This is a spectrometer on a chip, and it's getting the Adafruit breakout treatment. The AS7343 is the successor to our AS7341, bumped from 10 channels to 14, with 12 spanning visible light into near-infrared (380nm to 1000nm), plus clear and flicker detection. Same footprint and pinout as the '41, so your existing wiring and enclosures carry over unchanged. Ladyada finished the library and testing, then pointed OpenClaw at an ESP32-S2 TFT hooked up to the sensor. Claude generated a real-time color bar visualization that's one of the nicer sensor demos we've done… hold it over a green light and watch the yellow-green channels spike, wave it past a reddish-orange source and the spectral output shifts to match. If you want to see what multi-spectral color sensing can do, check out the Color Sensing Music Player guide – we use DUPLO bricks that play songs based on color. The AS7343 would make it even better!

This week at the Desk of Ladyada, we're back to hardware... with a baby in a bouncer and an LLM on the clock. The VCNL4010 proximity sensor has been discontinued, so we need to move to the VCNL4030. That means a new EagleCAD library file, and we're testing whether Claude Code (Opus, high effort) can generate one straight from the datasheet. Historically we've had to create a footprint for each device we use - and one of our gripes is how annoying it is to convert when manufacturers spec edge-to-edge pad dimensions instead of center-to-center pitch, which is what every CAD tool actually uses. In our experiment, Claude Code handled the math, got the pad sizes (0.65 x 0.75mm) and pitch (1.05mm) correct on the footprint, arranged logical pin grouping on the schematic and matched pin-to-pad correctly.. It even matched our drawing style by learning from existing Adafruit library files in the repo. The whole run took about 4 minutes and 45 seconds.Nota bene: it's not perfect! Our first pass had schem label overlaps and an unnecessary exposed center pad (Gemini Deep Think was actually smarter about skipping that pad). We also tried having Claude Code design a full QT Py terminal BFF board... it worked-ish but needed enough back-and-forth that doing it by hand would've been faster. Footprint generation is ready for integration into our workflow - maybe we'll kick it off while we review the datasheet - but, full board layout isn't quite there yet. Other things on the desk: we're setting up OpenClaw to subscribe to every chip manufacturer newsletter and generate daily reports on new components worth stocking. New protos include the TMF8806 time-of-flight sensor from AMS (up to 10 meters, and possibly simpler drivers than ST's VL53 series) and a PMW3901 optical flow sensor often used in drone navigation.

This week at the Desk of Ladyada, we're comin' back from maternity leave and getting spun up with a bunch of projects. First, a fun mailbag item: the XTEInk ‘pocket' reader running crosspoint open firmware on an ESP32-C3. Since it's running an Espressif chip, we could also install CircuitPython or WipperSnapper on it…a great side-effect of more off-the-shelf goods coming with ESP32 chips! See also our Yoto-hacking guide on learn. Next, we've been really enjoying running OpenClaw on a Pi 5 and connecting it up to Adafruit hardware to do ‘full circle' test-driven development. We have Anthropic Opus do the datasheet parsing and design document, then ‘farm' out the coding work to OpenAI Codex. After the driver is written, we also have it design tests to verify hardware functionality, using other GPIO pins, NeoPixels, servos, etc., to exercise the chip capability. It's able to run tests and then fix bugs all on its own, then text me when it needs help or to alert that it's done. It's very slick and fun! Finally, using that same system of coding, we had it ‘one-shot' a miniature oscilloscope demo for the unreleased Stemma Friend from way back (well, it took a few back-and-forths to get it just how we like). Could we have coded it by hand? Probably! But we were able to guide the development and get the look and performance we wanted in about 30 minutes of prompting while also laying in bed and chillin' with a newborn.

Ladyada: "I've only had OpenClaw installed on this Raspberry Pi 5 for a couple of days, but boy, have we burned through a lot of tokens and learned a lot. Including what I think is a really fun improvement in my development process: “Agentic test-driven firmware development.” I've used LLMs for writing code as a sort of pair-programming setup, where I dictate exactly what I want done. But this is the first time that I'm giving full access to the hardware to the LLMs and letting Claude Opus 4.5 as a manager to control Codex subagents. Not only does it parse the datasheet for the register map and functionality, Claude also comes up with a full development and test plan, writes the library, tests it on existing hardware, and then also works up a test suite that covers all of the hardware registers to make sure that the library is exercising the entire chip capability. For example, here I give it an APDS-9999 color sensor and a Neopixel ring and tell it, “hey use the Neopixel ring to verify that we're really reading red, green, and blue data properly from the sensor,” and it will do the whole thing completely autonomously… no humans involved! I still review the final code and ensure the tests genuinely validate the functionality, not just take shortcuts. There is a phenomenon known as "reward hacking" (also called "specification gaming"). The model may optimize for passing tests as a metric, rather than ensuring the code truly works as intended. So far, the results have been excellent... no surprise, since these LLMs are trained on Adafruit open-source GitHub repositories!"

