Logitech has announced new entries in its popular lines of gaming mice and keyboards. The G603 is a fairly simple wireless mouse that uses Logitech’s proprietary Lightspeed technology, which promises to reduce latency to a millisecond, along with a new optical sensor called Hero that’s designed for power efficiency.

The G603 will come in at $69.99 upon release this month, which is cheaper than the more advanced G703 and G903 mice introduced alongside Lightspeed earlier in the year.

The HERO Sensor

Logitech’s new HERO (High Efficiency Rating Optical) sensor is making its debuting in the G603 mouse. The whole idea behind it is to offer a high efficiency, super-accurate sensor that offers 1:1 tracking with zero smoothing and jitter throughout entire DPI range. Logitech stated that although some mice claim to have sensors that can do this, it’s a little specious. Reps didn’t mention any names, but we believe they were referring to, among others, the SteelSeries Sensei 310 and Rival 310. Logitech said that the HERO sensor offers the true tracking throughout the entire DPI range instead or replying on a touch of smoothing, etc., on certain portions of the DPI range.

Logitech is making some big promises with the HERO sensor, including the claim that it can offer more than 98% accuracy on all surfaces (that are reasonably suited to mice) while achieving max speeds and acceleration rates.

Logitech built the HERO sensor in collaboration with a Swiss partner, and as has been the case in times past, the fruit of that labor is a semi-proprietary sensor. Logitech hasn’t made any hard decisions yet, but it may choose to license the sensor to other companies–or not.

Logitech said that the HERO offers performance on a par with the famed PMW3366 but with 10x the power efficiency. In its materials, Logitech stated that “The entire design has been thoroughly optimized for low power consumption from the lens cluster all the way to how the sensor integrates with the MCU (Micro Control Unit) of the mouse.”

The front end of the HERO sensor is analog, and Logitech boasted of a 30 x 30 pixel array that gathers imaged surface data, but the imaging system is also designed to save energy by shutting down between image captures–in other words, the usage dynamically scales.

The processor can be embedded into the MCU, which saves time and money and gives Logitech some engineering flexibility, according to company representatives. Logitech also claimed that its A/D converter “uses much faster and low power operating circuits (XTRAFAST)” to further enhance efficiency without sacrificing performance.

Perhaps the most important feature of the HERO sensor is the fact that you can fully flash the firmware, which means you can keep updating the device indefinitely as the company develops new features or performance tweaks or optimizations.

In a nutshell, Logitech went for both maximum efficiency and maximum performance.

The G613, meanwhile, is a mechanical keyboard that also uses Lightspeed, and Logitech is claiming that two AA batteries will be good for 18 months of use. The keyboard features six programmable keys, Logitech’s own Romer-G mechanical switches, and will sell for $149.99 this month.

Finally, Logitech has announced the G840 Extra-Large Mouse Pad, which is exactly what it sounds like: a mouse mat that’s almost the size of a table. (It’s the grey rectangle in the photo above, in case you didn’t realize that was actually a product.) Logitech says that all three products together constitute “the next-generation wireless desktop,” but you’ll have to wait a little longer to complete the set; the mouse pad will be available sometime next month for $49.99.
