Serial RF Module 433Mhz

 Serial transceiver module is a low cost, high performance transparent FSK transceiver with operating at 434 MHz. It features small size, high output power, high sensitivity, long transmission distance and high communication data rate with auto set up for communication change and data receiving and transmission control. There is UART interface, it is easy to realize the wireless data transmission with only providing the UART data. It is flexible for the users to set the UART baud rate, frequency, output power, data rate, frequency deviation, receiving bandwidth etc parameters. It is your ideal choice for designing wireless data transmission products which can be widely used on wireless data transmission field.
 
The single module can not work, please get two or more of these modules.

    Wireless communication frequency band is 434M
    Multiple types of serial port transparent transmission modes have respective features, and the mode is changed by command
    User needn't program the modules, and four modes are only responsible for receiving and sending serial port data, and are convenient to use
    Low current consumption; the idle current is 80μA, 3.5mA or 22mA, depending on the selected mode
    The number of bytes sent to serial port of module unlimited to one time
    All functions and parameters are changed by command, and can be saved in case of power failure
