Description
L298N Dual H-Bridge 2A DC Stepper Motor Driver Controller Module
The L298N Dual H-Bridge Motor Driver Module is a versatile motor-control board designed for controlling DC motors and stepper motors in robotics, automation, and DIY electronics projects. Based on the popular L298N dual H-bridge driver IC, the module provides two motor-control channels and can handle motor supply voltages from 5V to 35V DC. It supports up to 2A per channel, making it suitable for a wide range of small and medium motor-control applications. The module can be controlled using Arduino, Raspberry Pi, microcontrollers, switches, relays, and other compatible control systems. Direction and speed can be controlled through the module's input pins, making it useful for robotic vehicles, mechanisms, and mechatronics projects. An integrated heatsink helps dissipate heat during operation. The board also includes useful features such as power indication, current sensing, direction control, and onboard logic-power connectivity.
