with GPRS (2G) and CDMA (3G) backup capabilities. The cellular plan itself is handled by Blues and is handled by AT&T, so no external SIM is required - although there is a insert spot for one if desired. Each module is bundled with a 10 year, 500MB cellular plan, which can be customized if needed. 500MB doesn't sound like a lot, but if you're using MQTT for sending data reports, where each packet is only a couple-hundred bytes max, it will last a long time. Check AT&T's coverage map to know which module you'll need to use for your area (https://www.att.com/maps/wireless-coverage.html)
We particularly like the M.2 module design idea - it makes insertion very easy and doesn't allow for flipped boards or bent pins. Swapping out different modules can be done in a post-manufacturing step or as an add-on upgrade situation. It also means as cellular networks are upgraded and retired (which happens every 5~10 years!) the module can be changed over. If you need to source an M2 connector - Digi-Key has tons of those in stock too (https://www.digikey.com/short/zn1q8z), just make sure you get E-key type. These contacts are under a dollar a piece and come on tape-and-reel for easy pick and placing.
The modules are designed for end-use cases. While prototyping you may want to use their handy "Notecarrier" breakout boards (https://www.digikey.com/en/product-highlight/b/blues-wireless/notecarrier). Each one can use any of the Notecards, so just mix and match as desired. There are ones for battery usage, Raspberry Pi HAT, and Feather breakout. (https://blues.io/products/notecarrier/)
And best of all, all of the Blues Wireless Notecards and carriers are in stock right now at Digi-Key! (https://www.digikey.com/en/supplier-centers/blues-wireless) Pick up any combo you need to start prototyping your design immediately. You can get started with Blues' tutorials and code snippets (https://github.com/blues) - they promise you'll be sending data in under 30 minutes. Order today and you can be sending data over cellular by tomorrow morning.

Ahh one of the first breakout boards we ever made for sale at Adafruit is the ADXL345 - such a classic triple-axis from ADI! This ol' girl could do with a makeover, so we're re-doing the board as a Stemma QT compatible. Now it will be plug-and-play for any platform for rock-solid reliable accelerometer data over I2C or SPI. Thanks Analog Devices!

We had a nice long weekend with tasty food, hanging out with friends, and doing electronics! one thing we got around to finally was finishing a QT Py that is based on the ESP32-S2. Yeah this is many months old but we also wanted to wait till we could get the version of the chip with PSRAM built in. We're doing Arduino & CircuitPython tests now. Design is ready to go with a nice silkscreen :)

This week's EYE ON NPI knows where it's been and where its goin'! We reckon you'll love the ST Teseo-VIC3DA and Automotive GNSS Dead-Reckoning Module and Eval Kit (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/teseo-vic3da-automotive-gnss-dead-reckoning-module), a technology that improves on GPS/GNSS by adding an IMU and odometer to help determine location in places where GPS signal is unable to reach such as tunnels and canyons.
We've covered GPS (https://en.wikipedia.org/wiki/Global_Positioning_System) modules before on EYE ON NPI - they're many-decades-old technology that uses a satellite constellation to calculate 3D location on Earth with ~10 meter precision. They're great for use with cars or trucks because GPS works anywhere on the planet, and when combined with digital maps can easily calculate instructions, arrival time and recommended routes. However, GPS has a few things that it can't do. Most important is it cannot work at all if there's no clear view of the sky. One needs to constantly be receiving GPS data from 3+ satellites in order to determine location. So, if you're in tunnel or in a city-made canyon (http://wikimapia.org/6909209/Canyon-of-Heroes), or if there's RF shielding or interference, you simply 'drop off' the planet. Super awkward!
For those situations, some companies or technologies can take advantage of "WiFi Assisted GPS" (https://link.springer.com/chapter/10.1007/978-3-642-13618-4_14) this is where a secondary base station, or WiFi signal names, can be used to help locate during low-visibility. This works particularly well in cities, of course, where there's a high density of AP names that don't change. But it's still pretty useless in a tunnel or outside a city center. There's also RTK, (https://blog.adafruit.com/2020/06/08/eye-on-npi-u-blox-c099-f9p-application-board-for-zed-f9p-gnss-rtk-module-eyeonnpi-adafruit-digikey-digikey-ublox/) which is awesome for increased precision and accuracy - but that requires a base station within a couple-hundred meters, and another transmission link on every device, so while it's used for some agricultural robotics, it's not always possible to implement (but it is worth investigating if you can control the environment where you're using GNSS.)
So, finally we come to dead-reckoning techniques(https://en.wikipedia.org/wiki/Dead_reckoning). These work in an intuitive way: if you know where you last were and you count the number of steps and direction which you're going, then in theory you should be able to determine your exact location. Now, historically this technique has been used with boats and planes and hiking - in fact you probably learned it in scout camp. (https://en.wikipedia.org/wiki/Dead_reckoning#/media/File:CYA_Coastal_Navigation_With_Dead_Reckoning_2.jpg) And, while in theory it should be a perfect way to determine location, the implementation makes a massive difference on how usable the end product is. A slight error in direction angle makes for more and more drift error in the final result - and as humans struggle to calculate direction, it's better than nothing but not necessarily trustworthy without having reference checkpoints on a map. For this module, ST has worked on how to make it easy as possible to implement dead reckoning into your robot, with all the fixin's. First up, you're getting multi-constellation support. So not only American GPS, but also Europe's Galileo, Russia's Glonass, Japan's QZSS, and China's BeiDou systems. So if you can't get data from one constellation, you can use another. Next up, there's an internal 6-DoF sensor that is used as a tilt-compensated compass that will determine direction precisely. (GPS modules do give 'heading' but its just based on the last few locations). Next you need to calculate 'steps' - that's done with an odometer input. That pin is connected to a simple rotation-count sensor and direction sensor that will let the chip know how many ticks have passed since the last known fix. You can also send the odometer data over NMEA commands, btw. Finally, the module can combine this in the TESEO firmware to give you a fast (30 Hz) updated location! Usually this calculation stuff is the hardest part of doing dead reckoning so its really cool to see this all in one
ST makes a very snazzy EVB-VIC3DA dev kit in an aluminum box and everything, (https://www.digikey.com/en/products/detail/stmicroelectronics/EVB-VIC3DA/15276423) with ports and power supplies and LEDs so you can immediately toss it into your robot without any soldering or board layout required.
The ST Dead-Reckoning GNSS modules TESEO-VIC3D (https://www.digikey.com/en/products/detail/stmicroelectronics/TESEO-VIC3DA/15276424), and EVB-VIC3DA eval boards (https://www.digikey.com/en/products/detail/stmicroelectronics/EVB-VIC3DA/15276423) are in stock right now, for immediate shipment from Digi-Key! Order today and I reckon' you'll be adding this great locating hardware to your design tomorrow afternoon.

This ESP32-S2 QT Py is so smol i just wannna pinch its lil cheeks! on the back is and ESP32-S2 with 4 MB Flash and 2MB PSRAM all stuffed inside this QFN chip. we verified Arduino works last night. So today we've been testing out CircuitPython support. Here's an Adafruit IO demo that sends sensor data from plug-n-play QT boards over MQTT to a dashboard. this demo has been runnin all day flawlessly. Just a few more tweaks to the design and silkscreen before we send off the PCBs - what color should we make this board? :)

OK we're going to be fabbin the KB2040 board tomorrow! Yay PCBs arrived and we've got all the parts. Last thing I have to do for the team is hand off the tester. Over the weekend I've been doing a few testers over and it started getting annoying how much copypasta we have in our testers. So I wrote a Testbed library that sort of encapsulates a lot of the common code that is reused over and over.

This week's EYE ON NPI is clicky-clacky with Johnson Electric’s range of linear DC solenoids (https://www.digikey.com/en/product-highlight/j/johnson-electric/linear-dc-solenoids) in various sizes and voltage ratings.
Solenoids are a nifty type of motion control element - most folks think of motors or servos when thinking about motion control (and Johnson Electric does make motors too) but motors and servos are best used for rotation motion. You can convert them to linear motion but usually you need to gear them down a lot to get a reasonable torque - force conversion. Some use a rack-and-pinion mechanism (https://learn.adafruit.com/rack-and-pinion-bot/overview) or a drive/lead screw (https://en.wikipedia.org/wiki/Leadscrew). Solenoids provide a very easy to create a short but powerful linear force that is either on or off - you can't really be 'in the middle' of a solenoid actuation.
Solenoids all work in the same basic way: there's a toroidal coil of copper that forms an electromagnet. (https://en.wikipedia.org/wiki/Solenoid) As current is passed through the coil, it pulls the ferrous slug into the coil with near-instant force. When the power is released, the electromagnet de-powers and the slug can move freely. In this sense, all solenoids are pull-type. Sometimes, there's a return-spring that will pull the slug out to 'reset it' - these are push-pull type (https://www.adafruit.com/product/413) - but most solenoids, including these from Johnson, don't have the spring. Usually, whatever the solenoid is installed in provides the return pressure.
Most solenoids we've seen are rectangular style, which tend to be sort of 'candy bar' shaped. The Johnson solenoids are more 'pancake style' - with a flatter and wider design that has less requirements on depth. (https://www.digikey.com/en/product-highlight/j/johnson-electric/linear-dc-solenoids)
Johnson makes a couple dozen of different solenoids with different voltages and sizes, we picked up two and one was about the size of a grape and the other the size of an orange. Common voltage ratings are 12V and 24V - the amount of current will vary with voltage since you still need the same amount of power per coil size. Usually the voltage is whatever the equipment is set up to provide. Note that solenoids require a lot of current, many amps whenever activating! Thankfully the power does not have to be very clean, so you can have a separate regulated supply just for your motion control.
Finally, the Johnson Electric YouTube channel has a cool series of videos called "Interviews with Old Timers" where they interview employees that have been there for 50+ years, to hear what it was like when Hong Kong was first beginning to do manufacturing. (https://www.youtube.com/watch?v=JyzoR-XtR6M) There's some great historical information in there, we had a lot of fun watching them and looking at the old photos.
Digi-Key stocks a full range of compact solenoids from Johnson Electric available for immediate shipment. (https://www.digikey.com/en/product-highlight/j/johnson-electric/linear-dc-solenoids) Be sure to check the datasheets for the specs and sizes, as there's quite a range in size/voltage/actuation force! We picked up 2024-1026-ND, a chunky 12V one (https://www.digikey.com/short/40dmhdhj), as seen in the EYE ON NPI video, it's a real beast. Whatever size you need, if you order from Digi-Key today , you can be electro-magnetting by tomorrow afternoon.

Silicon shortages have been famous for the STM32 and ASIC droughts, but even simple mosfets have been harder and harder to find. For our PropMaker FeatherWing, we use 3 high current FETs to drive a 3~9W LED, and what used to be a near-jellybean part now needs a replacement!

Oooooh we are SO CLOSE to releasing wippersnapper I2C support! Lots of IoT platforms support analog or digital I/O - but the real stuff is in I2C sensors. We've started adding the scaffolding for I2C sensor support on the staging wippersnapper server. Here I've got a FunHouse board, connected to 'wipper, and when we go to add components there's an AHT20 part available! Next, the server requests an I2C scan to verify a valid address is on the bus, and once we create the component, two new feeds appear: one for temperature and one for humidity. Look at how fast it is to add sensors to an MQTT feed with no code whatsoever!

ESP32-S3 mini modules make for an easy 'S3 Feather
We just picked up some ESP32-S3 Mini modules from @digikey and, surprise! They are pin compatible with the S2 Mini modules. That means we were able to upgrade our ESP32-S2 Feather to use the newest dual-core+BLE chipset. All the pins have been tested, NeoPixel works and so does I2C. I guess that means we can fabricate some of these for the shop as soon as we can get a reel from Espressif

Last week we wrapped up the ESP32-S2 feather, and they're in the shop now. We made two versions, one with and one without a BME280 enviro sensor. Next up we'll do take 2 of this board, the TFT Feather - we've tested Arduino on it so now its time for CircuitPython. Our first attempt at the board definition has slow TFT redraw for bitmaps but we can fix it! Next we're adding some low power tweaks to make folks who want to have small quiescent power happy. There's also a new ESP32-S3 mini module engineering sample available, this chip is going to be the next big release from ESP and it has some nice improvements over the 'S2

Silicon shortages have been famous for the STM32 and ASIC droughts, but even simple mosfets have been harder and harder to find. For our prop featherwing we use 3 high current FETs to drive a 3~9W LED, and what used to be a near-jellybean part now needs a replacement!

On Tuesday we tested this board with Arduino, now it's time for CircuitPython! We just did a PR to add the TFT support so it comes up with the REPL automatically https://github.com/adafruit/circuitpython/pull/5570 and its kinda cute! for our testing demo we're running our github 'starts' fetcher https://learn.adafruit.com/pyportal-github-stars-trophy/code-pyportal-with-circuitpython - its a fast way to test filesystem, image rendering, wifi, and ssl all at once. works a treat! we're close to getting this board into production, coming soon to the adafruit shop :)

This week's EYE ON NPI is like a good winter coat - waterproof, super rugged and looks great while doing it. This week we're back with another C&K Components product (https://www.digikey.com/en/supplier-centers/ck-components) : what can we say, they make some great items, and best of all they're not affected by the silicon shortage, so they've got lots of parts in stock!
The MPSR series from C&K are ruggedized magnetic proximity sensors, perfect for automotive sensors and indicators, industrial sensors, anti-tampering and other security and factory automation equipment. The MPSR series sensor and magnet are both sealed in a tough aluminum housing combined with stainless steel wire sleeves. This housing protects the sensors from the harsh environments they are commonly used in, whether oil, water, grease, or volatile chemicals and gases. Manufactured for quick and easy installation, the MPSR series also have a long-life cycle – lasting for more than 4 million actions – and a robust 30 V, 3 W rating.
We're suckers for beautiful, rugged sensors and enclosures. A lot of times folks use Adafruit parts for prototyping a design and then have to deploy it to The Real World where things get damp, dirty, and dusty. Where dogs or rodents chew on your cables, where coffee is spilled, where folks doing construction go "oops". Just last weekend, we met someone who does museum exhibit design (https://jobs.adafruit.com/job/exhibit-fabricator-iii/) - which is known amongst engineers as one of the hardest construction challenges (https://jobs.adafruit.com/job/exhibit-maintenance-technician/) because not only does it have to last 10 years but must do so while getting abused 12 hours a day by absolutely adorable children who are super interested in finding out just how hard they can yank or punch something.
So when we saw this NPI show up on https://www.digikey.com/en/new-products, we decided to highlight it as what we recommend for folks who want to take their designs to the next level. So, yes, please start your design with one of our low cost magnetic reed switch sensors (https://www.digikey.com/en/products/detail/adafruit-industries-llc/375/6691113), but when its time to do your final install, the C&K MPSR rugged magnetic proximity sensor will survive any kind of environment with IP69 rating (nice). We love the metal coil sleeving and the potted epoxy body. Other than being super swole, it works just like any other magnetic switch, with SPDT contacts so you can use it in NO or NC situations.
Best of all, the C&K MPSR rugged magnetic proximity sensor is in stock right now for immediate shipment, (https://www.digikey.com/short/8m53pn88), so order today and you can be ruggedly sensing by tomorrow!

This variant of the ESP32-S2 Feather board comes with a TFT on top, it fits perfectly with room for some LEDs and two buttons on the top side. The bottom side has the ESP32-S2 mini with 4 MB flash and 2 MB PSRAM and support circuitry. For example, we have a lipo battery monitor and a BME280 soldered on - the demo here is showing data from those sensors on the TFT. Just a few more tweaks and we can order this PCB!

Let's test two products at the same time! The OLED is 128x128 1.1" diagonal monochrom, and we've got it plugged into the other newp - a Feather ESP32-S2 with PSRAM. There's a cute lil vertical STEMMA QT connector in the middle which we can plug into to add more sensors and displays. There's also an optional BME280 sensor, for temp/hum/pressure sensing - so for this demo it's being displayed on the OLED.

For the STSPIN stepper breakout board, we need some current sense/limiting resistors. These are special resistors that are very low resistance but very high wattage, so they can dissipate the heat from the Resistance * Current^2. One thing we need to optimize for in this project is space over price - since the board size is fixed. So let's find the smallest current sense resistor we can, we might discover some interesting things!

Ahh we are trying to finish some older projects off, this week we put together a KB2040 which we designed earlier this year It's the same size and pinout as a Pro Micro - for use with keyboard projects like this DIY one https://1upkeyboards.com/shop/keyboard-kits/macro-pads/sweet16-macro-pad-white/ We generated a pinout diagram to help us verify the muxing is all right, and we'll maybe try to get it in pink!
The Great Search - Current Sense Resistors https://www.digikey.com/short/djch7b70
For the STSPIN stepper breakout board, we need some current sense/limiting resistors. These are special resistors that are very low resistance but very high wattage, so they can dissipate the heat from the Resistance * Current^2. One thing we need to optimize for in this project is space over price - since the board size is fixed. So let's find the smallest current sense resistor we can, we might discover some interesting things!

Break time's over, everyone! Time to build all those prototype PCB that have been kicking around. Tonight its the KB2040, a "pro micro" pinout compatible RP2040 board so that folks who want to use CircuitPython's awesome keyboard matrix and HID support can do so with existing keeb designs that were designed for 32u4 boards. There's lots of 0402's on this board so its fine work, but we were able to reflow it on our lil hotplate and both came up just fine! We'll post some renderings soon... it will prolly be a pink PCB :)

This week's EYE ON NPI is rockin' and rollin' - it's Suntsu's Rugged Foot Switches (https://www.digikey.com/en/product-highlight/s/suntsu/foot-switches). These switches are designed for use in guitar 'stomp box' effects pedals (https://en.wikipedia.org/wiki/Effects_unit), so they are very rugged and reliable with smooth activation.
Most of the time engineers are adding pushbuttons to a design, they're doing something like adding tactile switches such as these 6mm square ones (https://www.adafruit.com/product/367) or these panel-mount arcade switches (https://www.adafruit.com/product/3489) These buttons are available in a variety of different mounting types and sizes. however, they are still really only meant for use with hands or fingers (or noses!) - soft human bits with precision sensory feedback to keep from over-mashing the switch.
But sometimes our hands are busy and we need foot control. Most popularly, cars use feet for controlling speed and break so that both hands can be used for navigation or shifting. Or, sewing machines often have foot-pedal speed (https://www.adafruit.com/product/3739) and mode switches that use foot and need angle. Likewise sometimes electronic or mechatronic devices can benefit from having a non-'digital' input. Some folks may consider using voice activation but most folks feet are very adept and fast enough. The suggested uses from Suntsu are:
- Guitar foot pedals - Hey, by the way, did you know that Digi-Key has a whole section devoted to Guitar Parts? (https://www.digikey.com/en/products/filter/guitar-parts-accessories/1001) how cool is that?
- Sewing machines
- Tattoo guns
- Medical bed controls
- Soldering machines
- Industrial machinery controls
So while these fancy and durable buttons are famous for their guitar pedal use cases, they can also be great for any industrial / robotic uses where reliability and hands-free use is important. The first time we saw one of these is in a dictation system (where the person types and uses the switch to play and pause the audio).
These foot switches come in a few different configurations, but we're the biggest fans of the 2388-SSWFS-S01-AE11-HWH-C25-ND version with a JST XH connector (https://www.digikey.com/short/ccnp0780) for quick plug-n-play. And, if the switch does eventually get damaged, it's user replaceable. Bonus, our order even came with a matching socket connector!
All of the Suntsu foot pedal switches (https://www.digikey.com/en/products/filter/guitar-parts-accessories/1001?s=N4IgTCBcDaIMpwOoDE4Fo4AYCMIC6AvkA) are in stock now for immediate shipment - in this case it's a Marketplace product which means it will be shipped direct from Suntsu - we got ours in just a few days and it came in a cool packaging box with the motto "Helping tech companies create kickass products!" - and who are we to argue?

Ok! This is super fun, Scott is working on a port of CircuitPython that runs on "bare metal" on the Raspberry Pi. So of course I wanted to see what works with HDMI since we can show the REPL... and I happen to have an e-ink HDMI display. It's AWESOME.
One of the plans is to make a little computer with a keyboard, that is just CircuitPython. Write code, make art ... with HDMI, have the output go to a little portable projector... kids could make cool kaleidoscopes, or make a Haiku computer that shows the last one made when the power is off since this one is e-ink :)
Code is here for now, and watch Scott's Deep Dive each week at 5pm EDT on our socialz' for more!

Sometimes you've got some 3.3v powered circuitry and you just need a li'l bit of 5V power for some LEDs or to level shift to 5V circuitry power. You could go with a boost converter, but usually you need a diode, inductor, maybe even a feedback resistor set. If you only need ~50mA you may be able to get away with a charge-pump. These low-current boosters are not as efficient as DC/DC style converters but they are very simple and cheap, only needing a capacitor or two to 'double' the input voltage and then regulate it down.

We're finally getting back to all the seesaw boards we re-designed to use attiny817's now that the breakout and tester code for this family is done! Here's two designs, one is a slide pot + 4 neopixels. The other is for 'arcade buttons' with built in LEDs. We're mostly focusing on UI elements that can be used to make control surfaces. We're also trying to stick to a standard sizing so they all have similar mounting holes/shapes. We're really liking this family of chips, and have lots more QT boards we plan to design around it.

We designed a buncha I2C-to-whatever converters a while ago but got hit with the silicon shortage, so we're redesigning the boards with chips we can get. For example here is a I2C to slide pot + 4 NeoPixels design. Now lots of microcontrollers have ADC so you may not need a converter. But if you're using a SBC like a Raspberry Pi, adding analog inputs is a little messy, so you could definitely use something like this. Or maybe you just want an easy plug-n-play panel mountable slider. Either way, this code works great, and runs on an ATtiny8xy (e.g. '817 or '806) which we were able to get on the market.

Suggested https://codewith.mu/ 45:10 check out visual studion circuitpython plugin 47:11 Python 3.10 has deprecated “distutils”. Spent my day on that for Yocto Project. It’s nice to not need to worry with CP 48:00 rebooted to ‘lower’ resolution 48:30 flash wear discussion Nand flash, Nor flash, flash protocol 49:36 Should you have some knowledge of Python before learning Circuit Python? 50:00 Pi4 is ARM64....so theoretically you could port CPY to the M1 chip 50:32 core of CP is just like Python 50:57 SD Cards technical proprietary, but … 51:27 Why use bare-metal CP over blinka ( ease of setup, just does one thing ) 52:20 Implementation 53:11 adafruit_sdcard.py - SPI 1, 4 or 8 bits at a time 54:15 here is a lot of IO stuff that you couldn't do under a Linux kernel like bitbanging is quite hard/limited in a non realtime OS 55:16 raspi3-tutorial / 0B_readsector / sd.c 56:39 habits that lead to more reusable code :-) 57:04 declaring 5 global variables on one line with no comments 57:37 SBD generated structs vs. 58:05 multiple things on one line - suggest using curly braces freely 59:00 initializing some but not all variables ( on one line ) 59:26 ‘weird’ globals 59:39 q:is there a native async library in circuitpython? I found a library called "asynccp" it works for me now but it would be better to use the native way. 1:01:04 use single letter variables sparingly 1:02:06 perhaps run it through a formatter 1:02:18 “I still don’t know what this code does” :-) 1:02:55 consider naming style for global variables 1:03:15 ‘circle’ reference gighub rsta2/circle - well commented 1:04:10 check out the license 1:06:04 sdcard.org PDFs 1:06:44 Scott’s Pi Zero arrives on Monday! 1:08:11 640x480 HDMI raspberry pi bare metal REPL demo - last piece is SD card reading in CP - connect to USB mass storage 1:09:40 goal: read SD card over USB 1:10:29 Exception levels - switch from EL2 to EL1 ( os exception level ) CP is running EL1 1:12:00 Waiting for high speed to be merged into tiny USB 1:12:40 HDMI output used for display IO 1:14:40 Looking at board.c in CP ports/broadcom/boards/PI4 1:15:15 sdioio API 1:15:35 “with this big chonky font, CP needs to implement CBM ASCII to get cool map-building "letters"” 1:15:42 detour - fantasy console - mimic but modernize 1:16:34 nerd fonts project (nerdfonts.com) 1:18:00 Does circuitpython use Unicode strings? 1:18:14 Twitter emojis opensourced twitter/twemoji 1:19:44 displayio doesn't display it yet - though emoji variable names do 1:24:30 in cpython you can only use unicode characters in variable names if the belong to the "letter" class, so you can do accented characters, or Chinese, or Hebrew, but not emoji 1:25:37 back to sdioio/SDCard.c 1:27:54 second argument to SD send command - refer to adafruit_sdcard.py 1:30:50 SD Specs - commands , and back to adafruit_sdcard.py 1:39:03 bztsrc/raspi3-tutorial 0B_readsector/sd.c sd_cmd() / 32-bit commands vs BCM2835 ARM Peripherals.docx 1:41:21 Q: been experimenting with the sdcard module on circuitpython but it stops the code if there is no card in the reader 1:42:36 consider the response type ( number of bits ) 1:43:54 sdioio/SDCard.h 1:45:03 sdcard.org Part1_Physical_Layer_Simplified_Specification_Ver800.pdf r2 response codes 1:48:57 autogenerated SVD generated file bcm2711_ipa.h 1:52:45 sdcard.org Design Guide « Whitepaper » is a pretty cool resource. https://www.sdcard.org/cms/wp-content/uploads/2020/11/SD_Express_Design_Guide.pdf 2:04:00 CM4 Appendix B - ordering codes ( wireless, eMMC, RAM ) 2:06:15 Wrap up - next week Pi Zero on Friday 2:09:35 have a great weekend

This week's EYE ON NPI is a one-two-triple punch of awesome: its a combination prototyping breadboard kit from Twin Industries (https://www.digikey.com/en/product-highlight/t/twin-industries/combination-protoboards). Offering the best of three worlds in one: it has a gridded prototyping development area, a 'perma-proto' style 5-row DIP area, and a separate chunk of solderless breadboarding material for quick connections.
https://www.digikey.com/short/b44n2295
There are three versions of these combo-boards, each one is made of green-masked double-sided FR4 with gold/ENIG coating to reduce oxidation. The solderless breadboard chunk is bolted in place, but please note it does need to be soldered if you plan to use it, the bolt is not going to make electrical connectivity between boards.
Features Solderless, 5 holes per pad 0.1" x 0.1" grid of holes Plated holes: 0.037” diameter Lead-free PCB with gold plating: 0.062” thick 3 mm screw/nut is included to secure the module to board (additional soldering required) You can pick up Twin Industries combination protoboards over at Digi-Key today! (https://www.digikey.com/en/product-highlight/t/twin-industries/combination-protoboards) We're partial to OB1-LF (https://www.digikey.com/en/products/detail/twin-industries/OB1-LF/7423017) ourselves, but all three look good to us. They are in stock for immediate shipment, buy today and you can be prototyping in style by tomorrow morning.

We did an earlier Great Search on oscillators, but this week we're specifically looking at 32kHz 'real time clock/counter' crystals. These are often used in microcontrollers as input to a phased-locked loop (PLL) to generate a higher frequency internal clock that is more precise than an RC oscillator. Even though these are not 'semiconductors', they've been quite hard to source! Let's look at what options we've got.

Whew! We are going through all our Featherwings to verify that our ESP32-S2 Feather is ready to ship. Looking good so far, we've verified I2C and SPI pins using our TFT Feathers. One of the last tests is to check that the RGB Matrix Featherwing works, this tests a lot of pins! For a demo we're getting and displaying the number of GitHub stars the CircuitPython repo has, over 2,600!

It is starting to get a bit chilly out, with beautiful fall weather. We've even switched from iced to hot coffees! We decided this week to take a look again at our favvy Feather, the M4 Express. It's a good dev board, but there's improvements we can make given the years of experience we've had with designing Feathers. First up we swapped the Micro USB to USB C. We bumped the 2MB flash to 8MB, and added a STEMMA QT plug at the end. We also put a MicroSD card slot on the bottom, like our STM32 Feather. Finally, we made a few low-power-friendly improvements! We'll take a tour at the design in this stream The Great Search - 32 KHz RTC Crystals https://www.digikey.com/short/38nr3bdr

Or? 2:02:40 Is it still recommended for beginners to start with CircuitPython6? I've been finding some of the sensor examples provided don't work with CircuitPython7, as the calls/functions/etc have changed. 2:03:40 So big question...if I submit a PR that allows booty.py as code.py alternative if in Pirate language mode, will it be accepted? 2:04:10 eMMC and SDcard would behave the same, nothing to do there technically 2:05:00 Related question, is it possible for the community to offer pull requests to update those examples? Would that be best done on the particular sensors Github page? Which then would filter to learn.ada 2:05:59 Sooo running CP from a MultiGB SD Card will just work on the RPI? 2:06:50 Wrap-up - remember the US daylight time zone change happening soon - still at 2PM local Follow along at https://github.com/tannewt/circuitpython/tree/rpi 2:09:30 pet the cat

This weeks' EYE ON NPI is right on time, it's the ST VL53L5CX Time-of-Flight Ranging Sensor, (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/vl53l5cx-time-of-flight-ranging-sensor) the latest in a long line of successful and popular ToF ranging sensors. These sensors have gone through many revisions, and each version has improved on the prior one.
Starting with the VL6180X (https://www.digikey.com/en/products/detail/stmicroelectronics/VL6180XV0NR-1/4854909?s=N4IgTCBcDaIGoBkBsBGAHABgBogLoF8g), the VL53L0X (https://www.digikey.com/en/products/detail/stmicroelectronics/VL53L0CXV0DH-1/6023691?s=N4IgTCBcDaIG4BsCsBmBAGAxgDxAXQF8g) and VL53L1X (https://www.digikey.com/en/products/detail/stmicroelectronics/VL53L1CXV0FY-1/8258055?s=N4IgTCBcDaIGoBkCsBmBBGAwgDRAXQF8g), these sensors increase the range, speed, accuracy with each generation. Each sensor works the same way: they have a tiny near-IR laser that emits light and is bounced off nearby objects to determine the distance. The sensor has extra-ordinary time sensing, so it can measure the ‘time of flight’ between the photon emitted by the laser, and when it arrives bounced back. Thus, they are called “Time of Flight / ToF” sensors and the series of boards are called ST FlightSense (https://www.digikey.com/en/products/filter/optical-sensors-distance-measuring/542?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANohxwDsATBALqEAOALlCCAC%2BwoA). STMicroelectronics' VL53L5CX is a state of the art, time-of-flight (ToF), laser-ranging sensor enhancing the ST FlightSense product family. Housed in a miniature reflowable package, it integrates a single-photon avalanche diode (SPAD) array, physical infrared filters, and diffractive optical elements (DOE) to achieve the best-ranging performance in various ambient lighting conditions with a range of cover glass materials. The use of a DOE above the vertical cavity surface-emitting laser (VCSEL) allows a square FoV to be projected onto the scene. The reflection of this light is focused by the receiver lens onto a SPAD array.
Unlike conventional IR sensors, the VL53L5CX uses ST's latest generation, direct ToF technology, which allows absolute distance measurement whatever the target color and reflectance. It provides accurate ranging up to 400 cm and can work at fast speeds (60 Hz), which makes it the fastest, multizone, miniature ToF sensor currently on the market...the VL53L5CX is able to detect different objects within the FoV with a distance information range up to 60 cm. The Histogram also provides immunity to cover glass crosstalk beyond 60 cm. Multizone distance measurements are possible up to 8x8 zones with a wide 61° diagonal FoV that can be reduced by software.
The big updates in the L5 version is a new diffraction element which allows the SPAD to measure an 8x8 zone of distance measurements, which makes it more like a spatial LIDAR than a point-LIDAR. It's not super-fast, but you can use it for gesture recognition and possibly simple robotics-navigation. The price is not much different than before, and you still get 4 meter range. Another nice thing about this sensor is ST is starting to release 'platform agnostic' sensor drivers, including an 'ultra lite driver' for this chip that is easy to port to other platforms (https://www.st.com/en/imaging-and-photonics-solutions/vl53l5cx.html#tools-software) without heavy IDE/toolchain/chipset dependencies.
The ST VL53L5CX is in stock right now for immediate shipment from Digi-Key! (https://www.digikey.com/short/hwb7rd0m) There's also eval/dev boards if you want to get started instantly. Order today and you can add a micro-LiDAR to your project or product by tomorrow afternoon.

Our OV5640 camera is working great, but we notice it does heat up quite a bit. We want to add a little heatsink option to our breakout so that the camera can be cooled off a little while it's running. Digi-Key stocks hundreds of thousands of different heat sinks, let's see what we can find that is small enough to fit.

Last week we took a look at an OV5640 camera sample that had a voice-coil auto focus motor inside. At the time we didn't get it working, turns out the breakout we were using had some shorted connection to the VM pins. We happened to have a camera breakout PCB we're working on so we put one together and found that with a little wiring we could follow the app note to load a firmware file through I2C and then get I2C working. Now we can redesign our camera breakout to support every camera module type we've seen.

Last week when we got some OV5640 camera samples we noticed these modules have a built in voice coil motor for focusing. How neat! We followed the app guide to load in the autofocus firmware over I2C, and then over I2C you can request the camera to try and autofocus. It works very well, you can even hear the little click when it changes focus. We had to use a breakout board of our own design in order to power the motor coil externally.

The switches come in either SPDT or DPDT type, both momentary and latching on/off type, and with concave, flat or large flat clear tops. All of the ones available for purchase contain both red and green LEDs, so the front can be lit red, yellow or green. Note that there are 3 parallel LED inside, so you need 60mA per LED segment, (https://learn.adafruit.com/all-about-leds) but the front does illuminate nice and evenly which is something cheaper buttons struggle with.
The tops are also easily removable, so you can put a label underneath, and they're nice crystal clear, so you'll get nice even illumination with an easy-to-clean cover. These are really high quality buttons with an excellent clicky feel and a durable build, they're perfect for A/V or industrial equipment where a clean user interface is important.
All of the C&K KLS Series Illuminated Pushbuttons (https://www.digikey.com/en/product-highlight/c/ck-components/kls-series-illuminated-pushbutton) are in stock now at Digi-Key for immediate purchase and shipment. Order today (https://www.digikey.com/short/z3d42v8m) and you can be laying out your dream control-panel by tomorrow afternoon!

We just saw Colin's great video on 555 timers, who doesn't love these classic chips? You can still get them, heck they are one of the few things you CAN get! So, if you want to make a one-shot timer or a mini synth, check out Digi-Key for all your 555 timer needs. They've also greatly improved in performance since the '70s, with wider voltage range, lower quiescent current, and higher frequency outputs.

Thanks to jeplers intrepid and unyielding efforts, we now have OV5640 camera module support in CircuitPython. This is a snazzy 5 MPixel camera module which can do JPEG encoding on-chip and auto levels. It's a rather nice camera and given you can always use it at lower res like 320x240, we think this is our pick. We got a few samples from the camera manufacturer and interestingly enough, we got one version with a kinda fisheye lens (that works fine) and one version with a pinhole lens and a SECRET!

Time flies (or fugit irreparabile tempus as the cool Hellenistic teens might say) when you're enjoying this EYE ON NPI - this week we're featuring the Raltron Crystal Resonators Engineering Design Kit (https://www.digikey.com/en/product-highlight/r/raltron/crystal-resonators-engineering-design-kit), a kit of 66 different crystal oscillators in various packages, frequencies and load capacitances.
Crystals! (https://en.wikipedia.org/wiki/Crystal) They're so cool sounding, who doesn't love sparkly rocks? While we usually associate the word with gems, bedazzling, and new-age healing, crystals made of piezo-electric material (https://en.wikipedia.org/wiki/Crystal_oscillator) are great for generating precise sinusoids of a desired frequency. We need these to keep our electronics ticking away at the right frequency. And, somewhat annoyingly, each chip seems to require a totally different frequency. So you end up getting a lot of different crystals in your proto-typing bin. For example, 'timing' crystals tend to be 32.768 KHz, because if you have a 15 bit counter that keeps track of each oscillation, you'll count out one second every overflow. These crystals are super common, used in micro's for low-power or PLL-syncing, also in real-time-clocks that need to run on small coin cell batteries for years. So, 32KHz is maybe the most common value used that we've seen - this kit gives you many pages of them with different sizes.
For microcontrollers, especially ones with USB, you'll want 12 or 24 MHz (USB peripherals tend to run on 12MHz or some multiple). Other chips often need 8MHz, 16MHz, 20MHz, 24 MHz or 32MHz. Then, sometimes you get unusual frequency requirements - like for RFID/NFC that uses 13.56 MHz RF frequencies, you'll need 27.12 MHz crystal (it's 2x the RF frequency, not surprisingly!) So this crystal oscillator kit (https://www.digikey.com/short/n5pvt3f9) is quite handy with 5 pieces of each value.
Each crystal cut tape strip is in a pocket, looks like a holder for business cards or maybe baseball cards. The pocket is clear, so behind it is the identification information - what the part number is, the frequency, stability, tolerance, load capacitance, ESR, temperature and size. There's also a short URL and QR code for the datasheet from Raltron (big ups to them for getting their own URL shortener rather than leaning on a third party). Of course when you're ready to purchase for production, each part is stocked on Digi-Key as well (https://www.digikey.com/en/product-highlight/r/raltron/crystal-resonators-engineering-design-kit)
I love this kit for having so many values and options and sizes. Every workshop and lab should have one, so whenever you're designing a new chip, you can verify the crystal size and specifications immediately. Goes great with a Digi-Key resistor kit (https://www.digikey.com/en/products/filter/resistor-kits/653) or capacitor kit (https://www.digikey.com/en/products/filter/capacitor-kits/651).
These Raltron Crystal Resonators Engineering Design Kit (https://www.digikey.com/short/n5pvt3f9) books are in stock now for immediate shipment from Digi-Key, order today and you can be oscillating by tomorrow morning!

one thing thats annoying about electronics rework is how many hands are needed to hold all the tools: soldering wand, tweezers, paste syringe, hot air gun. this stand solves one annoyance: having to hold the hot air wand right over a spot to get it nice and toasty for repair. it can go high enough to work with a panavise, or low enough for the board to sit flat on the base. coming soon to the adafruit shop!

"Do you have a vendor you could recommend for the antistatic foam blocks you use for products with pre-soldered male pin headers? We’re on the hunt for one and would be happy to take any advice you all have! - Thanks!"
We got an email request this week from another maker in the community, who is making and selling hardware with pre-soldered pin headers. They were wondering where we get our antistatic foam for our pre-soldered boards. Great question for a Great Search! We'll show you the different kinds of foam and the sizes we recommend.

this may be helpful for folks using the latest attiny and atmega chips that are programmed with "synch uart" UPDI rather than "SPI" AVR-ISP: we've updated our self-contained/standalone programming library to add UPDI support!
the library is here, https://github.com/adafruit/Adafruit_AVRProg
example here: https://github.com/adafruit/Adafruit_AVRProg/tree/master/examples/attiny817_updiprog
we can erase-program-verify an 8KB flash chip in 2 seconds, super fast. great for loading firmware in production.
thanks to bradanlane's portaprog for much of the updi support implementation: https://gitlab.com/bradanlane/portaprog/-/blob/master/src/avrupdi.cpp

Last week we showed that the VL53L1X has the same shape and pinout as the VL53L0X, making it an easy addition to our collection of STEMMA QT boards. We ordered new boards with a different silkscreen and now its time to make a tester. Our sensor breakout testers follow a common process - we don't have a library or anything but we'll show how we test each element of a sensor!

This week's EYE ON NPI is a pal that fits right in your pocket, literally! It's the Pokit All-in-One Meter, (https://www.digikey.com/en/product-highlight/p/pokit-innovations/pokit-meter) a miniature wireless multimeter, scope and datalogger. We've seen designs like this become more popular lately as many folks have phones on hand, which can act as a display (the display/UI is one of the more difficult and expensive elements of portable test equipment). When this one popped up on https://www.digikey.com/new we thought it would be worth checking out as it does a good job of matching enough desired specifications to be useful to a Maker or engineer.
We like the mechanical design - it has got a cute retractable cable kit that you can pull out for use. The design of the probes is such that you can plug in optional and included micro-grabbers if desired, but the tips can be used as is. (We'll note that the micro grabbers don't fit into the body or anything so they need to be carried separately). While it's a tad large for a keychain, it isn't an outlandish size - it definitely could go into a purse or pocket without snagging. There's also a zipper pouch for those who like to keep their tools in a home.
To work with any phone, it uses BLE for data transport. Unlikely many products we see, this doesn't use a rechargeable battery. Instead, the battery is an every day CR2032 (https://www.digikey.com/en/products/detail/jauch-quartz/CR-2032-JAUCH-IB/13540138) which you can get replacements for at any hardware or corner shop. There's pros and cons to going with a primary cell, but we think this was probably a good choice as long as the battery level is well communicated to users.
The processor inside is a Silabs EFR32BR13 wireless microcontroller (https://www.digikey.com/en/products/detail/silicon-labs/EFR32BG13P732F512GM32-D/10135841) and a little bit of circuitry. Connecting is easy, after removing the battery tab, download and open the app, it will pair immediately - this went very smoothly. Then from the main screen you can select various functions. Most functions acted just the way you expect: continuity test, DC voltage measurement, temperature and resistance. There is a current measurement capability, which also means there's a fuse. You do get a spare fuse, and as most multimeters go, its something you'll probably mess up once by accidentally measuring in parallel. Thankfully the app warms you before going into current measurement mode.
There's only one thing that folks should be aware of: there is an 'oscilloscope' mode but it really is more of a 'data capture' mode - the BLE link isn't fast enough to stream data, even triggered-signal data. Arguably, it's hard to do this reliably over BLE, but I think it is possible to have some data rate streamed, even if just to make it easier to verify that the right spot is probed - and it would be a really awesome feature. I think BLE 5 with large, non-acknowledged packets could do it. (https://www.novelbits.io/bluetooth-5-speed-maximum-throughput/) But perhaps it wouldn't work reliably on every model of phone. Hopefully next revision could do it since it would be such a killer feature!
For something so small, it really does pack a good amount of capability, and while it would not replace your desktop scope or multimeter, it is a great addition to a dev kit. I could have really used something like this when traveling or at events! We picked up the transparent one because we are suckers for clear plastic, but there are a few different colors of the Pokit All-in-One Meter, all of which are available in stock at Digi-Key right now for immediate shipment (https://www.digikey.com/en/product-highlight/p/pokit-innovations/pokit-meter). Order today and you'll be toting this lil keychain toolkit with you tomorrow afternoon!

1980 was a different world. Things we now take for granted, like doing math on a computer — A MACHINE DESIGNED TO DO MATH — were often impractical. You might’ve kept a calculator alongside your computer so you could math while you math.

We're working on adding support for the I2C protocol to Adafruit.io WipperSnapper so people can use WipperSnapper to send data from their favorite I2C sensors to the internet, without writing a single line of code.
We wanted to show off the first step, which is scanning for connected I2C devices over the I2C bus (over WiFi!). This test is going to be kept when we launch WipperSnapper, so people can easily query which sensors are plugged into their board.
What is WipperSnapper? Wippersnapper is Adafruit's no-code IoT interface for Adafruit.IO – it lets you turn any WiFi-capable board into an IoT device without any programming. Get started with WipperSnapper by visiting http://io.adafruit.com/wippersnapper

Sadly, today we learned that the ADXL377 (https://www.adafruit.com/product/1413) is no longer going to be made due to the process being retired. Let's try to find a replacement!

One of the things we've tried to do lately is 'unify' all our breakout boards and sensors to STEMMA QT so that we have the same shape and size for boards (which makes them mechanically easier to swap). Sometimes we get super lucky and we can even get devices that are mechanically swappable. For example, the BME280/BMP280/DPS310 environmental sensors all share the same pinout. We also remembered our old friend the VL53L1X which shares the same pinout with the VL53L0X, which we got working this week thanks to ST's library. Finally, Analog Devices has thankfully settled on a pinout for their accelerometers, so we QTified it too!

This week's EYE ON NPI is "ne-plus-ultra" (that's French for best-of-the-best) because we're featuring Broadcom's Ultra Violet SMT LEDs. (https://www.digikey.com/en/product-highlight/b/broadcom-semi/3w-3535-surface-mount-uv-leds) UV LEDs had their 'day in the sun' this year, due to being used by many companies to perform UV surface sterilization, but they're really useful for many scientific purposes and its great to see these LEDs make it into a binned, surface mount, high current package.
UV LEDs, are as you can expect, are LEDs that emit light in the UV band, which ranges from 10 to 400nm. (https://en.wikipedia.org/wiki/Ultraviolet) Note that visible light is 400~700nm (https://en.wikipedia.org/wiki/Light) so the range of the UV band is quite wide. UV light is 'higher power' than visible light - it's what is emitted from the sun that gives us sun burns, it is also mutagenic - so wear that sunscreen! Because there isn't a lot of it on Earth, but it can affect chemical bonds, it's very useful for when we want to control a chemical reaction such as UV curing or disinfection or bleaching, with pinpoint control.
For example, 3D resin printers use UV lenses or lasers to selectively cure layers of a print with high precision - called stereolithography (https://en.wikipedia.org/wiki/Stereolithography). It's also very popular in dentistry where hard composite resins are UV-cured quickly and safely (https://en.wikipedia.org/wiki/Dental_curing_light).
We first started using UV lamps when doing in-house PCB etching at school - at the time we used a 15W UV fluorescent bulb (https://www.ladyada.net/library/pcb/inhouseetch.html) If you like getting your nails done with a strong and durable polish, you're probably familiar with using a UV lamp to cure a gel manicure in a minute or two (https://learn.adafruit.com/uv-manicure-lamp) and most recently we found that clear UV resins are great for making custom MX keycaps for mechanical keyboards (https://learn.adafruit.com/diy-decorative-resin-keycaps)
Now, historically, folks have used UV fluorescent bulbs (https://www.digikey.com/en/products/filter/lamps-cold-cathode-fluorescent-ccfl-uv/104) for getting UV light, but these are becoming less common in many use cases because UV CCFLs are cheap, but are delicate (made of glass), are physically large and hard to focus on a small area, dim over time, are hard to dispose of (they often contain mercury or other metals), require a complex ballast/driver, and can take a while to warm up. In contrast, UV LEDs are a great alternative with better precision, long life, and easy driving.
These UV LEDs from Broadcom are 'true' UV LEDs (https://www.broadcom.com/products/leds-and-displays/ultraviolet-leds), and come binned for three different center frequencies: 365nm, 385nm and 395nm. When buying low cost LEDs, they often have some variation which can reduce efficiency in the desired band. And of course, the band has to be aligned with whatever you're curing or disinfecting. These would do the job admirably whenever you want a durable, long-lasting UV source with exactly the right emission spectrum, particularly when small space and high efficiency such as a battery-operated device is concerned.
And best of all, the Broadcom 3W 3535 Surface-Mount UV LEDs are in stock and ready to ship right now from Digi-Key (https://www.digikey.com/en/products/detail/broadcom-limited/AUV3-SQ32-0RT0K/13693503). Purchase a cut tape strip or Digi-Reel for instant shipping, order today and your curing quest can be 'cured' by tomorrow morning.

