Compare this board to a pcDuino from LinkSprite and you will see that the YUN is inferior in all ways. Pick your criteria, price, HDMI graphics out, RAM, Flash, Ubuntu release stability, USB ports, Wifi etc… Don’t buy this board until you do the comparison. I’m using pcDuinos in a product I sell. Its better than RPI too as it has an arduino shield socket.

This is a great board with a rock solid Linux Distro, great Ubuntu repository to get whatever apps you want, has a nice inexpensive enclosure available for it, HD graphics and performance as good as any netbook. I use it as an arduino host computer/development system and as a gateway for my CS3 XBee networks. http://126.96.36.199//cs3prod.htm I have 5 of them running as gateways for 8 months now and they never miss a beat. I’ve tried Raspberry Pi, CubieTruck, Lenovo Q150 and even Intel Galileo and none of them come close. It doesn’t run arduino sketches itself but it does run standard C++ and Python code which can control the arduino pins on the board. It does run the arduino IDE and provide download to USB attached arduino boards. 4GB version is out of fab and due soon I’ve heard.

I’m mostly interested in arduino compatible boards for battery/solar powered wireless monitoring outdoors so the first thing I did was plug in an arduino wireless shield with an XBee 900HP radio on board into the Galileo. Picture at http://188.8.131.52/news2.htm It took a day and a half to get it working but, it works well. I was able to integrate the data packet stream coming from my sketch running on the Galileo with my XBee CS3 gateway and web server where I can view the data, just battery voltages at this point. Battery life of 4 AA batteries powering the node was about 3 hours corresponding to about 350mA current draw on average, very high for an arduino board.
The Galileo fits in an odd place somewhere between low cost Linux computers like pcDuino/Raspberry Pi and arduino boards like Uno and Mega2560. It costs more,and has no graphics output like the Linux machines and uses way too much power to be a battery powered arduino based device. The most interesting feature of Galileo is that it can access openCV functionality from an arduino sketch. The way this functionality is accessed still needs work though. You have to use an arduino-Galileo extention system() call to pass data and run a linux program you have written and compiled on the SD card separately which uses openCV and then read the results back into your arduino sketch using some file manipulation calls that Intel added to their version of the arduino language. fopen(), fget()…etc. If Intel were to create an openCV standard arduino library that would be a very special feature. That plus a camera shield would make a great vision platform which would fully utilize the Gallileo’s Quark processor performance.

Digi no longer recommends this product. It has been superseded by their 900HP product which I can say first hand is an excellent product, especially its Digimesh networking. I have 20 of these nodes in the field for 6 months now spread out over 500 acres and they work very robustly. There is no question the 900HP is worth the extra $3. Mark Holler, Camalie Networks.
