I thought I was ordering an Arduino/gravitech Nano, but when it arrived several weeks after the order, i see that it came from shenzhen, china. I think Amazon should declare their nano is a knockoff, and not an Arduino/gravitech unit. The chinese Nano didn't last long. It ran for about an hour. With multimeter, Vin showed only 0.015 v ?, and eventually 5v (pin 27) dropped to 2.6v and the PC would no longer recognize the USB port. Useless.

I have a real Gravitech nano that works just fine.

I will notify Gravitech and Arduino of the misleading advertising

Though Arduino makes its circuits and board layouts available as open source items for anyone to use, this board is a knock-off, made in China, but labeled as "ARDUINO NANO v3.0". This is a violation of Arduino's request that people not use their name.

That said, the board works fine, and is nicely made. I will use it and be happy with it, but I am sorry these folks don't observe Arduino's simple rules.

I am new to Arduino, but I dove right in! I was looking for a small USB-enabled board that would work well as an LED controller for a quadcopter that I am building. I was so eager to get started that after finishing my purchase for this board on Amazon, I went directly to RadioShack to buy one so that I did not have to wait. RadioShack only had the Arduino Micro, and I was then curious to see which was smaller. The Nano is smaller, but only by about 5mm in length.

My title ends with "but" because when I received the board, some pins were bent and I noticed RIGHT AWAY that it was not a Gravitech board. The board I received looks a bit different than the one pictured, but I assume it functions exactly the same. The Micro has 4 extra pins, labeled "MOSI", "SS", "MI" and "SCK" -- not sure what these are, but I haven't used them yet.

Here are a few comparisons of the Nano vs the Micro:

Nano:
Manufactured by Xinda (mine was, anyhow)
30 pins
Mini-USB
VERY SMALL (and hard to press) reset button
5mm shorter than Micro
Atmega328P
Pin labeling and LED labeling are kinda crammed and hard to decipher
Power LED on top (green)
Weighs in at just over 6 grams (6g)

Micro:
Designed with Adafruit
34 pins
Micro-USB
Decent sized reset button
5mm longer than Nano
Atmega32u4
Pins are clearly labeled and easy to read
Power LED on bottom (blue)
Weighs in at just under 7 grams (7g)

Both boards are breadboard friendly, have 4 integrated LEDs (L, TX, RX, PWR). Overall, I like the Micro better than the Nano, but mainly because I don't keep a mini USB cable plugged into my PC at all times (and it's a wee bit prettier...) Both boards seem to be directly interchangeable, with the exception of the 4 additional pins on the ISP header-side of the Micro board.

Just a side note: I might switch to an Arduino Pro Mini once I get the custom x550 quadcopter finished, since it is about 4 grams (4g) lighter than the Nano and Micro.

Could be a defective unit, one of problem, but this thing quit working almost immediately. My Arduino Uno has worked without issue for months. The Nano quick working in a few days.

Was not syncing up with my computer. Would appear to be initialized on some computers but not others. Nothing but problems. I bought this for a school project and am receiving an extremely low grade because of this. I would not buy this product. It is not even even Arduino it's some knock off called Funduino. Very unsatisfied.

It isn't genuine italian arduino as shown in the pictures. I've got a fake board with very low quality. Don't buy here.

As others have stated, it is advertised as Arduino but is clearly a knockoff. One works 'fine,' the other does not communicate, despite my attempts to reburn the bootloader. Oh well, it was cheap.

Be careful when you see a good deal.. I bought this a few months back and only got around to toying with it last weekend. I expected an Arduino Nano but this was clearly a clone that uses the Arduino name (shameful considering that this open design only asks that companies like this DO NOT market as "Arduino").. But these Chinese manufacturers clearly have no honor.

That being said, I was excited for a single day as I eagerly wired up a new project.. It was immediately recognized by my computer and I was able to upload my sketch... I worked happily for a few hours tweaking my code and had no issues at first.

The fun didn't last... First it stopped being detected by my computer.. I left it be for a while (out of frustration) when I came back it was getting power and still not communicating.. I went to bed.. next morning all I get is a lit LED..

Sadly, I consider this think to be dead and gone.. Switched over to my Arduino UNO and having no problems..

Buyer beware the clone!

UPDATE: I'm not changing the rating because I don't like to be mislead, however I was able to get this board working again by powering the VIN with 9 volts then plugging the USB into my computer.

This is an Arduino with an ATmega328 processor on a small surface mount board. The board has pin headers that will fit a 600-mil 24-pin socket. Interconnect and power is supplied through a mini-USB connector.

The board has pinouts and physical connections that make it mostly compatible with a Basic Stamp processor. However, this is not a drop in replacement for a Basic Stamp. Whether this part can be used to replace the stamp depends a great deal on the application. In particular, you should carefully evaluate the power requirements and I/O current requirements of the Nano versus the Basic Stamp.

On the plus side - and I consider this to be a huge plus - this board comes complete with the entire Arduino ecosystem of development tools, prototyping kits, software, and libraries. Chances are, if you want code, someone has already written something close to what you need. Because the Arduino environment is entirely open, there are no proprietary barriers to using this product. The development suite is excellent, complete and effective, and the price (free) is hard to beat.

All in all, I use this product, and highly recommend it.

Great build quality. Pretty sparkly blue PCB. Really great design.

My only complaint is that for whatever reason, mine came without the 6-pin ISP header. Luckily I work for an electronics company and I have easy access to many, but I feel that I was misled by the product description.
