    • To upload a sketch, you need to hold down the BOOT button on the board and then plug in the USB. At this time, it will enter the DFU mode to allow program writing.

  6. Please uncomment the utilities.h file of each sketch according to your board model, otherwise the compilation will report an error.

7️⃣ FAQ

  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.

  2. There is no data output from the GPS. Refer to GPS factory reset

  3. How to find the pin definition?

    Click to view detailed
    • Each sketch contains <utilities.h>, and all board pins are written in this file

  4. Can’t upload sketches?

    Click to view detailed
    1. Connect the board USB to the computer
    2. Press the BOOT button and hold (If there is no BOOT button, you need to keep GPIO0 connected to GND.)
    3. Press the RST button
    4. Release the RST button
    5. Finally release the BOOT button(If there is no BOOT button, you need to disconnect GPIO0 from GND.)
    6. Click to upload the program

  5. After setting the output power of LoRa, you need to set the minimum current. Set up sx1262 as follows:

    Click to view detailed 
    // set output power to 10 dBm (accepted range is -17 - 22 dBm)
if (radio.setOutputPower(22) == RADIOLIB_ERR_INVALID_OUTPUT_POWER) {
    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)
// NOTE: set value to 0 to disable overcurrent protection
if (radio.setCurrentLimit(80) == RADIOLIB_ERR_INVALID_CURRENT_LIMIT) {
    Serial.println(F("Selected current limit is invalid for this module!"));
    while (true);
}

  6. Precautions for using SX1280 PA version

    Click to view detailed
    • 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

  7. How to identify the LoRa model?

    Click to view detailed
    • 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.

  8. Why does Serial not have any output?

    • Arduino -> Tools -> USB CDC On Boot -> Enable
