Iris PCBs with on-board controller and USB-C port. Just solder in your switches and you're done!
9/27/2019: The limited restock (was only a dozen sets) of Rev. 3 sold out, sign up to be notified about the Rev. 4 release on other product page.
Item Contents
- Left half PCB
- Right half PCB
Features
- On-board ATmega32u4 controller
- USB-C port
- 6 RGB underglow LEDs per half (12 total)
- In-switch LED support
- Option for rotary encoder at lower left corner of left half
- Pre-flashed with QMK Firmware and VIA configurator 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.

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.
