Questions
How big is the External PCB?
It measures 45 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the External use?
58 parts, built around the STSPIN32F0, RS485, LM5019MR and PSMN3R3-40YS. 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 External KiCad files?
From the mkramar/dizzyrobot repository on GitHub, at the commit this page was made from: the board is Schamatic/Motor/external.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the External design in my own project?
Its repository states no licence, so its author keeps all rights: ask mkramar before reusing the design.
