Raspberry Pi Pico 18-Key Macro Pad

thingiverse

This is a macropad inspired by novaspirit's Raspberry Pi Pico Macro Keys! Although the design is original, the idea and the code were both sourced from their project : ) This macropad is a great introduction into programming and soldering. Follow the guide on https://www.tomshardware.com/how-to/raspberry-pi-pico-powered-stream-deck to for example wiring and software. Sample code has been provided - all you need to do is fill in the brackets in the keyboard.send() sections of the code with your desired keystrokes. Keycodes can be found here: https://circuitpython.readthedocs.io/projects/hid/en/latest/_modules/adafruit_hid/keycode.html I've also uploaded the Fusion 360 file so that you can make any changes you'd like to. WARNING: My code and model are both sloppy... Leave any suggestions in the comments : ) Parts List: - 18 cherry style mechanical key switches - raspberry pi pico - wires *no glue or screws required! all parts friction fit together* Assembly: - Print keycaps, frame, and switch plate - snap all switches into the plate - solder a common wire between one pin on each switch - solder a wire between the 3v3 pin on the pico and the power bus on the key matrix - solder the remaining pins of the switches to an individual gp pin on the pico (I've used gp0-17, but you can use any - just change it in the code) - snap the pico onto the standoffs in the frame - slide the switch plate into the frame
