L298n hookup

How does the l298n work?

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 4.8 - 46V, with a peak current up to 2A per motor. For more details please visit:

What is the output voltage of the l298n Motor Driver module?

Logical input voltage up to 1.5 V The L298N Motor Driver module consists of an L298 IC Dual H-bridge, 5V 78M05 Voltage Regulator, resistors, capacitor, Power LED, 5V jumper. 2 DC motor output pins, 12-volt external motor power supply, motor direction control pins (IN1, IN2, IN3, IN4), motor output enable pins (ENA, ENB), and a heat sink.

What is a L298 IC?

L298 is a high voltage, high current dual full-bridge motor driver IC. It accepts standard TTL logic levels (Control Logic) and controls inductive loads such as relays, solenoids, DC and Stepper motors. This is a 15 pin IC.

Why does my l298n motor not work with a jumper?

Also DO NOT supply power to both the motor power supply input and 5V power supply input when jumper is in place. The voltage drop of the L298N motor driver is about 2V. This is due to the internal voltage drop in the switching transistors in the H-Bridge circuit.

What is an l298n module?

Introduction L298N module is a high voltage, high current dual full-bridge motor driver module for controlling DC motor and stepper motor. It can control both the speed and rotation direction of two DC motors. This module consists of an L298 dual-channel H-Bridge motor driver IC.

What is a l298n DC motor driver?

There are many DC motor drivers that have these features and the L298N is one of them. 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.

What determines the speed of the l298n motor?

The speed of the motor is determined by the width of the PWM pulse sent to the “Enable” input of the L298N motor driver. The wider the pulses, the faster the motor will spin.

What is the use of the L298 chip in a microcontroller?

L298 is a high voltage and high current motor drive chip which receives TTL logic signals. It is needed to operate different loads like motors and solenoid etc where an H-Bridge is required. High power motor driver is required.

What is the voltage drop of the l298n motor driver?

The voltage drop of the L298N motor driver is about 2V. This is due to the internal voltage drop in the switching transistors in the H-Bridge circuit. So, if we connect 12V to the motor power supply terminal, the motors will receive voltage around 10V.

Why does the l298n need a power supply?

The L298Ns needs power supply for its logic circuitry, so you have: - voltage for the motor - voltage for the L298N - signal lines Show activity on this post. I found this thread for a similar problem, I realized that my scratch (taken from here) wasnt able to works..

How do I connect my l298n motor to my Arduino?

Now, the input and enable pins (ENA, IN1, IN2, IN3, IN4 and ENB) of the L298N module are connected to six Arduino digital output pins (9, 8, 7, 5, 4 and 3). Note that the Arduino output pins 9 and 3 are both PWM-enabled. Finally, connect one motor to terminal A (OUT1 & OUT2) and the other motor to terminal B (OUT3 & OUT4).

How many jumpers does the l298n come with?

This type of board is usually shipped with three jumpers already in place. But in case they are missing or not set, you should verify their placement before proceeding. The L298N can be powered from 5V to 35V (depending on the specification).
