Questions
How big is the Usb hub PCB?
It measures 55.9 × 30.2 mm and has 4 copper layers, 0.8 mm thick.
What parts does the Usb hub use?
66 parts, built around the USBLC6-4. 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 KiCad files?
From the Dygmalab/neuron repository on GitHub, at the commit this page was made from: the board is usb-hub.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb hub design in my own project?
Its repository states no licence, so its author keeps all rights: ask Dygmalab before reusing the design.
