Questions
How big is the Macropad Group Project PCB?
It measures 86.5 × 54.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad Group Project use?
34 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 Macropad Group Project KiCad files?
From the A197367/Macropad-Group-Project repository on GitHub, at the commit this page was made from: the board is Macropad Group Project.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad Group Project 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).
