out of curiosity i downloaded the real data sheet and discovered quite a few things

1 the bus speed is 100khz
2 the datasheet depicts an abnormally long repeated start signal on a read transaction [no specs but]
3 the bus needs a SMBus Request signal before a read/write transaction
4 the genuine article has addr 0 not 0xb4

looking at ebay banggood aliexpress etc yields a 5 to 1 price range from $10 to nearly $60 us
most venders spruking a multitude of part numbers in the listing, you would wonder what you are buying
i suspect clones fakes and lookalikes abound

a real one from e14 or rs is $40ish au , a bit much for a play trinket for me
so i don't think i can take it much further
