Questions
How big is the Power supply PCB?
It measures 60 × 60 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Power supply use?
104 parts, built around the TPS5430DDA, SS34 and PJ-102AH. 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 supply KiCad files?
From the nullcrimson/power-supply repository on GitHub, at the commit this page was made from: the board is power_supply.kicad_pcb and its schematic power_supply.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power supply design in my own project?
Its repository states no licence, so its author keeps all rights: ask nullcrimson before reusing the design.
