Overview

2x7A DC Motor Driver is a high-current dual-channel motor driver designed for robotics and motion projects that need far more power than typical hobby motor drivers can handle. It can drive 2 DC motors, with up to 7A continuous current per channel and a peak current rating of 50A.

The board supports PWM speed control and accepts control logic compatible with both 3.3V and 5V systems, making it easy to interface with Arduino, ESP-based boards, and other common microcontrollers. The pluggable connectors also simplify wiring for prototypes and serviceable builds.

This driver is a strong fit for mobile robots, heavy-duty wheeled platforms, actuators, and other DC motor applications where reliable high-current switching is important. Reference material also notes features such as UVLO, ESD protection, and opto-isolated inputs.

How it works

Each motor channel uses two direction inputs and one PWM enable input. Set the direction with the IN pins, then apply PWM on ENA or ENB to control speed. The supported control modes are brake, forward, reverse, and PWM speed control in either direction.

IN = 0/0: stop (brake)
IN = 1/0 + EN high: forward
IN = 0/1 + EN high: reverse
IN = 1/0 or 0/1 + EN PWM: variable-speed forward or reverse

Important notes

Before changing motor direction, brake first by setting the control inputs low. This is especially important at full PWM duty cycle.
The suggested braking time is more than 0.1 second, depending on the motor.
The +5V reference input must be connected to the same 3.3V or 5V supply used by your controller.
Use a 20A fuse between the power source and the driver.
The back of the board includes large bare traces. Avoid contact with conductive surfaces, and add insulation if needed.

Applications

Suitable for high-current robot drivetrains, differential drive platforms, custom RC builds, motorized mechanisms, and other projects that need a robust dual DC motor driver with microcontroller-friendly control signals.

Frequently Asked Questions

What motors can this 2x7A DC Motor Driver control?

This is a dual-channel driver for 2 DC motors. Each channel supports up to 7A continuous operating current, with a stated peak current of 50A.

What input voltage does this motor driver require?

The recommended motor power supply range is DC 7V to 24V. The stated supply limit is 6.5V to 27V.

Is this motor driver compatible with 3.3V and 5V microcontrollers?

Yes, the control signal inputs are compatible with both 3.3V and 5V logic systems. The +5V reference input must be connected to the same 3.3V or 5V supply used by your controller.

How is speed and direction controlled on this board?

Direction is controlled using IN1/IN2 for Motor 1 and IN3/IN4 for Motor 2, while ENA and ENB are used for PWM speed control. The minimum valid PWM pulse width is 5 microseconds.

How do I safely reverse motor direction with this driver?

Before changing direction, the guide recommends braking the motor first by setting both direction inputs low, such as IN1=0 and IN2=0. A braking time greater than 0.1 second is suggested, especially when running at full speed.

What are the size and mounting details of this driver board?

The board measures 55 x 55 mm and weighs 32g. It includes M3 mounting holes for installation.
