Ok...

Good Product Solid casing and sleek look

Très bon produit, livraison rapide. A utiliser des à des fins non frauduleuses. Facile à programmer même si cela demandes quelques connaissances en programmations.

Nice to do hands of enrollments

works as expected works fine with Aduino IDE and executes fine

super ! reçu très rapidement, et marche nikel, je recommande

as described

Easy to program either from platformio or arduino ide. Sometimes you will need to open the case to force a reset. Not difficult though. There are some pin pads to make it easier.

Very few info, and yet not correct. Otherwise very good stealth device, nobody would suspect, that this is not an USB flash. I would modify it with additional storage only if I know that is possible... Where can I find pinout for the 6 pins on board?
