2. ZigBit Module Overview 2.1 Overview The ATZB-X0-256-4-0-CN 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, 900 MHz 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-X0-256-4-0-CN user interface diagram .
PAGE 7
Depending on end-user design requirements, the ZigBit can operate as a self-contained sensor node, where it would function as a single MCU, or 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 and manages module peripherals. Thus very minimal firmware customization is required for successful module design-in.

3.7 Antenna reference designs Multiple factors affect proper antenna match, hence, affecting the antenna pattern. The particular factors are the board material and thickness, shields, the material used for enclosure, the board neighborhood, and other components adjacent to antenna. Following guidelines need to be followed when designing the base board for the ZigBit. General Recommendations:  Metal enclosure should not be used. Using low profile enclosure might also affect antenna tuning.
