Questions
How big is the Uhub PCB?
It measures 16 × 13 mm and has 2 copper layers, 0.6 mm thick.
What parts does the Uhub use?
15 parts. 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 Uhub KiCad files?
From the DiodeRed/pocket-usb-intercept repository on GitHub, at the commit this page was made from: the board is uhub.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Uhub design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
