From the project

A wireless low-profile split mechanical keyboard with 66 keys inspired by the ErgoDash and Corne Chocolate

A wireless low-profile split mechanical keyboard with 66 keys inspired by the ErgoDash and Corne Chocolate. It runs ZMK on two nice!nanos, is fully wireless via Bluetooth and uses Kailh Choc V1 switches in a 18x19mm grid layout.

I used an ErgoDash with MX switches for over a year multiple hours each day. Even though I love typing on it, it always felt too bulky and the wires really started to annoy me - especially when moving between workplaces. At some point I discovered ZMK and started plans on building a keyboard based on the ErgoDash, but as low-profile as I could manage.
