Inside the T120P
One screw is all it takes to hold this mouse together, well that and the tabs at the front of the mouse that really do most of the holding together of these halves. We don't recommend opening this mouse as the two wired connections are very short and hard to extract, and the gold ribbon cable is no treat to work with either.
Under the left click button, as well as under the right click button, we find that Rapoo has used Kailh switches, and uses a pad style switch for the click function of the touch pad section of the T120P.
Just behind the switches is the Avago ADNS A3000 optical sensor. This takes care of all the tracking that this mouse is capable of within its 1000 DPI of range.
At the other end of the PCB is the 4-bit MCP from Texas Instruments in this TSC 30601 chip. This is what translates the signals for the Avago optical sensor, and sends those signals to the Nano receiver for the PC to equate to movement on the screen.
Now that we have this red T120P all back together, it is about that time to plug in the receiver, turn the switch on, and see what this mouse is capable of.
