Abstract--We introduce the Egs mote platform based on the
Cortex M3 microcontroller that focuses on medical sensing appli-
cations. 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.
I. INTRODUCTION
Wireless sensor networks (WSNs) consist of low-power,
embedded computing devices, known as motes, that use sen-