Our HT16K33-based LED backpacks are a classic Adafruit design we've sold for many many years. So we're thinking of updating them to QT-fication for easy plug-n-play usage. We're going to do the 7-segment and quad-alphanum at the same time. maybe also a mini 16x8 too.

On yet another stemma sunday, we're revising our ancient HT16K33 LED backpacks to include QT connectors - we're also going to try to 'unify' two or three of the layouts so they can share the same PCBs. We're also interested in redoing some of our microphone breakouts so they're easier to use in a classic stemma breakout shape. We put together both electret and MEMS versions

This week's EYE ON NPI is from our best buds at Bud Industries - the Bud AIO Series Enclosure with Cover Window (https://www.digikey.com/en/product-highlight/b/bud-industries/aio-series-enclosure) is a very nice case that is a step above most durable wall-mounted enclosures.
In particular, what is really nice about this design is there are two 'doors' - one is the main enclosure latching door that lets you stuff a whole bunch of electronics inside. There's also a secondary clear panel door on the front, which is also latching (although not with metal hasps). Both are gasketed for weatherproof-ness. Obviously, the front door is designed for showing TFTs, LEDs, gauges or other indicators with a protected cover. However, we like the extra step of being able to open the cover to push buttons, tweak knobs or maybe interact with a touch screen without opening up the whole box which could expose the electronic design to dust or dampness.
Bud's great with their documentation (https://www.budind.com/wp-content/uploads/2020/12/hbaio11111.pdf) - and the two AIO series enclosures come with datasheets that have nice diagrams of all internal and external dimensions in inches and millimeters. There's lots of mounting holes/bosses on the inside for attaching a PCB or substrate - the holes are threaded and the enclosure comes with plenty of mounting screws.
The enclosure is made of ABS plastic, which makes it very easy to drill and cut. (https://www.google.com/search?channel=nus5&client=firefox-b-1-d&q=abs+plastic+machining) There's a removable plate that sits between the inner and outer section, which means it's easy to remove for machining. If you need a lot of custom panels, it may also be possible to just cut out plastic/metal/wood on a router with the drill holes and slots you need. There's also internal panels you can purchase that fit inside the case with lots of holes for quick mounting (https://www.digikey.com/en/products/detail/bud-industries/PTX-10140/13907429)
Another nice detail we noticed in our exploration is the gasket material is extruded and molded to the enclosure, rather than a simple o-ring or rubber bead. That's what gives it the nice IP66 rating (https://en.wikipedia.org/wiki/IP_Code) for dust-proof and waterjet-proofness. That said, because it's non-stabilized ABS, it isn't well suited for any long-term outdoor mounting as it can degrade under sunlight. It could be used outdoors as long as it isn't exposed to sunlight too much, but it's really designed for durable indoor use.
IP66-rated enclosures are dust-tight and provide a strong level of indoor-outdoor protection. Boxes that qualify for this rating will prevent ingress of water directed at high pressure. Typically IP66 waterproof enclosures are used in washdown and outdoor applications, such as factories, rooftops, solar installations, and agricultural settings. They give maximum protection against pressure-washing and weather short of water immersion. https://www.budind.com/nema-ip-rated-boxes-ip-66
There's two versions of this enclosure with different depths: the Bud AIO-11111 (https://www.digikey.com/en/products/detail/bud-industries/AIO-11111/13907415) and the Bud AIO-11112 (https://www.digikey.com/en/products/detail/bud-industries/AIO-11112/13907416), the '11111 is 9.5" deep, the '11112 is 7.7" deep. Both are in stock right now for immediate shipment from Digi-Key! (https://www.digikey.com/short/4zznn9h3)
Order today and you can have a cozy enclosure for your product or project by tomorrow morning.

A die-hard interface chip that is the backbone of many-a-devboard is the USB-to-UART adapter chip. While many micros come with native USB, there is still a large number that have UART only - like the ESP32, or RISC-V cores.
Since most computers don't have a UART/RS232 port anymore, we're often converting UART to USB. For many years, we really like the CP2104 for low-cost and consistent/reliable behavior. That's NRND now, so what shall we find to replace it?

This week's EYE ON NPI is going to keep you safe and sound, it's onsemi's portfolio of eFuses (https://www.digikey.com/en/product-highlight/o/on-semi/efuse-porfolio) - chips that can perform many of the protective functions we build into our power supplies to keep devices from going poof when accidents occur!
onsemi has developed a wide range of eFuses ranging from 3 V to 12 V, supporting a continuous current from 1 A to 12 A. The integrated overcurrent, overtemperature, overvoltage, and inrush current protection, along with the ability to report faults and disable the output through GPIO, make these devices suitable for protecting any system, helping meet the challenges and supporting a compact board layout.
When people first meet fuses, they usually see and think of classic 'wire' fuses (https://www.digikey.com/en/products/detail/bel-fuse-inc/5ST-200-R/1009012) with ceramic or glass or thermoplastic bodies, and a thin wire inside. When too much current goes through the fuse wire, it gets hotter and hotter and eventually melts, cutting off the load from the source voltage. Pros: super cheap, easy to find, lots of suppliers with various current limits Cons: only good for overcurrent, one-shot usage only!
Once engineers start making products, they often want to include fuses to protect their circuitry: over-current usually means something is getting damaged and we want to keep away from thermal damage like charring or even a fire. Many traditional/older designs use glass fuses, like appliances, radios, kitchen tools...but a lot of engineers prefer going with 'poly fuses' - fuses that are easy to mount into a circuit that auto-reset after a time (usually minutes) so that a temporary overload doesn't make the device a brick so quickly. For example, we have a 500mA hold / 1000mA trip polyfuse (https://www.digikey.com/en/products/detail/bel-fuse-inc/0ZCJ0050FF2G/4156133) on the Metro 328 board design (https://www.adafruit.com/product/2488), usually it kicks in when people try to power 4 servos off of the USB port, quickly overwhelming the computer or hub. Poly-fuses are a great step-up from plain wire fuses. Pros: also cheap! lots of suppliers with various current limits. auto-resets after cooling down. Cons: only good for over-current, can't latch off, fuse trip time depends on ambient temperature
But circuit protection usually needs more than just over-current checks. We often have to do polarity protection (in case the battery or wall adapter is put in backwards), and over-voltage (to avoid damaging the regulator, which will have some voltage limitation) and under-voltage (to avoid weird or inconsistent behavior during a brown-out). There's also some products that benefit from 'latch off' behavior - where a failure means we have to do a hard power cycle. What if we could do all this in one chip? No surprise, that's what we're showing off this week!
The NIS5420 eFuse is a cost effective, resettable fuse which can greatly enhance the reliability of a hard drive or other circuit from both catastrophic and shutdown failures. It is designed to buffer the load device from excessive input voltage which can damage sensitive circuits. It also includes an overvoltage clamp circuit that limits the output voltage during transients but does not shut the unit down, thereby allowing the load circuit to continue operation.
Integrated Power Device Power Device Thermally Protected No External Current Shunt Required 8 V to 18 V Input Range 39 mOhm Typical Internal Charge Pump Internal Undervoltage Lockout Circuit Internal Overvoltage Clamp
These chips do it all. Obviously they've got the current limiting setup, but they also have under-voltage locking, over-voltage clamping for short bursts of high voltage, slew rate control, enable / fault pin, and optional external current monitoring. It's all analog electronics so it works instantly, reliably and without digital configuration. Stuff like the current limit and slew rate is set with external passive components. It looks like these were designed for use in hard drives, which means they are good in stressful environments like server racks, data centers or home computers. We always love chips that do something and do it real well, at a good price. These eFuses will replace a chunk of your power-supply protection kit, saving your assembly cost and board size.
While we're specifically featuring the onsemi NIS5420 (https://www.digikey.com/short/nt2zhct2) here, there's a whole family of different voltage-set chips to pick from (https://www.digikey.com/en/product-highlight/o/on-semi/efuse-porfolio) for 3V, 5V, 12V or even 24V power rails. And best of all, they're in stock right now for immediate shipping from Digi-Key! Order now and you can start designing into your product line tomorrow morning.

OK we're about ready to fabricate these LED glasses panels. Lots of LEDs, in a cool grid/circular design! Of course, we have to test each board so that we know all the LEDs were placed properly. Thus, the tester! We're going with a simple R/G/B test, with visual inspection.
We'll also check out the built in test-mode the IS31FL3741 has, so we verify all the RGBs two ways. Check out the fancy silkscreen, we'll have these in the shop sooooooon.

We use the AON7401 in a LOT of our designs, it's a high-current power P-FET that we use for polarity-verification / voltage-switching. For example, in our RGB Matrix FeatherWing, it's used to make sure we have a positive voltage going from the DC jack to the RGB Matrix. Sadly this exact part is discontinued. Let's try to find a drop-in replacement with as-good-or-better specifications!

We're always looking for more I2C-friendly displays to add to our line-up. This is a 128x128 monochrome OLED breakout we just put together, with SH1107 driver. It's a smol 1.12" inches and has both I2C and SPI interfaces. Use I2C when you want quick wiring, use SPI when you want fast speed. Either way, its crisp & clear and we'll have Arduino & Python code. Coming soooooon!

This week's EYE ON NPI is caring and sensitive... Conductive Containers' Corstat® (https://www.digikey.com/en/product-highlight/c/conductive-containers/conductive-pcb-mailers) and PillowStat (https://www.digikey.com/en/product-highlight/c/conductive-containers/pillowstat-injection-molded-component-cases) mailers are soft and ESD-safe, so they will never break your heart or give your delicate electronics a nasty shock! After manufacturing, you'll need to get your boards to a final manufacturing or packaging facility. Or, your boards may be sold 'bare' to the end user. That's where these mailers come in to save the day: they are durable, and fully ESD-safe with coated cardboard and foam. We've seen chips and displays arrive to us in Corstat mailers, but it somehow never crossed our minds that we could buy them off the shelf!
Conductive Containers (https://www.digikey.com/en/supplier-centers/conductive-containers) are experts at ESD things of all shapes, sizes and extrusions. We're doing a 2-for-1 on this EYE ON NPI, highlighting both their 'convoluted pink foam' (https://www.digikey.com/en/product-highlight/c/conductive-containers/conductive-pcb-mailers) and 'flat black folding-mailers' (https://www.digikey.com/en/product-highlight/c/conductive-containers/pillowstat-injection-molded-component-cases) If you have special packaging needs, you can always contact CCI for custom sizing, but their 'off the shelf' packages come in a range of sizes and you can get them instantly in almost any quantity, thanks to their fabrication facilities in the US (CCI also makes all sorts of other ESD handling/storage items which we use here at Adafruit for holding reels and components.)
We like that these boxes in that you don't have to antistat, bubble bag and separately box: it's an all-in-one step. And the boxes ship nice and flat, with good creases, so they're very fast to assemble. Digi-Key carries a wide size range of both Corstat® and PillowStat mailers (https://www.digikey.com/en/supplier-centers/conductive-containers) so full PCB assemblies and individual components can be packaged safely. Order any Conductive Containers from stock (https://www.digikey.com/short/vwpz3ht7) today and you can have packaging problems solved by tomorrow afternoon!

The Paper Shoot camera we did an unboxing of has a nifty SP4T slide switch. Slide switches are one of our favorite interface elements: they've intuitive for anyone and don't get reset by a power loss. Lets look at how we can find various slide switches, and how to identify what kind of switch we've got by symbol.

We sat down today to do the mapping for our LED glasses which have both rings and a planar matrix. Mapping LEDs or pixels is one of those time-worn tasks that we often end up grinding through - we'll chat about how we made it go fast!
Also, an unboxing of a Paper Shoot camera, these are low cost 'DIY' cameras that come with a bare PCB and a foldable case. There's 4 filters you can apply to the camera output and there's no TFT - just a cutout viewfinder. Let's take a look at what we can find on the PCB itself
The Great Search - SP4T Slide Switch https://www.digikey.com/short/f2p4hwjb
The Paper Shoot camera we did an unboxing of has a nifty SP4T slide switch. Slide switches are one of our favorite interface elements: they've intuitive for anyone and don't get reset by a power loss. Lets look at how we can find various slide switches, and how to identify what kind of switch we've got by symbol

This week's EYE ON NPI is ready to be part of your tag-team crew: it's ST's ST25DV-I2C-EVO Dynamic NFC/RFID Tags IC (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/st25dv-i2c-evo-dynamic-nfc-rfid-tags-ic), available in a few different memory sizes. We're psyched to get to feature this chip on EYE ON NPI because we found an earlier version of these chips -- the ST25DV16K (https://www.digikey.com/en/products/detail/stmicroelectronics/ST25DV16K-IER6T3/6691420) -- a few months ago and made a STEMMA QT breakout for it (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4701/13688447).
Even though at the time we sorta thought this would be a niche product it turns out it's quite popular thanks to the straight-forward simplicity
Basically, this chip is a 'smart' RFID/NFC tag. Normally, when you think of an NFC tag, you'd picture one of these RFID cards (https://www.adafruit.com/product/4034) or stickers (https://www.adafruit.com/product/4032). These are small chips that have built in memory that can be read or written when self-powered by an RFID field. One of the neat things is that they are electronic devices that do not get powered by a battery. Don't get us wrong, we really like batteries but they are real pain to manage - you have to manage sleep stages, recharging, under/over voltage, chemical leaks, etc. Low power management is really hard.
The nifty thing about RF-powered electronics is how many problems they 'solve': by default they draw no power, so you don't have to worry about sleep modes. There's no battery, so no recharging or replacement needed. They only turn on when physically close to the reader, and auto-turn-off when the reader is away - the UX is intuitive and does not require any buttons.
Most tags and cards address a static chunk of memory, maybe a few K in size. You touch to write/read or authenticate. They're super cheap, easy to embed in every credit card. However, they often don't do anything other than the read/write/auth behaviors - it isn't possible to expand the capabilities since there's only a couple different chips. That's where the ST25DV series (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/st25dv-i2c-evo-dynamic-nfc-rfid-tags-ic) comes in!
The ST25 series looks just like an ISO 15693 tag (https://en.wikipedia.org/wiki/ISO/IEC_15693) to a reader, but there's also an I2C interface that can be used to easily change the memory contents. This means its a fast and mobile-friendly way to transmit data back and forth without a massive amount of development to handle the data encapsulation. Both Android and iOS have built in NFC support for this tag format and you can easily query/write data via the NFC API. ISO 15693 has a specification of up to 1 meter (when used with a large-antenna RFID reader), a few inches from a phone. For the antenna design, ST has a nice eDesignSuite website that will do all the math for you, to create an antenna tuned to the size you have available (https://www.st.com/content/st_com/en/support/resources/edesign.html)
Even if your product does have a battery, say for a datalogging system, using NFC for data transfer will use a lot less power than BLE or WiFi - and without the mess of differentiating many nearby devices, BLE pairing, or wireless/cellular credentials & deployment. And usage is super simple - we were grateful to see an Arduino library written by ST with an instant gratification example (https://github.com/stm32duino/ST25DV). Thanks to I2C's universality, the code can be ported to any microcontroller.
If your microcontroller is a low-power device, you may be able to use the energy harvesting output from the ST25 chip to power your circuitry. Depending on the EM field strength, you can get up to about 3V at 1mA or 7mA at 2.3V (https://docplayer.net/169359266-Nfc-rfid-st25-product-overview.html)
You can order these in a few different SMT packages and sizes from Digi-Key - the SOIC and TSSOP packages are available now with 4Kbit, 16Kbit and 64Kbit memory size. (https://www.digikey.com/en/products/filter/rfid-rf-access-monitoring-ics/880?s=N4IgTCBcDaIMoBUwFYAiA1EBdAvkA)
The new KC series seems to add the ability to change the I2C address, but if you don't need that, the plain K series is pin compatible as well. We recommend starting with the SOIC version of the ST25DV16KC (https://www.digikey.com/short/jt4h3rrh) for an easy-to-solder starter chip. It's in stock and ready to ship immediately from Digi-Key - order today and you can be NFC'ing by tomorrow afternoon!

Yay our IS31FL3741 PCB is finally fabbed - we made some with two different LEDs to compare. Thankfully our yield was 100% for the 4 panels we manufactured. Next up we're going to test out and bring up our LED glasses design which is basically a mechanically 'deconstructed' version of the same board. Most annoying part? Doing the LED mapping! We actually found its easier to do that in CircuitPython first since we need to do very fast iteration.
Special Request! Booster/DC-DC Switching Regulators with Low Quiescent Current https://www.digikey.com/short/r58fw35v
This request came in on YouTube - someone looking for a low quiescent current boost regulator. This is a pretty common thing to look for, but its actually not easy to search for! Also, DC/DC regulators are hard-hit by the silicon shortage & we want to find one in stock. Tune in to find out some suggestions and how I found a good option to explore!

When you start putting a ton of RGB LEDs on a board, the price of 'smart' pixel LEDs like NeoPixels & DotStars starts to add up. That's why we fancy this IS31FL3741 breakout, which has 117 RGB common-anode LEDs, each one controlled with 8-bit-per-channel PWM. At a penny or two per, we can sell this board for a reasonable price and its fully controllable over I2C.

This week's EYE ON NPI is moving in the right direction - it's U-Blox's XPLR-AOA Direction Finding and Indoor Positioning Explorer Kit! This NPI tries to solve a well-trod but still not-fully-solved technical challenge of how to perform 3D tracking of low cost/low power 'tags' indoors. Ironically, object tracking is something that humans and animals do very well - we can even track things that have hidden themselves from view! But for robotics, this is an incredibly hard problem.
Let's talk about some of the ways that we can do object tracking now, to explain why something that sounds so simple has been a challenge for decades. The way robotics do object tracking now is how the most simplistic organic vision systems work: by looking for a contrasting color or shape. This works best if something is vividly colored - like an Aibo robotic dog tracking a round pink ball (https://commons.wikimedia.org/wiki/File:AIBO_ERS-7_following_pink_ball_held_by_child.jpg#filelinks). Works great if the thing you're trying to track happens to be round and pink, which is not many things on this planet. Also, doesn't work particularly well if the shape is hidden or obscured.
The next step up from basic shape tracking is machine learning vision systems that try to recognize objects by using layers of matrix calculations - what we would normally call OpenCV (https://en.wikipedia.org/wiki/OpenCV) or TensorFlow (https://en.wikipedia.org/wiki/Object_detection#/media/File:Detected-with-YOLO--Schreibtisch-mit-Objekten.jpg). This is a little more flexible, but still requires good lighting, unobscured vision, and recognizable shapes.
If you don't want to use a camera, and you happen to be outside, you can use GNSS/GPS. A board with a GPS module and a radio transceiver can pretty easily determine location and then relay it back to a central station. GNSS gives you up to 10 meters This is great for cars, people, boats - all sorts of large objects. But that 10 meter precisions makes it tough for smaller items and of course, GNSS does not work indoors. (If you do want better precision, you can get it using RTK - check out our EYE ON NPI from last year https://blog.adafruit.com/2020/06/08/eye-on-npi-u-blox-c099-f9p-application-board-for-zed-f9p-gnss-rtk-module-eyeonnpi-adafruit-digikey-digikey-ublox/)
Traditionally, when working indoors to do tracking, folks have relied on a few different technologies. In particular RSSI tracking is quite popular because its so cheap. Basically, radio signal strength falls geometrically with distance from antenna to antenna.
Folks can also use time-of-flight technology, which has slowly been making it to WiFi modules (and may also make it into BTLE at some point - we'll do EYE ON NPI on that technology when it filters into the market!)
As of Bluetooth 5.1, there's a new Direction Finding capability built into the wireless specification.
Bluetooth direction finding makes it possible to determine the direction that radio signals travel from a mobile tag to one or several fixed anchor points. Using angle-of-arrival (AoA) technology, anchor points comprising an antenna array that is connected to a Bluetooth receiver can detect the direction, or angle, to the mobile tag, which transmits a Bluetooth signal. When a constellation of such multi-antenna anchors is deployed, AoA technology can be used to triangulate the precise location of a mobile device or tag. (https://www.u-blox.com/en/press-releases/u-blox-presents-bluetooth-aoa-explorer-kits-high-precision-indoor-positioning)
Note that this is not distance measurements, it's angular measurements. But, of course - if you have a few fixed antenna station locations its easy to convert a set of angles into a precise location! The angle calculations seem to give better accuracy than plain RSSI - 1 to 2 meters - and can be used for more than just location sensing. For example, in this demo from U-Blox, a camera can follow a tag just with angular data since we don't care how far away the target is, just that it is in frame (https://www.u-blox.com/en/blogs/tech/how-we-built-our-bluetooth-direction-finding-demo)
Direction Finding is included in any U-Blox/Nordic module that supports BLE 5.1, but to make it easy we recommend picking up a XPLR-AOA Direction Finding and Indoor Positioning Explorer Kit (https://www.digikey.com/short/q3dpn32p) that has the antenna configuration needed and laid out. It's a lot easier and faster than routing your own boards - the 'tags' are any BLE module and do not need special design considerations.
Lucky for us, the U-Blox XPLR-AOA Direction Finding and Indoor Positioning Explorer Kit (https://www.digikey.com/short/q3dpn32p) is in stock at Digi-Key right now, and is an excellent way to get started immediately with trying out the new technology. If you want a more advanced setup, with 4 fixed-point-nodes and 4 tags, sign up for the XLPR-AOA-2 kit (https://www.digikey.com/en/products/detail/u-blox/XPLR-AOA-2/14666759).

We just got an update notice of a crowdfunding campaign that is struggling with how to find an alternative for their specified regulator, the TI TPS73101. We thought we'd take a look at what alternatives we could find - in case other folks are having regulator-sourcing issues! (This part may not actually be a drop in alternative for this project, we're just using it as inspiration!)

We just posted about a clip from a new movie out this month called "The Suicide Squad" which, for like a tenth of a second, has an Adafruit breakout board visible as part of an explosive prop. What's funny is how when we streamed this I noticed the board immediately. What makes an Adafruit board so adafruity? We'll cover our style and why we do it that way. The Great Search - TPS73101 Ultra-Low Dropout Adjustable Regulator Alternative https://www.digikey.com/short/28j2b28d
We just got an update notice of a crowdfunding campaign that is struggling with how to find an alternative for their specified regulator, the TI TPS73101. We thought we'd take a look at what alternatives we could find - in case other folks are having regulator-sourcing issues! (This part may not actually be a drop in alternative for this project, we're just using it as inspiration!)

0:00 Getting Started and Hellos 5:03 Housekeeping 7:52 What is the status of strategy / plan fir an RTOS or real-time executive? 13:20 what was the first computer language that you learned and what is your all time favorite? 16:31 What are for arguments for switching to circuitpython vs the usual arduino IDE ? 20:27 how many circuit python boards has ever adafruit made? 22:16: how do we as hobbyist debug CP? Other than a bunch of print statements. 24:57 how about that steroids game? 29:15 Actually that prompts a question--are you a developer that needs new challenges constantly? Does that drive the new projects, like the balance board? 37:38 What was the biggest change in 7.0.0? 44:08 speaking of status LED. I noticed the PyPortal, MatrixPortal, and esp32spi_wifimanager have a neopixel status LED for wifi. Curious why the wifi shared-bindings library doesn't do status led. 55:56 This is always interesting to hear a dev explain... What do you typically look for when doing a PR review … 1:01:53 is there any performance to be gained from having many instructions on one line opposed to spreading things out vertically, which most seem to do? 1:05:41 I worked a place that had a really in depth review process and you could spend the time to understand it not only to review the code but so everyone was familiar with the whole system. 1:11:06 oh circuitpython is compiled and not just interpreted ? 1:13:56 Where do hardware drivers (written in C) fit in (like keymap) 1:16:36 Made sense... Thanks. Is it possible to add your own C code drivers? 1:25:55 How do the core devs for circuit python divide up the work/of knowledge base of the core. How do you dive in and learn more/refer to someone else when it's not a problem you're familiar/experienced with, etc? 1:30:53 Other than the saleae, what tools do you use to help during this? 1:54:51 Any recommend arduino compatible RISC-V MCU board? 2:02:25 wrap-up

This week's EYE ON NPI is a great new tool in your data-acquisition toolkit, the new MAX22530 family of isolated ADCs (https://www.digikey.com/en/product-highlight/m/maxim-integrated/max22530-self-powered-4ch-isolated-12bit-adc-maxsafe)
Maxim’s MAX22530 self-powered isolated analog-to-digital converters (ADCs) are galvanically isolated, 4-channel, multiplexed, 12-bit ADCs in the MAXSafe family product line. An integrated, isolated DC/DC converter powers all field-side circuitry, enabling field-side diagnostics even when no input signal is present.
It's pretty common to have a built in multiplexed ADC in microcontrollers these days - to the extent that usually folks only wire up an external ADC when there's some particular capability they need - high accuracy, wide range, programmable-gain, etc. This ADC has a lot of great specs going for it - 4 channel so you can monitor a few different points or take some differential measurements if needed, 12-bit is a nice balance that gives good precision (4096 points, which on a 5V measurement scale is about 1.2mV, and 20 kSPS over SPI for easy integration and up to 10KHz signal bandwidth.
Most importantly, it's got full 5kVRMS isolation between the measurement side and the ADC/logic side (the ADC is on the isolated side). And not only is the digital side isolated but you also get a isolated DC/DC which powers the ADC half - it's only up to 5V and it's only 10mA or so, so it's not for power, just for reference. Still, that means you can tie the 'field' half whatever ground you like and take your measurements without worrying about connecting the power supplies together.
There's also some nice extras for higher-reliability practices. Most ADCs are simple clock-in-data-out devices, but this one has error checks for common mistakes that can occur when doing data capture in electrically-noisy environments:
Diagnostic and Fault Reporting Features: The MAX22530–MAX22532 continuously monitor multiple possible fault conditions, and a hardware alert is provided through the open drain pin, which asserts low when an enabled fault is detected. The possible faults are: ADC functionality error, SPI framing error, CRC errors from SPI communications, and loss of internal isolated data stream.
This makes the MAX22530 (https://www.digikey.com/short/1q7zpfrr) a super-easy-and-reliable to use ADC for any data acquisition when you are monitoring power systems that may have non-earth-ground references, high side voltage measurements that are out-of-range for a regular ADC's common modes, or when there's a lot of digital noise that you want to make sure doesn't get coupled in. We love these simple and effective parts - they do one thing well, and don't need special treatment to get the job done.
And best of all, the MAX22530 (https://www.digikey.com/short/1q7zpfrr) is in stock right now at Digi-Key for immediate shipment. There's an eval board we picked up as well, (https://www.digikey.com/en/products/detail/maxim-integrated/MAX22530EVKIT-/14115472) which comes with an FT2232 USB-to-SPI interface and Windows software for quick testing to verify it will function in the environment you're working in. Book today and you can be taking fully-isolated ADC measurements by tomorrow morning!
See on Digi-Key at https://www.digikey.com/short/1q7zpfrr

This week's EYE ON NPI is ready to be tested - it's a super powerful piece of test equipment from Digilent - we are happy to feature the Digilent Analog Discovery Pro 3000 Series (https://www.digikey.com/en/product-highlight/d/digilent/analog-discovery-pro-3000-series).
The Analog Discovery Pro 3000 (which we will shorten to ADP3000) is a huge upgrade from the EYE ON NPI we had last year with Digilent's Digital Discovery pod (https://blog.adafruit.com/2020/09/03/eye-on-npi-digilent-digital-discovery-eyeonnpi-digikey-digikey-digilentinc-adafruit/). That product was a small digital logic analyzer, great for doing firmware debugging with up to 32 channels of 200 MS/s data capture and lots of built-in bus decoding. To match with the Digital Discovery, Digilent also came out with the Analog Discovery 2 (https://www.adafruit.com/product/4652) with two analog input channels of 14-bit, 100MS/s, 30MHz ADC and 16-channel logic analyzer.
The Analog Discovery 2 is a great student/maker/beginner mixed-signal tool, and compact enough that you can fit it into your laptop bag for analysis anywhere. But if you want something that is comparable to a 'real' scope, you'll find that you'll want something that can take real scope probes and BNC output for those high speed signal generations. That's why there's now the ADP3000 (https://www.digikey.com/en/product-highlight/d/digilent/analog-discovery-pro-3000-series) - the 3000 means its 1500x 'more extra' than the Analog Discovery 2? Which gives benchtop-ruggedness to a digital USB scope.
The ADP3000 series is a 'little bit of everything': Two or four analog inputs with 100MS/s sample rate, 50 MHz bandwidth, 14-bit, +-25V input 16-channel logic analyzer and waveform pattern generator, 1.8 to 5V input, 125 MS/s sample rate Two analog waveform outputs, +-5V, 14-bit, 15MHz bandwidth
Now, to be completely fair - this isn't going to replace a benchtop scope. Even my trusty old Tek TDS2014 (https://www.tek.com/oscilloscope/tds2000-digital-storage-oscilloscope), bought 15 years ago, has 1 GS/s and 100 MHz sample rate. And, personally, I still really like twiddling physical knobs when debugging a circuit. So we think that while it could be used as a benchtop toolkit, the ADP3000 isn't designed for that.
Instead where we think this tool would really shine is automation or test engineering, where components or setups need to be analyzed or as part of a integration test. That's because Digilent is a wholly-owned subsidiary of National Instruments (https://www.ni.com) who make LabVIEW (https://www.ni.com/en-us/shop/labview.html) an extremely-popular lab/data capture/analysis program. So you know that there's going to be excellent integration, with the Digilent tools getting "First Class" support in LabVIEW. Having seen physicists/biologists/mech e's struggle with how to automate their experiments, this tool would work very nicely in a graduate or company lab.
One feature that really stands out for the ADP3000 is that, yes, you can plug it into a computer via USB like you'd expect to capture data on a host PCB, but you can also log in directly into the scope in "Linux Mode". (https://reference.digilentinc.com/test-and-measurement/analog-discovery-pro-3x50/linux-mode) Not surprisingly, this scope runs embedded Linux, that's how it can do stuff like have USB host and Ethernet. But even with Ethernet, there's always the risk of bandwidth or dropped packets. What if you want to get some large data capture going, where you don't want to be restricted by USB? Or if you wanted to connect some additional hardware? We like that Digilent opened up this capability - most test equipment companies would not be excited to let the user log into the device itself and mess around!
For scientists and automation and test engineers, this is a very promising tool - and you can pick up one from Digi-Key for immediate shipment right now! There are four 'versions' of this product (https://www.digikey.com/en/products/result?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANogCcYADAMwDsIAuoQA4AuUECAC%2BYoA): you can get 2 or 4 analog input and with or without probes. For many uses, ADP3250 2-input version without probes will do a fine job (https://www.digikey.com/short/vmvw4mv3) but check out the other options before checking out. Order today and you can be automating your data acquisition by tomorrow.

This week's EYE ON NPI is a big time upgrade - we're featuring GAPTEC's LC78 series switching regulator modules (https://www.digikey.com/en/product-highlight/g/gaptec/lc78_3-0-series-switching-regulator) with up to 28V inputs, 95% efficiency and 3 Amp outputs!
There's two things we dig about these modules. One, they are pin-compatible with 78xx regulators that we all grew up on. So you can use them to quickly update existing designs from linear to switching power supply. Second, they are extremely easy to use, with ultra-wide input voltage ranges, various output voltages and current outputs if needed. (https://www.digikey.com/en/products/filter/dc-dc-converters/922?s=N4IgTCBcDaIOYEMAOAXApgYwAQBsMHYAOEAXQF8g)
Why use these instead of just DIYing a switching regulator layout? After all, we've covered many great DC/DC controllers on EYE on NPI! Well, to start - laying out and specifying switching regulators is a real pain for folks who are not experienced with some of the pitfalls and it's very very easy to make a mistake that can smash your regulator or have noisy output or have less efficiency/output than expected. For some high current outputs, you may need to update to 2 oz copper, 4 layer boards, or have heat sinking vias. (https://www.electronicdesign.com/power-management/power-delivery/whitepaper/21120734/minimizing-powersupply-voltage-drop-on-pcbs) If your board is large enough, making the whole thing 4 layer or 2 oz just for the regulator outweighs the cost savings of DIY.
And of course, it's adorable that these li'l DC/DC bricks are pin-and-size compatible with the standard 78xx regulators that have been used since the beginning of time. (https://www.digikey.com/en/products/detail/stmicroelectronics/L7805ACV/585962) That makes them a good choice when repairing or upgrading existing designs. The GAPTECH LC78's have much much better efficiency, allowing folks to use a wide range of voltages without worrying about heatsinking or air flow. (https://www.digikey.com/en/articles/heat-sinks-a-step-by-step-guide)
I'm a huge fan of these kinds of upgrade modules, because they solve a problem neatly and easily. These have a massive 3 Amp output, a non-trivial amount of current to manage with a linear or DIY switching setup. At that current range these could work great for robotics, large quantities of LEDs, running single-board computers, etc. all in a compact module. These are available in both 5V LC78_05-3.0 (https://www.digikey.com/en/products/detail/gaptec-electronic/LC78_05-3.0/13692361) and 3.3V outputs LC78_03-3.0 (https://www.digikey.com/en/products/detail/gaptec-electronic/LC78_03-3.0/13692290) for immediate ordering. Order the GAPTECH LC78 series modules today,(https://www.digikey.com/en/products/filter/dc-dc-converters/922?s=N4IgTCBcDaIOYEMAOAXApgYwAQBsMHYAOEAXQF8g) and you could have your power supply up and running by tomorrow morning!

Woo it is sweltering, which means we got to stay in and do a bunch of engineering. This week we spent a little time finishing up some languishing boards - Stemma QT version of the SCD40/SCD41 and IS31FL3741 chips - we wrote libraries for both as well! We also are dealing with a massive SAMD51 shortage by redesigning some recent boards like the Matrix Portal to be S2 only (so at least there's only one chip to source!)

This week's EYE ON NPI can handle the pressure of being featured - it's the ICP-10111 Barometric Pressure Sensor (https://www.digikey.com/en/product-highlight/i/invensense/icp-10111-barometric-pressure-sensor) with astonishing accuracy that makes it excellent to use as an altimeter. According to TDK, this "pressure sensor can measure pressure differences with an accuracy of ±1 Pa, an accuracy enabling altitude measurement differentials as small as 8.5 cm, less than the height of a single stair step." 1 Pa is really good and competitive in the market .
Even though we call this an altimeter, its technically a pressure sensor that uses the changes in pressure over altitude to compute. Earth's ambient barometric pressure changes with altitude - because air gets thinner the higher you go. (https://en.wikipedia.org/wiki/Atmospheric_pressure) There's a simple calculation that can be used to determine relative altitude changes and, if you know the sea level pressure (which usually doesn't vary much) you can use that to determine the absolute altitude. The better and more accurate your pressure readings, the better your altitude calculation output.
GPS can also be used to calculate absolute altitude, by measuring timing differences from 3 or 4 orbiting satellites. (https://www.gps.gov/systems/gps/performance/accuracy/) However, GPS only has an accuracy of about 10 meters, which is good for large equipment like planes but not good for humans, who are only about 2 meters tall. Also, of course, you need to have GPS fix which consumes a lot of power and requires one to be outdoors. Often times, even if a system does have GPS, a pressure-sensing altimeter will be included in the system. Also, pressure sensors can of course be used underground or underwater - try getting a GPS fix there!
This isn't a new kind of sensor - we've stocked a wide range of barometric sensors over the years such as the popular BMPxxx (https://www.digikey.com/en/products/detail/adafruit-industries-llc/2651/5604371) and the DPS310 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4494/11569124). But this one seems to have improved the precision, with an impressive 1 Pascals at around sea level instead of the common 2 or 3 Pascals. This apparently can give you ~10 cm differential measurements. Note that this is differential not absolute - you can tell if you've gone up or down and by how much, but it doesn't necessarily translate to precision absolute measurements (which is a different specification).
One nice improvement over most sensors we've seen is that these come in four packaging options: physical size/pinout variations in 2x2mm and 2x2.5mm and then waterproofed to 1.5m depth versions with three micro-laser-drilled holes in the top. Obviously the PCB that the sensor attaches to may not be easily waterproofed, but this sensor could have a gasket covering it, or it could just be less sensitive to ingress moisture and dust.
Another big deal is...all four ICP-10111 versions in stock at Digi-Key! (https://www.digikey.com/short/r248d9n8) Right now most of the other sensors we like to use are totally unavailable due to parts shortages, but you can get some of these sensors and they seem to be I2C-usage pin-compatible with the BMP280/DPS310 and BME390. Note the SPI pins are NC/reserved so its not purely pin-compatible, and of course there's some firmware updates you'll need to code up. So if you need a altimeter, and want one with waterproof casing, these could be an easy swap into an existing design to upgrade it! Order today an you could have them in hand by tomorrow morning.

The Adafruit crew will host the Hack Chat on Wednesday, July 21 at noon Pacific / 3pm EDT
https://hackaday.io/event/180454-python-your-keyboard-hack-chat-with-adafruit
Especially over the last year and a half, most of us have gotten the feeling that there's little distinction between our computers and ourselves. We seem welded together, inseparable even, attached as we are day and night to our machines as work life and home life blend into one gray, featureless landscape where time passes unmarked except by the accumulation of food wrappers and drink cans around our work areas. Or maybe it just seems that way.
Regardless, there actually is a fine line between machine and operator, and in most instances it's that electromechanical accessory that we all love to hate: the keyboard. If you buy off the shelf, it's never quite right -- too clicky, not clicky enough, wrong spacing, bad ergonomics, or just plain ugly design. The only real way around these limitations is to join the DIY keyboard crowd and roll your own, specifically customized to your fingers and your needs -- at least until you realize that it's not quite perfect, and need to modify it again.
Hitting this moving target is often as much a software problem as it is a hardware issue, but as is increasingly the case these days, Python is ready to help. To go into depth on how Python can be leveraged for the custom keyboard builder, our good friends at Adafruit, including Limor "Ladyada" Fried, Phillip Torrone, Dan Halbert, Kattni Rembor, and Scott Shawcroft will stop by the Hack Chat. We suspect they'll have some cool stuff to show off, in addition to sharing their tips and tricks for making DIY keyboards just right. If you're building custom keebs, or even if you're just "keyboard curious", you won't want to miss this one.

(No In The Weeds this week.)
We got a request on discord from someone with a 3D printer that needed new fans. In particular, they want a quieter fan, and one that can run directly on 24V without needing a regulator (e.g. a 12V fan). Let's visit the massive collection of fans over on Digi-Key and show how we can pare down the selection, then sort by specifications to get some great options to try.

This week's EYE ON NPI can handles whatever the weather throws at it - with the Stewart IP67 Rated USB Type-A Cable Assemblies (https://www.digikey.com/en/product-highlight/s/stewart-connector/ip67-rated-usb-type-a-cable-assemblies).
I absolutely adore using common, off-the-shelf connectors and hardware - like a Raspberry Pi or Arduino - for hardware designs. But, of course, most hardware you buy is not weather-proofed by default because it's expensive and restrictive. So instead, often times the final integration step is where durability is added by the designers. That's where these cables come in.
Instead of re-designing or re-building your existing cable connectors to use specialized weatherproof contacts, here we are supporting the common USB type A cables that are used everywhere for connecting accessories to your single-board computer. Now you can tuck away the Raspberry Pi or BeagleBone you've got in any enclosure you fancy.
The Stewart IP67 cables come in a few different flavors, so you'll want to mix and match the right kinds to get the ends and threading right. For example, there's USB 2 (https://www.digikey.com/en/products/detail/stewart-connector/67U2AC-006-K/14300409) and USB 3 (https://www.digikey.com/en/products/detail/stewart-connector/67U3AA-006-K/14300411), USB Type A plug (https://www.digikey.com/en/products/detail/stewart-connector/67U2AD-006-K/14300402) and Type A socket (https://www.digikey.com/en/products/detail/stewart-connector/67U2BD-006-K/14300407), and you can get them with cut ends or connector ends.
These cables come with an environmental rating (e.g. weather/waterproofing rating) so you know exactly what kind of use cases they are safe for - otherwise known as an IP rating (https://www.iec.ch/ip-ratings) IP67 means that the connector, once properly installed is completely dust-tight (that's the 6, maximum rating possible) and protected against rain, jets of water, and even temporary water immersion. That's the 7 part in IP67. It's not meant for being dunked in water for extended periods of time - like in a pool or aquarium - you'll need IP68 for that. Of course, the higher the rating the more expensive the connectors. Compare the rating to every day electronics which naturally have an IP rating of maybe IP30, with only the most basic dust prevention and no water protection.
Check out all the Stewart IP67 USB cable assemblies (https://www.digikey.com/en/product-highlight/s/stewart-connector/ip67-rated-usb-type-a-cable-assemblies) to make your own plug-and-play secure USB system with all off-the shelf hardware - it'll make weatherproofing your design easy! And they're all in stock right now at Digi-Key for immediate shipment (https://www.digikey.com/short/7r5t1m7d) - order today and you'll be ready to ruggedize by tomorrow morning.

For our RTC QT breakouts, we want to add a coin cell holder on the back. I like these bent metal ones, they are inexpensive, easy to pick and place or hand solder, and are incredibly durable - they don't corrode or get loose over time (and if they did you could bend them right back!)

Over the weekend I made some generative ai art using VQ-GAN + CLIP tutorial and Google Collab Notebook. It’s a bunch of Python that can take words and make pictures based on trained data sets.
This one is the word “Adafruit”, so this is what the output is based on the training. I made a short video of it before I was able to do an automatically made video after its iteractions.
Download 40
It starts out as a little LED looking thing, and eventually evolves to some goth looking cosplay thing and then pink hair grows out of it. It’s on a table with some tools, parts, and some fruit. Not bad, if I showed this someone in the electronics world and asked what company is this, they’d probably say Adafruit.

We're back from a break last week, and jumping into some hardware designs we put together before we took last weekend off. Two RTC QT designs - starring our two favorite RTC chips - the DS3231 and the PCF8523! We also started adding UPDI support to the AVR programmer library we use for computer-less programming. Thankfully we are able to use the open source port of pymcuprog from brandanlane: https://gitlab.com/bradanlane/portaprog and with a little noodling, have got some data going back and forth.

Could this week's EYE ON NPI help you with communicating with far away I2C sensors and devices? Yes, indeed it CAN! This week we're featuring the Analog Devices LT3960 (https://www.digikey.com/en/product-highlight/a/analog-devices/lt3960-high-speed-transceiver), a handy chip that will let you take advantage of the noise-durability of CAN with the universality of I2C.
The LT3960 is a high-speed transceiver which creates the functional equivalent of a single-master I2C bus in the CAN physical layer and is powered from a single wide-ranging input voltage. Using two integrated CAN transceivers, the LT3960 creates a differential proxy for each of the single-ended I2C clock and data signals which is capable of traversing harsh or noisy environments across two twisted pairs.
Please note! The LT3960 is not a I2C to CAN bus converter/adapter. It isn't like your CAN devices will appear on an I2C bus or vice versa. It's just a physical-layer converter: basically it lets you use your existing I2C controllers and peripherals but without the restrictive single-ended transmission layer:
It should be noted that while the LT3960 uses the CAN physical layer to conduct bidirectional I2C data, the CANSCL and CANSDA buses created by the LT3960 are not traditional CAN buses carrying traditional CAN data. As such, the CANSCL and CANSDA buses between LT3960 devices cannot be shared with standard CAN transceivers in a multidrop configuration.
However, you can (ha!) have multiple I2C sensors on the end of the long cable, either by having multiple sensors connected to one LT3960 or multiple LT3960's tied to the I2CAN bus along the route. A nice touch is the separate VIN pin, connected to a high-voltage LDO that can drop 60V down to 3.3V so you could also pass a high voltage power signal down the cable that could be then regulated at the end, locally, to provide power to the transceiver and sensor.
This could do a great job for automotive/robotics/industrial/agricultural sensor systems with long distances or electrically-noisy environments, without having to go to wireless or having 'smart' nodes. OK so why not just use CAN bus straight-up, instead of this converter? Well, I2C is the vastly more popular protocol for a variety of sensors and devices - it's supported by every microcontroller and microcomputer we've ever seen. If you wanted to use CAN, you'd have to connect an existing I2C sensor to a microcontroller/computer with CAN and then write and support the converter firmware. But most low cost microcontrollers don't have native CAN - it's considered an advanced peripheral, so now you have to go with a pricey chip like the STM32F405 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4382/10673113) or you could try tacking a CAN converter chip (https://www.digikey.com/en/products/detail/microchip-technology/MCP2515T-I-SO/593681) onto your existing nodes, also not cheap and now adds another failure risk.
So whether you're using an Arduino UNO, STM32F405 or Raspberry Pi main controller or data logger, you can take advantage of the existing I2C controller you've already got. Then use this low cost chip on either side of your sensor network to create a durable network without the added complexity of having I2C-to-CAN nodes.
So for example, if you have a greenhouse with a plethora of SHT30-based soil sensors (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4099/10230011), each on I2C, you can stick this chip on the end of each sensor and voila, the data can be run all the way to the end of the building (and with that 60V LDO, your CAT-5 cable (https://www.digikey.com/en/products/detail/amphenol-cables-on-demand/MP-5ERJ45UNNB-003/6052293) can provide power too).
Sprinkle a few of these over your design and sweep away your EMI and stray capacitance problems with no change in firmware. This NPI just dropped, so sign up at digikey.com to be notified the moment the LT3960's (https://www.digikey.com/short/9wp0j1f5) are in stock!

