Questions
How big is the Macropad PCB?
It measures 78.7 × 86.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
30 parts, built around the ATMEGA32U4-AUR. 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 Ahan-Goel/macropad repository on GitHub, at the commit this page was made from: the board is PCB Files/Macro Pad.kicad_pcb and its schematic PCB Files/Macro Pad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
