New Guide: Kitty Toe Bean Keypad
Build the cutest four-button mechanical keypad with the Adafruit QT Py RP2040 and a 1.54in TFT display. Using CircuitPython, you can turn this into a USB macro pad or a MIDI controller.
Designed to look like a kitty paw, this four-button keypad is 3D printed and uses mechanical key switches. Featuring key cap “Toe Beans”, this little project is paired nicely with one of Adafruit’s cutest dev boards.
The 1.54in TFT screen displays an animated bitmap of the infamous Party Parrot and advances a frame each time a key is pressed. The buttons can be mapped to MIDI notes and keyboard shortcuts, making this fully customizable.
The QT Py RP2040 is perfect for projects that need a display and a few key switches. The enclosure is 3D printed with parts that snap fit together.
