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 Matias switches in the 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.

The case measures merely 26×12cm, (10×5 inches) and a fully assembled board weighs about 300 grams, (10½ oz, 400 grams in acrylic) making it easy to take with you. The small size means that your fingers never have far to reach, and it fits easily in your lap where your arms can stay in a comfortable, neutral position.

The detailed assembly guide goes through all the steps to go from a kit to a working keyboard with a few simple supplies. Some soldering experience will help, but even for a beginner most mistakes can be easily corrected. If you're curious what it's like to put a kit together, several people have documented the process.

If you're worried about your soldering ability, presoldered kits allow you to put one together without needing to attach the controller and the diodes. The only soldering you have to do is on the switches, which are much easier.

We also offer a limited number of fully-assembled keyboards for those who would rather not construct their own.

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.
