Inside the ROCCAT LUA
Once I removed the feet and pulled four screws I was able to remove the top of the LUA without any issue. The upper shell is a two piece design that uses the black plastic on the inside and the soft-touch coated plastic is clipped to it. ROCCAT also left a hole at the back for the LED lighting.
With the top out of the way you can see the majority of the components used in the LUA. The Avago sensor has a layer of foam on it, and I think it is due to the low height of the mouse, and this should absorb any contact the top half could make with the sensor.
The left click and right click buttons both use the Omron switches seen here. I took the image from this angle to allow you to see the specific version used.
For the scroll wheel click and the DPI selector button, less expensive TTC switches are used for those.
Removing the foam you can now see the Avago ADNS A3050 Pro 2 optical sensor used on the LUA. You can now also see the 16-bit chip above it that will be communicating with the PC during use.
To give the logo the pop ROCCAT was looking for, this large LED will glow with arctic blue light to give the ROCCAT logo on to plenty of light to make it clearly visible when powered.
With the LUA reassembled and now plugged in, you can see that the logo surely is bright and blue just as described.
