How do you power a L298N motor driver?

5V pin supplies power for the switching logic circuitry inside L298N IC. If the 5V-EN jumper is in place, this pin acts as an output and can be used to power up your Arduino. If the 5V-EN jumper is removed, you need to connect it to the 5V pin on Arduino. ENA pins are used to control speed of Motor A.

How do I test an H-Bridge?

To check if the board is working Give VCC and ground as usual. With the motor connected across AOUT1 and AOUT2 the motor should run in the forward direction. If you wish to provide PWM to control the speed of the motor send a pwm signal to AIN2 which is the enable pin (AIN2 is the phase/direction pin).

What is L298N driver?

The L298N is a dual H-Bridge motor driver which allows speed and direction control of two DC motors at the same time. The module can drive DC motors that have voltages between 5 and 35V, with a peak current up to 2A. Let’s take a closer look at the pinout of L298N module and explain how it works.

What do H bridges do?

An H-bridge is an electronic circuit that switches the polarity of a voltage applied to a load. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backwards.

How to connect l298n Motor Driver module with Raspberry Pi?

Coming to the Inputs of the Motor, connect the IN1 and IN2 of L298N Module to Physical Pins 16 and 18 (GPIO23 and GPIO24). That’s it. The rest of the job is done by the Python Script. The Python Script for Interfacing L298N Motor Driver Module with Raspberry Pi is given below.

What is the function of l298n optocoupler?

Equivalent to L298N can drive two dc motor or a stepper motor. The function of the optocoupler is to isolate the signal, so that L298N will not immediately feed back to the MCU if there is a problem, and the MCU will be burnt out.

How to disable the on-board 5V regulator of l298n Motor Driver module?

There is jumper near the power supply terminals of the L298N Motor Driver Module. If it is connected, it will enable the on-board 5V regulator, which supplies +5V logic supply for L298N IC. This must be used only if the supply voltage is less than or equal to +12V. If it is more than +12V, then disconnect the jumper to disable the regulator.

How do I trigger the motor on a Raspberry Pi?

The “GPIO” pins on the Raspberry PI will be used to “trigger” the l298n direction. There are TWO pins per motor. One pin drives the power, {+} to one lead when the pin is activated. If you have a PI2 or the newer B+ then there is a different pin layout for that. I did this one with the older base model B.
