The VW321A 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.
