NOTE: TXD, RXD of UART are crossed inside ZigBit Module. External UART devices connecting to ZigBit Module
should follow straight connection for UART.

The Figures 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. 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.
