Questions
How big is the ESC PCB?
It measures 54.5 × 40.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESC use?
57 parts, built around the AP63205WU, DRV8323SRTAT, AMS1117-3.3 and CSD18532Q5B. 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 ESC KiCad files?
From the Kenmaa13/ELECTRONIC-SPEED-CONTROLLER repository on GitHub, at the commit this page was made from: the board is ESC.kicad_pcb and its schematic ESC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESC design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kenmaa13 before reusing the design.
