Inside the MM710
Once the back feet are removed, you have access to the screws to open the MM710. What we find is that in the top half, it is frame, buttons and an inner assembly locking parts of the mouse together and also the plastic spring mechanism for the DPI button. The lower half to the right holds all the cards and on a PCB roughly half the length of many other mice.
Digging right into the components used in the MM710; first, we see one of the Omron switches, which is indeed a twenty-million click D2FC-F-7N white switches we are all used to using by now. Behind it is the ALPS scroll switch that gives the segmented feel to the scroll functionality.
Backing the pair of buttons on the left side of the MM710 are these pad style switches. They are YT branded switches. These take medium force to be used, but in this design, the sound is a very plastic sounding click when pressed.
The DPI selector button, while we expected less, we are pleased to see a white Kailh switch used here. The pressure needed for actuation is soft, and much like the side buttons, the click is not as pleasing as we have heard in other mice.
From the beginning, Cooler Master was not shy about informing us of the use of a 32-bit ARM Cortex M0+ processor, but unlike with the switches, they did not mention the maker. In ours, we find the Holtek HT32F52352 in charge of communication, functionality, and delivering 512KB of onboard memory. Plenty of grunt for the MM710 and its feature set!
As described, in the middle of the PCB, near the bottom edge, we find the PixArt PMW3389DM optical sensor used. Not only can it scale the DPI from 200 to 16,000 DPI, but it can also track movements of 400 IPS at 50Gs! The regular abuse we put on mice should be no issue for this sensor to keep track of where you are.
The second of the main buttons are also backed with an identical Omron switch as we saw on the left side. Just behind it, we do see the last switch inside of the MM710, which allows for the scroll wheel click function. The green Huano switch requires medium force for use, but the click from it is solid, and what we expected of the other secondary switches.
With the mouse back in one piece, not much has changed from the image we showed at the introduction. We have connected the mouse to the PC, but with a complete lack of LEDs of any sort, visually, there is no indication of life.
