L298P Motor Driver – Control Powerful DC and Stepper Motors with Arduino

Expansion Shield with Dual H-Bridge, Current Sensing and TinkerKit Compatibility

The L298P 4A Dual Channel Motor Driver Module / Motor Shield R3 for Arduino is an Arduino-compatible motor driver shield designed to control two DC motors independently or one bipolar stepper motor. Built around the L298P dual full-bridge driver, this shield allows independent speed and direction control with PWM input and optional current sensing.

Key Features:

• Dual Channel Motor Control: Drives 2 DC motors or 1 stepper motor.

• Operating Voltage: approx 5 V to 12 V (external supply preferred).

• Max Current: up to 2 A per channel or 4 A total (with proper external power).

• Current Sensing: feedback available via analog outputs (e.g., A0/A1).

• Stop & Brake Function: supports both free-run stop and active braking.

• Arduino Shield R3 Compatible: plugs directly onto Arduino Uno R3 and compatible boards.

• TinkerKit Compatible: includes interfaces for easy integration with other modules.

Applications:
✔ DC motor speed control and direction management.
✔ Stepper motor driving for robotics or CNC mini projects.
✔ RC car motor control and motion systems.
✔ Sensor feedback and current monitoring for advanced control routines.

Note: To ensure stable and safe operation, connect an external power source to the motor power inputs rather than relying solely on the Arduino’s USB power.
