️Warm Reminder

It is recommended to control the output power of the SX1280 chip between 2-5 dBm when using the SX1280 PA module, to ensure that the entire module outputs a power of 20 dBm.

If the output power of the SX1280 chip is higher than 5 dBm, it will exceed the maximum allowable input for the FEM chip and cause damage.

However, if the output power is lower than 2 dBm, the module's output power will still be within 20 dBm.

Therefore, the output power setting of the SX1280 chip must be carefully controlled and not exceed 2-5 dBm to avoid damaging the FEM chip.

Setting the output power to 3 dBm will ensure an output power of 20 dBm.
