Questions
What parts does the CH340 use?
11 parts, built around the CH340G. 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 CH340 KiCad files?
From the bask185/general_schematics repository on GitHub, at the commit this page was made from: the board is CH340/CH340.kicad_pcb and its schematic CDU/CDU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CH340 design in my own project?
Its repository states no licence, so its author keeps all rights: ask bask185 before reusing the design.
