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 I2C 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.
Silicon Serial for UID storage

9 ATZB-EVB-XXX-XXX User Manual AVR-09-2011
UID (Unique Identifier) is HEX value, 8 bytes long. UID is used for setting unique
MAC address of the node.
UID is hardware defined value. It is programmed into a chip (Silicon Serial Number
DS2411R+ by Maxim/Dallas) at the factory.
UID is unique, and cannot be overwritten. In order to ensure the presence of UID on
the board it is required to execute Hardware Test application (see Section 4.7 for
details).
ATZB-EVB (MeshBean) Board Design
The ATZB-EVB (MeshBean) board contains the ZigBit module, which operates as
ZigBee/802.15.4 transceiver. It also includes sensors, buttons, DIP switches, and a
set of interfaces.
The board provides the following interfaces:
USB 2.0 port
Light and temperature sensors
2 push buttons controlling the software
Reset button
3 DIP switches
3 software-controlled LEDs
Symmetrical dipole PCB antenna (only for ATZB-EVB
(MeshBean) with PCB antenna)
SMA connector (only for ATZB-EVB (MeshBean) with
external antenna)
JTAG connector for software upload and debugging
Power connector (3 V) to use an AC/DC adapter (not
supplied with ZDK)
20-pin Expansion slot containing external ZigBit’s interfaces
(see Table ), including:
Serial port interface (RS-232)
USART
Buffered I2C interface with ESD protection and voltage
level translation
ADC/GPIO
Battery compartment for AA-size batteries
3 configuration jumpers
3 clamps for power consumption measurements.
Also, the board contains an internal voltage regulator to supply most of the
components with 3.6 V. This is needed if ZigBit’s MCU is to be run at 8 MHz.1.
NOTE:
Normally ZigBit module is powered directly by the batteries, USB or
AC/DC adapter (via protection circuitry); however, Jumper J2 (see
Table ) can switch ZigBit to 3.6 V supply.
See Figure 1 for the layout of ATZB-EVB (MeshBean) version with integrated PCB
antenna and the board’s functional diagram.
18MHz requires changes in the BitCloud Software that normally runs at 4 MHz in
order to extend the voltage range and decrease power consumption.

pins directly. Thus this interface should be used with precautions at
the low supply voltages to avoid damaging the module.
Pins 7 and 8 are connected via voltage level translators with ESD
protection. Thus these pins can be used easily to connect extra I2C
sensors without extra logic.
Voltage on the V_XX pin does not depend on the state of jumper J1 or
ammeter connection between clamps CM+, CM-.

3.2 BitCloud Software
BitCloud is a full-featured, next generation embedded software stack from Atmel. The
stack provides a software development platform for reliable, scalable, and secure
wireless applications running on Atmel ZigBit modules. BitCloud is designed to
support a broad ecosystem of user-designed applications addressing diverse
requirements and enabling a full spectrum of software customization.

15 ATZB-EVB-XXX-XXX User Manual AVR-09-2011
BitCloud is fully compliant with ZigBee PRO and ZigBee standards for wireless
sensing and control. It provides an augmented set of APIs which, while maintaining
100% compliance with the standard, offer extended functionality designed with
developer's convenience and ease-of-use in mind.
The topmost of the core stack layers, APS, provides the highest level of networking-
related APIs visible to the application. ZDO provides a set of fully compliant ZigBee
Device Object APIs which enable main network management functionality (start,
reset, formation, join). ZDO also defines ZigBee Device Profile types, device and
service discovery commands implemented by the stack.
This ZDK provides everything a developer would need to develop custom applications
based on the BitCloud API [4]. The general guidelines to BitCloud programming are
given in [5]. API-based demos are provided in source code which can be modified
and extended, making it possible to develop WSN applications for a variety of
networking scenarios. For example, an end device can be configured to communicate
with a router between the periods of sleep thus saving power.
Another configuration of BitCloud Software, SerialNet, enables a user to implement
customized WSN scenarios without developing any WSN application code. In this
case WSN nodes are controlled via AT-commands (see Section 6).
The structure of BitCloud Software is presented in Figure 2. It is detailed in datasheet
[2].
Figure 2. BitCloud Block Diagram
The Development Kit includes two kinds of applications (see 10.7). Evaluation tools
are delivered in binary format. Sample applications are available in source code.

http://java.sun.com/javase/downloads/index.jsp.
There may be other Java instances already installed on your computer before the use
of ZDK. To avoid confusion, edit start.bat file in /Evaluation Tools/WSNDemo
(WSN Monitor) subdirectory containing the WSN Monitor. Make sure to provide
full path to the Java executable file, specify its file name extension (.exe) explicitly.

20 ATZB-EVB-XXX-XXX User Manual AVR-09-2011
Current version of the AVR Studio [16] with Service Pack can be freely downloaded
from the Atmel’s website (http://www.atmel.com). Simply launch the downloaded
installer programs and follow the setup instructions.
The WinAVR suite of development tools can be downloaded from
http://sourceforge.net/projects/winavr. To install WinAVR follow the setup instructions.
4.4 Connecting the Board to PC
The board can be connected to host PC via USB port, using USB 2.0 A/mini-B cable
supplied within the Kit. USB is typical connection. Furthermore, it provides the
convenient possibility to link multiple boards to a single PC. Besides, no battery is
required once a board is powered via USB.
Because wireless applications usually employ host connection through COM port,
linking the onboard USB to UART Bridge controller to PC requires installation of the
USB to UART Bridge VCP driver (see details in Section 4.3, Section 0). As a result,
generic COM port can be used to access a board via USB.
IMPORTANT NOTES:
When USB connection is used, the COM port number would be
changed by the Windows operating system if the board has been
reconnected. To avoid confusion use Windows Control Panel to check
on the actual port number.
Under some circumstances, the boards can conflict with other USB
devices recently installed. In such cases, the Windows Device
Manager would show a problem occurred during the plug-and-play
procedure or it would not detect the USB to UART Bridge controller at
all. Possible solution is to change the USB ID for the board, using
special utility available from the controller’s manufacturer. See Section
9 for details.
Alternatively, the board can be connected to host PC via serial port, using a serial
cable (not provided with ZDK). Serial port pinout is presented in Table .
IMPORTANT NOTE:
USB and serial port (RS-232) share the same physical port on the
board. They cannot be used at the same time.
Keep in mind that the connection mode is controlled by setting of jumper J3 (see
Table ).
