Questions
How big is the SplitKbHub PCB?
It measures 23.7 × 66.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SplitKbHub use?
8 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 SplitKbHub KiCad files?
From the semicontinuity/embedded repository on GitHub, at the commit this page was made from: the board is target/split-keyboard-dongle/hardware/SplitKbHub.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SplitKbHub design in my own project?
Its repository states no licence, so its author keeps all rights: ask semicontinuity before reusing the design.