We revisit the PCM5122 DAC, test hot-bar breakouts on a big Quad-Color EPD, check new prototypes, and explore linear image sensors

This week we designed some prototypes: CAN FD version of our FeatherWing and BFF. We also designed a board for the AP33772S (https://www.youtube.com/watch?v=ngQT0Et32wM) which we covered on EYE ON NPI - this is a chip that can do extended range USB Type C Power Delivery (https://www.usb.org/usb-charger-pd) and it seems, Programmable Power Supply mode (https://hackaday.com/2025/03/24/pps-is-the-hottest-usb-c-feature-you-didnt-know-about/). Might also do one for the AP33771C (https://www.digikey.com/short/022nd0fp) too with li'l switches like our HUSB238 (https://www.adafruit.com/product/5991). We also wrapped up the STHS34PF80 driver (https://github.com/adafruit/Adafruit_STHS34PF80) and we'll have a breakout for that shortly once we get chips on order. And on The Great Search: CAN-FD update to MCP2515

This week we got Claude working natively on Windows (yay!) which speeds up development since we're not hitting the filesystem through multiple layers. That meant we also worked on a bunch of little breakouts: the BMP585 protos came in and those worked fine. Plus we knocked out the VEML6046 RGB+IR sensor library (https://github.com/adafruit/Adafruit_VEML6046) and started work on a few others. It turns out the bq25628e (https://github.com/adafruit/Adafruit_bq25628e) was not what we wanted in a charger, because ILimit doesn't affect the charge rate, which is like 40mA by default - boo! We'll find another alternative and also try to get back to that bq25798 (https://github.com/adafruit/Adafruit_bq25798) solar charger shortly. We also worked on the e-Ink bonnet, which worked great as rev A and only needed some pinout swaps - thanks to BlitzCity for updating the CircuitPython-api EPD library (https://github.com/adafruit/Adafruit_CircuitPython_EPD) to add support for the bigger 7.5" & friends which we verified on Raspberry Pi and also the Particle Tachyon - speaking of which we are getting Blinka support into main for that board! (https://github.com/adafruit/Adafruit_Blinka/pull/1001) And on The Great Search - 24-bit I2C ADC Chip for RTD sensors #circuitpython #sensorhacks #thegreatsearch

Fresh drivers for Bosch BMP5xx sensors & LiPoly chargers, plus Particle Tachyon fun with web-console shell + Blinka support! Also, heat sink tips for TO-220s. This week at our desk we cranked through a whole mess of drivers. Starting with the BMP580/BMP581/BMP585 series, which had a proper Bosch driver library (https://github.com/boschsensortec/BMP5_SensorAPI) so we wrappered it with Claude (https://github.com/adafruit/Adafruit_BMP5xx) to make a nice Adafruit-y library with I2C/SPI and IRQ support. We plan to stock all three variants of the chip since the driver is the same for all. Then we cranked through the bq25628e (https://www.digikey.com/en/products/detail/texas-instruments/BQ25628ERYKR/21298592) which is a nice buck-mode LiPoly charger with I2C monitoring and up to 2A rate - the I2C driver (https://github.com/adafruit/Adafruit_bq25628e) was kinda long but it's nice to have monitoring built in so no separate lipoly gas gauge is needed. we're using this as practice while we try to get through the bigger/more complex bq25798 (https://www.digikey.com/en/products/detail/texas-instruments/BQ25798RQMR/15666783) driver (https://github.com/adafruit/Adafruit_bq25798). We also got more time to play with our Tachyon: one thing that is really impressive is the web-console shell access! It solves a common issue with Pi's where getting initial access can be frustrating. Using the PiStemma (https://www.adafruit.com/product/6365) and the Crickit instructions (https://developer.particle.io/tachyon/accessories/adafruit-crickit-hat) we are able to get Blinka + CircuitPython libraries going. We'll get those mainlined next week! And on The Great Search: TO-220 Heat Sink: https://youtu.be/uyvxSyJLR00

We've received several requests to update our low/full-speed USB isolator breakout, which used the ADUM4160. Low speed is for peripherals like mice and keyboards, where bandwidth demands are minimal. Full speed suits microcontrollers, audio interfaces, and simple USB accessories. High speed is needed for flash drives, video devices, data acquisition units, and external disks. Unsurprisingly, there's demand for high-speed isolation. We're now exploring USB isolation ICs that support high-speed performance. Stay tuned!

