Q4RWC164T1/24 BOBBLE HEAD RC CAR

Operation Description The 1/24 Bobble Head RC Car is powered by 2 X 1.5V ìAAî size battery. There are four buttons in the front of EUT. When the forward, backward, turn left and turn right button is pressed once, it will transmit a radio signal to receiver Refer to the circuit design, the circuit description is listed as below:
 IC101 and associate circuit act as encoder.
 X1 and associate circuit act as oscillator.
 Q101, Q102 and associate circuit act as key board control.
 T2 and associate circuit act as transmitter amplify.
