The L298N is a versatile motor driver used for controlling high powered motors with low voltage / low current microcontrollers.
Since it is an H-Bridge, it can drive the motor forward or backwards.
The L298N allows for voltages from 5V to 35V (24V max suggested) and is perfect for 12VDC robotic and R/C motors. It supports up to 2 amps, with a maximum power of 25 watts.
The board features heat sink, large capacitors, protection diodes, and ports for two motors.
