Omega2 Pro



The Omega2 Pro IoT computer is the next generation of Onion’s Linux-based, WiFi development board and the most powerful IoT computer we’ve made yet. It is a standalone device – the processor, memory, gigabytes of storage, and Wi-Fi are all built-in, and it’s smaller than a breadboard, making it easier than ever to build connected hardware applications.


The Omega2 Pro is the next generation of the Omega2 and the most powerful IoT computer we’ve made yet. It is a standalone device – the processor, memory, gigabytes of storage, and Wi-Fi are all built-in, and it’s smaller than a breadboard.

The storage is pre-loaded with the OpenWrt embedded Linux distro, so getting started is as easy as plugging in a Micro USB cable for power and taking a few minutes to go through the browser-based setup wizard.

See the Omega2 Pro Guide for details on getting started and using your new Omega2 Pro!

  • Dimensions: 73 mm x 44 mm

A common theme we heard from our users of previous Omega iterations was that they felt constrained by storage space. The gigabytes of storage on the Omega2 Pro will allow you to build rich, modern applications, with plenty of space to hold libraries, assets, media, and more.

The Omega2 Pro is compatible with the entire ecosystem of Omega2 Expansions!


The Omega2 runs an Onion-customized version of the OpenWRT Linux operating system. 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:

  • C
  • C++
  • Python
  • NodeJS
  • Rust
  • Ruby
  • PHP
  • Perl
  • GoLang
  • Shell

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.


IoT is all about connectivity, and the Omega2 Pro specializes in Wi-Fi networking. The Wi-Fi interface can simultaneously host its own Wi-Fi access point and connect to existing Wi-Fi networks.

The addition of an Ethernet expansion board brings the Omega2 Pro into the world of wired networking as well.

Battery Manager for Portability and Back-up

An on-board battery management chip makes the Omega2 Pro compatible with LiPo batteries: they can be used as the main power source, and will be charged when the Omega is connected to USB power. Use a battery to make your project portable, or to act as a back-up power supply.

Commandline Access

The on-board USB-to-serial chip provides reliable, always-on access to the Omega’s commandline, which is invaluable for debugging. Alternatively, securely connect to the commandline through the local network using SSH.

Full-color Notification LED

Along with the system status and Wi-Fi status LEDs, there is a full-color LED driven by a hardware pulse width modulation (PWM) controller, so animations and transitions are always smooth.

Lots of I/O

The Omega2 Pro features extensive I/O – USB, Ethernet, I2C, UART, I2S, SPI, PWM, and GPIOs – making it easy to interface with other devices and components.

On top of that, it’s compatible with the existing ecosystem of plug-and-play Omega2 expansions to add functionality.

An Ideal IoT Computer

Since we first launched the original Omega in 2015, and later the Omega2, we’ve shipped tens of thousands of boards and listened carefully to the feedback from our users. The result is the Omega2 Pro, the latest iteration on our vision for an ideal IoT computer:

  • Efficient: Power efficient but has computing horse-power
  • Connected: Wi-Fi connectivity out of the box
  • Versatile: Linux-based with lots of hardware expansions
  • Compact: Easily embeddable form-factor
  • Portable: Built-in LiPo battery management
  • Scalable: Perfect for prototypes and production
