Mosaic Industries' compact (2 by 2.5 in.) Ethersmart Wildcard module links a Lantronix 10/100-MHz Ethernet-based XPort (see "Ultra-Small Server Web-Enables Any System") with other Wildcard modules like the 16-MHz Freescale 68HC11F1-based QCard Controller. The host can power down the XPort to conserve power. The Ethersmart Wildcard costs $140.
