Kitty Paw

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.

Kitty Paw

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.

USB Macros & MIDI

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.

3D Printing & DIY Electronics

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.
