DS2484 I2C to 1-Wire converter

In theory, there's a lot of 1-Wire devices out there, but in reality almost everyone uses 1-Wire for DS18b20 temperature sensors. the long wire lengths and ease of 'chaining' by sharing a single bus wire makes it perfectly fine for this purpose. you can bitbang 1Wire on most microcontrollers, and some SBCs like Raspberry Pi have kernel module support.

Desk of Ladyada - Load Cells & HID Keyboards https://youtu.be/HoPInrsFSDI

Waiting for prototype PCBs, we started new projects. We're designing an HX711 breakout board with SPI for multiple sensors and updating the NAU7802. Also exploring CH9328 for HID keyboards via UART. Looking for compact 1.27mm pitch SMT DIP switches on DigiKey for a new design.

Preview - Stemma plug-n-play adapter for DS18B20's

one of the perks of working at adafruit is you get to request hardware - and you'll probably get fast turnaround! one of our adafruit.io dev's requested "an easy way to chain DS18B20 sensors for testing with adafruit.io's wippersnapper service" (https://learn.adafruit.com/using-ds18b20-temperature-sensor-with-wippersnapper) at 11:54am and after a few back-and-forth's we spun up this prototype idea.

CH552 QT Py Tester is Ready to Rock

We designed this CH552-based QT Py to play around with this '40 cent' USB-capable chip, and it's been super fun! now the hardware is complete and assembled, its time to test it so it can go into the shop. we wrote a test sketch in Arduino (https://github.com/DeqingSun/ch55xduino) board support package to verify the GPIO are working right on the pogo bed.

TRRS Trinkey makes AT projects EZ

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.

Keep your Pico toes Toasty with a DVI Sock

the Raspberry Pi RP2040 has a fun trick up it's sleeve, er, pants! it can bitbang DVI video output from a series of pins using PIO as long as its overclocked enough and you have the PIO peripherals available. we already designed a DVI PiCowbell (https://www.adafruit.com/product/5745), but we rather like the DVI sock design originating from wren6991 (https://github.com/Wren6991/Pico-DVI-Sock)

Coming soon - Pixel Trinkey!

We were taking a look at the new Windows 11 HID Dynamic Lighting protocol (https://learn.microsoft.com/en-us/windows-hardware/design/component-guidelines/dynamic-lighting-devices) and i thought this would be a good excuse to design a small NeoPixel or DotStar driver board. like many of our other Trinkeys (https://www.adafruit.com/search?q=Trinkey) it is running a SAM21E18, which is a small chip, but the 32KB of SRAM can drive nearly 10,000 pixels! we put a 5V level shifter on a SPI peripheral so they could be used as data/clock or,

Coming soon - More PiCowbell underplates, this time a Tripler!

What? Adafruit Proto Doubler PiCowbell (https://www.adafruit.com/product/5906) is evolving! Congratulations...your Doubler has evolved into a Tripler! We've added yet another Pico footprint to our doubler, now its chonkier than ever and can handle big projects that need 2 'bells in addition to the Pico or Pico W (https://www.adafruit.com/search?q=pi+pico).

Coming soon - CH552 QT Py is a tiny 8051 board

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!

ESP32-C6 Feather is here, time to bring it up 🚀🛠️💡

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!

Coming soon - USB Plug with THM mounting tabs

We've had some requests to get our Trinkeys soldered up with USB C plugs instead of USB A and like, that turns out to not be trivial! we have to find a USB C plug with through hold tabs so they're nice and strong, and ideally one that isn't "Straddle Mount" where you have to manually place it on the two edges of a PCB.
