Questions
What parts does the Hubi use?
63 parts, built around the SL2.1S. 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 Hubi KiCad files?
From the eyalbirger/Hubi repository on GitHub, at the commit this page was made from: the board is kicad/Hubi/Hubi.kicad_pcb and its schematic kicad/Hubi/Hubi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hubi design in my own project?
Its repository states no licence, so its author keeps all rights: ask eyalbirger before reusing the design.
