EGS: A Cortex M3-Based Mote Platform

Free registration required

Executive Summary

The authors introduce the Egs mote platform based on the Cortex M3 microcontroller that focuses on medical sensing applications. Egs uses an Atmel SAM3U microcontroller that runs up to 96 MHz and has up to 52 KB of RAM and 256 KB of Flash. Egs combines this microcontroller with two radios (802.15.4 and Bluetooth), external flash, on board sensors, and a LCD touchscreen to enable a rich set of wireless sensing applications. Wireless Sensor Networks (WSNs) consist of low-power, embedded computing devices, known as motes, that use sensors to collect measurements from the physical world and its inhabitants.
