Questions
How big is the Split keeb PCB?
It measures 254.2 × 112.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Split keeb use?
140 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 Split keeb KiCad files?
From the Midnight-crown/Split_Keyboard repository on GitHub, at the commit this page was made from: the board is PCB/Split_keeb.kicad_pcb and its schematic PCB/Split_keeb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Split keeb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Midnight-crown before reusing the design.
