5A dual motor drive

 

5A dual motor drive module  Remote control  Forward and reverse PWM speed regulation  Double H bridge over L298N

 

5A dual motor drive (with remote control, with 3.3V/100ma output)

note! ! ! When the motor is commutating, it must wait for the motor to stop first. Otherwise, the instantaneous current will burn out the module, and the product that burns the chip will not be given after-sales service. The exposed pins on the back of the board must not be shorted, otherwise permanent damage may result. Do not reverse the positive and negative terminals of the power input. There is a printing prompt on the back of the circuit board, otherwise it will burn out.

 

1. Highlights:

1.1. Two motors can be independently controlled, each channel can output 5A, peak 9A, standby current is only 10uA;

1.2. Wide power supply range of 3-14V, signal supply range of 2.2-6V, 3.3V and 5V levels can be satisfied;

1.3. The board provides 3.3V 100ma power supply to meet the power consumption of your control system, and can also be used with 433M wireless module remote control motor, or remote control other loads;

2. Regular control method

3. Remote control mode:

 

The default mode for remote control shipment is jog mode. If you need to change the mode or multiple remotes control one receiver at the same time or one remote control multiple receivers, please do the following:

Clear code -

 

Press the learning button on the receiver 8 times in succession, the LED goes out, the LED flashes 8 times, and the clearing is completed. (If you need to change the working mode of the same remote control, please clear the code before learning)

 

Learning the code -

first step:

Press the learning button on the receiving board according to the number of times you need to select the working mode, and then the LED of the receiving board is always on.

Jog mode: Press the decoding module to learn the button once.

 

Self-locking mode: Press the decoding module to learn the button twice.

 

Interlock mode: Press the decoding module to learn the button 3 times.

 

Step 2: Press any button on the remote control. After the receiver receives the signal, the LED of the receiver board flashes three times and then turns off. The code is successful. (If you enter the learning pair code mode, there is no remote control signal, after 10 seconds, the learning pair code mode is automatically exited.)

Note: If you have selected a mode after clearing the code, then the first step to select other modes is invalid, you must clear the code and then learn! ! !

If you want to control multiple receivers at the same time, enter the learning mode, press the learning button LED, then press any button on the remote control.

6. Module supply voltage 3V-14V;
7. The signal input voltage is 2.2-6V, supporting 3.3V and TTL level;
8. Single working current is 5A, peak current can reach 9A, low standby current (less than 10uA);
9. Mounting hole diameter: 2 mm.
10. Weight: 14g

 

433MHZ remote control transceiver module

433MHz wireless remote control switch with remote control transmitter and receiver remote control motor with antenna

 

Features

1. The remote control adopts the learning EV1527 encoding method, and each remote controller has an independent address code to prevent serial codes and interfere with each other.
2. The receiving module has three function options: jog, self-lock, and interlock.
3. The receiving module adopts the button selection mode. There is no need to manually select the mode by welding, jumper, etc., saving time and labor costs.
4. The receiving module includes a decoding chip to support encoding chips such as EV1527 and PT2262.

Product parameters

1. Working voltage: DC2.5V-5V
2. Working current: 3mA
3. Sensitivity: -108DBM
4. Rate: MAX 10 KB/S
5. Working mode: jog, self-locking, interlocking
6. Module output: 4 CMOS level signals, which can correspond to 4 buttons of remote control "ABCD"
7. Receiver module can store remote control: 20
8. Support coding chip model: EV1527, PT2262, other customization
9. Weight: 26g
10. Remote control distance: 50 meters (if it is a remote control motor, the distance may be halved due to motor interference)

Wiring  instructions

The default mode for remote control shipment is jog mode. If you need to change the mode or multiple remotes control one receiver at the same time or one remote control multiple receivers, please do the following:

Clear code -

Press the learning pair button on the receiver 8 times in succession and the LED goes out. The LED flashes 8 times and clears OK. (If you need to change the working mode of the same remote control, please clear the code before learning)

 

Learning the code -

step1:

Press the learning button on the receiving board according to the number of times you need to select the working mode, and then the LED of the receiving board is always on.

Jog mode: Press the decoding module to learn the button once.

 

Self-locking mode: Press the decoding module to learn the button twice.

 

Interlock mode: Press the decoding module to learn the button 3 times.

 

Step 2: Press any button on the remote control to receive the received signal. After the receiver board LED flashes three times, it will go out and the code will be successful. (If you enter the learning pair code mode, there is no remote control signal, after 10 seconds, the learning pair code mode is automatically exited.)

Note: If you have selected a mode after clearing the code, then the first step to select other modes is invalid, you must clear the code and then learn! ! !

If you want to control multiple receivers at the same time, enter the learning mode, press the learning button LED, then press any button on the remote control.

Introduction to working mode

 

1. Jog: Press the remote control, the corresponding channel of the decoding module will output a high level signal instantaneously. If the button is pressed all the time, there will always be a high level output, and the release button will become a low level.

 

2. Self-locking: Press the remote control, the corresponding channel of the decoding module keeps the output level signal, and then press the remote control, the decoding module stops outputting the high level signal, that is, press the button once to change the state once.

 

 

3. Interlock: Press the remote control, the corresponding channel of the decoding module continuously outputs a high level signal, and forces other channels to output low level. (For example: press the remote control A button, the decoding module D0 pin outputs a high level signal, and the other three channels output a low level; press the B button, the decoding module D1 pin outputs a high level signal, and the other three channels output low. Level signal.)
