      ● frequency: 433mhz.also can customiz other frequency bands. such as 300-350 mhz, 390-460 mhz and 780-925        mhz

    ● interfaces: rs-232, ttl or rs-485.

    ● data format：8n1/8e1/8o1(other formats can also be provided, such as 9-bit data bits to meet the                requirements of multi-machine communication)

    ● baud rate: 1200, 2400, 4800, 9600, 19200, 38400, 100kbps, 250kbps;

    ● 16 channels, if needed, 32/64 channels are available to satisfy various configuration of communication          at the same time；

    ● transparent data transmission,transparent data interface used in transceivers is for meeting many              standard or nonstandard user protocols. any false data generated in air can be filtrated automatically          (what has been received is exactly what has been transmitted)；

    ● transceiver integration, half-duplex operation mode.

    ● single-chip radio frequency integrated circuit and single-chip mcu have few peripheral circuits, low            power consumption and high reliability.

    ● low cost, low power consumption

    ● operating temperature: -35°c to 75°c (industrial grade)

    ● antenna impedance: 50ω (standard sma, customizable)

1、the led indicator light will glitter green continually while receiving data from air.

2、 the led indicator light will glitter red continuously when transmitting data into air after receiving from com.

power supply：
        3.1~5.5v dc,please note that module transmiting may affect switching power supply stability. therefore, try to avoid using the switching power supply, or try to assure the distance between the module antenna and the power supply. for the best communication effect, please use a power supply with a smaller ripple factor. the maximum output current of the power supply should be more than 1.5 times the maximum operating current of the module.
