Questions
How big is the Task3 USB Serial CH340G PCB?
It measures 60 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Task3 USB Serial CH340G use?
13 parts, built around the CH340G and USBLC6-2SC6. 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 Task3 USB Serial CH340G KiCad files?
From the Assane401/Task3_USB_Serial_CH340G repository on GitHub, at the commit this page was made from: the board is Task3_USB_Serial_CH340G.kicad_pcb and its schematic Task3_USB_Serial_CH340G.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Task3 USB Serial CH340G design in my own project?
Its repository states no licence, so its author keeps all rights: ask Assane401 before reusing the design.
