Questions
How big is the FOC Motor Controller Dev Board PCB?
It measures 189.5 × 130.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FOC Motor Controller Dev Board use?
39 parts, built around the STM32G431CBU6, DRV8316CRRGFR and SS34. 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 Motor Controller Dev Board KiCad files?
From the AjaxAttack/FOC-Motor-Control-Dev-Board repository on GitHub, at the commit this page was made from: the board is FOC Motor Controller Dev Board.kicad_pcb and its schematic FOC Motor Controller Dev Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FOC Motor Controller Dev Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask AjaxAttack before reusing the design.
