Questions
How big is the Keyboard PCB?
It measures 330 × 140 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
169 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 mrmaisur/keyboardproj 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 mrmaisur before reusing the design.
