Inside the 450M
Opening up the 450M shows us that the top half offers no additional weighting added to weigh it down. The lower section offers a single PCB that offers eight switches and two large LEDs, one just behind the scroll wheel, and the other under the Cougar logo in the heel.
The left click button is backed with an Omron D2FC-F-7N switch that gives you five million clicks, and the scroll of the wheel is handled by a TTC switch.
The red switches used for the side buttons of the 450M are unfamiliar to us with a script style IB marked on the top of them. They require a fair amount of force to activate, and also report with a solid click when pressed.
The sensor we found in control of tracking all of the movement is indeed the PMW3310DH Pixart optical sensor. With the specifications of this sensor, you will have a challenging time trying to get this sensor not to be able to read anything you do with this mouse.
The 450M also comes with a 32-bit ARM MCU. In this instance, Cougar has chosen the NXP LPC11U14F to take care of communications with the sensors and switches and to send it through to the PC. This is also where the onboard memory is located so that you can program the mouse and not need the software or the home PC to keep the setting you prefer to use.
The right side of the 450M offers two more of the red switches for the side buttons, and a pad style switch for the click function of the scroll wheel. As to the one under the right click button, it too is an Omron switch that matches the one found on the other side.
At this point, we put the 450M back together and powered it up. At this time, the default color for the logo and the scroll wheel LED is green to match the color of the outside, but these two can be changed to anything you can desire. As for the DPI button, it is currently green as well, but as you move up in DPI, it changes to blue, and then to yellow for the highest DPI level.
