Usage Instructions

How to Use the Firebeetle 2 Board ESP32-C6 in a Circuit

1. Powering the Board:

   • Connect the board to a computer or power source using a USB-C cable. The board operates at 3.3V internally but accepts 5V input via USB.

2. Programming the Board:

   • Install the Arduino IDE or ESP-IDF (Espressif IoT Development Framework).
   • Add the ESP32-C6 board support package to your development environment.
   • Select the correct board and port in the IDE settings.

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 3.3V logic of the board.

4. Uploading Code:

   • Write your code in the IDE and upload it to the board via the USB-C connection. The onboard bootloader simplifies the process.

Important Considerations and Best Practices

• Voltage Levels: Ensure all connected peripherals operate at 3.3V logic levels to avoid damaging the board.
• Power Management: Utilize the ultra-low power modes for battery-powered applications.
• Antenna Placement: Avoid placing the board near metal objects or enclosures that could interfere with wireless signals.
• Firmware Updates: Regularly update the ESP32-C6 firmware to access the latest features and security patches.

Example Code for Arduino UNO Integration

Below is an example of using the Firebeetle 2 Board ESP32-C6 to read data from a DHT11 temperature and humidity sensor and send it to a serial monitor:

#include <DHT.h>

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

DHT dht(DHTPIN, DHTTYPE);

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

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

  // Read temperature and humidity values
  float humidity = dht.readHumidity();
  float temperature = dht.readTemperature();

  // 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");
}
