Hi, friends :slight_smile:

Some days ago I bought one piece of Arduino UNO Board and I am very satisfied with it ! Very good product.

After it today I bought the other piece (same one) from the same distributor, but both looks completely different.

To have a possibility to show You a big photos, I made a simple web page with them. Under detail pages are link for open an original picture (big
resolution).

Please, be so kind and check there and write me, if are both boards genuine OR if some of them is fake.

I tried to check there against picture on this website, but displayed UNO are not the same as mine ...

Thanks in advance. I some of them is fake, I must to contact the seller a return this.

Look genuine to me. The R3 has gone through at least one silkscreen change which would explain the differences between the two boards.

I have an R3 that is a perfect match to this board...

Your board on the left with all the connections looks like the current R3...

You now know all I know about the layouts.

As far as I can tell that page (The Arduino one) shows all the hardware variations. I imagine that the printing changes to try and combat the counterfeiters.
