Recommended PCB Layout
The hole pattern and mounting dimensions for the XPort AR are shown in the following
illustration. For proper heat dissipation, it is recommended that the PCB have approximately
1 square inch of copper attached to the shield tabs. The shield tabs are an important source
of heat sinking for the device.

XPort Compatibility
The XPort AR is designed for the PCB layout to accommodate either an XPort AR or the
original Lantronix XPort. To accomplish this, a few extra holes are required. The hole
pattern and mounting dimensions for this combination XPort/XPort AR footprint are shown in
the following drawing:
