Iris Rev. 3-5

Build Compatibility

This build guide is exclusively for Rev. 3-5 of the Iris, which features pre-soldered components. For Rev. 2 PCBs, see Iris Rev. 2 Build Guide.

This guide can also be used for the Nyquist Rev. 3, as it has a very similar construction.

Prepare Components

Have your soldering iron, solder and, if you feel accident prone with your soldering (it's ok! Happens to the best of us!), a solder sucker.

Some individuals may want to lubricate their switches. If you'd like to, go ahead and do that now before starting the process. For further details on that, go here.

Optional additions!

These items are optional additions, but if you do want them included in your board, the time to act is now.

Add 2u stabilizers to PCB

Solder rotary encoder

Add buffer for acrylic plates

If you are using acrylic plates, you may want to add something in between the bottom side of the plate and the top of the PCB. This prevents the plate from shifting around, since for a 3mm plate, the switches are unable to clip in.

Add switches

:::note FOR KALIH BOX AND KAILH CHOC SWITCHES - INSTALL LEDS BEFORE THIS STEP For Kailh Box and Kailh Choc switches, there is no cutout to insert in-switch LEDs through, so the LEDs must be added first. Skip to the LED installation step and then come back to this step of switch installation. :::

Optional additions! Part 2

Solder in-switch LEDs


Assembly Option!

If you have an acrylic middle layer with tenting holes, here's a video on how to add bolts to it: Tenting Your Iris with Bolts

If you have a 3D-printed middle layer, see this page on installing it: Iris 3D-printed Middle Layer Installation

Re-Program Board Note

Oh, looking to re-program your board? Never fear! Come look here.
