Inside the Rival
Inside of the Rival we find that the top half houses a PCB that is connected via thin wires, and at the back is a large cut-away to allow the LED to shine through to the logo. On the right is the main PCB and components that we are about to show in detail.
Removing and flipping over the PCB from the top half shows that the CPI button just behind the scroll wheel uses a white TTC switch. It has a medium actuation pressure and makes an audible click when pressed.
As for the pair of side buttons on the left side of the Rival, they are backed with white HC switches. Here there is a heavy actuation force required, and there is also an audible click when it is pressed.
Under the left click button is a white switch, much like those we just looked at, but here they are designed by SteelSeries. These switches are light on the force needed, are near dead silent, and have a thirty million click lifespan.
Taking on the task of both controlling the Rival as well as communications is the 48MHz Freescale MC9S08JM16 MCU. It is a selectable 8-bit or 16-bit processor, and should be plenty to keep the Rival functioning well.
This is also the first time we are seeing this Pixart Imaging PAW33100H optical sensor. You can take it as far as PAW33 before Google stops providing information. We can only go from the packaging, specs, and what the software will show us.
The scroll wheel click function is backed with another white TTC switch with the same feel as the one for the CPI button. The right click button is also backed with the same SteelSeries switch that we found on the other side of the Rival.
After a bit of assembly, the Rival is all back in one piece, and we went ahead and added the power. While you do have full color options for the illumination of the scroll wheel individually from the heel of the mouse, it comes set to SteelSeries orange out of the box.
Spinning the Rival around, the heel of the mouse is also glowing orange now, and the LED lighting is also set to "breathe" mode without any fiddling in the software first.
