3. Based on former common remote control toy car solution, we have updated
it to 2.4G wireless remote control solution.
The benefits are as follows :
1. low cost and easy operation;
2. 2.4G ISM frequency;
3. reach long distance;
4. simple circuit ;
5. Strong anti-interference ability;
6. Flexible, which it can support at most 25
cars operating at the same time.
2.4G Wireless RC Solution
4. It is controlled by 2.4G and it could Forward, backward, turn left, turn right,
accelerate and brake
1. It uses low-cost 8 bit MCU and high-precision 12 bit MCU ？
2. Few external components, simple debugging, it could be made into module
or directly used on PCB ？
3. Remote distance, which could reach 60 to 100 meters ？
4. Special 2.4G wireless hopping protocol , which could reduce the rate of
losing code to a large extent ？
5. Unique automatic code matching technology, which is so convenient that
can reduce the time before working. Also it allows multiple cars to operate at
the same time.

5. Remote Control
A: Power on, then it will enter into working mode (if the receiver is on, it will pair the codes
quickly);
B: While the sender comes back to the middle position , the system will make the receiver in
idle state. Two handles will control the receiver to go forward or backward. The turn-knob
button will control the car if it is turn left or right.
C: Low -Voltage Notice: according to customer’s requirements, when the voltage is lower
than normal working voltage ( user can set the figure here), the system enter into low voltage
notice mode.
D: Power-Saving Mode: when the sender is in medium
state(the motor is not working), and the buttons are in
idle state for 10 minutes, the system will
enter into power-saving mode
E: LED Lights？ in working mode, the led lights are on
always. This function could be customized
6. A: Within the range of remote control, the car could go forward and backward,
go left and right.
B: Low -Voltage Notice: according to customer’s requirements, when the voltage
is lower than normal working voltage ( user can set the figure here), the system
enter into low voltage notice mode.
C: Power-Saving Mode: when the sender is in medium state(the motor is not
working), and the buttons are in idle state for 10 minutes, the system will enter
into power-saving mode
D: Locked-Rotor Current Test？ it can set the
locked-rotor current according to customer’s
requirements？ For toy airplane with large
current, this function could be added. It is not
available for normal toy car？
