There is no default password, you should just get right onto the console. If things go as they should, you will be presented with a root console to the Edison. The Base Block has power, TX, and RX LEDs on board so you can get some feedback from the hardware if things are working. Connect the micro USB labeled console on the Base Block breakout to your desktop Linux machine and check dmesg to see something like the below to discover where the console is. The console is a great place to start to see if the Edison is up and running. In this series, I will be using the SparkFun base block to power the Edison. You have to connect the Edison using its small header to something that can offer it power. The Edison does not come with an easy way to directly power it up. It is fairly straightforward to connect a small screen and drive it from the Edison using SPI if you need that sort of thing. Note that there is no HDMI or composite video on the Edison. So you might need to do some voltage level shifting if you need to talk to higher voltage components from the Edison. Unlike platforms such as Arduino which operate their GPIO and other pins at 5 or 3.3 volts, the Edison runs them at 1.8v. One example block that has no output is the OLED screen, because if you stacked another block above the screen you wouldn’t be able to see it anymore. Most blocks have an input header on one side and an output header on the other side so you can quickly stack blocks together to build a working creation.
Each block provides a specific feature such as an accelerometer, battery, or screen. SparkFun Electronics has created a collection of small break out boards for the Edison, called “Blocks” (Figure 2).

The Edison costs about $50, plus whatever base board you plan to power the Edison from.Īlthough the little header on the bottom of the Edison helps keep things tiny, it is not the easiest thing to deal with when prototyping. On the bottom of the machine is a small rectangular connector that breaks out GPIO pins, TWI, SPI, and other goodies and allows the Edison to get its power from somewhere.

The Intel Edison measures about 1×1.5 inches but packs a dual core Atom CPU, 1GB of RAM, 4GB of storage, dual band WiFi-n, and Bluetooth (Figure 1). It begs to be the brain of your next electronics tinkering project, with all the basics in a tiny package and an easy way to connect other things you might need. The Intel Edison is a physically tiny computer that draws a small amount of power and breaks out plenty of connections to allow it to interact with other electronics.
