Logitech G403 Prodigy Wireless/Wired Gaming Mouse Review

Inside the G403 Prodigy




Four screws found under the feet allowed us to get inside of the G403. Once carefully split into its two main sections, we see quite a bit is packed into the top half, with just the main PCB and the battery found in the lower section.





To keep actuation points short with the G403, Logitech puts the main switches right under the large buttons on top of the mouse. We can also see that not only are these Omron switches, but they are the D2FC-F-7N(20M), or twenty million click versions of them.




For the two buttons found on the left side of the G403, even these are Omron switches. While they are not the 20 million click variants of the switch, the feel is identical and will last quite a long time, as they tend to be used less often than the main switches.




With no main switches to block the view of the scroll wheel, we find this is a good time to address the fat rounded scroll wheel, and the use of a Kailh switch to track its movements. The wheel is highly segmented in its movement, and with its increased size, it is easy to use, and is made with a center strip that is LED backlit.




Logitech has chosen to use this Springpower Technology Li-polymer battery to deliver power in wireless mode. It offers 750 milliamp hours at 3.7V, and it rests in a cover to protect it as well as keeping it in place, so its weight does not shift around inside.




The optical sensor used is specific to Logitech as far as we are aware, and is the Pixart PMW3360DM. Via software algorithms, this sensor, can go as low as 200 DPI on the low-end and tops out at 12,000 DPI to keep up with the Jones'. Not like we need 12,000 DPI.



We did have to peel a sticker off the top of the MCU, but under it, we find the ARM STM32L100. This is a 32-bit processor, with 16-bit, in and out communication capabilities. This is a Cortex M3 processor, but more importantly, it is designed for low power applications, lending well to a wireless design.




The last image of the G403 Prodigy is with it displaying its color in Logitech blue. The G logo on the heel is brightly illuminated, and at the right angle, so is the center strip of the scroll wheel. By default, the color is constantly changing inside of the mouse, as it cycles through the full RGB scale.


Also, both the scroll wheel LED and the one under the G logo, both illuminate the same color unless in charging mode with the mouse turned off. It is then that the scroll wheel will flash a green LED, and the log is turned off.
