Package Includes:

  • 1 x Mini L298N 1.5A Dual Channel DC Stepper Motor Driver Module

📌 Code Examples & Usage – Mini L298N 1.5A Dual Motor Driver Module

📋 Overview

This Mini L298N 1.5A dual channel motor driver module is a compact H-bridge driver designed for controlling:

  • 2 × small DC motors

  • 1 × small bipolar stepper motor

It’s suitable for low-to-moderate current applications such as robot cars, small actuators, conveyors, and educational robotics, and works with Arduino, ESP32, ESP8266, Raspberry Pi, and PLC digital outputs.

⚙ Key Features

  • Dual H-bridge outputs

  • Rated current: ~1.5A per channel

  • Motor voltage: ~5–24V DC (depending on module specs)

  • Logic interface: 3.3V – 5V compatible

  • PWM speed control plus direction control

📌 More efficient and smaller than classic full-size L298N modules.

⚠ IMPORTANT – Power & Current Notes

🚨 Continuous current limited (~1.5A)
✔ Good for small DC motors (TT, micro gear motors)
✔ OK for small stepper motors with low current draws

❌ Not suitable for:

  • Large steppers (e.g., NEMA 17 at rated currents)

  • High-torque DC motors drawing >1.5A

  • Long or continuous heavy loads without heatsinking

📌 If you need higher current or efficiency, consider:

  • TB6612FNG (better efficiency)

  • BTS7960 / MOSFET-based drivers

🔌 Pinout & Connections

Most mini L298N modules provide:

Pin Function
EN A PWM speed control Motor A
IN1 / IN2 Direction Motor A
EN B PWM speed control Motor B
IN3 / IN4 Direction Motor B
VM Motor supply (5–24V DC)
GND Ground
VCC (optional) Logic supply (5V)

| Motor A | OUT1 / OUT2 |
| Motor B | OUT3 / OUT4 |

📌 Logic VCC often comes from your microcontroller’s 5V.

🔌 Power Setup

  • Motor supply (VM): 5–24V DC (motor dependent)

  • Logic supply: 5V (microcontroller)

  • Common ground: Motor supply and logic ground must be tied

⚠ If your module has a 5V regulator jumper, follow the module’s markings — if not, use a separate 5V logic supply.

🧪 1️⃣ DC Motor – Direction & Speed Example

int ENA = 5, IN1 = 8, IN2 = 9;
int ENB = 6, IN3 = 10, IN4 = 11;

void setup() {
pinMode(ENA, OUTPUT); pinMode(IN1, OUTPUT); pinMode(IN2, OUTPUT);
pinMode(ENB, OUTPUT); pinMode(IN3, OUTPUT); pinMode(IN4, OUTPUT);
}

void loop() {
// Motor A forward
digitalWrite(IN1, HIGH);
digitalWrite(IN2, LOW);
analogWrite(ENA, 180); // Speed 0-255

// Motor B reverse
digitalWrite(IN3, LOW);
digitalWrite(IN4, HIGH);
analogWrite(ENB, 180);

delay(2000);

// Stop
analogWrite(ENA, 0);
analogWrite(ENB, 0);
delay(1000);

// Reverse directions
digitalWrite(IN1, LOW);
digitalWrite(IN2, HIGH);
digitalWrite(IN3, HIGH);
digitalWrite(IN4, LOW);

analogWrite(ENA, 180);
analogWrite(ENB, 180);
delay(2000);

analogWrite(ENA, 0);
analogWrite(ENB, 0);
delay(1000);
}

🧪 2️⃣ PWM Speed Control (Independent)

void setMotorA(int speed) { // speed -255 to 255
if (speed > 0) { digitalWrite(IN1, HIGH); digitalWrite(IN2, LOW); }
else { digitalWrite(IN1, LOW); digitalWrite(IN2, HIGH); speed = -speed; }
analogWrite(ENA, constrain(speed, 0, 255));
}

void setMotorB(int speed) {
if (speed > 0) { digitalWrite(IN3, HIGH); digitalWrite(IN4, LOW); }
else { digitalWrite(IN3, LOW); digitalWrite(IN4, HIGH); speed = -speed; }
analogWrite(ENB, constrain(speed, 0, 255));
}

void loop() {
setMotorA(200); setMotorB(200);
delay(3000);
setMotorA(-200); setMotorB(-200);
delay(3000);
setMotorA(0); setMotorB(0);
delay(2000);
}

🧪 3️⃣ Bipolar Stepper Motor – Basic Sequence

You can drive a small 4-wire bipolar stepper by using both H-bridges:

int IN1 = 8, IN2 = 9, IN3 = 10, IN4 = 11;

void setup() {
pinMode(IN1, OUTPUT); pinMode(IN2, OUTPUT);
pinMode(IN3, OUTPUT); pinMode(IN4, OUTPUT);
}

void stepMotor(int step) {
switch (step % 4) {
case 0:
digitalWrite(IN1, HIGH); digitalWrite(IN2, LOW);
digitalWrite(IN3, HIGH); digitalWrite(IN4, LOW);
break;
case 1:
digitalWrite(IN1, LOW); digitalWrite(IN2, HIGH);
digitalWrite(IN3, HIGH); digitalWrite(IN4, LOW);
break;
case 2:
digitalWrite(IN1, LOW); digitalWrite(IN2, HIGH);
digitalWrite(IN3, LOW); digitalWrite(IN4, HIGH);
break;
case 3:
digitalWrite(IN1, HIGH); digitalWrite(IN2, LOW);
digitalWrite(IN3, LOW); digitalWrite(IN4, HIGH);
break;
}
}

void loop() {
for (int i = 0; i < 200; i++) {
stepMotor(i);
delay(5);
}
}

📌 For serious stepper control, consider drivers with microstepping.

🔋 Power & Heat Notes

✔ Use a separate motor supply sized to your motor voltage
✔ Shared ground is required
✔ Expect some heat at higher loads — consider airflow
✔ Keep motor wires short

🧠 Common Issues & Fixes

Issue Cause Fix
Motor not turning Wiring error Swap motor leads
Weak torque Low voltage Increase supply within spec
Driver overheats High current Use TB6612 / MOSFET drivers
