    433Mhz RF link kit

    The kit is consisted of transmitter and receiver, popular used for remote control.

    Basic Specification: 

    Frequency: 433Mhz.Modulation: ASK
    Receiver data output: High - 1/2 Vcc, Low - 0.7v
    Transmitor input voltage: 3-12V (high voltage = more transmitting power)
    Transmitting range (work at 5V): 40m indoor, and 100m in open air

    The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU, 
    PT2272(Encoder) and PT2262(Decoder) are optional, their existence is to 
    1) Avoid confusion when multiple RF links are in range 
    2) Isolate disturbance. 

    You can integrate the encoding and decoding work to the MCUs on both side. Whenever there is no 433Mhz devices around, you may use it as direct cable connection.
