L298N Based Motor Driver Module- 2A
L298N 2A Based Motor Driver is a high power motor driver perfect for driving DC Motors and Stepper Motors (Now find out out a wide range of motors at solicstores.in).
The L298N is a dual H-Bridge motor driver that allows speed and direction control of two DC motors at the same time. The module can drive DC motors that have voltages between 5 and 35V, with peak current up to 2A.
The module has two screw terminal blocks for the motors A and B, and another screw terminal block for the Ground pin, the VCC for motor and a 5V pin which can either be an input or an output.
This depends on the voltage used at the motors VCC. The module has an onboard 5V regulator which is either enabled or disabled using a jumper. If the motor supply voltage is up to 12V we can enable the 5V regulator and the 5V pin can be used as an output, if the motor voltage is greater than 12V we must disconnect the jumper because those voltages will cause damage to the onboard 5V regulator. the 5V pin will be used as input as we need to connect it to a 5V power supply in order for the IC to work properly.
This IC has a voltage drop of about 2V. So, if we use a 12V power supply, the voltage at motors terminals will be about 10V, which means that we won’t be able to get the maximum speed out of our 12V DC motor.
The Enable A and Enable B pins are used for enabling and controlling the speed of the motor. If a jumper is present on this pin, the motor will be enabled and work at maximum speed, and if we remove the jumper we can connect a PWM input to this pin and in that way control the speed of the motor. If we connect this pin to a Ground the motor will be disabled.
The Input 1 and Input 2 pins are used for controlling the rotation direction of the motor A, and the inputs 3 and 4 for the motor B. Using these pins we actually control the switches of the H-Bridge inside the L298N IC. If input 1 is LOW and input 2 is HIGH the motor will move forward, and vice versa, if input 1 is HIGH and input 2 is LOW the motor will move backward. In case both inputs are the same, either LOW or HIGH the motor will stop. The same applies to the inputs 3 and 4 and the motor B.
- DC motor 1 “+” or stepper motor A+
- DC motor 1 “-” or stepper motor A-
- 12V jumper – remove this if using a supply voltage greater than 12V DC. This enables power to the onboard 5V regulator
- Connect your motor supply voltage here, a maximum of 35V DC. Remove 12V jumper if >12V DC
- 5V output if 12V jumper in place, ideal for powering your Arduino (etc)
- DC motor 1 enables a jumper. Leave this in place when using a stepper motor. Connect to PWM output for DC motor speed control.

- In2: Enable Motor A
- In3: Enable Motor B
- In4: Enable Motor B
- DC motor 2 enables a jumper. Leave this in place when using a stepper motor. Connect to PWM output for DC motor speed control.
- DC motor 2 “+” or stepper motor B+
- DC motor 2 “-” or stepper motor B-
- High operating voltage, which can be up to 40 volts
- Large output current, the instantaneous peak current can be up to 2A
- With 25W rated power
- Two built-in H-bridge, high voltage, large current, full-bridge driver.
- Using a standard logic level signal to control.
- The module can utilize the built-in stabilivolt tube 78M05 to obtain 5v from the power supply.
- Drive voltage: 5-35V; logic voltage: 5V
- Heatsink for better performance