Explore new E-Ink displays and start an exciting SynthIO project this week! Plus, solving LED power issues and hunted for stylish linear pots for our next synth.

Ladyada's diving into solar charging tech with the bq25798 MPPT charger ☀️, exploring IR sensors, drone-friendly compasses, and prepping for another big release ... but take it easy, take it slow ...baby steps

(Re-broadcast, LIVE was not working for all social media on Sunday night, so here ya go! This week at our desk, we spent a lot of our focused engineering time working on e-paper display drivers. These displays are a lot more annoying than TFTs, which have settled on standardized MIPI command sets. Also, they have custom "waveforms" used to configure the refresh technique. By default, we use the built-in waveforms from OTP memory, but it's possible to load new waveforms, letting us do funky stuff like coax 4-grayscale out of a "monochrome" display. We also designed a simple moisture sensor PCB for an ultra-low-cost kit to be used by students—sometimes it's okay to under-design for cost reasons!

Back from the flu & back in action! Check out the latest hardware updates: Fruit Jam Rev C is final, Sparkle Mic fix is in, and new stepper driver tests coming soon. Plus, PiTFT & PoE upgrades underway!

This week at the desk, we worked on getting more small hardware boards done. We revised our 1.5" transparent OLED breakout (oops, pins were swapped), designed breakouts for sensors like the AS5600 (https://www.digikey.com/en/products/detail/ams-osram-usa-inc/AS5600-ASOM/8250257) and STHS34PF80 (https://www.digikey.com/en/products/detail/stmicroelectronics/STHS34PF80/13187390), and updated the NAU7802 (https://www.digikey.com/en/products/detail/nuvoton-technology-corporation-of-america/NAU7802SGI/4929384) to have both ADC ports available. We're also working on another stepper motor driver, since the TMC2209 breakout (https://www.adafruit.com/product/6121) was a big hit. We wrapped and sent out the Triple-output Active Shifting RGB Matrix Bonnet (https://blog.adafruit.com/2025/02/28/triple-matrix-bonnet-makes-big-bright-displays/). Then we finally had a little time to get back into bigger projects, like Fruit Jam, which we re-picked-up! This week we focused on implementing the ESP32-C6 Wi-Fi co-processor, which needed a bit of rework, but now we've got rev C prototype PCBs on the way. ----------------------------------------- Visit the Adafruit shop online - http://www.adafruit.com LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

This week at the Desk of Ladyada, we're getting back into the swing of releasing one or two new products a week after dealing with some tariff-related chaos. Last week we launched the Sparkle Motion Stick and the SEN6x Adapter. Next week, look out for the OPT4048. For the OPT4048, we wanted to easily plot the CIE x & y to a color graph—which used to mean writing a lot of JavaScript (something I haven't done in 15 years). Thankfully, Claude helped generate code, and now it's up and running! Check it out. This week, we also designed breakouts for: ACS37800 30A Monitor, VEML6046, and a Stemma QT adapter for Raspberry Pi bq25798 Solar MPPT Charger. And for this week's The Great Search – 30 Amp Barrier Terminal Blocks

We're back to designing more prototypes to get the product pump primed! Having lots of boards to work with means we can reliably get one or two shipping each week. To that end, here are some upcoming chips we've made breakouts for: SLB9670VQ20FW785 (TPM chip): https://www.digikey.com/en/products/detail/infineon-technologies/SLB9670VQ20FW785XTMA1/11697680 INA237 (Power monitoring): https://www.digikey.com/en/products/detail/texas-instruments/INA237AIDGSR/14004323 INA238 (High-speed current/voltage sensor): https://www.digikey.com/en/products/detail/texas-instruments/INA238AQDGSRQ1/14641449 STSPIN220 (Stepper motor driver): https://www.digikey.com/en/products/detail/stmicroelectronics/STSPIN220/6137574 LM73100 (Hot-swap controller): https://www.digikey.com/short/hfnzpwjq SC16IS74x (UART to I²C/SPI bridge): https://www.digikey.com/en/products/detail/nxp-usa-inc/SC16IS740IPW-128/1301043 We also tested out Codex as an alternative to Claude for code generation. One benefit is the option to select specific models. We tried o3 (which struggled) and o4-mini (which did okay), but Claude still leads for now. Protos are pumping! We're designing breakouts for new chips + testing Codex vs Claude. Also: help us find a WM8960 replacement and maybe... should bring back the DIGG button kit?

