BSN node
BSN node is a hardware platform designed for the ease of the development of pervasive health care system.  With a 8MIPS processor, a Zigbee ready RF link, a 512K EEPRM and a stackable design, the BSN node provides a low-powered, miniaturised, and intelligent platform for the development of pervasive physiological and context aware sensors.   Details can be found here.
