L298N Dual H-Bridge Motor Driver Module

Dual-channel H-bridge motor driver module based on the L298N IC. Capable of driving two DC motors (or one stepper motor) with up to ~2 A per channel and motor supply voltages from ~5 V up to ~35 V (board-dependent). Includes an onboard 5 V regulator (activated via jumper) that can power the logic circuitry and, within limits, an external controller. Provides directional control and speed (PWM) control for motors, with built-in clamp diodes and a heat sink for handling power dissipation. Widely used in robotics and motor control projects.
