Questions
What parts does the Example4 use?
29 parts, built around the RP2040, W25Q128JVSIQ, AMS1117-3.3 and TS-1088-AR02016. 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 Example4 KiCad files?
From the irampton/Schrune_Examples repository on GitHub, at the commit this page was made from: the board is example4/KiCad/example4.kicad_pcb and its schematic example3/KiCad/example3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Example4 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
