Questions
How big is the BMS 02 PCB?
It measures 96.7 × 175.6 mm and has 4 copper layers, 1.59 mm thick.
What parts does the BMS 02 use?
621 parts, built around the ACS72981LLRATR-100B5, CT415-HSN820DR, FAN3216TMX-F085 and FT231XS-R. 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 02 KiCad files?
From the Voltworks-Garage/Hardware repository on GitHub, at the commit this page was made from: the board is PCBAs/BMS/BMS_02/BMS_02.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BMS 02 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
