Questions
How big is the LightPowerBank PCB?
It measures 49.5 × 35.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LightPowerBank use?
37 parts, built around the ATTINY202-SSN, AL8860MP, BQ25895RTW and SM5817PL-TP. 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 LightPowerBank KiCad files?
From the Pegoku/LightPowerBank repository on GitHub, at the commit this page was made from: the board is PCB/PCB.kicad_pcb and its schematic PCB/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LightPowerBank design in my own project?
Its repository states no licence, so its author keeps all rights: ask Pegoku before reusing the design.
