The following table outlines the key technical details of the ESP32-C6-DEV-KIT-N8:

The ESP32-C6-DEV-KIT-N8 features a 22-pin GPIO layout. Below is the pin configuration:

1. Powering the Board: Connect the board to a computer or power source using a USB Type-C cable. Ensure the power supply provides 5V.
2. Programming the Board: Use the Arduino IDE or ESP-IDF (Espressif IoT Development Framework) to program the board. Install the necessary drivers and libraries for ESP32-C6.
3. Connecting Peripherals: Use the GPIO pins to connect sensors, actuators, or other peripherals. Refer to the pin configuration table for specific pin functions.
4. Uploading Code: Compile and upload your code to the board via the USB connection. Ensure the correct COM port and board type are selected in your development environment.

• Voltage Levels: The GPIO pins operate at 3.3V. Avoid applying higher voltages to prevent damage.
• Boot Mode: To enter bootloader mode, hold the IO0 pin low while resetting the board.
• Wi-Fi and Bluetooth Antenna: Ensure the onboard antenna is not obstructed for optimal wireless performance.
• Power Supply: Use a stable 5V power source to avoid unexpected resets or instability.

Below is an example of using the ESP32-C6-DEV-KIT-N8 to read data from a DHT11 temperature and humidity sensor and send it to a serial monitor:

#include <DHT.h>

// Define the DHT sensor pin and type
#define DHTPIN 4 // GPIO4 is connected to the DHT11 data pin
#define DHTTYPE DHT11

DHT dht(DHTPIN, DHTTYPE);

void setup() {
  Serial.begin(115200); // Initialize serial communication at 115200 baud
  dht.begin();          // Initialize the DHT sensor
  Serial.println("DHT11 Sensor Test");
}

void loop() {
  delay(2000); // Wait 2 seconds between readings

  float humidity = dht.readHumidity();    // Read humidity
  float temperature = dht.readTemperature(); // Read temperature in Celsius

  // Check if the readings are valid
  if (isnan(humidity) || isnan(temperature)) {
    Serial.println("Failed to read from DHT sensor!");
    return;
  }

  // Print the readings to the serial monitor
  Serial.print("Humidity: ");
  Serial.print(humidity);
  Serial.print("%  Temperature: ");
  Serial.print(temperature);
  Serial.println("°C");
}

1. Board Not Detected by Computer:

   • Ensure the USB cable is functional and supports data transfer.
   • Install the correct USB-to-serial drivers for the ESP32-C6.

2. Code Upload Fails:

   • Verify the correct COM port and board type are selected in the IDE.
   • Check if the board is in bootloader mode (hold IO0 low during reset).

3. Wi-Fi or Bluetooth Connectivity Issues:

   • Ensure the onboard antenna is unobstructed.
   • Verify the network credentials or Bluetooth pairing settings in your code.

4. Unstable Operation:

   • Use a stable 5V power source.
   • Avoid exceeding the GPIO voltage limits (3.3V).

• Reset the Board: Press the reset button to restart the board and clear temporary issues.
• Check Connections: Ensure all peripheral connections are secure and correctly wired.
• Update Firmware: Use the latest ESP-IDF or Arduino core for ESP32 to ensure compatibility and bug fixes.
• Debugging: Use the serial monitor to print debug messages and identify issues in your code.
