Questions

How big is the Splittable keeb PCB?

It measures 376.2 × 170.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Splittable keeb use?

279 parts, built around the SK6812MINI-E. 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 Splittable keeb KiCad files?

From the EpicTromboneKid/split-key repository on GitHub, at the commit this page was made from: the board is splittable-keeb.kicad_pcb and its schematic splittable-keeb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Splittable keeb design in my own project?

Its repository states no licence, so its author keeps all rights: ask EpicTromboneKid before reusing the design.
