Questions
How big is the Overkeyboard PCB?
It measures 531.8 × 198.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Overkeyboard use?
340 parts, built around the AT90USB1286-AU. 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 Overkeyboard KiCad files?
From the SicklySilverMoon/Overkeyboard repository on GitHub, at the commit this page was made from: the board is Overkeyboard.kicad_pcb and its schematic Overkeyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Overkeyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask SicklySilverMoon before reusing the design.
