This module is based on SX1280,same drive way as SX1280,user can refer to SX1280 datasheet.



DIO is general I/O port，see more in SX1280 datasheet.



GDO 2 is generally configurated as IRQ function, IRQ pin can also be disconnected. The SPI query mode can be



used to obtain the interrupt status. However, it is recommended to use the external interrupt of the MCU.

After SX1280 restores IDLE mode or configures sleep mode, it is recommended that the power configuration table



be reinitialized.

It is recommended that the power output parameter of SX1280 set to - 2dBm. At this time, the output power of the



module can be 20dBm. When the output power of SX1280 is increased, the current will increase and the power will

not increase significantly.
