An open source USB to TTL serial adapter
OpenUSB2Serial is an open-source printed circuit board by blark, from the blark/OpenUSB2Serial repository on GitHub. It is a 2-layer board of 20.8 × 33 mm with 13 parts on 23 nets, routed with 125 tracks and 15 vias.
It is built around the CH340C. Its parts include 6 capacitors, 2 resistors, 2 ICs and 2 connectors. It belongs with the interfaces and adapters boards of this library.
An open source USB to serial adapter based on the cheap CH340C IC.
You can get 3 of these boards from Oshpark for $5.35.

13 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.
From the blark/OpenUSB2Serial repository on GitHub, at the commit this page was made from: the board is OpenUSB2Serial.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask blark before reusing the design.
