Questions
How big is the Bms PCB?
It measures 103.1 × 71.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Bms use?
236 parts, built around the SN65HVD232D, LMR36510ADDA, MAX17614ATP+ and BQ25756RRVR. 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 Bms KiCad files?
From the membaye/bms repository on GitHub, at the commit this page was made from: the board is bms.kicad_pcb and its schematic bms.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bms design in my own project?
Its repository states no licence, so its author keeps all rights: ask membaye before reusing the design.
