Questions
How big is the Bms module PCB?
It measures 34.5 × 18.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bms module use?
11 parts. 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 module KiCad files?
From the ashwin-k8/ashwin-k8.github.io repository on GitHub, at the commit this page was made from: the board is projects/bms-module/bms module.kicad_pcb and its schematic projects/MINI MOTOR CONTROLER/esp32_mini_motor_deiver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bms module design in my own project?
Its repository states no licence, so its author keeps all rights: ask ashwin-k8 before reusing the design.
