Questions
How big is the Mswi PCB?
It measures 140 × 178.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mswi use?
154 parts, built around the ATMEGA328PB-AU, MCP2551-I/SN, LM1117-5.0 and BC856. 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 Mswi KiCad files?
From the ZeniteSolar/MSWI19 repository on GitHub, at the commit this page was made from: the board is pcb/mswi/mswi.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mswi design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
