What is it?

Onion Omega 2 is a $5 Linux computer with Wifi support. It is great for developing Internet of Things (IoT) applications. Unfortunately, the board cannot be powered directly as there is no option for USB power. Also, it uses 2 mm pitch headers which makes it impossible to use with a regular breadboard without any converter/expansion board. Even after powering the Omega 2, accessing the terminal should be done through wifi. All these problems make Omega 2 less easy to get started.

This expansion board addresses the above-mentioned issues with some additional features at a very low cost compared to the expansion boards available from Onion Website directly.
