ZigBit is a low-power, high-sensitivity IEEE802.15.4/
ZigBee-compliant OEM module. This multi-functional
device occupies less than a square inch of space, which
is comparable to a typical size of a single chip. Based on
a solid combination of Atmel’s latest AVR Z-Link
hardware platform [1], the ZigBit offers superior radio
performance with exceptional ease of integration.
ZigBit modules comply with the FCC (Part 15), IC and
ETSI (CE) rules applicable to the devices radiating in
uncontrolled environment. For details, see section
Agency Certifications
ZigBit fully satisfies the requirements of the “Directive
2002/95/EC of the European Parliament and the Council
of 27January 2003 on the restriction of the use of certain
hazardous substances in electrical and electronic
equipment” (RoHS). MeshNetics provides fully compliant
product in all regions where the directive is enforced July
1, 2006.
The
Microcontroller [1] and AT86RF230 RF Transceiver [2].
The module features 128kb flash memory and 8 kb RAM.
The ZigBit already contains a complete RF/MCU-related
design with all the necessary passive components
included. The module can be easily mounted on a simple
2-layer PCB. Compared to a single-chip, a module-based
solution offers considerable savings in development time
& NRE cost per unit during the design & prototyping
phase.
Innovative (patent-pending) dual chip antenna design in
ZDM-A1281-A2 module eliminates the balun and
achieves good performance over ZigBee frequency
band.
MeshNetics provides tools for building ready-to-use
applications around the ZigBit module. The Development
Kit helps prototyping and testing an 802.15.4 or ZigBee
networking solution. It includes the sensor boards with
multiple interfaces, an out-of-the-box data acquisition
software
documentation. The sample data-acquisition application
allows network monitoring and sensor data collection, all
visualized via graphic interface.
The ZigBit modules come bundled with the eZeeNet
networking firmware. The eZeeNet enables the module-
based OEM products to form self-healing, self-organizing
mesh networks. The eZeeNet stack conforms to
IEEE802.15.4/ ZigBee specifications [3], [4], [5].
Depending on your design requirements, you can use
the ZigBit to operate a sensor node, where it would
function as a single MCU. Or you can pair it to a host
processor, where the module would serve essentially as
a modem.
In the former case, a user application should be bundled
with the eZeeNet Software. The eZeeNet’s programming
interface gives users flexibility to manage network and
minimize power consumption.
