TB6612FNG Setup and Usage

What Is the TB6612FNG Motor Driver?

The TB6612FNG is a compact and efficient dual-channel motor driver capable of controlling two DC motors or a stepper motor with high precision and low heat generation.

Connecting the TB6612FNG

• PWMA/PWMB: Motor speed control
• AIN1/AIN2: Control Motor A direction
• BIN1/BIN2: Control Motor B direction
• VCC: Logic power (3.3V–5V)
• VM: Motor voltage (4.5V–13.5V)

Arduino Example Code

#define AIN1 9
#define AIN2 8
#define PWMA 10

void setup() {
    pinMode(AIN1, OUTPUT);
    pinMode(AIN2, OUTPUT);
    pinMode(PWMA, OUTPUT);
}

void loop() {
    digitalWrite(AIN1, HIGH);
    digitalWrite(AIN2, LOW);
    analogWrite(PWMA, 128);
    delay(2000);

    digitalWrite(AIN1, LOW);
    digitalWrite(AIN2, HIGH);
    analogWrite(PWMA, 128);
    delay(2000);
}
