433MHz RF Bus Transceiver Module, RS485 Serial Port, UART, DTU for PTZ Camera

Features: 1. Wireless transmission: This transceiver module can transmit wirelessly over long distances, up to 500 meters in open areas, with a baud rate of 10 kbps in air.2. One-to-one and one-to-many: This module can support transparent one-to-one and one-to-many communication via identification parameters3. Synchronous Change: Changing the baud rate of different serial ports will synchronously change the rate at which data is sent over the air4. Maximum transmission power: The maximum transmission power of this serial port is 100mW/20dBm, the power can be adjusted in 10 levels, the port has a built-in MCU, can use this serial port to communicate with external devices.5.
