Questions
How big is the Keyboard PCB?
It measures 319.5 × 129 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
268 parts, built around the 1N4148WT and BSS138. 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 qwel-exe/keyboard repository on GitHub, at the commit this page was made from: the board is keyboard.kicad_pcb and its schematic 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 qwel-exe before reusing the design.
