Iris Rev. 8 Keyboard - Hotswap PCBs for Split Ergonomic Keyboard


The 8th revision of the popular Iris keyboard, a split ergonomic keyboard with 4x6 vertically staggered keys and up to 4 thumb keys. Reprogrammable to any keymap layout you'd like with QMK/VIA!

What's New!

While the layout options for the Rev. 8 is identical to the Rev. 7, the microcontroller has been upgraded to the RP2040, providing a more powerful processor and much more memory to work with.

    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.

        Rev. 8 Features

        • On-board RP2040 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


          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.
