The VW320A series wireless module provides the capability of a short range,reliable wireless point-to-point,point-to-multipoint and mesh network RF data communications link.  They can  be  used  in  a  variety  of  data  communications applications that require a simple to use invisible data link.

The wireless modules are designed to operate in the unlicensed ISM frequency band (315MHz/433MHz/868MHz/915MHz ISM band) and are therefore acceptable for use in many countries. 
● 4 Operation modes: Transparent mode,Transparent secured mode,Addressed mode and Addressed secured mode.
● Repeater supported 
● Integrated wireless link protocols 
● Deep sleep mode (Power down mode) /Wakeup Control 
● Server-Client mode
● Broadcast Multi-drop mode
● Easy configuration by AT commands.
● Easy configuration with a user friendly control panel on PC.
