Cooler Master MasterMouse MM520 Gaming Mouse Review

Inside the MasterMouse MM520




Two screws at the heel of the MM520 allow us to get inside to have a look around. In the top half, we see a weight which is 10 grams and helps to explain the weight increase from the Spawn. The lower half is where all of the magic happens in the MM520.





We do not see any brand marking on the segmented scroll wheel switch, but under the left button is an Omron switch. It is the D2FC-F-7N(20M) variety, it requires medium force to use, and the click coming from the switch is crisp and solid sounding.




The buttons on the left side of the mouse, used to move pages forward and back, are backed by pad switches on pillars. Again, with these switches, there are no names present, just the "14" engraved into the metal frames.




Used to back the DPI selector button, we find a non-descript brown pad switch. More force is required for use than the Omron switches, and while there is a click when pressed, it sounds hollow and not as crisp as others.




The PixArt PMW-3360 is what is in control of tracking all movements, and by itself cannot deliver the DPI offered in the MM520. Cooler Master uses software to bolster the abilities of this sensor, providing 12,000 DPI for those who wish to try to control the mouse at that level.




Boasting 512KB of onboard memory, this Holtek HT32F52352 chip not only does that but is what manages all traffic and allows for customizations. This is a 32-bit ARM Cortex M0 MCU, and it has more than enough grunt to run everything the MM520 brings to the table.




The last image from inside of the mouse is that of the second Omron switch used under the right click button. Used for the click function to the scroll wheel, we find a Kailh brown switch, which is firm, and the click is crisp.




Once powered, the go-to colors on the MasterMouse MM520 is purple. The zones around the back, the logo on the heel, and the scroll wheel near the front can all be addressed via software so that the aesthetics can be changed to suit any environment.
