Questions
How big is the Keyboard PCB?
It measures 90 × 73 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
24 parts, built around the 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 DamianDev123/Hacking_a_Keyboard repository on GitHub, at the commit this page was made from: the board is PCB/Keyboard.kicad_pcb and its schematic PCB/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 DamianDev123 before reusing the design.
