Wireless mouse IC Optical sensor FH8811 and receiver no need transmitting module

1. chip description

FH8811 is a highly integrated chip designed for 2.4G wireless mouse. It innovatively realizes the radio frequency module of 2.4G wireless mouse.

Three-in-one modules of main controller and optical sensor

Radio Frequency Module of Wireless Mouse,

The main controller module and the optical sensor module are integrated into one chip technology. With very few peripheral components, 2.4G wireless can be realized.

Mouse has excellent anti-interference, high sensitivity, very low power consumption and other performance, and can maximize support for simplified production.
