Questions
How big is the Keyboard PCB?
It measures 766.5 × 218 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
377 parts, built around the SN74AHCT125N, ESP32-S3-DEVKITC-1-N8R2 and WS2812B. 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 Sidak08/Keyboard repository on GitHub, at the commit this page was made from: the board is Keyboard/main.kicad_pcb and its schematic Keyboard-test/Keyboard.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 Sidak08 before reusing the design.

1) Along with using with TMC2209 motor drivers, I have removed R8, R15, R16, R17, R18, R19 because the R value was accidentally too high. I have shorted R8, R16, R17, and left open R15, R18, R19.
