Questions
How big is the Atkeyboard PCB?
It measures 112 × 62 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atkeyboard use?
80 parts, built around the ATMEGA328P-AU and ADXL345-EP. 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 Atkeyboard KiCad files?
From the ccadic/atmega328kb repository on GitHub, at the commit this page was made from: the board is atkeyboard/atkeyboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atkeyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask ccadic before reusing the design.
