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. ZDM-A1281-B0 Block Diagram ZDM-A1281-A2 Block Diagram eZeeNet™ Block Diagram
ZigBit™ OEM Modules Product Datasheet © 2007 MeshNetics Page 5 of 22 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.

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 © 2007 MeshNetics Page 11 of 22 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. D_VCCDGND1,8...3,6 V 9.

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 © 2007 MeshNetics Page 13 of 22 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 © 2007 MeshNetics Page 16 of 22 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.
