MICA
The MICA Mote is a second
generation mote module used for
research and development of low
power, wireless, sensor networks.
The MICA mote was developed
by UC Berkeley’s research group
on wireless sensors. It consists of:
sensor boards
· Plug-in
TinyOS
Distributed
· Software(TOS)
Operating System.
Atmega
128L
processor
· 916MHz or 433MHz
transceiver
· Attached AA(2) battery
pack

TinyOS is a small, open-source,
energy efficient, software
operating system developed by
UC Berkeley which supports large
scale, self-configuring sensor
networks. The source code and
software development tools are
publicly available at:
http://webs.cs.berkeley.edu/tos
TOS includes:
messaging
· Radio
hopping from
· Message

power modes
· Low

measurements and
· signal processing
Processor and Radio Platform
(MPR300CB):
The MPR300CB is based on the
Atmel ATmega 128L. The
ATmega 128L is a low power
microcontroller which runs TOS
from its internal flash memory.
The 128L has been selected for
its low power and other features.
The MPR300 (MICA) uses an ISM
band radio transceiver module for
wireless communication.
Sensor Boards:
Various sensor boards are
available from Crossbow and
other sources. These boards
connect onto the MICA through
a surface mount 51-pin connector.
The 51-pin connector supports
Analog Inputs, I2C, SPI, UART,
and a multiplexed Address/Data
bus. These interfaces make it
easy to connect to a wide variety
of external peripherals. Crossbow
supplies the following sensor
boards:
Photo diode/
· MTS101CA
Thermistor/Proto and

Notes: 433 MHz ISM band radio alternate is available - MPR310CA
Radio range dependent on antennae configuration. External antennae improves
range.
Base Station/ Interface Board:
The base station allows the aggregation
of sensor network data onto a PC or
other computer platform. The MICA
architecture is unique in that any sensor
node (MPR300CB) module can function
as a basestation by plugging the
MPR300CB processor/radio board into a
basic interface board, known as the
Mote interface board.
