3. Asennusohjeet

Follow these steps to set up your LILYGO T3S3 development board:

1. Kiinnitä antenni: Kierrä toimitettu LoRa-antenni varovasti piirilevyn SMA-liittimeen. Varmista, että se on sormin kiristetty vaurioiden välttämiseksi.
2. Virtaliitäntä: Connect the board to a power source using the USB Type-C port. Alternatively, use the provided power cable for a 3.7V LiPo battery connection. The board supports USB/3.7V LiPo battery power supply.
3. Initial Firmware: The board may come with pre-installed firmware (e.g., Meshtastic). To install or update firmware, refer to the official LILYGO Wiki or GitHub repository for detailed instructions and tools. A common method involves using the ESP-IDF or Arduino IDE.
4. TF-kortin asettaminen (valinnainen): If your application requires external storage, insert a compatible TF card into the designated slot on the board.
5. Pin Headers (Optional): Attach the included pin headers if you plan to integrate the board into a breadboard or custom circuit. Refer to the pinout diagram for correct connections.

4. Käyttöohjeet

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

• Virta päälle: 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).
• OLED-näyttö: The 0.96 inch SSD1306 OLED display provides visual feedback. Its resolution is 128x64, and it uses an I2C interface (SDA-IO18, SCL-IO17).
• Langaton viestintä: 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.
• Nollaus- ja käynnistyspainikkeet: The board features a Reset button to restart the microcontroller and a Boot button, typically used for entering bootloader mode during firmware flashing.
• Ohjelmiston vuorovaikutus: 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. Huolto

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

• Pidä kuivana: Suojaa levy kosteudelta ja ilmankosteudelta.
• Puhdista hellävaraisesti: Use a soft, dry brush or compressed air to remove dust. Avoid liquid cleaners.
• Laiteohjelmistopäivitykset: Regularly check the official LILYGO GitHub repository (github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series) for firmware updates and security patches.
• Antennihoito: Ensure the antenna is securely connected but do not overtighten. Avoid bending or damaging the antenna.

6. Vianmääritys

Jos kohtaat ongelmia LILYGO T3S3 -korttisi kanssa, ota huomioon seuraavat seikat:

• Levy ei käynnisty:
  • Verify the USB cable is properly connected to a working power source.
  • If using a LiPo battery, ensure it is charged and correctly connected to the battery switch.
• OLED Display Blank:
  • Tarkista virtalähde.
  • Ensure firmware is correctly loaded and configured to initialize the OLED.
• No Wireless Connectivity (Wi-Fi/Bluetooth/LoRa):
  • Confirm the antenna is attached correctly for LoRa.
  • Verify that the firmware includes the necessary drivers and configurations for the wireless modules.
  • Tarkista paikalliset häiriöt.
• Laiteohjelmiston latausongelmat:
  • Ensure correct drivers for the USB-to-serial chip are installed on your computer.
  • Paina ja pidä painettuna Boot -painiketta samalla painettuna ja vapauta seasing Nollaa button, then release Boot to enter flashing mode.
  • Consult the LILYGO Wiki (wiki.lilygo.cc) or GitHub for specific flashing instructions for your operating system and development environment.
