Evaluation
Board

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.
