L298N Motor Driver Module details: L298N motor driver Module And to supply the voltage/current required to operate the motor, an external supply is connected to the motor driver module.

We bridge the gap between the Arduino and motor by introducing a motor driver between them. To solve this problem the use of a motor driver is essential. Hence the output of Arduino is not enough to power up the motors. Also, the output current limit of Arduino is relatively very low.

But a decent DC motor needs at least 5V or 12V. For instance, the Arduino or PIC microcontroller can output a maximum voltage of 5V or 3.3V. Why do we need a motor driver module?Īll microcontrollers operate on low-level voltage/current signals, unlike motors. The IC alone can control the DC motor but using the module makes the interfacing with Arduino easy. The motor driver module consists of a motor driver IC, which is the heart of the module. To put it in simple words, you can control the direction of DC motors by giving appropriate logic to the motor driver module. This input logic controls the direction of DC motors connected to the driver. A motor driver module takes the low voltage input from a controller like Arduino. It is commonly used in autonomous robots and RC cars (L2938N and L293D are the most regularly utilized motor driver chips). What is a Motor Driver Module? Motor DriversĪ motor driver module is a simple circuit used for controlling a DC motor. But first, we must answer some basic questions like what is a motor driver, why is it used in a circuit, and what is an H-bridge configuration, etc. In this article, you will learn about the L298N motor driver module in detail.
