The Traveller is a variant on the atreus keyboard. Like the Atreus, it is designed to be a good compromise between size and ergonomics.
Key differences are:
You can make your own Traveller keyboard by using the openscad tools from the atreus repository, and adding a hole for the LED to shine through.
Make example for this keyboard (after setting up your build environment):
make handwired/traveller:default
Flashing example for this keyboard:
make handwired/traveller:default:flash
