L298N Motor Driver Module Dual H-Bridge DC Stepper 5V

L298N Motor Driver Module – Dual H-Bridge DC & Stepper Motor Driver (5V)

The L298N Motor Driver Module is the most popular dual H-bridge motor driver in the maker community. It can independently control two DC motors or one bipolar stepper motor, with direction and speed control via PWM signals from any microcontroller. The onboard 5V regulator also powers your Arduino or ESP32 directly from the motor supply.

Key Specifications

• Driver IC: L298N (ST Microelectronics)
• Motor Supply Voltage: 5V – 35V DC
• Logic Supply Voltage: 5V (onboard regulator from motor supply)
• Output Current: Up to 2A per channel (4A peak)
• Channels: 2 (dual H-bridge)
• Control: PWM speed control + direction pins
• Enable Pins: ENA, ENB (PWM or jumper for full speed)
• Protection: Thermal shutdown, onboard flyback diodes

Compatibility & Use Cases

Directly compatible with Arduino, ESP32, NodeMCU, and Raspberry Pi via standard GPIO and PWM pins. Common applications include:

• 2WD and 4WD wheeled robot chassis motor control
• Bipolar stepper motor control for CNC and 3D printer axes
• Conveyor belt and linear actuator control
• Bluetooth and WiFi-controlled RC car builds
• Line follower and obstacle-avoiding robot projects

Remove the ENA/ENB jumpers and connect PWM signals for variable speed control, or leave jumpers in place for full-speed operation.
