The eRIC Development Kit provides a platform for the test and evaluation of eRIC radio transceivers and allows demonstration of
the transfer of serial data over the RF link and simple manual/auto transmit/receive modes.
The kit comprises:
Two eRIC400 (400MHz) or eRIC900 (900MHz) RF Transceiver modules
Two eRIC Development boards
Two matching antenna (400/900MHz) with SMA (Male) connectors
Two 9V Alkaline PP3 Batteries
Two USB Type A to Micro-B USB connector jump leads for connection to PC
One ‘Wireless Mike’ 4GB USB memory stick containing data sheets and software
Using this kit together with the supplied ‘easyRadio Companion’ software, connection can be made to the
eRIC modules allowing the default operating frequency (channels), RF power output, ‘Over Air’ and Host
serial communication rates to be configured and changed.
