SparkFun will be closed May 25, 2015 for Memorial Day. Orders placed after 2pm on Friday the 22nd will ship out on Tuesday. Thanks!
Description: 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!

Bought it to use as a test mule for my new designs, and have become hooked. Seriously, this thing is more useful than duct tape and WD40. Absolutely amazing, saved some cash from the Arduino website and got a real one, not some cheap knockoff. Thanks sparkfun!

It’s very good !!
I fell in love with it right when I opened the box. And SparkFun does a really good job on shipping. They shipped just a few hours after I order and it took pnly two days to deliver! I’m impressed!
ive ordered so many parts from amazon last month that arent coming for another month, and last minute i order the uno from you guys and i get it in less than a week, and it got shipped out within hours! it’s my first time ordering from you guys and i will continue to do so

I bought an R3 because I had read on arduino.cc that it would not suffer the reset on serial connection problem that other boards have. That does not seem to be the case, this board still resets itself as soon as I connect over the serial interface.
Hi, I haven’t heard of the R3 not resetting when terminal is opened. Actually from all of my use cases, I have found that it does reset. However, in doing a bit of research on this topic, I found a suggestion that may help you. It appears that if you place a 10μF capacitor between Reset and Ground it will prevent the auto reset permanently.
Works great. I’ll be ordering more boards in the future.
Best thing you can buy as an entry level for beginners. A lot of support and very easy to use. Cross platform IDE and very helpful forum. A very vast range of third party parts that fit perfectly.
Couldn’t buy a better product even if I wanted!
Very satisfied. If you haven’t bought one yet or you are still undecided, wait no more, just buy it. I promise you that you won’t regret it and you’ll find a lot of tutorials if you have no idea what to do with it.
I was able to make useable things for around the house.
Upon plugging it in, I get the popup message : “This board comes from an uncertified manufacturer….” I would like my money to support the original crew.
Hi, I’m sorry about this. The Uno and other “official” Arduino boards such as the Mega, are not manufactured by the original crew. The error you are seeing is the Arduino.cc crew bringing attention to the fact that your board was made by Arduino SRL. However, at this time, Arduino.cc is not manufacturing a Uno board of their own. We suggest the Arduino Pro and Pro minis from Sparkfun as they do pay a royalty from each item sold back to the Arduino team. Additionally, the RedBoard is a great alternative is you choose to not purchase Unos.
I am a computer teacher and I use this board in my class, I love it.
Sparkfun shipped it fast and the MCU as I call it rocks right on through it’s loop functions. I think this is were to start if you want to learn programming. Great little board that could? Thanks, sparkfun
Because my project progressed so fast and smoothly my partner wanted to implement it immediately!
Onto the next project!
This product is great; it is just about what I expected. I use it in conjunction with my raspberry pi to hook up lights, buttons, motors , etc. Only complaint I have is it does not come with the USB to hook it up. It is a standard printer cable.
This is the non-SMD Arduino Uno - R3 board. Exactly what I wanted … at a good sale price. Should have purchased ten more as same does everything that I expected it to.
I bought this (supposedly) Original Arduino board a few weeks ago and the Arduino IDE shows me that it is not a Certified board. It works fine, but I preferred to buy from SparkFun and not Amazon because I wanted a certified one!

The item itself is perfect. Great functionality and you can use it for anything. Just one warning…You will have to fight many many battles to get any functionality out of this on Windows 8. Even if you go through the ordeal to allow unsigned drivers, install drivers from different compatible technologies, you will not have consistent connectibility. Mac works fantastic. Any other windows, you’re set. Just be aware.
These things are great for little projects. I popped one of the Breadboard shields on it, and with one TMP36 and 3 wires (and a little programming) I was sending temperatures to my Computer through the USB cable. And I know many people have done much more complicated projects.
Works well, no issues. Good price, too. Thanks sparkfun!
Bought two and gave one to a 15 year old young lady who has taken off in her programming. I enjoy teaching young people and watching them excel. Both the units worked perfectly.
