Refer to the following pinout diagram for detailed information on the board's GPIOs and interfaces.

5. Funcionament

5.1. Programming the Board

The T3S3 V1.0 board can be programmed using the Arduino-IDE or Micropython. Connect the board to your computer via the Type-C USB port. You will need to install the appropriate board support packages and libraries for ESP32-S3 and LoRa communication in your chosen development environment.

5.2. LoRa Module Power Control (SX1280 PA Module)

⚠️ IMPORTANT WARNING: When using the SX1280 PA module, it is crucial to control the output power of the SX1280 chip between 2-5 dBm to ensure the entire module outputs a power of 20 dBm.

• If the output power of the SX1280 chip is set higher than 5 dBm, it will exceed the maximum allowable input for the FEM chip and can cause permanent damage to the module.
• If the output power is lower than 2 dBm, the module's output power will still be within 20 dBm, but may not be optimal.
• Recomanació: Setting the output power to 3 dBm will ensure an optimal output power of 20 dBm without risking damage.

5.3. Onboard OLED Display

The 0.96-inch OLED display (SSD1306 driver, I2C interface on IO18/IO17) can be used to display sensor data, status information, or debug messages. Libraries for SSD1306 are widely available for both Arduino and Micropython environments.

5.4. Reset and Boot Buttons

• Botó de restabliment: Press to restart the ESP32-S3 microcontroller.
• Botó d'arrencada: Used in conjunction with the Reset button to enter programming mode (bootloader). Typically, hold down the Boot button, press and release Reset, then release Boot.

6. Manteniment

• Manejar amb cura: Avoid dropping the board or subjecting it to excessive force.
• Electricitat estàtica: Electronic components are sensitive to static discharge. Handle the board on an anti-static mat or by touching a grounded object first.
• 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 a dry, cool environment, preferably in an anti-static bag when not in use.

7. Solució De Problemes

• La placa no s'encén: Ensure the Type-C USB cable is properly connected to a power source or that the Lipo battery is charged and the battery switch is 'ON'.
• Unable to Upload Code: Verify that the correct board (ESP32-S3 Dev Module) and COM port are selected in your IDE. Ensure the necessary drivers are installed. Try entering bootloader mode manually (hold Boot, press/release Reset, then release Boot).
• Problemes de comunicació de LoRa: Check antenna connection. Verify LoRa module power settings, especially for SX1280 (refer to Section 5.2). Ensure frequency bands match between communicating devices.
• La pantalla OLED no funciona: Check I2C connections (IO18/IO17). Ensure the correct SSD1306 library is installed and initialized in your code.
• Module Damage after LoRa Use: If using the SX1280 PA module, re-check your code for the SX1280 chip's output power setting. Values above 5 dBm can damage the FEM chip.

8. Consells d'usuari

• Optimize LoRa Range: For maximum LoRa communication range, ensure your antenna is properly connected and positioned. Experiment with different LoRa spreading factors and bandwidths to find the optimal settings for your environment.
• Gestió d'energia: When running on battery, optimize your code for low power consumption by utilizing ESP32-S3's deep sleep modes and only activating peripherals when necessary.
• Suport comunitari: LILYGO products often have active communities. Search online forums and groups for project ideas, code examples, and troubleshooting advice from other users.
