Iris Rev. 8 Keyboard - Hotswap PCBs for Split Ergonomic Keyboard
$79.99The 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.

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.
