Kit Type Rev. 5 PCBs

The Iris keyboard, a split ergonomic keyboard with 4x6 vertically staggered keys and 3 or 4 thumb keys. Time to stop stretching your thumbs out on the Ergodox!

Don't want to solder it yourself? Check out our pre-built option here and our hotswap Rev. 8 PCB here!


Each half of the board is a 4x6 matrix with the same vertical stagger as the Ergodox and with 3-4 thumb keys. The 2u thumb key can be replaced with 2 1u keys. The spot for the 2u has holes for Cherry PCB mounted stabilizers. Alternatively, a rotary encoder can be placed at the upper thumb key of each half.

Many thanks to Lewis Ridden (/u/GAMING_FACE) for coming up with this design.

Build guide can be found here: Iris Build Guide

This keyboard uses the popular open-source QMK Firmware with VIA enabled out of the box to allow you to remap all the keys just the way you want them.

Plug your keyboard in, open up the VIA app, and easily change what each key does to get the most out of your keyboard with your customizations! More info on what you can do here: VIA Usage Guide

Default Keymapping

The default keymapping that the board is pre-programmed with can be found here: Default Keymaps

Case Compatibility

Due to the replacement of TRRS with USB-C, a different set of plates and case parts are needed, so older parts (Legacy Edition) can not be used. The newer plates/cases (Phoenix Edition) will be compatible with future revisions.
