Corne, also known as Heliodox is a split, columnar ergonomic kit-keyboard. It is sometimes referred to by the abbreviation called crkbd. It is an open design and has been used as base for several other kit-keyboards.
It has three rows, six columns (unless one is broken off) and three thumb-keys per hand.
There are four main variations:
- Classic
- Cherry: Cherry MX switches in Kailh hot-swapping sockets.
- Chocolate: For Kailh Choc switches.
- Lightweight: Simple to build
There is a Pro Micro in each half, connected via a TRRS cable that speaks I²C or a faster serial protocol. If I²C is used, it supports also a OLED module in each half.
