Questions
How big is the CH340-USBC PCB?
It measures 40 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CH340-USBC use?
17 parts, built around the CH340C. 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-USBC KiCad files?
From the iamtwz/Type-C-USB2TTL repository on GitHub, at the commit this page was made from: the board is CH340-USBC.kicad_pcb and its schematic CH340-USBC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CH340-USBC 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).
