How Does the MX1508 Motor Driver Work?

The MX1508 Dual H-Bridge Motor Driver contains two independent H-bridge circuits.

An H-bridge controls the direction of current flowing through a brushed DC motor. By changing the input signals, a microcontroller can reverse the motor's rotation.

The MX1508 uses four control inputs. Each pair of inputs controls one motor channel:

• IN1 and IN2: Control Motor A
• IN3 and IN4: Control Motor B

PWM signals can be applied to the control inputs to adjust the effective motor drive and control speed.

The actual physical rotation direction depends on how the motor leads are connected.

Verify the labels on your actual PCB before connecting motors or a power supply.

Arduino UNO Connection

A typical MX1508 connection with Arduino UNO is:

These Arduino pin assignments are examples. Other suitable digital or PWM-capable pins may be used according to the software.

Important: Use an appropriate external motor power supply and connect its ground to the Arduino ground. Do not assume the Arduino 5V output can safely power the motors.

ESP32 Compatibility

The MX1508 can be controlled using suitable ESP32 GPIO outputs because its control inputs support low-voltage digital logic.

Use appropriate GPIO pins for the four control inputs and connect the ESP32 ground to the motor driver ground.

Motor power must be supplied separately from a compatible source. Ensure the motor driver and ESP32 receive power within their respective electrical limits.

PWM Speed Control

The MX1508 supports motor speed control through pulse-width modulation.

Using PWM, a controller rapidly switches the motor driver input between appropriate logic states.

Changing the PWM duty cycle changes the average motor drive, allowing approximate control of motor speed.

Actual motor performance depends on supply voltage, load, PWM frequency, and motor characteristics.

Two DC Motors or One Stepper Motor

The two H-bridge channels can independently drive two suitable brushed DC motors.

They may also be used to energize the two windings of a small bipolar stepper motor using the appropriate control sequence.

Note: The MX1508 is not a dedicated current-regulated stepper driver. Use a suitable stepper motor driver for applications requiring precise current limiting or microstepping.

MX1508 vs L298N Motor Driver

• MX1508: Compact low-voltage dual H-bridge board for small motors and lightweight robotics.
• L298N: Larger motor driver module that supports higher motor supply voltages and is commonly used in general-purpose robotics.

Choose the MX1508 when small PCB size and low-voltage motor control are priorities.

MX1508 vs TB6612FNG

• MX1508: Simple compact motor driver for suitable low-voltage brushed DC motors.
• TB6612FNG: A separate dual H-bridge driver family with different supply, control and output current specifications.

Select the driver according to motor stall current, supply voltage, heat dissipation, and the control features required by your project.

Why Choose the MX1508?

Compact Design: Suitable for small smart cars and miniature robots.

Dual Motor Control: Operates two brushed DC motors independently.

PWM Support: Provides basic speed control using microcontroller PWM signals.

Simple Interface: Uses four digital input connections for motor direction and switching control.

Low-Voltage Operation: Suitable for many small battery-powered motor projects.

Educational Value: Useful for learning H-bridge circuits and motor-control programming.

Important Safety and Usage Notes

• Use a motor supply within the recommended 2V to 9.6V range.
• Do not exceed the MX1508 IC's 10V absolute maximum motor supply rating.
• Check motor stall current before connecting the motor.
• Continuous current ratings are different for the two channels under simultaneous operation.
• Do not treat peak current ratings as continuous ratings.
• Use suitable wiring and an appropriately rated external power source.
• Connect the microcontroller and motor driver grounds together.
• Observe correct motor supply polarity.
• Do not connect the module directly to AC mains.
• The motor driver may heat up during high-current operation.
• Thermal shutdown does not replace proper current limiting and circuit protection.
• Do not connect loads that exceed the driver output capability.
• Verify the physical board markings and pin layout before installation.
