Important Usage Note
When using a drive voltage greater than 12V, please use an external 5V logic power supply to avoid overloading the onboard 78M05 voltage regulator. For drive voltages of 12V or below, the onboard regulator can supply 5V logic power directly.

Frequently Asked Questions
Q: Can the L298N motor driver module control two DC motors simultaneously?
A: Yes! The L298N module features a dual H-bridge design, which means it can independently control two DC motors at the same time — each with its own speed (via PWM) and direction control. This makes it ideal for two-wheel drive robot cars and similar projects.
Q: Is this L298N module compatible with Arduino?
A: Absolutely. This module is one of the most popular motor driver choices for Arduino-based projects. It operates on 5V logic, which matches the Arduino's digital output pins directly. Simply connect the IN1–IN4 pins to your Arduino's digital pins, and the motor outputs to your motors.
Q: When should I use an external 5V power supply for the logic?
A: When your motor drive voltage exceeds 12V, you should supply 5V logic power externally. The onboard 78M05 regulator is rated for use up to 12V drive voltage; beyond that, the voltage drop across the regulator becomes too large and may cause it to overheat or fail. Use a separate regulated 5V source for the logic pins in those cases.
Q: Can this module drive a stepper motor?
A: Yes. The L298N dual H-bridge can drive a 4-wire bipolar stepper motor by using both H-bridge channels together. This makes it useful for CNC-style positioning, camera sliders, and other stepper motor applications in addition to standard DC motor control.
