2. ZigBit Module Overview

2.1 Overview

The ATZB-RF-212B-0-U ZigBit is a compact, low-power, high sensitivity IEEE 802.15.4/ZigBee OEM module. Based on

a solid combination of the latest Atmel MCU Wireless hardware platform, 900MHz ISM band transceiver and Atmel

Studio Wireless Composer - the ZigBit offers an unmatched combination of superior radio performance, ultra-low power

consumption and exceptional ease of integration.

Figure 2-1. ATZB-RF-212B-0-U user interface diagram

This ZigBit module contains Atmel’s AT86RF212B 900MHz ISM band Transceiver for ZigBee and IEEE 802.15.4 [1].

The compact all-in-one board design of Radio Transceiver with very minimal components on the RF path to Antenna

connector dramatically improves the ZigBit’s compact size, range performance on signal transmission and increases its

sensitivity. This ensures stable connectivity within a larger coverage area, and helps develop appl ications on smaller

footprint.

ZigBit Module contains a complete RF design with all the necessary passive components included. The module can be

easily mounted on a simple 2-layer PCB with a minimum of required external connection. The ZigBit Module Evaluation

kit containing the ZigBit Extension board for the Atmel Xplained PRO HW Evaluation platform can be used to develop

FW using the Atmel Studio and evaluate using the Wireless Composer. Compared to a custom RF/MCU solution, a

module-based solution offers considerable savings in development time and NRE cost per unit during the HW/FW

design, prototyping, and mass production phases of product development.

ATZB-RF-212B-0-U [ZigBit 900MHz Wireless Modules]

42270B−WIRELESS−08/2014

Depending on end-user design requirements, the ZigBit can operate as a sensor node, where it can be paired with a

host processor driving the module over a serial interface.

The MAC stack running on the host processor can then control data transmission. Thus very minimal firmware

customization is required for successful module design-in. Third-party sensors can then be connected directly to the

host MCU.

Every ZigBit Module come pre loaded with Atmel assigned 64-bit MAC address stored in the EEPROM built-in the

module. This unique IEEE MAC address can be used as the MAC address of the end product, so there is no need to

buy a MAC address separately for the product using the ZigBit.

3.4 Mounting information

The Figure below shows the PCB pinout of a ZigBit module. Neither via-holes nor 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 via-

holes to be located right next to the pins thus minimizing inductance and preventing both mismatch and losses.

42270B−WIRELESS−08/2014

4.1 Handling Instructions

The ZigBit Modules are fixed with an EMI Shield to ensure compliance to Emission and Immunity rules. This shield is

galvanic and NOT air tight. So cleaning of the module with IPA / other similar agents is not advised. Humidity protection

coating (conformal) will cause deviated RF behavior and coating material being trapped inside EMI Shield. So this

should be avoided. For products requiring conformal coating, it is advised to suitably mask the ZigBit before applying

the coating to rest of the ZigBit carrier board. To protect ZigBit from humidity, the housing of the product should ensure

suitable Ingress Protection standards are complied with.

The UFL RF connector should never be exposed to Varnish / similar conformal coating material which will affect

electrical connection on the surfaces of connector.

The in-built chip antenna has been tuned for the particular design

4.2 General recommendations

• Metal enclosure should not be used. Using low profile enclosure might also affect antenna tuning

• Placing high profile components next to antenna should be avoided

• Having holes/vias punched around the periphery of the board eliminates parasitic radiation from the board edges

also distorting antenna pattern

• ZigBit module should not be placed next to consumer electronics which might interfere with ZigBit's RF frequency

band
