Questions

How big is the Coinbat charger PCB?

It measures 39.4 × 52.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Coinbat charger use?

14 parts, built around the MCP73831, B130LAW and DMP1045U. 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 Coinbat charger KiCad files?

From the ccadic/coincellcharger repository on GitHub, at the commit this page was made from: the board is coinbat_charger.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Coinbat charger design in my own project?

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