Questions
How big is the LipoCharger PCB?
It measures 38.1 × 11.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LipoCharger use?
15 parts, built around the TP4056-42-ESOP8. 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 LipoCharger KiCad files?
From the EthanGreenhouse/learn repository on GitHub, at the commit this page was made from: the board is kicad/lipoCharger/lipoCharger.kicad_pcb and its schematic kicad/buckConverter/buckConverter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LipoCharger design in my own project?
Its repository states no licence, so its author keeps all rights: ask EthanGreenhouse before reusing the design.
