The Corne Keyboard is a split ergonomic design that features a 3x6 column staggered layout with a three key thumb cluster. The Corne layout has many distinguishing features that set it apart from other ergonomic keyboards. The small layout keeps all keys within one unit of the home row. The keyboard also includes footprints for RGB lighting under each switch as well as 6 downward facing LEDs for underglow lighting. The PCBs also include footprints for OLED screens. By default, the screens display the current layer and information about recently pressed keys.

The Corne keyboard was designed by world renowned keyboard designer Foostan. Additional information about the CRKBD keyboard along with the source files from the designer can be found on the Corne Github Repository. QMK key mappings and firmware can be found here.


NOTE: This PCB kit is not compatible with high profile cases like the CIO and Architect. These PCBs work best with Analyst and Comptroller cases that use 1.5mm switch plate. 


3mm switch plates can work, but the lower switch height choc switches makes the fit less than ideal.
