PCB Footprint

The XEM8310 PCB is 100mm x 70mm (3.94″ x 2.76″) with four mounting holes placed near the corners. These mounting holes are electrically isolated from all signals on the XEM8310. Power and USB Type C are located along one edge of the PCB. Three 80-pin expansion connectors are available on the bottom-side of the PCB.

Mechanical Drawing

The mechanical drawing below may be used for enclosure or mounting hardware design. 3D Models are also available in SolidWorks, STEP, and IGES formats.

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 bottom of the XEM8310. This design is realized in Altium CAD drawings in the corresponding breakout board which are available through Pins Downloads.

Heat Sink

An active (fan-based) heatsink is available as an add on to install on the FPGA for cooling. The fan enable can be controlled over the FrontPanel API. See the Device Settings documentation for more information.

The fansink is Radian part number FI27/1.3+Y+T725.

The fansink has a nominal operating voltage of 12 V and a recommended operating range of 10.8 V to 13.2 V. The fansink is powered directly by the external power supply connected to the XEM8310. It is recommended to keep the external supply voltage within this range whenever the fansink is enabled.
