ZigBit™ Module Overview

ZigBit is a low-power, high-sensitivity IEEE802.15.4/

ZigBee-2006 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 below.

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 ZigBit contains Atmel’s ATmega1281V

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) 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 Evaluation

Kit and the Development Kit help 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 suite, as well as

accessories and documentation. The sample sensor data

acquisition application allows network monitoring and

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.

ZigBit™ OEM Modules Product Datasheet

In the latter case, the host processor can control data transmission and manage module peripherals via powerful set

of AT commands. This way, a minimum engineering effort for development of customer’s devices is required.

Additionally, the sensors can be connected directly to the module, thus expanding the existing set of sensor

interfaces. The over-the-air control via AT-commands makes debugging and network testing easier. It also enables

wireless module configuration during OEM mass-production process and provides flexible commissioning protocol

for installation and maintenance of ZigBit-based devices.

The eZeeNet is compact private profile software from MeshNetics that is specifically tailored for data acquisition

applications. It allows optimizing the network traffic, reducing power consumption, scheduling, and smart power

management. The eZeeNet software comes with a set of drivers for standard peripherals (I2C, GPIO, ADC, etc.) that

ensure the ZigBit module easy integration.

Notes:

1. *Most of pins can be configured for general purpose I/O or for some alternative functions as described in

details in the ATmega1281V Datasheet [1].

2. GPIO pins can be programmed either for output, or input with/without pull-up resistors. Output pin drivers

are strong enough to drive LED displays directly (refer to figures on pages 387-388, [1]).

3. All digital pins are provided with protection diodes to D_VCC and DGND

4. It is strongly recommended to avoid assigning an alternative function for OSC32K_OUT pin because it is

used by eZeeNet Framework. However, this signal can be used if another peripheral or host processor

requires 32.768 kHz clock, otherwise this pin can be disconnected.

5. Normally, JTAG_TMS, JTAG_TDI, JTAG_TDO, JTAG_TCK pins are used for on-chip debugging and flash

burning. They can be used for A/D conversion if JTAGEN fuse is disabled.

6. eZeeNet software can configure as general-purpose I/O lines the following pins: GPIO0, GPIO1, GPIO2,

GPIO3, GPIO4, GPIO5, GPIO6, GPIO7, GPIO8, GPIO9, I2C_CLK, I2C_DATA, UART_TXD, UART_RXD,

UART_RTS, UART_CTS, ADC_INPUT_3, ADC_INPUT_2, ADC_INPUT_1, BAT, UART_DTR,

USART0_RXD, USART0_TXD, USART0_EXTCLK, IRQ_7, IRQ_6. Additionally, four JTAG lines could be

ZigBit™ OEM Modules Product Datasheet

programmed with software as GPIO as well, but this requires changing the fuse bits and will disable JTAG

debugging.

7. CTS pin can be configured by eZeeNet to indicate sleep/active condition of the module thus providing

mechanism for power management of host processor. If such functionality is needed, it is recommended to

connect external pull-down resistor to this pin to prevent undesirable transients during module reset

process.

8. It is recommended to use ferrite bead and 1 µF capacitor located closely to the power supply pin, as shown

below.

The above diagrams show the recommended PCB layout for ZigBit module. No via-holes and no wires are allowed

on the PCB upper layer in the area occupied by the module. As a critical requirement, RF_GND pins should be

grounded via several holes located very close to pins thus minimizing inductance and preventing mismatch and

losses.

ZigBit™ OEM Modules Product Datasheet

Sample Antenna Reference Designs

The following reference antenna design shows an example that can serve as a basis for further optimization.

The symmetric dipole antenna shown below has been tuned for a particular case, so the cut-and-paste approach

would not necessarily ensure an optimum performance because of multiple factors affecting the antenna matching

and pattern (for instance, the board material and thickness, shields, the material of enclosure, the board

neighborhood, other components located next to antenna and so on). As a general recommendation, metal

enclosures or setting high profile components closely to antenna should be avoided. Using low profile enclosures

can, furthermore, cause antenna tuning. The holes shown located around the board eliminate the undesirable

antenna pattern distortions which might be induced by radiation from the board edges. The ZigBit module should not

be placed next to components causing undesirable interference in its operating frequency band or adjacent bands,

such as GSM, CDMA, WiFi, and Bluetooth.

ZigBit™ OEM Modules Product Datasheet

Normally chip antennas are more tolerant of board and enclosure materials, and ZigBit module neighborhood;

however, general recommendations for board design for the PCB antenna version still apply.

The board should be designed such that it prevents propagation of microwave field inside the board material itself.

High frequency electromagnetic field may penetrate the board and radiate from the edges of the board causing

undesirable pattern distortions. To eliminate this effect, it is often enough to surround the board with metallized

holes connected to module ground.

Since the module with chip antenna is tuned for installation on FR-4 board with thickness 1.6 mm, the performance

is guaranteed only if the board is designed according to the diagram below. Deviations from this design may change

the performance.
