Today, Arduino announced a new family of wireless products that combine the Arduino architecture with Linux. The Arduino  Yún is intended to be the first member of this new line of wifi products. Arduino expects the new board to bring the power of Linux with ease of use of Arduino.

From the Arduino Press Office, “Yún means ‘cloud’ in Chinese language as the purpose of this board to make it simple to connect to complex web services directly from Arduino.”

Developed in partnership with Boston-based automation engineers Dog Hunter, it’s basically a Leonardo (ATmega32U4) with an embedded wifi Linux board on the PCB, running Linino (MIPS Linux variant) to handle all those wordy text-based formats like XML and other HTTP transactions. You can program it via wifi, or by the usual USB cable. And they’ve also partnered with Temboo for one-stop API access to data from Twitter, Facebook, Foursquare, FedEx, PayPal, and many more.

For $69 plus tax you get:

Technical specifications

Arduino is on a roll at Maker Faire Bay Area. Friday they announced a new Arduino robot, today the Arduino Yún wifi board — now you’ve got us wondering about Sunday, Massimo …

    We’re putting the internet on things! And now we have things on the internet!

  3. Baxter says:

    I love the Arduino, but if I want Linux I can get a Raspberry Pi for less than half the price.

  4. Madox says:

    Might want to take a look at that confusing PoE compatible point…

  5. Dmitriy says:

    At that price it should have ARM, and more IO pins, IMO. As it is, WiFi chip probably has an order of magnitude more processing power than the microcontroller.

  6. says:

    For $70 wouldn’t one of those cheap android boards be a better deal? Much more resources and running linux on the main processor.

  7. Paul Beaudet says:

    I don’t think you folks really understand how cool this is. The raspberry pi doesn’t really lower the barrier to entry beyond price (no unified simplistic way to program and share) and you would have to add an Arduino or something else to it to do many more real time physically oriented projects. 35pi+35arduino=70…Except this comes in one package and works with the shields that I have!

  8. Ed says:

    This looks like a real win, as long as the Linux side is *very* accessible and hackable. >However<, I'm really disappointed that it's a 5V board. Most of the gizmos I'd be interested in connecting to it are 3.3V…keeping us in the wonderful world of level converters.

  9. Max Kingsbury says:

    A 16 MHz 8-bit micro running Linux? Sounds pretty damned underpowered.

    Also, next time you take fancy PR pictures, you should clean the PCB first. The flux looks nasty.

    1. Max Kingsbury says:

      Oops, I got confused about which part was running Linux. My bad.

      1. Paul Beaudet says:

        Maybe this was the 8-bit linux micro you were thinking of – 2 hours to boot FTW!

    With little steps Arduino will become one of the most powerful provider for robotic components and kits. This is great since they base on idea of open-source for all projects. As we can see there are some new products in the range of Arduino

  11. lp says:

    This board has the same CPU, flash,ram and architecture as Dragino ms14. Anyone know if there firmware is interchangeable?
