MG90S Mini Servo Motor (180 Degree) Pinout and Connection Guide
The MG90S Mini Servo Motor is a compact and lightweight servo motor designed for various IoT and robotics applications. It has a maximum rotation angle of 180 degrees and is widely used in robotic arms, grippers, and other mechanisms that require precise angular movement. Here's a detailed explanation of the pins and their connections:
Pin Structure:
The MG90S Mini Servo Motor has a 3-pin male JST connector. The pins are labeled as follows:
Pin 1: VCC (Red Wire)
Function: Power Supply (Positive)
Description: This pin should be connected to a stable power supply, typically between 4.8V to 6V. The recommended voltage is 5V.
Connection: Connect to the positive terminal of your power source (e.g., battery or voltage regulator output).
Pin 2: GND (Brown Wire)
Function: Ground
Description: This pin should be connected to the ground terminal of your power source.
Connection: Connect to the negative terminal of your power source (e.g., battery or voltage regulator ground).
Pin 3: SIG (Orange Wire)
Function: Signal Input
Description: This pin receives the control signal from your microcontroller or servo controller. The signal is typically a PWM (Pulse Width Modulation) signal.
Connection: Connect to the corresponding servo signal pin on your microcontroller or servo controller.
Connection Example:
Here's an example of how to connect the MG90S Mini Servo Motor to an Arduino Uno board:
Connect the VCC (Red Wire) pin to the 5V pin on the Arduino Uno board.
Connect the GND (Brown Wire) pin to the GND pin on the Arduino Uno board.
Connect the SIG (Orange Wire) pin to any available digital pin on the Arduino Uno board (e.g., Digital Pin 9).
Important Notes:
Make sure to use a stable power supply to avoid damage to the servo motor.
The servo motor should not be operated without a load or with excessive load, as this can cause damage to the motor.
When connecting the servo motor to a microcontroller or servo controller, ensure that the signal format and frequency are compatible with the servo motor's requirements.
By following these pinout and connection guidelines, you can successfully integrate the MG90S Mini Servo Motor into your IoT or robotics project.

Code Examples

### Example 1: Basic Servo Control with Arduino

This example demonstrates how to control the MG90S Mini Servo Motor using an Arduino board.
```c++
#include <Servo.h>

Servo myServo;  // create a servo object

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

void loop() {
  myServo.write(0);  // set the servo to 0 degrees
  delay(1000);
  myServo.write(90);  // set the servo to 90 degrees
  delay(1000);
  myServo.write(180);  // set the servo to 180 degrees
  delay(1000);
}
```
### Example 2: Sweep Control with Raspberry Pi (Python)

This example demonstrates how to control the MG90S Mini Servo Motor using a Raspberry Pi and Python.
```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)  # set up GPIO 18 as an output

pwm = GPIO.PWM(18, 50)  # create a PWM object with a frequency of 50 Hz
pwm.start(0)  # start the PWM with a duty cycle of 0

while True:
    for i in range(0, 181, 10):  # sweep the servo from 0 to 180 degrees
        pwm.ChangeDutyCycle(i / 18 + 2)  # calculate the duty cycle for the current angle
        time.sleep(0.1)
    time.sleep(1)
```
### Example 3: Servo Control with ESP32 (MicroPython)

This example demonstrates how to control the MG90S Mini Servo Motor using an ESP32 board and MicroPython.
```python
import machine
import time

servo = machine.PWM(machine.Pin(18), freq=50)  # create a PWM object with a frequency of 50 Hz

while True:
    for i in range(0, 180, 10):  # sweep the servo from 0 to 180 degrees
        servo.duty(i)  # set the duty cycle for the current angle
        time.sleep(0.1)
    time.sleep(1)
```
Note: Make sure to adjust the pin numbers and PWM frequencies according to your specific board and setup. Additionally, ensure that the power supply to the servo motor is within the recommended voltage range.
