README
README.mdJoeM BMC
Originally called "JoeM BMS" is now called "JoeM BMC" Battery Management Controller. Since it's not a complete BMS but only a controller for existing BMS-Modules. This is the updated version for Teensy 4.0
This project is derived from Toms SimpBMS code. It started as a clone (Software & Hardware) but ended up completely rewritten and redesigned. But you might still find some traces to the original code.
Complete documentation coming soon.

Questions
How big is the JoeM BMC V3.2 PCB?
It measures 68 × 92 mm and has 2 copper layers, 1.6 mm thick.
What parts does the JoeM BMC V3.2 use?
70 parts, built around the SN65HVD230D, IS281-4, BSO615NG and NUP2105L. 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 JoeM BMC V3.2 KiCad files?
From the JoeMudr/JoeMBMC repository on GitHub, at the commit this page was made from: the board is Board/JoeM_BMC_V3.2/JoeM_BMC_V3.2.kicad_pcb and its schematic Board/JoeM_BMC_V3.2/JoeMBMC_V3.1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the JoeM BMC V3.2 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
