Questions
How big is the Keyboard PCB?
It measures 162.4 × 124.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
99 parts, built around the ATMEGA32U4. 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 davvdf/Macropad repository on GitHub, at the commit this page was made from: the board is layout/keyboard.kicad_pcb and its schematic macropad/macropad.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 davvdf before reusing the design.
