## What it is
The Corne (Crkbd) keyboard is an open-source split ergonomic keyboard design with 3x6 column-staggered keys and 3 thumb keys, based on the Helix keyboard. The repository contains PCB design files, firmware configuration, and build guides for Cherry MX and Kailh Choc switch variants.

## Use cases
- build a split ergonomic mechanical keyboard
- find open-source keyboard PCB design files
- learn to solder a DIY keyboard from a build guide
- choose between Cherry MX and Kailh Choc low-profile switches
- customize a column-staggered split keyboard layout

## When to choose
- you want a well-documented, popular open-source split keyboard you can build yourself
- you prefer column-staggered ergonomics with thumb keys
- you want hotswappable or soldered build options

## When to avoid
- you want a ready-made keyboard rather than a DIY build
- you need a flat row-staggered or unibody keyboard
- you cannot source components or solder/handle assembly yourself

## Facets
- artifact type: application
- maturity: active
- function: developer-tools
- domain: hardware, cross-platform
- platform: cross-platform
