PCB Footprint

mechanical drawing of the XEM7305 is available in PDF and image formats.  The PCB is 64mm x 42mm (2.52″ x 1.65″) with four mounting holes (M2 metric screws) spaced as shown in the figure.  These mounting holes are electrically isolated from all signals on the module.

The XEM7305 has a two 80-pin Samtec BSE connectors providing access to 108 I/O including 6 MRCC pins.

Mating Board Diagram

Use the mating diagram below to orient and design peripheral mating hardware. Note that this is a top-down view and mates to the top of the XEM7305. This design is realized in Altium CAD drawings in the corresponding breakout board which are available through Pins Downloads.
