Questions
How big is the MA Command Keyboard PCB?
It measures 195.3 × 209.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MA Command Keyboard use?
165 parts, built around the ATMEGA32U4-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 MA Command Keyboard KiCad files?
From the dvdcd/MA-Command-Keyboard repository on GitHub, at the commit this page was made from: the board is MA Command Keyboard.kicad_pcb and its schematic MA Command Keyboard changed footprint.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MA Command Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask dvdcd before reusing the design.
