Guia de configuració

1. Connexió de l'antena

Before powering on the module, it is crucial to connect the provided 2.4G antenna to the IPEX/U.FL connector on the board. Ensure the connection is secure to prevent damage to the LoRa transceiver and to ensure optimal wireless performance. The antenna typically screws onto a small gold-colored connector on the board, as shown in the image.

2. Alimentació del mòdul

The LILYGO TTGO T3S3 module offers two primary power supply methods:

• Potència USB: Connect a standard USB-C cable to the USB port on the module and to a 5V power source (e.g., computer USB port, USB wall adapter). This method is commonly used for programming and initial testing.
• Lipo Battery Power: For portable applications, connect a 3.7V Lipo battery to the dedicated battery connector. Ensure correct polarity. The module includes a battery switch to control power when using a Lipo battery.

Always ensure the power source matches the module's requirements (5V via USB, 3.7V via Lipo) to prevent damage.

3. Initial Connection to Computer

To program the module, connect it to your computer using a USB-C cable. Your operating system should recognize the device and install necessary drivers. If drivers are not automatically installed, you may need to manually install the appropriate USB-to-serial drivers (e.g., CP210x or CH340, depending on the specific board revision).

Instruccions de funcionament

1. Configuració de l'entorn de desenvolupament

The LILYGO TTGO T3S3 module is compatible with popular ESP32 development environments such as the Arduino IDE and PlatformIO. You will need to install the ESP32 board support package for your chosen IDE. Refer to the official Espressif documentation or LILYGO's GitHub repository for detailed instructions on setting up your development environment.

2. Programming and Uploading Firmware

Once your development environment is set up, you can write and upload your code (firmware) to the module. The module features a Reset button and a Boot button. To enter bootloader mode for flashing new firmware, typically you would hold down the Boot button, press and release the Reset button, then release the Boot button. Consult your specific IDE's documentation for the exact upload procedure.

The 0.96-inch OLED display can be used to show status, sensor readings, or other information from your program. The image highlights the display and the location of the Boot button.

3. Using LoRa, WiFi, and Bluetooth

The ESP32-S3 chip provides robust support for Wi-Fi and Bluetooth 5.0. The integrated SX1280 chip enables 2.4G LoRa communication. Libraries and examples for these functionalities are widely available within the ESP-IDF framework and Arduino ESP32 core. For LoRa, ensure your antenna is correctly connected and configured for the 2.4G frequency band.

Nota: This module is known to be compatible with projects like Meshtastic, which leverages LoRa for off-grid communication. Refer to the Meshtastic project documentation for specific setup and usage instructions if you plan to use it for this purpose.

4. TF Card Usage

The module includes a TF (MicroSD) card slot, allowing you to store data, logs, or configuration files directly on the board. Standard SD card libraries can be used in your firmware to interact with the card.

Manteniment

• Mantenir sec: Protect the module from moisture and liquids to prevent short circuits and corrosion.
• Manejar amb cura: Avoid dropping or subjecting the module to strong impacts.
• Neteja: Keep the board free from dust and debris. Use a soft, dry brush or compressed air for cleaning.
• Integritat de la connexió: Periodically check all connections, especially the antenna and pin headers, to ensure they are secure.
• Emmagatzematge: When not in use, store the module in an anti-static bag or a protective enclosure to prevent electrostatic discharge damage.

Resolució de problemes

• El mòdul no s'encén:
  • Ensure USB cable is securely connected and providing 5V.
  • If using Lipo battery, check battery charge and ensure the battery switch is in the 'ON' position.
• Computer Not Recognizing Module:
  • Try a different USB cable or USB port on your computer.
  • Install or update the necessary USB-to-serial drivers (e.g., CP210x, CH340).
• Error de càrrega de firmware:
  • Ensure the correct board and COM port are selected in your IDE.
  • Verify the module is in bootloader mode (hold Boot, press/release Reset, release Boot).
  • Check for any error messages in the IDE's output console.
• Wireless Communication Issues (LoRa/WiFi/Bluetooth):
  • Confirm the antenna is securely connected.
  • Verify your code correctly initializes and uses the wireless modules.
  • Check for environmental interference or range limitations.
• La pantalla OLED no funciona:
  • Ensure your code correctly initializes and sends data to the OLED display.
  • Check connections if the display is not directly soldered.
