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!
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.
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.
- 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

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.
The Iris uses QMK for its firmware, and the code for it is here: QMK - Iris directory.
Everything went together so smoothly for a first time kb builder! The durock sunflower switches and GK happy planet keycaps weren’t the best choices, don’t let the backlights shine, but otherwise I’m loving it.
Using gateron clears with 20g springs and dvorak layout just to make the whole keyboard even nerdier than it was. I've got a blistering 18wpm on this baby! But it's been so much fun, and the keyboard itself is gorgeous. You can also put different layouts on the right and left pcbs, for quickly switching between two.
This PCB is amazing. It’s all the greatness of the rev7, but without the stress of “is there enough room for this compiled layout?” Would totally recommend both the product and the company.
I'm enjoying my keyboard. It's my first split keyboard.
