Questions
How big is the ChargerOnly PCB?
It measures 40 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ChargerOnly use?
62 parts, built around the CSD17309Q3. 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 ChargerOnly KiCad files?
From the bentwire/SB-4S5A repository on GitHub, at the commit this page was made from: the board is ChargerOnly.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ChargerOnly design in my own project?
Its repository states no licence, so its author keeps all rights: ask bentwire before reusing the design.
