Questions
How big is the Bms active hw PCB?
It measures 108 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bms active hw use?
136 parts, built around the ESP32-WROOM-32, INA282AID, LM358 and LM5010AMH. 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 active hw KiCad files?
From the NGOQUOC98/ESP32_PCB repository on GitHub, at the commit this page was made from: the board is bms-active-hw.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bms active hw design in my own project?
Its repository states no licence, so its author keeps all rights: ask NGOQUOC98 before reusing the design.
