How the wireless mouse works
< br >
Workflow: LED (light) - desktop - optical lens - Optical SENSOR - master chip (MCU) - RF IC - antenna transmit - antenna receive - RF IC - USB master chip - USB cable - PC screen coordinates

When the mouse moves, the optical sensor continuously collects every point on the desktop, sends the collected point to the master chip for memory and compares the bit difference of the next point. The master chip converts the displacement signal compared into the corresponding interface information through RF IC to make wireless carrier signal and transmit it through the wire, and the receiver receives the corresponding wireless carrier signal through the antenna. After RF IC modulation detection of the corresponding interface information to the USB master chip, the master chip is converted into USB signal, and then transmitted to the computer through the USB cable, so as to achieve the cursor up and down movement.
The construction of the principle of wireless mouse:
Using DRF technology, the mouse movement on the X or Y axis, key press or lift information is converted into wireless signals and sent to the host.
