So, some time ago I ordered a Mega 2560 clone (a clone, not a fake) and When I received it I was suprised to see the Arduino logo and the back nicely printed.
I followed this topic and pretty much everything lines up to say that it's a counterfeit except for one thing, the little proprietary gold component is here and looks just like the real one (maybe the number on it changes but I don't know about that)
Here are pictures of the thing, it was dark so I had to use my phone to get some good light
Other than that the board works just like it should and im happy with it but I wanted to show you that in case countereits start having the gold component that is made to spot counterfeits
Also, the Amazon link where I got it http://www.amazon.fr/gp/product/B00OPO44UE?psc=1&redirect=true&ref_=oh_aui_detailpage_o09_s00
You can easily see that it's honest about being a clone and not trying to sell a legitimate Arduino board.
