Omega2 EXPANSION DOCK

Onion Omega2/+ EXPANSION DOCK

The Expansion Dock provides an easy way to power the Omega with any Micro USB cable and breaks out the Omega’s GPIO pins. You can use them to control external circuits or connect Expansion boards to extend the functionality of your Omega. It also comes with an on-board USB-to-serial chip that allows you to access the terminal directly from your computer.

The Expansion Dock is the perfect companion for the Omega, making it incredibly convenient and easy to use as well as exposing a variety of the Omega’s features. We strongly recommend getting a Dock for your Omega to get the best experience and most performance, functionality, and stability from your device.
