Questions
How big is the MMv3 PCB?
It measures 69 × 72 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MMv3 use?
47 parts, built around the DRV8833LPWP, DRV8833RTYR, DS28E05R+T and DMG2302U. 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 MMv3 KiCad files?
From the MrCroesus/MMv3 repository on GitHub, at the commit this page was made from: the board is board/MMv3.kicad_pcb and its schematic board/MMv3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MMv3 design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
