10/19/2017 Status: Order has been placed to restock the black and white PCBs, they should arrive in about 2 weeks.

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!

Item Notes

The PCB Kit includes the following:

  • 2 Iris PCBs
  • 2 Push buttons for reset
  • 2 4.7kΩ resistors for I2C to install on the master half
  • 2 TRRS jacks (no need to buy separately)
  • 56 1N4148 diodes (if you want SMD diodes, please request this in your order notes)
  • LED support components - MOSFET, 100Ω and 100kΩ resistors

The limited edition white PCB features gold-plated pads, for that awesome white & gold look. A regular white PCB will also be available.


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.

There's also a spot on the PCB for a pushbutton switch to reset the Pro Micro for flashing. No more taking a wire/tweezers/screwdriver to jump the Reset and GND pins!

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

The Name

Named after Iris, the goddess of the rainbow and messenger of the gods. The curvature of the top row is something like a rainbow, and keyboards are used to send messages. 


The Iris uses QMK for its firmware, and the code for it is still a work in progress and has not been merged into the main repository yet. You can temporarily find the code here: QMK - Iris directory.


Case parts are available here: Iris Plates/Cases

Here's the case files can be found here: Iris Case Files

    The kerf setting was set to 0.15mm for use with Lasergist and Ponoko.

    Items needed for build

    The build guide is nearly identical to that of the Nyquist except for the added LED hardware, so you can use this guide for now. An Iris specific build guide is in development.
