4. Instruccions de funcionament

Once the board is set up and firmware is loaded, you can begin operation:

• Encès: Connect the board to a power source. The OLED display should illuminate, showing information based on the loaded firmware (e.g., network status, messages for Meshtastic).
• Pantalla OLED: The 0.96 inch SSD1306 OLED display provides visual feedback. Its resolution is 128x64, and it uses an I2C interface (SDA-IO18, SCL-IO17).
• Comunicació sense fils: Utilize the integrated Wi-Fi and Bluetooth 5.0 for local network connectivity or device pairing. The LoRa module (SX1280 2.4G) enables long-range, low-power communication.
• Botons de reinici i arrencada: The board features a Reset button to restart the microcontroller and a Boot button, typically used for entering bootloader mode during firmware flashing.
• Interacció de programari: Interact with the board through its serial interface (via USB) or wirelessly, depending on the firmware's capabilities. For Meshtastic, a mobile application or web interface is commonly used.

5. Manteniment

Proper maintenance ensures the longevity and reliable operation of your development board:

• Mantenir sec: Protect the board from moisture and humidity.
• Netegeu suaument: Use a soft, dry brush or compressed air to remove dust. Avoid liquid cleaners.
• Actualitzacions de firmware: Regularly check the official LILYGO GitHub repository (github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series) for firmware updates and security patches.
• Cura de l'antena: Ensure the antenna is securely connected but do not overtighten. Avoid bending or damaging the antenna.
