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

From [Framework’s knowledgebase](https://knowledgebase.frame.work/hdmi-expansion-card-generations-Sk7AQKUv2):

"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"
