omega2

Omega2 is a compact, Linux-based single-board computer designed for Internet of Things (IoT) applications, developed by Onion Corporation. It targets developers and hobbyists seeking a small, networked platform for prototyping and deploying connected devices.

The Omega2 runs an OpenWrt-derived Linux firmware and provides onboard wireless connectivity with integrated Wi-Fi. It is intended to be used headlessly, controlled through a web management interface, SSH, or a serial console. The board supports common IoT development workflows and can be extended with software packages available through the OpenWrt ecosystem, including languages such as Python, Lua, and Node.js via the package manager.

Hardware features and expansion are geared toward ease of use in embedded projects. The Omega2 is commonly paired with a separate docking accessory that adds additional interfaces such as USB, microSD storage, and extended GPIO possibilities. This modular approach allows developers to experiment with sensors, actuators, and other peripherals without adding a full desktop-like footprint.

Development and community support focus on practical IoT use cases, with documentation, tutorials, and example projects available from Onion and community sites. Users can build and deploy small, networked devices for home automation, data collection, or remote sensing, and then manage or update devices remotely through the Omega2’s firmware and docking ecosystem.

History and variants: Onion released the Omega2 in the mid-2010s as part of its OpenWrt-based IoT product line. The line includes multiple variants and docks designed to expand capabilities, while maintaining a focus on portability and low power consumption.
