PCB Footprint & Dimensions¶

Recommended PC Board Layout¶

The hole pattern and mounting dimensions for the XPort EDGE unit are shown in the following drawing:

For proper heat dissipation, the PCB should 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.
