1000m-1500m Micro Power RS-232/RS-485/TTL to RF Wireless Module

  • Specification & Feature

    HXJZ-881, the Micro-power wireless transceiver data module is used as the wireless data transceiver in short distance, with the small size, weight and power consumption and good stability and reliability.

    • uses GFSK modulation mode, reliable line of sight transmission distance up to 1000m;
    • Carrier frequency 490 MHz, measurement frequency band;
    • provides 8 channels;
    • interface / channel rate: 1200/2400/4800/9600bps;
    • Interface: TTL, RS-232, RS-485 selected by the user;
    • transceiver, half duplex, sending and receiving data conversionautomatically, as long as the interface to send / receive data to the conversion time is short;
    • transparent data transmission, can transmit long data frames;
    • can be used for point to point, multipoint, multi-pointcommunication and other combinations;
    • automatically filter out false data generated in the air, long-term reliability is good, very low failure rate;
    • Low power consumption and sleep function: power 50mw,receiving current <25mA, transmitting current <80mA, Sleep(custom) current <10uA;
    • Power Supply: TTL: DC +2.8 V ~ +3.3 V or +3.6 V ~ +5.5 V, RS232/RS485: DC +4.5 V ~ +5.5 V;
    • Temperature: -25 ℃ ~ +85 ℃;
    • size: 40mm * 24mm * 8mm (without antenna); Weight: 10 grams;
    • exchange model: HXJZ-88 series;
    • Standard antenna: a small rod antenna


    Using ADF7020 chip, small size, RF shielding means.
    Narrowband interference is strong, high receiver sensitivity, transmission is stable and reliable.
