This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.

The Uno R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The Uno R3 works with all existing shields but can adapt to new shields which use these additional pins.

Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).

Note: The Arduino Uno R3 requires the Arduino 1.0 drivers folder in order to install properly on some computers. We have tested and confirmed that the R3 can be programmed in older versions of the IDE. However, the first time using the R3 on a new computer, you will need to have Arduino 1.0 installed on that machine. If you are interested in reading more about the changes to the IDE, check out the official Arduino 1.0 Release notes!

I've been wanting a microcontroller

By: on 25 October 2017
I've been wanting a microcontroller and decided on this one. Let me tell you, this one is well worth the money. I found it to be reliable and I'm sure that it will last a long way down the road. I like other products by the company, so I guess this really shouldn't surprise me!

Great for learning C/C++ and physical computing

By: on 25 October 2017
This Arduino is great for learning C/C++ and physical computing. If an 8 year old child was precocious enough, they could probably figure it out on their own with little to no help. In addition to that, I have never been to a user forum (http://community.littlebirdelectronics.com) that is more helpful and friendly.

Pretty good board to learn programming

By: on 25 October 2017
I placed an order on Monday afternoon and received it on Tuesday morning. Thanks Little Bird! The Uno is good Arduino board to learn the basics of microcontroller programming. I'm looking forward to showing my kids how to use it. The board itself comes with no documentation but I was able to find a lot of help on the Little Bird / Arduino forums.

Well worth the money

By: on 25 October 2017
I've been wanting a real Arduino for a while (I have one of the cheap clones). Let me tell you, the official Arduino Uno is well worth the money. It is great to have an Arduino that "just works" and doesn't need special drivers. I found the Arduino to be reliable on Windows 10. The shipping was fast and I like the other gear Little Bird sells, so I guess this really shouldn't surprise me!
