Questions
How big is the Keyboard PCB?
It measures 344 × 79.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
284 parts, built around the 74AHCT125D and 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 Keyboard KiCad files?
From the NMaster23/Keyboard repository on GitHub, at the commit this page was made from: the board is PCB/PCB.kicad_pcb and its schematic PCB/PCB.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 publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
