• Small-scale mechatronics systems
• Educational and prototyping purposes

The following table outlines the key technical details of the GOTECK 5g Mini Servo:

The GOTECK 5g Mini Servo has a standard 3-pin connector. The pinout is as follows:

1. Power Connection: Connect the red wire to a 5V or 6V power source, depending on your desired torque and speed. Ensure the power supply can provide sufficient current (at least 500mA per servo).
2. Ground Connection: Connect the brown wire to the ground (GND) of your circuit.
3. Signal Connection: Connect the orange wire to the PWM output pin of your microcontroller (e.g., Arduino, Raspberry Pi).

• Power Supply: Use a stable power source to avoid voltage drops, which can cause erratic servo behavior.
• PWM Signal: Ensure the PWM signal is within the specified range (500 µs to 2500 µs) to avoid damaging the servo.
• Mechanical Load: Avoid overloading the servo beyond its torque rating to prevent overheating or gear damage.
• Mounting: Secure the servo properly to minimize vibrations and ensure accurate motion.

Below is an example of how to control the GOTECK 5g Mini Servo using an Arduino UNO:

#include <Servo.h> // Include the Servo library

Servo myServo; // Create a Servo object

void setup() {
  myServo.attach(9); // Attach the servo to pin 9 on the Arduino
}

void loop() {
  myServo.write(0); // Move the servo to 0 degrees
  delay(1000);      // Wait for 1 second

  myServo.write(90); // Move the servo to 90 degrees
  delay(1000);       // Wait for 1 second

  myServo.write(180); // Move the servo to 180 degrees
  delay(1000);        // Wait for 1 second
}

• The Servo library is included with the Arduino IDE by default.
• Adjust the delay values or angles as needed for your application.

1. Servo Not Moving:

   • Cause: Incorrect wiring or insufficient power supply.
   • Solution: Double-check the connections and ensure the power supply meets the voltage and current requirements.

2. Erratic or Jittery Movement:

   • Cause: Noise in the PWM signal or unstable power supply.
   • Solution: Use a decoupling capacitor (e.g., 100 µF) across the power and ground lines to stabilize the voltage.

3. Overheating:

   • Cause: Excessive mechanical load or prolonged operation at high torque.
   • Solution: Reduce the load on the servo or allow it to cool down periodically.

4. Limited Range of Motion:

   • Cause: PWM signal out of range or mechanical obstruction.
   • Solution: Ensure the PWM signal is within the 500 µs to 2500 µs range and check for physical obstructions.

Q: Can I use this servo with a 3.3V microcontroller?
A: Yes, but you must provide a separate 5V or 6V power source for the servo. Connect the ground of the microcontroller and the servo power supply together.

Q: What is the maximum current draw of this servo?
A: The maximum current draw is approximately 500mA under stall conditions. Ensure your power supply can handle this.

Q: Can I control multiple servos with one Arduino?
A: Yes, you can control multiple servos using different PWM pins. However, ensure your power supply can handle the combined current draw of all servos.

Q: Is this servo waterproof?
A: No, the GOTECK 5g Mini Servo is not waterproof. Avoid exposing it to water or moisture.
