1 Introduction
Intended Audience and Purpose
This document is intended for engineers and software developers working with the
ZigBit™ Development Kit (ZDK). The Kit is used to evaluate the performance and
features of ZigBit modules and the BitCloud software, and to implement custom
applications on top of BitCloud API.
Safety and Precautions
The product contains electronics, which are electrically sensitive. Please take
necessary precautions when using such devices. Atmel does its best to protect the
product components from electrostatic discharge phenomena, but we encourage our
users to follow common guidelines to avoid electrostatics by using proper grounding
etc.
The product complies with the FCC (Part 15), IC and ETSI (CE) rules applicable to
the devices radiating in the uncontrolled environment. Please find out if the product
complies with your local regulations.
Any modifications of the hardware, its components or improper use of the product can
cause an uncontrolled violation of the in-band or out-band radiation levels. It can
result in progressing violation of emission level limits, thus causing harmful
interference.
Precautions
The product radiates power in the microwave band. Although the levels are
considered to be low (less than 2 mW), it is reasonable to protect the operating
personnel from possible harmful impact of the electromagnetic field. When the parts
of the product are turned on, an operator should avoid touching the PCB antenna and
the board itself. The recommended distance between an operator and antenna
should be more than 20 centimeters.
AC/DC adapters which can be used with the product contain high voltage circuits.
General precautions should be taken against electric shock before the product
hardware is mains powered.
The ZigBit Development Kit contains fragile components. Please handle with care.

2 Development Kit Overview
ZigBit™ Development Kit (ZDK) is a simple, out-of-the-box solution designed for full
range of WSN prototyping and development. It comes complete with ATZB-EVB
(MeshBean) development boards containing ZigBit modules and a variety of tools to
test the wireless network features and performance and to develop customized
wireless solutions based on BitCloud Software.
ZigBit Development Kit includes:
1. Any one type of ATZB-EVB (MeshBean) board (1 item) –
ATZB-EVB-24-SMA/ ATZB-EVB-900-SMA/ ATZB-EVB-24-
A2/ ATZB-EVB-A24-SMA/ ATZB-EVB-24-PCB
2. USB 2.0 A/mini-B cable (3 items)
3. Swivel antenna (1/2 wave antenna)
4. Software & Documentation Distribution CD (1 item).
3 Hardware General Specifications
ATZB-EVB (MeshBean) board is intended to evaluate the performance of a ZigBit
module. In turn, a ZigBit module with the embedded BitCloud software provides
wireless connectivity for ATZB-EVB (MeshBean) board, enabling it as a node in a
ZigBee network. MeshBeans also serve as a reference hardware platform for the
customer’s target devices utilizing ZigBit modules for wireless communication.
The ATZB-EVB (MeshBean) board can be configured to operate as a network
coordinator, a router or an end device, by setting of DIP switches (see Section 0)
and/or sending AT-commands. The node’s role is defined by the embedded
application.
The boards are delivered with ZigBit preprogrammed with Serial Bootloader and
WSNDemo application firmware. For full list of demo applications see Section 3.2.
Gerber files are available with Complete Support Package only.The ATZB-EVB
(MeshBean) basic parameters are presented in Table 1.

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.
