Questions

How big is the Charger2 PCB?

It measures 100 × 200 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Charger2 use?

169 parts, built around the 74LVC1G17Z, TP4056, 74HC4052 and 74HC4050D. 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 Charger2 KiCad files?

From the alangecker/yacharger repository on GitHub, at the commit this page was made from: the board is hw/charger2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Charger2 design in my own project?

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