I am not sure yet, whether the chip is identical or different compared to the one I received earlier. At least the description on the chip on the picture is different than what I received (and what I expected). Perhaps they're identical inside, but not the outside.
An update on the boards. Although the engraved description on the received chips was different than I had expected, they appear to behave similar as the ones on the sales photograph. I was unlucky to have 1 faulty board, but the service and communication of this company is good, so this shop is definitely a recommendation.
Goods arrived in good condition
