Item Contents

• In-switch LED support

Layout

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.

Build Guide

Firmware

The Iris uses QMK for its firmware, and the code for it is here: QMK - Iris directory.

Case

Current Iris Rev. 2 cases will be compatible with the Rev. 3 PCB, but the bottom plate needs an additional hole drilled in it for easy access to the reset button.
