Opal Kelly Pins is an interactive online reference for the expansion connectors on all Opal Kelly FPGA integration modules. It provides additional information on pin capabilities, pin characteristics, and PCB routing.

Pins can also generate constraint files (XDC) and help you map your HDL net names to FPGA pin locations automatically.

The Pins reference for the XEM8320 may be found at the link to the right.
