Questions
How big is the Power bank PCB PCB?
It measures 69.5 × 36.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power bank PCB use?
99 parts, built around the TPS63070RNMR, DW01A, TP4056-42-ESOP8 and TPS61022. 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 Power bank PCB KiCad files?
From the Wudker/Solarbank repository on GitHub, at the commit this page was made from: the board is Hardware/PCB/Power_bank_PCB/Power_bank_PCB.kicad_pcb and its schematic Hardware/PCB/Power_bank_PCB/Power_bank_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power bank PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Wudker before reusing the design.
