Questions
How big is the MacroBoy PCB?
It measures 81.1 × 95.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MacroBoy use?
68 parts, built around the ATMEGA32U4-AU and WS2812B. 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 MacroBoy KiCad files?
From the JoeTot/kbmacro repository on GitHub, at the commit this page was made from: the board is MacroBoy.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MacroBoy design in my own project?
Its repository states no licence, so its author keeps all rights: ask JoeTot before reusing the design.
