   • Alternatively, supply 7-12V to the VIN pin for standalone operation.

2. Programming the Board:

   • Install the Arduino IDE or any compatible programming environment.
   • Add the ESP32 board support package to your IDE.
   • Select "A01NYUB V2" or a compatible ESP32 board from the board manager.
   • Connect the board to your computer and upload your code.

3. Connecting Peripherals:

   • Use the GPIO pins to connect sensors, actuators, or other peripherals.
   • Ensure that the voltage and current requirements of your peripherals are compatible with the board.

Example Circuit

Below is an example of connecting an LED to GPIO2:

• Connect the positive leg of the LED to GPIO2 through a 220-ohm resistor.
• Connect the negative leg of the LED to GND.

Example Code

The following code demonstrates how to blink an LED connected to GPIO2:

// Define the GPIO pin where the LED is connected
#define LED_PIN 2

void setup() {
  // Set the LED pin as an output
  pinMode(LED_PIN, OUTPUT);
}

void loop() {
  // Turn the LED on
  digitalWrite(LED_PIN, HIGH);
  delay(1000); // Wait for 1 second

  // Turn the LED off
  digitalWrite(LED_PIN, LOW);
  delay(1000); // Wait for 1 second
}

Important Considerations

• Avoid exceeding the maximum voltage and current ratings of the board.
• Use level shifters when interfacing with 5V logic devices.
• Ensure proper grounding to avoid noise and instability in your circuit.
