Questions
How big is the Ch340g dl PCB?
It measures 33 × 17.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ch340g dl use?
16 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 Ch340g dl KiCad files?
From the jk1mly/pcb-ch340c repository on GitHub, at the commit this page was made from: the board is ch340g-dl.kicad_pcb and its schematic ch340g-dl.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ch340g dl design in my own project?
Its repository states no licence, so its author keeps all rights: ask jk1mly before reusing the design.
