Questions
How big is the Power Module PCB?
It measures 105 × 44.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power Module use?
30 parts, built around the TPS62162DSGR, SC0917, AO3400A and BH123A. 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 Module KiCad files?
From the maxbmorr/PCB-Junior_Design repository on GitHub, at the commit this page was made from: the board is Power_Module/Power_Module.kicad_pcb and its schematic Power_Module/Power_Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask maxbmorr before reusing the design.
