Questions
How big is the Keyboard PCB?
It measures 240.3 × 76 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
84 parts. 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 KITTY-6502/hardware repository on GitHub, at the commit this page was made from: the board is Kicad/keyboard/keyboard/keyboard.kicad_pcb and its schematic Kicad/case/back/back.kicad_sch. 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 KITTY-6502 before reusing the design.
