Circuit ‘s operation Description for DS-2075 This circuit is mainly consisted of convertor IC（U4）， IC（U3）,MCU IC（U2）. IC U4 provides the circuit with a stable 3Vvolts d.c and U3 provide the circuit with a stanble 4 V . to keep the circuit working.。when the mouse is moving on the desktop, photoelectric processor IC-U1collect optical signals reflected by the desktop，and transfer them into the MCU IC-U2 ， then processed and managed. By MCU ， together, they are sent to the FSK circuit 。 In the MCU IC-U2,there is internal RF Generator，the electric signals out from MCU will be generated, and output the data from 8# feet of U2 ， and radiate the signal to outside 。 MCU will provide and generate a code from the 22# feet of IC-U2 when you press the ID button，at the same time ,MCU will storage this code, and keeping the ID code unchanged until out of power 。 The MCU IC-U2 have two functions of sleep and wake up. For saving up the capacity of power, the circuit will keep sleeping model when the mouse has stopped on the desktop for a fixture time; you can press any key or wheel switch to let it work again.
