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 a successful module design-in. Third-party sensors can then be connected directly to the module, thus expanding the existing set of peripheral interfaces. ATZB-S1-256-3-0-C ZigBit 2.

NOTE: TXD, RXD of UART are crossed inside ZigBit Module. External UART devices connecting to ZigBit Module should follow straight connection for UART: UART_TXD_external_device <-> UART_TXD UART_RXD_external_device <-> UART_RXD 3.4 Mounting Information The Figure below shows the PCB layout recommended for a ZigBit module. Neither via-holes nor wires are allowed on the PCB upper layer in the area occupied by the module.

Figure 3-4. ATZB-S1-256-3-0-C Mounting Information The ZigBit’s location and orientation on the carrier board is illustrated in the above PCB Land pattern and Mounting information drawing. The Recommended placement of ZigBit on Carrier Board needs to be accurately followed to ensure performance on the end application 3.5 Soldering Profile The J-STD-020C-compliant soldering profile is recommended according to Table 3-9. Table 3-9. (1) Soldering Profile .

3.6 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.
PAGE 17
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.
