Questions
How big is the Power PCB?
It measures 86.5 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power use?
50 parts, built around the NXE2S0505MC-R7, NMJ0515SC and LD1117S33TR(MS). 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 KiCad files?
From the Joe-Purvis/Power repository on GitHub, at the commit this page was made from: the board is Power.kicad_pcb and its schematic ISO_3v3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power design in my own project?
Its repository states no licence, so its author keeps all rights: ask Joe-Purvis before reusing the design.
