T3-S3 – SX1276 868MHz

⚠️Cautions⚠️
When using the “SX1280 2.4G With PA [H658]“, it is recommended that the software control 1280 chip output 2 to 5 dbm, so that the entire module will output 20 dbm of power; When the output of the 1280 chip is higher than 2 dbm, the output power of the entire module is only 20 dbm; When the output of 1280 chip is higher than 5 dbm, the output power of the entire module is only 20 dbm, but if 5 dbm is given to the FEM, it will damage the FEM chip (the maximum allowable input for the FEM is 5 dbm) If the output of the 1280 chip is lower than 2 dbm, the output power of the entire module is within 20 dbm. The output power setting of the SX1280 cannot be greater than 2-5dbm, otherwise, damage to the FEM chip may occur. Set 3dBM to have an output power of 20dmb.
