Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: RTL-11023. We're now selling the newest revision (R3) of the Arduino UNO. This page is for reference only.

Description: This is the same product as the Arduino Main Board. The difference is this version comes in fancy clamshell packaging meant for our distributors that need it. Regular customers are welcome to order, but we want to limit the amount of extra packaging finding its way into the trash heap. An Arduino quickstart guide is available!

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).

This is the new Arduino Uno. The Uno automatically selects the appropriate power supply (USB or external power). A great description of the new functionality can be found here (USB fuse protection, software reset, and much more!). Board comes fully assembled and tested with ATMega328 pre-loaded with bootloader. Please see the Arduino support forum for more information about this new board revision and bootloader.

Note: This is the Arduino Uno board in retail packaging. We now sell the Uno R3 as our retail Arduino Main Board but we have a few of these left in stock so we're selling them at a reduced price for a limited time. Get them while you can!

  • I just bought my Arduino yesterday at Microcenter. Great board but I have one complaint: the edges of the PCB are frayed and I got a mean set of fiberglass splinters from handling the board. It appears no one bothered to sand the edges down after the boards were sheared and assembled. I will have to sand down the edges myself.

    • I took a look at the edges on the Uno I bought at Microcenter this evening, and you’re right. These could really use a bit of finishing, for appearance if not safety. Until then, it’s safe enough to lift by the USB port and/or power jack.
      Interestingly, I found all of the SparkFun stuff over in the video game section at Microcenter (in Madison Heights). Strange product placement in my mind, but whatever. I ended up talking with about six people, customers and sales alike, about what the heck these little boards could really do. It is SO ENCOURAGING, to me personally, knowing that there really is interest out there in embedded system design, programming, and open-source hardware, and that it’s attracting such a large and diverse audience. It’s been a while since I’ve seen such interest first-hand, but it was welcomed nonetheless.
