Open-Source keyboard PCB designs for the Cosmos Keyboard Generator
This repository contains the sources and specs for the PCBs I've made for my pet project, Cosmos Keyboard Generator.
A single-key PCB, with hotswap and RGB support that locks into place. [Main Website] [Buy]
It's similar in functionality to the Amoeba PCBs (in fact I've used some of the same footprints), but I've switched to large SMD pads to make wiring easier and designed the footprint to twist into a custom socket.
