                       Operation Description
The transmitter use a SOC(system on a chip)chip MA3201, most of function can be
finished by one chip, such as key-press detective, and it is the part of RF operating
circuit. The transmitter is made of U1(MA2301), SENSOR U3 PAW3204,U2 is ID
code storage IC, U5 is power management IC. U5 is the circuit of boost pressure, it
make the battery’s voltage reach 3V to support the mouse working. Clock oscillator is
made of U1 internal circuit and X1, X2 surrounding circuit, and it can supply the
power for clock pulse. Once start the SWR,SWL,SWM,SWZ switch, U1 will be
process. U3 is optical chip, it can react the movement of tabletop then deliver to U1,
U1 will finish all the data code internal and modulate, then enlarged by internal
circuit,at last it delivered to the air by antenna. U2 is ID code memory, after the
mouse and receiver code connect together successfully, U2 will record this code and
backup it for next time.


Antenna is formed by a copper trace on the PCB. Common grounding on PCB is not
connected to real external ground. Power supply is DC 3V by two “AAA” batteries.
