Questions
What parts does the Example3 use?
22 parts, built around the TPS54331DR-JSM, AMS1117-3.3, 2.54-1*3P针 and PJ-002BH. 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 Example3 KiCad files?
From the irampton/Schrune_Examples repository on GitHub, at the commit this page was made from: the board is example3/KiCad/example3.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 Example3 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).
