Questions

How big is the Powerbank pcb PCB?

It measures 17.9 × 64.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Powerbank pcb use?

32 parts, built around the TPS61022. 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 Powerbank pcb KiCad files?

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

Can I use the Powerbank pcb design in my own project?

Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
