Questions

How big is the Atx PCB?

It measures 170 × 170 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Atx use?

62 parts, built around the STM32L151C8T6 and SS-74500-024. 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 aep/pislice repository on GitHub, at the commit this page was made from: the board is atx/atx/atx.kicad_pcb. 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 aep before reusing the design.
