A wireless gaming mouse sold under the traLight brand is equipped with a PixArt PAW 3955 optical sensor and a Nordic 54LM20A microcontroller that enables a polling rate of up to 8,000 Hz, according to the product's specifications.
The PAW 3955 is PixArt's high-end optical gaming sensor, and the Nordic 54LM20A serves as the mouse's main microcontroller. Nordic Semiconductor's 54LM20A belongs to its nRF54 line of low-power wireless MCUs, which handle the device's wireless communication as well as the high polling rate of 8 kHz — meaning the mouse reports its position to the host PC 8,000 times per second.
The combination of a PixArt sensor with a Nordic wireless MCU is a configuration commonly adopted in performance-oriented wireless gaming mice, where sensor accuracy and low-latency, power-efficient wireless connectivity are the key differentiators.
An 8 kHz polling rate reduces input latency between the mouse and the PC relative to the 1 kHz standard that prevailed for years, a feature aimed primarily at competitive gamers. The PAW 3955 sensor handles tracking performance, while the Nordic MCU's low-power design supports wireless operation without the battery penalties that high polling rates would otherwise impose.
The claim regarding the two components and the 8 kHz polling figure matches the product's listed specifications.
Verdict: True
