Working Principle
The module uses two H-bridge motor-control circuits to control the direction and speed of connected motors.
By changing the logic states of the input pins, the controller can command each motor to:
- Rotate forward
- Rotate reverse
- Stop
- Brake
PWM signals can also be applied to the control inputs to regulate motor speed.
The two H-bridge channels can be operated independently, allowing differential-drive robots and other two-motor systems to perform turning and directional movement.
DC Motor Control
The module can independently control two DC motors. This makes it particularly useful for two-wheel robotic platforms where each motor can be controlled separately.
For example:
- Both motors forward → Robot moves forward
- Both motors reverse → Robot moves backward
- One motor slower → Robot turns
- One motor forward and one reverse → Robot can rotate in place
Actual motor performance depends on the motor specifications, supply voltage, load, and thermal conditions.
Stepper Motor Support
The two H-bridge channels can also be used to control a compatible 4-wire bipolar stepper motor.
A suitable control sequence must be generated by the connected microcontroller to energize the motor windings in the required order.
Logic Compatibility
The input control pins are designed to work with common digital logic levels, including:
- 1.8V
- 3.3V
- 5V
This provides convenient compatibility with development platforms such as Arduino, ESP32, Raspberry Pi, STM32, and other microcontrollers.
PWM Speed Control
PWM can be used to control the effective motor power and adjust DC motor speed.
By changing the PWM duty cycle, the user can vary motor speed according to the requirements of the application.
The actual usable PWM frequency and motor response depend on the motor, controller, supply voltage, and application.
Typical Application Scenarios
Micro-Mouse Robots
The compact size and high current capability make the module suitable for high-speed micro-mouse and compact competitive robots.
Line-Following Robots
PWM speed control allows independent adjustment of left and right motors for precise navigation and turning.
Robotic Arms
The small form factor makes the module suitable for controlling compact DC motors in robotic joints and mechanisms.
DIY Mobile Robots
It can be used in two-wheel and four-wheel robotic platforms requiring compact motor-control electronics.
LED and Inductive Loads
The H-bridge outputs can also be used for suitable inductive or PWM-controlled loads within the module’s electrical limits.

Important Notes
Power Supply
Use a suitable DC supply within the specified 2V–10V range. Ensure the power source can provide the required motor current.
Motor Current
Motors can draw significantly higher current during startup, acceleration, stall conditions, or sudden load changes. Ensure the motor driver and power supply are appropriately rated.
Thermal Management
When operating at higher current levels, provide sufficient airflow and heat dissipation to prevent excessive temperature rise.
Logic Ground
Connect the controller ground and motor-driver ground correctly to provide a common reference for the control signals.
