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. Its wireless working frequency band is 433.4-473.0MHz, multiple channels can be set, with the channel stepping of 400 KHz, and there are 100 channels in total. The maximum transmitting power of module is 100mW (20dBm), the receiving sensitivity is -117dBm at baud rate of 5,000bps in the air, and the communication distance is 1,000m (1KM) in open space. It is compatible (wireless communication) with RFBee 433MHz UART Wireless module.
 
The module is encapsulated with stamp hole, can adopt patch welding, and its dimension is 27.8mm×14.4mm×4mm (including antenna cap, excluding spring antenna), so it is very convenient for customers to go into application system. There is a PCB antenna pedestal ANT1 on the module, and user can use external antenna of 433M 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.
 
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, 3.6mA an 16mA 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 100 meters version(RF-UART-434-100M) or RFBee 434MHz UART module as both is operating at different frequency, not to forget, it is not compatible with the low cost RF transmitter and receiver too.
 
Features:
  • Long-distance wireless transmission (1,000m in open space/baud rate 5,000bps in the air)
  • Working frequency range (433.4-473.0MHz, up to 100 communication channels)
  • Maximum 100mW (20dBm) transmitting power (8 gears of power can be set)
  • Three working modes, adapting to different application situations
  • Built-in MCU, performing communication with external device through serial port
  • The number of bytes transmitted unlimited to one time
 
Specification:
  • Working frequency: 433.4MHz to 473.0MHz
  • Supply voltage: 3.2V to 5.5VDC
  • Communication distance: 1,000m in the open space
  • Serial baud rate: 1.2Kbps to 115.2Kbps (default 9.6Kbps)
  • Receiving sensitivity: -117dBm to -100dBm
  • Transmit power: -1dBm to 20dBm
  • Interface protocol: UART/TTL, Half Duplex
  • Operating temperature: -40℃ to +85℃
  • Dimensions: 27.8 x 14.4 x 4 mm

Can you provide the datasheet for all the chips?If possible the the circuiit diagram too... ( Wireless, 22/10/2019 )
Hi, we're sorry as we do not have the data for the time being. Sorry for the inconvenience caused. Thanks :)
it is imposible to this device give signal to the speaker? ( Muqri, 24/02/2019 )
Hi, this device will only give high and low output. So it is impossible to give a signal to a speaker. 
Hi

according to datasheet, it has operating range of "433.4-473.0 MHz",
what the different with "434MHz RF Transceiver Module (UART)-100m"?

I want to communicate with 433.92 MHz transceiver, which one is more suitable to use?
( chin yew, 15/01/2019 )

Hi, both of it is not suitable for 433MHz RF (UART) Transceiver Module-1km. You need the same model to communicate.

MY 433 MHz transceivers not pulling any current. When I transmit square wave, the receiver doesn't receive it. I feel like it is not transmitting. Why isn't module pulling any current ( gibay, 23/01/2018 )
Hi, can you email us your clear picture of setup to support@cytron.io. We will try to help you more as here is for short inquires only. Thanks.
I can communicate using serial port between two micro controllers when connecting them with wire, but it does not work when RF transceiver are connected. Baud rate in Micro-controller code is set to 9600. Why they aren't working. They are around 1 m apart. The receiving module does not receive any signal. I connected square wave from function generator to TX pin of module to see if receiver receives that signal. I am using the default settings of module. I didn't change frequency of TX and RX. They should be able to communicate.

I connected RF modules to 2 microcontrollers, but they are not communicating with each other. Can somebody tell why it doesn't work. ( Navi, 10/01/2018 )

hi sir, is this ASK or FSK? ( sriram, 30/11/2017 )
Hi, it should be FSK. For further questions, please visit to our technical forum for similar question or post your question there, as this session is only for short inquiry. Thanks.
Hi, when is this module will be restock? i need this asap. thank you ( ATIQAH HASSAN, 24/10/2017 )
Hi, it will be restocked in 2 weeks. Thanks.
I can buy a PSK or QPSK rf module. How can I find it? ( Nihat DALDAL (nihatdaldal@yandex.com), 14/06/2017 )
Hi, sorry we don't have that kind of RF module. Thanks.
