The L298N dual H-bridge driver module is a high-current, high-voltage board designed to control two DC motors independently or one bipolar two-phase stepper motor in robotics, CNC, and automation projects. Built around the ST L298N dual full-bridge driver chip, this DC stepper motor driver module accepts a motor supply voltage from 5V to 35V and delivers up to 2A of continuous current per channel, with a peak capability of 3A per channel and a maximum power rating of 25W. An onboard 78M05 5V regulator can supply logic power to a microcontroller or external circuit when the motor supply is below 12V; for higher drive voltages, the regulator jumper must be removed and logic power supplied externally. Each channel has independent enable inputs for PWM speed control, and direction is set by logic-level signals, allowing the module to function as a 2-channel motor controller for forward, reverse, stop, and standby operations.
Freewheeling diodes protect the circuit against back-EMF generated during motor deceleration or stopping. The module measures 43mm × 43mm × 27mm and weighs approximately 30g, with screw terminals for secure motor and power connections. Its compact footprint and high current capability make it a common choice for robot motor driver board applications in educational and industrial prototypes.
