12.PCB Layout Recommendations

Please reference Mechanical Dimensions shown in next section for PCB layout.

The area underneath the module should be covered with solder mask in order to prevent short

circuit on the test pads on the back side of the module. A solid ground plane under the module is

preferred.

As the module integrated with onboard PCB trace antenna, the mounting position of the module will

have great impact on the RF performance. There should not be any trace, ground plane or metal

part underneath or nearby the area of the onboard PCB trace antenna. The figure below shows an

example how the module positioned on the mother PCB.
