Questions

How big is the Pcb batterypack PCB?

It measures 91 × 55 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Pcb batterypack use?

16 parts, built around the TX08F103F3435ER. 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 Pcb batterypack KiCad files?

From the EffectiveRange/pcb-batterypack repository on GitHub, at the commit this page was made from: the board is pcb-batterypack.kicad_pcb and its schematic pcb-batterypack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pcb batterypack design in my own project?

Its repository states no licence, so its author keeps all rights: ask EffectiveRange before reusing the design.
