The new EZLink modules are 37 mm x 22 mm and based around pre-certified IEEE 802.15.4 radios operating in the 2.4 GHz band. The module is supplied in two different versions including a full-function embedded ZigBee module, and a serially interfaced AT command set embedded ZigBee module. All modules hold the official ZigBee certification.

The full-function embedded ZigBee module, IA OEM-DAMD1 2400, provides a pre-certified 'ZigBee-compliant platform' with the home controls stack profile, and can be configured as a coordinator, a router or an end device. The module supports multiple sleep modes and full 128-bit authentication. A full ZigBee API is available through an RS-232 bisync serial interface.

For existing equipment, a wireless ZigBee connection can be added through a serial interface version of the module, the IA OEM-DAMD2 2400. This adds a private serial port profile on top of the 'ZigBee-compliant platform' thus allowing RS-232 links to be run transparently across a ZigBee network. The device is controlled by way of simple 'AT' commands.
