Questions
How big is the M4 PCB?
It measures 57.3 × 105 mm and has 2 copper layers, 1.6 mm thick.
What parts does the M4 use?
182 parts, built around the OPA171AID, OPA4171AID, 74ACT541PC and CD4051. 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 M4 KiCad files?
From the minisystem/M4 repository on GitHub, at the commit this page was made from: the board is M4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the M4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask minisystem before reusing the design.
