Questions
How big is the Backplane PSU PCB?
It measures 150 × 160 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Backplane PSU use?
56 parts. 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 Backplane PSU KiCad files?
From the SesameEngineering/Projects repository on GitHub, at the commit this page was made from: the board is Discovery/Electrical/Redundant Discovery/Backplane PSU/Backplane PSU.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Backplane PSU design in my own project?
Its repository states no licence, so its author keeps all rights: ask SesameEngineering before reusing the design.
