⚫ With SX1280+PA+LNA，its driving method is similar to SX1280, please refer to SX1280 datasheet for operation guidance;
⚫ GDO0 is GPIO，refer to SX1280 datasheet for details;
⚫ GDO2 is generally configured as an IRQ-like function, or it can be disconnected. The SPI query mode can be used to obtain the
interrupt status, but it is recommended to use the external interrupt via connecting MCU;
⚫ After the SX1280 restores the IDLE mode or configured in sleep mode, it is recommended to reinitialize the power configuration
table;
⚫
It is recommended that the power output parameter of the SX1280 be set to 0dBm. At this time, the module outputs 27dBm. When
the output power of the SX1280 is increased, the current will become larger and the power will not increase significantly.
