We are pleased to announce a collaboration with our friends at Keyboardio: the Keyboardio Atreus!


The Atreus's mechanical switches enjoy great popularity among keyboard enthusiasts for their precise, crisp action. Most keyboards use a layer of cheap rubber to provide resistance under the keys, but each of the key switches in the classic Atreus has its own separate spring.

Many other ergonomic keyboards offer a split design where each hand can be naturally positioned at a different angle, but most of them use the typewriter-era staggering where each row is shifted over a bit to allow the typewriter's striking arm to come up. Instead of doing this, the Atreus arranges keys with a vertical stagger to reflect the fact that the fingers of the human hand are of different lengths. It also places more keys within the reach of the thumbs.

Any questions that aren't answered here? Try the FAQ or posting on the mailing list.

Because there are so few keys, typing relies on the fn key, which changes to a layer containing a numpad, arrows, and punctuation when held. A final layer contains function keys and other less-common keys, but the firmware is hackable and can be modified to do nearly anything.

Note that the Keyboardio Atreus has two extra keys and a slightly different layout.


Layers: letters | punctuation/digits | arrows/function

See the Keyboardio shop to get your hands on one of the new Atreus keyboards.

This site is kept up primarily as a resource for people who have bought the classic Atreus kit in the past. From time to time, a very limited number of wooden classic Atreus builds are available at a significantly higher price than the Keyboardio Atreus.
