Nano V3.0 for Arduino (Works with Official Arduino Boards)

Pros: It's an Arduino Nano V3.0 and it's cheap as, come with a usb cable and is almost plug'n'play. Got mine up and running pretty quickly considering it's my 1st Arduino ever.

Cons: Packaging was a but light and one pin was a little bent, but not a major issue. Finding the right usb drivers was the only hickup I had and managed to find the correct ones for my win7 64bit os after working through the support information on http://arduino.cc/en/Guide/Windows#toc4

Other: I'm really happy with this device and I put together a nice kit for the Nano from other DX items.

Pros: It's fully hw compatible with http://arduino.cc/en/Main/ArduinoBoardNano and have a good price. You can use all capabilities that provide arduino platform. Nano version of arduino have a really small size (is suitable for standard 48PIN CHIP socket). If you need a full size arduino - use SKU 66909.

Cons: It haven't ICSP connector but it isn't need for most users

Other: If you are really need arduino - it's good product for you.

Pros: If you want to start using microcontrollers, this is board for you.
And even if you are experienced user, with Nano you can build circuits around it without to much components.
Simple to connect, development software is free and open source.
And DX offers it at very reasonable price. In my country price is three to four times higher.

Cons: There's onboard regulator from 12V to 5V, which is obviously the worst part of this item.
I bought four of them. Regulator doesn't work on one from beginnig, on the other died after 15 minutes, while on other two works as it should. (check Discussions).
But if you will use it on 5 volts, this is not big Con anyway.

Other: I used to play with Z80 (difficult to use, complicated IO), 8031 (needs external EPROM), some PICs(simmilar as AVR) and AVRs(same uP family, as used here).
Based on my experiences i can tell you that Nano is the simplest way to add microcontrolling to any circuit.

Pros: It's cheap, well constructed, and works just as it should.

Cons: Is labelled "Arduino". Guys -- it's open source. The only thing you CAN'T do is call it "Arduino".

Other: It's a great deal as are some of the other accessories. Get them labelled "ArDXino" and everyone would be happy. (but also say "Arduino compatible" so they're easy to search for)

Pros: Cheapest Arduino I could find
Got basic programs up and running quickly using the Arduino software (http://arduino.cc/en/Main/Software)
Easy to program
Built in LED and reset switch

Cons: Was a little fiddly to setup and get the drivers working, but a reboot afterwards and running the dev software as an administrator sorted out all the issues.

Other: Excellent value, worked instantly with a 1602 LCD display on Windows 7 x64. Surprised at how easy it was to set up, connect and program.
Have to run the development software as an Administrator to get it to upload properly, but this is a Windows issue.
Great for a quick and cheap introduction to Arduino programming and prototyping, enough features/IO ports to keep an beginner like myself entertained.

Pros: Cheap, works.

Cons: Soldering on the CPU is a bit on the light side and there are solder balls on the CPU side as well so it's worth doing a visual of the board with an eye piece before using. I bought 2 of these and both had the above. No shorts but I personally dislike solder balls floating around.

Other: I'm very happy with this product. If only DX stocked Netduino products!

Pros: Nice circuit, it's cheap anf usefull for a lot of projects.
Very easy to start
It is really small
Plug an play; windows finds all the drivers for it
It works on USB power source no externar source is needed
A lot of documentation aviable in the net as it si an opensource circuit

Cons: It comes with a pin bent, so it must be protected simply with a foam or something
The pins marking is comfusing; in the official webpage of arduino nado there is other circuit with more readable characters

Other: Nice circuit for starting to use arduino or for a small layout.

Pros: This Arduino Nano clone is among the cheapest I have found, it's reasonable well built, the voltage regulator on mine seems to work (I've tried powering it using a 9V battery connected to VIN and GND with success).
Combining this with all the standard pros of the Nano (small size, lots of pins etc) and we have a winner

Cons: The NAME! Seriously DX, don't screw Arduino over by misusing their name. Rename this Nano to DXuino or something similar and add the text "Arduino compatible". This way I can continue buying this product without feeling like a crook.
The pin labels are a bit cramped together, sometimes making them hard to read, this is not the case on the real Arduino Nano manufactured by Gravitech where the text is much easier to read.
The packaging was sub par in my opinion, it was delivered in a zip bag without any kind of protection for the pins which could easily have been bent during shipping.

Other: Cheap, useful Arduino clone, with a name that should be changed ASAP. Some problems with the voltage regulator have been reported but mine worked. Will buy again if the name is updated.

Pros: The board was a bit smaller than I expected, which is only good. Soldering quality was very good. Liked the fact that a USB cable was supplied. At moments like this it is a Plus that the board is fed from the USB so I could go testing immediately.
Nicely fits in a breadboard that formed a good basis. Windows took a bit long to install the USB and serial drivers, but the board was recognized without problems.
Initially I had the dreaded "avrdude: stk500_getsync(): not in sync" error message, but apparently where I initially only saw one com port available in teh arduino software, a bit later a second one had appeared (COM45). Selecting that one solved the problem.
The Nano worked perfectly after that, at least.... in its functionality that I tested

Cons: Actually, no, I cannot think of any 'con'. The fact that it is labeleld as 'Arduino' instead of 'Dxuin compatible with Arduino' I really could care less about.
Maybe another con is that I will apend a lot of time playing with this thing :-)
And maybe, t would have been nice if there wld have been an ISP connector attached in the space that has been left open for it

Other: If you are into arduino, buy one, buy two. Why on earth wld I want to build my own 'freeduino' or 'barebones arduino' if I can get a fully functional board for this price.
This is a buy I certainly will not regret

Pros: Cheap, and compatible! Hooked it to my desktop, installed the debian arduio sdk, and had it blinking in under 5 minutes. works just like my arduino uno, (except its much smaller)

Cons: really none, some of the silkscreaning is a little rough, and as others have said, arduino is a brand name, and likely this is a ripped product, but as long as you think of it as a compatible one, not the name brand your ok.

Other: get it if oyu need a small formfactor arduino, or if oyu already have breadboards and dont want to buy shields.
