Questions
How big is the Custom Keyboard PCB?
It measures 293.2 × 154.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Custom Keyboard use?
274 parts, built around the SK6812MINI-E. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Custom Keyboard KiCad files?
From the Jay-Tai/Custom-Keyboard repository on GitHub, at the commit this page was made from: the board is pcb/Custom Keyboard.kicad_pcb and its schematic pcb/Custom Keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Custom Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jay-Tai before reusing the design.
