Questions
How big is the CH341A Pro PCB?
It measures 27.5 × 69 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CH341A Pro use?
18 parts, built around the CH341A and AMS1117-3.3. 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 CH341A Pro KiCad files?
From the Upcycle-Electronics/CH341A-Pro repository on GitHub, at the commit this page was made from: the board is CH341Apro.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CH341A Pro design in my own project?
Its repository states no licence, so its author keeps all rights: ask Upcycle-Electronics before reusing the design.