The Great Search - Tapes & Tubes, oh my! https://www.digikey.com/short/9w4bw2r5
Today we were tasked with finding some MAX31856 chips. We had a reel on order from Digi-Key but it hadn't shipped yet and we're almost out of chips. After a little investigation I found that the tubed version is in stock, but not the taped. Now, our pick and place doesn't like tubes at all, but we can get the parts taped! Tune in to find out how we do it.

This week's EYE ON NPI is hittin' the books - we're featuring the Digi-Key Electronics Innovation Handbook (https://www.digikey.com/en/resources/innovation-handbook) this week - which was just released so it's very New and Fresh. We just got ours in the mail!
The Digi-Key Innovation Handbook is your guide to keeping some of the most highly referenced content from Digi-Key at your fingertips while giving you plenty of room to keep your thoughts, projects, and ideas at hand. We highlight concepts, formulas, components and electronic staples so you can refer to them at any time. From reference tables and schematic symbols to resistors through Raspberry Pi’s the Innovation Handbook is the first place to look for all your project needs. It also includes over 120 grid-lined note pages for you to use any way you see fit. Of course, we couldn’t fit it all in the book so below you will find additional information to go more in-depth into each of the topics included in the printed edition.
This book is reminiscent of the Maker Notebook that Make Magazine released many years ago (https://www.digikey.com/en/products/detail/o-reilly-media/9781680456639/13625835). Its still a great notebook, and has a hard cover which we love - so you have reason to buy both! The Innovation Notebook has some overlapping information, but is much more up to date. For example, it's got modern board pinouts like Feather, Teensy and Raspberry Pi. There's even the new RP2040 Pico! The resistor diagram is in full color (which really helps since the number bands are rainbowy). There's also a lot of reference parts - so if you just need "a servo" or "an SMD red LED" there's part numbers ready to go for you to reference. I'm a huge fan of that because there's definitely the most popular of each part, and for many makers and beginners, they should just get that part rather than spending a lot of time in the Digi-Key search system.
In the front, there's 40 pages of references and diagrams, and then there's 120 gridded pages, so it's definitely designed to be a scientific/design notebook, not just a technical reference. Right now it's V1.0 of the book, and there's probably a lot more stuff that they could add or improve. Please feel free to send comments, thoughts and future recommendations to support@maker.io to help make sure the next edition is even better.
This notebook makes for an excellent gift for any student or maker, and at a great price. If you've got a cart going at Digi-Key, you can add one of these in - there's hundreds of Innovation Notebooks in stock right now (https://www.digikey.com/short/mf58fmj8) and at least books aren't impacted by the component shortage! If you want to check out the PDFs or other engineering resources, visit https://www.digikey.com/en/resources/innovation-handbook for online tools, calculators, printouts and more.

In this tutorial we'll take a look at using the sweep feature to create snap fit enclosures. I walk through sketching out snap fit geometry and trouble shoot some oddities with using chain selections in a path. The kitty paw enclosure required some clearance to accommodate for the QT Py RP2040 micro-controller so each side has specific snap fits.

Designing hardware during the parts shortage is really challenging - you need to spec parts but there's now a risk you won't be able to get it.
Historically this maybe meant a delay of a few weeks or at worst, months. Now some parts are delayed 2 years! We're revising some designs we were about to launch with 'flip flop' designs - where we lay out two alternative packages.
We don't know the official name for this technique, we borrowed it from fixies https://en.wikipedia.org/wiki/Flip-flop_hub Let's take a look at how we picked the packages and how we laid out the design to accommodate 'em.

We've been using the IS31FL3731 for a while to do monochromatic LED driving/dimming. But for RGB LED driving, we need moar channels! So we're trying out the IS31FL3741, which can handle an astonishing 351 individually-dimmable LEDs in 39x9 matrix. Divide by three for RGB LEDs, and you've got a 13x9 24-bit color display, all controllable over I2C! Next we'll design a STEMMA QT breakout...

This week's EYE ON NPI is super-brainy but also good looking (or maybe it's good at looking) - the Intel RealSense Camera Depth module (https://www.digikey.com/en/product-highlight/i/intel-realsense/id-solution-f450-f455) is ready for embedding in your product to add instant facial recognition with excellent quality hardware and software from Intel.
Long-time viewers of EYE ON NPI know that we're suckers for sensors and edge computing (https://en.wikipedia.org/wiki/Edge_computing) AI products - devices with machine learning capabilities (https://en.wikipedia.org/wiki/Machine_learning) that can function without the use of Cloud Computing or internet connectivity. Why?
1) More security controls: if it can't connect to the internet, you don't have to worry about data being used elsewhere by people who aren't supposed to have it
2) More privacy controls: if it can't connect to the internet, you don't have to worry about data being used elsewhere by the people who are supposed to have it but maybe are planning on selling it or misusing it
3) Installation and usage flexibility: can install it in places without good network connectivity, don't have to worry about a Verizon outage taking your product down.
There's also other important parameters that may be improved by edge computing: lower power, smaller PCB, lower cost, no subscription fees. All good stuff!
This platform is available in two packages: one is a slick USB-connected rectangle (https://www.digikey.com/en/products/detail/intel-realsense/82635DSF455/13670508) that can be mounted with a 'camera tripod' 1/4-20 screw, and one that's a bare PCB with a FPC connector (https://www.digikey.com/en/products/detail/intel-realsense/82635DSF450/13670511). That's really neat in our opinion because it means you can use this technology with an every-day computer by plugging it into a USB port or doing a full integration into your product design.
We picked up one of each. Of course, if you're just getting started, you may want to go with the all-enclosed one since its so easy to get going. We downloaded the Windows enrolling software (you can also enroll via the API, but this is a nice app) and updated the firmware. Then we practiced enrolling. Enrolling a face is always going to be a little annoying because it really needs to get good data. You really want to be close up, and have your head straight-on to the camera. It took a few tries, however once done it worked great during detection even when far away.
We previous covered RealSense on EYE ON NPI, but that was with a LIDAR camera. (https://blog.adafruit.com/2020/09/17/eye-on-npi-intel-realsense-lidar-camera-eyeonnpi-lidar-digikey-digikey-intel-adafruit/) This uses two every-day cameras to do depth calculation, so it's a lot cheaper and smaller. The module is only a few mm thick!
The thing that really sold us on this module is the simplicity of usage - once you've got people enrolled, everything is done through a serial port/UART. That makes it incredibly easy to integrate into any kind of system - from a microcontroller to a single board Linux computer to a desktop running MacOS. And there's a full API for RealSense (https://github.com/IntelRealSense/RealSenseID) on the Intel GitHub repo (https://github.com/IntelRealSense). The 54-pin FPC connector on the module exposes pretty much everything on the PCB assembly.
Best of all, the price of the full products is really low - it would be hard to DIY your own solution for less than the $87 each module costs. And with the heavy lifting of the face recognition done completely on this device, you can reduce the complexity of the rest of your design. Like, literally you could integrate this into your design in less than a week.
Both the Intel RealSense F455 starter kit (https://www.digikey.com/en/products/detail/intel-realsense/82635DSF455/13670508) and the bare bones Intel RealSense F450 PCB (https://www.digikey.com/short/v9pw7nq5) are available and in stock right now at Digi-Key! Order today and add solid, dependable, secure face-recognition to your product by tomorrow afternoon.

USB controllable panel mount and tower-light samples
What can we say, we like tower lights and other notification systems. But they're often 12V and require a controller. These alerts are panel-mount friendly AND come with a USB cable for power and data. When plugged into a computer or Raspberry Pi they appear as a serial port. Send bytes over to turn on the red, yellow or green LEDs, the tower lamp also has a loud buzzer which we only turned on for 100ms because its SUPER LOUD and we don't want to annoy anyone around :)

We sure love smart addressable LEDs here at Adafruit - like NeoPixels (https://www.digikey.com/en/products/result?s=N4IgTCBcDaIHYFMD2AHAlgDwQGxAXQF8g0 and DotStars (https://www.digikey.com/en/products/result?s=N4IgTCBcDaICYHsAuBnJBDATiAugXyA)
But our new project is going to use the IS31FL3741 (https://www.digikey.com/short/8q0nmn25) driver to control a large quantity of RGB LEDs. Let's find a low cost SMT RGB LED that we can use with this chip!

Check it out - today we're testing the ESP32-S2 Kaluga dev kit v1.3 with the latest PR from Jeff to add native camera support to CircuitPython. https://github.com/adafruit/circuitpython/pull/4880 In only a few lines of code we can initialize a display, read a buffer from the camera, then blit it out to the onboard 240x320 screen. We now have libraries for both OV7670 and the nicer/newer OV2640 https://github.com/adafruit/Adafruit_CircuitPython_OV2640 Amazing work by our team to get this so smooth!

In this tutorial I walk through creating a curvy rectangular shape using the spline tool in Fusion 360. I show how to use symmetrical and equal sketch constraints to create a shape thats flexible and parametric. Whenever one side of the shape is effect, the other side is perfectly mirrored. One corner of the shape features a bezier handle with a sketch dimension (length and angle) making it easy to adjust a single corner and automatically update the other three. This technique was used in an upcoming project that uses spline curves to create a kitty paw shape. I personally have found the spline tool one of the more trickier to tame and this project has brought me more understanding of how to better manipulate and control splines in fusion 360.

Dan just dropped a new PR with our event-based key switch vector/matrix handling all done in the CircuitPython core https://github.com/adafruit/circuitpython/pull/4891 which will make keyboard projects a lot easier and a TON faster. Matrix/vector scanning is now done in a background interrupt and can handle all the work for you and emit key press/release events. Here I've got it with my 5x6 snap-apart ortho matrix keyboard PCB, which has 30 keys - 5 rows and 6 columns in a diode matrix. Even with so many keys, its super snappy! beep boop

This week we've got a few things we've been hacking on. We tested out jepler's ESP32S2 camera support in CircuitPython. It works really well! Now that we have OV7670 and OV2640 camera modules supported we can move on to designing some hardware. We also wrote up a ISSI IS31FL374x (https://www.digikey.com/short/8q0nmn25) driver which is a more powerful version of the IS31FL3731 chips what we've used for our charlieplex wings. This driver can handle 160 independent RGB LEDs with constant-current adjustment and 8-bit PWM per LED. We would use these for boards that have more than ~50 NeoPixels/Dotstars because 'smart' LEDs are about 10 cents each on reel. The Great Search - Non-Addressable SMT RGB LED https://www.digikey.com/short/vf2hvqtv
We sure love smart addressable LEDs here at Adafruit - like NeoPixels (https://www.digikey.com/en/products/result?s=N4IgTCBcDaIHYFMD2AHAlgDwQGxAXQF8g0 and DotStars (https://www.digikey.com/en/products/result?s=N4IgTCBcDaICYHsAuBnJBDATiAugXyA) But our new project is going to use the IS31FL3741 (https://www.digikey.com/short/8q0nmn25) driver to control a large quantity of RGB LEDs.

The code is now twice as fast since we're no longer spending 4ms just for checking whether switches are pressed!

The Adafruit Clue is powered by an nRF52840, which has bluetooth capabilities and a powerful Cortex M4 processors with lots of RAM - so it's great for doing machine learning projects. Here we've got it working with https://experiments.withgoogle.com/collection/tfliteformicrocontrollers which will allow downloading of models over BLE (neat!) and also training of custom models. Since we have the display available, we can also show status and inferences to the user.

Adafruit seesaw is a near-universal converter framework which allows you to add add and extend hardware support to any I2C-capable microcontroller or microcomputer. Instead of getting separate I2C GPIO expanders, ADCs, PWM drivers, etc, seesaw can be configured to give a wide range of capabilities. And now we've got our seesaw peripheral library ported to Arduino IDE & humming along nicely - here's a demo where we have an I2C controller read a trim potentiometer over I2C, then turn that into NeoPixel brightness settings and pipe out a rainbow demo to a NeoPixel strip over I2C.

It's getting hot here in New York City, we could use a little help cooling off, and this week's EYE ON NPI an ultra-cool blast of Nordic engineering - the nPM1100! It's the first power management IC from our favorite low-power-wireless company, Nordic Semiconductor.
We've featured them on EYE ON NPI before - the Nordic Power Profiler Kit II (https://blog.adafruit.com/2020/12/03/eye-on-npi-nordic-power-profiler-kit-ii-eyeonnpi-digikey-nordictweets-digikey-adafruit/) and the nRF53840 microcontroller (https://blog.adafruit.com/2020/03/20/eye-on-npi-nordic-semiconductors-nrf5340-bluetooth-eyeonnpi-maximintegrated-digikey/) - and we've been using Nordic BLE chips for quite a while in our Bluefruit line of boards (https://www.digikey.com/en/products/filter/rf-evaluation-and-development-kits-boards/859?s=N4IgTCBcDaIEYBsCuBTAZgJyQSwC4gF0BfIA) For us Nordic is synonymous with Wireless and Low Power. That's their bag, and if you need something that's BLE and runs on a small battery for a long time, it's probably the product like you're going to use. Even Apple, who have gotten serious into designing their own silicon used the Nordic nRF52 series for the AirTag (https://www.ifixit.com/News/50145/airtag-teardown-part-one-yeah-this-tracks)
When you make products that are designed and marketed to be used for low power wireless - like motion trackers, beacons/tags, fitness watches/bracelets, environmental monitor, etc. the power management system becomes less of a independently-run subsection of the electronics design. As we've seen in other EYE ON NPI's, there may be times when you drop the voltage down or raise it up to change quiescent current and RF transmission. A lot of Cortex chips we've seen lately have integrated buck converters that can be enabled/disabled on demand - they have higher quiescent current than LDOs, but may have lower overall run current during high draw. Buck converters also require an inductor, of course, and will have higher noise. Getting long life from battery is very hard, much harder than people think, and requires good firmware, hardware and integration design. Given the creating of the PPK2, it seems obvious to us that a lot of Nordic's time has been spent trying to get their their customers going with the battery performance they need without doing their design for them. A lot of time folks don't understand the way quiescent currents add up to drain batteries.
To solve this for Nordic's customers, they've pulled the PMIC's that were historically integrated into the nRF52840 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52840-QIAA-R7/11200025), nRF5340 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF5340-QKAA-R/13559661) and nRF9160 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF9160-SICA-R/12339212) and super-powered it into the nPM1100 (https://www.digikey.com/short/38n9f9dv) - an all-in-one battery charger, regulator and buck converter. Ultra-small form factor PMIC 2.075 x 2.075 mm WLCSP package 400 mA battery charger Termination voltage: JEITA compliant 4.1 V or 4.2 V selectable Charge current: 20 mA to 400 mA Highly efficient Buck regulator Output voltage: 1.8, 2.1, 2.7 or 3.0 V Current limit: 150 mA output USB compatible input regulator Overvoltage protection Ship mode disables power output Quiescent currents: 800 nA typical, 460 nA in ship mode Drivers for charge and error LEDs -40°C to 85°C operating temperature
Things we like - this chip is fully standalone and strapped with resistors or pins so you don't have to configure it over I2C or 1-Wire or anything and two direct LED outputs for instant visible feedback with a bi-color LED. Works with USB but has input protection for higher voltages in case something gets mis-plugged. Three-in-one integration design means you can pick and choose the pieces you want. It's clearly designed for boards that use sporadic power, and has a 'ship mode' to reduce power draw while its in storage/shipment to the customer - many of these devices don't have a true Off button/switch, so before the first use they'll want to be disabled/enabled with soft-switch buttons to wake up. In Nordic's case studies, they were able to up the run time of a wearable health-monitor bracelet by taking advantage of the buck converter to reduce run-time quiescent current.
While designed for Nordic wireless chipsets, this PMIC would be well suited to wearable/low-power designs and you know that Nordic takes low power very seriously so this chip will hit the ground running with a tiny chip that does it all.
Bare nPM1100 chips (https://www.digikey.com/short/5dwz72j7), as well as the eval boards (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NPM1100-EK/14310011?s=N4IgTCBcDaIHYAcC2BGFAGdIC6BfIA) are in stock right now for immediate shipment! Order today and you can integrate into your low-power design to reduce space and increase battery life all at the same time.

We're slowly getting through to all the things we coded up for seesaw https://github.com/adafruit/seesaw and porting it to our Arduino-library-version here https://github.com/adafruit/Adafruit_seesawPeripheral . We've got digital in and out, now doing analog input. Thankfully, we should be able to quickly adapt to other chips that have Arduino core support which will make development/debugging easier.

Build a smart DIY fume extractor with an Adafruit FunHouse and CircuitPython. Use a PWM fan and the EMC2101 controller to change the speed based on readings from an SPG30 air quality sensor.
Learn Guide https://learn.adafruit.com/funhouse-fume-extractor/
Project video by Liz https://youtu.be/3rwHkWDBnlA
Use CircuitPython libraries and ESP32-S2 to connect to WiFi and log sensor data to a feed and display it on a dashboard with Adafruit IO. Use the FunHouse’s built-in TFT to display bitmap graphics with fan speed and air quality. Use the built-in buttons to select options like choosing to log data. CircuitPython makes it easy to customize features, experiment with other hardware and quickly iterate.
The electronics are housed in a 3D printed enclosure that snap fits together. Use a carbon activated filter to adsorb smoke from solder fumes. The fan controller and air quality sensor are connect with STEMMA QT cables for a plug-and-play circuit. A mini fan mounted in front of the air quality sensor directs fumes for sampling and measuring. The ports on the FunHouse make it easy to power 5V peripheral.

Catching up to a project we started last month - we need to redesign some of our boards due to the chip shortage. We decided to move from the SAMD09 to the ATtiny816 (https://blog.adafruit.com/2021/05/18/the-great-search-a-very-inexpensive-seesaw-8-bit-microcontroller-thegreatsearch-digikey-digikey-adafruit-microchipmakes/) because it seems available/low cost and capable enough. Once you've spec'd the chip, it's nice to get an eval board or two. This will get us going quickly! I'll share some tip for what I look for in an eval board, as well as how to find an eval board even if one doesn't exist for your chip (!)

Seesaw is an open source microcontroller friend for other chips. It provides a variety of capabilities such as UART, ADC, DAC, extra GPIO, etc. to chips that don't have them. We've used the SAMD09 for seesaw for years, and it's been great. But now we can't find any SAMD09 on the market for a year or two - so it's time to redesign! We're going with the ATtiny817 and megaTinyCore https://github.com/SpenceKonde/megaTinyCore with great success so far!

OK it was a little rainy out yesterday so we finally got around to porting our CMSIS/arm-gcc 'seesaw' core over to Arduino. Thankfully https://github.com/SpenceKonde has written an awesome Arduino core for this chip so we were able to get up and running very quickly! Check out their tindie at https://www.tindie.com/stores/DrAzzy/ Using an eval board for the tiny817, and some CI tooling, we quickly added support for almost all of the seesaw commands and published the code. We'll also show how we will customize firmware with #define's

This week's EYE ON NPI is all in on keyboard hacking, just like us! The Mill-Max 3305 series open bottom, low-profile, solder mount receptacles are specifically designed to make mechanical key switches hot-swappable. The 3305 series is designed to be soldered into a 0.060” (1.50 mm) minimum mounting hole with an ultra-thin retention shoulder so plugged-in components sit nearly flush to the board surface. The open bottom design is meant to accommodate varying lead lengths, making this a very versatile receptacle.
These sockets are popular in the keyboard building and modification community for allowing folks to have PCBs that allow socketing or direct-soldering of switches without any height changes or PCB layout changes. Compared to previous sockets manufactured by Mill-Max, the 3305's are lower profile and have gold plating for long-life reliable contacts.
Cherry MX switches (https://www.digikey.com/en/products/detail/cherry-americas-llc/MX1A-E1NW/20180) have a standardized pinout, with a large center hole - two optional side-stability holes and two normally-open contacts. Cherry offers a wide range of switches with the same pinout/physical shape but with different mechanical attributes - some are smooth/linear, some are loud and clicky. Of course, many people like to customize what the switches are on a keyboard. Now, hopefully your keyboard manufacturer comes with different options for keys. but maybe you're doing a build or its an older design you want to update. You can carefully de-solder switches to replace them, but it's much better to socket them like we do with chips. (https://www.adafruit.com/product/2203)
Sockets do exist for MX switches, (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4958/13997772), at this time both Gateron and Kailh make em. The good news is they work quite well - but they do require a new PCB layout for the SMT pads. All good for folks making new designs. But, sometimes you don't have the ability to change the design - or for some constraint reason you don't want to use these sockets. That's where the Mill-Max 3305's come in! (https://www.digikey.com/en/product-highlight/m/millmax/3305-series-open-bottom-receptacles)
These ultra-slim ferrules can be soldered into existing plated through holes that are made in a PCB design. After soldering them in, two per switch, they accept the rectangularish contacts on MX and compatible switches. Best of all, they come in pick-and-place tape so you can integrate these into your manufacturing process or solder by hand. Now, you might be thinking "this seems really specialized to a specific purpose, why bring this up on EYE ON NPI?" Aha, because while these are designed for use with MX switches, these could be used to socket all kinds of through hole parts without changing PCB layout or height. For specialized parts, sensors or tubes or specialized displays, there may not be a plug-and-play ready to go socket available. But you still don't want to solder it right into your PCB? Check the lead sizes...you may be able to use these inexpensive sockets! Best of all, since they're open-bottom you can go with any length chip lead.
Various lengths of Mill-Max 3305 sockets are in stock right now at Digi-Key for immediate shipment. (https://www.digikey.com/short/45bfzdj7) Order today and you can start socketing securely by tomorrow morning!

For the KB2040 board we're working on, we want to add a PTC fuse. These fuses auto-'heal' after they cool down and they're pick and place friendly, so they're easy to use. We're going to add one to this board so it has similar behavior as the Pro Micro it is pin-compatible with. PTC fuses are available in a few different voltages, current ratings and sizes - let's find the one we need for this tight-fit PCB!

We put together our hopefully-final prototypes for the Macropad we're working on at the office. Now we're home and it's time to bring up the design. We like to do our bring-ups in Arduino, so we're using the Philhower Arduino core to make a definition and verify all the hardware works. The new part here is the OLED, which uses a new chipset, but similar enough to other OLEDs we wrote a driver pretty fast. This test program lights up all the switch neopixels, tracks the rotary encoder direction and pushbutton, and scans I2C connected to the Stemma QT port. So far so good!

This week on the Desk of Ladyada we're doing the bringup of our hopefully-final revision of the RP2040 macropad we're working on. Arduino is working solidly, and CircuitPython is getting there. We have to get the OLED driver bugs ironed out but the hardware seems solid! Next up, we've acquired a TI calculator running a fork of CircuitPython. Let's check it out and see what has been added.
The Great Search - SMT PTC Fuses https://www.digikey.com/short/24zcmdwc
For the KB2040 board we're working on, we want to add a PTC fuse. These fuses auto-'heal' after they cool down and they're pick and place friendly, so they're easy to use. We're going to add one to this board so it has similar behavior as the Pro Micro it is pin-compatible with. PTC fuses are available in a few different voltages, current ratings and sizes - lets find the one we need for this tight-fit PCB!

Now that we have my hardware validated in Arduino, it's time to get it running in CircuitPython as well. We needed to write a little patch to the core to fix a row/col swap so that the SH1106 driver will work right https://github.com/adafruit/circuitpython/pull/4864 however, once we got that fixed, the display/buttons/encoder are working perfectly. Next up maybe we can get the onboard audio working so that the final PCBs can be ordered.

We're back to working day-shifts in the office, which means access to our mega-oven for prototypes. We loved ya, lil reflow plate, but for bigger protos like this an oven really does a great job. We're pasting the components by with a syringe, then hand placing the parts for two protos. After a trip through the oven, we do a little hand-cleanup of bridged pads and then it's time to bring up the board!

We sure love our Cherry MX compatible switches, but let's be honest....they're kinda big. What if you want something svelte? The Kailh CHOC v1's are much shorter. Here are some samples we are testing out of clicky white and linear red Choc1's with two color options for keycaps and PCB sockets. Watch out - these are totally incompatible with MX-series sockets and caps! Still, so worth it for that low-low-profile.

This week's EYE ON NPI is easy-as-pie: it's the Raspberry Pi RP2040 microcontroller (https://www.digikey.com/en/products/detail/raspberry-pi/SC0908-7/14306009), finally available for purchase in tape and reel for manufacturing. The RP2040 is one of the most hotly-anticipated EYE ON NPI's of the year - it's been a few months since we've been enjoying the RP2040 in devboards. Adafruit has featured it in many popular dev boards like the QT Py RP2040 (https://www.adafruit.com/product/4900), Feather RP2040 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4884/14000603) and ItsyBitsy RP2040 https://www.digikey.com/en/products/detail/adafruit-industries-llc/4888/14115610). Thanks to the Raspberry Pi Foundation, Adafruit got a few early reels so we could develop our layouts and board designs - that whetted the appetites of a lot of developers who saw the massive number of designs available from Sparkfun, Pimoroni, Seeed and others and wanted to join in the fun! Well, now you can because Digi-Key is stocking the chips in reels for anyone to purchase. They're available in 7" reels (https://www.digikey.com/en/products/detail/raspberry-pi/SC0908-7/14306009) with 500 chips in a spool, or in 13" reels (https://www.digikey.com/en/products/detail/raspberry-pi/SC0908-13/14306010) with 3400 chips. At a cost of $1 each pre-quantity (quantity pricing is not yet determined)
For that $1, you get a lot of technology: RP2040 Chip features:
Dual ARM Cortex-M0+ @ 133MHz 264kB on-chip SRAM in six independent banks Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus DMA controller Fully-connected AHB crossbar Interpolator and integer divider peripherals On-chip programmable LDO to generate core voltage 2 on-chip PLLs to generate USB and core clocks 30 GPIO pins, 4 of which can be used as analog inputs Peripherals 2 UARTs 2 SPI controllers 2 I2C controllers 16 PWM channels USB 1.1 controller and PHY, with host and device support 8 PIO state machines The RP2040 uses the Cortex M0+ core, which is is good for microcontroller projects. It's not fast enough or capable of running Linux like a Raspberry Pi computer but it can run Arduino/MicroPython/RTOS pretty easily. To make up for the M0 core, the chip is run very fast, at ~130MHz, much faster than many of the Cortex M0's we've worked with that tend to run at 48 Mhz or so. Since it is an M0 chip, it does not have a floating point unit or DSP hardware support - so if you're doing something with heavy floating point math, it will be done in software and thus not as fast as a Cortex M4.
For peripherals, there are two I2C controllers, two SPI controllers, and two UARTs that are generously multiplexed across the GPIO - check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout). While its not a full crossbar-type chip, it's easy to find pins for your peripherals.
You'll note there's no I2S peripheral, or SDIO, or camera, what's up with that? Well instead of having specific hardware support for serial-data-like peripherals like these, the RP2040 comes with the PIO state machine system which is a unique and powerful way to create custom hardware logic and data processing blocks that run on their own without taking up a CPU. For example, NeoPixels - often we bitbang the timing-specific protocol for these LEDs. For the RP2040, we instead use PIO object that reads in the data buffer and clocks out the right bitstream with perfect accuracy. Same with I2S audio in or out, LED matrix displays, 8-bit or SPI based TFTs, even VGA! In MicroPython and CircuitPython you can create PIO control commands to script the peripheral and load it in at runtime. There are 2 PIO peripherals with 4 state machines each.
While the RP2040 has lots of onboard RAM (264KB), it does not have built-in FLASH memory. Instead, that is provided by the external QSPI flash chip. You will need to provide external FLASH memory using QSPI NOR memory. The flash chip is shared between the program it's running and any file storage used by MicroPython or CircuitPython. We like this GigaDevice chip (https://www.digikey.com/en/products/detail/gigadevice-semiconductor-hk-limited/GD25Q80CSIGR/9484688) but just about any QSPI flash memory will work just fine. You'll also need a 12 MHz crystal and lots of capacitors and some passive components to finish off the design.
With top-notch documentation, lots of board examples, firmware-aplenty, and of course a rock-bottom price, its an excellent chip to use for just about anything. Especially with the PIO peripherals, this chip can 'punch up' quite a bit and perform tasks or process data that normally would require much more powerful chips or advanced peripherals - things like cameras, TFT displays, motor drivers, PDM/I2S/PCM encoding and more. Sign up to be notified the moment the RP2040 chips are in stock at Digi-key here (https://www.digikey.com/short/8mt22d38)
JP loves showing off his keyboard projects with these "lamp" keycaps, with an opaque body and a clear plastic window. Gotta admit, they are slick and cyberpunk - we found a supplier and ordered three samples. These fit great and look cool, perfect for a cyberdeck build.

Looking at a lot of keyboard kits, we noticed that many use a diode key-matrix to connect lots of keys without a ghosting effect. We should probably source long tape strips of 1N4148s for folks making keyboards and key matrices! Let's talk about 1N4148s in two packages - DO-35 (classic glass) and SOD-123 as seen on a keyboard we purchased.

This week's EYE ON NPI will go the distance to help you with your object sensing needs - its the Omron B5W-DB Long-Distance Object Detection Sensor (https://www.digikey.com/en/product-highlight/o/omron/b5w-db-long-distance-object-detection-sensor). This sensor builds on decades of infrared-breakbeam sensing technology, so while it's not a radically new idea, it is a solid and trustworthy sensor with great quality.
Omron’s B5W-DB optical sensor improves on existing technology, and can detect objects over a half meter away. The B5W-DB offers an increased sensing distance of up to 800 mm depending on the object being detected. The B5W sensor series is a key component for object detection applications and touchless switches. This sensor operates the same as the previous iterations of the B5W object detection sensors by detecting a wide range of objects, no matter the color, reflectiveness, or transparency.
Features Increased range for object detection: Expanded range of target applications Small package can be installed in tight spaces without sacrificing internal real estate Material immunity: Detects a wide range of objects including white, black, transparent, and reflective Note that this isn't a distance sensor, it won't tell you how far away something is - it will just tell you when something is in front of the sensor.
This sensor has a surprisingly good distance rating of about 55 to 80 cm maximum. When something is in the way of the sensing beam, the output pin is driven low. You can connect the drive to an LED, alarm, solenoid driver, interlock, etc. VCC power is 12V, which isn't surprising because the LED is going to be pretty strong - you could probably get away with a lower 9V if you don't need the full distance rating.
The sensor is really good looking too, with a nice snapped-together body. It's not waterproof but it looks well protected against most indoor environmental damage. In particular, we like the mounting flanges with both lateral and vertical mounting holes! A cable socket on board makes for easy connection to your robotic project, use a ready-to-go cable harness part number EE-5002 (https://www.digikey.com/en/products/detail/omron-electronics-inc-emc-div/EE-5002-1M/8124128?s=N4IgTCBcDaIKJwLQFYAMqIF0C%2BQ) or you can DIY a custom-crimped cable using the JST GHR-03 plug (https://www.digikey.com/en/products/detail/jst-sales-america-inc/GHR-03V-S/807815?s=N4IgTCBcDaIOIAkBKBaADAZgGooMogF0BfIA)
A great looking sensor, which does one thing and does it well. With these sorts of sensors, in automation, you need ultra-reliability and Omron's a trustworthy brand that will give you a sensor that is repeatable and reliable.
The Omron B5W-DB1452-1 is in stock right now at Digi-Key for immediate shipment - order today and you'll be detecting things around your workbench by tomorrow!

Adafruit has recently spent time adding support for the new Adafruit FunHouse WiFi Home Automation Development board to Wippersnapper, our no-code interface for Adafruit IO. We wanted to show off how easy it is to build an Adafruit IO dashboard using your Wippersnapper device's components. It takes a little over a minute and with no code!
What is Wippersnapper? Wippersnapper is a no-code IoT interface for Adafruit.IO – it lets you turn any WiFi-capable board into an IoT device without any programming. Simply select what devices are connected to which pins on the hardware and it will auto-configure the firmware and even create an IO feed for visualization. Wippersnapper is not out yet but will be soon.

An older project of ours, the STEMMA Friend, has been reborn as an RP2040 board, we'll show off some of the projects we got working with it over the weekend, improvements to the Arduino API for faster SPI and why framebuffering is awesome if you hrave the RAM. We also got an Arduino Nano RP2040 Connect working thanks to BlitzCity's PR - with WiFi too! Mr Ladyada wants a Tube Trinkey, so I picked up some VFD 7 segments that maybe we'll try to trinkify The Great Search - LEMO 'aviator' connectors https://www.digikey.com/short/qz1h1pbr If you want really amazing push-pull connectors, nothing beats LEMO connectors. These are sometimes called 'aviation' connectors and they're luxurious, durable, and vibration proof. Did you know you can buy LEMO on Digi-Key? Lets find some DIY 'Mechanical Keyboard USB Cable' connectors!

The lil STEMMA Friend board we're working on this weekend could also be a cute lil UART/Serial monitor tool. the RP2040 has a fast enough GPIO peripheral that we can automatically detect baud rates and then turn on the UART peripheral to read data via an IRQ into a buffer. To get the nice scrolling effect (with a header at the top that doesn't scroll!) we have to use a framebuffer - thankfully the RP2040 also has enough RAM to buffer a full 240*240 pixels. we read the serial data and draw to the framebuffer in the IRQ and draw to the TFT itself in the main loop. We're testing it here with a 9600 baud GPS but it also works with a Raspberry pi. Maybe VT10x color coding is next?

We re-spun our STEMMA Friend design from a SAMD21 to an RP2040 to take advantage of the more-powerful chip, to make it CircuitPython-friendlier and faster at doing stuff like I2C sniffing. While porting over the Arduino code (which pretty much works just fine) we noticed the display is a little sluggish due to SPI data being sent over one byte at a time with a delay. So we're adding a bulk-transfer SPI function to the Philhower RP2040 core to take advantage of the pico-sdk's buffered writes - its now 10x faster!

Liz submitted a PR to add support for the Nano RP2040 to CircuitPython and we thought to try it out! So far so good, the digital pins all toggle right and we were able to see the built in LSM6DSOX chip on the I2C port. We have a driver for this IMU so hey, why not wire up a quick demo? We have an external OLED wired up on the same I2C bus, reading acceleration/gyro data and displaying it just fine. Check out the PR here! https://github.com/adafruit/circuitpython/pull/4802

After dinner we like to unwind with a tall glass of .. solder paste? sure why not! let's put together two quick prototype boards of a Trinkey that uses an RP2040 chip and fits in the same size and shape as our standard-issue QT sensor breakouts (1" x 0.7"). After stenciling on some paste we hand-place all the components. Then they get reflowed on our cute lil mini reflow plate. During reflow sometimes we have to poke at some parts to get them to sit flat. One at a time, and we're done! https://www.adafruit.com/minihotplate

Glider is a new app we're working on that will allow folks to program a CircuitPython board anywhere, with a mobile device like a phone or tablet (it will also work on desktops, but we sorta recommend USB ports if you have em) Glider sends and receives files over BLE using a simple protocol we've developed that is simpler and easier to implement than BLE's object-transfer-protocol. One of the nifty things about interpreted languages is that we can run new code by sending text files, no compilers needed - so this should work very nicely. Right now we're just doing protocol testing, here's us sending and receiving files. BLE can be very fast, thanks to some tricks we've learned from when we developed our Bluefruit Connect & Circuit Playground apps.
Trevor showed some of this off on the weekly Show and Tell too! - https://youtu.be/EmZWdpf2_XY?t=479

This week's EYE ON NPI is from long-time Maker-buddies FTDI Chip (https://www.digikey.com/en/product-highlight/f/ftdi/ft233hpq-usb-bridge): The FT233HP (https://www.digikey.com/en/products/detail/ftdi-future-technology-devices-international-ltd/FT232HPQ-REEL/13981010) and FT232HP (https://www.digikey.com/en/products/detail/ftdi-future-technology-devices-international-ltd/FT233HPQ-TRAY/13981013) builds on decades of work FTDI (https://www.digikey.com/en/supplier-centers/future-technology-devices-intl) have pioneered in making excellent quality USB controller ICs. This chip has taken the successful FT232H (https://www.digikey.com/en/products/detail/ftdi-future-technology-devices-international-ltd/FT232HQ-REEL/2614626) that we're very fond of and added first-class USB Type C support with PD3.0 control. (https://www.usb.org/usb-charger-pd)
Now in case you haven't tried them out yet, we make some nice FT232H breakouts here at Adafruit (https://www.adafruit.com/product/2264). This chip from FTDI is similar to their USB to serial converter chips (https://www.adafruit.com/product/284) but adds a 'multi-protocol synchronous serial engine' which allows it to speak many common protocols like SPI, I2C, serial UART, JTAG, and more! There's even a handful of digital GPIO pins that you can read and write to do things like flash LEDs, read switches or buttons, and more. The FT232H breakout is like adding a little swiss army knife for serial protocols to your computer! We recently even gave this chip a bit of a refresh by adding a Stemma QT port, an I2C mode switch, and a USB C port. However, that USB C port doesn't do anything fancy with USB C - it just has the bare-minimum resistors to let the upstream port know to give it 5V and use classic USB D+ and D- lines
The FT232HP, on the other hand, is a full new version of the chip with individual CC1/CC2 pins that are used to communicate with the upstream port to tell it what voltage level and current level desired. With PD, we can request up to 20V on the power pins (https://www.usb.org/usb-charger-pd) - and it can do this fully automagically by configuring an external EEPROM chip that is wired up on a PCB. You can program the EEPROM as many times as you like, using the FTDI Prog tool or via a command line tool (https://www.ftdichip.com/Support/Documents/AppNotes/AN_551_FT4232HP_FT2232HP_FT232HP_Configuration_Guide.pdf) Once configured you can also use GPIO pins to adjust the PD settings, or even use a built in I2C peripheral engine that can be configured by a separate microcontroller.
Besides the fancy new USB C power delivery control - the FT232HP and FT233HP also of course have the GPIO-control goodies we love about this series. The MPSSE peripheral set can mimic a wide variety of popular and useful protocols such UART RS232, RS422, RS485, 8-bit parallel, JTAG, SPI and I2C controllers. We've got Adafruit Blinka support for MPSSE (https://learn.adafruit.com/circuitpython-on-any-computer-with-ft232h) and while we haven't tested it with the FT232HP just yet, we're pretty sure it is going to be largely compatible (besides perhaps having a different USB PID).
If you're making a product that needs USB C PD, and maybe some GPIO control over USB - this chip could really do a great job at saving you months of development time. Particularly if you can use the MPSSE control software on a computer to avoid any firmware writing at all! Or, if you do have a microcontroller, you could get rid of half your power supply by dropping a DC jack input and going with a smart USB adapter with PD source control. The FT233HP has more pins than the '232HP and adds a USB Sink PD port as well as 8 more GPIO pins.
You can sign up to be notified when the FT233HP (https://www.digikey.com/en/products/detail/ftdi-future-technology-devices-international-ltd/FT232HPQ-REEL/13981010) and FT232HP (https://www.digikey.com/en/products/detail/ftdi-future-technology-devices-international-ltd/FT233HPQ-TRAY/13981013) arrive in stock at Digi-key today. Or, place on backorder now and it will ship in late June!

Adafruit has recently spent time adding support for the new Adafruit FunHouse WiFi Home Automation Development board to Wippersnapper, our no-code interface for Adafruit IO. We wanted to show off how easy it is to configure one of FunHouse's pushbuttons to act as a digital input and send data to Adafruit IO. All in under a minute!
What is Wippersnapper? Wippersnapper is a no-code IoT interface for Adafruit.IO - it lets you turn any WiFi-capable board into an IoT device without any programming. Simply select what devices are connected to which pins on the hardware and it will auto-configure the firmware and even create an IO feed for visualization

We've wanted to have something that plugs into a USB A port and provides a QT port for a while. But since we want it to support any and all QT boards, we need more RAM and storage than the SAMD21 can provide. We probably cannot buy any SAMD51's for like a year - but RP2040 is a good option! Lots of RAM and we stuck an 8MB flash on there. The idea is you can attach a QT sensor or whatever on top with some nylon standoffs, maybe it will even auto-detect which sensors are plugged in! We made the boot button a user-button too, thanks to a lil diode friend.

The Great Search is here to help you with the not-so-great parts shortage!
As we're doing more seesaw-powered boards, we want a very inexpensive, simple, but fully-inclusive microcontroller. It can be 32 or 8 bit, not too particular about the core chipset, but we need to have 3 to 5V power/logic, internal crystal/oscillator, built in FLASH and RAM (EEPROM would be nice too!), ADCs, GPIOs, timers, and all that stuff. And we want it to be cheap! But with big stock outages, our biggest priority is a chip we can get in under a year. Lets see what we find on The Great Search.

There's a new keeb boar in town, its the 3x4 macropad we've been working on for a bit. I finally got around to soldering it together, lets take a look at the features and press some buttons! We're also testing a fancy new PR that just got merged for CircuitPython - we can now selectively enable/disable USB descriptors: for example UART REPL or disk drive mode! It can be a little scary, so lets do it together. We also did some pretty pinouts for nRF52840 boards and we're going to tackle the SAMD21's next (the MUX spreadsheet is almost done)

Sparkfun came up with Qwiic and really changed how easy and fool-proof it is to use I2C sensor - and likewise we dig the new flex connector standard that DFRobot came up with for their displays. It has 18 pins so plenty for SPI, I2C, power, and a few extra GPIO. It's designed for displays so we're calling this EYE SPI! We hope it becomes a standard pinout way to connect SPI displays to microcontrollers! With rev B of this breakout, we even got the pinout right and ready for manufacturing.

This week's EYE ON NPI is a timely one - the Sensirion SCD4X (SCD40 and SCD41) a fantastic upgrade to the Sensirion SCD30 (https://www.digikey.com/en/products/detail/sensirion-ag/SCD30/8445334). Sensirion were clearly working on this sensor for a few years, but got some excellent timing as they finished and released it right when demand for CO2 sensors skyrocketed.
Carbon dioxide, aka CO2, is a gas that is an essential part of the Earth's atmosphere and life in general. However, while essential, it can have negative effects when concentrations exceed certain levels. It can impact the entire planet via global warming. But it can also have very local effects, for example on indoor air quality. Elevated levels of CO2 can lead to reduced cognitive ability and other health related concerns. Therefore, monitoring CO2 levels of inside air can be useful as a part of gauging general air quality.
Folks have had CO2 air-quality sensors in buildings and homes for a long time, but now they're extremely popular because CO2 levels are correlated with air freshness. Outdoor air is about 400 ppm CO2. Us humans love to breathe in air, extract the O2 and fill rooms with CO2. That means when there's poor ventilation to the outdoors, and lots of humans, the air is going to get higher and higher CO2. (https://theconversation.com/how-to-use-ventilation-and-air-filtration-to-prevent-the-spread-of-coronavirus-indoors-143732) We consider under 1000 ppm to be 'good' but really we want to keep it under 600 ppm if we can since that has been shown to reduce transmission of airborne disease (https://onlinelibrary.wiley.com/doi/full/10.1111/ina.12639)
First, let's talk about the SCD-30, since this the next generation sensor. The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means it's a lot bigger and more expensive than eCO2 sensors, but it is the real thing. Perfect for environmental sensing, scientific experiments, air quality and ventilation studies, and more. However, its...kinda chunky and requires hand-soldering.
Thus the awesome introduction of the SCD4X series which comes in four part numbers: SCD-D-R1 (https://www.digikey.com/en/products/detail/sensirion-ag/SCD40-D-R1/13684001), SCD-D-R2 (https://www.digikey.com/en/products/detail/sensirion-ag/SCD40-D-R2/13684003), SCD41-D-R1 (https://www.digikey.com/en/products/detail/sensirion-ag/SCD41-D-R1/13684000) and SCD41-D-R2 (https://www.digikey.com/en/products/detail/sensirion-ag/SCD41-D-R2/13684005). The SCD40 and SCD41 differ in price and precision. SCD40 is base accuracy, with a specified range of 400 to 2000 ppm for continuous measurements, good for vast majority of indoor measurements. SCD41 is high accuracy, specified range 400 to 5,000 ppm, with both continuous and single shot mode supported: perhaps better for scientific or industrial or low-power use cases. Both have the same instructions and footprint so you could swap them easily on the PCBs.
It was really easy for us to get an Arduino demo going with the SCD4x because Sensirion has written drivers for Arduino, Raspberry Pi, Python and even MakeCode! (https://github.com/Sensirion/?q=scd4&type=&language=&sort=) Add to that, there's a cute breakout board with JST-PH connector and breakout pads so you can quickly wire it up and get data into your favorite platform. (https://www.digikey.com/en/products/detail/sensirion-ag/SEK-SCD41-SENSOR/13684004?s=N4IgTCBcDaIM4GMAmAWEBdAvkA) The sensor can run from 3 to 5V but we've noted that it needs very low ripple - so use the quietest power supply you have access to. With built-in humidity and temperature sensing as well, it's an all-in-one air measurement sensor about the size of a skittle.
You can pick up SCD40 and SCD41 sensors at Digi-Key. (https://www.digikey.com/en/products/filter/gas-sensors/530?s=N4IgTCBcDaIMoGEAiAWEBdAvkA) Note that at this moment they're out of stock, but they will be restocked in a few weeks so sign up to be notified or place on backorder. There are breakout boards available now (https://www.digikey.com/en/products/detail/sensirion-ag/SEK-SCD41-SENSOR/13684004?s=N4IgTCBcDaIM4GMAmAWEBdAvkA) - order today so you can start sensing tomorrow!

