Specification: Chip: L298N Logic voltage: 5V Logic current 0mA-36mA Maximum power: 25W Drive voltage: 5V-35V Drive current: 2A(For each DC motor) Operating mode: Dual H-bridge driver (can drive 2 DC motors) Reason 1: Use L298N for Main Chip L298N is a kind of high voltage, high current motor driver chip. Features as high working voltage (maximum voltage up to 46V), large output current (instantaneous peak current up to 3A), continuous working current 2A and 25W of rated power. Having 15 pins as package. Two built-in H Birdge high voltage and large current full bridge drivers can be used to drive the DC motor and stepper motor, relay coil and so on. The chip can connects to external detecting resistor to give the variations to the control circuit. Reason 2: Wide Application size: 43 x 43 x 27mm Material: PCB colour: red Package Contents: 2 x L298N Motor Drive Controller Board Module
