Questions
How big is the Fm2 PCB?
It measures 110 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Fm2 use?
120 parts, built around the BGU7045, 74LVC1G80GW, LMP7731MF and TLC2932AIPW. 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 Fm2 KiCad files?
From the jvok94/u235 repository on GitHub, at the commit this page was made from: the board is fm2/fm2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fm2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jvok94 before reusing the design.
