Questions
What parts does the Bms use?
28 parts, built around the BD48L32G-TL, SN74HC08DR(LX) and B5B-XH-AM. 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 IllinoisRoboticsInSpace/IRIS_PCB repository on GitHub, at the commit this page was made from: the board is boards/Battery Management System/bms2/bms.kicad_pcb and its schematic boards/12V_Power_System/12V_Power_System.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 IllinoisRoboticsInSpace before reusing the design.
