Questions
How big is the USB2XXX PCB?
It measures 58.7 × 34.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USB2XXX use?
63 parts, built around the CH340E, TJA1051T/3/1, SL2.1S and BV05C. 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 USB2XXX KiCad files?
From the gdut-dynamic-x/rm_USB2XXX repository on GitHub, at the commit this page was made from: the board is USB2XXX.kicad_pcb and its schematic DBUS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB2XXX design in my own project?
Its repository states no licence, so its author keeps all rights: ask gdut-dynamic-x before reusing the design.
