DRA**8M is a type of compact wireless voice transceiver
module. It integrates high speed microcontroller, high performance
wireless transceiver IC, high power PA, audio process and
squelching circuits. It provides standard UART interface which
users can easily configure appropriate parameters for different
applications. The module can work in low power and high power modes
by controlling related pin. Users can easily construct a
walkie-talkie system by connecting microphone, audio PA and
speaker.
