The XM2w 4K incorporates the optical sensor PixArt PAW3395, which offers a maximum resolution of 26000 CPI and a tracking speed of 650 IPS. The sensor technology supports acceleration of 50G and a minimum Lift-Off Distance (LOD) of 1mm. The MotionSync function synchronizes the sensor signals with the system's polling cycles for stable position reporting. All smoothing and angle-snapping filters are disabled, providing raw data tracking, while in Corded Mode all power-saving settings are completely disabled.
Description
Specifications
The Endgame Gear XM2w 4K is the top wireless implementation of the XM series, designed for competitive use with a weight of just 62g and no external holes. It features the high-end PixArt PAW3395 sensor with a resolution of 26000 CPI and MotionSync technology for absolute precision. Its architecture is based on dual microcontrollers, Nordic and Nuvoton, achieving a polling rate of 4000Hz to minimize latency. Equipped with pre-selected Kailh GX SPDT switches for instant response under 310 microseconds and a hybrid design for the skates made from PTFE.
PixArt PAW3395 Sensor & MotionSync
The XM2w 4K incorporates the optical sensor PixArt PAW3395, which offers a maximum resolution of 26000 CPI and a tracking speed of 650 IPS. The sensor technology supports acceleration of 50G and a minimum Lift-Off Distance (LOD) of 1mm. The MotionSync function synchronizes the sensor signals with the system's polling cycles for stable position reporting. All smoothing and angle-snapping filters are disabled, providing raw data tracking, while in Corded Mode all power-saving settings are completely disabled.
Wireless Technology 4000Hz with Nordic MCU
The management of wireless communication is handled by the Nordic nRF52840 microcontroller in the mouse and the Nordic nRF52820 in the 4K Dongle. A third processor, the Nuvoton M483, serves the high-speed USB connection. This architecture enables a polling rate of up to 4000Hz, reducing data transmission time to 0.25ms. Transmission stability is ensured through a dedicated algorithm, minimizing sensor and click latency to levels lower than wired solutions with 1000Hz.
Kailh GX SPDT Custom-Made Switches
The Kailh GX mechanical switches feature an SPDT (Single Pole Double Throw) configuration for optimal electrical contact, eliminating the double-clicking phenomenon. With an average latency of less than 310 microseconds (measured at 4000Hz), they offer extremely fast actuation. They support GX Speed Mode for speed and GX Safe Mode for signal reliability. The click feel is crisp and tactile, while the switches are pre-sorted to ensure uniformity in actuation force and reset.
Internal Design & Weight 62g
The shell retains the classic shape for claw grip, but has undergone a complete internal redesign to reduce the weight to ~62g. The construction remains solid without external holes (honeycomb), ensuring structural integrity and durability. The weight distribution is balanced for optimal control during fast movements. The surface features a special coating that provides a stable grip even in sweaty conditions, while the materials are resistant to long-term wear.
Hybrid PTFE Skates & Energy Management
The base of the XM2w 4K features a hybrid skate socket design, allowing the installation of either small or large feet made from 100% PTFE. The package includes both sizes, as well as an optional sensor skate for use on soft pads. The firmware focuses on maximum performance without aggressive power saving during use (Almost No Power-Saving). However, the software provides the option to customize the sleep timers and power settings for users who want longer battery life.
