The keyboard has the same small vertical staggering as the ErgoDox but with only six columns and four rows. There can be three or four thumb keys per side, where only the innermost corresponds to an ErgoDox thumb key: That key can also be 1×2 or split into two 1×1 keys.
The first two (major) revisions had a Pro Micro controller board mounted underneath each PCB, and all components had to be through-hole soldered. Underglow is supported through a separate RGB LED strip.
Revision 3 comes with all components (except switches) already surface-mounted, and supports also a rotary encoder replacing the bottom/outer key.
The keyboard is named after the goddess Iris in Greek mythology—the goddess of rainbow and messenger of the gods. It was chosen because the keyboard's curvature was reminiscent of a rainbow, and a keyboard is used to type messages.
The Iris keyboard won the 2017 Deskthority Award in the Best "other" input device category.
