Questions
How big is the BT BAT CNTLR PCB?
It measures 145 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BT BAT CNTLR use?
89 parts, built around the AP22814AW5, SN74LVC1T45DRL, LM1117DT-ADJ and PE-92114KNL. 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 BT BAT CNTLR KiCad files?
From the NateJ892/bluetooth-battery-system repository on GitHub, at the commit this page was made from: the board is BT_BAT_CNTLR/BT_BAT_CNTLR.kicad_pcb and its schematic BT_BAT_CNTLR/BT_BAT_CNTLR.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BT BAT CNTLR design in my own project?
Its repository states no licence, so its author keeps all rights: ask NateJ892 before reusing the design.
