Questions
How big is the Keyboard pcb PCB?
It measures 148.3 × 97.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard pcb use?
78 parts, built around the ATMEGA32U4-AU. 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 pcb KiCad files?
From the DisabledBaecon/keyboard-pcb repository on GitHub, at the commit this page was made from: the board is pcb.kicad_pcb and its schematic pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask DisabledBaecon before reusing the design.
