Feature:
1. : This transceiver module can transmit wirelessly over long distances, up to 500 meters in open areas, with baud rate of 10kbps in the air
2. One to One and One to Many: This module can support one to one and one to many transparent communication through ID settings
3. Synchronous Change: Changing the baud rate of different serial ports will synchronously change the rate at which data is sent over the air
4. Maximum Transmit Power: The maximum transmit power of this serial port is 100mW/20dBm, the power can be set to 10 levels, the port has built in MCU, can use this serial port to communicate with external devices
5. Application: This module can be used for IP PTZ camera, LED controller, instrument, identification system and etc.
