Questions
How big is the Macropad PCB?
It measures 76 × 176.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
93 parts, built around the ATMEGA32U4 and SK6812. 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 Macropad KiCad files?
From the lf-/reality repository on GitHub, at the commit this page was made from: the board is mechanical-macropad/macropad/macropad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask lf- before reusing the design.
