RETIRED PRODUCT - We've stopped stocking this product or it has been retired by the manufacturer and is no longer for sale. This page remains available for its resources and as a source of potential interest.

The Omega2 Pro is the next generation of the Omega2 and the most powerful IoT computer from Onion 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.

Battery Manager for Portability and Back-up

An onboard 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 onboard USB-to-serial chip provides reliable, always-on access to the Omega’s command line, which is invaluable for debugging. Alternatively, securely connect to the command line through the local network using SSH. Full-colour Notification LED

Full-Colour Notification LED

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

Lots of I/O Options

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.


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.
