Questions
How big is the Foc pcb PCB?
It measures 16.6 × 16.6 mm and has 4 copper layers, 1.69 mm thick.
What parts does the Foc pcb use?
35 parts, built around the DRV8313PWPR, 1N5819HW-7-F-01, LM317LCPK and UWT1V101MCL1GS. 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 pcb KiCad files?
From the avaninder/GimbalFOC repository on GitHub, at the commit this page was made from: the board is foc_pcb/foc_pcb.kicad_pcb and its schematic foc_pcb/foc_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Foc pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask avaninder before reusing the design.
