With the release of more recent models like the Iris CE and the Iris LM, things can get a bit confusing on what case parts are compatible with what, so here's a rundown of it.
Iris Models
Original line of Iris keyboards
The "original line of Iris keyboards" here refers to the currently available Iris keyboard parts that support the commonly used MX-style switches, so Iris Rev. 5-8 PCBs and the Iris PE case parts, Iris Aluminum Case (to be renamed as Iris AE), Iris Essential Models, and the Iris SE. The spacing of the keys (keyspacing) is at a standard 19.05mm between the centers of the keys, both vertically and horizontally.
Iris CE (Compact Edition)
Iris CE is short for "Iris Compact Edition", which is only compatible with Kailh Choc V1 switches. Additionally, the keyspacing is closer than the original Iris, with keys spaced 17mm apart (center-to-center) vertically and 18mm apart horizontally.
Iris LM (Low-profile, MX-spacing)
Iris LM case is compatible with two different PCBs, the Iris LM-K and the Iris LM-G. The keyspacing is 19.05mm vertically and horizontally like the original line of Iris keyboards. The cases are designed to be low-profile similar to the Iris CE.
The Iris LM-K PCB is compatible with Choc V1 low-profile switches and Choc V2 low-profile switches.
The Iris LM-G PCB is compatible with Gateron KS-33 and KS-27 low-profile switches.
PCBs
These are the main PCBs for the Iris that will be available:
- Iris Rev. 5 PCBs - Solder version of the original line of Iris keyboards (MX/Alps/Choc switches)
- Iris Rev. 8 PCBs - Hotswap version of the original line of Iris keyboards (MX switches only)
- Iris CE Rev. 1 PCBs - For Iris CE keyboard (Compact Edition) (Choc switches only)
- Iris LM-K Rev. 1 PCBs - For Iris LM keyboard (using Choc V1 and Choc V2 switches)
- Iris LM-G Rev. 1 PCBs - For Iris LM keyboard (using Gateron KS-33 switches)
Cases
There are various case parts for the different Iris models as well:
- For the original line of Iris keyboards, these cases are compatible:
- Iris PE - Note: Pre-built keyboards and Iris Essential Models are built using these parts. These parts will also be phased out in favor of Iris SE parts.
- Iris Aluminum Case (Iris AE)
- Iris SE Aluminum Case
- Iris SE Polycarbonate Case (in development)
- For Iris CE:
- For Iris LM:
- Iris LM Aluminum Case
- Iris LM Polycarbonate Case (in development)
