ATK U2 V2 Ultimate

45g Lightweight Design

The defining characteristic of the ATK U2 V2 Ultimate is its low weight. At only 45g ± 3g, the mouse is designed to minimize resistance during fast and repeated movements.

Its symmetrical body measures 123.7 × 64.6 × 39.1mm, with a rear-positioned hump that provides additional palm support while maintaining the agility required for claw-style control. The shape is particularly suited to medium and large hands, with claw grip being the recommended grip style.

The lightweight construction is especially beneficial for FPS gaming, where rapid flicks, tracking, and large mouse movements are common.

PixArt PAW3950 Ultra Sensor

At the heart of the U2 V2 Ultimate is the PixArt PAW3950 Ultra, a flagship-class optical sensor designed for precise and consistent tracking.

The sensor supports up to 42,000 DPI, 750 IPS tracking speed, and 50G acceleration. This provides a high level of tracking performance for competitive gaming, allowing the mouse to accurately follow both subtle adjustments and rapid movements.

For players who use low sensitivity, the combination of a lightweight body and accurate sensor makes the U2 V2 Ultimate particularly well suited to fast FPS gameplay.

Dual 8K Polling — Wired & Wireless

The U2 V2 Ultimate supports up to 8000Hz polling in both wired and wireless modes when used with the appropriate 8K receiver.

A higher polling rate allows the mouse to send position updates to the computer more frequently, helping provide smoother cursor movement and lower input-reporting intervals. ATK’s implementation also supports 8T8R bidirectional 8KHz transmission, with a claimed response latency of approximately 0.181ms.

The polling rate can be adjusted through ATK’s software according to your system and gaming requirements.

Nordic 54L15 MCU

The U2 V2 Ultimate uses the Nordic 54L15 MCU, paired with ATK’s self-developed 54 Series ApexShark MAX Mouse Solution.

This hardware platform is designed to support the mouse’s high polling rate, wireless communication, sensor processing, and overall responsiveness.

ATK Custom Optical Switches

The main buttons use ATK Custom Optical Switches, providing fast actuation and consistent click performance.

Optical switches use light-based detection rather than traditional mechanical electrical contacts, helping reduce issues associated with physical contact degradation. The U2 V2 Ultimate is designed around this technology for reliable performance during extended gaming sessions.

TTC Gold Scroll Wheel

The mouse is equipped with a TTC Gold scroll wheel, providing controlled scrolling and tactile feedback while maintaining the lightweight design of the mouse.

500mAh Battery & Extended Runtime

Despite its 45g weight, the U2 V2 Ultimate incorporates a 500mAh high-density battery.

ATK rates the mouse for 500+ hours of battery life at 1000Hz, although actual runtime can vary depending on polling rate, lighting, wireless settings, and usage. This makes the U2 V2 Ultimate suitable for users who prefer extended wireless operation without frequent charging.

New Nano Coating

The exterior uses ATK’s new nano coating, designed to provide a refined surface while helping resist dirt and fingerprints. This gives the mouse a cleaner feel during extended use and complements its minimalist design.

Wireless & Wired Connectivity

The ATK U2 V2 Ultimate supports 2.4GHz wireless and USB-C wired connectivity, with the new-generation 8K receiver providing the high polling rates required for competitive gaming.

Wireless mode keeps your setup free from cable drag, while wired mode provides a direct connection and allows you to continue using the mouse while charging.

Designed for Competitive FPS Gaming

The combination of a 45g body, PAW3950 Ultra sensor, 8K wireless polling, optical switches, and a symmetrical claw-oriented shape makes the U2 V2 Ultimate particularly well suited to competitive FPS gaming.

The lightweight body allows rapid movement, while the high-end sensor and high polling rate provide the tracking performance needed for precise aiming and fast reactions.

At the same time, its symmetrical shape makes it a versatile option for users who prefer claw-style control rather than a traditional ergonomic mouse.

Why Choose the ATK U2 V2 Ultimate?

The ATK U2 V2 Ultimate wireless gaming mouse brings together some of the latest gaming mouse hardware in an exceptionally lightweight package. Its 45g weight, PAW3950 Ultra sensor, Nordic 54L15 MCU, dual 8K polling, ATK optical switches, TTC Gold wheel, and 500mAh battery make it a serious option for competitive gamers looking for high-end performance without a heavy chassis.

For gamers in Bangladesh searching for a lightweight wireless gaming mouse, ATK U2 V2 Ultimate, or a PAW3950 gaming mouse, the U2 V2 Ultimate offers a strong combination of precision, responsiveness, battery life, and build quality.
