IRIS Rev.7 PCB & Plate

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

Differences with Rev. 7

The differences between this Rev. 7 PCB and the Rev. 6 PCB are the following:

• 2u thumb support has been re-added in Rev. 7
• Additional encoder option has been added to outer top corners
• I2C breakout pads added to each half

Item Notes

Iris PCBs with on-board controller and USB-C port. Just put in your switches and you're done! The rotary encoder pins are not hotswapped, so encoders need to be soldered in if installing them.

Item Contents

• Left half PCB
• Right half PCB

Items Needed for Build

• Iris PCBs (this item)
• Iris Plate Kit
• USB-C to USB-C Cable to connect both halves together
• Iris middle layer (optional)
• 54-56 Switches (MX only)
• USB-C Cable to connect to computer
• Rotary Encoder and knobs (optional)
• Silicone Hotswap Bumpers (optional, but recommended)
• SKUF Keyboard Feet (optional)
• 3D-printed case to supplement plates (optional)

Rev. 7 Features

• On-board ATmega32u4 controller
• Switch support: MX-compatible only
• USB-C port
• MX Hotswap sockets pre-installed
• 6 RGB underglow LEDs per half (12 total)
• Per-key RGB LEDs
• Option for rotary encoders at upper thumb key and outer top corners on each half
• Pre-flashed with QMK Firmware and VIA configurator support
• With VIA configurator, you can reprogram the board without needing to know how to setup QMK and/or QMK Toolbox
• Demo video of VIA

Layout

Each half of the board is a 4x6 matrix with the same vertical stagger as the Ergodox and with 2-4 thumb keys. 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.