Let's put together some breakout boards. This is a breakout for a round-rect 1.69" TFT. It's not the best time to be working on TFTs, given the shortage, but we wanted to wrap this one up anyways. We can use our little hot plate even though the PCB is larger, when we get to peak temp we just sorta move it around to get even-er heat.

The great search is here to help you with your not-so-great parts shortage!
This week we're looking at a twitter thread of folks commiserating over AWOL components.
Tobias is frustrated to see a 30 cent part, the TPS27081A (https://www.digikey.com/en/products/detail/texas-instruments/TPS27081ADDCR/3671584?s=N4IgTCBcDaICoAUDKYDsAGAHARgIIAIQBdAXyA) go for $15 from unscrupulous brokers! (https://twitter.com/Dg3Yev/status/1391155677675073538)
Maybe we can find some pin-compatible alternatives for them? Let's go on the great search!

These rotary encoder user-interface elements remind us a lot of very old iPods (before it was all touch wheel interface). The middle wheel is a rotary encoder, and there's 5 buttons in addition (up down left right and center). We made a breakout to test the footprint and whipped up a little demo - the Feather reads the buttons and encoder and light up the attached NeoPixel ring to match. So far so good!

A lot of folks like using Adafruit parts for their Keeb builds - but with the itsybitsy not being pin-compatible with the pro micro pinout, it really wasnt very easy without some sort of adapter plate. now we're seeing lots of people use circuitpython for keebs, which is awesome! why not try our hands at spinning up a pro-micro-compatible RP2040 board? the RP2040 is plenty powerful, low cost and makes for an excellent keeb driver chip. we tried to mix together the things we liked most about the sparkfun pro micro rp2040 (Qwiic/QT I2C port on the end, so good!) the Elite-C (castellated pads & pins for D+ and D-!) and our existing 2040 boards (boot button can be used for user, 8MB QSPI flash, onboard NeoPixel, jumper for skipping the diode/fuse for high power RGB LEDs or USB hosting). we even got it to all fit on a 2 layer PCB with 7/7 routing - just needed to make the smallest caps and resistors 0402. ground plane didnt suffer too much either - take a look! (hat tip to JLCPCB who fixed up their gerber render to manage castellated pads)

We did a bunch of lil things this week, let's check them out: We designed a Kee Boar with the RP2040, based on the Pro Micro pinout but with some cute extras. Our snap-apart ortho keeb breakout PCBs arrived, as did our RP2040 macro-pad PCBs. We also tested our Zippy click-wheel breakout and are looking for a replacement chip for seesaw (that we can get in stock!)

Open source stories - Supporting MicroPython - ASK AN ENGINEER clip
https://blog.adafruit.com/2021/04/29/happy-8th-birthday-micropython-micropython-micropython-and-adafruit-sponsoring-join-in/
We celebrated MicroPython’s previous birthdays, last year in NYC we were dealing with shutdowns, death, sickness, and more – so we did not get a chance to do a post. But with a new year and 2021 going in the right direction, we are making some noise about the 8th birthday in all the ways we can!
Happy Birthday! We have stocked the official PyBoards from Damien, made direct donations to Micropython to support Damien’s work, make and share contributions, based on CircuitPython core on MicroPython and NOW with GitHub sponsors, we did a $5k sponsorship. Their goal is $5k a month in sponsors, so 1 full month is on us. We hope other companies and orgs that use MicroPython will consider doing a monthly or one-time as well. Companies / orgs can now sponsor, so this was Adafruit sponsoring.

We just wrapped up the NeoKey Trinkey tester, which uses a Teensy to program the SAMD21 processor and then test the USB interface. It's a simple USB A pluggy-board with a cherry MX-compatible footprint (can use Kailh, Gateron etc!) with underlit NeoPixel and one capacitive touch pad. Simple and fun, its your new best friend! Great for adding ESC keys to old macbooks.

This week's EYE on NPI is one I've personally got an EYE on for a few months: the TI BQ25792 I2C Controlled, 1-4 Cell, 5-A Buck-Boost Battery Charger. This luxurious charger caught my eye a few months ago and now it's available for purchase and I'm really excited about it. This chip does everything you could ever want from a battery charger. We showed off a charger chip last week that was designed specifically for ultra-low current and voltages - great for TEC's or small solar cells. But what if you want HUGE charging capabilities? The TI BQ25792 has you covered, no matter your application.
First great thing - support for any size battery. We have lots of battery packs in the Adafruit shop, and in particular we use 1S batteries - if there's more batteries they are wired in series. But there's lot of folks who are building robotics that require higher voltages, so they have 2S, 3S, or 4S batteries. This charger can handle any of em, and you can configure the battery pack size using a simple resistor on the PROG port.
Second great thing - support for just about any voltage power supply input. Once you set the battery size, the output charging voltage has to be 4.2V-per-cell. Normally that means that if you're charging a 1S battery, you'd want a 5V power supply (4.2V plus some headroom). For 2S you want 9V to 12V, etc. Sometimes you'll see buck or boost chargers that let you have a lower or higher voltage. This chip is a buck-boost so you can have anything from 3.6V to 25V input and it will do the right thing to get you the voltage you need to charge the battery pack you have. There's some efficiency-loss on conversion, but much less than a linear supply and you don't have to worry about needing the exact-right power adapter or USB power supply. (https://e2e.ti.com/blogs_/b/powerhouse/posts/universal-and-fast-charging-a-future-trend-for-battery-powered-applications)
OK we've done the output, we've done the input. Now lets look at the creamy middle:
This charger has our favorite TI-capability: VINDPM and IINDPM - the ability to track the input voltage to make sure it is not drooping from over-draw. Say you have a battery, you want to charge it at 2A, but the wall adapter maxes out at 1A - you don't want the voltage to collapse on you, it's better to charge slowly at 1A than not at all at 2A. VINDPM/IINDPM auto-monitors the voltage and if it starts dropping, it will reduce the current draw. There's also ICO, which attempts to find the max-power-point for the power adapter, which may not be the exact same thing since there's different buck-boost efficiencies at different voltages.
For when you're using USB for power, the charger can auto-detect the 'Apple-style' resistors used to set the max-draw current available. (In theory, we acknowledge it's probably better to just VINDPM/IINDPM when possible but we figure it's also polite to stick to the max-current-draw set by the chargers.
Finally, there is an "OTG" mode where the converter 'turns around' and can be a buck-boost that runs off the battery to charge another device. Really a wonderful chip with a lot of capabilities and looks like no matter what it is you're trying to charge or power! I'm ordering some BQ25792 today for a new design I'm working on. From the looks of this datasheet, TI really stepped it up here (pun intended!) to make a battery charger everyone will love. Check out TI's video for a lot more details (https://www.youtube.com/watch?v=Wjk5YWrt8Ww)
The BQ25792 is stock right now, for immediate shipment from Digi-Key (https://www.digikey.com/en/products/detail/texas-instruments/BQ25792RQMR/13577777)

This new upcoming board is a I2C-compatible Rotary Encoder, and is powered with a SAMD09 processor running the seesaw firmware https://github.com/adafruit/seesaw To program it we use another SAMD board, this time a Metro M0, to run SWD DAP code https://github.com/adafruit/Adafruit_DAP that programs the chip and then runs the I2C test. We know it works when the NeoPixel goes rainbow!

We noticed a few synth-makers getting worried about not being about to source TL074 quad op-amps! https://twitter.com/theavalkyrie/status/1381800012162666497 https://twitter.com/otdispace/status/1382920010042081283
We thought we'd spend this Great Search looking at the TL074 - why its so great and what to look for in an alternative. We asked 'guest' - the co-designer of the x0xb0x to drop some knowledge on us:
the 074 is pretty much the toyota corolla of opamps. its not the best at anything in particular, but pretty good at everything. its the second cheapest opamp out there, comes in dip and soic, has relatively low current consumption, low distortion, and reasonable bandwidth and slew rate. the noise is ok-ish low, but the thing that really makes it an all around performer is the low bias current. its down in the pA range, which means you can use it for S/H or VCO,VCF, etc that require a range of currents down to the nAs. a lot of people used the LM358 because it is the cheapest opamp, but it has high bias current. the 074 can also handle high voltage rails which helps with SNR. it was designed for audio use, and was one of the first real mass market opamps back in the late 70s (if i recall correctly). the 741 was the first, and this was meant as an improvement over that. the 074 and 084 were made at the same time, and 074s were selected for lower noise, better distortion, and lower offset voltage, and then marketed at the audio market. the 084 was sold to everyone else.
Who doesn't love the TL074? Apparently a lot of people - so let's look at a backup-option. It may not be as cheap/good but maybe it'll be in stock!

This week's Desk of Ladyada is a little light on hardware, as we spent some of the weekend outside and the rest on some software hacking! We used to get very nice pinout diagrams made for our boards by a fellow named Pighixxx. They ended up doing a crowdfunding project that didn't work out and they stopped replying to emails. We like having pinout diagrams but also know that if it's too hard, we won't keep up. Check out Bill Binko's video for a manual technique https://blog.adafruit.com/2019/07/11/automating-the-making-of-beautiful-pinout-diagrams-for-microcontroller-boards-documentation-at_makers/
Much like our Fritzing tool which can generate 99%-ready fritzing objects, having an automated way is best! We looked at the Sparkfun Graphical Datasheet tool (https://github.com/sparkfun/Graphical_Datasheets) and its a step in the right direction - but we didn't want to have to create a CSV for each board because I am very lazy!
So we're experimenting with using the Fritzing file, circuitpython pin file, and a single chip-pinout spreadsheet to help us get something 'good enough' even if it isn't as beautiful as the Pighixxx ones. I'll talk about some of the tools we ended up using and why we still need a human to wrap it up.
We also made the first draft of an RP2040-powered 3x4 macro pad with rotary encoder and OLED that we'll show off.

Did you know the SAMD51 has a PCC (parallel capture) peripheral, for reading in camera/video data? that's right, you can directly wire up OV7670/OV2640-like cameras to a SAMD51 and then read out image data into a RAM buffer. We just got support into CircuitPython as well, so we can read a buffer, as seen here, then pipe it back out over SPI to a TFT. Could be great for image recognition, tinyML, DIY cameras, IoT monitoring, etc! The camera almost-perfectly plugs into a Grand Central, you have to cut the two pins for 3V/GND and rewire them, as well as adding I2C pullups. Check out the library here https://github.com/adafruit/Adafruit_CircuitPython_OV7670

Did you know the RP2040 PIO periperals can be configured for reading in camera/video data? that's right, you can directly wire up OV7670/OV2640-like cameras to a RP2040/Pico and then read out image data into a RAM buffer (thankfully theres a ton of RAM on the RP2040). We just got support into CircuitPython as well, so we can read a buffer, as seen here, then pipe it back out over SPI to a TFT. Could be great for image recognition, tinyML, DIY cameras, IoT monitoring, etc! We built up a Perma-Proto for swapping different cameras in for testing. We're getting a little posterization-effect, which looks cool but is not on purpose, hopefully will get it sorted out very soon!

This week's EYE ON NPI smells so sweet, it's the BME688 digital nose gas sensor from Bosch! (https://www.digikey.com/en/product-highlight/b/bosch-sensortec/bme688-4-in-1-environmental-sensing) The BME680 is a very nice gas sensor released a few years ago, and remains the only temperature-humidity-pressure-gas sensors that we've ever seen. Small and easy to use, at Adafruit we've sold tens of thousands of BME680 sensors on breakout boards so we're very excited to see the next-generation of BME68x chips arriving and in stock at Digi-Key.
The BME688 is completely back compatible to the BME680, in fact over the weekend we added support to the latest Bosch C API (https://github.com/adafruit/Adafruit_BME680) So, like the BME680 you get a high-grade temperature, humidity and pressure sensor that can measure humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter or better accuracy!
I'm going to order some ASAP to turn into a breakout board, it looks like this chip is fully pin-compatible with the BME680 so if you need an example circuit that we know works, check out our open source BME680 design. (https://github.com/adafruit/Adafruit-BME680-PCB) If you're looking for a great all-in-one sensor, and particularly if you've been using the BME680 and want to upgrade, there's thousands of BME688 stock at Digi-Key right now at a great price! (https://www.digikey.com/short/0vjw0b8q) Order today and you will be smelling success by tomorrow afternoon.

Full tutorial: https://learn.adafruit.com/sound-reactive-sunflower-baby-crib-mobile-with-bluetooth-control
Make a beautiful hanging mobile with lights for your nursery. This mobile is so cute and so much fun that older kids and adults will definitely enjoy it as well.
The included sample code has around 8 different animated color modes that you can control via bluetooth using Adafruit's free BlueFruit app. It also has a sound reactive mode, where the lights will pulse in time to music or voices in the room.
This is a fairly easy build that requires just a little bit of tight soldering on the LED strip. The sunflowers are made from craft foam and felt that you can cut by hand or with a vinyl cutting machine. This project uses just a half-meter of very high density NeoPixels, making for gorgeously buttery smooth animations.

This Expansion board is designed for the Seeed Xiao, and since the QT Py is pin compatible we thought we'd try it out with the RP2040 QT Py we just released to see how it works with CircuitPython. The RP2040 has toooons more flash and RAM than the SAMD21 so it's a great little add-on! There's a 128x64 OLED, button, piezo beeper, battery charger and booster, SD card and RTC. We were able to get everything going thanks to pin-compatible hardware!

Compare that to our Power Relay Wing, which can do an impressive 1200 Watts! https://www.adafruit.com/product/3191 Why would we make a latching version, what's single/double winding?

We had a few PR's go into CircuitPython this week to add digital camera support to platforms with parallel-capture support. We started with SAMD51 and also added RP2040 thanks to some clever PIO work. PaintYourDragon and Jepler teamed up to one-two-punch Arduino and CircuitPy support at once, starting with with classic OV7670 cameras and then moving onto the OV2640's next. This could be great for simple vision/TinyML projects. We also added "Pico-as-hardware-peripheral-for-Blinka" support thanks to u2if https://github.com/adafruit/Adafruit_Blinka/pull/449 which works very nicely and at a price one can't beat!

Adafruiter Carter recently did a PR for adding Blinka support to the U2IF for RP2040 project.
According to the developer, "u2if (USB to interfaces) is an attempt to implement some of the MicroPython "machine" module functionalities on a computer. The goal is to be able to communicate with breakout boards (sensors, lcd...) simply from a python program on x86 machine. It uses a Raspberry PICO microcontroller to make the interface between the computer (USB) and peripherals/protocols."
Hey that sounds a lot like Blinka, our compatibility layer for adding CircuitPython library support to CPython. With some quick coding, Carter pulled together some code to test it out! and here we're testing ADC (potentiometer input), PWM (LED output), I2C (VL53L0X) and SPI (DotStar LEDs). Of course everyday GPIO also works so you can control relays and buttons. What a great use of a $4 microcontroller, now programmable with CPython to control all sorts of hardware thanks to Blinka and our 300 CircuitPython libraries. Check out the PR here https://github.com/adafruit/Adafruit_Blinka/pull/449

Wippersnapper is our no-code IoT interface for Adafruit.IO - it lets you turn any WiFi-capable board into an IoT device without any programming - simply select what devices are connected to which pins on the hardware and it will auto-configure the firmware and even create a IO feed you can then log and/or use to control other devices by triggering events or webhooks. We recently added analog inputs, and wanted to show off how it works with selecting an element (potentiometer) and the attached analog input pin, to getting it in as an MQTT feed...all in just about 1 minute!

(does that make sense) 39:30 v1.10 40:16 CP translation considerations ( new strings?) 42:30 MP (native/machine code) emitters 43:22 thought CircuitPython already supported underscores in numeric literals.

One channel of a timer ? 58:20 v1.13 1:06:39 Was there a time where people were saying that using foo and bar make IT less accessible and it is not good for STEM and being open? Is that still the opinion? 1:07:03 With threading an interrupts couldn't we just write them in a c code block to use that inside circuit python? 1:09:12 v1.14 1:12:00 Could you rename the cp Ports folder do eliminate all these naming conflicts ? 1:15:20 v1.15 1:22:07 v1.11 merge failing checks… 1:24:20 git worktree 1:26:23 Is there a specific CPython version that you target compatibility with? (2.7, 3.9, etc) 1:27:45 fixing atmel-samd build error (openbook_m4) 1:35:04 Git commit --amend and cherry picking… 1:37:00 Are you getting the diff between MP's v1.x and v1.(x+1), and then cherry-picking that? 1:38:25 So how are you bringing in the per-release changes from MP? 1:40:55 Scott’s ‘other project’ / use git to store laws / HB1336 - 2021-22 1:52:40 Uniform Electronic Legal Access 1:53:55 RCW (current state) 1:55:00 wa-log.org 1:56:50 adoc (asciidoc) vs markdown 2:04:56 Gitlab allows adding users 2:11:06 Bills and terms of service agreements are things I wish I could track history of it better 2:11:30 completely different question from the topic. why adafruit nrf52840 still using softdevice 6.1.1 stack instead of 7.2.0(because of different memory layout)? 2:14:12 (4:10pm) wrap up 2:15:30 - headset off (4:12 pm)

The every-day male header pins, they come in so handy! They make great board-to-board connectors, with good current carrying capacity, fair durability, low cost, and near-infinite configurations. Lets practice how to find them on Digi-Key since there are thousands to choose from. We'll give tips and tricks on cost-vs-premium, Marketplace products, and Value Add services.

What's better for your project than rings, strips, boards and sticks of pulsing, colorful miniature LEDs? We can't think of much else - and that's why we carry a complete line of the Adafruit original NeoPixels.
These popular products are chainable from one to the next so you can power and program a long line of NeoPixels together to form an endless (or almost endless) string of 5050 LEDs. Plus, with our NeoPixel Uberguide, wonderfully written NeoPixel library for Arduino and our diverse range of Learn System projects, its never been easier to both find a project and program it to glow or spin or flash as quickly, slowly, and vibrantly as you want.

It's a Keeb-ful sunday at the Desk of Ladyada - we launched the NeoKey breakout and dual key FeatherWing. But what about folks who want MORE KEEB? We chatted last weekend about making some sort of macro-pad or configurable keyboard, ideally with snap apart bits. Today we spent some time making the custom footprint that would let me easily tile Kailh-socket-plus-NeoPixel objects. There was some concern about how to handle snapping from various sides till an 'a-ha!' moment. Also, we're going to mint our first “NFT” (we are not), come by to see what it's gonna be.

This week's EYE ON NPI has frickin' ceramics with frickin' lasers on its head - it's a Wurth Elektronik Vertical-cavity surface-emitting laser (VCSEL) infrared laser emitter (https://www.digikey.com/en/product-highlight/w/wurth-electronics/wl-vcsl-vertical-cavity-surface-laser) . These pick-and-placeable components look a little like large LEDs, and they sort-of are. Except unlike LEDs, the light wavelength is very narrow band wavelength AND it is 'coherent' light (https://en.wikipedia.org/wiki/Coherence_(physics)) which means that the emitted waves of light are all in sync.

Ooh we're fabbing QT Py RP2040 https://www.adafruit.com/product/4900 as fast as possible, folks love these adorable boards. With an RP2040 chip plus 8MB flash plus QT connector plus NeoPixel and two buttons...what is not to love? We want to get these tested as fast as possible, so we're using the Teensy 3.6 as a mass storage host, it 'drag's the UF2 over to the drive which then performs the self test. Voila, 2 seconds later we have the Neo glowin' and the board is ready to ship out.

We're drunk on Trinkey's here - we tested our four pending designs: slide trinkey, neokey trinkey, rotary trinkey and prox/light trinkey. All working well, we made Arduino and CircuitPython definitions for all four, and wrote a little example code. We also got a funky rotary encoder sample, a Kano Motion Sensor unboxing/teardown and a preview of BUNDLE FLY - the new CircuitPython library manager built into the adafruit learning system! We also started thinking about a Trinkey for connecting any I2C sensor, maybe a QT Trinkey...which we're going a slightly different direction with.
The Great Search - Nylon PCB Spacers https://www.digikey.com/short/3vwj40b0
For our new QT Trinkey design we want to have QT sensors snap on with little plastic standoffs that have nubbins in them. What are these called? What sort of types are available and how do you buy them on Digi-Key? We'll go on a quest to get the perfect standoffs for our modular system!

What's better than one rotary encoder? FOUR of them! but who wants to deal with that much code...when you can use seesaw instead? this samd09 firmware will read 4 encoders plus switches, and keep track of all the grey code transitions. it can even light up 4 neopixels - all over I2C for easy use with any microcontroller or microcomputer.

Rotary encoders are fun but a real pain to implement, especially if you don't have a real time OS. This seesaw-powered board give you a rotary encoder with I2C interface, the lil Cortex M0 is cheap and powerful enough to handle the gray code toggle counting, and then pass back the value to the I2C controller whenever requested. You can chain a bunch together on one bus for lotsa twisting fun. We're going to add a NeoPixel and then fabricate! Firmware is here https://github.com/adafruit/seesaw

For this week's EYE ON NPI we're going to put a bug in your ear, with the Knowles IA611 SmartMic Audio Processor (https://www.digikey.com/en/product-highlight/k/knowles/ia611-smartmic-processor-xplained-pro-dev-kit) - perfect for making intelligent headsets, earpods or other low-power microphone devices. We've covered plenty of microphones before, including MEMS mics, and they've always been pretty straight forward: audio waves are detected, converted to a voltage, then piped out over PDM, I2S or analog. This microphone is particularly nifty, it can output I2S or PDM but it also has a built-in DSP processor that can detect keywords even in ultra-low sleep modes. This chip is specifically designed for making smart earpods, but would do well in any battery-powered product that needs voice activation

Last week we took a peek at Rotary Encoders available at Digi-Key. This week we're going to try to find a similar-footprint rotary potentiometer. When would you want a pot vs an encoder? What is a rheostat? What are some nifty options you can get when ordering? What about knobs? We'll go digging for the potentiometer that best fits our project and share some tips as well.

We're finally getting back to some really old seesaw projects. Seesaw is our "i2c to anything" protocol/chip firmware. Turn a 50 cent chip into an I2C to NeoPixel/GPIO/ADC/DAC/Captouch/Encoder/etc converter. This breakout will let us read rotary encoders, notoriously annoying to use, into an easy I2C peripheral! These boards are 1" x 1" so they can be easily reflowed with an adorable mini hot plate https://www.adafruit.com/product/4948

Music by Bartlebeats https://soundcloud.com/adafruit
We're on a bit of a tear, playing with mechanical interface elements like mechanical keyswitches and now rotary encoders. This week we finished our 4-key I2C breakout, we had a yucky edge-case condition in our firmware where an GPIO IRQ could come in while we were handling one already, which caused a lockup. We also finished a very old project to make an I2C rotary encoder, while we were in the seesaw code we extended the code to support up to 16 encoders on arbitrary pins, we're planning on making a 4-encoder I2C breakout with NeoPixels. We also got our prototypes back for some more trinkeys! We're also thinking of making a 4-potentiometer seesaw board.
The Great Search - Rotary Potentiometer https://www.digikey.com/short/22hmzq3b
Last week we took a peek at Rotary Encoders available at Digi-Key. This week we're going to try to find a similar-footprint rotary potentiometer. When would you want a pot vs an encoder? What is a rheostat? What are some nifty options you can get when ordering? What about knobs? We'll go digging for the potentiometer that best fits our project and share some tips as well.

Today I'll answer questions and discuss the work to get a BLE workflow going in CircuitPython.
I’m sponsored by Adafruit to work on CircuitPython. Support them, and by extension me, by purchasing hardware from https://adafruit.com Chat with me and lot of others on the Adafruit Discord at https://adafru.it/discord.
Deep Dive happens every week. Normally Fridays at 2pm Pacific but occasionally shifted to Thursday at 2pm. Typically goes for two hours or more. Questions are welcome. Next week will be on Friday and will be the 1 year anniversary!
0:00 Getting started after technical difficulties 4:04 hello and thanks to 009 for the gpu clue 7:04 q: just started my first BLE project that i showed on S&T. i'm confused what the BLE components i need to setup some kind of "clear/reset connections and repair from scratch" button to make my board useable across devices without having to manually disconnect before reconnecting 9:19 core modules ble erase_bonding… 9:59 working on a digital thermometer for an old bmw that would obviously show the engine's temp. I want to use an stm32. 15:04 BLE - Bluetooth Low Energy 17:51 Circuit Playground Bluefruit - Bluetooth Low Energy 20:14 what applications would you recommend BLE for? 25:49 Bonding 29:45 I know you can SEND data with the Micro:bit BLE, but can you program it from mobile through BLE?? 30:14 Serial/UART over BLE is not "super standard" as opposed to Serial on Bluetooth. There is a circuit python LIB that does the Nordic way. But you cannot change the UUID for another copy of serial. 30:49 BLE workflow - discovery 35:59 for devices that allow multiple devices to connect (like a mouse that toggles between machines) do you need a separate BLE chip for each device? 37:04 Is this workflow tied to BLE or is it standard for regular (older) bluetooth as well? 37:24 The number of pairs, bonds, or connected? 40:19 I want to make a BLE keyboard that I can quickly switch between my phone, desktop, laptop, and RPi. So, what's the most bonds possible? 42:14 what security things should be we aware of when working w/ BLE? 46:24 Desktop / “where scott is at”... 46:54 Packet buffer fixes #4535 48:34 Don't the packets have sequence numbers? 49:21 Fix central pairing #4522 51:45 Proof of concept code for CP future behavior 52:28 I noticed a 7.0.0 tag has appeared in the CPY repo. wonder what that will bring 54:09 So it is not going to be in the "kernel" but in "library"? Or it is a mockup in "userland"? 54:39 Adafruit_CircuitPython_BLE_Creation / Creation IDs on github
58:04 instance id? ( NO ) 1:02:48 Creator IDs, how are you allocating them? So 0x1234_xxxx could be registered by one person/organisation? 1:03:56 Examples ( advertisement / scan? ) 1:05:04 File Transfer 1:06:54 The BLE SIG is in Kirkland, WA if you want to chat with them. I might have some contacts. 1:07:09 There is/was that file transfer solution over the REPL for micropython. Can you reuse that? 1:07:55 Do you envision the BLE file transfer protocol requiring the storage to be mounted writable from boot.py on the CircuitPython device? 1:09:54 ampy == That was the recommendation for micropython… ( “No - don’t like it”) 1:10:14 This might be old information... but at one point iOS didn't support serial over bluetooth. (Ham radio control apps used this). Has that changed ? 1:11:04 What is BLE range on CPB/Micro:bit (estimate) 1:12:29 Does BLE keyboard use scan codes or ASCII? ( Same as USB ) 1:13:46 BLE file transfer library 1:14:34 BLE number set 1:17:34 I'm going to need a way for my keyboard to know whether the device it's talking to is in Dvorak or US mode. 1:20:09 Flow Control 1:21:49 demo 1:23:09 In "Bluefruit Connect" you have packet based protocol, over serial with function like picking a color or sending image... you could expand that. 1:24:53 Is the bug that it's starting to corrupt the file system, but not finishing the job? Or that it's corrupting the filesystem at all? 1:25:19 Maybe that "Bluefruit Connect" and protocol and serial was there for old way to connect serial co-pro to old stuff, before nRF52 support. 1:25:55 - Demo …( using tio on arch linux ) 1:28:59 - Ryzen 16-core - speedier than a raspberry pi 4 1:31:39 - simulating the file system in a dictionary 1:33:32 book recommendations for ble ? 1:35:01 Blinka "server side" thing, to control a PiZero? Is that possible or we hit a limitation of BLE on the Blinka side? ( To have the BLE workflow for a Pi. ) 1:35:36 https://www.amazon.com/Make-Bluetooth-Projects-Raspberry-Smartphones/dp/1457187094 for Sander Vesik's question. 1:38:41 Any news about the "convergence" with BLE on micropython? /Both MP and CP were developing separately at the same time. / Low level, so blinka can build on top... to make it CP like. 1:45:34 outline for OHS 1:48:23 Soooo at 15 minutes is it a shallow dive ? 1:48:49 plan for next weeks - don’t block Trevor 1:50:12 wrap up

Build a neon stick-person costume from LED neon strips. These strips glow really brightly when connected to power, without the need for additional controllers or code of any kind. Just solder them together, plug in your battery pack, and glow!
They come in a lot of different colors, so you can glow in style. Make one for everyone in your family for an unforgettable group costume next Halloween.
This tutorial will show you how to connect the strips together and power them, and make a simple velcro harness that straps on over your dark clothing to bring the costume to life. It's easy to adjust to fit different sized people, and no sewing is required.
Suit up and let the dancing commence.

Much like the post-recession months after 2008, we're in the midst of a bit of a component squeeze. Chances are you've been warned by your suppliers that many parts are in short supply, and lead times have stretched into the many-months or even a year! Here at The Great Search we feel ya, we've seen many components evaporate. Parts that were discontinued-but-still-available are now 'really really discontinued' But no worries, with a little search-skills we're often able to find replacements. So it's no surprise we'll be doing a few 'alternative' search shows! This week we're going on the hunt for a replacement to the APX803-26SAG, our favorite auto-reset supervisor - a little chip that has helped countless designs wake up cleanly.

It was Arduino Day yesterday, check out Arduino's YouTube channel for recorded streams. We tried out an Arduino board support package for the RP2040/Pico with success! We got the Feather RP2040 and our QT Py both up and running with some demos. NeoKey designs are starting to make it into the shop. We sketched up a possible new Trinkey design and a breakout for a fancy new CO2 sensor. On the QT front, we're going back and QTifying some older designs still. This week we redid our old 7-segment breakouts - ancient stuff! We also spent a lot of time snagging components so we can keep in production for the next 6 months plus. The Great Search - Replacement for APX803 Auto-Reset Supervisor https://www.digikey.com/short/r07ph903 Much like the post-recession months after 2008, we're in the midst of a bit of a component squeeze. Chances are you've been warned by your suppliers that many parts are in short supply, and lead times have stretched into the many-months or even a year! Here at The Great Search we feel ya, we've seen many components evaporate. Parts that were discontinued-but-still-available are now 'really really discontinued' But no worries, with a little search-skills we're often able to find replacements. So it's no surprise we'll be doing a few 'alternative' search shows! This week we're going on the hunt for a replacement to the APX803-26SAG, our favorite auto-reset supervisor - a little chip that has helped countless designs wake up cleanly. It's no longer available, will we be able to find a drop-in replacement? Tune in to find out!

We're playing around, testing things on the upcoming Metro M7 https://www.adafruit.com/product/4950. This time we're doing a TFT shield demo to test out displayio and our ILI9341 driver. We made a fun bouncing DVD demo with transparent pixels. Our code allows a dynamic number of DVD logos for bouncing pleasure. Mostly this is us seeing how a 500 MHz processor feels with CircuitPython! Still lots to do, but this code is working pretty well, no crashing.

We tried out our Feather RP2040 with this early Arduino core for the Pi RP2040/Pico https://github.com/earlephilhower/arduino-pico and that worked out so we wanted to then try out our upcoming QT Py 2040 https://www.adafruit.com/product/4900 as well. We plugged in our OLED with Stemma QT, and then popped a temperature sensor on the end. After configuring the I2C pins, it worked great. We can't wait for the official Arduino core, it's going to be so much fun!

We saw this nifty Arduino core for the Raspberry Pi Pico / RP2040, developed by earlephilhower https://github.com/earlephilhower/arduino-pico and decided to take it for a spin! It's early, and there's a few caveats but it works! Here's our test of I2C with a temperature sensor and SPI with a TFT display. USB Serial also works. Pretty neat stuff, this is just us trying it out while we wait for the official Arduino core for the RP2040.

These low cost "Black Pill" STM32F411 boards are a lovely upgrade to the STM32F401. With 512KB of flash and 128KB of RAM, this board has lots of GPIO for projects. And now you can use it without a toolchain or IDE setup - all by installing CircuitPython! Here we loaded the CircuitPython build on with STM32Cube and with a few lines of code have an OLED screen showing the REPL.

See this product on Digi-Key at https://www.digikey.com/short/rn8rw873
This week's EYE ON NPI is keeping things easy, with an innovative new approach to flex connectors: introducing the One-Touch series of push-button FPC connectors from Molex! (https://www.digikey.com/en/product-highlight/m/molex/one-touch-ffc-fpc-easy-on-connectors) Molex's connectors have a visible release button that allows for easy release operation. An innovation that will keep assembly and maintenance of flex connectors safe and easy.
We use flex cables a lot in our electronic design. (https://www.adafruit.com/?q=fpc&sort=BestMatch) They are inexpensive, slim, durable, and easy to use. The connectors are likewise, inexpensive and un-intrusive. If you want to pass 20 to 50 (ish) contacts from one place to another, an FPC is going to be the way to go, no crimping, no housings, all pick & place friendly. Nearly all of our displays use flex connectors on em, which means the boards we have on the other side have an FPC connector. We tend to use either 'push/pull' connectors, these tend to have top-contacts.
(https://www.digikey.com/en/products/detail/molex/0541324062/24047840)
Or we use flip-top connectors, these tend to have the contacts on the bottom.
(https://www.digikey.com/en/products/detail/molex/0512964094/3044821)
These work great... almost all of the time. But once in a while, the little ears on the side of the connector come loose. Or sometimes they break off! And if the little insert breaks at one of the small hinge pieces, the whole connector needs to be replaced. And these connectors are really annoying to rework. Sometimes we just scrap the whole board because its so difficult to repair.
That's why we really liked the look of the One-Touch FPC connectors from Molex (https://www.digikey.com/en/product-highlight/m/molex/one-touch-ffc-fpc-easy-on-connectors) when we saw them pop up on the Digi-Key new products page (https://www.digikey.com/en/new-products). No yanking, twisting or pulling. They work just like other FPC connectors you're used to, with similar footprints and both right-angle (https://www.digikey.com/en/products/detail/molex/2004850440/13588615) and vertical style available. (https://www.digikey.com/en/products/detail/molex/2004850540/13588607) FPC's can be inserted and will auto-lock in place. To remove, press on the button and remove the FPC. They are rated for 20 insertion and removal cycles, which should let the board make it through quite a few maintenance/rework/repair cycles!
The Molex One-Touch FPC connectors are available in a few of the most popular sizes from 10 to 40 pins, in 0.5mm pitch (https://www.digikey.com/en/product-highlight/m/molex/one-touch-ffc-fpc-easy-on-connectors) and will make a very nice upgrade for your next product design where you've seen a history of broken or damaged FPC connectors. In stock at Digi-Key right now, you can order samples of your desired One Touch connectors tonight (https://www.digikey.com/short/rn8rw873) and receive them tomorrow!

We want to make lots of Feather RP2040s, so we can ship them to all the folks who are wanting them - so its important for us to make the test procedure super fast and simple. Thanks to Thach's intrepid work with USB, we can now use the Teensy 3.6's USB host support to 'drag and drop' a UF2 file over the USB interface to program it. At 100 KB/s, we can load our test program, verify all the hardware, and load a demo program all in under 2.5 seconds. When you're making thousands of these boards, that time adds up so this will let us get you hardware faster!

The Great Search is a new series of videos focused on searching the Digi-Key catalog to narrow down to the parts you want to buy. This week:
The Great Search - The Great Search - Rotary Encoder with Switch https://www.digikey.com/short/fjc1vwh5
When you want to go round and round, a mechanical rotary encoder is a great user interface element. Folks find them intuitive to use and they're not too expensive either! For our new design, we need a mechanical rotary encoder with 24 pulses-per-rotation, detents, and a built in switch. Let's take a look on Digi-Key to see what's available!

iMX RT development returns to Adafruit, we're kicking off more development of this platform that got a little delay late last year. Keep your eyes peeled for the Metro iMX that will hit the store in a few weeks. For Stemma Sunday we started designing our QT mechanical keyboard breakout with 4 keys and neopixels. The QT Py RP2040 is ready to go, and we ordered PCBs! We're also experimenting with different Trinkey designs, like one with a rotary encoder.

We're living in a digital world, but eventually, every engineering project has to get down to the analog level. This week's EYE ON NPI is the Analog Devices AD5413 (https://www.digikey.com/short/pbqzchnr) is a 'swiss-army DAC' - a digital to analog converter that has a lot of extras to make it very easy for engineers who like to deal with bits and software, not analog components. Especially for those that need reliability and accountability in their electronic components!
Usage is pretty simple, the protocol is a classic SPI transmission. (https://en.wikipedia.org/wiki/Serial_Peripheral_Interface) 32 bits form one transmission, with one start bit, 2 address bits, 5 register bits, 16 data bits and 8 CRC bits. The two address bits are a little like I2C, even though this is SPI - you can have four AD5413's on one SPI bus with the same CS pin. A little uncommon, but maybe useful in low-pin-count or chained connections. The 5 registers let you set the voltage or current output, modes like single-ended or split-supply, check diagnostics and chip ID. Slew-rate management and overshoot compensation is all configurable. There's even a die temperature monitor! Compare this to most basic DAC chips where you only 'write' to the DAC, there's no registers or read-back for status.
With 14-bit voltage or current output, it's got high resolution and multi-project usage. It's designed specifically for industrial uses, (https://www.digikey.com/en/product-highlight/a/analog-devices/ad5413-digital-to-analog-converter) but we think it could also come in handy for analog electronics situations where you have biassing needs that require a split supply. Sure you could use a 0-3.3V DAC and then do a bunch of analog op-amp circuitry to get the range you want, but why add that complexity to your life? You'd have to deal with offset voltages and op-amp specifications when the AD5413 chip does it all!
Reading through the datasheet, (https://www.analog.com/en/products/ad5413.html) it's clear ADI really thought about everything that could go wrong in the field. The whole product is designed from bottom up to make reliability and error reporting easy to manage. For many products, the high integration may make it the only chip that is required for the analog-front-end. That leaves you, the engineer, with more time to work on firmware, and less time re-spinning boards and spec'ing feedback paths and compensation capacitors.
For a rock-solid industrial DAC with wide voltage range, voltage and current output, and more fault-management than the US Geological Survey (https://www.usgs.gov/), pick up an Analog Devices AD5413 (https://www.digikey.com/en/products/detail/analog-devices-inc./AD5413BCPZ/13146536) - it's an all-in-one solution for industrial/automation needs with excellent documentation and an eval board you can buy right now. (https://www.digikey.com/en/products/detail/analog-devices-inc./EVAL-AD5413SDZ/12697942). Order the AD5413 today (https://www.digikey.com/en/products/detail/analog-devices-inc./AD5413BCPZ/13146536) for immediate shipping, and you can have it in hand tomorrow for integration into your next industrial design!

The Great Search is a new series of videos focused on searching the Digi-Key catalog to narrow down to the parts you want to buy. This week:
Like many great parts, our go-to resistive touch controller chip, the STMPE family, has finally gone completely EOL - we are no longer able to source this part. Time to find a replacement! Let's find one with good pricing, and Linux Kernel compatibility. Will we be able to find one that is both I2C and SPI? Tune into The Great Search to find what we picked out for sampling!

The Great Search - Resistive touch screen driver replacement for STMPE610/STMPE811 https://www.digikey.com/short/7mt7b04f A week or two ago we showed off some mechanical keyboard ideas we had. Well, prototypes came a few days ago and we quickly threw together prototypes for the individual MX/Kailh breakout and a dual-key FeatherWing. The reverse-mount NeoPixel works with a simple fix, too. We also threw togehter a DVI breakout for use with RP2040 video demos and tested it. ForStemma Sunday, the TCA4307 is a hot-swapping I2C adapter, helpful to avoid bus glitching for hot-plug I2C buses! We also have a SNEAK PEEK world premier of a new not-public-yet Digi-Key service launch. Like many great parts, our go-to resistive touch controller chip, the STMPE family, has finally gone completely EOL - we are no longer able to source this part. Time to find a replacement! Lets find one with good pricing, and Linux Kernel compatibility. Will we be able to find one that is both I2C and SPI? Tune into The Great Search to find what we picked out for sampling!

This is an easy-to-read CO2 monitor that uses the SCD-30 NDIR CO2 sensor connected up to a Matrix Portal + 64x32 Matrix. It's super visible and gives visual hints so you know when its time to crack open the window, or when you're in good shape. We're seeing a lot of students+teachers want to build something like this for their classrooms so this version could be helpful - its totally plug and play thanks to Stemma QT!

Deep Dive happens every week. Normally Fridays at 2pm Pacific but occasionally shifted to Thursday at 2pm. Typically goes for two hours or more. Questions are welcome. Next week is on Friday. If you are outside the US, double check the time because the US is changing this weekend. Time change in USA
0:00 Getting things going 03:09 hello 06:56 housekeeping 11:25 How do you keep the cats away from the workstation and hot irons? 12:40 how far is circuitpython's implementation of asynchronous I/O scheduler (uasyncio)? 14:44 Is there a time you'd pick the STM32F405 Feather over the SAMD51 feather? They seem similarly capable, but Adafruit seems all-in on the SAMD51 16:10 there was no feather airlift so ordered 1 on digikey which has not even shipped yet Ordered another airlift yesterday from adafruit when it came back in stock so which one will show up first? 18:05 Feather RP2040 flash speed fix 18:34 OSHPark USBmicromod/v1 19:29 Are you using debug-edge in anything? Know anyone else who is using it? 24:58 SMT assembly at OSH Park ( no ) 25:11 how does OSH's flex pcb compare to the flex PCB on the neopixel/dotstar strips 26:41 Overhead / RP2040 feathers… flash socket 34:30 How big flash chip we can use with Metro/Feather M4 express? I tried mounting 64Mb but circuitpython didn't support it!!! 35:37 nvm.TOML improvements 38:43 Salea Logic Pro 16 work 40:52 Is there a good small library for ingesting uart stuff, and parsing into variables, in CP ? (for multi headed use cases) 41:19 back to the logic analyzer…. Examining the clock speed up during the boot process 51:10 Luke mentions RXDLY see boot2_w25q80.S for reference 55:46 Well it delays your sampling to the point in time where you launch the next clock transition which should still give you plenty of hold time because your data hold will be equal to round trip delay so RX_SAMPLE_DLY = 1 should be fine for BAUDR = 2 ha, I bet the second read is the hardfault vector fetch 58:35 - works one time when new software is installed, but not on power up 1:00:30 is there a good source to understand how PIO was implemented? Its not part of the M0 "platform", right? So I'm assuming it’s something uniquely developed for the RP2040 1:01:30 updating firmware again…. 1:06:09 Lady Ada drops in1 1:07:14 ItsyBitsy RP2040 prototype ( launching with 4MB flash? ) Discussion of Flash speed 1:17:30 - Luke added “there is more timing to play with -- for boot2_w25q80 we also disable input schmitt to get good setup timing. Have run the winbond devices at their max 133 MHz SCK reliably” (with RP2040 running a bit off-label :-) ) 1:21:11 ‘quad enable bit non-volatile’ frustration / warning…. 1:38:40 - catch desk of ladyada on Sunday! 1:39:15 bye LadyAda 1:39:30 Does this relate to the QT-Py flash? 1:40:02 so is there a volatile QSPI enable also? 1:41:25 Can Micro Python libraries work on Circuit Python? 1:42:06 Schmidt Trigger idea from Luke … 1:44:02 how do you get those cool colors and such in your terminal prompt?? 1:44:20 Scott’s quick build machine -j32 1:48:45 commit code before moving back to C… 1:52:40 Did you get the Pomona clip working from last week? 1:53:30 What are you not allowed to tell us ? 1:55:15 is that 2 x 5 SWD header difficult to solder on? 1:56:55 how many times is a decent test for reliability in this sort of case? 1:59:25 rebase code 2:00:30 responding to spam calls .. 2:01:00 pull request 2:02:30 why are you using Mac? and why not Linux? 2:03:29 so what do you use to capture the camera feeds? 2:05:14 wrap up 2:06:28 sign off 4:07pm...

Build a 3D printed enclosure for your IOT Air Quality Sensor. This project uses sensors to measure PM2.5 (particles that are 2.5 microns or smaller in diameter) dust concentrations, temperature and humidity.
This weatherproof enclosure is modeled after a silo-home. We've included different types of mounting holes and brackets for different mounting configurations.

