Questions
How big is the Portable power source PCB?
It measures 56 × 42.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Portable power source use?
37 parts, built around the TP4056, TPS63802DLA, 1N5819WS and SI2301CDS. 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 Portable power source KiCad files?
From the Catalysxt/hazard repository on GitHub, at the commit this page was made from: the board is portable_power_source.kicad_pcb and its schematic 18650 battery holder/18650_battery_holder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Portable power source design in my own project?
Its repository states no licence, so its author keeps all rights: ask Catalysxt before reusing the design.
