1.0 out of 5 stars Counterfeit board. DO NOT BUY!!!
By Shelly Hockett on July 14, 2015
Board is clearly counterfeit when compared against the official ones on arduino.cc. They have a section for identifying counterfeit boards, and this board is junk. While I understand that arduino is an open source thing, printing arduino.cc on the back (to look official) and delivering substandard parts is bullcrap. I paid a premium for the official board, and it was NOT delivered. Things to note in the photographs: The "A" in arduino is filled in, the font (especially the "O") in Uno is different, and Italy has no detail to it. All are pointing to an inferior product, and being counterfeit by the official site.

5.0 out of 5 stars It is the real Arduino Uno R3
By W. Mayhew on October 31, 2020
I purchased this genuine Arduino Uno R3. What more can I write? You know this board is going to work well with the Arduino Integrated Development Environment (IDE) software because this board is from the originators of Arduino. The latest versions of the R3 dropped the little map of Italy from the silk screen artwork on the board, but there is a hologram on the box that would probably be difficult to counterfeit. The genuine Arduino costs a little more, but you know it is going to work and you won’t be wasting time trouble shooting your project due to a junky clone board instead a fault in your code. Some of your purchase price is also going to support future Arduino development instead of just landing in someone’s pocket.

The attached photos show what you’ll receive in the box and a close-up of the authenticity hologram.

5.0 out of 5 stars Fun and Flexible to use
By Papa Bear on April 17, 2021
I'm a newbie to the world of Arduino, so I am very limited in what I can do with the Uno. I recently made my wife a plant self-watering system. It was fun and practical. I would highly recommend the true Arduino board (there are Chinese knockoffs) as they are better built and have the nice plastic tray it sits in so the solder points on the underside are disturbed. That's important to keep it from getting damaged.
If you're new to Arduino, I'd recommend watching lots of YouTube videos about how it works. The actual device does not come with any explanations for either how the two power ports work or any of the analog or digital inputs.
Doing simple projects are a great way to start in the world of micro electronic projects.
Enjoy!

5.0 out of 5 stars Arduino originale
Reviewed in Italy on April 21, 2019
bhe!!! Arduino originale è tutta un'altra cosa, a partire dalla confezione in cui arriva, curata nei minimi particolari, sicuramente costa un pochino di più rispetto ai suoi cloni, ma li vale tutti, al suo interno troviamo la scheda Arduino con un suo comodissimo e utile porta scheda in plexliglass che io personalmente ho trovato utilissima, in quanto evita di mandare in corto (accidentalmente) la scheda, ben fatta, il pc la riconosce subito senza problemi, non che le altre marche non vengano riconosciute ma Arduino originale ha qualcosa in più :-). la uso con la shield v3 e grbl è fantastica.
Straconsigliata
