The Evaluation Board (EVB) is most simple & efficient way to test and evaluate the Weightless

End Device Module.  The End Device Module is

a Low-Power Long Range module with a full Weightless protocol stack up to the AT command interface. The AT command interface offers

rapid time to market. With UART & GPIO interfaces, the EVB allows users to quickly program settings,

add sensors, and create prototypes.
