Handling Instructions

4.1
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 MS-147 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

General Recommendations

4.2

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 RF frequency
band

Persistence Memory

5.
A dedicated memory space is allocated to store product specific information and called the Persistence Memory. The
organization of the persistence memory is as follows:

1. The MAC address stored inside the MCU is a uniquely assigned ID for each ZigBit and owned by Atmel.
Note:
User of the ZigBit application can use this unique MAC ID to address the ZigBit in end-applications. The
MAC ID can be read from the ZigBit using the Performance Analyzer Application that is supplied through
Atmel Studio Gallery Extension.
