TowerPro Metal Gear MG90S Mini Digital Servo Motor (180° Rotation)

Description

[Servo Motor] ⚙️ TowerPro MG90S Mini Digital Metal Gear Servo Motor (180°) Metal Gear Digital Servo 180° Rotation High Precision

🔹 Key Features

• •The standard 3-wire JR/Futaba-compatible connector allows direct interfacing with Arduino, ESP32, Raspberry Pi, STM32, and most RC receivers
• •For stable operation, use an external regulated power supply when driving the servo from microcontrollers
• •Product appearance, cable color, or accessories may vary slightly depending on the manufacturing batch
• •Counterfeit MG90S servos are common in the market
• •Purchase from trusted suppliers for genuine performance.

🔹 Technical Specifications

🔹 Pin Configuration & Wiring

// Safe Motor & Air Pump PWM Speed Control using L298N Driver
// Tested for Arduino Uno & ESP32 (with ESP32 ledcWrite)

#define ENA_PIN 9   // Connect to L298N ENA (PWM speed control)
#define IN1_PIN 8   // Connect to L298N IN1 (Direction / ON)
#define IN2_PIN 7   // Connect to L298N IN2 (Direction / OFF)

void setup() {
  pinMode(ENA_PIN, OUTPUT);
  pinMode(IN1_PIN, OUTPUT);
  pinMode(IN2_PIN, OUTPUT);
  
  // Initialize driver in OFF state
  digitalWrite(IN1_PIN, LOW);
  digitalWrite(IN2_PIN, LOW);
  analogWrite(ENA_PIN, 0);
}

void loop() {
  // Soft start: ramp up speed to prevent inrush current spikes
  digitalWrite(IN1_PIN, HIGH);
  digitalWrite(IN2_PIN, LOW);
  
  for (int speed = 100; speed <= 255; speed += 15) {
    analogWrite(ENA_PIN, speed);
    delay(50);
  }
  
  delay(3000); // Run motor at full speed for 3 seconds
  
  // Coast to stop
  digitalWrite(IN1_PIN, LOW);
  digitalWrite(IN2_PIN, LOW);
  analogWrite(ENA_PIN, 0);
  
  delay(2000); // Pause for 2 seconds
}

🔹 Applications

This component is engineered and suitable for:

• •⭐ Features Genuine TowerPro MG90S digital servo Durable all-metal gear transmission Approximate 180° rotation angle High positioning accuracy Fast control response High holding torque Smooth and quiet operation Lightweight and compact design Standard 3-wire servo interface Compatible with Arduino, ESP32, Raspberry Pi and RC receivers Ideal for robotics, RC models and automation projects

🔹 Package Includes

• ✓⚠️ Note Operate the servo only within the recommended 4.8V–6.0V DC supply range. For stable operation, use an external regulated power supply when driving the servo from microcontrollers. Product appearance, cable color, or accessories may vary slightly depending on the manufacturing batch. Counterfeit MG90S servos are common in the market. Purchase from trusted suppliers for genuine performance.
