DRA818V VHF Band Wireless Voice Transceiver Module -Blue+Silver+Yellow
DRA818V is a type of compact wireless voice transceiver module based on RFIC RDA1846 and works in VHF band (134MHz~174MHz). It integrates high speed microcontroller£¬ high performance wireless transceiver IC£¬ high power PA£¬ audio process and squelching circuits. The DRA818V module provides two power levels (0.5W and 1W) for selection. It has standard UART interface with which users can easily configure appropriate parameters for different applications. Users can easily construct a walkie-talkie system by connecting external microphone£¬ audio PA and speaker.
