README
README.mdNote, this is not the hardware version of the "Lite"-version of the FlexiBMS, but an earlier tested and discontinued/abandoned concept of the BMS design. Lite HW is a new project that was started after this HW project was discontinued and is not currently in open-source circulation HW design wise.

Questions
How big is the FlexiBMS PCB?
It measures 65 × 35 mm and has 4 copper layers, 1.6 mm thick.
What parts does the FlexiBMS use?
209 parts, built around the STM32L433CCT6, TCAN330D, MAX5215GUA+ and ISL28022FUZ. 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 FlexiBMS KiCad files?
From the SimosMCmuffin/FlexiBMS_hardware repository on GitHub, at the commit this page was made from: the board is FlexiBMS.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FlexiBMS design in my own project?
Its repository states no licence, so its author keeps all rights: ask SimosMCmuffin before reusing the design.
