The XEM8305 PCB is 83mm x 53mm (3.27″ x 2.09″) with four mounting holes placed near the corners. These mounting holes are electrically isolated from all signals on the XEM8305. USB Type C is located along one edge of the PCB. Two 80-pin and one 100-pin expansion connectors are available on the bottom-side of the PCB. Power is connected through the expansion connectors.

Mating Board Diagram
Use the mating diagram below to orient and design peripheral mating hardware. This design is realized in Altium CAD drawings in the corresponding breakout board which are available through Pins Downloads.

An active (fan-based) heatsink is available as an add on to install on the FPGA for cooling. The XEM8305 is compatible with this clip on fansink, but it does not provide a power connector for the fan. Power for the fan must be provided by the carrier board.
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.
