I have a deep interest in the trend towards an Internet of Things (IoT) and one aspect of that interest is in the actual devices, sensors, circuits, and code that runs on them. Over the past year I've been playing with the Arduino Uno, the Beaglebone Black (BBB), and the Raspberry Pi (RPi). Asking me which one I like the most is like asking which is my favourite between Windows Phone, iPhone, and Android. Fact is, I like them all, just for different reasons. And, today my shiny new Intel Galileo arrived.

Admittedly, I got this one more for work than for play, but so far I have been WAY more impressed with this board than I thought I would be. So I thought in this post I would mention a few of the features I am finding noteworthy. If you're looking to setup your new Galileo, I used the excellent SparkFun walkthrough, but it looks to be just a slightly easier-to-read version of the Getting Started Guide from Intel (PDF).

Easy code deployment & add-on shields

My favourite feature of the Arduino is how easy it is to deploy code to the board. Whether going straight to the board with USB or through an FTDI breakout like I use with my LilyPad, it's the click of a button in the development environment. And there are so many great libraries and code samples from Adafruit, SparkFun, and out in the wild, you can make these boards do just about anything when combined with the multitude of add-on shields.

The Galileo doesn't use the same exact development environment as the Arduino, but they both originate from the Processing development environment and will be immediately familiar with anyone who has done Arduino development. It's the same language (C), you assign pins the same way, and almost all Arduino code just works. The Galileo also has the same header pinouts as the Arduino Uno so, while I haven't tried it just yet, my NFC shield (along with the associated library) should work fine with with the Galileo. This is noteworthy!

Access to Linux & horsepower

What I really like about the BBB and the RPi is the ability to run Linux on the metal. I'm a big fan of node.js and Python and being able to run mini web APIs and package managers on such a small form factor (despite the security threats) just makes me smile inside.

The Galileo has a tiny build of Linux as its firmware/bootloader baked onto its 8Mb SPI flash memory that can be updated through the dev environment (yes, that's very cool). But if you want to run what they call "Big Linux" you just need a micro SD card between 1 and 32 Gb (not 4Gb like the other boards) - I'm using a 2Gb one. This was easy to set up and node.js and python are already installed in the image provided. Smiling on the inside ...

Oh, and if you don't have a micro SD card handy and still need a command line fix, no problem. Just upload a simple script and you'll be able to use a serial terminal to log into "Little Linux". This was also pretty easy.

Onboard ethernet & storage

While ethernet and micro SD storage are built-in on the BBB and RPi, to get it on my Arduino, I had to get this shield. Sure it works, but it increases the cost and the size of the form factor. Not so with the Galileo as both are built-in. Unfortunately, the Galileo doesn't have built-in wifi. The other boards don't have 802.11 built-in either, but they have plenty of extra normal-size USB ports and setting up wifi dongles was easy. The Galileo only has one micro USB port ... but it also has a mini PCI Express (mPCIe) bus on the bottom ... which can take one of these (that's right, wifi AND Bluetooth 4). Mine should arrive early next week :)

Wrap up

So it's early days, but it's looking like this board is giving me most of my favourite features of my existing boards and more. It would be nice if there were some good enclosures available, but I'll probably just 3D print one for the time being. I'm mostly interested in using it with Bluetooth 4 and the XBee modules that are on the way so I can explore some connectivity options. More on that later. Oh, and I also have a Touch Board on the way to explore conductive ink. More on that too.

Fun fun fun! Let me know if you have any questions.