Mmm-mm we like the sound of this new microphone from CUI Devices - the new CMM-4030D-261-I2S (https://www.digikey.com/en/products/detail/CMM-4030D-261-I2S-TR/2223-CMM-4030D-261-I2S-CT-ND/13404679?itemSeq=343478410) That part number is quite a mouthful, but also pretty descriptive since 4030 is the size of the mic (4x3mm) and I2S is the interface it uses for audio. The reason we picked this for EYE on NPI? It's the only top-ported I2S microphone available on Digi-Key and we've been looking for one for a while!
If you've ever designed a product with a microphone input you know you basically have two choices - good ol' electret microphones (https://www.adafruit.com/?q=electret&sort=BestMatch) or MEMS-based mics. (https://www.cuidevices.com/blog/analog-or-digital-how-to-choose-the-right-mems-microphone-interface). Electrets have been around for decades, are very inexpensive and easy to use. However, they have a few big downsides - one is you can't SMT reflow them (or at least, not any of the low cost one's we've ever seen or used) - they must be hand/selective/wave soldered instead. Two, they are analog output and need an amplifier. The amplifier is not a big deal, but if you want to have digital input into your chip, single board computer, or FPGA, you need to then get a separate I2S audio converter chip (https://www.digikey.com/en/products/filter/interface-codecs/716). Either way, if you're trying to avoid non-SMT assembly steps, that low cost electret isn't as low cost anymore!
OK so next you look at MEMS mics - created by measuring the capacitance change in a MEMS diaphragm when sound pushes it towards a matching plate. (https://res.mdpi.com/d_attachment/micromachines/micromachines-09-00323/article_deploy/micromachines-09-00323.pdf) Because they are solid state, you can pick and place and SMT reflow them for easy manufacture. They're also much smaller and thinner than electrets, so they're great for making tight builds. So, problem number one is solved! And, unlike electrets, you can get them with three different output options: analog, PDM and I2S (https://www.cuidevices.com/catalog/audio/microphones/mems-microphones) Analog is the earliest and simplest - the capacitance change in the MEMS transducer is converted to a small analog value and piped out one of the pins. (https://www.cuidevices.com/product-spotlight/mems-microphones#5) You still need to amplify it, but any op-amp will do the job. Pro: cheap, simple, great if you have an analog input, can replace electret analog circuits. Cons: Need an extra op-amp and passives, analog input. Next up is PDM output - which is a weird semi-analog digital signal. Like PWM, if you were to low-pass filter PDM, you'd get an analog signal, but you get the benefit of clock-synced output. And it's really simple with only two pins needed for stereo microphone in (one has data on falling clock, one on rising). You do need to do heavy filtering to get rid of the square wave 'carrier' but that's often handled within the PDM peripheral on your chip - at worst you can sorta treat it like an SPI device at 1 MHz and perform the filtering yourself in code. (https://github.com/adafruit/Adafruit_ZeroPDM) Pros: cheap, fairly simple if you have a PDM peripheral on your chip. Cons: You need that special peripheral!
So finally we get to I2S, which was how we got here in the first place! I2S microphones have a true I2S interface, so they work with many more chips including existing codecs that expect I2S inputs. For example, Raspberry Pi computers and other Single Board Linux computers often don't have PDM inputs, but they do have I2S! So you can wire this microphone directly to a Pi. (https://learn.adafruit.com/adafruit-i2s-mems-microphone-breakout/overview) Also many other chips, even if they don't have PDM or you don't want to use analog, will have solid I2S support. Only downside is that, at least for now, I2S mics are more expensive than PDM or analog - but they may be cheaper than analog mics + a codec or ADC! And they're definitely small so if you want to have a very compact build, they're great.
Like we mentioned at the beginning, this is the first top-ported I2S microphone we've seen, so we're happy we can pick one up to use in a future design. Digi-Key has a bunch of CMM-4030D-261-I2S-TR in stock right now (https://www.digikey.com/en/products/detail/CMM-4030D-261-I2S-TR/2223-CMM-4030D-261-I2S-CT-ND/13404679?itemSeq=343478410), you can order tonight and have it by tomorrow morning, save yourself some time by downloading the CAD footprint from SnapEDA (https://www.snapeda.com/parts/CMM-4030D-261-I2S-TR/CUI%20Devices/view-part/?ref=digikey) while you wait for the package to be delivered!

Full Tutorial: https://learn.adafruit.com/how-to-solder-headers/overview
Headers are like the duct tape of electronics. They're great for connecting things together, soldering to perf-boards, or preparing boards for plug-in components like servos or sensors.
Using headers with your microcontroller can make your life much easier, but soldering them on can be a little intimidating to beginners. There are a lot of ways to get it wrong, and once a header is soldered onto a board it's difficult or impossible to get it off again.
The written tutorial at learn.adafruit.com will teach an easy and reliable way to attach your headers, with tips for getting them on straight and accurate, so you can move on with your project with confidence. It will also give advice about pitfalls to avoid, and what to do when you get them on wrong.

This week's EYE on NPI is particularly useful for folks who care about air quality - it's the new SN-GCJA5 particulate sensor from Panasonic (https://www.digikey.com/en/product-highlight/p/panasonic/sn-gc-series-laser-type-pm-sensor)! This compact sensor uses a laser diode to measure light scattering caused by small inhalable particles in the air. It's great for measuring the dustiness of the air - such as that caused by smog or smoke. Especially useful for both home and industry - if you live or work near a high-risk fire zone you know how useful this is for telling you if a filtration mask is needed.
Panasonic's laser type PM sensor is an addition to its already broad range of specialty sensor solutions. It is comprised of an on-board microprocessor, micro-fan, and laser diode. This sensor has been programmed so that the fan will operate based on the amount of particle dust surrounding the laser diode so that overall lifespan or usefulness of the sensor can be extended much longer than its average commercially available equivalent.
Featuring a very small footprint of 37 mm x 37 mm x 12 mm, the Panasonic laser type PM sensor can be used to detect a wide variety of PM including, but not limited to, dust, fly ash, soot, smoke, aerosols, fumes, mists and condensing vapors, solid fuels, construction materials, cooking/smoking of plant matter, fireplaces and furnaces, house/forest fires, waste incineration, and much more.
A few things make this sensor stand out in a popular market. One is a dual-interface connector that supports both I2C and UART. The UART data comes in as plain text at 9600 baud, so it's easy to parse. The I2C interface means it's easy to use with boards that don't have a spare hardware UART. Only thing to watch for is that the power is 5V as there's a little fan inside that needs extra power, and the logic level is 3V so a shifter or booster may be required.
For quick testing, you can wire up a USB to Serial console cable (https://www.adafruit.com/product/954). We can use the included Windows program to quickly get data from the COM port and display it. The version of the sensor we picked up even came with a cable for easy plugging. We used some solder fumes from a handy iron to trigger the sensor into reporting a smoggy environment.
You can order this nice new sensor from Digi-Key, they're a big distributor of all things Panasonic from batteries to capacitors. Hey, we even have a video we did with them a year ago you can watch (https://www.youtube.com/watch?v=02PthE9DJxI)
Note there's two versions, we recommend the one with the cable but you can get your own cable made to match, the connector is a JST SM05B-GHS (https://www.digikey.com/en/products/detail/jst-sales-america-inc/SM05B-GHS-TB-LF-SN/807789).
Either way the price is very competitive, so you can add a particulate sensor for under $20 in quantity. Pick up a SN-GCJA5L sensor today to try out how elegant & easy it is to use! (https://www.digikey.com/en/products/detail/panasonic-electronic-components/SN-GCJA5L/10443900)

Every Sunday we work on a new STEMMA QT board - this week we made one for the MCP9601 - an I2C capable thermocouple sensor. This is one of the only I2C thermocouple AFE's we've seen, and we've already got a library for the earlier MCP9600. (The MCP9601 adds open-thermocouple detection!) We also worked on the Feather M4 CAN - with Arduino and CircuitPython support nearly wrapped, its time to finish the hardware. We have a few changes we made to reduce the power draw and got down to 250uA in sleep mode....but could we go lower?

Full tutorial: https://learn.adafruit.com/hallowing-flapping-bat/overview
Twinkle, twinkle, little bat! How I wonder what you're at! Up above the world you fly, Like a teatray in the sky.
The Mad Hatter Alice in Wonderland by Lewis Carrol
Make a spooky bat out of chipboard and decorate it with your best Halloween colors, sparkles, and ribbons. A little hot glue and crafting, and you're ready to hang it above your door, where unwary passers-by will brush past and trigger your bats wings to flap up and down, scaring them out of their pants!
You don't need a fancy motion sensor to trigger this halloween effect. The bat wings are triggered by a strand of conductive thread tied to the Hallowing's onboard capacitive touch sensor. Anyone who comes in contact with the secret dangling thread will cause the bat to leap into motion.
The Hallowing board is the spookiest, creepiest, scariest microcontroller around. Its skull face and winking OLED eye are sure to frighten even the bravest of makers when you program it to go Bump in the Night.

Full tutorial: https://learn.adafruit.com/halloween-costume-face-mask/overview
Halloween is such a fun holiday, and traditionally includes mask-wearing to complete your costume. This year, face masks have been a daily fashion choice for many of us, so here's a guide that focuses on making that face mask a little extra special for the spookiest day of the year.
Use colored felt to add a bird beak or monkey face to any face mask. Or create a "plague-doctor" style mask from scratch to bring a bit of historical authenticity to your costume this year.
We've included printable patterns and sewing directions. You'll need fabric and interfacing or craft felt, scissors, pins, and a sewing machine (or a needle and thread and some patience).

We made a new STEMMA board this week, thanks to a special request we got online - this one is for Wii Nunchuks! We also spent more time with various E-Ink displays to add more support for grayscale mode in monochrome and tricolor (!) displays - we had to do a big refactor of our Arduino EPD library to allow so many new display configurations! Also, the community came together and did a lot of research into up-and-coming M.2 module specifications.
The Great Search: M.2 "E Key" Connectors
If you want to add an M.2 modules to your PCB, there's plenty in stock at Digi-Key to choose from. We'll show what to look for (it isn't obvious how to find em!) and some nifty new features of Digi-Key's site, like 3D PDFs and ready-to-use CAD file downloads for instant integration with KiCad, Eagle, OrCad, Altium, etc!

This week's EYE ON NPI product is under a lot of pressure to perform, and does the job with aplomb ... because this week's NPI is the Bosch BMP390L high-precision barometric pressure sensor. (https://www.digikey.com/en/product-highlight/b/bosch-sensortec/bmp390l-pressure-sensor)
This is the latest in a long line of excellent barometric pressure sensors from Bosch. Why we remember the BMP series back when it was a wee BMP085 - it seems like just about every year there's been an improvement: the BMP180, BMP280 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/2651/5604371) - still a very popular chip! And the BMP388 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/3966/9685338)
With each generation comes an improvement in the pressure accuracy and precision. Earth's ambient barometric pressure changes with altitude - because air gets thinner the higher you go. (https://en.wikipedia.org/wiki/Atmospheric_pressure) There's a simple calculation that can be used to determine relative altitude changes and, if you know the sea level pressure (which usually doesn't vary much) you can use that to determine the absolute altitude. The better and more accurate your pressure readings, the better your altitude calculation output.
Historically, these sensors could give you about 1 or 2 meter accuracy in altitude detection. This new version has a relative accuracy of 3 Pascals, which translates to about 25 cm. All in a tiny 2mm x 2mm package with both I2C and SPI interfaces. (https://www.bosch-sensortec.com/products/environmental-sensors/pressure-sensors/pressure-sensors-bmp390.html). This makes them great for use with drones: paired with a GPS and IMU, you'll get great absolute-positioning and improve altitude stability.
Since barometric pressure is also used to perform weather predictions, this sensor is also excellent for any sort of ambient weather detection - just like the 'analog' barometers we had when I was growing up. Low pressure means air is moving in bringing clouds, storms and wind, high pressure means air is moving out so there will be fair weather without clouds. (https://en.wikipedia.org/wiki/Pressure_system) In addition to pressure, you also get temperature sensing, which is used to calibrate the pressure reading, but can also aid in environmental sensing.
Thankfully, this chip is pin compatible with the BMP388, so we were easily able to put together a demo to test this out. We updated our GitHub repo for the BMP3XX series to add support for the BMP390 as well so you can use any Arduino-compatible to talk to this fancy new chip (https://github.com/adafruit/Adafruit_BMP3XX). Bosch also has a C API that we found easy to integrate into any existing framework - you just provide the underlying I2C/SPI calls.
Digi-Key has some in stock right now at https://www.digikey.com/short/zn2pfn - place and order today and you can start integrating these new chips to upgrade your sensor platform tomorrow!

This EInk display with ESP32S2 WiFi is running CircuitPython to get the current bitcoin price and display it on the 2.9" e-paper. There are 4 neopixels on the front and 4 buttons, and we got the neopixels + buzzer working today so it can alert you audibly. On the back, 4 SMT standoffs screw into magnetic feet often used for RGB matrix displays. That means we can attach it to anything ferrous like this AV stand!

Make a display for your display! Show off your message to the world. This guide will show how to set up and assemble a Matrix Portal and RGB Matrix display, then make a transparent pocket in your backpack, purse, or messenger bag to show it off.
There is also a simple code example that displays your bmp images in slideshow fashion. Use the onboard buttons to switch between folders and play different messages, or pause on your favorite image. Set your bag down and the onboard accelerometer will sense that you're not moving and dim the screen to save battery life.
You can also use any of the other Matrix Portal code samples to get you started. Get ready to have fun with all the features the Matrix Portal offers.
Plug directly into the back of any HUB-75 compatible display (all the ones we stock will work) from 16x32 up to 64x64! Use the included screws to attach the power cable to the power plugs with a common screwdriver, then power it with any USB C power supply. (For larger projects, power the matrices with a separate 5V power adapter)
Then code up your project in CircuitPython or Arduino, our Protomatter matrix library works great on the SAMD51 chipset, knowing that you've got the wiring and level shifting all handled. Here's what you get:
ATSAMD51J19 Cortex M4 processor, 512KB flash, 192K of SRAM, with full Arduino or CircuitPython support ESP32 WiFi co-processor with TLS support and SPI interface to the M4, with full Arduino or CircuitPython support USB Type C connector for data and power connectivity I2C STEMMA QT connector for plug-n-play use of any of our STEMMA QT devices or sensors can also be used with any Grove I2C devices using this adapter cable JST 3-pin connector that also has analog input/output, say for adding audio playback to projects LIS3DH accelerometer for digital sand projects or detecting taps/orientation. GPIO breakouts including 4 analog outputs with PWM and SPI support for adding other hardware. Address E line jumper for use with 64x64 matrices (check your matrix to see which pin is used for address E! Two user interface buttons + one reset button Indicator NeoPixel and red LED Green power indicator LEDs for both 3V and 5V power 2x10 socket connector fits snugly into 2x8 HUB75 ports without worrying about 'off by one' errors. The Matrix Portal uses an ATMEL (Microchip) ATSAMD51J19, and an Espressif ESP32 Wi-Fi coprocessor with TLS/SSL support built-in. The M4 and ESP32 are a great couple - and each bring their own strengths to this board. The SAMD51 M4 has native USB so it can show up like a disk drive, act as a MIDI or HID keyboard/mouse, and of course bootload and debug over a serial port. It also has DACs, ADC, PWM, and tons of GPIO, so it can handle the high speed updating of the RGB matrix.
Meanwhile, the ESP32 has secure WiFi capabilities, and plenty of Flash and RAM to buffer sockets. By letting the ESP32 focus on the complex TLS/SSL computation and socket buffering, it frees up the SAMD51 to act as the user interface. You get a great programming experience thanks to the native USB with files available for drag-n-drop, and you don't have to spend a ton of processor time and memory to do SSL encryption/decryption and certificate management. It's the best of both worlds!
Comes with one fully-programmed and assembled MatrixPortal, preprogrammed with a rainbow digital sand demo for 32x64 LED matrices.
Does not come with an RGB Matrix (use any HUB75 compatible matrix) or a USB type C power supply!

This 2.9" grayscale E-paper display makes for a nice pairing with the ESP32-S2 WiFi module. Four buttons and 4 NeoPixels on the front (side lighting so it will illuminate the paper display!), and a whole party on the back. Accelerometer, speaker/buzzer, light sensor. Battery charger and lipo battery spot. USB C + on-off switch, plus a few low power hacks. Could make for a nice little wireless display that runs for a long time, we like that the EPD refreshes in under a second and is really crisp! Coming soon!
We call our series of E-Ink displays, THINK INK https://adafruit.com/thinkink

A Raspberry Pi with PiTFT makes for a perfect ESP32 tester/programmer, we just have it run esptool and program in a self-test sketch to the ESP32, then read the output from over the USB serial connection.
The self test checks all the pins are connected properly - not floating, not shorted - as well as the power supply voltages and battery charger functionality. Then once it passes test we program in CircuitPython 6!

Sunday's stand for STEMMA, and we made a new one today - using the BMP390 precision altimeter. We're also slowly cranking away at projects for the Stemma Friend board we showed off last week doing I2C scanning. This time we'll have it sniff the I2C connection. Then, we'll chat about chaining LED matrices using IDC cables.
The Great Search: Chain LED Matrices with IDC Cables
RGB Matrices have IDC cables that chain the shifted data down, you can get custom IDC cables in any configuration you can dream of from Digi-Key. We'll show you how and point out some of the things to watch for when getting IDC cables like polarizing keys, strain reliefs, and more!

Order your Matrix Portal Controller here: http://www.adafruit.com/matrixportal
RGB Display Sold Separately - we have lots of sizes available! https://www.adafruit.com/category/327
Folks love our wide selection of RGB matrices and accessories, for making custom colorful LED displays... and our RGB Matrix Shields and FeatherWings can be quickly soldered together to make the wiring much easier. But what if we made it even easier than that? Like, no solder, no wiring, just instant plug-and-play? Dream no more - with the Adafruit Matrix Portal add-on for RGB Matricies, there's never been an easier way to create powerful Internet-connected LED displays.
Plug directly into the back of any HUB-75 compatible display (all the ones we stock will work) from 16x32 up to 64x64! Use the included screws to attach the power cable to the power plugs with a common screwdriver, then power it with any USB C power supply. (For larger projects, power the matrices with a separate 5V power adapter)
Then code up your project in CircuitPython or Arduino, our Protomatter matrix library works great on the SAMD51 chipset, knowing that you've got the wiring and level shifting all handled. Here's what you get:
ATSAMD51J19 Cortex M4 processor, 512KB flash, 192K of SRAM, with full Arduino or CircuitPython support ESP32 WiFi co-processor with TLS support and SPI interface to the M4, with full Arduino or CircuitPython support USB Type C connector for data and power connectivity I2C STEMMA QT connector for plug-n-play use of any of our STEMMA QT devices or sensors can also be used with any Grove I2C devices using this adapter cable JST 3-pin connector that also has analog input/output, say for adding audio playback to projects LIS3DH accelerometer for digital sand projects or detecting taps/orientation. GPIO breakouts including 4 analog outputs with PWM and SPI support for adding other hardware. Address E line jumper for use with 64x64 matrices (check your matrix to see which pin is used for address E! Two user interface buttons + one reset button Indicator NeoPixel and red LED Green power indicator LEDs for both 3V and 5V power 2x10 socket connector fits snugly into 2x8 HUB75 ports without worrying about 'off by one' errors. The Matrix Portal uses an ATMEL (Microchip) ATSAMD51J19, and an Espressif ESP32 Wi-Fi coprocessor with TLS/SSL support built-in. The M4 and ESP32 are a great couple - and each bring their own strengths to this board. The SAMD51 M4 has native USB so it can show up like a disk drive, act as a MIDI or HID keyboard/mouse, and of course bootload and debug over a serial port. It also has DACs, ADC, PWM, and tons of GPIO, so it can handle the high speed updating of the RGB matrix.
Meanwhile, the ESP32 has secure WiFi capabilities, and plenty of Flash and RAM to buffer sockets. By letting the ESP32 focus on the complex TLS/SSL computation and socket buffering, it frees up the SAMD51 to act as the user interface. You get a great programming experience thanks to the native USB with files available for drag-n-drop, and you don't have to spend a ton of processor time and memory to do SSL encryption/decryption and certificate management. It's the best of both worlds!
Comes with one fully-programmed and assembled MatrixPortal, preprogrammed with a rainbow digital sand demo for 32x64 LED matrices.
Does not come with an RGB Matrix (use any HUB75 compatible matrix) or a USB type C power supply!

This weeks EYE on NPI is a sensor with a magnetic personality and we're really attracted to it...You guessed it - we're looking at the latest 3D magnetic field sensors from Melexis, the MLX90395 (https://www.digikey.com/en/product-highlight/m/melexis/mlx90395-triaxis-magnetometer) These are some of the few high-magnetic-field sensors available, with up to +-120mT, that's 1200 Gauss! Incredible when you consider many of our common magnetometers for IMU usage top out at +-50 Gauss. The sensor also has high precision, with 16-bit output and built in over-sampling since magnetometers can be a little noisy.
This sensor isn't great for IMU usage -- you'll want to stick to ~1 Gauss ranges for detecting Earth-level fields (https://en.wikipedia.org/wiki/Earth%27s_magnetic_field). But it is excellent for magnetic field sensing such as that of a rare earth magnet. These chips are often used for 3D motion sensing of an object, when it has a magnet embedded in it. Especially joysticks and other user controls, you get the environmental robustness of optical with the cost of mechanical. Plus you get Z axis motion which optical doesn't like as much. With a little bit of math you can detect various motions, positions, twists and distances, all without any mechanical wear. (https://www.youtube.com/watch?v=AMbkFrGe5Ws)
The sensor is available in both 50 and 120mT ranges, and in a few packages. We happen to like the QFN because it's pin-compatible with the earlier MLX90393 (https://www.adafruit.com/product/4022). Note that it is not code-compatible with the '393. For interfacing you can use I2C or SPI, with free-running or one-shot modes. There's an interrupt pin for data ready checking, and a trigger pin if you want to trigger readings with GPIO rather than requesting over I2C/SPI. We whipped up a driver over the weekend for people to use to get readings with an over-sample filter to help smooth out the readings. (https://github.com/adafruit/Adafruit_MLX90395)
It's great to see revisions of sensors come out that give us better accuracy and precision, with wider ranges and lower prices and the MLX90395 does not disappoint. When ordering, check the last few digits of the product order code since there are two versions. The -10x series is 120mT and the -00x series is 50mT, you'll get a trade-off of precision and range.
Digi-Key has these in stock right now in a variety of packages from SOIC to QFN to TSSOP and ready to ship today for delivery tomorrow morning (https://www.digikey.com/en/products/detail/melexis-technologies-nv/MLX90395KDC-BBA-101-RE/12330664)

Full tutorial: https://learn.adafruit.com/led-neon-selfie-spot/overview
People love taking selfies. More and more businesses and events are taking note of this fact and building in locations where people can stand and get a really great selfie for Instagram or Facebook, or a unique and fun video for TikTok. And with the Zoom Boom happening thanks to Covid 19, people want interesting backdrops in their homes as well.
This guide will show you how to build your own custom selfie spot out of LED Neon. It's easy to assemble, it's mobile, and it's also easy to take apart and re-configure, when you decide you're ready for a change of scenery.
There's no coding required. Just choose the colors you want, lay them out, and plug them in to get a magical glowing wall of selfie goodness.

STEMMA Friend is your I2C pal - I2C scanner demo
This little board is something we designed to help me with I2C device development. It's got a SAM21 on the back, and two I2C ports (one STEMMA QT and one Grove compatible JST) We imagine it will be sort of a Swiss Army Knife of I2C hacking. First demo is a simple I2C scanner. Just tells you what addresses ACK on the I2C bus. Handy for a first check of new designs! Next up...an I2C sniffer - stay tuned!

In this project we’re making a tombstone with Adafruit’s Matrix Portal! Guide: https://learn.adafruit.com/tombstone-matrix-portal
We upgraded this foam tombstone with an RGB matrix so we can display animated graphics.
The Matrix Portal is a plug-n-play dev board that makes these types of projects fairly easy.
We designed and 3D printed these brackets so we can attach this to things like halloween props, picture frames or just some foam core.
The 3D skull is just a bitmap sprite sheet that is animated using Circuit Python! With Circuit Python, you can animate sprites sheets and display them on the matrix.

The MLX90395 is a new magnetometer from Melexis, its ultra high range, can do +-120mT (that's milliTesla not microTesla!) so its great for detecting strong magnetic fields. We wrote up a library for it over the weekend and will be ordering the PCBs shortly.

This week's EYE ON NPI is the ideal tool for your workbench, and that isn't hyperbole - it's the WS3620.ITU wire stripper from Ideal-Tek (https://www.digikey.com/en/product-highlight/i/ideal-tek/adjustable-wire-strippers), a Swiss company that is making really nice bench-top tools. (https://www.ideal-tek.com)
Ideal-tek's adjustable wire strippers offer fast and safe stripping of the finest and most flexible conductors, strands, or wires in diameters from 0.12 mm to 0.8 mm (36 AWG to 20 AWG). Most wire strippers end at 30 AWG, or struggle at 30 AWG and don't give you a clean cut. Some are automatic-style but are heavy and clunky. This tool is very light, easy to use, and works flawlessly down to 36 AWG so it's great with our extremely fine stranded wires (https://www.adafruit.com/product/4733) There's an adjustable stop so you can get the same lengths every time. Worked great when we tested with silicone, PVC or Teflon coverings. Features For 0.12 mm to 0.8 mm (36 AWG to 20 AWG) wires Automatic wire cross-section scanning system Safe and suitable for right- or left-handers Adjustable length stop (5 mm to 45 mm) Impact-resistant plastic We got this tool for ourselves since we're doing a lot of fine wire rework on PCBs (https://www.adafruit.com/product/1446) and needed something that could cleanly strip 30~36AWG but now it's our new favorite thanks to its speed and reliability. We strongly recommend it! The price is also very reasonable for sub-30 AWG wire stripping!
Add it to your Digi-Key cart, so you have it when you need it - a good tool is worth its weight in gold and will save you a lot of frustration (and wire nicks).
In stock and shipping today, visit https://www.digikey.com/en/products/detail/ideal-tek-s-a/WS3620.ITU/13170711 to get a WS3620 and you could have it tomorrow morning!

This all-in-one Metro design is Arduino UNO shaped so it works with shields, and features an iMX RT1011 500 MHz processor with 128K of RAM and QSPI memory. Even though it doesn't have a ton of RAM, it's got a nice speediness to it which we really dig. Here we are testing out CircuitPython 6 with the AirLift WiFi co-processor to get data from the interwebs and display it on an OLED. The OLED plugs right into the stemma QT connector so its really easy to get sensors and displays attached!
This is coming soon and will be here - https://adafruit.com/new

Full Tutorial: https://learn.adafruit.com/glowing-bottle-lamp/overview
Make a beautiful rainbow colored glowing bottle lamp with fairy lights inside. You don't need to catch actual fairies, or chase down a real rainbow, but it will look as though you did! Decorate it with your favorite stickers and place it on your windowsill, and I guarantee you it will attract both rainbows and fairies into your life.
And couldn't we all use more rainbows and fairies?
Difficulty Level
This is a very easy beginner project that's perfect to do with kids who are interested in learning about making things light up. The assembly is easy enough for kids as young as 4-5 (with a little help from an adult). Kids that young can also pick their own colors with the MakeCode drag-and-drop app, and slightly older school-aged kids will have fun coding the whole project by themselves.
If you're a Grown Up Kid like me who still loves rainbows and fairies, this is a great place to get introduced to programmable lights, and you'll end up with a stunning piece of art when you're done. Let's get crafty and make stuff light up!

The Great Search is a new series of videos focused on searching the Digi-Key catalog to narrow down to the parts you want to buy. This week:
We needed a li'l Schottky diode for the QT Py board to allow external battery usage. Our standard MBR0540 and friends wouldn't fit...but we still want 1A current. Let's try to find the magical part that we can use to make this design work!

Each board gets fully tested and programmed after manufacture at Adafruit - here' the new QT Py tester! It uses a Teensy 3.6 and runs DAP code to program the QT Py's SAMD21 with a test program that checks all pin connections, then reprogams it with a shipping bootloader + firmware that swirls the onboard NeoPixel. We can fully test and program a QT in 2.6 seconds, nice and fast - https://adafruit.com/qtpy

This week's EYE on NPI is a breath of fresh air! How do we know it's fresh? Cause we have a brand new Sensirion SGP40 air quality sensor (https://www.digikey.com/en/product-highlight/s/sensirion/sgp40-d-r4) hooked up and ready to be our digital nose. We loooove Sensirion sensors, and we stock a whole bunch in the Adafruit shop. (https://www.adafruit.com/?q=sensirion&sort=BestMatch) They are renowned for their excellent prices and quality on temperature, humidity and gas sensors, so when we saw this pop up on Digi-Key at https://www.digikey.com/new, we quickly picked up a few pieces to check out.
The SGP40 is Sensirion’s digital volatile organic compounds (VOC) sensor designed for easy integration into air treatment devices and air quality monitors. Based on Sensirion’s CMOSens® technology, the SGP40 offers a complete sensor system on a single chip and features a digital I²C interface, a temperature-controlled micro-hotplate, and a humidity-compensated indoor air quality signal. In combination with Sensirion’s powerful VOC algorithm, the sensor signal can be directly used to evaluate indoor air quality for applications such as triggering the gradual fan control of an air treatment device. Both the SGP40 chip and VOC algorithm feature unrivaled robustness in the final application over their lifetimes. Pushing the multi-pixel and multi-hotplate approach to the next level of individual control of each sensing element, the SGP40 enables a drastic reduction in power consumption, making it suitable for battery-driven applications as well. Sensirion’s state-of-the-art production process guarantees high reproducibility and reliability.
Gas sensors are really interesting, they are all essentially resistive sensors, where the exposed silicon has a metal oxide layer (MOX) that is susceptible to ambient gasses. There's a heater element that you need to turn on, then wait till the silicon chunk can react with the air. The resistance changes with the amount of organic compounds in the air and you can measure the resistive differences. (https://www.sensirion.com/en/environmental-sensors/gas-sensors/)
Now for many gas sensors, you basically get 4 pins: two for the heater, and two for the resistor. You have to power the heater, then use a resistor divider or op-amp to read the resistance and back calculate. There's no built-in calibration available. What we like about the SGPx0 series is that you don't need the power control or analog input.
This isn't Sensirion's first gas sensor, we've already stocked the SGP30 for a while, (https://www.digikey.com/product-detail/en/adafruit-industries-llc/3709/1528-2531-ND/8258468) and there are a few things we really liked about that sensor that are the same on the SGP40. First is a dead-simple I2C interface, you send it some commands, it responds with the normalized resistance data reading. No complex code required, it's trivial to port to any microcontroller.
With a humidity sensor on the same microcontroller, you can feed the ambient RH to the SGP40 and it will improve the resistance calculation.
Check out the SGP40 at Digi-Key at https://www.digikey.com/short/zwzjqb
May we suggest one of the fine SHT3x series? (https://www.digikey.com/product-detail/en/sensirion-ag/SHT35-DIS-F2-5KS/1649-1067-6-ND/6212141) A PM2.5 sensor can also be added for a powerful all-in-one environmental-sensing kit (https://www.digikey.com/products/en?keywords=sensirion%20pm2.5)

Yow, this active terminator is really amazing, I'm able to run a 100 KHz I2C connection over a 100 foot CAT 5 cable we had lying around the house. The active terminator tends to the SDA and SCL pins, making them into nice square waves, solving a common engineering problem where folks want the convenience of I2C but the cable-length of 1 Wire.

Install a strip of NeoPixel lights in your bedroom or living space. Hook them up to a Circuit Playground Bluefruit and control the lights with your phone or tablet. You can add as many different animation modes as you like - it's really easy to do with Adafruit's CircuitPython LED Animations Library.
Choose from millions of colors with our graphical color picker. And, we've got around a dozen pre-written animations that you can customize to your heart's content including Rainbow, Pulse, Sparkle Pulse, Color Chase, Comet, and more. Within each animation you can set custom colors, speeds, directions and brightness. You can even layer the animations over one another to create your own custom animated lighting scenes.
Cycle through modes and fine-tune your brightness levels using Adafruit's free BlueFruit app, which works seamlessly with our CircuitPython sample code.

This upcoming Voice Bonnet adds stereo speaker/headphone/microphone to any Raspberry Pi to make machine learning projects easy. Here we're running the Google Assistant python example scripts, with a twist! Thanks to the STEMMA QT connector and CircuitPython Blinka library, we can add an OLED display that will print out what the voice engine has heard. We can also add prompts, LED feedback and use a button to indicate when we want the project to listen - stay tuned to: https://www.adafruit.com/new

Remember before we had ringtones, when every phone had the same tones to alert you when a call came in? Incredible we lived like that, like savages! This week's EYE on NPI will make you feel the same way about audio alerts, with this awesome new product from PUI, the API-4260-LW150-2-R (https://www.digikey.com/en/product-highlight/p/pui-audio/api-4260-lw150-2-r-programmable-indicator) - it's a programmable audio alert speaker with MP3 support, and now we can't understand how we lived without it.
Like our Sound FX boards (https://www.adafruit.com/product/2342) or CircuitPython (https://circuitpython.org/), it shows up as a 4 megabyte disk drive. We created our own custom EYE on NPI alert system by converting our WAV file to MP3 (to save space) using Audacity (https://learn.adafruit.com/microcontroller-compatible-audio-file-conversion). Then apply power and immediately the audio file starts looping! You can make the MP3 as long as you like, it just needs to fit in the 4MB disk drive space.
The PUI Audio API-4260-LW150-2-R is an audio programmable indicator (API). Instead of using software that only works on operating systems and some devices, programming the API only requires adding .MP3 and .WAV files to any computer that supports USB thumb drives.
A larger 4 MB storage size allows for longer files or sequential playback of multiple files, while the internal DAC allows for files with sampling rates up to 48 kHz.
The 150 mm lead wires and mounting flanges allow for easy product integration while activating the API-4260-LW150-2-R is as simple as supplying 7 VDC to 24 VDC.
With 100 dB of output at 10 cm (with a 1 kHz file recorded at 0 dB), users can employ the API in most ambient conditions. It complies with FCC Part 15 Class B, CE EN61000-6-1, and CE EN61000-6-3.
The speaker is surprisingly loud and you can't beat the simplicity of this design. The price isn't that much higher than non-programmable audio alert systems, and you save a ton of time on integration and programming: you don't have to add MP3 playback to your product if it's just to play alerts.
Thanks to the recent end of the MP3 patent pool, no licensing is required! (https://blog.adafruit.com/2017/04/18/is-mp3-now-patent-free-makerbusiness-technicolor/) What we like is the simplicity - simply power it and it does it's thing, so it can be integrated into any existing design without engineering re-work.
We were curious on what's powering this thing so we opened it up. Inside we found an XL2576 5V switching regulator (https://www.digikey.com/product-detail/en/texas-instruments/LM2576SX-ADJ-NOPB/LM2576SX-ADJ-NOPBCT-ND/3440107), a Winbond 25Q32 FLASH chip (https://www.digikey.com/product-detail/en/winbond-electronics/W25Q32JVSSIQ-TR/W25Q32JVSSIQTR-ND/5803982), and a GZUT-MA2 'all in one MP3 player' chip. The chip output goes into an audio amplifier chip and to an 8ohm 0.5W speaker.
Simple? Yes! Effective? Indeed! You can pick one up at Digi-Key and with its easy-to-use interface and add it to your next design within seconds! In stock now and shipping today at https://www.digikey.com/short/z2dp0z

The Great Search is a new series of videos focused on searching the Digi-Key catalog to narrow down to the parts you want to buy. This week:
Today we were working on an all-in-one CAN bus Feather. CAN bus is a protocol with a hardware signalling layer that is specified for 5V logic, and there's a 120 ohm termination resistor. This means we will need at least 50mA for the signalling control. Let's find a DC/DC converter that will get us a nice clean 5V with minimal cost and complexity on Digi-Key!

The Great Search: 5V Boost for CAN Bus Transceiver https://www.digikey.com/short/z2rt3m
Today we were working on an all-in-one CAN bus Feather. CAN bus is a protocol with a hardware signalling layer that is specified for 5V logic, and there's a 120 ohm termination resistor that means we will need at least 50mA for the signalling control. Let's find a DC/DC converter that will get us a nice clean 5V with minimal cost and complexity on Digi-Key!

Using the plug-in MatrixPortal board we just released last week, we were able to make a sign that we brought to the Ruth Bader Ginsburg memorial vigil in NYC. The code displays three initials and then scrolls through an image of the Justice. We used the matrix magnetic feet to temporarily attach it to PT's bag, it was solid but easy to remove at the end of the night.

This weeks EYE ON NPI gets REAL with the Intel RealSense LIDAR camera. (https://www.digikey.com/en/product-highlight/i/intel/lidar-depth-camera-l515) This surprisingly powerful camera is easy to use and has both color and LIDAR depth output data. This makes it perfect for use in robotics, interactive art, 3D scanning...all sorts of projects where spatial sensing is required. It was announced in 2019 but didn't start shipping until a few months ago.
Almost 10 years ago, Adafruit sponsored a Kinect-hacking bounty (https://blog.adafruit.com/2010/11/10/we-have-a-winner-open-kinect-drivers-released-winner-will-use-3k-for-more-hacking-plus-an-additional-2k-goes-to-the-eff/) to take an off-the-shelf video game accessory and turn it into a tool for anyone to use. The open source cross-platform drivers spawned hundreds of awesome projects, from the scientific and artistic, to the humanist and just plain silly (https://blog.adafruit.com/category/kinect-hacking/). With the Kinect discontinued (https://en.wikipedia.org/wiki/Kinect), it's been a challenge to find a low cost alternative with an easy API. Until now! This little sensor is smaller than a tuna can and is a complete system with plug-and-play USB type C port for power and data. There's even an BMI085 IMU inside! (https://www.digikey.com/product-detail/en/bosch-sensortec/BMI085/828-1083-1-ND/8634943)
Intel RealSense's L515 is a type of solid state LiDAR technology-based depth camera. It uses LiDAR technology to scan a full scene allowing it to provide a point cloud with up to 23 million points of accurate depth data per second. It delivers consistent high depth accuracy throughout the supported range of the camera starting at 25 cm up to 9 meters. The accuracy of the L515 within its operational range is less than 20 mm Z error at maximum range. With an internal vision processor, L515 achieves motion blur artifact reduction by an exposure time of less than 100 ns (nanoseconds), ideal for capturing rapidly moving objects with minimal motion blur. Additionally, the 4 ms photon to depth latency allows real-time applications such as autonomous navigation. An RGB camera, gyroscope, and accelerometer round out the capabilities of the device for high-quality performance and use case flexibility.
Smaller than a tennis ball, the Intel RealSense LiDAR Camera L515 has a diameter of 61 mm and is 26 mm in height. Weighing in at around 100 g (3.5 oz), it is designed to be easily situated on any prototype or attached to a tablet or phone for use in handheld room scanning or volumetric measurement applications.
The L515 uses the same open source Intel RealSense SDK 2.0 as all other current-generation Intel RealSense Depth Cameras, which is platform independent, supporting Windows, Linux®, Android™, and macOS. This includes wrappers for many common platforms, languages and engines, including Python, ROS, C/C++, C#, Unity, Unreal, OpenNI, and NodeJS, with more being added constantly.
Features Depth FOV (field of view): (H × V) 70°±2° x 55°±2° Depth resolution: Up to 1024 x 768 depth resolution (XGA resolution) Depth frame rate: 30 frames per second RGB frame rate: 30 frames per second RGB resolution: Up to 1920 x 1080 RGB resolution RGB FOV: (H x V) 70° ±3° x 43° ±2° Use environment: Indoor Inertial measurement unit: Bosch BMI085 Range: From 25 cm to 9 m range Connection type: USB-C® 3.1 gen 1 connection Dimensions: 61 mm diameter x 26 mm height Mounting: Two M3 x 0.5 mounting points and one 1/4 20 UNC thread mounting point
It shows up in a few ways when you plug it into your computer. For integration into projects that use OpenCV or other camera-based inputs, you will see a dual UVC camera one called 'Depth' which is the LIDAR and one called 'RGB' which is a regular camera that you can overlay over the depth data. The Cameras are really high res, as well - 1024x768 depth resolution and 1920 x 1080 RGB resolution. Compare that to the Kinect's 640x480! (https://en.wikipedia.org/wiki/Kinect)
We like that this sensor has industrial-quality sensing with engineer-and-maker-friendly development. No NDAs for datasheets, no signups for code - everything needed to get set up was shockingly convenient. (https://www.intelrealsense.com/get-started/) There's even a developer center (https://www.intelrealsense.com/developers/) with firmware upgrades, documentation, code samples, and a community group. There's a lot of support, so we think this is a great option for low cost depth sensing - a really fabulous NPI!
Interested? Of course, you are! Pick up an Intel RealSense camera from Digi-Key today, it's part number 2311-82638L515G1PRQ-ND, and you can have it ready for your next amazing project tomorrow morning! (https://www.digikey.com/product-detail/en/intel-realsense/82638L515G1PRQ/2311-82638L515G1PRQ-ND/11688015)

Full Tutorial: https://learn.adafruit.com/neopixel-led-necklace-insert-with-usb-charging/overview
Sometimes you want to add animated lights to your costume or project and you're really limited on space. Necklaces are a great example of this - a glowing pendant can be so striking, but if it's too big and bulky it can cross the line to "gaudy" pretty quickly.
This tutorial aims to make the smallest possible NeoPixel module or insert for your project. We've worked to make it super small, at around 1/2" thick and about 2" across.
This tiny package still contains all the niceties:
7-12 addressable NeoPixel lights A compact on/off switch A rechargeable battery with 4+ hours of battery life Onboard USB charging capability
We're using an Itsy Bitsy M0 microcontroller, which can be programmed with CircuitPython, MakeCode or Arduino, so you've got lots of options, and we've included an easy-to-customize code sample as well.

This week's EYE on NPI brings you Analog Devices' ADT7422 ultra-high accuracy and precision temperature sensor. (https://www.digikey.com/en/product-highlight/a/analog-devices/adt7422-01-c-accurate-digital-temperature-sensor) With an astonishing ±0.1°C rated accuracy, you can use this sensor for real-time, calibration-free temperature sensing. A built-in I2C ADC interface provides 16-bit data, so you could use this sensor with any microcontroller or microprocessor and get 0.0078 °C resolution. And you can have up to 4 of these sensors on a single I2C bus by changing the I2C address pins A0/A1.
ADT7422 is ADI's first ±0.1°C accurate temperature sensor that doesn't require any external circuitry for operation. It can easily replace more complex and expensive solutions that use alternative sensor technologies such as thermistors or RTDs. In addition, high-precision silicon sensors (ICs) are preferred options for a range of emerging applications in the healthcare market such as vital signs monitoring instruments for clinical and home use.
Features
±0.1°C accuracy specification enables the end product to measure temperature with accuracy that was only possible for thermistors and RTDs Doesn't require external circuitry: smaller, lower power, and lower cost than older sensing technologies Fully tested and calibrated solution: doesn't require system calibration to achieve desired ±0.1°C measurement precision The highest accuracy of ±0.1°C comes is achievable between 25°C ~ 50°C. From −20°C to +105°C the accuracy is ±0.25°C and from −40°C to +125°C its ±0.50°C. For high temperature ranges, such as for use with scientific or food processes, you probably want to go with a PT100/PT1000 RTD sensor interface (https://www.analog.com/en/applications/technology/precision-sensor-interface/temperature-sensing/rtd.html) - for example verifying the temperature of a yogurt processing system, or a chemical heater. These sensors are more tuned towards human/bio measurement - for example a long-term temperature/health monitor that uses skin temperature, implanted glucose monitor, or an incubator - all places where you want very high accuracy!
Interfacing with the chip is really simple, in fact we were able to borrow a lot of code from the ADT7410 (https://www.adafruit.com/product/4089) library we wrote a year ago (https://github.com/adafruit?q=adt7410&type=&language=) and read out the temperature in both C and Python. Analog Devices also has 'pure C' drivers available on GitHub (https://github.com/analogdevicesinc/no-OS/tree/master/drivers/temperature/adt7420)
We picked up one of Analog Device's dev boards. You can see a few interesting details like PCB slots to help keep the chip thermally isolated. There's also an Arduino-compatible Eval shield (https://www.analog.com/media/en/dsp-documentation/evaluation-kit-manuals/dc2026cfe.pdf) you can use to plug and play this sensor, but we found it works perfectly fine with plain 0.1" jumpers, just make sure you're giving it 3.3V for power!
Add tiny, accurate temperature sensing today by picking up an ADT7422 from Digi-Key, available in cut-tape & reel, by visiting https://www.digikey.com/short/zf0d21 Your order will ship same day and you can get it in hand the next morning!

The Great Search is a new series of videos focused on searching the Digi-Key catalog to narrow down to the parts you want to buy. This week:
Let's find an accelerometer for our next project, using Digi-Key! I2C or SPI? Analog or Digital? Range and bandwidth, we'll chat about these while we search for a nice sensor to include in some future designs.
We'll also check out an interesting capability for extra-deep-dives - the downloadable table export!

The BNO080 all-in-one 9 DoF IMU board is pretty nice - it can output accel/mag/gyro data as well as fuse sensor data together to give you Euler or quaternion orientation vectors. This sensor also has I2C, SPI and UART interfacing. UART means you can plug it into an FTDI cable directly and then run our BNO08x library to read the sensor data directly from a computer running Python!

CircuitPythonista Jepler requested that the QT Py have a spot for external flash chip on the bottom for expansion. Your wish is my command! Voila rev B, with a SOIC 8 on the bottom connected to a hardware SPI port. Not much else changed here, it is ready for another prototype revision and maybe a pretty silkscreen!
...and! here is the QT Py with lots of STEMMA QT devices: OLEDs and sensors - oh my! The QT Py is a SAMD21 board that can plug n play with any of our 50+ STEMMA QT boards, like this 128x128 OLED, PM2.5 Air Quality sensor, pressure/humidity/temp sensor and 9-DoF IMU. No soldering required, this is the easiest way to build electronics...coming soon to the adafruit shop! http://adafruit.com/qtpy

Folks love our PyPortal series, and we're working on making another version, this time with RGB matrix support instead of TFT for huge displays and clocks. The board plugs right in and is powered over USB C. Arduino or CircuitPython supported thanks to the new ProtoMatter library from PaintYourDragon. We tossed one of our favorite sensors, the ST LIS3DH on there as well - so make easy pixel dust projects! This is just our first proto, but looks good so far.

