Questions
How big is the BreadboardUPS PCB?
It measures 39.3 × 81 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BreadboardUPS use?
78 parts, built around the TPS630701RNMR, BQ24090DGQR, SS14 and DO2309A. 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 BreadboardUPS KiCad files?
From the Dinamiet/BreadboardBatteryPCB repository on GitHub, at the commit this page was made from: the board is BreadboardUPS.kicad_pcb and its schematic BreadboardUPS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BreadboardUPS design in my own project?
Its repository states no licence, so its author keeps all rights: ask Dinamiet before reusing the design.
