Need help identifying an FPGA board.

Looks like it might be one of these:

https://www.microsoft.com/en-us/research/project/project-catapult/

From the little reading Ive done, it's a propietary board used in the microsoft data centres, that academics can use to accelerate their work. You will likely need to apply to here: https://www.microsoft.com/en-us/research/academic-program/project-catapult-academic-program/ to have any chance of using the board yourself.

I suspect you wont get very far trying to use this board for your own purposes. I hope you didnt pay a lot for it (Statix V dev cards of this spec are ususally about $6000-7000)
