3. Configuració

To begin using your LILYGO T-Internet-POE board, follow these setup steps:

  1. Connect the Downloader Module: The T-Internet-POE board requires the included downloader expansion board for programming. Carefully align and connect the downloader module to the main board's dedicated programming header.
  2. Font d'alimentació: The board can be powered via the USB-C port on the downloader module or through Power over Ethernet (PoE) via the Ethernet port. Ensure your power source meets the specified voltage requirements (2.7V ~ 10.1V for PoE PD).
  3. Instal·lació del controlador: If connecting to a computer for programming, you may need to install the appropriate USB-to-serial drivers (e.g., CH340C) for your operating system.
  4. Development Environment Setup: For programming the ESP32, set up your preferred development environment, such as Arduino IDE or ESP-IDF. Refer to the official LILYGO GitHub repository for detailed setup guides and exampel codi: github.com/Xinyuan-LilyGO/LilyGO-T-ETH-POE.

4. Instruccions de funcionament

Once set up, the LILYGO T-Internet-POE board can be operated for various applications:

  • Programació: Use the connected downloader module and your development environment to upload firmware to the ESP32. The module provides a USB serial console for communication during development.
  • Connectivitat Ethernet: Connect an Ethernet cable to the RJ45 port. The LAN8720A chip handles the physical layer communication, allowing your ESP32 application to utilize wired network access.
  • Wi-Fi i Bluetooth: The ESP32-WROOM module supports 802.11n Wi-Fi and BLE V4.2, enabling wireless communication for your projects.
  • Ús de GPIO: Utilize the available GPIO pins for connecting sensors, actuators, and other peripheral components. Refer to the pinout diagram (Figure 2.5) for specific pin functions.
  • Suport de targeta TF: The board includes a TF card slot for external storage, useful for data logging or storing larger files.

5. Manteniment

Proper handling and maintenance will ensure the longevity of your LILYGO T-Internet-POE board:

  • Protecció contra descàrregues electrostàtiques (ESD): Electronic components are sensitive to ESD. Always handle the board by its edges and use anti-static precautions (e.g., an ESD wrist strap) when working with it.
  • Do Not Remove Yellow Sticker: There is a yellow reminder sticker on the board. Do not remove this sticker. It is present to protect the underlying chip from static electricity and potential damage if touched directly, especially when the board is powered.
  • Neteja: Keep the board free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning. Avoid using liquids.
  • Emmagatzematge: Store the board in an anti-static bag in a dry, cool environment when not in use.

6. Solució De Problemes

If you encounter issues with your LILYGO T-Internet-POE board, consider the following:

  • Errors de programació: Ensure the downloader module is correctly attached and that the correct COM port and board settings are selected in your IDE. Verify USB-to-serial drivers are installed.
  • Sense energia: Check USB-C cable connection or PoE source. Ensure the power supply meets the board's requirements.
  • Ethernet no funciona: Verify the Ethernet cable connection. Check your network configuration in the ESP32 firmware. Ensure your PoE injector/switch is providing power correctly if using PoE.
  • La junta no respon: Try pressing the RST (Reset) button. If issues persist, re-flash the firmware.
  • Static Discharge Damage: If the board was handled without ESD precautions, internal components might be damaged. This is often irreversible.
