Questions
How big is the Stupid FOCer PCB?
It measures 104.6 × 60 mm and has 2 copper layers, 1 mm thick.
What parts does the Stupid FOCer use?
184 parts, built around the STM32F405RGT6, DRV8301DCA, AMS1117-3.3 and TP2604-SR. 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 Stupid FOCer KiCad files?
From the Old-Nick-99/Simplified_CheapFOCer repository on GitHub, at the commit this page was made from: the board is Stupid_FOCer.kicad_pcb and its schematic CAN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stupid FOCer design in my own project?
Its repository states no licence, so its author keeps all rights: ask Old-Nick-99 before reusing the design.
