Questions
How big is the Smarthub PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smarthub use?
101 parts, built around the FSUSB31K8X, MIC2026-2BM-TR, MIC5219-3.3YMM and USB2517-JZX. 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 Smarthub KiCad files?
From the EnJens/smarthub repository on GitHub, at the commit this page was made from: the board is hw/smarthub.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smarthub design in my own project?
Its repository states no licence, so its author keeps all rights: ask EnJens before reusing the design.
