Questions
How big is the CH582 PCB?
It measures 30 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CH582 use?
45 parts, built around the PJ4054B. 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 CH582 KiCad files?
From the MWehning/CH582battery repository on GitHub, at the commit this page was made from: the board is CH582.kicad_pcb and its schematic CH582.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CH582 design in my own project?
Its repository states no licence, so its author keeps all rights: ask MWehning before reusing the design.
