Questions
How big is the Mspm0-mini PCB?
It measures 50 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mspm0-mini use?
38 parts, built around the MSPM0G3507SPTR, CH340E, LIS2DH and SPX3819M5-L-3-3. 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 Mspm0-mini KiCad files?
From the bfmhno3/mspm0-mini repository on GitHub, at the commit this page was made from: the board is mspm0-mini.kicad_pcb and its schematic mspm0-mini.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mspm0-mini 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).
