- This warehouse currently only maintains the version of LilyGo that is on sale , For the LilyGo discontinued version of the LoRa board, please jump to [Archive package](https://github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/releases/tag/v0.0.1) to download
- Arduino IDE users need to configure the board to be used in the <utilities.h> file in the sketch directory before using the example. The <utilities.h> file contains the pin definitions of the board. If you do not select it, an error will occur during compilation.

## 4️⃣ PlatformIO Quick Start (Recommended)
Update README
2024-12-30 17:19:30 +08:00
1. For users using the ESP32 version (non ESP32S3 version), please install the **CH9102 USB bridge** driver for the first time.
- [Windows](https://www.wch-ic.com/downloads/CH343SER_ZIP.html)
- [Mac OS](https://www.wch-ic.com/downloads/CH34XSER_MAC_ZIP.html)
2. Install [Visual Studio Code](https://code.visualstudio.com/) and [Python](https://www.python.org/)
3. Search for the `PlatformIO` plugin in the `VisualStudioCode` extension and install it.
4. After the installation is complete, you need to restart `VisualStudioCode`
5. After restarting `VisualStudioCode`, select `File` in the upper left corner of `VisualStudioCode` -> `Open Folder` -> select the `LilyGo-LoRa-Series` directory
6. Wait for the installation of third-party dependent libraries to complete
7. Click on the `platformio.ini` file, and in the `platformio` column
8. Select the board name you want to use in `default_envs` and uncomment it.
9. Uncomment one of the lines `src_dir = xxxx` to make sure only one line works , Please note the example comments, indicating what works and what does not.
10. Click the (✔) symbol in the lower left corner to compile
11. Connect the board to the computer USB-C , Micro-USB is used for module firmware upgrade
12. Click (→) to upload firmware
13. Click (plug symbol) to monitor serial output
14. If it cannot be written, or the USB device keeps flashing, please check the **FAQ** below

1. T-Beam Supreme GPS backup power comes from 18650 battery. If you remove the 18650 battery, you will not be able to get GPS hot start. If you need to use GPS hot start, please connect the 18650 battery.

Serial.println(F("Selected output power is invalid for this module!"));
while (true);
}
// set over current protection limit to 80 mA (accepted range is 45 - 240 mA)

- When using the SX1280 PA module, it is recommended that the software controls the 1280 chip to output 2~5dbm, so that the entire module will output 20dbm power;
When the output of the 1280 chip is higher than 2dbm, the output power of the entire module is only 20dbm;
When the output of the 1280 chip is higher than 5dbm, the output power of the entire module is only 20dbm, but if 5dbm is given to the FEM, it will damage the FEM chip (the maximum input allowed by the FEM is 5dbm)
If the output of the 1280 chip is lower than 2dbm, the output power of the entire module is within 20dbm.
- T3-S3 PA version SX1280 output power setting cannot be greater than 2~5dbm, otherwise the FEM chip may be damaged. Setting 3dbm already has 20dmb output power

- To identify the LoRa model, you only need to check the sticker on the board. 433MHz is SX1278, 868MHz is SX1276, and if the label says SX1262, it is SX1262.

10. T3-S3 Qwiic GPIO10, GPIO21 cannot be used?

</summary>
- If you are using the SX1280/SX1280PA version, these two GPIOs are already connected to the Radio TX/RX Pin and cannot be used.
- If you are using the SX1262/SX1276 version, you can use GPIO10,21 by removing the two resistors in the figure below. Otherwise, the GPIO is connected to Radio DIO3,DIO4 by default.
