Same microprocessor than Arduino Uno. I believe it has a few little differences, but in general this is great for DIY projects where you need something small. The pins match perfectly a protoboard, so it can be used for quick prototyping very easily. Packaging was very good (sealed anti-static bag with foam protection inside). I only regret that I only bought 2 of these units ;).

This is nice beginner friendly Arduino nano. Pins are already soldered on it. If you want to solder pins yourself, or don't need pins soldered at all, you should get this one instead: http://bit.ly/2vFFjxu
