ZinggJM:
What you seem to have is a Electronic Shelf Label.
How did you get it? Is this item missing somewhere?
Jean-Marc Zingg
This is not an Electronic Shelf Label, there is no radio or infrared receiver.
It is a preprogrammed advertising label that always displays the same rotating message (under 3.3V) for an article.
As the article was modified, the commercial change the advertissing label by an other displaying a new rotating message. He wanted to discard this one that I disassembled for maybe reuse.
