The Adafruit CircuitPython Wii Classic Controller library will let you connect a Wii Classic compatible controller to an Adafruit Wii Nunchuck Breakout Adapter over STEMMA I2C to read the incoming inputs from the controller. 

If you'd like to connect your Feather to a CAN Bus, the Adafruit CAN Bus FeatherWing with MCP2515 controller and TJA1051/3 transceiver will work with any and all Feathers! The controller used is the MCP2515, an extremely popular and well-supported chipset that has drivers in Arduino and CircuitPython and only requires an SPI port and two pins for chip-select and IRQ. Use it to send and receive messages in either standard or extended format at up to 1 Mbps.

If you'd like to connect a board with native CAN Peripheral support, the Adafruit CAN Pal Transceiver will take the 3V logic level signals and convert them to CAN logic levels with the differential signaling required to communicate.

In this project, you'll mount servo motors over the strings of a lyre. The servos will pluck those strings when they receive MIDI NoteOn messages via a Feather RP2040 running CircuitPython. You can control the lyre with an eternal MIDI controller or by sending MIDI out from your favorite DAW program.

Get ready for our fastest Metro ever - the NXP i.MX RT1011 microcontroller powers this board with a 500 MHz ARM Cortex M7 processor. There's 4 MB of execute-in-place QSPI for firmware + disk storage and 128KB of SRAM in-chip.

The PiCowbell Adalogger is the same size and shape as a Pico and is intended to socket underneath to make your next data logging or data reading project super easy. Micro SD card socket? Yes! STEMMA QT / Qwiic connector for fast I2C? Indeed. Real Time Clock with battery backup for accurate timekeeping? Of course!

The Reverse TFT Feather comes with the 240x135 color TFT display on the back-side not the front-side. That makes it great for panel-mounted projects, especially with the included buttons. It's like an all-in-one display interface development board, powered by the fantastic ESP32-S3 WiFi module.

Hobby-level microcontrollers are finally getting powerful enough to start handling camera modules that historically would have required a full computer or FPGA to handle. This breakout board has a nice quality OV5640 camera with a 5 Megapixel sensor element, 120-degree wide angle lens, and all the support circuitry you need

The NeoKey BFF is designed to fit onto the back of any QT Py or Xiao board to build a one-key keyboard. It has a Kailh socket, where you can plug in any MX-compatible switch and it has a reverse mount NeoPixel to light-up your switch.

The microSD Card BFF has a micro SD card slot that can fit on the back of your miniature dev board. It uses the three SPI pins plus one chip select pin to access megs or gigs of data. Onboard is a slim, high quality Molex push-pull micro SD card socket. Since the QT Py is already 3V, no level shifter or regulator is required.

The Reverse TFT Feather comes with the 240x135 color TFT display on the back-side not the front-side. That makes it great for panel-mounted projects, especially with the included buttons. It's like an all-in-one display interface development board, powered by the fantastic ESP32-S2 WiFi module.

You'll use Adafruit IO as an MQTT broker for OctoPrint and CircuitPython. OctoPrint will send MQTT messages to Adafruit IO as individual feeds. The TFT screen displays the status transmitted from OctoPrint. The Feather can also send messages to OctoPrint such as pausing or canceling a print.