TARIFF TALK! WITH LADYADA

New RP2350 chips are here, and we're building fresh "Bones" boards—starting with the Adalogger RP2350. We also fixed Sparkle Motion's power issue and designed a Stick version. Plus, we're exploring tiny 1.1V regulators to optimize future boards.

This week was slow for hardware development—we were getting over being under the weather. But we did poke a little at a PCM5122 breakout board (https://www.digikey.com/short/fnf9t0b1). This chip can do software or hardware control of I2S signals and is preferred by folks who want something a little nicer than the PCM5102 (https://www.adafruit.com/product/6250). We also wrapped up our design for the 8x solenoid driver board—the biggest update is adding indicator LEDs. Lastly, we got our prototypes for the "USB CC Fixer" adapter, which we mostly made so we could charge a really annoying baby monitor, but probably other folks will want to buy it, too. ----------------------------------------- Visit the Adafruit shop online - http://www.adafruit.com LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

Testing a PCM5122 I2S DAC, adding LEDs to the 8x solenoid driver, and prototyping a "USB CC Fixer" to charge a tricky baby monitor. Also we're on the hunt for a stereo I2S amp with 5W+ output.

Testing Claude Code, to automate Arduino coding/debugging for Metro & OPT 4048! On the most recent Desk of Ladyada, we shared our experiments with Claude Code, a new large language model (LLM) tool, to streamline hardware development - WAIT WHAT? That's right!. streamline hardware development! We are using it to automate parts of the coding and debugging process for an Arduino-compatible Metro Mini board with an OPT 4048 color sensor. Using Claude Code's shell access, we can compile, upload, and test code in a semi-automated workflow, allowing the LLM to suggest fixes for errors along the way. The process involves using Windows Subsystem for Linux (WSL) to bridge hardware interaction gaps, as Claude Code doesn't run natively on Windows yet. While the AI isn't perfect for high-level driver development, it's proving VERY useful for tedious debugging and super-fast iterative improvements, bringing hardware automation closer to ...reality. #claude #ai #arduino

This week, we were all over the place with a bunch of different designs and experiments. After last week's analysis of the TLV320DAC3100, we made some updates to the design and re-booked prototype PCBs. We also designed a triple-matrix bonnet: with our latest work on getting HUB75 RGB matrices working on the Raspberry Pi 5, we can now do matrix control on the latest Pi 5 chip. But we're limited by the RP1 chip, so to get big displays going, we'll need multiple strands—these don't use significantly more bandwidth because half of the pins are shared. Finally, we ended the week by getting another older prototype working: the SAM-M8Q is an entry-level all-in-one GPS from u-blox. It comes with both UART and I2C interfaces, plus a built-in antenna, so it's ready to go out of the box. The NMEA interface is trivial, but we also wanted to try out the UBX interface, and thankfully, Claude 3.7 was able to vibe-code it for us in a jiffy.

Heeeey, we're just having a super chill vibe here at the desk of Ladyada—writing a driver for the uBlox M8Q https://blog.adafruit.com/2024/09/10/a-mini-gps-from-ublox-with-i2c-and-uart/ which has both I2C and UART interfaces. As expected, it can do everyday NMEA output, but it can also do UBX, a "compressed" protocol for advanced data reads and writes over I2C/UART—or even SPI on some other chips. However, the UBX protocol is a hugely complex driver to implement, with dozens of commands and hundreds of flags. But why stress when you can viiiibe? We're using this beast of a spec as an excuse to try out the new Claude 3.7, which is doing great at chomping through the UBX documentation roughage and giving us some nice code on the other side. Within an hour, we're able to connect and switch to UBX mode by sending a well-formed message and receiving an ACK. What we like about coding with a good LLM is that it does the work we sometimes get lazy over, like handling various error conditions, timeouts, and verbose error messages.
