The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328. It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
The Nano 3.0 has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega328 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with the Arduino software) provide a virtual com port to software on the computer. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. The RX and TX LEDs on the board will flash when data is being transmitted via the FTDI chip and USB connection to the computer (but not for serial communication on pins 0 and 1).

Seems to have counterfeit FTDI chips. Bought two, began receiving this error after an update:
stk500_getsync(): not in sync: resp=0x00
After a lot of research, I found that downgrading the driver works, and that it is due to a counterfeit FTDI chip on the board. now I see there is a Windows 8 upgrade that may make this impossible.
If it weren't for this, I'd have rated them 5 stars all across the board.Bought just one to trial as I've been a PIC assembler programmer for decades and wanted to check out the Arduino and its IDE. Had some problems, to cut a long story short the Nano A0 pin had a dry joint and would intermittently disconnect from the A0 header-pin and instead it would pick up the voltage from the adjacent A1 pin. Used it successfully by leaving A0 disconnected and using other pins instead. Not a brilliant first impression of Arduinos.
I bought one to evaluate. On arrival I found it has an intermittent connection from A0 to the header pin, when it happens to be disconnected it picks up the voltage on A1 instead.
Otherwise functions ok, no problems connecting to Windows 8, but don't think I'll buy any more from here. Phil_G.
www.singlechannel.co.ukperfeito para pequenos projetos...Okay - but to expensive. You will get cheaper ones at the www - roundabout 1,30 $ less........I feel sorry to buy this item as I spent one full day to try to upload sample sketch but I failed to at least communicate with it. I advise you not to buy it.works very well, I like the small size and the reset button, the price is just right, I have Arduino uno R3 units, but they are a bit big to put on a RC craft, so I use the UNO to write my program and work out the bugs, then send the finished program to the little nano, connect my wires and off we go! if the pins are in the way, I unsolder them and use 90 deg pins so I can mount the nano flat, try to keep it away from the RX, the clock on the nano may cause noise problems for the RX.The nano. Arduino for the s,all heartedFirst of all, I am not a huge Arduino fan because I think most boards in the family are overpriced for the performance. The one plus about the Arduino family is the good software library support. Having said that, the main reason I got my 4 Arduino Nanos is because the HK price finally makes it a great value, especially since I can get them from the US warehouse. The quality of these clones is great. Only caveat is that you may have to try re-connecting to USB several times before computer recognizes it, but I believe that's true of genuine Nanos too. I'll have to find a shorter cable and see if that improves things. Once it does connect, you can use the Arduino dev IDE w/o problems.I do not know if it was working before but it is always a good idea to burn the boot loader to Arduino if there are any problems. I am not sure if just a USB connection will burn it because I used an usbasp programming stick instead.
