Questions
How big is the SinglePowerBank PCB?
It measures 95 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SinglePowerBank use?
16 parts, built around the ETA9638E8A. 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 SinglePowerBank KiCad files?
From the BearLaboratory/SinglePowerBank repository on GitHub, at the commit this page was made from: the board is SinglePowerBank.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SinglePowerBank design in my own project?
Its repository publishes it under the GPL-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).
