Onion

The Onion Omega can be thought of as something half way between an Arduino and a Raspberry Pi. It is small, sips power compared to its bigger brothers, and takes some of the benefits of both ends of the spectrum to make a compromise in the middle. Like the Pi, the Onion runs a Linux operating system – in this case, a slimed down version of OpenWRT called Onion OS. Unlike the Pi, you don’t get a desktop environment – just serial / SSH and the command line. Like the Arduino, you have low power consumption and mobility, but unlike the Arduino there is an operating system, WiFi, and a full TCP/IP stack with SSL/TLS with all the scripting/programming language support that you expect. Perfect for your next Internet of Things project!
