Brief introduction
    HM-TRP series is a low cost, high performance transparent FSK wireless data transceiver module. It can work in 433/470/868/915MHz ISM band. Small size, high power, high sensitivity, transmission distance, high number of communications, internal auto-complete communication protocol conversion and data transceiver control features. UART serial data interface module, just to provide a serial data can be easily achieved wireless data transmission capabilities. Users also have the flexibility to configure the serial rate touch blocks according to their needs, frequency, transmitting power, communications, data rate, frequency deviation, receiving bandwidth parameters. HM-TRP series modules can be widely applied to various types of wireless data transmission field, is the ideal choice for the design of wireless data transmission products
