En dit zit er allemaal in
DRA818V is a type of compact wireless voice transceiver module based on RFIC RDA1846 and works in VHF band. 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. Users can easily construct a walkie-talkie system by connecting microphone, audio PA and speaker.
Ik kan helaas op het ogenblik geen foto uploaden maar het meet slechts 36 x 18 mm en is 3 mm dik.
