1. Powering the Module: Connect the ESP32 Type-C to a 5V power source via the USB Type-C port. Alternatively, you can power it through the VIN pin with a regulated 5V supply.
2. Programming: Use the USB Type-C connection to upload code to the ESP32 using the Arduino IDE or other compatible development environments.
3. Connecting Peripherals: Use the GPIO pins to interface with sensors, actuators, and other peripherals. Ensure that the voltage levels are compatible (3.3V logic).
4. Wi-Fi and Bluetooth Setup: Configure the Wi-Fi and Bluetooth settings in your code to enable wireless communication.

• Always use a level shifter when interfacing 5V devices with the ESP32's 3.3V GPIO pins to prevent damage.
• Avoid drawing excessive current from the 3V3 pin, as it is limited by the onboard voltage regulator.
• Use decoupling capacitors near the power pins to reduce noise and improve stability.
• When using ADC pins, ensure the input voltage does not exceed 3.3V to avoid damaging the module.

Below is an example of using the ESP32 Type-C to connect to a Wi-Fi network and control an LED:

#include <WiFi.h> // Include the Wi-Fi library

// Replace with your network credentials
const char* ssid = "Your_SSID";
const char* password = "Your_PASSWORD";

const int ledPin = 2; // GPIO2 is connected to the onboard LED

void setup() {
  pinMode(ledPin, OUTPUT); // Set the LED pin as an output
  Serial.begin(115200);    // Initialize serial communication

  // Connect to Wi-Fi
  Serial.print("Connecting to Wi-Fi");
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("\nWi-Fi connected!");
  Serial.print("IP Address: ");
  Serial.println(WiFi.localIP());
}

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

1. ESP32 Not Detected by Computer:

   • Ensure the USB Type-C cable supports data transfer (not just charging).
   • Check if the correct COM port is selected in the Arduino IDE.
   • Install the necessary USB drivers for the ESP32.

2. Wi-Fi Connection Fails:

   • Double-check the SSID and password in your code.
   • Ensure the Wi-Fi network is within range and not overloaded.

3. GPIO Pins Not Responding:

   • Verify that the pins are not being used for other functions (e.g., boot mode).
   • Check for short circuits or incorrect wiring.

4. Module Overheating:

   • Ensure the input voltage does not exceed 5V.
   • Avoid drawing excessive current from the GPIO pins.

• Q: Can I power the ESP32 Type-C with a battery?
  A: Yes, you can use a 3.7V LiPo battery connected to the 3V3 pin or a 5V source connected to the VIN pin.

• Q: How do I reset the ESP32?
  A: Press the onboard reset button or pull the EN pin low momentarily.

• Q: Can the ESP32 Type-C handle 5V logic on GPIO pins?
  A: No, the GPIO pins are 3.3V logic. Use a level shifter for 5V devices.

• Q: Is the ESP32 Type-C compatible with Arduino libraries?
  A: Yes, the ESP32 is supported by the Arduino IDE and many libraries are available for it.
