Questions
How big is the NEW PSU PCB?
It measures 188.3 × 93 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NEW PSU use?
26 parts, built around the L7805, L7812, L7912 and 100UF 35V 8*12白高频. 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 NEW PSU KiCad files?
From the Chip90125/PSU repository on GitHub, at the commit this page was made from: the board is NEW PSU.kicad_pcb and its schematic ET_PS.kicad.kicad_sch1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NEW PSU design in my own project?
Its repository states no licence, so its author keeps all rights: ask Chip90125 before reusing the design.
