A simple macro keyboard designed from scratch.
Raspberry Pi Pico running a simple CircuitPython firmware that acts as a USB HID keyboard.
The board offers room for eight Cherry MX compatible switches. Each switch is wired to its own GPIO port on the Pico and all share one common ground connector.
Simple enclosure consisting of a top and bottom half.
Other than the board and the case that can be produced from the designs, following parts are needed:
- 1x Raspberry Pi Pico
- 2x 20 pin short female header
- 8x Cherry MX compatible switch
- 8x Cherry MX compatible keycap
- 4x M3x10 screw
- 4x M3 nut
Keyswitches with fixing pins are recommended (e.g. Cherry MX1A-E1NN), as they make it easier to solder them to the PCB. For switches without fixing pins, the soldering aid included in the case designs can be used to align things evenly.
