Questions

How big is the RPS ATX PCB?

It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.

What parts does the RPS ATX use?

75 parts, built around the LM358, TL494 and AO3400A. 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 RPS ATX KiCad files?

From the Aborav/PCB_RPS repository on GitHub, at the commit this page was made from: the board is RPS_ATX.kicad_pcb and its schematic RPS_ATX.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the RPS ATX design in my own project?

Its repository states no licence, so its author keeps all rights: ask Aborav before reusing the design.
