Overview
Ra-02 can be used for ultra-long distance spread spectrum communication, and compatible FSK remote modulation and demodulation quickly, to solve the traditional wireless design can not take into account the distance, anti-interference and power consumption.
Ra-02 can be widely used in a variety of networking occasions, for automatic meter reading, home building automation, security systems, remote irrigation systems, is the ideal solution for things networking applications.
Ra-02 is available in SMD package can be used for rapid production by standard SMT equipment.
It provides customers with high reliability connection mode.
