The Dual DC Motor Drive Module (7A/160W) is an industrial-grade PWM speed control driver designed to operate two DC motors simultaneously with high efficiency and stability. Featuring a double H-Bridge design, it provides up to 7A continuous current per channel and a peak current of 50A, making it ideal for medium to high-power motor applications. With wide voltage support (6.5V–27V), optocoupler-isolated signal inputs, and built-in protection circuits, this module ensures safe and interference-free operation. It includes undervoltage protection, TVS surge suppression, and static discharge resistance to deliver reliable performance in demanding environments. Perfect for robotics, automation, and DIY projects requiring robust motor control. Featured By RoboticsBD.

Documentation:
Suitable for motor parameters :
- For motors with rated voltage of 24V, it is suitable to identify the rated power of 115W and below or the rated current of 7A or less.
- For motors with rated voltage of 12V, it is suitable to identify the rated power of 40W and below or the rated current of 7A or less.
Precautions:
- The driver power supply must not be reversed. It is recommended to connect the 15A fuse in series at the power interface. The voltage should be between6.5 and 27V. If the voltage is overvoltage, powering up may burn the drive module.
- It is recommended that the rated output current of the power supply be more than 2 times of the rated current of the motor , so as not to cause the power supply to supply the current required by the motor to cause the power supply voltage to drop, so that the power supply voltage does not reach the input voltage required by the driver, so that the drive module performs Undervoltage protection. The broken output causes the motor to stall.
- The motor interface must not be short-circuited, otherwise, the drive module may be burned. It is recommended to connect the 10A fuse at the motor interface.
- In the forward and reverse switching, you need to brake for more than 0.1Sand then reverse. It can't be reversed when the motor has not stopped. Otherwise, the drive may be damaged.
- When the drive module is powered down, do not rotate the motor directly or indirectly at high speed, otherwise, the electromotive force generated by the motor may burn the drive module. If the application needs to rotate the motor at high speed when the drive module is powered down, it is recommended to connect a relay (the NO and COM terminals are connected in series) to the motor interface of the drive. The relay coil and the driver are connected to the power supply. Thus, when the power supply is powered down, the relay disconnects the drive from the motor.
- Be careful not to get wet of the drive. Do not short-circuit the components on the drive board. Do not touch the pins and pads of the components on the board.
