Note:

1 . The supply voltage of the module affects the transmit power. Within the operating voltage, the lower the voltage, the smaller the transmit power. Remarks:

2 . When the operating temperature of the module changes, the center frequency will change, as long as it does not exceed the operating temperature, it will not affect the application.

3 . The antenna has a great influence on the communication distance. Please install the module correctly.

4 . How the module is installed affects the communication distance.
