Motor Drive Module L298N

This module is integrated with a built-in 5V power.When the drive voltage is 7V-35V, it can enable the onboard 5V logic power supply;afterthe power supply,don't input voltage in the interface+5V power supply,but you can lead the 5V for external use.

when ENA enable IN1 IN2 control OUT1 OUT2

when ENB enable IN3 IN4 control OUT3 OUT4

Applied cases:

1 Driving stepper motor

The connection of driving a common 4 line 2 phase electric motor is shown in below figure

after enable ENA ENB

Input the following driving timing from IN1-IN4，then the speed and direction of the stepper

motor can be controlled

2 Driving DC motor

Because the module is drived by double H bridge,it can drive two motors simultaneously.

The connecting method is shown inbelow figure

after enable ENA ENB

You can imput the speed and direction of PWM signal drive motor 1 from IN1 IN2

You can imput the speed and direction of PWM signal drive motor 2 from IN1 IN2

The signal is shown in the figure
