The ZHIYU ZPB30A1P is easy to use in a variety of motor control applications. Follow the steps below to integrate it into your circuit:

1. Power Supply: Connect the VCC pin to a DC power source (6V to 30V) and the GND pin to ground.
2. Motor Connections: Connect the motor terminals to OUT1 and OUT2.
3. Control Pins:
   • Connect IN1 and IN2 to a microcontroller or control circuit to set the motor direction.
   • Use the EN pin to enable or disable the motor driver.
   • Connect the PWM pin to a PWM-capable pin on your microcontroller for speed control.

Below is an example of how to connect the ZHIYU ZPB30A1P to an Arduino UNO to control a DC motor:

• Connect the VCC pin to a 12V DC power source.
• Connect the GND pin to the ground of both the power source and the Arduino.
• Connect IN1 to Arduino digital pin 7.
• Connect IN2 to Arduino digital pin 8.
• Connect EN to Arduino digital pin 9.
• Connect PWM to Arduino digital pin 10.
• Connect the motor terminals to OUT1 and OUT2.

// Define motor control pins
const int IN1 = 7;  // Motor direction control pin 1
const int IN2 = 8;  // Motor direction control pin 2
const int EN = 9;   // Motor enable pin
const int PWM = 10; // Motor speed control (PWM) pin

void setup() {
  // Set motor control pins as outputs
  pinMode(IN1, OUTPUT);
  pinMode(IN2, OUTPUT);
  pinMode(EN, OUTPUT);
  pinMode(PWM, OUTPUT);

  // Initialize motor in stopped state
  digitalWrite(EN, LOW);  // Disable motor
  digitalWrite(IN1, LOW); // Set direction to neutral
  digitalWrite(IN2, LOW); // Set direction to neutral
}

void loop() {
  // Example: Rotate motor forward at 50% speed
  digitalWrite(EN, HIGH);  // Enable motor
  digitalWrite(IN1, HIGH); // Set direction forward
  digitalWrite(IN2, LOW);
  analogWrite(PWM, 128);   // Set speed (128 = 50% duty cycle)

  delay(5000); // Run motor for 5 seconds

  // Example: Rotate motor backward at 75% speed
  digitalWrite(IN1, LOW);  // Set direction backward
  digitalWrite(IN2, HIGH);
  analogWrite(PWM, 192);   // Set speed (192 = 75% duty cycle)

  delay(5000); // Run motor for 5 seconds

  // Stop the motor
  digitalWrite(EN, LOW);   // Disable motor
  delay(2000); // Wait for 2 seconds before repeating
}

• Power Supply: Ensure the power supply voltage matches the motor's operating voltage.
• Current Limit: Adjust the current limit to protect the motor and driver from overcurrent conditions.
• Heat Dissipation: Use a heat sink or active cooling if the driver operates at high currents for extended periods.
• PWM Frequency: Use a PWM frequency within the specified range (up to 20 kHz) for optimal performance.

1. Motor Not Running:

   • Check if the EN pin is set to HIGH.
   • Verify the power supply voltage and connections.
   • Ensure the motor is properly connected to OUT1 and OUT2.

2. Motor Running in the Wrong Direction:

   • Swap the logic levels of IN1 and IN2.
   • Verify the motor connections to OUT1 and OUT2.

3. Overheating:

   • Ensure the current limit is properly adjusted.
   • Add a heat sink or cooling fan to the driver.

4. PWM Not Controlling Speed:

   • Verify the PWM signal is within the 3.3V to 5V logic range.
   • Check the PWM frequency and duty cycle settings.
