L298N Dual H-Bridge Motor Driver Module — DC & Stepper, 2A, 5–35V
The L298N motor driver module is the most widely used dual H-bridge motor driver for Arduino robotics and automation projects. It drives two DC motors or one bipolar stepper motor at up to 2A per channel from a 5–35V supply, with onboard 5V regulator to power the Arduino directly from the motor supply. PWM speed control and direction control are handled via simple digital GPIO pins.

Wiring Guide (Arduino)
- ENA → Arduino PWM pin (speed control motor A)
- IN1, IN2 → Arduino digital pins (direction motor A)
- IN3, IN4 → Arduino digital pins (direction motor B)
- ENB → Arduino PWM pin (speed control motor B)
- 12V → Motor supply (6–35V)
- 5V out → Arduino 5V pin (powers Arduino)
- GND → Common ground
Why Choose L298N?
