Questions
How big is the PowerPCB PCB?
It measures 82.3 × 55.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PowerPCB use?
76 parts, built around the FS1403-5000-AL and TPS551892QWRYQRQ1. 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 PowerPCB KiCad files?
From the try-except/TitoSync repository on GitHub, at the commit this page was made from: the board is PowerPCB/PowerPCB.kicad_pcb and its schematic ActiveLoad/ActiveLoadPCB/ActiveLoadPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PowerPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask try-except before reusing the design.
