It measures 151 × 148.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Simple split use?

59 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 Simple split KiCad files?

From the gemigtur/split-keyboard repository on GitHub, at the commit this page was made from: the board is pcb_left/simple_split.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Simple split design in my own project?

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