We just got our 7-color E-Ink display from Waveshare and its really cool! There's python code for drawing bitmaps to the display from Python. We are looking to maybe make some projects with this kind of display. It seems to have the same exact 'pinout' as other E-Ink displays we've seen. There are 7 colors - white, black, red, orange, green, blue, purple and they're a little watercolor-y which is a nice effect. Images must be dithered because you cannot 'mix' colors in E-Ink displays, only display one of the 7 available colors per pixel.

This week's EYE on NPI is all about discovering new things - the Digilent Digital Discovery with High-speed adapter bundle (https://www.digikey.com/en/product-highlight/d/digilent/digital-discovery-with-high-speed-adapter-bundle).
The Digilent Digital Discovery™ is a combined logic analyzer and pattern generator instrument that was created to be the ultimate embedded development companion. Digital Discovery was designed to optimize channels, speed, and portability. A small form factor facilitates easy storage and provides a whole suite of advanced features to allow you to debug, visualize, and simulate digital signals for most embedded projects. Digital inputs and outputs can be connected to a circuit using simple wire probes or breadboard wires; alternatively, the Digital Discovery High Speed Adapter and impedance-matched probes can be used to connect and utilize the inputs and outputs for more advanced projects.
We're big fans of the affordable and powerful Digilent Analog Discovery (https://www.adafruit.com/product/4652) so when this logic-analyzer version popped up on https://digikey.com/new we snapped it up to check out. The specifications of what you get, for the price, are pretty amazing:
32-channel digital logic analyzer (1.2…3.3V CMOS, 8 channels at 800MS/s, 16 channels at 400MS/s, and 32 channels at 200MS/s) Digital Bus Analyzers (SPI, I²C, UART, CAN, Parallel) 16-channel pattern generator (1.2…3.3V CMOS, 100MS/s) 16-channel virtual digital I/O including buttons, switches, and LEDs – perfect for logic training applications A programmable power supply of 1.2…3.3V/100mA. The same voltage supplies the Logic Analyzer input buffers and the Pattern Generator input/output buffers, for keeping the logic level compatibility with the circuit under test.
In particular, 32 channels of 200 MS/s logic analyzer input is rare to see in a sub-$1000 logic analyzer. 8 channels of 800 MS/s is also incredible, if you need that kind of speed, it's very hard to find an affordable analyzer. The wide/fast rates means this analyzer would be great for analyzing wide 8/16/24/32 address/data busses that normally you wouldn't have enough pins for. You could also check on fast protocols that normally aren't logic-analyzer friendly like RGB matrix and parallel TFT displays.
Inside is a Xilinx SPARTAN FPGA and some memory for buffering signals. Like many logic analyzers, the Digital Discovery connects over USB and uses free desktop software for communication. The software in this case is called Waveforms, and is available for Mac, Windows, and Linux including Raspberry Pi (https://store.digilentinc.com/waveforms-download-only/). The same software is used for the Analog Discovery, so if you've got one of those, it'll be familiar. The software is powerful and has a lot of options and capabilities, so we definitely recommend going through some of the tutorials available on Digilent's site, like this nice walk-through on analyzing an old-school NES controller - here's a hint, it uses a serial latch! (https://blog.digilentinc.com/nes-controller-digital-discovery-waveforms/).
What I use logic analyzers for is usually decoding I2C and SPI transfers while writing drivers. So I was happy to see a range of built in analyzers such as I2C, UART, CAN, even HDMI! To test it out, I connected the analyzer up to a BNO080 sensor I'm working on. I enabled I2C datalogging on the two initial pins. You can see the data stream with decoded hex values and read/write flags on initial addresses. You can also open up the events tab to see the data as a list with timestamps. The event data (or even the raw pulses) can then be exported to a spreadsheet.
There's also a powerful scripting system. You can perform analysis, read data and decode protocols. (https://blog.digilentinc.com/decoding-vga-on-the-digital-discovery/) There's also a logic waveform generator you can script as a simulator for devices. (https://reference.digilentinc.com/learn/instrumentation/tutorials/hd44780_digital_discoverystart) We're pretty confident saying that for the price, this is the fastest, most powerful, capable and customizable logic analyzer you can get. And for students, it's super affordable and easy to store. Pair this up with an Analog Discovery for a full EE lab without giving up tons of desk space.
Pick up a Digital Discovery from Digi-Key today at https://www.digikey.com/short/zfhz4r . You can pick up the version with high speed probe kit, or, if you aren't planning on using over 200 MS/s, the affordable basic version is at https://www.digikey.com/short/zfh997

We wanted to try out the Arduino Portenta that has arrived, and what better way than to test it out with our STEMMA QT boards? There's a 5 pin expansion port, which exposes the I2C pins and power+ground. Using our handy MKR to STEMMA cable https://www.adafruit.com/product/4483 we can plug in any of our 50+ sensors and displays. Here we show how adding an OLED and IMU is plug-n-play trivial and our examples just work!

Before we can start fabrication of a new design we need to design a tester - that way we can verify all the components and firmware are working they way they ought to. In this case, the Braincraft HAT https://www.adafruit.com/product/4374 has a TFT display, two microphones and two speaker outputs. We can use the speakers to test the mic's and vice versa by playing a sine wave through each speaker and then checking the sound level on the matching mic. We should see a big difference! the TFT is tested by having the text show up on it, and next up I'll add headphone jack and joystick tests. A quick but effective full-coverage test is essential to getting our high quality electronics out there.

If you want to run an I2C bus over very long wires, at high speeds, this active terminator could prove very useful! Stick it on the end of your long bus and it will automatically detect when the pullups are activated (e.g. SDA/SCL are floating) and yank them up. You can see here it turns a sawtoothy 800KHz bus into a beautiful square wave! We're gonna try running this over 100ft Ethernet next ...

The first step in a robotics project is to get a motor spinning. Once you've done that you quickly learn that not all motors go the same speed, even if they are the same part number! There are always variations that relate to voltage, environment, and manufacturing changes. This motor has a magnetic wheel and two hall effect sensors already attached. Using this motor is a breeze, and it's a nice small motor as well, in the 'standard' N20 size. Available in various gearings at https://www.adafruit.com/product/4638

This week's EYE on NPI is a new twist on an old familiar classic - cables and components from Harting (https://www.digikey.com/en/product-highlight/h/harting/t1-industrial-single-pair-ethernet-connector) for a new implementation of Ethernet connectivity called "Single Pair Ethernet" (https://www.single-pair-ethernet.com/en). We're interested in this because we have found that a lot of devices could benefit from a powered/wired network capability but Ethernet jacks are kinda huge and stiff - a single twisted pair cable could make wiring IoT devices easier and a lot less expensive because we don't need nearly as many conductors - wire is not cheap! - and we don't need a separate power adapter.
Ethernet was invented in the 70's, and although it has been improved greatly, the underlying connector and cabling has not changed much. SPE is designed to be compatible with existing Ethernet installations, there's going to be a translator chip, but the upper transport layers like TCP/IP will be the same. We're actually big fans of Ethernet compared to WiFi - since there's physical access you don't have to deal with SSIDs, passwords, or enterprise management. (https://learn.adafruit.com/alltheiot-transports) That makes it ideal for IoT because one thing that's super annoying about IoT products is deploying and updating when the WiFi credentials change. While we do see some IoT devices with Ethernet, it's not as common as dropping in WiFi support. Perhaps, given that you still need to plug in power, SPE can make some headway into the industry.
The specifications allow for up to 1000 meter long cables, 1 Gbps data rate and 50 W power transmission. (https://www.harting.com/SE/en-gb/single-pair-ethernet) Not all at once though, for example 1 GBit/s is only up to a distance of 40 meters. There's going to be some interdependence on those three stats that depend on the transmitter, receiver, and cabling quality. So there will probably still be 8-conductor Ethernet cabling for high speed + long distance configurations. In fact, when you look at the expected customer base from Harting, there's a lot of infrastructure, robotics/automation, and monitoring, but no home or office computing.
The biggest customer right now for SPE is industrial automation - basically getting factories all wired over IoT. (https://www.single-pair-ethernet.com/en/applications) Factories don't want to depend on a wireless network - heck we don't even rely on WiFi when streaming our video show. SPE could be a nice upgrade from CAN (https://en.wikipedia.org/wiki/CAN_bus) where you're still using 2 wires, but you get the benefit of Internet compatibility. We think another group of products that will be popular with SPE is IP cameras, especially once one big vendor makes SPE products. Every facility has dozens of security cameras, and by definition they're going to be really spread out over the building and grounds. That means the powering and wiring is going to be really annoying. With SPE, you can get power and data anywhere, over long distances.
Another really nice thing that SPE consortium came up with - you know how that little tab on the RJ-45 cable always breaks off? The connectors for SPE range from basic to waterproof varieties, and all of them are designed for secure latching with durable metal tabs!
Cool stuff to check out, specially for engineers working in automation and industrial technology, you'll want to take a peek at the SPE specifications. There's many companies that are part of the SPE design specification, so you can be confident it will be a well-supported new spec.
Get started by picking up some cables and connectors at Digi-Key so that you can design SPE into your next product: visit https://www.digikey.com/short/zrvt71 to order Harting SPE connectors and have them in hand tomorrow!

Full tutorial: https://learn.adafruit.com/epoxy-resin-torch-lamp-with-touch-control-3d-printed-base/
Make your own custom Minecraft-inspired Torch lamp from epoxy resin. Embed a strand of fairy lights inside, and set it on top of a Circuit Playground Express. The onboard NeoPixel lights provide a lovely, flickery torch effect. This gorgeous lamp glows from the inside out.
Add a piece of shiny copper tape to the base, and you can change light modes with a touch of your finger. Capacitive touch control is just like magic!
We've provided a simple 3d printable base model, or you can get creative and design your own display mount. We made ours look like Viking Dragon Ships to go with our Dragon Wall Sconce, and now we sail into sleep at night with fiery dragonish gargoyles watching over us.
Difficulty
Electronics Build: Easy This is a great beginner project if you're new to electronics. The wiring is really simple, and there's no soldering required.
Software / Coding: Easy We've provided code you can drag-and-drop to program your Circuit Playground using MakeCode, Microsoft's free online coding program. It's easy to customize our code or come up with your own.
Physical Build: Challenging Making the resin block is the hardest part of this project. There are a lot of ways it can go wrong, and epoxy resin can get expensive when your first or second pour doesn't go right.
On the other hand, it's really satisfying when it does go right, and you can create something that catches light - and people's eyes - like nothing else.Visit the Adafruit shop online - http://www.adafruit.com

The BAD APPLE demo looks great on these sharp memory displays - the contrast really shows well! We used a 128x64 video and scaled it up 3x to the 400x240 sharp display, that's why its a little blocky. Looks fab with a nice fast refresh - its the same display in the Playdate handheld game.

Grayscale OLED STEMMA QT display breakout
Workin' on a prototype - this one is for a 128x128 Grayscale OLED display. You do need a bunch of ram cause its 4bpp * 128 * 128 = 8K of RAM to buffer the whole thing - but one of our Feathers or Itsy's are happy to do that for ya. You can use I2C with STEMMA QT or SPI. This prototype has a common mistake ... it happens! Another revision and this should be good to go.

Our pixel dust library for Arduino was an easy port to these RGB matrices - this is a 32 x 64 matrix with a Feather M4 + RGB Matrix Featherwing for easy wiring. An accelerometer is used to determine the tilt and then some particle physics math draws the pixels as if they were reacting to gravity. Also looks nice with some black LED acrylic on top!

Today we're trying out some pneumatics! These are air-pumps and valves that allow folks to make inflatable project. We start with a pump that pushes air into a balloon thru an open valve. Then we close the valve to verify the ballon stays inflated. Then we release the valve and the air empties out! Works great - usually its hard to find low cost parts for these kinds of projects so we're excited to get them into the adafruit shop soon.

This BNO080 chip is a lot like the popular BNO055 - it has built in sensor fusion and pops out quaternions for you ready made like a toaster strudel. We've found its super stable, and pretty easy to use! There's I2C and SPI support, our upcoming breakout has level shifting and everything to use it quickly. Bryan wrote a CircuitPython library so you'll be able to use it on any board. But how to test it out? Quaternions are not human-readable, so we're gonna use Melissa's awesome 3D model viewer, it reads quats over Web Serial and spins a bunny model around! Gooooo bunny!

4" DPI Display HAT progress
This project is somewhat slow going (you can see it on my desk in this old video https://www.youtube.com/watch?v=zKv75lVAMsA) but we've gotten all the hand-wiring from this Raspberry Pi + DPI TFT display and turned it into a HAT. we have the display initializing and displaying - next up we have to tweak the sync signals, something seems to be a little bit off with them. We're so close! after that, we'll try adding a touch overlay. Display looks really nice though, so we're keeping on it!

This week's EYE on NPI takes a hint from the advice we're all getting to keep physically isolated - the ACS37002 current sensor (https://www.digikey.com/en/product-highlight/a/allegro-microsystems/acs37002-current-sensor) is a physically isolated sensor that takes advantage of the Hall effect to accurately measure power draw with full electrical isolation. Let's take a look!
The ACS37002 is a 400kHz fully integrated Hall-Effect current sensor with very high accuracy, making it ideal for use in control loops of the most demanding power conversion applications. Current flows through the internal conductor coupling the magnetic field generated to the Hall sensor IC. As a result of no physical connection between the current and the IC, high voltage isolation is achieved. The current is sensed differentially by two Hall plates that subtract out interfering external common-mode magnetic fields. The sensor is factory-trimmed to provide high accuracy over the entire operating range without the need for customer programming.
The sensor has an analog output and a reference output for signal integrity in noisy environments. A fast over-current fault output is included, having a user-configurable threshold via an analog input pin, providing short- circuit detection and enhanced system protection. The sensor also has four user-selectable gain options in the same device with two logic inputs without the need of extra components. This provides designers flexibility, and minimizes the overall bill-of-material for systems that need different current sensing ranges.
At some point in an engineer's life, they have to measure the voltage, current or power of a circuit - for example, to make sure the circuit doesn't have a short or open, to verify that a battery is charging, or to adjust motor torque. Measuring current can be a little challenging - we can use low side sensing, where we stick a small resistance at the bottom of our circuit, and amplify the voltage difference from ground. (https://learn.adafruit.com/portable-solar-charging-tracker/analog-stuff) That makes a ground differential, which is often undesirable. Or you can have high side sensing, where you measure the difference between the highest voltage and a resistor drop. Sometimes this is challenging because the device you're measuring is much higher voltage than the circuitry doing the measurements, and the high common-mode makes that difficult. Or maybe you're measuring AC or high voltages and you want to keep your circuit isolated for safety!
These Allegro current sensors are really nifty in that they are electrically isolated - there's no op amp connected to the sense resistor. How does this work? Instead of multiplying a voltage drop, we instead measure the magnetic field emitted by the current passing through the sense resistor. A hall effect sensor can measure the amount of field and then back-calculate the current passing by. This allow for very high voltage isolation. In the ACS37002 case, it's rated for 4.8kV isolation. Hall effect sensors are also very fast/responsive, so they can measure AC currents very easily, without introducing inductance like a current transformer would.
The ACS712 (https://www.digikey.com/products/en/sensors-transducers/current-sensors/525?k=ACS712) is a famous chip from Allegro that was released a few years ago and is very popular for robotics, home automation and other high current measurement applications (https://www.digikey.com/en/product-highlight/a/allegro-microsystems/current-sensor-ics). This new sensor improves on the ACS712 - there's a 3.3V version of the ACS37002, the internal resistance is lower, the non-linearity is half as much, there's an adjustable range pinstrap and the current range is much higher - up to 66A! There's also a lot more configuration options, with gain ranging from 200 mV/A to 33 mV/A. This chip would make a great upgrade when you want better performance and comes in an easy-to-use SOIC 16 package.
Want to upgrade your robot, scooter, or solar panel? You can order an ACS73002 today and have it in your hand tomorrow, pick a couple up today from Digi-Key stock by visiting https://www.digikey.com/short/zrb8p4

This week's EYE on NPI is super new and shiny - literally! This shiny gridded metal sheet (https://www.digikey.com/en/product-highlight/w/wurth-electronics/shieldiy-do-it-yourself-custom-shielding-cabinets) is a great new idea from Würth Elektronik (https://twitter.com/we_online), it's called ShielDIY and can be used to easily make custom RF shields or enclosures.
Würth Elektronik has created a do-it-yourself custom shielding cabinet kit, the ShielDIY. The ShielDIY kit is a fast prototyping solution for board level shielding cabinets. The kit is made up of nickel silver sheet with a thickness of 0.2 mm. The sheets feature lines carved every 5 mm for easy bending and cutting. To build a prototype, cut along the carved lines before bending to obtain the desired shape.
OK, this NPI is definitely one of those "OMG I didn't know that existed, now I need it" type items. If you're building sensitive or noisy projects, with lots of EMI from speakers, magnetics, motors, or RF, you probably know that a grounded metal cabinet will greatly help reduce electrical noise, you're building a little Faraday cage around your electronics! (https://en.wikipedia.org/wiki/Faraday_cage)
You see these on various products Digi-Key stocks, especially radio modules. For example, the Pi 4 has a metal tin around the WiFi chip section to help reduce emissions. (https://www.adafruit.com/product/4296). When you have a popular product, its easy to get a custom tin made. When you're prototyping or testing, especially at the RF stage, something like the ShielDIY can help you speed the process by letting you try different tin shapes and sizes.
The metal sheet has grid slices every 5mm so as long as you're cool with metric you should be able to make a wide range of sizes. Cut with metal snips or metal-friendly-scissors. You can then solder together the folded sides and solder the whole thing to the ground plane of your PCB. Super easy and effective!
If you do any RF testing, or RF work, you'll definitely want to have a sheet of this stuff in your toolbox for less than a Tubman. You can order from Digi-Key today and have it tomorrow! (https://www.digikey.com/product-detail/en/w-rth-elektronik/360002/732-360002-ND/10468233)

Full tutorial: https://learn.adafruit.com/ocean-epoxy-resin-lightbox-with-rgb-led-matrix-image-scroller
Explore the depths of your own personal ocean. Epoxy resin, alcohol inks, sand, and seashells come together to make a magical luminous ocean experience for your wall or desk. Each piece you create will come out unique, colorful, and beautiful.
The electronics assembly is pretty simple - the only soldering you'll need to do is stacking and assembling the Feather and FeatherWing. The LED matrix plugs into the FeatherWing and into the wall using connectors, so doesn't need to be soldered at all.
Epoxy resin is tricky by nature. Temperature, humidity, and dust need to be managed with any resin project. However, as resin projects go, I've found this to be about the easiest one I've ever done -- and also the hardest to mess up. Stray bubbles or dust motes in your resin actually add depth and interest to this particular project - more bubbles make the ocean waves look more realistic! And as you'll see, mixing and pouring all the pretty colors is incredibly satisfying.
The software and coding requires a little bit of setup if you haven't used CircuitPython before. Once you're set up, you can copy and paste our code and images or dig in and customize with your own artwork.

This week's EYE on NPI is going to the dogs ... Display Visions DOG Mini Graphic LCDs! (https://www.digikey.com/en/product-highlight/e/electronic-assembly-gmbh/compact-low-power-mini-graphic-lcd) You know we can't resist checking out new displays - we've always loved adding graphical interfaces to our projects and products.
From the Digi-Key highlights page: DISPLAY VISIONS' EA-DOGS102 series graphic LCDs are available in an FSTN positive transflective, STN negative transmissive, and FSTN positive reflective version. These displays have a 2.54 mm pitch and can be soldered directly or plugged into socket strips. Therefore, cumbersome gluing procedures, the need for designing a special mounting device, and error-prone cable connections that may lose contact are no longer a concern.
This LCD family was designed for use in German industry and will have an availability of 15+ years. The extremely efficient ratio of external dimensions to the active display area helps in designing very compact devices. Furthermore, its low-power use [single supply 2.5 V to 3.3 V (typically 250 µA)] makes it ideal for handheld applications.
We've seen some DOG displays before, they were used in the Pimoroni Display-o-Tron HAT (https://www.adafruit.com/product/2694) - you can tell these by their distinctive mounting style. Unlike common LCD modules which are pretty chunky (https://www.adafruit.com/product/1447), these are slim and svelte with direct mounting pins that are bonded onto the LCD glass so you can selective solder them without extra hand-labor.
Note that they don't come with back-lights by default - so if you want back-lighting you'll need to get separate LED modules. (https://www.digikey.com/product-detail/en/display-visions/EA-LED39X41-W/1481-1152-ND/4896791). These LCD's also don't have built in touch-screens, but you can get a resistive overlay to use like any other resistive touchscreen (https://www.digikey.com/product-detail/en/display-visions/EA-TOUCH102-1/1481-1201-ND/4896840)
These displays happen to have a UC1701 controller chip, for which we found a couple easy-to-use Arduino code libraries. (https://cse.google.com/cse?cx=008830049033802121810%3Azgsyidwem5w&q=uc1701) We loaded one of the u8g2 examples onto an ItsyBitsy and had it displaying in a few minutes! You just need SPI plus a few controller pins - no high voltage booster required.
There's a few options for display type, If you're not sure of which one you want, there's a little simulator application available from the EA website (https://www.lcd-module.com/treiber-tools-updates/tools.html) that lets you select different types (e.g. blue dye, black+white transflective) and backlight LEDs. There's also a few demo graphics you can use to gauge what text and graphics will look like on the display.
You can pick up these slim and easy-to-use displays at Digi-Key today for quick integration into your product (https://www.digikey.com/product-detail/en/display-visions/EA-DOGS102N-6/1481-1093-ND/4896732)
Taking a look at the new emboss feature recently added to Fusion 360. It's pretty boss! I made some examples of applying circular and rectangular patterns to embosses. Can we apply an emboss to a surface that has been embossed? Some limitations with self-intersecting and how to do tapered knurling.

This week's EYE ON NPI is buggin' out - with TDK Invensense's SmartBug Multi-Sensor Wireless Module! (https://www.digikey.com/en/product-highlight/i/invensense/smartbug-multi-sensor-wireless-module) Much like our recent product, the Adafruit CLUE (https://www.adafruit.com/product/4500) we're seeing more and more chip companies create 'showcase' hardware boards with a large number of sensors, and a wireless setup for quick demos. TDK did a particularly nice job on this one, its both adorable and powerful!
From the product description page: (https://www.digikey.com/en/product-highlight/i/invensense/smartbug-multi-sensor-wireless-module) This module combines six sensors, a powerful wireless (BLE) MCU, seven algorithm-driven features, and a rechargeable battery all in a small ladybug enclosure. It also comes with the option of an add-on board that includes a Wi-Fi module, an SD card slot, and an ultrasonic sensor from TDK.
It is the go-to module for quick and easy access to reliable and smart sensor data. The data from each sensor and algorithm can be accessed out-of-box without the need for any programming, soldering, or extra modifications. This makes it a perfect catalyst for IoT product developers, algorithm developers, and sensor data enthusiasts to better understand real application signatures, environment variations, and multi-sensor/algorithm behaviors.
I like that they went with a cute shape for this board, its a plastic ladybug, but is easy to open up with only 3 simple screws. Inside is a custom PCB with micro USB power/data, a Nordic nRF52840, 290mAh battery, and a whole mess-load of sensors. There's also an expansion port on the side, which you can use to plug in more sensors like a ToF range finder, two buttons, SD card storage and an ESP32 WiFi module. (https://www.digikey.com/product-detail/en/tdk-invensense/MD-42688-P-XB/1428-MD-42688-P-XB-ND/12525334)
The nRF52840 is the main processor, and provides the sensor connectivity, USB interface and of course Bluetooth LE - its one of our favorite processors, and hey it could be reprogrammed to run CircuitPython which would be super cool if someone made a board definition..hint, hint.
In the SmartBug is 5 sensors that cover motion and environment:
ICM-42688 triple axis accelerometer plus gyroscope (https://www.digikey.com/product-detail/en/tdk-invensense/ICM-42688-P/1428-ICM-42688-PCT-ND/11679713) ICP-10101 barometric pressure (https://www.digikey.com/product-detail/en/tdk-invensense/ICP-10101/1428-1143-1-ND/9555755) AK09940 triple-axis magnetometer (https://www.digikey.com/product-detail/en/akm-semiconductor-inc/AK09940/974-1191-1-ND/10231690) SHTC3 humidity + temperature sensor (https://www.digikey.com/product-detail/en/sensirion-ag/SHTC3/1649-1100-1-ND/8628149),
The real star quality of this product is the surprisingly well-done Windows 10 application. As you may know, Windows 10 added native BLE support, so it's possible to write desktop apps to communicate with sensors. You can find the app in the app store, so there's no popups warning you about running unknown apps. Once installed, you can run it, select BLE as the transport and connect in a jiffy.
The app has many nice features. The plotter is the first one we tried. It's exactly how you'd imagine, with selectable data rates - you can have multiple sensors at once. Next we tried the activity monitor - this one implements tap detection, plus pedometer/activity sensing using the IMU. What's nice is that since this board is wireless you can put it in your pocket to test the pedometer! Finally, we looked at the HVAC demo that uses the pressure sensor to detect when filters in an AC unit need replacing. I liked the realistic product demos here, for example I didn't realize that was a use case for pressure sensors.
TDK / InvenSense is famous for their IMU's - they're used in a wide range of motion-activated video game systems and VR such as the Nintendo Wii and Oculus Rift. (https://en.wikipedia.org/wiki/InvenSense) So it's no surprise they have a really sweet IMU demo showing of their fusion algorithms. These are now often built into the chips themselves, running a proprietary Kalman-like filter that will spit out quaternions or Euler angles. Again, this is a great demonstration of the wireless connectivity - you can pick up the ladybug and twist and twirl it around to see the rock-stable fusion output.
All in all, it's a nice bit of kit, at a good price! You can pick up a SmartBug at Digi-Key today, they have plenty of stock, and will ship it to you same day (https://www.digikey.com/product-detail/en/tdk-invensense/MD-42688-P/1428-MD-42688-P-ND/12525336)

This week's EYE on NPI focuses in on Infrared thermal sensing, a very 'hot' market right now (ha ha). Amphenol has just released a new low cost IR temperature sensor that is optimized for human temperature reading - the ZTP-148SRC1 (https://www.digikey.com/en/product-highlight/a/amphenol-advanced-sensors/ztp-148src1-non-contact-ir-temperature-sensor). Since one of the symptoms of Covid is fever, chances are you have gone to an office or store and had someone take your temperature using one of these very handy 'non contact' temperature sensors. (https://www.adafruit.com/product/4584) Unlike your classic glass or digital thermometers, these can give an instant reading, and no need to prod in someone's mouth or armpit. They're a little more complex, and cost more - but for rapid temperature taking, nothing compares!
These non-contact thermometers all consist of the same setup: an infrared temperature element, analog circuitry, microcontroller to read the analog signals and compute the temperature, LED or LCD display to show the measured temperature. For the last few months, its been nearly impossible to locate infrared temperature elements - either single or matrix style - they were immediately purchased as the demand for non-contact thermometers and thermal cameras skyrocketed. We were consigned to the quoted 50 week lead times until we saw this NPI on Digi-Key for a very low cost analog IR sensor with over 30K pieces in stock! (https://www.digikey.com/product-detail/en/amphenol-advanced-sensors/ZTP-148SRC1/45-ZTP-148SRC1-ND/12471481)
The idea behind these sensors is pretty simple. Every object in this world emits infrared energy as it heats up, and the infrared wavelength and magnitude change depending on the heat. The sensors contain a thermopile, a silicon sensor that increases in milli-voltage as more infrared energy is absorbed. Point the sensor at the object and it will measure that IR light, and with a little math and calibration we can back-calculate the temperature of the object. We use the same technique to measure the temperature of distant stars, pretty cool!
These sensors come in a cross-compatible package and configuration, although the packaging size may vary. They're in a metal tin with 4 leads. There are some more expensive sensors that contain a microcontroller with I2C control, and these pins would be power/ground/data/clock. However, these lower cost sensors are purely analog devices. Two pins are connected to a thermistor that is inside the can. The thermistor is used to compensate and correct for the internal temperature of the IR sensing element. The other two pins are for the thermopile, which is the actual infrared sensing element. The top of the cap is open and has a very thin layer of silicon glass which is transparent to Infrared but will block other light so you're only measuring what you want. Thermopiles are very sensitive and the voltage generated per degree is measured in tens of microvolts, so you definitely need a good op-amp for amplifying the voltage precisely to a level that is readable. Amphenol provides a schematic you can follow, and we also found tons of example projects and papers online (https://www.instructables.com/id/Thermopile-Sensor/) that use this part that you can follow along. Don't forget you'll also want to do 2-point calibration by pointing your sensor at known-temperature items so you can correct for any offset introduced by the op-amp or ADC.
You can pick up as many as your heart desires over at Digi-Key, just search for ZTP-148SRC on digikey.com or visit https://www.digikey.com/product-detail/en/amphenol-advanced-sensors/ZTP-148SRC1/45-ZTP-148SRC1-ND/12471481

This week's EYE ON NPI is a super exciting new Feather board that isn't from us! Alorium's Evo M51 (https://www.digikey.com/product-detail/en/alorium-technology-llc/EVO-M51/2003-EVOM51-ND/11689276) is an FPGA-enhanced embedded module featuring the Microchip SAMD51 32-bit Arm® Cortex®-M4 microcontroller alongside an Intel® MAX 10 FPGA. The Evo M51 board conforms to the Adafruit Feather specification for primary pinout, connectivity, and features - so you can use FeatherWings with this board to add WiFi, OLED or TFT displays, and more!
This Feather has a SAMD51 as a main microcontroller processor - we like this chip because it has a fast 120MHz Cortex M4 processor with lots of peripherals like I2C, SPI, UART, ADCs, DACs, lots of DMA, etc. Our Feather M4 features this chip, and it's one of our most popular Feathers (https://www.digikey.com/product-detail/en/adafruit-industries-llc/3857/1528-2648-ND/9553567) Alorium squished it down to a BGA package and used the left over space to wire up an Altera/Intel MAX 10 FPGA (https://www.digikey.com/product-detail/en/intel/10M25DAF256I7G/544-3538-ND/5429545) that can be programmed through the SAMD51 using a command line downloader.
By using a SAMD51, which we've supported for a while, this board comes automatically with Arduino and CircuitPython support - that makes programming easy and fast. On the other hand, when you need to get speed, connect to peripherals like cameras or HDMI displays, or perform exceptional calculations very fast...the FPGA is there to lend a hand. You can send messages between the EVO and SAMD51 using I2C or 10-bit parallel bus, so you can take advantage of the easy-to-integrate SAMD51 and the powerful-and-customizable FPGA. You get the best of both worlds!
Now, in order to pack so much into a Feather format, a few liberties were taken. For example, the classic 12/16 pin headers go to the SAMD51 and are compatible with FeatherWings. Then the FPGA pins are available on a collection of castellated pads. There's a 'EvoTray" add on board that you can solder the EVO M51 to in order to get breakouts for all the castellations.
Features Intel MAX 10 FPGA Microchip SAMD51 32-bit Arm Cortex-M4 microcontroller 512 KB Flash / 192 KB RAM 2 MB external Flash 55 digital I/Os 21 through-hole/castellated 34 additional castellated-only Six analog inputs Two analog outputs STEMMA QT (QWIIC Compatible) Feather footprint 0.9 inches x 2.2 inches Programmable with Arduino Designed for CircuitPython
Alorium is also a digital service provider for Intel/Altera FPGAs (https://www.digikey.com/en/design-services-providers/alorium-technology) so you can hire them to help out with your design or get it optimized for manufacturing.
Considering a single MAX10M25 is about $85 (https://www.digikey.com/product-detail/en/intel/10M25DAF256I7G/544-3538-ND/5429545) per, getting an EVO M51 (https://www.digikey.com/product-detail/en/alorium-technology-llc/EVO-M51/2003-EVOM51-ND/11689276) fully assembled AND with a co-processor AND Arduino/CircuitPython support AND video tutorials for $97 - its a great deal. If Digi-Key is out of stock, you can backorder it and they'll get you one ASAP - being an NPI there's not a ton of stock right now.
Visit https://www.digikey.com/product-detail/en/alorium-technology-llc/EVO-M51/2003-EVOM51-ND/11689276 to order your EVO M51 FPGA Feather today!

This updated version of the Overwatch Lucio Sonic Amplifier circuit and code uses CircuitPython running on a Feather M4, the Propmaker FeatherWing and three small additional amps. This makes everything simpler and smaller than the original which ran Arduino code on much more hardware.
The ability to play two streams of .mp3 files simultaneously inside of CircuitPython is a huge benefit!
LED Animation library makes it straightforward to run all of the different animations on rings, strips, and a jewel over a single data pin!

This week's EYE on NPI takes a look at a new kind of memory called MRAM - and some fresh new QSPI memory chips from Renesas that let you try out MRAM for your embedded projects! (https://www.digikey.com/en/product-highlight/r/renesas/m1000-m3000-series-mram) Memory and memory management is one of the trickiest challenges for an engineer, when it comes time to optimize power, speed and performance because you bump up against many of the restrictions different types of memory have - and the reason there's so many types of memory is cause there's no one perfect type of memory storage.
Just about every microcontroller has two kinds of storage - flash storage and RAM storage. RAM storage is just like the kind you have in your computer - except a few KB usually, instead of GB. RAM storage is pretty expensive, which is why a microcontroller that is only a few bucks has only a few KB. BUT RAM is really fast - you can read and write to any section of RAM within one or two instructions. There's one down-side to this speed - when the microcontroller is reset, or power is lost, the RAM is also lost.
For that reason, your microcontroller has the other kind of memory - flash - to store the program itself. Otherwise, your program would just disappear when you unplugged it (not good!). Flash memory is pretty inexpensive, so you usually get much more flash than RAM. Once in a while you also get microcontrollers that have a separate flash memory area, often referred to as EEPROM. Usually this is used for storing configurations, calibrations, identifiers, etc.
So normally, you've got non-volatile flash storage for code, volatile RAM storage for running the code, and maybe a smidge of EEPROM. Say you want to build a sensor data logger - you can't store the data in RAM, because you'll lose it when power is lost. You can't safely stick it in flash because that's where your code lives, and EEPROM is way too small. No problem, you can buy external non-volatile flash memory for microcontrollers! Again, for small amounts of storage, say less than 64K you can get low cost I2C EEPROM (https://www.digikey.com/products/en/integrated-circuits-ics/memory/774?k=i2c%20eeprom).
There's one big downside though - while these SPI flash chips have great non-volatility, they have an annoying problem that when you want to change data in a block you have to erase that whole block first, then write the new changed data - and a block is 4KB to 16KB! And erasing takes at least a few milliseconds, if not longer. Same with SD cards by the way.
THUS this week's EYE on NPI is interesting to us because it introduces a new kind of memory we've never used before - MRAM for magnetic random access memory. Where as flash memory stores memory by saving a bit by storing charge on a MOSFET gate, MRAM stores it on a ferromagnetic particle that can changed from N to S polarity to store 1 or 0. The core of Avalanche’s STT-MRAM cell is a proprietary perpendicular magnetic tunnel junction (p-MTJ) element which includes including a magnetic fixed layer, a dielectric barrier layer and a changeable ferromagnetic storage layer. The magnetic orientation of the fixed layer is fixed during the manufacturing process. During a programming operation, the magnetic orientation of the storage layer is electrically switched from a parallel state (low resistance state “0”) to an antiparallel state (high resistance state “1”), or vice versa, depending on the current direction through the p-MTJ element. Two distinct resistance states can thus be realized for data storage and sensing. The structure of the p-MTJ element can be tailored for different performance specs and application needs. (http://www.avalanche-technology.com/technology/mram-technology/)
What's nice is that every bit/byte can be written or read at any time, no block erases, no delays! You can drive these chips with SPI or QSPI at 100+MHz and down to 1.8V. These chips will be more expensive than NV SRAM or FLASH, but when you need fast writes and reads without waits, these are a great option. Another nice bonus with MRAM is that it is naturally less susceptible to radiation bit-flips - something that folks working on cubesats are super experienced with as a bane of their existence - you send a microcontroller into LEO and the flash memory gets corrupted by high energy particles. While this part is not specifically rad-hard or space-ready, for DIY experimentation, its way way less expensive than official aerospace devices - as seen in the PyCubed dev board (https://circuitpython.org/board/pycubed_mram/)
These chips are pin-compatible with most other SPI flash you may have designed in, so it's easy to try out MRAM! Check out the chips on Digi-Key available in 8-SOIC package for easy prototyping!

This guide details how to make a double layered face mask with a terrycloth towel lining and a fabric cover, held on by elastic cord that loops over the ears. The center of the mask has an anti-fog-treated clear plastic window, so the folks around you can see your lips move. Whether you work with the hearing-impaired or just prefer seeing people's faces as they talk, this mask design will restore a lot of understanding to your interactions.
This is a no-sew guide -- we'll use E6800 glue to hold the pieces together. If you do have sewing skills, the same steps can be followed using a needle and thread or sewing machine.

This week on EYE on NPI, folks who have wanted us to cover more motor controllers will see we're taking a STEP in the right DIRECTION with the TMC2226-SA Ultra-Silent Stepper Motor Driver with Step/Direction (https://www.digikey.com/en/product-highlight/t/trinamic/tmc2226-sa-ultra-silent-stepper-motor-driver). There's a lot of makers of stepper motor drivers these days - which means that companies are innovating a lot to stay ahead of the competition. Trinamic's stepper drivers have some interesting features we haven't seen in other drivers. And the price is good too! Only about $1.60 in quantity. For folks who have used Trinamics before, the new TMC2226 has a larger TSSOP package with heat dissipation thermal pad, much lower RdsOn LS 170mΩ & HS 170mΩ (compare to TMC2208's LS 280mΩ & HS 290mΩ) so that it can handle 2.8A current peak & 2A RMS (compare to TMC2208's 2A peak & 1.4A RMS) so this will be a very nice upgrade for CNC machines that need more drive!
The big thing Trinamic promotes with their stepper technology is their "StealthChop2" silent motor operation. Those who have played with stepper motors know that once you start microstepping them to get more precision, you also can get some interesting squeaks. That's because the frequencies used to microstep cause the motor coils vibrate to vibrate in the audible 20-20KHz range. These drivers change around the chopping frequency to keep the motor silent - They even have a cool "No Loud Stepper" icon!
The next big unique thing about this chip family is that there are three modes you can use with this driver.
The first one is 'legacy step/dir mode'. Nearly all stepper drivers have the same compatible-ish interface. You have a few power pins, a few ground pins, two to four pins for setting the microsteps-per-step, maybe some current feedback pins, and a DIR pin for direction and STEP pin that is toggled to step the motor forward or backward. The same is available on this chip, each step can be a fullstep or a microstep, in which there are 8, 16, 32, 64 microsteps per toggle. If you have an existing CNC design that you don't want to rework, then this mode is the easiest - you simply control the gpio with any 3 or 5V logic microcontroller
The second mode is an 'assisted step/dir mode' that uses internal one-time-programmable EEPROM to set up custom configurations such as turning on the internal sense resistors instead of using external ones in the OTP. The EEPROM is programmed over UART which we'll chat about next.
The third mode is most interesting, there's a hardware simplex UART connection for register you can use to control up to 4 motor drivers. There's a 2-pin addressing scheme so you can use the same UART for all 4 chips. This way you can set and read all sorts of registers such as doubling up the step detection so you get a step on rising and falling edge instead of per pulse, detecting a stalled motor, or changing the over-temperature protection thresholds. You can even do things like trigger multiple steps in a row with a given velocity in a free-run mode so you don't need to trigger the step pin at all.
With high-current capability, wide voltage range, 8/16/32/64 microstepping, and all these nice extras at the same price as the competition, this chip makes for a great driver for your mechatronic project or product! To help you get started, Trinamic has published ready-to-go KiCad dev board files. This is a rarity: usually you don't get an open source layout tool files.

This features emojis from Circuit Playground and works just like a fruit style slot machine. The handle is 3D printed and features a print-in-place spring loaded mechanism. The display is powered by an Adafruit Feather and the RGB Matrix FeatherWing. It also has a speaker and amp for playing MP3s. Using CircuitPython you can quickly show text, bitmaps, and animations on a number of different RGB Matrices.

Full tutorial: https://learn.adafruit.com/no-solder-papercraft-crystal-light-strand
These crystal gemstones are made from iridescent cellophane wrap (from the craft store, like you find in fancy gift baskets) that has been crinkled up and then run through a laminating machine. They can be cut by hand with a utility knife, or cut out on a vinyl cutting machine like a Cricut or Silhouette.
Then they are folded into shape, tab-in-slot style, and finally we add a small piece of iridescent cellophane inside to mimic the crystalline occlusions. This is surprisingly convincing -- they look like the real thing, but are light and flexible -- perfect for cosplay applications or just stringing up around the house.
The crystal patterns in this guide are designed to slot perfectly around Adafruit's NeoPixel Dot strand. Each strand has 20 lights, and we've included crystal patterns in varying shapes and sizes, so you can customize the look of your strand.

New tutorials on the Adafruit Learning System: http://learn.adafruit.com/
This week's EYE on NPI features a product I've been looking for - a USB Type C connector that is designed for power-only applications. CUI just released one, with a nice SMT/THM mixed package that's easy to solder and rework... and the price is nice! (https://www.digikey.com/en/product-highlight/c/cui-devices/power-only-usb-type-c-receptacle) (https://www.digikey.com/product-detail/en/cui-devices/UJC-HP-3-SMT-TR/2223-UJC-HP-3-SMT-CT-ND/12173367)
As an ideal solution for power only applications, CUI Devices’ UJC-HP-3-SMT-TR is a 6-pin USB Type-C receptacle delivering up to 60 W of power with a 3 A current rating and 20 VDC voltage rating. Housed in a surface-mount package, this USB Type-C connector removes the data transfer pins to create a more cost-effective option for designs where power or charging is the sole function. The UJC-HP-3-SMT-TR is further compatible with standard USB Type-C plugs, taking the accessibility and simplified design integration of the widely adopted Type-C connection and applying it to power-only applications.
USB Type C is a very capable & advanced interconnect system that has connector, cable, signal and software specifications. USB C is defined by a specific shape of USB connector and was designed to take that universality a step further by being the one connector for almost anything including data, power/charging, video and audio. The connector is also reversible, it has no up or down orientation!
While USB C does make some things a lot easier, there is also lots of confusion and uncertainty surrounding it. There are different voltages and current limits, and a TON of pins - XKCD even made fun of the complex Type C pinout in a recent comic (https://xkcd.com/2317) For most folks who have only recently gotten a handle on the complexities of USB with 4 pins and differential signaling, the 24 pins of Type C can be a little scary.
The connectors are also significantly more expensive and difficult to solder - 24 pins in a reversible case is a lot of pins! For example here is a full-pin version of the same connector style (https://www.digikey.com/product-detail/en/molex/1054500101/WM12856CT-ND/5843891) Its about $1.25 in quantity and has pins underneath the connector! Now compare that to this connector (https://www.digikey.com/product-detail/en/cui-devices/UJC-HP-3-SMT-TR/2223-UJC-HP-3-SMT-CT-ND/12173367) which is under $0.50 in quantity. That's a big BOM cost change! Of course, its less expensive because of the simpler contact structure - that trade-off means you can only use this connector for power applications, there are no USB data lines at all!
The only lines that are available are VBUS, GND, and the CC1 and CC2 lines. Don't leave those CC lines floating! They are required for setting the voltage/current draw of the sink. Use two 5.1K resistors from each pin to ground to indicate a 5V. A common misunderstanding is that you can use one resistor - nope! This way the device clearly defines itself as a 5V sink.
You can pick these fine connectors by the reel-full over at Digi-Key - search for part number 2223-UJC-HP-3-SMT-CT-ND (https://www.digikey.com/product-detail/en/cui-devices/UJC-HP-3-SMT-TR/2223-UJC-HP-3-SMT-CT-ND/12173367)

This updated version of the Lucio Sonic Amplifier circuit and code uses CircuitPython running on a Feather M4, the Propmaker FeatherWing and three small additional amps. This makes everything simpler and smaller than the original which ran Arduino code on much more hardware.
The ability to play two streams of .mp3 files simultaneously inside of CircuitPython is a huge benefit!

