ESP2 WROOM Case marking / Memory size
Posted: Fri Mar 19, 2021 10:57 am
I have two types of ESP2 WROOM-32E
One batch has marked XXOH32 another has XXOH28
One batch is a 4MB Memory, the other is 16MB.
I think theXXOH28 is the 16MB type but there are no other markings that identify them as different.
Where is the official information on Case Marking relating to this. I can't see it in the datasheet.
