Microcontroller that normally operates on 5V or 3.3V cannot be directly used to control a DC motor operating on higher voltage and current rating. This is why we commonly use Motor Driver modules like the L293D Motor Driver Module and the L298N Motor Driver Module. While the L293D motor driver module can be used for basic low current application the L298N Motor driver module is a high current motor driver with some additional features that are commonly used with Arduino and Raspberry Pi for Robotics applications.

The L298N Motor Driver module is based on the L298 Dual Full-Bridge Driver IC and can control the speed and direction of two DC motors (Motor A and Motor B) simultaneously. The voltage rating of these motors can be between 5V to 35V and the peak current value can be up to 2A.
