README
README.mdCplitzu keyboard
The Cplitzu Keyboard is a compact, ortholinear, 50-key split keyboard inspired by the Let's split and Corne keyboards. It features a 3x6 ortholinear layout with an additional thumb key for improved ergonomics and functionality. Designed with ease of assembly in mind, it avoids the need for tiny SMD components, making it beginner-friendly for hand soldering.

Questions
How big is the Cplitzu PCB?
It measures 303.6 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cplitzu use?
162 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 Cplitzu KiCad files?
From the infiniteoffset/cplitzu repository on GitHub, at the commit this page was made from: the board is pcbs/cplitzu.kicad_pcb and its schematic pcbs/cplitzu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cplitzu design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
