 EVK1100
 Evaluation kit and development system for
the AVR32UC3A family
 EVK1100 is a fully functional embedded
computer system.
 Circuit board has a flexible power system
that accepts 8-20V DC input and can be
operable via USB port.
 The EVK1100 embeds an Atmel Data
flash
(8MBytes)
and
a
SDRAM
(32MBytes).
 Several communication interfaces are
available on the EVK1100: RS232, USB
and ETHERNET.

 Our WSN Platform (Sentio)
o Number of different platforms targeting different application areas
 SENTIO
SENTIO32:
a stackable platform developed in 2004 (IEEE802.15.4
compatible(Zigbee), having three layers i.e communication layer, processing
layer (Atmel Mega 128L 8-bit uC), and analog/digital interfaces to sensor layer.
Sufficient
for short
communication.
A latest
platform
thatrange
is very
compact
SENTIO-HP high-precision
instrument that can be used for
with 
(IEEE802.15.4
compatiblewireless
(Zigbee))
characterizing processes
and processor
(AVR32) on the same
board. SENTIO-BT for urban sensing applications.
 SENTIO-e2 for environmental monitoring, communicating at 433MHz at
ranges up to 1 km. Global communication via GSM/GPRS or to a PC via USB
It is a Development Board, can be used
for variety of wireless sensor applications
