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.
OMEGA2+ Onion Omega 2 Plus
The Omega2+ IoT computer is Onion’s Linux-based, WiFi development board designed to enable makers of all skill levels to build connected hardware applications.
The Omega2+ IoT computer is Onion’s Linux-based, WiFi development board designed to enable makers of all skill levels to build connected hardware applications. Plug in your Omega and it will boot the operating system right away, allowing you to develop in your favorite programming language, create web applications, and interface with a variety of hardware with minimal time and effort spent getting started.
At the Omega2+’s core is the MT7688 SoC that features a 580 MHz MIPS CPU, supports 2.4 GHz IEEE 802.11 b/g/n WiFi as well as 10M/100M wired ethernet network connectivity, and operates at 3.3V. The Omega2+ comes with 128MB of DDR2 DRAM memory and 32MB of on-board flash storage, double that of the Omega2! The storage space is expandable using the MicroSD card slot on the underside of the Omega2+.
The Omega was built to interact with other hardware, so it has a wide variety of hardware interfaces. It has dedicated pins for USB2.0 and Ethernet as well as 12 GPIO pins that can be controlled by the user. These GPIOs can support the I2C, UART, and SPI serial communication protocols.
The best part is that it’s tiny, measuring 1.7″ by 1″ it takes up minimal space in the project.
The Omega2+ runs an Onion-customized version of the LEDE (Linux Embedded Development Environment) Linux operating system, a distribution based on OpenWRT. Since there is a full Linux OS running on the Omega, users are not limited in their choice of programming language. Supported programming languages include:
The Omega’s OS comes equipped as a web server by default, so that other devices on the local network can interact with the Omega through a browser.
So what makes the Omega2+ an IoT Computer? It’s a combination of the following:
- Small form factor
- Power efficiency
- Processing, networking, and encryption capabilities
- Flexibility that comes from running a Linux OS
- Support for many programming languages and many simultaneous processes
The Omega2+ is powerful and flexible enough to be the brain of almost any IoT device.
Omega + Dock
For the best experience and most functionality, the Omega can be plugged directly into any of a number of Docks provided by Onion. All Docks can be powered with a regular Micro-USB cable and contain a regulator circuit to safely provide 3.3V to power the Omega, so plug it in and get started with your Omega with no worries.
Each Dock adds unique functionality to the Omega, including exposing the Omega’s GPIOs, supporting the plug and play Omega Expansions, provide USB connectivity, among other things.

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.
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 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.
