Questions
How big is the Msm2 PCB?
It measures 150 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Msm2 use?
77 parts, built around the CH340C, AMS1117-3.3 and CR2032. 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 Msm2 KiCad files?
From the Kiviak/stm429 repository on GitHub, at the commit this page was made from: the board is msm2.kicad_pcb and its schematic io.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Msm2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kiviak before reusing the design.