This weeks' EYE on NPI is more like EYE to the SKY, as we feature u-blox's low cost GNSS RTK eval/application boards. Digi-Key has plenty of stock of u-blox ZED-F9P eval boards (https://www.digikey.com/en/product-highlight/u/u-blox/c099-f9p-application-board), which are a fully-featured RTK application boards with a GNSS RTK module, WiFi module, Arduino-compatible headers, multiple power options including LiPoly charging, and easy-to-use configuration software. The price is under $250, bringing a multi-node RTK setup within many engineer's budgets. (https://www.digikey.com/product-detail/en/u-blox/C099-F9P-2/672-1110-ND/9817935)
RTK is a pretty interesting technology that has developed over the last few years, but even we had to do some research to understand it. GNSS stands for Global Navigation Satelite System, which for most people is synonymous with GPS - the American GNSS. There are some other, newer, GNSS's like GLONASS (Russian) and Galileo (EU).
Now, GPS and GNSS receivers are super common and inexpensive, you can pick up a fully-integrated GPS module like the SAM-M8Q (https://www.digikey.com/product-detail/en/u-blox/SAM-M8Q-0-10/672-1054-2-ND/7393574) for about $13, it even comes with an tuned path antenna. These little receivers work very well for outdoor location identification, and they work anywhere in the world. There is one drawback that folks bump into when using GNSS - and that is the precision of location. Even if you are in the middle of a field, and you've got a perfect view of the clear sky, GNSS accuracy is around 3 meters / 10 feet. Which is pretty good for a $13 module, and for general navigation and asset tracking, 10 feet is a fair tradeoff.
For some applications, like autonomous cars or agricultural equipment, surveying, or drones - 10 feet won't cut it. If the location is jumping around, it could cause the machinery to veer off course, smashing into a building or cliff or human! For these high-tech use cases, we need to boost the GPS accuracy and precision, which we can do by adding RTK.
RTK stands for Real Time Kinematics, a way of precisely determining location and orientation ... in real time! How it works is pretty amazing. We already know how GNSS works - by getting timecoded signals from 3 or more satellites that circle the globe and comparing the time code deltas, we can triangulate where were are approximately on earth. Now say we have two GNSS receivers somewhat close to each other, say within a mile. Each one is going to receive pretty similar signals, and will see the same satellites. The receivers can then perform calculations on the phase of the same signal they received, and compare the differences between them. The differences will be incredibly slight, and the measurement requires good quality sensing, because we're measuring the signal of a 1.5GHz transmission from literally space. That precision sensing is why the price of RTK has historically been in the thousands of $ to get a setup, especially since you need one base station and one+ rovers. Thanks to u-blox's engineering and market skill, they've gotten a full development kit that can be used as a standalone base station or rover for under $250! (https://www.digikey.com/product-detail/en/u-blox/C099-F9P-2/672-1110-ND/9817935)
But, if you're aware of how to best use RTK, there's some amazing use cases that have been waiting for this kind of precision orientation and tracking capability. So, if you've ever wanted to play with RTK, there's no better application board to start with, and you can pick one up today at Digi-Key, just search for 672-1110-ND on digikey.com
Don't forget you'll need two boards (unless there happens to be a public RTK base station somewhere nearby you). Then, once you're ready to integrate the ZED-F9P into your development platform, you can pick modules up at Digi-Key as well! (https://www.digikey.com/product-detail/en/u-blox/ZED-F9P-00B-02/672-1212-1-ND/9990023)

We made a BLACK LIVES MATTER light up protest sign for night time use that works and looks great using a 64x32 RGB LED Matrix, Adafruit Feather, and CircuitPython.
These panels are normally used to make video walls, here in New York we see them on the sides of busses and bus stops, to display animations or short video clips. You can make them portable and informative.
The matrix can also display the names of Black people killed by the police which the Washington Post compiled in to a database which is a datasource on GitHub. See: saytheirnames.glitch.me

New tutorials on the Adafruit Learning System: http://learn.adafruit.com/
We've spend a lot of EYE ON NPI weeks on the niftiest sensors, microcontrollers, and wireless eval boards. But every engineer knows that your design can have the coolest tech in it, and then fail because of a bad mechanical connection. Cabling and connectors are not as sexy as a Bluetooth chip, but they are essential to any design - and a poor quality cable may not fail for weeks or months, bringing the whole product down for want of a single bad crimp!
That's why we were psyched to see this new service from Digi-Key and Molex (a juggernaut in the connector industry!) called Molex Custom Cable Creator. (https://www.digikey.com/en/product-highlight/m/molex/custom-cable-creator). This is awesome because there's a frustrating 'dead zone' in cable needs, where you can't use an off the shelf cable, and you're not ready to have a cable factory make 10,000 pieces. Even for only a single cable, crimping and crafting cables is a challenge (say that 5 times fast!). You have to have the right crimp tool, which can be surprisingly expensive and difficult to use, and you have to be super careful not to nick the wires - where strain can build and crack the wire when moved.
The Molex Cable Creator allows users to choose from many different product connector families, circuit sizes, wire gauges, UL styles, cable lengths and more. To meet the needs of unique applications, the proprietary pinout configurator provides options to select individual connections and wire color.
Popular Molex series like Pico Blade, Micro-Fit, Mini-Fit, Milli-Grid, Pico Clasp, Nano-Fit, Ultra-Fit, KK 254, DuraClik, Mega-Fit, Clikmate and so many more Custom Cables can be created by your request. The new Custom Cable Creator is a revolutionary tool poised to dramatically help wiring harness designers develop solutions to meet their exact needs. The amount of customization now available, customers can easily design their own pinout for the wires and greatly simplify cable routing and management.
Let's go through the process ourselves. First up visit the Custom Cable Creator here (https://www.molex.com/molex/custom-cable-creator/digikey/) We're going to make a matching connector for a barcode scanner we stock on Adafruit (https://www.adafruit.com/product/1203). The scanner connects using an 11 pin Molex cable with PicoBlade connector - 1.25mm pitch.
Start by selecting the Side A connector, there's over a dozen choices from 6.7mm pitch down to 1.0mm pitch. We picked PicoBlade 1.25mm. Then select the number of rows and circuits - in this case single row, 11 circuits. You can pick the cable end type, either receptacle or plug. In this case we want a receptacle so it plugs into the scanner. The image will update based on your choice so you have a good sense of what you've got selected!
Next, pick the cable length and wire gauge. I want a cable about 6" long, that's 150mm. The scanner doesn't draw a lot of power so 28 AWG is fine, that will make it flexible.
Onto the other side of the cable - since the wire gauge was set in the previous step, you can't go with any connector you please - only some will let you connect the gauge wires. Another option is...no connector! Say you want to solder this to a perfboard, choose "Single ended" to get bare wires at the end. In this case, I want to connect the 4 USB pin wires to my single board computer. The connector will fit into 0.1" header so I choose KK 254 which gives me a 0.1" receptacle at the end. In this case I want 4 circuits for the 4 data pins
Here is also where you pick pinout configuration and cable colors. Since we're only using 4 wires, we want to make sure they're inserted into the right slots. In this case, we'll be populating slots 1 through 4. I'll set the colors to match the USB standard, that's always a nice touch.
To wrap up, pun intended, we pick the cable bundling or wrap. I would do these for thicker cables, woven braid in particular is my favorite kind of covering!
Now we finish placing the order. Cables are super customized so the sample cost won't be automatically calculated. Someone will email you to complete the order and pricing for a sample and then for larger quantities.
If you don't need a complex cable, there may be an off-the shelf one available. Check out the cable assemblies category on Digi-Key for a wide range of pre-made cables (https://www.digikey.com/products/en/cable-assemblies/21), we've definitely used the assembled IDC cables for quick inter-board connects. If you're not a fan of wire crimping, you can get pre-crimped wires for standard Molex connectors, in a variety of colors and lengths. (https://www.digikey.com/products/en?keywords=wm12450) The only thing is that you'll get the same crimp on both sides in most cases.

This week's EYE on NPI is on a super super fresh NPI that we're excited about - the ST VL53L3CX (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/vl53l3cx-time-of-flight-ranging-sensor) which is the latest version of the 'micro-LIDAR' sensors from ST. Starting with the VL6180X, and continuing to the VL53L0X and VL53L1X, these sensors are really amazing - they have a tiny laser that emits light and is bounced off nearby objects to determine the distance. The sensor has extra-ordinary timing sensing so it can measure the 'time of flight' between the photos emitted by the laser, and when it arrives bounced back. Thus, they are called "Time of Flight / ToF" sensors.
VL53L3CX ToF product from STMicroelectronics embeds ST’s third-generation FlightSense patented technology. It combines a high-performance proximity and ranging sensor with multi-target distance measurements and automatic smudge correction. The miniature reflowable package integrates a single-photon avalanche diode (SPAD) array and physical infrared filters to achieve the best ranging performance in various ambient lighting conditions, with a wide range of cover glass windows.
There's a lot of ways to measure distance - often folks use IR sensors, these bounce Infrared LED light off an object and measure the amount of light detected. These are really inexpensive and simple to use - you just need an analog reading of the phototransistor voltage, but have a few downsides: the readings are not precise distances, the sensor often have short ranges (usually maxing out at 150cm), and the color and reflectivity of the sensed object affects readings. Darker objects absorb more of the IR so seem to be 'farther', this can cause frustration as seen in this popular video showing different folks trying to use a soap dispenser with IR sensing: lighter skin works, darker skin does not trigger the distance sensor. (https://twitter.com/nke_ise/status/897756900753891328). Ultrasonic is another popular distance measurement, but its slower - relying on sound travel - and is very bulky since you need a transducer. You also can't have anything blocking the transducer. As we mentioned, the VL53L3CX is the latest in this family (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/vl53l3cx-time-of-flight-ranging-sensor) which started with the VL6180X and has grown since. This new chip is the same size and pinout as the previous VL53Lx chips so it should be an easy update. The nifty new capability in this sensor is that it can now track up to 4 objects distances at a time, instead of a single distance. Here are the specs:
Long distance and accurate ranging up to 3 m Excellent short distance linearity ST histogram algorithms allow multi-target distance measurement and cover glass crosstalk immunity beyond 80 cm ST algorithms enable dynamic smudge compensation Very small package for easy integration (single module combining laser emitter, SPAD receiving array, and micro-controller in a reflowable package) Can be hidden behind various cover window material and colors (Creative ID) Not affected by target reflectance, material and color, or unlikely traditional IR proximity sensors
These chips are super fresh, but you can use our existing EagleCAD design to create your own eval board. (https://github.com/adafruit/Adafruit-VL53L0X-ToF-Distance-Sensor-PCB) There's a reel of chips available at Digi-Key for you to purchase right now!
You can find them at part number 497-VL53L3CXV0DH-1CT-ND (https://www.digikey.com/product-detail/en/stmicroelectronics/VL53L3CXV0DH-1/497-VL53L3CXV0DH-1CT-ND/11658314)

From the Desk of Ladyada - The Great Search at Digi-Key. A new feature on Desk of Ladyada, we're still searching for the best name :)
On our first episode of The Great Search with Digi-Key we go hunting for an inductor! Boost converters are ultra-integrated these days, so other than a few resistors and capacitors, we only need to spec out the power inductor. It's important to pick the right one - small enough to fit on the PCB, with enough current carrying capacity for our boosting, and low DC resistance for high efficiency! Join us as we show how to whittle down the thousands of available inductors to a few choice options.

Product link: https://www.digikey.com/product-detail/en/texas-instruments/CC2652RB1FRGZR/296-CC2652RB1FRGZRCT-ND/11502644
This week's EYE on NPI is a family of fresh wireless microcontrollers from TI that recently got a cute new update. The CC2652RB is the latest addition to the CC2652/CC1352 family, which a cool twist: there's no external crystals required for this 2.4GHz radio, the built in oscillator is temperature compensated and precise enough to keep the radio tuned! (https://www.digikey.com/en/product-highlight/t/texas-instruments/cc2652rb-simplelink-wireless-mcu) While researching it, I ended up looking up the rest of the family, so let's introduce them.The CC2652RB is the latest iteration of the CC2652R (https://www.digikey.com/product-detail/en/texas-instruments/CC2652RB1FRGZR/296-CC2652RB1FRGZRCT-ND/11502644), which is the little sister to the CC1352R (https://www.digikey.com/product-detail/en/texas-instruments/CC1352R1F3RGZR/296-CC1352R1F3RGZRCT-ND/10435240). These are part of the TI SimpleLink wireless family of chips - combining a Cortex M4 main processor with a wireless radio subprocessor, in one chip, for ultra-small and ultra-integrated wireless devices. TI has been developing chips in the CC wireless family for years, and they have a substantial segment of the market for WiFi, BLE, ZigBee, sub-GHz, etc. SimpleLink wireless is TI's API/IDE that builds on the MSP43x series of microcontrollers with wireless hardware tacked on so you can reuse the main application code, while changing the underlying protocol and transport. This is handy for IoT products because its common to design a product for WiFi or ZigBee and then release a version that is BLE. We have a video all about IoT protocols and transports if you'd like to familiarize yourself with the design decisions and trade-offs you'll face (https://learn.adafruit.com/alltheiot-transports)Let's check out the deets on this microcontroller set:
Texas Instruments' CC2652RB SimpleLink multiprotocol 2.4 GHz wireless crystal-less MCU with integrated TI bulk acoustic wave (BAW) resonator technology supporting Thread, Zigbee®, Bluetooth® 5.1 low energy, IEEE 802.15.4, IPv6-enabled smart objects (6LoWPAN), proprietary systems including the TI 15.4-Stack (2.4 GHz), and concurrent multiprotocol operation through the dynamic multiprotocol manager (DMM) software driver.

Full Tutorial: https://learn.adafruit.com/make-it-glow-how-to-solder-neopixels-a-beginners-guide/overview
This guide is for beginners who are ready to take the next step in DIY electronics: putting that soldering iron to use to add NeoPixel or other addressable LED lights to your project.
You don't have to be able to solder to use NeoPixels! Here is a beginner tutorial that shows how to use NeoPixels with no soldering:
https://learn.adafruit.com/make-it-glow-your-first-neopixel-project
However, there are times when soldering is really the best option. If you want to use NeoPixel rings, or individual pixels, or create more elaborate or complicated designs with multiple strips, there's really no way to do it without soldering.
The good news: it's not as hard as you think! There are a fair number of tools to acquire, but once you've got your station set up, a whole world of creative possibilities will open up for you.
In this guide, we'll recommend some tools and equipment that every DIY electronics maker should have in their workshop. Then, we'll go over the techniques and skills needed to get a good solder connection, and how to secure your connections it so they are sturdy and reliable.
Finally, we'll cover some techniques for repairing broken strips, and troubleshooting help for when your project just won't behave the way you want.

This week's EYE ON NPI (https://www.digikey.com/en/product-highlight/n/nxp-semi/i-mx-rt106l-local-command-voice-solution) looks at a new spin on a familiar favorite! We've chatted before about the IMX RT10xx series of chips from NXP. These 'cross-over' chips are Cortex M7's running at 500 or 600 MHz - that means you get the relative simplicity of a Cortex microcontroller with the speed and power of a microprocessor. Heck, the RT106x's ~3000 CoreMark @ 600 MHz makes it faster for some computations when you compare it to the Raspberry Pi Zero' ~2000 CoreMark (https://www.eembc.org/coremark/view.php?benchmark_seq=2534) - most of that due to the Linux operating system overhead. This chip family recently made its way into CircuitPython (https://circuitpython.org/board/imxrt1060_evk/) as we were super-excited to see such a powerful and low cost chip.
OK but back to this week's EYE ON NPI which is a sister-chip, the iMX RT106L (https://www.digikey.com/en/product-highlight/n/nxp-semi/i-mx-rt106l-local-command-voice-solution) - an interesting twist to the RT1060 - this chip is licensed to use with a wake-word + voice-activation software stack. It seems like the hardware is the same, and share the same datasheets and reference manuals. So it's more about purchasing hardware that has a licensing cost baked in - this reminds us of when we would purchase MP3 chips that had a 50 cent licensing fee built in. (https://blog.adafruit.com/2017/04/18/is-mp3-now-patent-free-makerbusiness-technicolor/)
So, why is this interesting? Well, you've seen the proliferation of voice assistants like Siri, Google Voice and Alexa - they all use a a microcomputer, with a very powerful processor, to record audio and send it to the cloud for processing. Having to build a full computer with operating system to do voice control makes the BoM cost go up - you need a few MB of RAM, plenty of flash, a complex PMIC...what if we could do all of the processing on a really fast microcontroller instead? Like...a 600 MHz M7? Yes!
NXP’s MCU-based solution for local voice control leverages the i.MX RT106L crossover MCU, enabling developers to quickly and easily add local voice commands to their products. The ultra-small form-factor, production-ready hardware design comes with fully integrated software that runs on FreeRTOS for quick, out-of-the-box evaluation and proof-of-concept development. This turnkey solution minimizes time-to-market, risk, and development effort, enabling OEMs to easily add voice to their smart home and smart appliance products without the need for Wi-Fi and cloud connectivity while also addressing the privacy concerns of many consumers.
There's a few different products in this family. First is the 106L - the L for "Local". (https://www.digikey.com/products/en/integrated-circuits-ics/embedded-microcontrollers/685?k=rt106l) That's internet-less voice command inference. Good for maybe a dozen words. There's a collection of words built-in - for more words you'll have to train up the engine which is a non-trivial task. The Local is great for simple device control and no WiFi is required so its very low power and low cost. Next is the similar 106A, the A is "Alexa", as you may guess it has Amazon Alexa software ready to go to create custom Alexa-connected devices. (https://www.digikey.com/product-detail/en/nxp-usa-inc/MIMXRT106ADVL6A/568-MIMXRT106ADVL6A-ND/10816229) You'll need to use/add WiFi for the cloud backend communication. Digi-Key has a great tutorial/article about the Alexa series and the nitty-gritty detail of how it works over here (https://www.digikey.com/en/articles/quickly-implement-alexa-built-in-iot-designs)
Lastly is the 106F where F is for "Face" - yes facial recognition! (https://www.digikey.com/products/en/integrated-circuits-ics/embedded-microcontrollers/685?k=rt106f) This version connects up to a camera and can be used to recognize faces.
These are all interesting machine learning demos many of us have seen, and its interesting to see NXP integrate them as software 'add-on's for a very powerful and capable chip. Note that the RT1060 doesn't have hardware ML acceleration or co-processor, so you'll be relying on the speed and power of the microcontroller itself. We think in the next few years we will see similar "AI ready" chips that are even less expensive thanks to a neural-net accelerator. Meanwhile, if you want to explore these powerful chips, you can check out the entire NXP iMX RT series chip collection here on Digi-Key (https://www.digikey.com/en/product-highlight/n/nxp-semi/imx-rt-series)
And pick up the iMX RT106L eval kit here on Digi-Key (part 568-SLN-LOCAL-IOT-ND ) so you can start playing with local voice recognition: order today and you'll have it tomorrow! (https://www.digikey.com/products/en/development-boards-kits-programmers/evaluation-boards-embedded-mcu-dsp/786?k=rt106l)

https://hackaday.io/messages/room/2369
After being announced in September of 2019, the ESP32-S2 is finally making it into hobbyist's hands. On the face of it, the S2 seems less capable than the ESP32, with a single core and no Bluetooth or Ethernet. But the S2 more than makes up for that with a much faster CPU, scads more GPIO, more ADCs, a RISC-V co-processor, native USB, and the promise of very low current draw. It could be that the ESP32-S2 proves to be even more popular as it becomes established.
To talk us through the new chip's potential, Limor "Ladyada" Fried and Scott Shawcroft, both of Adafruit Industries, will join us on the Hack Chat. Come along and learn everything you need to know about the ESP32-S2, and how to put it to work for you.
Join the Hack Chat and return this Wednesday at 12:00PM PDT with your questions!

This week's EYE ON NPI is a fairly new sensor from MAXIM called the MAX86150 (https://www.digikey.com/en/product-highlight/m/maxim-integrated/max86150-integrated-ppg-and-ecg-biosensor-module).
We recently did a video where we took apart an off-the-shelf pulse oximeter (https://www.youtube.com/watch?v=ut7oGkIwRrE) and some folks have asked how they can build their own for learning about bio-sensing, or emergency use. We looked around and found in addition to the common MAX30102 (https://www.digikey.com/product-detail/en/maxim-integrated/MAX30102EFD/MAX30102EFD-ND/6166869), this MAX86150 (https://www.digikey.com/product-detail/en/maxim-integrated/MAX86150EFF-T/MAX86150EFF-TCT-ND/9839125) is a nice Integrated Photoplethysmogram and Electrocardiogram Bio-Sensor Module For Mobile Health. Phew, that's a lot of words, but what it means is that it's an optical sensor for pulse oximetry (https://en.wikipedia.org/wiki/Pulse_oximetry) with the addition of an EKG analog front end (https://en.wikipedia.org/wiki/Electrocardiography). This is pretty rare - usually there's one sensor to manage the optical blood-gas sensing and one to do the electrical heart activity sensing. Why both? For telemedicine or self-monitoring, it might be beneficial to see the electrical activity waveforms as well as the SpO2 measurements since they can signify different health issues.
The MAX86150 is an interesting chip in that it has a clear body for IR/Red LED emitting and sensing. Unlike most pulse oximeters we've seen, this does not shine light through the finger, it bounces the light off of the finger tip instead. This makes it a simpler wearable, although the cost is a little higher because of the high integration. One cute thing we noticed in the datasheet is that the sensor automatically detects when there's something in front of the optical sensor so that it will not keep blasting the high power LEDs, a nice power-saving trick!
The interface for this chip is I2C, so it's easy to use with just about any chipset. You set the sensor off to collect data and then read the waveform back out. The PPG data is processed by a 19-bit ADC, the EKG is 18-bit and a FIFO collects data in chunks so you can read it at your convenience. Note that the sensor is 1.8V power and logic - it's designed for low power wearables - so you will need level shifting circuitry for use with 5V or 3.3V microcontrollers & microcomputers.
Best of all, there's a super-sweet MAX86150 evaluation board (https://www.digikey.com/products/en/development-boards-kits-programmers/evaluation-boards-sensors/795?k=MAX86150) that even has the two 'dry' EKG electrodes you put your fingers over. The board is a FeatherWing, and even comes with a MAXIM Feather board, so you can make a portable BLE sensor.
If you want to order up some MAX86150, Digi-Key has tons in stock in both tray and cut tape (https://www.digikey.com/en/product-highlight/m/maxim-integrated/max86150-integrated-ppg-and-ecg-biosensor-module) - visit https://www.digikey.com/product-detail/en/maxim-integrated/MAX86150EFF/MAX86150EFF-ND/7392247 to order this sensor today!

This week's EYE on NPI looks at a new microcontroller series from ST Micro. Yes, last week was also an ST part - but this one popped into my NPI feed and I just thought it was so interesting, ST gets a double-header! The STM32L4P5 series of chips (https://www.digikey.com/products/en?keywords=%20%09STM32L4P5) looks like an excellent competitor to the Microchip ATSAMD51 (https://www.digikey.com/products/en?keywords=atsamd51) we use so often - with matching-or-better specifications. Let's take a closer look!
You can get more spec's about this chip over at ST's website (https://www.st.com/content/st_com/en/products/microcontrollers-microprocessors/stm32-32-bit-arm-cortex-mcus/stm32-ultra-low-power-mcus/stm32l4-plus-series/stm32l4p5-q5/stm32l4p5ce.html). Here's the overview:
The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all the Arm® single-precision data-processing instructions and all the data types. The Cortex-M4 core also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances the application’s security.
These devices offer two fast 12-bit ADCs (5 Msps), two comparators, two operational amplifiers, two DAC channels, an internal voltage reference buffer, a low-power RTC, two general-purpose 32-bit timers, two 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and two 16-bit low-power timers. The devices support two digital filters for external sigma delta modulators (DFSDMs). In addition, up to 24 capacitive sensing channels are available.
They also feature standard and advanced communication interfaces such as: four I2Cs, three SPIs, three USARTs, two UARTs and one low-power UART, two SAIs, two SDMMCs, one CAN, one USB OTG full-speed, one camera interface and one synchronous parallel data interface (PSSI).
In particular, we like some of the 'upgrades' we see compared to other chips - the roomy 320KB RAM, 5 MSPS 12-bit ADCs (that's the same as a basic pocket oscilloscope!), 9 x 16-bit timers, CAN bus (usually you have to upgrade to get CAN support!), built in op-amps, and... most interesting to me is a built in TFT manager! Not just parallel (6800/8080) style but the 'real' 24-bit TFT with HSYNC/VSYNC/CLK signals! Usually you have to go to a Cortex M7 to get something like that included (see the iMX RT or STM32H7 series for example). 24-bit TFT can be easily converted to VGA (using some resistors) or even HDMI using off-the shelf adapter chips (https://www.digikey.com/product-detail/en/adafruit-industries-llc/2219/1528-1452-ND/5761220) so it's really a neat thing to see.
True TFT output is a rarity because of the frame buffer you normally need. From what ST says in the datasheet the way this is managed in RAM is to have a 8-bit palette of 24-bit colors. So for a classic 4.3" TFT display (https://www.adafruit.com/product/1591) that is 480x272 pixels, that would mean 128KB of RAM to address all pixels. A 320x240 display would be only 75KB.
The LCD-TFT display controller provides a 24-bit parallel digital RGB (red, green, blue) and delivers all signals to interface directly to a broad range of LCD and TFT panels with the following features: • One display layer with dedicated FIFO (64 x 32-bit) • Color look-up table (CLUT) up to 256 colors (256 x 24-bit) per layer • Up to 8 input color formats selectable per layer • Flexible blending between two layers using alpha value (per pixel or constant) • Flexible programmable parameters for each layer • Color keying (transparency color) • Up to four programmable interrupt events
Right now there's only two packages available - a 144 LQFP STM32L4P5ZGT6 (https://www.digikey.com/product-detail/en/stmicroelectronics/STM32L4P5ZGT6/497-STM32L4P5ZGT6-ND/11590990) and a 169-BGA STM32L4P5AGI6P (https://www.digikey.com/product-detail/en/stmicroelectronics/STM32L4P5AGI6P/497-STM32L4P5AGI6P-ND/11591137) but according to the datasheet there will be 48, 64 and 100 pin variant QFN & QFP's.
For now we recommend picking up the STM32L4P5AGI6PU Discovery also known as STM32L4P5G-DK on Digi-Key (https://www.digikey.com/product-detail/en/stmicroelectronics/STM32L4P5G-DK/497-STM32L4P5G-DK-ND/11613090). Which has a built in debugger/programmer and is directly supported in STM32 Cube IDE.

This week's EYE ON NPI takes a closer look at security! The STSAFE chip collection from ST (https://www.digikey.com/product-detail/en/stmicroelectronics/X-NUCLEO-SAFEA1A/497-X-NUCLEO-SAFEA1A-ND/11568322) is a super easy and inexpensive way to add hardened security to your project - giving you a lot of flexibility when deciding on core chipsets.
Why is a separate chip important? Microcontrollers often store their code in flash memory, so even if you hard-code authentication keys in flash or EEPROM, it can be read out by dumping the firmware. Yes, even if you have a chip that has firmware-readback turned off, it’s possible to trick chips into revealing their secrets! As hackers ourselves, we've seen novel and effective techniques for unlocking microcontroller firmware that would normally be in State-actor's toolkits available at hobbyist costs. Techniques like epoxy-removal and pinpoint UV erasing, power glitching, bootloader buffer overflows, key brute-force guessing, decompilation, power-usage instruction tracking can be used to disable or circumvent firmware protection fuses.
In addition, many products are now embedded Linux computers running a plain filesystem with executables that cannot be secured. So, given that your microcontroller memory should not be considered a secure storage, you may want to consider using a secure element chip. These chips are designed to withstand many attacks and can be programmed with the private key at your factory. Then, the secrets never leave the secure chip. Instead of having a private key sit in microcontroller memory where it could be read out, data that needs to be authenticated or encrypted is sent back and forth through I2C. It’s a little extra BoM cost but is a nice way to keep the secrets in a lock-box.
We've seen these chips used for a variety of purposes - TLS handshake speed-up, firmware verification, device authentication, message signing and authentication, and of course secure-channel establishment. We teamed up with Digi-Key to make a video series to cover IoT security - best practices and techniques - which also covers secure chips so if you want a deep dive into IoT security check out this guide and video! (https://learn.adafruit.com/all-the-internet-of-things-episode-five-the-s-in-iot-is-for-security)
When sourcing a security chip, you want a trustworthy supplier who takes security seriously - the chips are not expensive, but you want to make sure the supply chain is accounted for. ST is a well known semiconductor company that we'd recommend and trust for any of our uses!
The STSAFE-A100 is a highly secure solution that acts as a secure element providing authentication and data management services to a local or remote host. It consists of a full turnkey solution with a secure operating system running on the latest generation of secure microcontrollers.
The STSAFE-A100 can be integrated in IoT (Internet of things) devices, smart-home, smart-city and industrial applications, consumer electronics devices, consumables and accessories.
If you want to get started with the STSAFE, you can pick up this handy board, it is Arduino-header compatible. You can plug it into an ST Nucleo dev board. In particular, the STM32L476RG is used for the X-CUBE example firmware so we recommend picking up a NUCLEO-L476RG as well (https://www.digikey.com/products/en/development-boards-kits-programmers/evaluation-boards-embedded-mcu-dsp/786?k=STM32L476RG). The ST dev boards are really affordable and come with a built-in debug/programming chipset for quick setup. Development is done in ST's IDE setup, if you've never used it before, please check out Shawn Hymel's excellent video series that takes you step by step through setting up to use STM32Cube IDE (https://www.digikey.com/en/maker/videos/shawn-hymel/getting-started-with-stm32-and-nucleo-part-1-introduction-to-stm32cubeide-and-blinky)

Here, we're using a flex sensor as part of a voltage divider circuit. A voltage divider outputs a percentage of the incoming voltage. In this case, one resistor is fixed, the other varies. As the sensor bends, its resistance increases, and the measured voltage decreases. When it is straightened, its resistance decreases, and the measured voltage increases.
This method is used in the Power Glove BLE MIDI project (learn guide coming soon) to read analog values with the Feather Sense board as the fingers are bent.

Create a wireless, gesture activated Bluetooth MIDI controller with a Nintendo Power Glove. Using CircuitPython running on a Feather Sense nRF52840 board, you can access the four finger flex sensors, as well as the Feather's accelerometer. Connect over BLE MIDI to a synthesizer, and then map CC (continuous controller) values to respond to gestures.

Adafruit Industries, Essential service and business: Critical Manufacturing, NYC – Executive Order 202.6 https://adafruit.com/covid
How to place an essential, COVID-19 related order at Adafruit https://adafruit.com/covidorders
This week's EYE ON NPI is a topical one - here at Adafruit we've been supplying essential services and goods for engineers, makers, doctors, and students all working on designing products and techniques to help folks with COVID-19. This is an amazing time to see so many talented and driven folks around the world all putting their talents to work!
Part of that design work is to have the device alarm a caretaker that something went wrong. For example, if you are designing a pulse oximeter or heart rate detector, you'll want to sound an alarm when the BPM or SpO2 dip below a safety threshold. You'll also need an alarm when power is lost, say if someone accidentally unplugged the power cord. When building DIY and IoT projects, a simple 3V buzzer or piezo might be enough - to let you know when the plants need watering, or if there might be rain tomorrow - but this is not enough for an industrial or safety device, especially one being used in a loud environment.
The new CPS series of sirens from CUI (https://www.digikey.com/en/product-highlight/c/cui-devices/cps-series-sirens) is a nice and easy way to add a very loud alarm, and comes in a few different shapes, styles and output effects. They're all about 100 dB, as loud as a jackhammer or motorcycle. Inside, they're buzzer/piezos - but really large ones, that are driven by 12V DC. What I like about these is that you don't need to generate the audio waveform from a microcontroller: they start warbling or beeping the moment power is applied. Why is this good? Well you probably have a nice speaker output system in your design, whether its a DAC, PWM or I2S output, and that's good for nice harmonic tones, verbal alerts or even sound clips - all of those kinds of alarm designs are covered by standards like ISO IEC 60601-1-8. But what happens when you have a power failure or a software interlock failure? You may not be able to depend on your software system. These can be controlled or powered by solid-state technologies that don't have a clock or software, as a backup alarm.
CUI Devices’ CPS series sirens utilize piezo technology with a built-in driving circuit to offer designers a range of variable tones and sounds, including hi-lo, warble, and more. The CPS models feature sound pressure levels (SPLs) up to 120 dB as well as through-hole, panel mount, and wire lead mounting styles. These piezo sirens can carry operating temperatures from -30°C to +85°C, making them well-suited for security systems, medical devices, harsh environments, and industrial applications.
Piezo technology with built-in driving circuit SPLs up to 120 dB Multiple mounting configurations Hi-lo, warble, sweeping, one tone, and six tone offerings Operating temperatures: -30°C to +85°C
There's a few in this series, from one that looks like a little horn, to an enclosed box. If we had to pick one to try out, we'd say the CPS-7560 (a.k.a 102-CPS-7560-110L450-ND) is the cutest one, with a panel mount style that evokes an arcade button. This design looks super easy to mount - you just need a round hole in your panel, and is unobtrusive. You can check out that part here:

This week's EYE ON NPI looks at a new collection of 1552 series enclosures from Hammond Manufacturing. (https://www.digikey.com/en/product-highlight/h/hammond/1552-series-abs-plastic-enclosures)
Pre-fabbed ABS plastic enclosures don't get much attention these days - especially since folks can 3D print a case. But for prototyping or even small (less than 1000 pc) runs, these cases can make your product or project look really good. These 'soap' size cases feel good in the hand, with nice bevels. They come with removable end panels - you can use these for panel-mount switches, knobs or LEDs by drilling with any floor drill or CNC. You can also pick up extra panels if you need extras while you work out the design. Then the front can take a sticker and be machined or hand-cut as well. Note that they cannot be laser cut since they are made of ABS.
These off-the-shelf boxes have really improved in the years since we've used them - for example these come with nifty mounting plates that hold the enclosure, and cable gland pieces that can replace the end-panels to make a fancy user-control-box.
Hammond’s (https://www.digikey.com/en/supplier-centers/h/hammond-manufacturing) 1552 series of handheld ABS plastic enclosures offer elegant, modern style and comfort, while a range of accessories adds capabilities for a host of common applications. Comfort in the hand allows 1552 enclosures to be used for long periods with minimal fatigue in applications, such as machine or electric hoist control. Both end plates are removable for easy machining and are swappable with an integrated TPU cord-grip end panel, which provides input/output and strain relief solutions for cables. The integral cable clamp keeps internally routed cables firmly in place without damage. When device storage is required for applications such as medical instrumentation, a wall-mounted holder is available as an accessory. The 1552 series enclosures fit snugly into the holders, which are also fully compatible with cord-grip end panel kits.
We particularly like the look of the 1552C3BK (https://www.digikey.com/product-detail/en/hammond-manufacturing/1552C3BK/164-1552C3BK-ND/11201091) which is about 4" long, 2" wide and almost 1" deep. For the best experience, you'll want to design the PCB that fits inside so that it's less than 95mm x 45mm and has four mounting holes to match the internal bosses. Hammond has tons of great resources such as 2D and 3D STEP files - and they can customize the enclosure with pad printing and/or cutouts so you have a nice in-between option that is faster and nicer than 3D printing but not as expensive as a custom injection mold.

This week's EYE ON NPI looks at a nifty collection of RF reference designs and eval boards from NXP. (https://www.digikey.com/en/product-highlight/n/nxp-semi/rf-circuit-collection)
RF chips are notoriously hard to lay out, there's a lot of details to worry about: trace widths, via placements, impedance mismatches...so why not use ready-to-go designs? NXP has published a bunch of different RF power amplifier designs, addressing a wide range of expanding markets from smart industrial applications to the 5G revolution
NXP’s RF Circuit Collection is a comprehensive library of RF power amplifier designs, addressing a wide range of fast-growing markets from smart industrial applications to the 5G revolution. This collection can reduce development time with easy online access to proven designs for fast time to market.
These eval boards are beautifully made, and have easy SMA connectors so you can plug-n-play different amplifiers based on your project need. For example, the highlighted board at Digi-Key is the NXP AFIC901N.
The AFIC901N is a 2-stage, high gain amplifier designed to provide a high level of flexibility to the amplifier designer. The device is unmatched even at the interstage, allowing performance to be optimized for any frequency in the 1.8 to 1000 MHz range. The high gain, ruggedness and wideband performance of this device make it ideal for use as a pre-driver and driver in a wide range of industrial, medical and communications applications.
The eval boards are not cheap - these are really high quality and high precision radio devices for medical, science, telecom and industry. The good news is that NXP has a free site set up to download the designs, so you can learn how RF layout is done which will help HAMs and other RF engineers. Check it out here https://www.nxp.com/design/development-boards/rf-circuit-collection:RF-CIRCUIT-COLLECTION
You can pick up an AFIC901N eval board, DK part number AFIC901N-135MHZ-ND over at https://www.digikey.com/product-detail/en/nxp-usa-inc/AFIC901N-135MHZ/AFIC901N-135MHZ-ND/7645443

Make a game clock with multiple timers using your Circuit Playground Express. It's easy to get started with just the Circuit Playground itself, and lots more fun to add a NeoPixel strip and some custom switches and buttons using objects you can find around your house.
This is a great project for learning to code with MakeCode, with lots of customizations to play with. Easily change the timer duration, the colors and sounds for each player, and lots more. Keep your kids engaged and having fun as they learn programming basics.

Full tutorial: https://learn.adafruit.com/sew-a-cotton-face-mask/overview
Pattern Download: https://www.craftpassion.com/wp-content/uploads/2013/08/face-mask-pattern-1.pdf
Stay safe and stylish this spring by making your own cotton face mask. This guide details how to make a double layered face mask using a dish towel and part of a t-shirt. The mask is held on using two hair elastics.
The only other things you'll need are a pair of scissors, a marker, and a needle and thread. If you have a sewing machine, it's easy to use that instead of hand-sewing -- but nobody should be lacking a fancy new mask because they don't have fancy machine, so we've focused this guide on making the mask by hand.
Hand-sewing can be quite relaxing, so pull up your chair by the fire, thread your needle, and make masks for everyone in your family.

Hey folks, thought I'd post an update on what we're working on. We were asked to 3D print protective face shields on Saturday, March 21 2020.
We were inspired by the protective face shield design from Prusa Research. We redesigned the parts using Autodesk Fusion 360 and made them parametric so we can easily adjust thickness, height, etc. https://www.prusaprinters.org/prints/25857-prusa-protective-face-shield-rc2
Check out our Layer by Layer tutorial to see how we designed it. https://youtu.be/BYPWB5-auQE
The RC1 design takes about 2hr 14min. RC2 takes about 2hr 52min and the bottom holder takes 59min. We redesigned the bottom holder so it's longer and able to grab onto the sheet more effectively.
We didn't have any sheets of clear PETG plastic so we used transparency film. We used our CriCut vinyl cutter to cut out the shield using the PDF template from Prusa Research.
We're taking the proper precautions to sanitize the parts before shipping them out.
Check out the Learn Guide for building these protective face shields. https://learn.adafruit.com/open-source-face-shield-designs

Welcome to the latest “EYE on NPI” with the Nordic nRF5340 Bluetooth Microcontroller – available for purchase from Digi-Key. https://www.digikey.com/products/en/rf-if-and-rfid/37?k=nrf5340&newproducts=1
What is EYE on NPI? The acronym NPI stands for New Product Introduction and sometimes you’ll also see NPD (New Product Development). EYE on NPI will showcase, spotlight, and discuss the latest new products and announcements from the entire component industry. EYE on NPI will help engineers go from prototype to market and get important information on pricing and availability. The more you know, the more you can reduce time-to-market, the more you increase the quality of the product(s) and reduce production costs!
Adafruit releases dozens of new products per month. We live, eat, and breathe datasheets and we wanted to share our NPI process with everyone: how we get to market quickly, and what the latest NPIs are out there.
======
This week’s EYE ON NPI takes a peek at the new chips coming from Nordic Semi – makers of some great wireless chipsets and their new major chipset release, the nRF5340!
We’ve been huge fans of the nRF5 series, which has combined a powerful microcontroller and a 2.4GHz BLE radio. We started with the nRF51 which we’ve used in our popular Feather 32u4 Bluefruit LE board, and then moved onto the nRF52 series which is used in the Circuit Playground Bluefruit. So naturally we’re very interested in the latest major version of this family – the nRF5340.
Please note: this is a really new NPI, so new that this part is an engineering sample and is not fully tested. There may be silicon bugs that will be fixed in the final release. Even if it’s not ready for mass manufacture, it’s a great time to start prototyping or developing with it.
According to Nordic:
The nRF5340 is the world’s first wireless SoC with two Arm® Cortex®-M33 processors. The nRF5340 is an all-in-one SoC, including a superset of the most prominent nRF52® Series features. Features like Bluetooth® Direction Finding, high-speed SPI, QSPI, USB, up to 105°C operating temperature, and more, are combined with more performance, memory and integration, while minimizing current consumption.
The application processor is optimized for performance and can be clocked at either 128 or 64 MHz, using voltage-frequency scaling. It has 1 MB Flash, 512 KB RAM, a floating-point unit (FPU), an 8 KB 2-way associative cache and DSP instruction capabilities. The network processor is clocked at 64 MHz and is optimized for low power and efficiency (101 CoreMark/mA). It has 256 KB Flash and 64 KB RAM.
The most interesting thing about this new chip is how powerful the processors are – they’ve upgraded the nRF52840’s Cortex-M4 to two M33’s, and doubled the max clock speed to 128 MHz. The second processor will be useful for products where you have very specific real-time requirements, as the Nordic radio software (SoftDevice) can interrupt user code to handle incoming packets. It’s better if you can dedicate one core to handling all radio requirements, and any secure/encryption/sync/authentication work, so the main thread can run on another processor to handle user interface requirements. This chip is powerful enough to run DOOM
You can pick up nRF5340 chips right now from DigiKey, and don’t forget to also grab an nRF5340 preliminary dev kit as well. We’re a fan of the Nordic DK’s: they’re very complete and easy to use with built in J-Link program/debug, just-the-right-amount of peripherals, and power monitoring support, all for a really great price.

Complete your Wizard or Druid cosplay with a glowing, ever-burning fire staff. This prop is lightweight and sturdy, and made from inexpensive materials. You don't need much in the way of sculpting ability to create something organic and magical, that looks as though it was cut from the Yggdrasil with an enchanted axe and then imbued with fires from the Mines of Moria before serving the White Witch Jadis for a century or two and then falling into your hands at the end of a rollicking adventure.
You'll need some soldering ability, a little creativity, and a willingness to get a bit messy. You can upload our CircuitPython code as-is, or it's easy to change the colors and sound effects to complement your own Wizard or Barbarian character. This would also make a wonderful staff for a monster or Fairy Queen with a few stylistic variations.

“EYE on NPI” with Maxim's Himalaya uSLIC Step-Down Power Module https://www.digikey.com/en/product-highlight/m/maxim-integrated/himalaya-uslic-step-down-power-module
What is EYE on NPI? The acronym NPI stands for New Product Introduction and sometimes you’ll also see NPD (New Product Development). EYE on NPI will showcase, spotlight, and discuss the latest new products and announcements from the entire component industry. EYE on NPI will help engineers go from prototype to market and get important information on pricing and availability. The more you know, the more you can reduce time-to-market, the more you increase the quality of the product(s) and reduce production costs!
Adafruit releases dozens of new products per month. We live, eat, and breathe datasheets and we wanted to share our NPI process with everyone: how we get to market quickly, and what the latest NPIs are out there.
We're always on the lookout for new techniques and parts for power supplies and management - so this week's EYE on NPI takes a look at some MAXIM integrated buck converter chip/mini-modules, which they call the Himalaya uSLIC™ Step-Down Power Module set. These tiny and easy-to-use modules take 4.5-36V DC in and give you 0.9V-12V adjustable output at 1 Amp with no fuss.
"The Himalaya series of voltage regulator ICs and Power Modules enable cooler, smaller and simpler power supply solutions. Easy-to-use, step-down power module that combines a switching power supply controller, dual n-channel MOSFET power switches, fully shielded inductor, and the compensation components in a low-profile, thermally-efficient, system-in-package (SiP)."
Power supplies are the silent workhorses of electronics design - they take the abuse of over/under voltages, short circuits, noisy and unstable inputs and do all that clean up for you so you've got clean regulated power. They're not glamorous, but a good power supply setup will make the rest of your design a breeze. Bad power supplies will give you very confusing results - flaky wireless, bad sensor readings, brownouts, or worse - damaged components!
We've seen some of these 'all in one' integrated buck converters before, they're sometimes even sold as pin-compatible 'LM7805' replacements. In particular we're seeing these pop up on small development, wearables or eval boards - partially because they're so small and also because they're incredibly easy to use. You only need half-a-dozen passives to get the MAXM17632 going, even less for the fixed-output MAXM17630 and MAXM17631.
No inductors, MOSFETs, compensation path - everything's internal. You can get A few external ceramic capacitors and resistors are all you need. It even comes with some nice extras like an under-voltage lockout, adjustable switching frequency (400KHz - 2.2MHz) and a powergood/reset output that can keep your system from booting up during start-up.
These modules are tuned and efficient, especially since every component is tightly integrated, so you will reduce thermal emissions as well. Check out this nifty thermal camera live demo video by Maxim.
We picked these parts because we have encountered projects where the power supply needs to be super small, super efficient, reliable and the additional cost of an external module did not affect the BoM

We are kicking off "EYE on NPI" with the Espressif ESP32-S2 SoC (video). What is EYE on NPI? The acronym NPI stands for New Product Introduction and sometimes you'll also see NPD (New Product Development). EYE on NPI will showcase, spotlight, and discuss the latest new products and announcements from the entire component industry. EYE on NPI will help engineers go from prototype to market and get important information on pricing and availability. The more you know, the more you can reduce time-to-market, the more you increase the quality of the product(s) and reduce production costs.
Adafruit releases dozens of new products per month, we live, eat, and breath data sheets, we wanted to share our NPI process with everyone, how we get to market quickly, and what the latest NPIs are out there.
Espressif ESP32-S2 SoC modules and development boards were announced in 2019 and we're getting closer to having these in hand. Last week Espressif announced the beginning of mass production for the whole series of ESP32-S2 SoCs, modules and development boards, which will make their advantages readily available to the entire IoT market.
ESP32-S2 is a truly secure, highly integrated, low-power, 2.4 GHz Wi-Fi Microcontroller SoC supporting Wi-Fi HT40 and having 43 GPIOs. Based on an Xtensa® single-core 32-bit LX7 processor, it can be clocked at up to 240 MHz.
With state-of-the-art power management and RF performance, IO capabilities and security features, ESP32-S2 is an ideal choice for a wide variety of IoT or connectivity-based applications, including smart home and wearables. With an integrated 240 MHz Xtensa® core, ESP32-S2 is sufficient for building the most demanding connected devices without requiring external MCUs. By leveraging Espressif’s mature and production-ready software development framework (ESP-IDF), ESP32-S2 achieves a balance of performance and cost, thus bringing faster and more secure IoT connectivity solutions to the market.

