Questions

How big is the Split PCB?

It measures 42 × 42 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Split use?

12 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 Split KiCad files?

From the ppetr/home-automation-CAN repository on GitHub, at the commit this page was made from: the board is split/split.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Split design in my own project?

Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
