Questions

What parts does the F MOMM use?

89 parts, built around the CC0402KRX7R7BB104. 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 F MOMM KiCad files?

From the o7-machinehum/F-MOMM repository on GitHub, at the commit this page was made from: the board is electronics/board/hardware.kicad_pcb and its schematic electronics/board/ddr3_a.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the F MOMM design in my own project?

Its repository states no licence, so its author keeps all rights: ask o7-machinehum before reusing the design.
