663 open source boards in Keyboards
Mechanical keyboard PCBs, split boards and macropads — QMK, ZMK, MX and Choc. Every board here is a public GitHub project with its KiCad files, read for size, layers and parts. Pick one close to your design and simulate its firmware on HardLabs before you build it.
