1.0 Overview

The LRNHEL Long Range Transceiver module is based on the Microchip RN2903 module and establishes              

an encrypted long range communication link between a base station and the processor this module is               

connected to. It is electrically identical to the Microchip RN2903 module and the same UART commands               

can be used to interact with it.
