Questions
How big is the Keyboard PCB?
It measures 257.7 × 114.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
122 parts, built around the ATMEGA32U4. 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 Keyboard KiCad files?
From the sendz/minix-keyboard repository on GitHub, at the commit this page was made from: the board is keyboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask sendz before reusing the design.
