DRMA-81: 802.11 b/g 54Mbps wifi mini-PCI module, half-size, MB55/AR2417

DRMA-81 is an IEEE802.11 b/g 54Mbps wifi mini-PCI module in half-size type IIIA form factor with two U.FL connectors designed specifically for integration in performance-critical applications with space limitation. Supporting 108Mbps Super G 802.11g 54Mbps, DRMA-81 has the capability of full size mini-PCI in half-size IIIA form factor at competitive price. It is ideal for embedding into new or existing ergonomic devices such as gateway/routers, notebooks, and application-specific devices (ASDs) used in vertical market.
Linux 2.6 AP/Router driver reference code support enables gateway/router manufacturers to provide products that enjoy improved wifi performance and time to market through trouble-free WiFi integration.
