Black magic Thunderbolt 2 devices Enquiry

If I have old Blackmagic capturer device with thunder port 2 and my pc have only thunderpolt 3 can I found any converter from thunderpolt 2 to thunderpolt 3 ?

Your text is not all that clear...... you mean a card (PCI) or device/box ?
Please be clear, otherwise they think you are a spammer.

I gues you have the Ultrastudio mini with TB2 port. And i guess you have a new macbook with TB3 port?? Would have been easier to have these things summed up in your post.

But if so. Buy a TB3 to TB2 adapter cable from Apple and you are good to go.
