Questions
How big is the Foc PCB?
It measures 60 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Foc use?
71 parts, built around the INA240A1PW, EG2133, SX1308 and LP5907MFX-3.3. 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 Foc KiCad files?
From the CodonNine/foc repository on GitHub, at the commit this page was made from: the board is Hardware/hardware.kicad_pcb and its schematic Hardware/Bridge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Foc design in my own project?
Its repository states no licence, so its author keeps all rights: ask CodonNine before reusing the design.
