Questions
How big is the M8 PCB?
It measures 50 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the M8 use?
10 parts, built around the CH32V003F4P6, B3F-4000 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 M8 KiCad files?
From the moore/m8 repository on GitHub, at the commit this page was made from: the board is board/m8/m8.kicad_pcb and its schematic board/m8/m8.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the M8 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).
