Questions
How big is the Qwiic hub PCB?
It measures 22.8 × 15.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Qwiic hub use?
10 parts. 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 Qwiic hub KiCad files?
From the zapta/greenpak_misc repository on GitHub, at the commit this page was made from: the board is qwiic_hub/qwiic_hub.kicad_pcb and its schematic qwiic_hub/qwiic_hub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Qwiic hub design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
