Infinity ErgoDox Mechanical Keyboard

Ergonomic Split Keyboard

The Infinity ErgoDox Mechanical Keyboard Kit is a fork of the enormously popular ErgoDox Mechanical Keyboard (Note: This link is a historical archive we have recreated of the original site, as the domain was hijacked by spammers). The ErgoDox was invented by Dominic Beauchamp, known as “Dox”, and is inspired by the Key64 project. The project originated on the keyboard forums Geekhack and Deskthority and has since evolved into a much larger series of projects, independently operated by several different groups. The design seeks to address many of the problems faced by regular keyboard users and is one of the most popular DIY keyboard kits available today. The major issue solved by this design is the problem present in designing a keyboard for people with different shoulder sizes. The Infinity ErgoDox is a split keyboard, so each half can be placed in the position that fits best and is most comfortable for the individual typist.

One of the major innovations added that distinguishes the Infinity version from the rest of its kind is that it comprises two distinct keyboards that are separately usable, while all the other variants are a single keyboard that is physically split. This was accomplished by developing a Keyboard Interconnect that allows for the daisy-chaining of keyboards. The Infinity also is the only version to come with an LCD screen attachment, which was specifically added to allow users to keep track of what layer they are using without having to rely on their computer. Other additions include proper layering and programmability using the Keyboard Layout Language (KLL), as well as LED controllers for aftermarket modification.

The goals for the Infinity ErgoDox were the most complex objectives in any modern keyboard we know of.

1. Open Source Design
2. No Upfront Tooling Costs
3. Fully Programmable Keys
4. Split Keyboard Functionality
5. LED Control Screen
6. Infinite Layers in each Half

Over 1000 people participated in the initial launch of the Infinity ErgoDox on Massdrop. At the time, this was the largest community group buy for a mechanical keyboard design and it continues to be the most popular version of the ErgoDox available on Massdrop. This keyboard is produced in batches and is not available to purchase on-demand. If you would like to buy an one, please join our mailing list to be notified when the group buy window opens up. This practice allows us to keep the price much lower than the other ErgoDox types available as we do not need to maintain any inventory and can produce keyboards based on immediate demand.
