Questions
How big is the Usbhub PCB?
It measures 17.8 × 16.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usbhub use?
26 parts, built around the USB2422/MJ. 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 Usbhub KiCad files?
From the znuh/pcbs repository on GitHub, at the commit this page was made from: the board is usbhub/usbhub.kicad_pcb and its schematic ft234_buffered/ft234.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usbhub design in my own project?
Its repository states no licence, so its author keeps all rights: ask znuh before reusing the design.
