How to distinguish between 1st gen HDMI Expansion Cards and later revisions?

Are there any differences in markings? Tried looking on the marketplace but it makes no mention of SKU or anything.

From Framework’s knowledgebase:

"You can identify which generation of card you have by checking the part number printed on the back of the Expansion Card:

  • FRACCHBZ01 is the HDMI (1st Gen) Expansion Card
  • FRACCHBZ01-2 is the BETA HDMI (2nd Gen) Expansion Card
  • FRACCHBZ01-3 is the HDMI (3rd Gen) Expansion Card"
