Questions
How big is the Psu PCB?
It measures 100 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Psu use?
129 parts, built around the S1D, MMBT3904, BC856 and PMP4201Y. 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 Psu KiCad files?
From the kitspace-forks/e100a repository on GitHub, at the commit this page was made from: the board is Proj-Main/psu.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Psu design in my own project?
Its repository states no licence, so its author keeps all rights: ask kitspace-forks before reusing the design.
