Arduino Team Offers Details on the Yún

Arduino Team Offers Details on the Yún

Arduino’s upcoming board, the Yún, is like an Arduino Leonardo and a Linux-based WiFi router packed onto one board. With its release about a week away, The Arduino team is starting to offer details on the hardware and how it all works together. Like the Leonardo, the Yún has an ATmega32U4 chip which can even be programmed via USB, just like the Leonardo.

However, the killer feature of the Yún is the Atheros AR9331 chip, which runs the Linux side of the board. But how does it work with the 32U4? According to the team, “the serial port of the AR9331 exposes the Linux console (aka, the command line interface, or CLI) for communication with the 32U4.” You can even program the board via WiFi. “The ATmega32U4 can be programmed from the AR9331 by uploading a sketch through the Yún’s WiFi interface. When connected to the same WiFi network as your computer, the board will appear under the “Port” menu of the Arduino IDE. The sketch will be transferred to the AR9331, and the Linux distribution will program the ATmega32U4 through the SPI bus, emulating an AVR ISP programmer.”

The board also has a USB host port, which allows you to connect computer peripherals like flash memory drives, keyboards, mice, joysticks, and webcams to the AR9331 chip.

Of course, we’ll be keeping a close eye on the Arduino Yún and are eager to see what can be done with it!

    Neato! But isn’t this getting a bit complicated? Bring back the Arduino Duemilanove!

      Hopefully, there will always be a nice variety of Arduino boards to choose from. I think the Uno (and its future descendants) will be around for a while to hold up the basic side of the Arduino product line.

  2. RAM says:

    Is there any price yet for the Yun?

    1. RAM says:

      Never mind, the next article says it could be $69

        Is it not costly… I can get 2 Pi’s for that price.. Anyways Arduino’s are a different beast …..

  3. computer repair says:

    I am just a newbies on Arduino. Is the Arduino Yun using same IDE ? Or, we need to learn Linux programming language?

    1. Arduino Team Offers Details on the Yún Matt Richardson says:

      The Yún uses the same IDE (just a newer version of it). The IDE can upload to the board via USB (just as it does with the traditional boards) or via Wifi.
