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.

PCBs utilize Kailh Choc Hotswap Sockets that can only be used with Kailh Low Profile Choc switches. 

This particular Corne PCB variant includes footprints for Kailh Choc Hotswap Sockets and must be used with Kailh Low Profile Choc switches.


Kit - Kits must be assembled in order to be used. The following components are included with each kit.

2 TRRS Jack
2 Reset Switches
42 Surface Mount Diodes
42 Kailh MX Sockets

- These PCBs are assembled by hand and come with all components soldered onto the PCB. The TRRS Jacks, Reset Switches, Surface Mount Diodes, and MX sockets are tested prior to shipping to verify functionality.

In addition to the components included with the kit, the assembled PCBs also come with Mill Max Ultra Low Profile sockets for the Pro Micros (or equivalent) as well as sockets for the OLED screens. This is done to allow for testing to verify functionality after the PCB is assembled.

Pro Micros and OLED screens are not included and will need to be purchased separately. Pro Micros and OLED screens will need to be socketed in order to be used with the assembled PCBs. 

Pro Micros can be purchased here and here. Compatible OLED screens can be found here. An informative guide for socketing Pro Micros can be found here. The same steps can be used for socketing OLED screens.
