Note: The lower the transmit power, the closer the transmission distance, but the working current will not decrease proportionally.
It is recommended to use the maximum transmit power.

Note: The higher the air rate, the faster the transmission rate, but the shorter the transmission distance; therefore, if the rate meets
the requirements for use, it is recommended that the lower the airspeed, the better.

★ Note: It is recommended to reserve more than 50% of the current margin when selecting the power supply, which is conducive to
the long-term stable operation of the radio.

512 bytes
Automatically send 58 bytes per package
Note: 1. When the receiving data is more than a single packet capacity (100 bytes), the beyond part will be
automatically assigned to the second transmission until it is completed;
2. The data transceiver can not receive data which is more than the buffer capacity;
