Questions
How big is the Usb hub tutorial PCB?
It measures 40 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb hub tutorial use?
22 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 tutorial KiCad files?
From the tobycm/usb-hub-tutorial repository on GitHub, at the commit this page was made from: the board is usb-hub-tutorial.kicad_pcb and its schematic usb-hub-tutorial.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb hub tutorial 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).
