Onion Power Dock
Compatible with all Omega Expansions. Extend the functionality of your Omega by connecting one of our plug and play Expansions.
The Power Dock 2 frees you from wires and allows you to take all of your Omega projects on the go! We strongly recommend getting a Dock for your Omega to get the best experience and most performance, functionality, and stability from your device.
Use any 3.7V LiPo battery (not included) to provide power to the Omega and all connected Expansions and USB devices. Display the battery’s charge level on four battery indicator LEDs as well as read it in the OS with a single command! When your battery is out of juice, plug a short Micro USB cable (8″ or less is recommended) and the Power Dock will charge the battery.
No battery? No problem! Without a battery connected, the Power Dock behaves almost like the Expansion Dock. You can provide power with a short Micro USB cable and the regulator circuits on the Dock will ensure the Omega always receives the stable 3.3V it needs to operate optimally. An on-board ADC allows the Omega to measure the voltage level of an attached LiPo battery, giving an idea of how much juice is left in the battery!
Note that the Power Dock does not have include USB-to-Serial chip, so you will need to use SSH or the Console over WiFi to connect to your Omega. See the links below on how to do this.
The Dock exposes several of the Omega’s features to the user:
- The Omega’s GPIOs are exposed on the Expansion Header. Use the header to plug in Onion Expansions or connect to external circuits
- Connect USB devices directly to your Omega
- Control the RGB LED on the Dock using the Omega’s GPIOs
- Press the Reset Button to reboot your Omega, hold it for 10 seconds to perform a factory restore
- Turn your Omega on and off with the Power Switch.

The Ethernet Expansion adds an Ethernet port to your Omega with a maximum connection speed of 100Mbps. While the Omega is all about wireless connectivity, a reliable wired network connection can be a great addition to a project, and the Ethernet Expansion is a great tool for quickly reflashing your Omega’s firmware.
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.
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 Relay Expansion enables your Omega to control two other, independent electrical circuits. The circuits are isolated from the Omega and can operate at much higher or lower voltages than the Omega. So you can control other circuits you’ve built or small household appliances rated up to 60W. This Expansion is perfect for home automation projects since it gives you the ability to control other devices remotely using your Omega.
