Chapter 1:About the Module

The Digi Connect Wi-Wave module is an 802.11b/g WLAN communications module for use in embedded applications. The module is a single circuit card packaged in a PCI Express Mini Card form factor, and supports all the RF, analog, and digital circuitry necessary to implement WLAN functionality. Using Digi’s baseband processor technology, this module is the ideal choice for embedded applications requiring long-term product availability in conjunction with reliability and easy design integration.

The primary interface to the module is through a standards-compliant PCI Express Mini Card edge connector, using a USB 2.0 full speed/high speed link for communication with the host system.

Note: The Digi Connect Wi-Wave edge connector pinout is compliant with the PCI Express Mini Card Electromechanical Specification, Revision 1.1 (March 28, 2005) with this exception: the Digi Connect Wi-Wave has a 4-wire JTAG programming interface mapped to pins 45, 47, 49, and 51.

The Digi Connect Wi-Wave module also provides a dual diversity antenna option through two on-board U.FL connectors, which allow for cabling to remote 2.4 GHz antennas.
