Evaluation Board 

The Evaluation Board (EVB) is the 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 including 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.
