The Proto Expansion for the Onion Omega allows you to create your very own Expansion that interfaces with your Omega. It provides a small soldering area and 30-pin header that plugs into the Expansion Dock. With it you will have full control over what kind of project you design for your Omega.

Note: This Expansion requires a Dock with an Expansion Header to use, such as the Expansion Dock, Power Dock, or Arduino Dock R2.
