It is ideal for developers looking to create connected devices with low power consumption and high performance.

• Smart home devices (e.g., smart lights, thermostats)
• Industrial IoT (IIoT) applications
• Wearable technology
• Wireless sensor networks
• Prototyping for Zigbee or Thread-based systems
• Low-power Bluetooth applications

The following table outlines the key technical specifications of the ESP32-C6-DEV-KIT-NX:

The ESP32-C6-DEV-KIT-NX features a 2-row pin header layout. Below is the pin configuration:

Note: For a complete pinout diagram, refer to the official Waveshare documentation.

1. Powering the Board:

   • Connect the board to your computer or a power source using a USB Type-C cable.
   • Alternatively, supply 5 V to the VIN pin and connect GND to the ground.

2. Programming the Board:

   • Install the latest version of the Arduino IDE or ESP-IDF (Espressif IoT Development Framework).
   • Add the ESP32-C6 board support package to your development environment.
   • Connect the board to your computer and select the appropriate COM port.

3. Connecting Peripherals:

   • Use the GPIO pins to connect sensors, actuators, or other peripherals.
   • Ensure that the voltage levels of connected devices are compatible with the 3.3 V logic of the ESP32-C6.

4. Uploading Code:

   • Write your code in the Arduino IDE or ESP-IDF.
   • Compile and upload the code to the board via the USB connection.

• Voltage Levels: Avoid applying voltages higher than 3.3 V to the GPIO pins to prevent damage.
• Boot Mode: To enter bootloader mode, hold the BOOT button while pressing the RESET button.
• Power Supply: Use a stable power source to ensure reliable operation, especially when using Wi-Fi or Bluetooth.

Below is an example of how to blink an LED connected to GPIO2:

// Define the GPIO pin for the LED
#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
}

Tip: Ensure that the LED is connected to GPIO2 with a current-limiting resistor (e.g., 220 Ω).

1. The board is not detected by the computer:

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

2. Code upload fails:

   • Check that the correct COM port is selected in the development environment.
   • Ensure the board is in bootloader mode by holding the BOOT button during upload.

3. Wi-Fi or Bluetooth is not working:

   • Verify that the correct libraries and configurations are included in your code.
   • Check for interference or weak signal strength in your environment.

4. The board overheats:

   • Ensure that the power supply voltage does not exceed the recommended range.
   • Avoid short circuits on the GPIO pins.
