Questions
How big is the APRL BMS DEV PCB PCB?
It measures 160 × 80.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the APRL BMS DEV PCB use?
74 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 APRL BMS DEV PCB KiCad files?
From the d8yu/BMS_DEV_PCB repository on GitHub, at the commit this page was made from: the board is PCB/APRL_BMS_DEV_PCB.kicad_pcb and its schematic PCB/APRL_BMS_DEV_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the APRL BMS DEV PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask d8yu before reusing the design.
