Questions
How big is the MM8108-Dev Kit PCB?
It measures 26.4 × 39.2 mm and has 2 copper layers, 1.63 mm thick.
What parts does the MM8108-Dev Kit use?
32 parts, built around the AP3401 and MM8108-MF15457. 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 MM8108-Dev Kit KiCad files?
From the CSutter5/MM8108-Dev-Kit repository on GitHub, at the commit this page was made from: the board is MM8108-Dev-Kit.kicad_pcb and its schematic MM8108-Dev-Kit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MM8108-Dev Kit 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).
