Questions
How big is the PowerPack PCB?
It measures 45.6 × 25 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PowerPack use?
51 parts, built around the TPS2121RUXR. 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 PowerPack KiCad files?
From the UMDBPP/Rudolph repository on GitHub, at the commit this page was made from: the board is Hardware/PowerPack/PowerPack.kicad_pcb and its schematic Hardware/PowerPack/PowerPack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PowerPack design in my own project?
Its repository states no licence, so its author keeps all rights: ask UMDBPP before reusing the design.
