3.1 ATZB-EVB (MeshBean) Featured Components
ZigBit Module
ZigBit module is an ultra-compact, low-power, high sensitivity 2.4GHz
802.15.4/ZigBee OEM module from Atmel. ZigBit module is based on Atmel’s Z-Link
2.4GHz platform. It includes ATmega1281V Microcontroller and AT86RF230 RF
Transceiver.
In ZDK, every ZigBit module is delivered installed on a ATZB-EVB (MeshBean)
board. Two different versions of ZigBit modules are available [1]: a version with
balanced RF port for applications where the benefits of PCB or external antenna can
be utilized, and a version with dual chip antenna satisfying the needs of size-sensitive
applications.
Detailed specifications of the ZigBit module, including the module interfaces, voltage
levels, power consumption, are available in the ZigBit datasheet [1].
Sensors
The board incorporates light sensor TSL2550T from TAOS and temperature sensor
LM73CIMK from National Semiconductors. Both sensors are connected in parallel to
the I
2
C bus. For more information on the sensors see their datasheets [13], [14]
available from the corresponding manufacturers’ websites.
NOTE:
In addition to the built-in, onboard sensors, external sensors selected
by developer can be used. An external sensor can be connected to
the terminals of External interface cable leading to the onboard
Expansion slot. See the corresponding pinout in Table 2. As an
example, connection of an external sensor is illustrated in Application
Note [7].
USB to UART Bridge
CP2102, the USB to UART Bridge controller from Silicon Labs [15], is installed on the
board. It provides seamless USB interface to any RS-232 legacy device. If the
controller’s driver has been installed on PC during the deployment of the whole
Development Kit (see Section 4.3) the onboard USB port is visible on the PC as
generic COM port with a particular number.
