Questions
How big is the Usbhub01a PCB?
It measures 80.8 × 80.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Usbhub01a use?
145 parts, built around the TUSB8041IPAPRQ1, TPS2001CDGN, AP2281-1WG and TPS74801RGWR. 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 Usbhub01a KiCad files?
From the mlab-modules/USBHUB01 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/usbhub01a.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usbhub01a design in my own project?
Its repository states no licence, so its author keeps all rights: ask mlab-modules before reusing the design.
