The Ground Control 40 Dev Board is an open-source 40% ortholinear keyboard shell with exposed pin header, designed by Nick Coughlin aka ncoughlin/NC_Developer for rapid prototyping with any microcontroller of your choice.
Features
- 45 keys (12x4-ish)
- split spacebar ortholinear 40% layout
- low-profile (Choc v1), hotswap
- folded switch matrix to minimize required I/O pins
- combined rotary encoder + 5-direction multiswitch in one (Alps RKJXT1F42001)
The row, column and encoder pins are exposed with a 1x20 socket to easily connect anything to a breadboard.
