My split keyboard is a Corne like wired split keyboard. It uses QMK firmware
It serves as a split keyboard that I can use to type on without getting sore quickly.
Features:
- 42 Hot-swappable keys
- 3 Thumb keys on each side
- A TRRS cable for the two different parts to communicate
- VIA support
- Doesn't need a case, only a PCB
PCB:
My PC was made in Kicad

Questions
How big is the Pyae s Split PCB?
It measures 338.1 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pyae s Split use?
88 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 Pyae s Split KiCad files?
From the Pyae2014K/Pyae-s-Split repository on GitHub, at the commit this page was made from: the board is PCB/Pyae's Split.kicad_pcb and its schematic PCB/Pyae's Split.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pyae s Split design in my own project?
Its repository states no licence, so its author keeps all rights: ask Pyae2014K before reusing the design.
