Questions
How big is the KiCAD BMS EK AW PCB?
It measures 60 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KiCAD BMS EK AW use?
35 parts, built around the BQ76925PW. 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 KiCAD BMS EK AW KiCad files?
From the Flying-team-KTH/Solfar repository on GitHub, at the commit this page was made from: the board is BMS/KiCAD_BMS_EK_AW/KiCAD_BMS_EK_AW.kicad_pcb and its schematic BMS/KiCAD_BMS_EK_AW/KiCAD_BMS_EK_AW.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KiCAD BMS EK AW design in my own project?
Its repository states no licence, so its author keeps all rights: ask Flying-team-KTH before reusing the design.
