Build a motorized motion sensor bat

This breakout board will solve all your multi-rail power-monitoring problems. Instead of struggling with up to 6 multimeters, you can just use the handy INA3221 chip on this breakout to both measure both the high side voltage and DC current draw of up to three power supplies over I2C with +/-1% precision.

Love daily calendars but cringe at the 365 pages of paper waste? This project lets you have a smol electronic version. You'll use a CH32V203 QT Py with its EYESPI BFF to display the date and time on an eInk display. The time is kept with a DS3231 STEMMA real-time clock breakout. Even though the CH32V203 QT Py is for more advanced users, it still plays well with the BFF breakout buddies.

In this project, you'll use a Feather RP2040 USB Host to listen for a specific button combination from your attached gamepad to trigger "turbo mode" aka rapidly sending A button presses. Otherwise, the Feather acts as a passthrough for your controller, sending all of your gamepad inputs as pressed.

The Zelda Echoes Of Wisdom Tri Rod features motion activated LED animations and sound effects powered by CircuitPython and the Prop-Maker Feather RP2040.

If you want to try out HSTX to drive an HDMI monitor or display, this dongle is what you need to take HSTX out and give you a connector with proper level shifting and signal conditioning. Simply connect a 22 pin FPC cable between the Feather RP2350 and Adafruit RP2350 22-pin FPC HSTX to DVI Adapter for HDMI Displays then load DVI output code. In CircuitPython, we have support for 320x240 pixels at 16-bit color, which gets pixel doubled to 640x480. Or, if you're willing to cut some colorspace to save RAM, you can get true 640x480 resolution at 4 / 8 bit color, or 1 / 2 bit grayscale.

Have you ever looked at your various Apple HomeKit devices and thought "if only I could monitor and control my devices in Adafruit IO"? Now you can with the help of the itsaSNAP app. You can use Apple Shortcuts with itsaSNAP to integrate your Apple HomeKit devices with Adafruit IO. You can go even further and use CircuitPython to display and control your devices with your Adafruit IO feeds.

Turn an IKEA Pumpkin LED lamp into a distance sensing prop that plays music and sound effects!

In this project, you'll setup an Apple Shortcut to use Base64 encoding to send a photo to your Adafruit IO feed. A Qualia S3 running CircuitPython code will retrieve the photo from the feed using MQTT, decode it and show it on a beautiful 720x720 round display. Experiment with different photo sets and filters to create your perfectly curated digital photo display.

RP2350 flies high with the Feather format - now you can use any FeatherWings with this battery-powered dev board. It comes with 8MB of flash, 22pin HSTX output port, Stemma QT, debug SWD, and optional PSRAM spot. It's our first RP2350 board and we crammed a ton of goodies into our classic Feather format. It's an excellent starter board to go along with your Pico 2.

This is a DS2482S-800 Stemma QT board that uses a I2C-to-1W controller chip, with 8 selectable channels, built-in parasitic-power-pullups, adjustable I2C address and a wide operating voltage range! You can easily connect it to an existing I2C bus and then use the breakout pads to attach multiple DS18B20's, or pair it with 1-Wire chaining breakouts for fancier experimentation.

Bring your RS232 gear into modern times by adding BLE support. In this project, you'll use an ESP32-S3 Feather running CircuitPython to connect to the Adafruit Bluefruit Connect app over BLE. The control pad in the app will send commands over UART to the RS232 breakout, letting you wirelessly control your RS232 device.

What a cutie pie! Or is it... a QT Py? This diminutive dev board features the powerful CH32V203 low-cost processor that's all the trend: based on RISC-V and cheaper than an 8-bit core! This little one is a great way to get started in the CH32x processor family, with everything you need to build many USB-based projects at an excellent price.

The ESP32-C6 is Espressif's first WiFi 6 SoC integrating 2.4 GHz WiFi 6, Bluetooth 5 (LE) and the 802.15.4 protocol. We took our Feather ESP32-S2 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, NeoPixel, I2C Stemma QT port, and a second low-quiescent LDO for disabling the I2C and NeoPixel when we want ultra-low power usage.
