3.3 Pradinis programinės įrangos įkėlimas
To begin using the T3-S3 MVSRBoard, you will need to upload firmware. Detailed instructions and example code can be found on the official LILYGO GitHub repository:
github.com/Xinyuan-LilyGO/T3-S3-MVSRBoard
Typically, this involves:
- Installing the Arduino IDE or PlatformIO.
- Adding ESP32 board support.
- Downloading the example code from the GitHub repository.
- Connecting the board via USB-C.
- Tinkamos plokštės ir prievado pasirinkimas IDE.
- Pressing the 'Boot' button (if required by your specific firmware upload process) while uploading.

4. Naudojimo instrukcijos
The operational aspects of the T3-S3 MVSRBoard are largely dependent on the firmware loaded onto it. The following provides general guidance:
4.1 LoRa Voice Communication
For LoRa-based voice transmission and reception, the firmware will manage the SX1262 module. Ensure your LoRa network parameters (frequency, spreading factor, coding rate, etc.) are correctly configured in your code to match the intended communication partners.
4.2 Speaker and Microphone Usage
The integrated speaker and microphone allow for audio input and output. Your firmware will need to interface with these components to capture audio via the microphone and play audio through the speaker. This is crucial for voice communication applications.

4.3 RTC Functionality
The Real-Time Clock (RTC) module provides accurate timekeeping. Firmware can be developed to read and set the time, enabling time-stamping data or scheduling events. The RTC typically requires a small coin cell battery (not always included) to maintain time when the main power is off.
4.4 Vibration Motor Activation
The vibration motor can be controlled via software to provide haptic feedback or alerts. This can be useful for notifications in applications where audible alerts are not suitable.
5. Priežiūra
Proper maintenance ensures the longevity and reliable operation of your LILYGO T3-S3 MVSRBoard.
- Valymas: Keep the board free from dust and debris. Use a soft, dry brush or compressed air for cleaning. Avoid using liquids directly on the board.
- Saugykla: Store the board in a dry, anti-static environment when not in use. The original packaging or an anti-static bag is recommended.
- Tvarkymas: Always handle the board by its edges to avoid touching sensitive components. Static electricity can damage electronic components, so use anti-static precautions (e.g., a grounded wrist strap) when handling.
- Aplinkos sąlygos: Avoid exposing the board to extreme temperatures, high humidity, or direct sunlight.
6. Problemų sprendimas
If you encounter issues with your T3-S3 MVSRBoard, consider the following troubleshooting steps:
- Nėra maitinimo / šviesos diodai išjungti: Įsitikinkite, kad USB-C laidas yra tvirtai prijungtas prie veikiančio maitinimo šaltinio. Išbandykite kitą USB-C laidą arba maitinimo adapterį.
- Nepavyko įkelti programinės įrangos: Verify that the correct board and COM port are selected in your development environment. Ensure all necessary drivers are installed. Try pressing and holding the 'Boot' button while initiating the upload, then releasing it.
- LoRa komunikacijos problemos: Check that the antenna is properly attached. Verify that both transmitting and receiving devices are configured with matching LoRa parameters (frequency, spreading factor, etc.). Ensure there are no major obstructions between devices.
- Audio Problems (Speaker/Mic): Confirm that the speaker and microphone are correctly connected (if detachable) and that your firmware is properly initializing and controlling them. Check volume settings in your code.
- Su programine įranga susijusios problemos: Refer to the official GitHub repository for common issues, community discussions, and updated code examples.
