Questions
How big is the Usb hub PCB?
It measures 70 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb hub use?
18 parts, built around the CH334R. 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 Usb hub KiCad files?
From the k1wizz/usb-hub repository on GitHub, at the commit this page was made from: the board is pcb/usb_hub.kicad_pcb and its schematic pcb/usb_hub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb hub design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
