Questions
How big is the ATX PCB?
It measures 44.2 × 28 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ATX use?
16 parts, built around the G3VM-601AY2. 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 ATX KiCad files?
From the raaymax/pc-power-controller repository on GitHub, at the commit this page was made from: the board is board/ATX.kicad_pcb and its schematic board/ATX.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ATX design in my own project?
Its repository states no licence, so its author keeps all rights: ask raaymax before reusing the design.
