The high-speed tri-mode gaming mouse supports USB, 2.4G, and BLE modes to meet different usage needs. In high-speed USB and 2.4G modes, the mouse achieves an 8K polling rate, providing users with a smooth and ultra-low latency experience. Meanwhile, in BLE mode, the mouse is compatible with mainstream Bluetooth host devices on the market (such as computers), allowing for wide application.
System Structure
The Realtek RTL87x2G integrates USB 2.0 High-Speed and 2.4GHz wireless interfaces within a single-chip architecture, delivering a smooth 8K user experience with ultra-low latency. Additionally, its rich peripheral interfaces such as SPI, QDecoder, Keyscan, I2C, GPIO, and PWM enable developers to add advanced features for product differentiation while maintaining excellent power performance. The chip, combined with the mature and comprehensive Realtek SDK, development documentation, and related tools, allows developers to quickly realize their creative ideas.
