"With the Omega2, we want to lower the barrier of entry, and allow everyone to take the leap into hardware development. We made the Omega2 tiny so that it can easily fit into your DIY project or commercial product. It is less than 1/4 the size of the Raspberry Pi, and less than 1/3 the size of the Arduino Uno."
