Inside the SP80
The single screw seen from under the mouse is all that holds the SP80 together, and once removed we can see the guts. There is a PCB that stays with the top half, and you will need to be gentle as not to damage the cable. The lower section contains the rest of the components, and even an additional weight screwed into the heel of the mouse.
The trio of buttons behind the scroll wheel are backed with red Huano switches. These are softer switches to actuate, and the report is a crisp click, but not that loud. The pad switches on the right back the side buttons on the mouse. These are soft to actuate, and the report is more of a thud than a click.
The scroll wheel spins on an optical LK switch, and the switch under the left main button is also a Light Strike optical switch. We already mention the heavily segmented movement of the scroll wheel, but the main button has a similar feel to an Omron switch with a crisp clicking noise.
The PixArt PMW3360 is the optical sensor of choice, and while the box claims 1:1 raw performance, we feel differently. We have played with other mice sporting this sensor, and if we had to guess, movement is like two or three to one. We feel that this sensor and the way Bloody tuned it is vastly more sensitive to movement than others using it.
While the white painted line does make it tough to see, we believe this to be the Sonix SN8P2213 MCU. If our reading through paint skills are on point, that means this is an 8-bit controller, which may seem like it is not enough grunt, but with what we know in testing, it has the ability to cover all of the features as well as the communications of what the SP80 can do moving it or pressing buttons.
Now at the right side of the mouse, back to the front, we see the other fifty million click LK switch used under the right button. As for the Huano behind it for the scroll wheel click, is indeed, the strongest switch in the SP80.
All back together and powered, we see that the SP80 delivers LED lighting through the scroll wheel and behind the logo. We do see lighting through the cracks of the side s, but the back is barely lit.
