Questions
How big is the BMSv2 PCB?
It measures 44 × 40.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BMSv2 use?
127 parts, built around the AMS1117-3.3, MMBT3904, DMG2301L and AO3401A. 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 BMSv2 KiCad files?
From the Mieho1/BMSv2 repository on GitHub, at the commit this page was made from: the board is BMSv2/BMSv2.kicad_pcb and its schematic BMSv2/BMSv2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BMSv2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mieho1 before reusing the design.
