Logitech G903 Hero Repair

The G903 HERO wireless gaming mouse is a revised version of the original G903, featuring Logitech’s more power-efficient HERO sensor. Initially capped at 16K DPI, the sensor was later upgraded to 25K DPI through a firmware update. This updated sensor offers improved tracking, a higher DPI ceiling, and significantly better power efficiency, resulting in much longer battery life compared to the original G903. Aside from the internal hardware upgrade, both versions share the same physical design and are compatible with Powerplay.

The Logitech G903 HERO has a sharp, angular design with a matte black finish and glossy accents along the edges. The overall shape is symmetrical, with cutouts along both sides that frame the removable side buttons. An illuminated blue Logitech G logo is centered on the palm rest, and behind the scroll wheel area are 3 thin RGB light strips.

The G903 Hero can also be identified by its part number, (P/N) 910-005670.
