Below are the key technical details of the Keyestudio 5V Stepper Motor Driver Module:

The module features a simple pinout for easy connection to microcontrollers and stepper motors:

1. Power Supply: Connect the VCC pin to a 5V power source and the GND pin to the ground.
2. Motor Connection: Attach the 5 wires of the stepper motor to the motor output pins on the module.
3. Microcontroller Interface: Connect the IN1, IN2, IN3, and IN4 pins to the digital output pins of your microcontroller (e.g., Arduino).
4. Programming: Write a program to send step sequences to the IN pins to control the motor's movement.

• Ensure the motor's current rating does not exceed the module's maximum output current.
• Use a separate power supply for the motor if it requires higher current than the microcontroller can provide.
• Avoid disconnecting the motor while the module is powered to prevent damage.

Below is an example code to control a stepper motor using the Keyestudio 5V Stepper Motor Driver Module:

// Define the pins connected to the stepper motor driver module
#define IN1 8  // Connect to IN1 on the module
#define IN2 9  // Connect to IN2 on the module
#define IN3 10 // Connect to IN3 on the module
#define IN4 11 // Connect to IN4 on the module

// Define the step sequence for the stepper motor
int stepSequence[4][4] = {
  {1, 0, 0, 1}, // Step 1
  {1, 0, 1, 0}, // Step 2
  {0, 1, 1, 0}, // Step 3
  {0, 1, 0, 1}  // Step 4
};

void setup() {
  // Set the IN pins as outputs
  pinMode(IN1, OUTPUT);
  pinMode(IN2, OUTPUT);
  pinMode(IN3, OUTPUT);
  pinMode(IN4, OUTPUT);
}

void loop() {
  // Rotate the motor in one direction
  for (int i = 0; i < 4; i++) {
    setStep(stepSequence[i]);
    delay(10); // Adjust delay for speed control
  }
}

// Function to set the step sequence
void setStep(int step[4]) {
  digitalWrite(IN1, step[0]);
  digitalWrite(IN2, step[1]);
  digitalWrite(IN3, step[2]);
  digitalWrite(IN4, step[3]);
}

• Adjust the delay() value in the loop() function to control the motor's speed.
• Reverse the order of the step sequence to change the motor's direction.

1. Motor Not Moving:

   • Verify all connections, especially the motor wires and IN pins.
   • Ensure the power supply is providing a stable 5V.
   • Check the step sequence in the code for accuracy.

2. Motor Vibrates but Does Not Rotate:

   • Ensure the step sequence matches the motor's wiring configuration.
   • Reduce the delay between steps to provide smoother operation.

3. Overheating Module:

   • Check if the motor's current exceeds the module's rating.
   • Use a heat sink or active cooling if necessary.

4. Erratic Movement:

   • Verify that the microcontroller's ground is connected to the module's ground.
   • Ensure the power supply is not fluctuating.

Q1: Can I use this module with a 3.3V microcontroller?
A1: Yes, but you must ensure the logic level of the IN pins is compatible with 3.3V signals.

Q2: What type of stepper motors are compatible?
A2: The module is designed for 4-phase, 5-wire stepper motors. Ensure the motor's voltage and current ratings match the module's specifications.

Q3: How do I reverse the motor's direction?
A3: Reverse the order of the step sequence in your code to change the motor's rotation direction.

Q4: Can I control multiple motors with one Arduino?
A4: Yes, but you will need a separate driver module for each motor and sufficient digital pins on the Arduino.
