Questions
How big is the Hub PCB?
It measures 72 × 15 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hub use?
18 parts, built around the SL2.1A, 918-118A2021Y40002 and TYPEC-303-ACP16. 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 Hub KiCad files?
From the PythonOrC/USB-HUB-Keyboard repository on GitHub, at the commit this page was made from: the board is source/hub/hub.kicad_pcb and its schematic source/hub/hub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hub design in my own project?
Its repository states no licence, so its author keeps all rights: ask PythonOrC before reusing the design.
