Description
If you are looking for long distance and easy to use serial wireless module, you have got it. This wireless serial port communication module is a new-generation multichannel embedded wireless data transmission module. 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 module is encapsulated with stamp hole, can adopt patch welding. There is a PCB antenna pedestal ANT1 on the module, and user can use external antenna of 434M frequency band through coaxial cable; there is also an antenna solder eye ANT2 in the module, and it is convenient for user to weld spring antenna. User could select one of these antennas according to use requirements. It is compatible (Wireless communication) with RFBee 434MHz UART Wireless module.
 
There is MCU inside the module, and user don’t need to program the module separately, and all transparent transmission mode is only responsible for receiving and sending serial port data, so it is convenient to use. The module adopts multiple serial port transparent transmission modes, and user could select them by AT command according to user's requirements. The average working current of three modes FU1, FU2 and FU3 in idle state is 80µa, 3.5mA an 22mA respectively, and the maximum working current is 100mA (in transmitting state).

Note: This is a transceiver (Transmitter and Receiver) module, you need 1 pair of this module for wireless communication.
 
Note: This wireless module cannot intercommunicate with the 1KM meters version (RF-UART-433-1KM) or RFBee 433MHz UART Wireless module as the frequency is not the same, not to forget, it is not compatible with the low cost RF transmitter and receiver too.
 
Features:
  • 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
