How to Use Driver: Examples, Pinouts, and Specs

The WAVGAT Driver Module is an electronic component designed to control and regulate power to other components within a circuit. It is commonly used in applications that require precise control over the operation of motors, LEDs, and other high-power devices. The driver module ensures that these components receive the correct amount of power for optimal performance, while also providing protection against overcurrent and overheating.

• Motor control in robotics and automation systems
• LED dimming and control in lighting systems
• Power regulation for sensitive electronic circuits

• Input Voltage Range: 3.3V to 5V
• Output Current: Up to 2A (peak)
• Operating Temperature: -40°C to +85°C

1. Power Supply Connection: Connect the Vcc pin to a suitable power supply within the specified voltage range. Ensure that the power supply can deliver sufficient current for the load.
2. Ground Connection: Connect the GND pin to the ground of your power supply and the ground of the control circuit (e.g., Arduino UNO).
3. Input Signal: Connect the IN pin to a control signal source, such as a PWM output from a microcontroller.
4. Output Connection: Connect the OUT pin to the component you wish to drive, such as a motor or LED.

• Always verify that the power supply voltage and current capabilities are within the specifications of the driver module.
• Use a flyback diode when driving inductive loads like motors to prevent voltage spikes.
• Ensure adequate heat dissipation for the driver module when operating at high currents.
• Avoid running the driver at its maximum ratings for extended periods to prolong its lifespan.

// Example code to control a motor with the WAVGAT Driver Module
#define DRIVER_IN_PIN 3 // Connect to the IN pin of the driver

void setup() {
  pinMode(DRIVER_IN_PIN, OUTPUT);
}

void loop() {
  // Spin the motor at full speed for 2 seconds
  analogWrite(DRIVER_IN_PIN, 255); // Send a full-speed PWM signal
  delay(2000);
  
  // Stop the motor for 2 seconds
  analogWrite(DRIVER_IN_PIN, 0); // Send a zero-speed PWM signal
  delay(2000);
  
  // Spin the motor at half speed for 2 seconds
  analogWrite(DRIVER_IN_PIN, 127); // Send a half-speed PWM signal
  delay(2000);
}

• Motor not spinning: Ensure that the power supply is correctly connected and that the input signal is being sent from the microcontroller.
• Overheating: If the driver module is overheating, check if the current draw is within the specified limit and improve heat dissipation.
• Inconsistent operation: Verify that all connections are secure and that there is no interference with the input signal.

• Double-check wiring and solder joints for any loose connections or shorts.
• Use a multimeter to measure the voltage at the Vcc and GND pins to ensure proper power supply.
• If using PWM, verify the frequency and duty cycle are within the driver's operating range.

Q: Can I use this driver module with a 3.3V microcontroller? A: Yes, the driver module can operate with a 3.3V input signal.

Q: What is the maximum frequency for the PWM input signal? A: The maximum recommended frequency for the PWM input signal is 100kHz.

Q: How can I increase the current handling capability of the driver? A: To handle higher currents, consider using a heatsink or a fan for cooling, or use multiple drivers in parallel, ensuring that the load is evenly distributed.
