Inside the G502 Proteus Spectrum RGB

Inside of the top, many levers and hinges allow all of the buttons on top to function free from each other and deliver the precision felt in all of the buttons. The lower section is packed with switches and is built with two PCBs on the bottom half.

Under the left click, as well as under the G7 and G8 buttons set to copy and paste by default, are all backed with Omron switches. Also in this design, any wobble, gaps, or lag in the press of each button has been illuminated, delivering precise audible clicks when needed.

Even the smaller secondary switches are made by Omron. The lowest one is used for the "Shift" button, and the two at the top are used for the G4 and G5, which are set by default as page back and page forward. These are slightly softer, and less audible when used.

Switching DPI on-the-fly is no joke it seems, as that button on top of the mouse, the G9 button, is also an Omron switch. This isn't because of just DPI changing; it is because all these buttons are reprogrammable, and it keeps the same feel across the top of the mouse. We also see the MCU has had a sticker applied to it.

Removing the sticker, we indeed find a 32-bit ARM Cortex M3 MCU used in this design. While marketed as a value-line product, there is plenty of grunt in this chip to do everything you and the G502 features demand of it.

Some have said this is the best optical sensor in the game, and it appears that Logitech has exclusivity to the PMW3366 from Pixart. We have seen versions that are close to this, but we do not recall seeing this particular sensor in any mouse, Logitech made, or not.

The rocker motion of the scroll wheel uses black pad switches; they are stiff, and they are audible. We also see that Logitech kept the theme going with the main switches, and employs this last Omron switch for the right click button.

Putting the G502 back together, and then plugging in the cable to our PC, we found that we are greeted with the standard LED color as matching the packaging. It offers a breathing mode, color cycling of the millions of colors, and the DPI lights shown, turn off quickly, and are not adjustable as to their color.