Discover your inner Snow Queen with this temperature sensing pendant. Invoke the elements of snow, air, and fire using your breath or body heat (or your Ice Queen Superpowers). The pendant will display a snowflake, a spinning leaf, or a lovely purple flame animation depending on the warmth of the air.
Inspired by the elemental spirits in Disney's Frozen II movie, this pendant will be sure to inspire and excite any Queen Elsa fans, and add an element of magic to your cosplay or halloween costume.
This project uses Adafruit's TFT Gizmo, a Circuit Playground Bluefruit, and a 3d printed case. There's no soldering or coding involved -- just a few screws to tighten, and a couple files to upload -- so it's a wonderful beginner project if you're just starting out in the world of electronic cosplay, or if you have a young helper who's getting interested in making stuff.

The PLEN robot from Japan https://plen.jp/wp/plenbit/lled-robot-using-the-micro-b/description is an adorable 8-servo humanoid robot. It’s designed to fit a micro:bit and we can also get it working with the CLUE in CircuitPython. This example is just turning on the eye LEDs and moving the arms around, a great basis to build upon! Code is available here - https://github.com/ladyada/Adafruit_Learning_System_Guides/tree/master/CLUE_plenbit_demo

Arturo sent us some Feather M7's based on the fancy new RT1011 - this chip runs at 500 MHz but is only a couple $. With plenty of QSPI FLASH on board and RAM, it can make for a nice IoT engine. Here I'm using it with our ESP32 AirLift FeatherWing for WiFi connectivity, and a small color TFT. The code is about 80 lines of CircuitPython - available here https://github.com/ladyada/Adafruit_Learning_System_Guides/tree/master/CircuitStonks

In this video we’re taking a look at Adafruit’s Clue dev board. This features the same shape and size like the BBC micro bit so it’ll work with existing add-ons. Adafruit Clue has a 1.3in IPS display so you can make projects with text and graphics. It’s packed with sensors like accelerometer, gyroscope, magnetometer, pressure, temperature and much more. It features the nrf52840 cortex M4 processor with 2mb of internal flash. It also has a microphone, speaker, neopixel and STEMMA connector so you can plug and play even more sensors. With bluetooth you can make wireless projects that can control your BLE devices. For example, you can control your phone using Apple’s Music Service to play, pause and even change the volume.
With adafruit’s circuit python you can make cool projects using adafruit’s libraries and demo code.
The learn guide has all the documentation you need and examples so you can quickly get projects up and running. With circuit python your code and libraries live on the board like a USB drive so you can access your code on any computer. This makes development really fast because you don't have to compile the code so you can see your updates almost instantly. So Get Clue and start learning how to sense the world around you.

We can't wait for spring to arrive, and we're looking forward to caring for some plants! We designed this little add-on for micro:bit or CLUE boards - you just bolt it on with 5 screws to get a buzzer/beeper, motor driver and breakouts for connecting a soil sensor (two alligator clips + nails work just fine), simple, but effective!

The CLUE board has a 9 DoF motion sensor (accel/gyro/mag) that can be used to calculate orientation. It's hard to visualize using just text. Normally folks would use a Processing sketch to display the 3D model but now that webserial is available in the browser, it's much easier to use that! This website uses webserial to get the Euler angles & three.js to display a bunny that moves around. We'll update it to use quaternions next :)

Oooh this is super early, but we love testing out fresh alpha code :) This is maker.makecode.com support for the Circuit Playground Bluefruit (nRF52840) - only a few things work right now: buttons, NeoPixels, speaker and the accelerometer! Definitely doesn't have wireless support yet, and some things are missing. This isn't an official supported platform, so stay tuned for more!

Real names tell you the story of things they belong to in my language, in the Old Entish as you might say. It is a lovely language, but it takes a very long time saying anything in it, because we do not say anything in it, unless it is worth taking a long time to say, and to listen to.” --Treebeard the Ent
JRR Tolkien
Your best projects are certainly worth taking a very long time to build. Luckily, the genius programmers at Adafruit have taken the time to create and build the amazing Monster M4sk -- a plug-and-play TFT display "mask" that makes bringing life to your props and creatures incredibly easy.
Power it with a USB cable or battery and upload custom graphics with drag-and-drop. In just minutes, your project will wake up, blink a few times, and proceed to delight and astonish anyone who encounters it.
This tutorial goes into detail about the Monster M4sk setup process, and gives a lot of info about how I built the tree to house it. It's not a step-by-step tree-build tutorial, but it will definitely give you the tools and a road map of how to create your own tree or monster or movie prop using expanding foam and a few simple hand tools.

Over the weekend we wrote a plotter/scope for the CLUE in Arduino - you can plot any of the built in sensors (light, temperature, pressure, humidity, color, proximity, accel, gyro, mag) all directly on the 240x240 display. we even added auto-scaling! this makes it really easy to test out the sensors and measure the world around us :)

This project uses a Circuit Playground Express to control nine beautiful, crafty fairy bottles hanging from the branches of an indoor tree sculpture. Capacitive touch metal buttons select color modes based on the four seasons: a relaxing rainbow for summer, flickering candlelight for autumn, raindrops and lighting for winter, and a beautiful energetic and colorful animation for spring.

Last week we did a couple guides on calibrating sensors. This week we're taking that calibrated data and putting it through some filters to create orientation data. We're using PJRC's orientation visualizer which is an easy way to see which way the board is oriented - nice and stable.

The Chrome browser supports WebSerial - that means you can get serial port data fast and easy into a webbrowser - easier than WebUSB! So of course Melissa whipped up a great little plotter/monitor that you can use to display incoming data from an Arduino, Circuitpython, whatever microcontroller! Works great, we're still working on features and performance but you can try sending it CSV data here: https://adafruit-webserial-plotter.glitch.me/

Adafruit and Digi-Key have teamed up to present All the Internet of Things - a six-part video series covering everything you could ever want to know about the Internet of Things.
http://www.digikey.com/alltheiot
We are excited to release Episode 6, the final episode of this series, which incorporates all the different subjects we discussed in our previous episodes and shows off an incredible resource: Digi-Key IoT Studio.
Unlike most other IoT platforms, Digi-Key IoT Studio is code-less — all sensor interaction and storage is done automatically by the drag-and-drop IDE. You don't need to install toolchains, code editors or compile any code on your computer! Digi-Key Studio runs in your web browser, handles all aspects of developing an Internet-of-Things project, and even compiles your code remotely.
If you aren't already using it, check out this guide to get started now. https://learn.adafruit.com/digikey-iot-studio-smart-home

We're getting close to adding support for a new STM32F4 board to CircuitPython. This is the KittenBot Meowbit, its microbit-like at the bottom but has a display and d-pad for Microsoft Arcade games. And now it even works with CircuitPython! Stay tuned for when the PR is merged, and try it yourself.

Bright Wearables bags and backpacks contain a colorful circle of light that you control with code, works with micro:bit, and we wanted to make sure it worked with the upcoming board, CLUE.
One cool thing with CLUE is kids could drag and drop any image they want, like a Powerpuff girl to the USB drive that shows up when you use a CLUE. CircuitPython works with Bright Wearables!

Teachable Machine is a new free service for TensorFlow experimentation that takes the pain out of training models. In just a few moments you can get video data for image recognition, train a model and export it for use with TF or TF Lite. Here we use a mod of 'tiny sorter' to send WebUSB signal to a Circuit Playground Express to light up LEDs based on which class was detected.

Have at look at the latest art for CLUE, images above and a vid with CLUE spinning around. Sign up here to get an email when CLUE is shipping! https://www.adafruit.com/clue
What is CLUE? We wanted to build some projects that have a small screen and a lot of sensors. This board has a 1.3″ 240×240 IPS TFT display, two buttons, and a ton of sensors: LSM series 9-DoF motion - LSM6DS33 Accel/Gyro + LIS3MDL magnetometer APDS9960 Proximity, Light, RGB, and Gesture Sensor PDM Microphone sound sensor Humidity, temperature and barometric environmental sensing
There’s a Qwiic / STEMMA QT connector for adding more sensors, like PM2.5 air quality and others that were too big to fit on the board. We’ll be primarily using CircuitPython for programming it, but it will also work in Arduino. And of course, we’d love to see MakeCode on it! After designing it, the board was close enough to micro:bit-shape-size that we moved a few parts to make it fit in micro:bit robots and some projects – the nrf52840 is a big upgrade chip and can do stuff like Tensorflow Lite for Microcontrollers, BLE central and peripheral, and more.

The Adafruit CLUE board comes with a magnetometer & magnetometers need calibration before use. Sometimes a program is used to help calibrate but since there's a screen, we can calibrate on-board using the display. Before calibration, the X/Y/Z data is shown as red, green and blue balls of datapoints that are not centered. Once you see enough data, press A to calibrate. Then the X/Y/Z data will be calibrated-centered!

Scott and Artur have done an amazing job bringing CircuitPython to the NXP iMX RT1062, this chip holds a lot of promise! I threw together a quick IoT project to test I2C and SPI - the OLED is an I2C device, and the AirLift Featherwing provides WiFi over SPI. This demo connects to my AP, then queries the adafruit quote service to get an inspirational quote every 3 seconds. The JSON is parsed, split, and displayed on the OLED by scrolling. Was really fast to put together, only about 20 minutes and 100 lines of code.

Coming soon ... Preview - FEATHER Bluefruit Sense!
Since we've experimented with adding all sorts of sensors to our new CLUE board (see previous newsletters for more info about CLUE) - we thought we'd try adding the same bevy of sensor goodness to a Feather nRF52840. We removed the SWD connector and also the optional 32 Khz crystal. In their place we added a PDM mic, LSM6DS33 accel/gyro + LIS3MDL magnetometer, SHT3x humidity sensor, BMP280 or DPS310 barometric pressure sensor, and APDS-9960 color/light/proximity/gesture sensor. Should a fun little feather board, will pair very nicely with a ADALOGGER featherwing for RTC+SD card datalogging.

Only took us a few minutes to compile our TF Lite micro demo from the Circuit Playground Bluefruit over onto the CLUE board. It uses the same nRF52840 chipset and PDM microphone - worked well out of the box! With all the sensors on CLUE it will make for a good platform to try out various sensor-learning projects!

There are lots of FeatherWings out there, and it would be rad if we could easily add them to our micro:bit projects, right? This little adapter takes a micro:bit form-factor board, like the original or our CLUE and rearranges the pins so you can plug in any FeatherWing. There's even a lipoly battery charger and on/off switch for portability - take Flight with micro:bit + Feather!

Build a motorized camera slider with Adafruit Feather and CircuitPython! Create HyperSmooth motion timelapse video with this build! Learn Guide: https://learn.adafruit.com/circuitpython-motorized-camera-slider/
This project uses the Adafruit Feather platform and CircuitPython to make an easy to control motorized camera slider. The build uses aluminum extrusion to support a linear rail system with 3D printed parts. A camera can be mounted to the platform and slide along the rail. You may use the joystick and buttons to trigger different time settings presented on a mini TFT display.
FeatherWings
The mini TFT FeatherWing is perfect for selecting settings and displaying modes! The MotorWing provides the Feather M4 with stepper motor control and makes it easy to connect. A Tripler FeatherWing keeps everything in place and makes it modular.
Features
The program features four timing presets to select from using the joystick and switch. 5-min, 10-min, 20-min and 60-min. The status of the slider is displayed while it's in motion. Time remaining is also displayed alongside a nifty graphic and icon. When the slide is approaching the end, a STOP graphic is presented.

This weekend, we finished adding Blinka support for the low-cost MCP2221 USB to I2C/ADC/GPIO converter. This demo shows using Mu to plot sensor data with no microcontroller programming - we run Python natively on the PC, reading the sensor data through the USB/I2C converter. We think this could be really powerful when you want to do datalogging or analysis on a powerful computer, as there's no intermediary. We have 200+ CircuitPython libraries, and many are I2C-compatible sensors :)

Want to be like the Predator and have thermal vision? Well, maybe not with the 2 hour dental cleanings. So, instead, DIY thermal vision with this MLX90640 thermal camera with STEMMA QT connector so it plugs right into the BrainCraft HAT. We're displaying the heatmap output right on the 1.54" TFT. We think this could be useful for training ML/AI models that are looking for 'heat signatures'... maybe could differentiate between Xenomorphs, Humans, and adorable kittens!

This weekend we worked up making a Stemma QT (qwiic/Grove compatible) breakout for the MLX90640 32x24 camera. We've got it working nicely in Arduino up to about 8 fps (you need a fast processor like the SAMD51 with lots o RAM). Then we went back to our old AMG88xx thermal cam demo and ported it to our EdgeBadge. This camera could be good for low cost thermal imaging and also machine learning!

We're testing out a new PR in CircuitPython by JEpler. This one adds native MP3 decoding - no playback chip required! Thanks to the patent expiration, we can now distribute MP3 decoding and its a great way to support compressed audio playback. We can even play 2 mp3's at once. More than that isn't possible yet due to RAM constraints. I'm testing an nRF52840 BLE feather with I2S. We'll also try SAMD51 next. SAMD21 won't be able to do it, due to the RAM requirements.

Design beautiful customizable luminary lanterns for your home or garden. Cut them out on a vinyl cutter or laser cutter, and fill them with light using a Circuit Playground Bluefruit Express and Adafruit's NeoPixel rings. Add custom color animations and control the lanterns with Adafruit's BlueFruit app.
We've also added capacitive touch control, so you can change color modes just by touching the lantern. Circuit Playground Express has all this functionality already built-in, so it's easier than ever to create gorgeous controllable lights.
If you're making just one lantern, this project doesn't require any soldering at all! The Circuit Playground's onboard lights will do the work. If you want to make multiple synchronized lanterns, it's easy to solder NeoPixel rings to the Circuit Playground and string together as many lanterns as you'd like.

For best results be on a wired connection and have a headset and mic!
Learn Guide: https://learn.adafruit.com/circuitpython-sprite-animation-pendant-mario-clouds-flying-toasters/
In this project we’re making retro inspired wearables! The pendant features an IPS display with animated graphics. It uses Adafruit’s CircuitPython to create animated sprites that look like flying toasters and scrolling clouds.
We originally did these two as Pro Trinket projects, with a monochrome OLED for the toasters, and a color OLED for the clouds. To keep up with modern times, and the new high visibility IPS displays, we've upgraded both projects here to use CircuitPython instead of Arduino for easier customization. The displays also look a lot better, but the price and construction is about the same!

The EdgeBadge and Circuit Playground Bluefruit have a built in 3-axis accelerometer, so they're ready to try out the TensorFlow lite demos for recognizing gestures. The default tflite file has three gestures it can recognize: WING (W), RING (O) and SLOPE (L). We light up the LEDs as well as show the detected gesture on an attached display Check out the code here to try it yourself! https://github.com/adafruit/Adafruit_TFLite

We like to visualize our ML output, so when we loaded up the new Arduino TensorFlow library, we wanted to try adding a screen. Here we take an X coordinate, pass it through TensorFlow model that has learned what a sine wave is, and get a Y coordinate back. Here we are plotting the X & Y on the display as a red ball. We had to slow it down a bit so it was visible!

Send images via Bluetooth LE to your Circuit Playground Bluefruit with the Adafruit Bluefruit app for iOS and Android. Displayed on the beautiful TFT Gizmo screen! Coming up on the next John Park’s Workshop.
Create a growling, barking Fizzgig puppet with a moving mouth and animated OLED eyes. He's fierce and fancy, with sound effects and animation, and he's surprisingly easy to build. The MonsterM4sk board does all the work.
Installing software is as easy as copy/pasting a few files. Then, plug in a servo, speaker, and hook up a trigger button, and you'll be growling at passers-by and protecting all the Gelflings in no time.
This is a great build to do with kids since most of the work is in building the craft-foam mouth and getting his hair just right.

Make custom "holograms" with Adafruit’s PyPortal. This uses an inexpensive hologram prism and a servo to create a spinning "hologram" (also known as Pepper's ghost). With Adafruit’s PyPortal, you can easily play animated GIFs and project your own artwork. In this video, we’ll show you how to wire up the electronics to make it portable. The components are secured to our 3D printed parts and designed for an easy assembly. We’ve made it portable so you can hold it in the palm of your hand.

Mix NeoPixel colors wirelessly with a Bluetooth LE remote control RGB mixer!
Use a pair of Circuit Playground Express boards to build a remote controlled colored light mixing system! No mobile device or computer necessary. CircuitPython code makes it simple to create a client/peripheral BLE communications system. Read potentiometers on one CPB and send those values as RGB color packets to the second CPB running a strip of NeoPixels.

This dress was created for the Reinvent the Runway 2019 show in Rocklin, CA. It's made of plastic grocery bags and bubble wrap, and powered by Adafruit's Circuit Playground Express. The dress is motion sensitive and puppeted using fishing line connected to bracelets made of plastic soda bottle rings. The necklace is also made of soda bottle rings, and the fascinator hat is a small turtle made of a soda bottle. The theme was Science, and all the entries needed to be made of recycled materials.

HWUF in this project we are upgrading our candy bowl with an animated eye.
This year we’re tricking out our candy bowl with Adafruit’s HalloWing M4.
This animated eye looks pretty realistic and you can use the touch pads to trigger LED animations.
So get ready to win this years Halloween with animated eyes.
The HalloWing M4 has everything you need to add an animated eye to your projects.
It features a new IPS display so it looks great at just about any angle.
It’s also has built in NeoPixels, so you create some really nice lighting effects.
In this project, you can touch the pads to cycle through four different LED animations.
It’s really easy to setup the HalloWing M4 with new software. With Adafruit’s firmware, you can install new programs without having to setup arduino. Just download the UF2 files from the learn guide. Plug in over USB and double press the reset button to load the BOOT drive. Then just drag and drop the UF2 file onto the USB drive. The board will automatically restart with the new software. This makes the process so much easier so you can quickly get your projects up and running. It’s never been easier to add electronics into your projects.
This was a lot of fun to work on and we hope this inspires you to get your projects ready for halloween. Be sure to check out the adafruit discord server so you can chat with the community. We wanna give big shout out to you folks sharing your projects! We invite you to Adafruit’s Show and Tell Live stream so you can be awarded a free vinyl sticker.
Thanks for watching and don’t forget to subscribe for more projects from Adafruit.

Wow, yesterday we got our MicroPython PR merged, and today we've got a PR out to the stm32duino team to add this fine Feather as a supported board. This demo shows how we have I2C support working with a 128x32 OLED and a STEMMA QT MSA301 accelerometer. With the connector right on board, its plug-n-play easy to add sensors!

Learn Guide: https://learn.adafruit.com/cappy-monster-m4sk
In this video we’ll show you how to use Adafruit’s Monster M4sk and attach it to your hat with our 3d printed case.
The Adafruit Monster Mask is an all-in-one board that’s designed for beginners looking to add electronics to their projects.
With the monster mask you can customize the eyes to match the theme of your character.
The board is designed so it can be split apart and joined back together with a cable. So you separate the eyes or bring them closer together which is great for projects like Cappy.
It's really easy to customize the look of the eyes. Just open the text file and change things like the size of the iris or the color of the pupils.
Check out the Learn guide for a quick start and read through all of the different options you can play with. The guide covers everything you need and there’s lots of great projects for inspiration.
You can get the parts to build this project, links are in the description.
Download the files and 3d print the parts. If you need to make any changes, you can modify the source files and remix the design.
We got this really nice Cappy hat from Amazon. It’s got padded polyester so it feels comfortable.
You can separate the eyes using flush diagonal cutters. Just follow the perforated holes. Be sure to do this in a well ventilated area and avoid breathing in any dust.
With the PCBs separated, you can connect them back together with a 9-pin JST SH cable. This gives you about 10cm of distance. For this project we’ll bring them closer together.
Start by installing them into the case. You can use M3 nylon screws to secure them to the built-in standoffs – An electronic screwdriver makes this much easier.
This 500mah lipo battery should give you about 3 hours of battery life. You can use foam tape to stick it behind the PCB.
The eye covers are printed white PLA filament and super glued on top of the case.
Next we’ll need to remove the existing eyes from the hat. Start separating them by pulling apart the edges. We used a ceramic blade to slice through the glue. We were pretty careful not to cut the fabric or any of the threads. You’ll want to take your time if you want to salvage these eyes.
The 3d printed case is large enough to cover up any glue stains or strands of thread.
To attach the case to the hat we used a needle and thread. We designed tabs on the side of the case so you can stitch it to the hat. You can create a running stitch by passing the needle in and out of the fabric. Just be sure to make a knot and tie off the thread to keep it from coming undone.
And there you have it! That's how you make Mario’s Cappy with animated eyes.
If you have any projects you’d like to share, we invite you to come on adafruit’s show and tell live stream. Attendee’s get a free vinyl sticker. Also be sure to join Adafruit’s Discord server and become apart of the community!

Enhance a simple rubber hand puppet with MONSTER M4SK eyes and voice changer!
By snapping the MONSTER M4SK in half (safely!) and joining the halves back together with the 9-pin JST SH cable, you can place extra awesome eyes on a rubber hand puppet, such as the dinosaur shown here. And, the PDM microphone and audio output allow us to run voice changer code for extra puppeteering fun!

========= Tim Clarke Master Toy Designer "King of Gross"
For over 30 years Tim has been Inventing, Designing and Sculpting some of the most unusual toys to ever be marketed in the US and abroad. Once known as the "King of Gross" after co-creating in the 80's Sectaurs (Coleco) and Boglins (Mattel). Tim now launches his new line of horribleness the "TOTIMS"
I love creating my own mythology. The world is filled with modern day mythological creatures you can find them in every nook and cranny of your bedroom closet.
Tim Started his career designing and building puppets for the Muppets. Most notable were the Mystics and the Slaves that he sculpted and designed for the movie the Dark Crystal guided by the incredible drawings of Brian Froud. He also worked on puppets for Sesame Street , Muppet Show and Fraggle Rock for which he created Traveling Matt. After Dark Crystal was launched he garnered his first toy sculpting gig with Hasbro creating the Garthim, Mystics and Lanstrider toys.
He has also created toys for Melissa and Doug toys, EK Success, Hasbro, Mattel, Coleco, Kenner, Ideal Lossirs, to mention just a few.
Tryin' out latest TestFlight of the Bluefruit Connect app - we've added a tool to transfer images from your phone or tablet. I can send an image from my photo roll or even take a lovely selfie to transmit. We did a lot of work to get images transferring at a nice speed. We'll release this soon so people can try it out with the TFT Gizmo + Circuit Playground bluefruit.

Max Holiday has been Integrating CircuitPython into many aspects of his PhD research at Stanford University, we had a great time together chatting, thank you Max!
python #circuitpython #adafruit
Topics included:
KickSat-2 development yielded the PyCubed project and after Max's talk at SmallSat 2019 over 60 universities have reached out wanting to use and/or incorporate PyCubed into the Cubesat development efforts.
All of the radiation testing, data collection, etc ... for the research is collected using CircuitPython
I’m real excited lately with the time-of-flight ranging capability of the Semtech SX1280 radios. So Max built a breakout that fits existing HopeRF footprints and published a working (albeit rough around the edges) CircuitPython library!
Max was in NYC for this Keysight IoT competition. Using the KickSat-2 CircuitPython platform (the small form-factor sprites), Max's team worked with a chemical engineering group at Stanford to develop a completely new means of measuring ammonia concentrations in water. The mesh network: gateways, sensing nodes, etc… are all using CircuitPython. THEY WON!
Max's contributions to the maker community and Stanford curriculum include:
Max developed the SAM32 board as a “catch-all” or swiss-army knife for student projects, it's is now part the curriculum in 5+ courses in the fall.
One example, Eng240, is a MEMS course that’s historically been purely theory-based. However, Prof. Roger Howe and Max have overhauled the class to include labs in the fall. The first of which have students assembling their own SAM32, the second has students designing their own “marco” accelerometer using PCBs. Everything is driven with CircuitPython.
Max is a self described soldering nerd - and was completely dissatisfied with resources online for folks learning to solder. Max made a very polished tutorial with a self-assessment quiz. Then coupled it with a soldering practice + exam board for Stanford students to use.
We'll be posting more later, wanted to get this out there now so it made it in to our Python on Hardware newsletter!

I was hacking in the lab quite late one night soldering pins and debugging the bytes When suddenly a bang exploded with sparks And a figure emerged from the hazy dark
It wore a mask It wore a monster mask
The monster mask Its eyes were LCD glass
It wore a mask It had some chips on the back
The monster mask And a sweet solder mask
Soon I discovered, I had nothing to fear This ghoulish rage wasn’t how it appeared This creature didn’t want to do me in It just wanted new eyes, so I plugged them right in
It wore a mask I was coding so fast
The monster mask I used some pictures of cats
It wore a mask uploading firmware to flash
The monster mask And the results were a smash!
Wah-oooohhhh Those programmable eyes …
Wah-oooohhhh So easily customized …
Wah-oooohhhh And once we got it all right …
Wah-oooohhhh We would party all night
The monster mask!

The FT232H is a handy USB to gpio/i2c/spi breakout board we've stocked for a long time. It is used by lots of folks as a hardware interfacing bridge. For a long time we've had Python support for it but that support has gotten kinda old and neglected as we've spent a lot of our efforts on CircuitPython. Well, now we have CircuitPython Blinka support, so you can control sensors, oleds, buttons, LEDs and more all via FT232H! All thanks to Carter who fearlessly took on this code support - we'll start writing up a guide in the next week or two.
(note, just got the iphone 11 pro and playing with settings so chill about the vid stuff :)

Complete your Cosplay with a gorgeous glowing crystal-topped magical Wizard staff. Use the Circuit Playground Express' onboard sensors to program magic spells into your staff and control the lighting effects with your gestures: shake, spin, tilt, or swing the staff to trigger your custom light animations.
A Wizard staff should be as unique as the Wizard who wields it. The more care and thought you put into the creation of your magic staff, the more it will bring your character to life. We've included sample code in Microsoft MakeCode so you can customize your staff's animations to suit your character.

We're putting our lil miniPiTFT through some tests, this one is running our TensorFlow Lite tutorial for object recognition, and using the 240x165 pixel screen to see inference output. Makes it a little easier to know what the machine is seeing!

As displays have gotten smaller and higher res, we've seen some really cute mini TFTs. this one is only 1.1" but has 240x135 pixels, great for a little display. we wrote a kernel driver for it, and with the STEMMA QT connector on the bottom, its ez to connect sensors like this MSA301. Then run python scripts to print out the motion output. Fun!

monsterm4sk #halloween #trickortreat
Adafruit and Digi-Key have teamed up to present All the Internet of Things - a six-part video series covering everything you could ever want to know about the Internet of Things. This one is all about security. Why is security so important?
The running joke is that the ‘S’ in IoT stands for security...cause its never there. But safety and security is something you will need to think about at all steps of your design process. There’s going to be billions of IoT devices on-line around the world, many of which will be connected to the Internet, and almost all of them will be unmonitored. A 2015 survey by authentication service provider Auth0 found that 85% of IoT developers admitted to being pressured to get a product to market before adequate security could be implemented. And as an engineer, you’re probably used to that pressure to get a product to market, in which case, selling features often get more attention than security. With more and more of these connected devices being rushed to market, they’ve become a lucrative target. The 2016 Mirai botnet attack used unsecured CCTV cameras that were connected to the Internet to launch a crippling denial of service attack. That one wasn’t even using the cameras to spy on people, it was just using the TCP/IP stack of the embedded linux device to send lots of junk traffic.
Having security as a priority for your engineering and marketing team will not just help you sleep well at night. As we’ve seen with the European GDPR regulations, privacy and security are being legislated. Having poor security will now get you fined and banned in the marketplace. It’s nearly impossible to add security after the fact, so if you want to avoid a devastating recall - listen up and take security seriously.
http://www.digikey.com/alltheiot
We’ve been discussing a lot of different aspects of IoT. In our first episode, we looked at Transports, the physical and wireless mechanisms used to transfer data between things.
In Protocols, we saw the communication standards which enable devices at each end of a transport to “speak the same language” and understand what is being communicated.
Our third video, Services, covered many of the applications and services that actually implement the technology we’ve been discussing. But for our fourth video, we wanted to focus in on a robust Internet of Things service for makers and professional engineers alike: our very own Adafruit IO.
In our fourth video, we showed a great way to get a handle on a service we’re extremely proud of, and one that for the vast number of people starting out with IoT, will do everything they need. We’ve built complete libraries with lots of examples and plenty of ready-to-go code. Connected devices can be monitored and controlled using configurable dashboards with dozens of widgets that allow for easy 2-way interaction with your devices -- complete with buttons, gauges, maps, sliders.
And now, IoT Security!
To get an even more in-depth look at the services, concepts, and technologies outlined in this video, and for more for products and resources, check out: http://www.digikey.com/alltheiot

“Ladyada” Fried and pt will host the Hack Chat on Wednesday, September 11, 2019 at noon PDT / 3PM EDT – Hackaday.
Click here to join – hackaday.io https://hackaday.io/messages/room/2369
We’ve gotten to the point where a $35 Raspberry Pi can be a reasonable alternative to a traditional desktop or laptop, and microcontrollers in the Arduino ecosystem are getting powerful enough to handle some remarkably demanding computational jobs. But there’s still one area where microcontrollers seem to be lagging a bit: machine learning. Sure, there are purpose-built edge-computing SBCs, but wouldn’t it be great to be able to run AI models on versatile and ubiquitous MCUs that you can pick up for a couple of bucks?
We’re moving in that direction, and our friends at Adafruit Industries want to stop by the Hack Chat and tell us all about what they’re working on. In addition to Ladyada and PT, we’ll be joined by Meghna Natraj, Daniel Situnayake, and Pete Warden, all from the Google TensorFlow team. If you’ve got any interest in edge computing on small form-factor computers, you won’t want to miss this chat. Join us, ask your questions about TensorFlow Lite and TensorFlow Lite for Microcontrollers, and see what’s possible in machine learning way out on the edge.

This is a wearable case for the Adafruit Monster M4SK. The 3D Printed case snap fits together and lets you add a headband so you can wear it. The case has all of electronics so it’s nice and portable little package. The open frame design shows off the silkscreen so you enjoy the lovely artwork.
You can wear it as a pair of goggles or work it into your costume projects. They can be worn over your eyes, just be careful as you won’t be able to see very well.
The Adafruit monster Mask packs a ton of awesome stuff into one single board. It’s running a cortex M4, it’s got 8 megabytes of flash storage, USB charging and 2x IPS TFT displays. It also has buttons, light sensor, expansion ports and accelerometer. Be sure to check out the product page for the full run down.
For a quick start, definitely check out the learn guide. The board has native USB support, so you can upload code and recharge the battery. It works like a USB drive so you can drag and drop bitmaps to change up the graphics. You can modify the look and customize the eyes by editing a special config file.
There’s lots of great project examples so you can get started right away! There’s also a ton of great support for programming languages like Arduino and Circuit Python.

This week we're building on last week's Machine Learning project where we run the MobileNet v2 1000-object detector on the Raspberry Pi 4 + BrainCraft HAT (video). This time we're running MobileNet V2 SSD Lite, which can do segmented detections. in this case it has only 90 objects it can detect but it can draw a box around the objects found. That's displayed on the 1.5" TFT on the HAT for human verification. This model's not as fast as the non-segment object detector, about 1.5 fps. We might be able to speed that up by running TensorFlow Lite instead of full TF - we'll work on that next!

The idea behind the BrainCraft board (stand-alone, and Pi “hat”) is that you’d be able to “craft brains” for Machine Learning on the EDGE, with Microcontrollers & Microcomputers. On ASK AN ENGINEER, our founder & engineer chatted with Pete Warden, the technical lead of the mobile, embedded TensorFlow Group on Google’s Brain team about what would be ideal for a board like this.
And here’s a first look! We’ve started to design a BrainCraft HAT for Raspberry Pi and other linux computers. It has a 240×240 TFT display for inference output, slot for Camera connector cable for imaging projects, a 5 way joystick and button for UI input, left and right microphones, stereo headphone, stereo speaker out, three RGB dotstar LEDs, two 3 pin STEMMA connectors on PWM pins so they can drive NeoPixels or servos, and grove/stemma/qwiic I2C port. This should let people build a wide range of audio/video AI projects while also allowing easy plug in of sensors and robotics!
Most importantly, there’s an On/Off switch that will disable the audio codec so that when its off there’s no way its listening to you!

This weekend's STEMMA board is this lil 1"x1" GPS board, with UART and I2C support. On the back is the RTC coin battery. The I2C makes it easy to chain an OLED onto the end, and this one is displaying the NMEA sentences. Working great so far!

circuitpython #braille #madewithmu
https://www.orbitresearch.com/product/orbit-reader-20/
Starting to hack around with a Python REPL, CircuitPython serial with Mu with the Orbit Reader 20 from Orbit Research. The goal/idea is, we have a real-time REPL in Python / serial with CircuitPython / terminal on-device ... so I thought we'd be able to output that to a braille reader. This is the start, using Mu and showing what's going on with the PyPortal
Orbit Reader 20 – Braille Display, Book Reader and Note-taker. Includes an SD Card, Charger and a USB cable.
The Orbit Reader 20 is the world’s most affordable Refreshable Braille Display. It is a unique 3-in-1 device and serves as a self-contained book reader, a note-taker and as a braille display by connecting to a computer or smartphone via USB or Bluetooth.
Equipped with a 20-cell 8-dot display, the Orbit Reader 20 is based on revolutionary braille cell technology developed by Orbit Research. The breakthrough technology uses mainstream components and manufacturing processes to enable unique signage-quality refreshable braille at a fraction of the cost of the piezoelectric technology that has been used in braille cells so far.
When used as a standalone reader, it enables the user to read any file from the SD card. These could be BRF and BRL formatted books, text files or files in any format. This allows students, especially in developing countries, to have content loaded on to the SD card by teachers and use the unit without any live connectivity to a computer or the internet. The reader has features for easy navigation, inserting and editing bookmarks, browsing through folders, etc.
As a braille display, the Orbit Reader connects to PCs and Macs, iOS devices and Android devices. It provides Bluetooth and USB connectivity and can connect simultaneously to multiple devices. Using the screen reading capability on the computing device, such as Voiceover, Brailleback or popular PC screen readers the user can control the functions of their computer or smartphone, use their favorite apps, read and send text messages and email and browse the internet.
As a note-taker, the Orbit Reader offers all essential file creation and editing functions. A user can create new files, save them on SD card and edit existing files. The Orbit Reader also includes file management features, allowing the user to rename, delete, copy, and create folders and files.
The device is inherently language independent and prompts and menus can be easily localized for different geographies. While it offers a host of features, the Orbit Reader 20 is extremely easy to use and allows seamless and instantaneous switching between reader, note-taker and braille display modes, as well as selection between connected devices such as a computer or phone.
The Orbit Reader 20 is very compact, measuring a little over an inch in height and about 6 inches by 4 inches and weighing under a pound. It includes a high-quality Perkins style keyboard with 8 keys and a space bar. It also has a cursor pad with 4 arrow keys and a select button, as well as rocker keys on each side of the braille display to control navigation.
On the back of the unit is a recess in which are located an SD Card slot, a USB Micro B socket and a power button.
The unit is powered by a user-replaceable fast-charging lithium battery which is recharged through the USB port. It is fluid and dust resistant and its construction is optimized for durability in extreme environmental conditions.
Unique signage-quality Braille 20 eight-dot refreshable Braille cells Book-reader mode – read your favorite books and files from SD card Note-taker mode – takes notes and edit files Braille-display mode – connects to computers and mobile devices over USB and Bluetooth Use stand-alone or connected to a computer or mobile device Works with all popular screen readers on Windows, Mac OS, iOS, and Android Read and send messages and emails Browse the internet Control your computer or smart phone

machinelearning #tinyml #ai
Circuit Playground Bluefruit features the nRF52840 Cortex M4 process, and has all those sensors you love from the previous Circuit Playgrounds: light, temperature, touch, and...sound! A built in PDM microphone makes this board perfect for trying out Tensorflow Lite for microcontrollers. This demo records audio via the mic, and then gives feedback on YES (green neopixels plus upwards tone), NO (red neopixels plus downwards tone). So far so good, this could be a handy board for learning the basics of machine learning. We committed our experiments to the Adafruit TFLite Micro Speed repo.

Hey folks, this week we’re making accessibility buttons for the Adafruit PyGamer. These buttons are 3d printed with the braille alphabet so folks can touch and feel the buttons.
We made a full set of these button caps to press fit over the PyGamer switches. They’re are printed flat side down with the stem facing up. All buttons in this kit fit on the bed of the 3D printer and only took a half hour.
Adafruit PyGamer https://www.adafruit.com/product/4242
350mAh battery https://www.adafruit.com/product/4237
Mini Oval Speaker https://www.adafruit.com/product/4227
The braille alphabet will be printed on little cover pieces and super glued on top. The alphabet consists of dots in a 2 by 3 configuration. These dots are quite small but we were able to fit them on buttons with a diameter of 9mm. Each cover piece has it’s own set of dots so you can pick and place any letter you like.
To remove the parts from the bed, I like to use a razor blade. Just need to carefully get the edge of the blade underneath the part without scratching the bed.
While picking out the covers, it might be a bit tricky to make out the alphabet so I suggest a cheat sheet. so you’ll need to be cautious of the orientation when placing the covers.
Just a small drop of superglue is all it needs to bond to the caps. Once you get them on you can test out the button presses and get a feel for the dots. I think it’s interesting how your well fingertips can sense such fine details like these little dots.

Get noticed and stand out at the convention with this DIY light-up badge lanyard. Control the color and brightness with your phone over Bluetooth (BLE) with the Adafruit BlueFruit app. This is a great conversation starter on its own. Pair it with a PyBadge for extra geek points, or make a lanyard for everyone on your team and control ALL the colors. Make it red when you're running late, green when you're ready to network, and indigo when it's time to relax with a cold drink.
This is an easy-to-assemble project that requires a little light soldering and some drag-and-drop code. Most of the work is already done for you!
This is the easiest time I've ever had setting up a Bluetooth-to-microcontroller connection. Get the software installed and .. it just works. Hooray!

Make a light up Master Sword from the Legend of Zelda! This build has motion activated sound effects and LED animations!
The Adafruit Feather and Prop-Maker FeatherWing has you need to add lights and sounds to your projects. NeoPixel LEDs are fitted inside the blade.
This uses the built-in accelerometer and audio amp. When you swing it around, it’ll make different sound effects. On heavy hits it makes flashes and fade the colors of the LEDs.
It has pulsing animation and an idle sound effect that loops in the background. You can make this fit your project by customizing the colors or adding different sound effects. You can recharge the battery or even add new sounds with the USB port. The sword mounts on a computer, just like a USB Drive!

Following up on our earlier mass-storage support announcement for TinyUSB, we just added WebUSB support!
You can now send and receive data over Chrome (or other WebUSB) browsers with Javascript or whatever else is your favorite web programming language.
This can make for really interesting interactions where people don't need any drivers or software to send/receive commands, or perhaps to expose some sort of REPL.
The example code is here: https://github.com/hathach/tinyusb/blob/master/examples/device/webusb_serial/src/main.c
and here's what the webpage code looks like: https://github.com/adafruit/Adafruit_TinyUSB_Arduino/tree/master/docs/examples/webusb-serial
We'll be adding this to our Arduino library shortly, and will follow up when we have the library committed and updated
tinyUSB currently supports SAMD21, SAMD51, nRF52840, various LPCs, and STM32F4 - more chips will be supported soon!
tinyusb is an open-source (BSD-licensed) USB Host/Device/OTG stack for embedded micro-controllers, especially ARM MCUs. It is designed to be user-friendly in term of configuration and out-of-the-box running experience.
usb #tinyusb #webusb
In addition to running without an RTOS, tinyusb is an OS-awared stack that can run across RTOS vendors. For the purpose of eliminating bugs as soon as possible, the stack is developed using Test-Driven Development (TDD) approach. More documents and API reference can be found at http://docs.tinyusb.org

The idea behind the upcoming BRAINCRAFT board (stand-alone, and Pi "hat") is that you'd be able to "craft brains" for Machine Learning on the EDGE, with Microcontrollers. On ASK AN ENGINEER, our founder & engineer chatted with Pete Warden, the technical lead of the mobile, embedded TensorFlow Group on Google’s Brain team about what would be ideal for a board like this. What did we come up with? Here is a start!
machinelearning #tensorflow #ai
https://blog.adafruit.com/2019/07/28/designing-the-machine-learning-board-on-the-edge-braincraft-tensorflow-adafruit-machinelearning-tinyml/
Inputs: Loads of sensors! Can be connected via stemmaQT. Image sensors, like a camera, Panasonic Grid-EYE. Heat-Sensitive camera, person detector. Microphone, voice detection for powering off. Accelerometer, gestures, vibration sensing, predictive maintenance.
Outputs: Screen for debugging Speaker for audio feedback as to what is going on. Relay control to turn things on/off, etc. and/or actuator.
Connectivity: NB / Narrowband IoT. Wireless flexibility. Works with adafruit.io, of course!
Power: Battery powered / low-power. Solar add-ons, energy harvesting, OK with lots of power sources that are not reliable. On/off switch!

STEMMA is not an original idea, we’re working within an ecosystem of many other plug and play systems. We started STEMMA in 2014, and intended to be compatible with Grove only (cause that’s all that existed at the time) but then when Qwiic came around in 2017, added a smaller connector so we could work with those parts too!
stemma #grove #qwiic
STEMMA attempts to be as cross-compatible as possible with both Grove and Gravity (compatible connectors & 3-5V power/logic). STEMMA QT is cross-compatible with Qwiic - STEMMA QT connector/cable is same as Qwiic. You can use STEMMA QT devices with Qwiic devices/controllers.
Adafruit STEMMA & STEMMA QT: Plug & play connectivity – learn.adafruit.com If you’re lookin for the differences between each and what works (and what does not), skip to the comparison page and if we missed anything, post in the comments!

Last year around this time we designed the Hallowing M0. This year we've got the Hallowing M4, which has an upgraded chip, now a Cortex M4 @ 120MHz with lots more memory to run CircuitPython. The display is also upgraded, 240x240 IPS, and we've added 4 side-light neopixels. Other than that, its pretty much the same design. Spooky & coming soon..

We saw these ultra-low cost (20 cents!) 3-axis accelerometers on LCSC a few month ago and have been experimenting with them. They've got +-2/4/8/16g range, and 14bit resolution according to the datasheet. There's also tap & freefall detection which makes them a good alternative to accelerometers that are 2 or 3x the price. We have written an Arduino library to start, so far so good!
On the PCB we're also experimenting with adding JST-SH connects, like Sparkfun qwiic boards. These have a regulator and level shifting so they're a little different but are compatible.

This is a sound board using Adafruit’s NeoTrellis. This lets you trigger audio files so you can play it like a musical instrument. Each button can have different sounds so you can build your own sample kit. All of the electronics are housed in our 3D printed enclosure. The top and bottom covers snap fit so it’s easy to put together. It’s designed to be portable, compact device and it’s open source.
In previous build we used several boards to make a similar project. For this one we can use Adafruit’s Feather and the Prop Maker Feather Wing.
Check out the learn guide for documentation. You can follow along step by step to wire the electronics and build the assembly.
Code on github https://github.com/adafruit/Adafruit_Learning_System_Guides/tree/master/NeoTrellis_Soundbox
CAD files https://www.thingiverse.com/thing:3750704
The software is written in Adafruit’s Circuit Python so it easy to program the hardware. We setup the REPL to print the file names and neopixel colors. This way we can verify the button mapping or catch any errors. The Feather shows up as a USB drive so you can edit the code directly on the device. All of the files live on the drive so it’s easy to change code on any computer.
You Can Shake the device to shuffle the audio. Pressing the button on the side will reset the arrangement. We think it’s a fun demo of what you can with the accelerometer.

We've taken our JSON-configurable TensorFlow machine learning project and added a little more. First up, we've trained a new model for the words 'cat' and 'dog'. Next we've updated the Arduino code to display a different bitmap depending on what word was detected. Let's try out the cat/dog speech detector!

We're working on making it easy to test and configure your edge machine learning devices with TinyUSB and our PyGamer board. The Pygamer shows up as a disk drive thanks to TinyUSB, and you can drag over tflite files right from TensorFlow's training output, and configure the category names in a JSON file. Now we can quickly try new models without recompiling!

Guide: https://learn.adafruit.com/3d-printing-on-diffraction-grating-sheets - You can get shiny Iridescent effects on 3D printed parts!
Double Axis Diffraction Sheets (13,500 lines/inch) https://www.amazon.com/gp/product/B007FZXNL6
When printing, the texture of the diffraction grating is captured in the first layer.
In direct light, reflections look iridescent with rainbow-like patterns!
This technique was inspired by David Shorey (@shoreydesigns). Follow David on twitter and Instagram to see more work and inspirational experiments.

Tiny Machine Learning on the Edge with TensorFlow Lite Running on SAMD51, we have trained a new model that listens for "up" or "down".
You’ve heard of machine learning (ML), but what is it? And do you have to buy specialty hardware to experiment? Nope! If you have some Adafruit hardware, you can build some Tiny ML projects today!
We’ve wrappered the TensorFlow Lite micro speech demo to Arduino so you can do basic speech recognition on our SAMD51 boards.
In this demo we’ll hook up a microphone to our PyGamer to detect “up” or “down” speech and display some mini videos to play if your voice was detected by TensorFlow Lite, move a bubble wand up or down, controlling a servo, and DC motor, all on a Cortex M4 processor, all battery powered! Code is here – GitHub.
https://github.com/adafruit/Adafruit_TFLite_Micro_Speech/tree/updownmodel
We used docker for this, we can easily train more models on our local system, and we've uploaded them here on docker hub! https://hub.docker.com/search/?q=ladyada&type=image

We have a Hackday Hackchat coming up soon, and this is one of the examples we'll be showing off live!
