9-60V 20A DC Motor Speed Controller Pinout and Connection Guide
The 9-60V 20A DC Motor Speed Controller is a versatile and high-performance motor driver designed to control the speed of DC motors within a wide voltage range. This document explains the pinout and connection guide for the controller, outlining each pin's function and how to connect them properly.
Pinout:
The controller has a total of 6 pins, each with a specific function. The pinout is as follows:
VIN (Positive Power Input)
GND (Ground)
PWMin (Pulse Width Modulation Input)
ENA (Enable Input)
OUT+ (Motor Positive Output)
OUT- (Motor Negative Output)
Pin Connection Guide:
1. VIN (Positive Power Input)
Connect to a DC power source (9-60V) positive terminal.
Make sure the power source can supply the required current for the motor.
2. GND (Ground)
Connect to the DC power source negative terminal.
Ensure a solid ground connection to prevent noise and interference.
3. PWMin (Pulse Width Modulation Input)
Connect to a microcontroller's PWM output pin (e.g., Arduino's digital pin 3, 5, 6, 9, 10, or 11).
This pin receives the PWM signal from the microcontroller, which controls the motor speed.
4. ENA (Enable Input)
Connect to a microcontroller's digital output pin (e.g., Arduino's digital pin 2, 4, 7, 8, 12, or 13).
This pin enables or disables the motor controller. A high logic level (VCC) enables the controller, while a low logic level (GND) disables it.
5. OUT+ (Motor Positive Output)
Connect to the positive terminal of the DC motor.
Ensure the motor's positive terminal is connected to this pin.
6. OUT- (Motor Negative Output)
Connect to the negative terminal of the DC motor.
Ensure the motor's negative terminal is connected to this pin.
Important Connection Notes:
Always ensure the power source voltage is within the controller's specified range (9-60V).
Use proper heat sinks and thermal management to prevent overheating.
Connect the motor to the OUT+ and OUT- pins, ensuring correct motor polarity.
Use a suitable current-limiting resistor or fuse to protect the motor and controller from excessive current.
By following this pinout and connection guide, you can successfully integrate the 9-60V 20A DC Motor Speed Controller into your project and control the speed of your DC motor with precision and reliability.

void setup() {
  pinMode(motorDirPin, OUTPUT);
  pinMode(motorSpeedPin, OUTPUT);
  pinMode(enablePin, OUTPUT);
  digitalWrite(enablePin, HIGH); // Enable the motor controller
}

void loop() {
  // Set motor direction to forward
  digitalWrite(motorDirPin, HIGH);
  
  // Set motor speed to 50% duty cycle
  analogWrite(motorSpeedPin, 128);
  
  delay(1000);
  
  // Set motor speed to 100% duty cycle
  analogWrite(motorSpeedPin, 255);
  
  delay(1000);
}

    while True:
        # Set motor direction to forward
        GPIO.output(motor_dir_pin, GPIO.HIGH)
        
        # Set motor speed to 50% duty cycle
        pwm = GPIO.PWM(motor_speed_pin, 1000)
        pwm.start(50)
        
        time.sleep(1)
        
        # Set motor speed to 100% duty cycle
        pwm.ChangeDutyCycle(100)
        
        time.sleep(1)
except KeyboardInterrupt:
    pass

GPIO.cleanup()
