Questions
How big is the CH340C PCB?
It measures 24 × 17 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CH340C use?
20 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 CH340C KiCad files?
From the upsidedownlabs/Candy-UART repository on GitHub, at the commit this page was made from: the board is CH340C/CH340C.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CH340C design in my own project?
Its repository states no licence, so its author keeps all rights: ask upsidedownlabs before reusing the design.
