Questions
How big is the 3S BMS PCB?
It measures 41 × 60.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 3S BMS use?
53 parts. 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 3S BMS KiCad files?
From the Sasasu/3S_BMS repository on GitHub, at the commit this page was made from: the board is 3S电池保护版.kicad_pcb and its schematic 3S电池保护版.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 3S BMS design in my own project?
Its repository states no licence, so its author keeps all rights: ask Sasasu before reusing the design.
