The XEM8320 board does not have an FMC HPC connector. Would the XEM8310 board have this connector?
The XEM8310 has expansion connectors as noted here: Expansion Connectors - Opal Kelly Documentation Portal. This way, a custom breakout board could be designed to a customer’s specification. So, to answer your question, the XEM8310 does not have an FMC HPC connector by default. However, a breakout board that mates with the XEM8310 could be designed to include such a connector.
Hope this helps!
