WebOct 5, 2014 · So I yanked mfrc522 chip out and redid some circuit pathing under it. reflowed, put 1.8v to pin #2(PVDD) 3.3v elsewhere. And the result was exactly the same. Does somebody have more experience with datasheets and can say if my assumption to supply 1.8v to PVDD to get 1.8v level io was correct?
