Questions
How big is the M1-ubmc PCB?
It measures 32.4 × 52.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the M1-ubmc use?
46 parts, built around the FUSB302BMPX, RS2227XN, TLV70212DBVR(MS) and AO3400A. 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 M1-ubmc KiCad files?
From the kernelorg-mirror/linux_kernel_git_maz_cs-hw repository on GitHub, at the commit this page was made from: the board is m1-ubmc.kicad_pcb and its schematic jig/jig.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the M1-ubmc 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).
