Product Name

L298N Motor Drive Module Four way Motor Drive Intelligent Car Drive Motor Module


Overview

The LC four channel L298N motor drive module integrates two L298N chips and can drive four DC motors simultaneously,
achieving control over forward and reverse rotation as well as motor speed.
The module is equipped with an LM2596S voltage reducing chip,
which can output 5V power to the control terminal when driving motors with a voltage of 7V or higher

Single bridge maximum driving current 2A maximum total power consumption 20W


2. Instructions for use:

(1) L298N, as the main driver chip, has the characteristics of strong driving ability, low heat generation, and strong anti-interference ability. At the same time, the LM2596 switching power IC installed also maximizes power efficiency, lower power consumption, and stronger power

(2) Connecting the servo: The board carries three servo interfaces, each containing three pins: S, 5V, and GND. If the servo under ultrasound in this experiment is plugged into the first circuit, the yellow, red, and brown wires of the SG90 servo correspond to S1, 5V, and GND, respectively. The PWM signal for controlling the servo is input from pin A1 on the side, and the remaining servo interfaces can be used to power external 5V devices

(3) Connect VCC and GND to 18650 battery during use; IN1-IN8 are connected to the high and low levels output by Arduino to control the forward, reverse, and stop of the motor< EN1-EN4 are enable/speed control pins, and the speed can be adjusted by using a microcontroller to output PWM with variable duty cycle. If speed control is not required, jumper caps can be used to connect them to 5V on the L298N module (at full speed operation)

The following is the control logic for IN1-IN8 when controlling DC motors:

DC motor rotation mode IN1 IN2 IN3 IN4 IN5 IN6 IN7 IN8
M1 Forward rotation High Low
M1 Reverse Low High
M1 Stop Low Low
M2 Forward Rotation High Low
M2 Reverse Low High
M2 Stop Low Low
M3 Forward Rotation High Low
M3 Reverse Low High
M3 Stop Low Low
M4 Forward Rotation High Low
M4 Reverse Low High
M4 Stop Low Low

Note: If the program and the wiring of IN1-IN8 are correct but the direction of a certain motor is reversed, such as motor M1, then swapping the two wires OUT1 and OUT2 can be done
