Arduino Yún

I am delighted to welcome Stefano Guglielmetti who, together with other Arduino friends/supporters, accepted to start experimenting with  Arduino Yun and write a blog post to present some hands-on results. Starting today we are going to host a series of guest bloggers exploring different unique features of our new board.

Stefano, has more than 16 years of experience in the Internet industry, working both with small companies and start-ups up to very big and complex environments. His post below was orginally published at this link.


Finally!!! Finally I put my hands on a brand new  Arduino Yún. I’ve been waiting for this a long, loooong time. I’ve been playing with Arduino since the “diecimila” model came out and I, as a lot of people, always suffered the lack of connectivity and of real computing power. I tried to solve some of these problems using RaspberryPi and/or Electric Imp, but I always missed the Arduino approach… easy, lots of shields and Arduino ready parts, a lot of documentation, a strong community and the freedom of Open Source.

Now one of my dreams came true, and every time I go deeper into the discovery of the Yún’s capabilities, I find something amazing, very smart and very well done.

I won’t describe the platform itself, as many articles talking about that are already published and there will be many more to come. I’ll start directly with a real life example, in just a few hours I finally built something really, really useful to me, something I already built several times in various ways but none of which really satisfied me.

The task is pretty simple, and I believe it will be very useful to many people: I need to be alerted in real time when I receive some important emails. Not all the emails: we provide customer care for many clients, with different SLAs, and I need to be alerted only for the most important ones. Moreover, sometimes I look forward to receiving a precise email… a shipment confirmation, a mail from a special someone… I need something flexible, eye catching, that doesn’t depend on my computer or my cellphone (that always has only 1% battery) (more…)

The Power of Temboo: connect the Yún to 100+ APIs

1 - Arduino Temboo schema

(Guest post by Temboo Team)

Ever wish your Arduino could respond to the weather on the other side of the world? Or send you an email to let you know what it’s up to? Upload stuff to your Dropbox account? Or detect if you’re at risk of exposure to toxic chemicals?

Now it can. The Arduino Yún can easily grab all sorts of data and interact with tons of web-based services like Fitbit, Facebook, and Google because every Yún comes loaded with the power of Temboo. Using the Yún’s built in wi-fI capabilities, Temboo makes it easy for the Yún to connect to over 100 Application Programming Interfaces (APIs).

Don’t know what an API is or how to use one? Don’t worry. You don’t need to. With Temboo you can start using APIs with your Yún in minutes. We’ve standardized how to program with them and made sure they play nice with Arduino. (more…)

It’s time to enjoy the Arduino Yún: now available for purchase!

Arduino Yún

We are extremely happy to announce the availability of the Arduino Yún in our store at the price of 69$/52€ (vat not included) and distributors worldwide.

The Arduino Yún is the combination of a classic Arduino Leonardo with a Wifi system-on-a-chip running Linino. It’s based on the ATMega32u4 microcontroller and on the Atheros AR9331 running Linino, a customized version of OpenWRT, the most used Linux distribution for embedded devices.

Alongside the new board, we are also releasing the new Arduino IDE Version 1.5.4 (available now for download) featuring support for Arduino Yún, some new features, and general bug fixes. The new features include:

  • Board recognition: every time you connect an Arduino board, the IDE recognizes the type of board you are working with
  • Memory: when you upload a sketch, the IDE tells you how much memory you are using
  • Copy Error button: you can more easily copy and paste errors to share them in the forum (more…)

Hands on: the Arduino Yún’s Bridge

Thursday, September 5th, 2013

arduino yun - handson

The other day, we gave you an overview of the Yún’s hardware. Today, we are going to talk about the Bridge library, describing how it facilitates communication between the two processors. The Arduino Yún has two different processors on-board: an Atheros AR9331 running Linino (a customized OpenWRT GNU/Linux distribution maintained by Dog Hunter) linked through its serial port with an Atmel ATMega32U4 (the same processor as the Leonardo).
The Bridge concerns itself with communication between these two parts of the Yún.

The Bridge is made of two different parts
One part, written in Python, runs on the GNU/Linux processor and has three functions:

  1. it executes programs on the GNU/Linux side, when asked by Arduino.
  2. it provides a shared storage space, useful for sharing data like sensor readings between the Arduino and the Internet
  3. it receives commands coming from the Internet and passes them directly to the Arduino

The other part of Bridge is the library that runs on the 32U4. The library allows you to access the Linino parts of Bridge through your sketches. (more…)

Let’s explore Arduino Yún’s unique features – Hardware review

Arduino Yún

As announced a few days ago, the newest addition to the Arduino family, the Arduino Yún, will be available starting September 10. This is the first in a series of posts that will describe some of the Yún’s unique features. Today, we’ll focus on the hardware.


The Yún is unique in the Arduino lineup, as it has a lightweight Linux distribution to complement the traditional microcontroller interface. It also has WiFi and Ethernet connections on board, enabling it to communicate with networks out of the box. The Yún’s Linux and Arduino processors communicate through the Bridge library, allowing Arduino sketches to send commands to the command line interface of Linux.

The Arduino Yún has the same footprint as an Arduino Uno but combines an ATmega32U4 microcontroller (the same as the Leonardo) and a Linux system based on the Atheros AR9331 chipset. Additionally, there are built-in Ethernet and WiFi capabilities. The combination of the classic Arduino programming experience and advanced internet capabilities afforded by a Linux system make the Yún a powerful tool for communicating with the internet of things.

The Yún’s layout keeps the I/O pins the same as the Arduino Leonardo. As such, the Yún is compatible with the most shields designed for Arduino.

With the Yún’s auto-discovery system, your computer can recognize boards connected to the same network. This enables you to upload sketches wirelessly to the Yún. You can still upload sketches to the Yún through the micro-USB connector just as you would with the Leonardo. (more…)

Updating about Arduino Yún (video preview!) and Arduino Robot

Arduino Yún - Unboxing

Some months ago we announced that we were developing a new product to meet the growing demand for wi-fi, linux based boards. The blogpost on the upcoming Arduino YÚN was our most read ever, and since then the attention has stayed high.

Recently, some of you have been asking why the YÚN hasn’t come out yet and why the Arduino Robot is not yet available for purchase.

Simply put, moving to a wifi-enabled linux board is a whole new step for Arduino and it’s taking longer than we expected. Arduino YÚN  is our most complex product ever and we decided to working on getting it right regardless of timing.

The early prototypes boards mounted 8MB of Flash and 32MB of RAM. While we managed to implement most of the YÚN features previously planned inside this amount of memory, we were forced to use optimized versions of the most common software packages: smaller in size but missing a lot of cool features available in the “full” non-optimized version.

We also quickly discovered that there wasn’t plenty of free space remaining for the user to install additional packages or to run complex programs without incurring in stability problems.

Considering this we finally decided to double both Flash and RAM, giving a comfortable 16MB of Flash and 64MB of RAM.

We try our best to get everything done as soon as possible while still providing the quality that we hope distinguishes Arduino products.

The delay in the Arduino Robot is connected to that of YÚN and our distribution processes.

We are really happy about the new Arduino YÚN and we hope the community will be as well.

The board is going to be available on the Arduino Store from September the 10th, while being delivered to our distributors late this month. In the video below you can watch a  preview of the board with me and David Cuartielles giving some more details about it.


From the product pages on the Arduino Store,  for the YÚN and Robot, you can activate an alert that will send you an email when the product is available from the distributors.
