    2KM Long Range RF link kits w/ encoder and decoder This is a super long-range 433mhz RF link kit. It comes with VCO, PLL technology, steady frequency and super anti-jamming ability. You can directly use it with your projects, like wireless data transport, remote control, etc. Specifications Parameter  Value  Working voltage  Receiver(3‐5V), Transmitter(3‐9V)  Working current  ≤2.5mA(5.0VDC)  Principle of operation  Superhet（VCO, PLL）  Modulation  OOK/ASK  Parameter  Value  Working band  433.92MHz (customized service available)  Bandwidth  1.5MHz  Sensitivity  ‐105dBm (50Ω)  Rate  ＜5Kbps  Decoding form  PT2272  Antenna length  18cm  Transmission range  2 km  Application Ideas  Wireless switch  Remote transmission  Wireless control Hardware Overview Getting Started  Please follow the Instruction to hook up the communication system.  Connect battery, button and transmit boards. Note Please use 3-5V power source! 9V will damage the receiver board. Connect battery, LEDs and receiver boards. Note Do not put RX module and TX module too close: this would prevent them to work. Make sure that the RX module and TX module are at least 1 meter away from each other.  When we press the button on the Transmitter side, the related LED on receiver side will be turned on.
