Guide Setup
1. Nyambungkeun Antenna

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. Powering Modul
The LILYGO TTGO T3S3 module offers two primary power supply methods:
- USB Power: 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).
Parentah Operasi
1. Pangembangan Lingkungan Setup
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.
Catetan: 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. Pamakéan Kartu TF
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.
Pangropéa
- Tetep garing: Protect the module from moisture and liquids to prevent short circuits and corrosion.
- Nanganan kalayan ati-ati: Avoid dropping or subjecting the module to strong impacts.
- Kabersihan: Keep the board free from dust and debris. Use a soft, dry brush or compressed air for cleaning.
- Integritas sambungan: Periodically check all connections, especially the antenna and pin headers, to ensure they are secure.
- Panyimpenan: When not in use, store the module in an anti-static bag or a protective enclosure to prevent electrostatic discharge damage.
Pamérésan masalah
