5. Getting Started

5.1. Installation Steps

1. Install the development environment:
   Download and install the Arduino IDE. Add the development board support package to the Arduino IDE by adding an additional board URL in Preferences. Install the LoRa library (e.g., Arduino-LoRa).
2. Connect the device:
   Connect the development board to your computer using a USB cable. Select the development board model as 'Dev Module' and choose the correct serial port in the Arduino IDE.
3. Programming and Testing:
   Select example code (e.g., 'LoRa Send' or 'LoRa Receive') from the Arduino IDE. Configure the frequency to 868MHz or 915MHz, depending on regional specifications. Upload the code to the board and monitor the serial port output for testing.
4. OLED Display Use:
   Utilize the U8g2 or Adafruit_SSD1306 library to control the integrated 0.96-inch OLED display.
5. External Sensor Connection:
   Connect sensors via I2C, UART, or GPIO interfaces as required by your project.
