Our Omega2 Eval Boards represent a new starting point for working with the Onion Omega2 modules. Designed to lower the friction of working with the Omega2, they’re indispensable for evaluation, early prototyping, and development. They also serve as a template to build your own custom board and can even be used as SBCs for your applications.

Almost all of the Omega’s capabilities and I/O are easily accessible with the Eval Boards: USB Type-C for power and serial access, Ethernet port, USB Type-A host port, MicroSD slot, and access to all available I/O pins.

Along with the Eval Boards, Onion is preparing new firmware based on the OpenWRT 23.05 release and running Linux kernel 5.15. The firmware is more modern, lighter weight, and easier to customize than before.

Get Started With Omega In Record Time

These devices drastically lower the friction of getting started with the Omega2 modules. They provide easy access to the vast majority of Omega’s capabilities in a compact form factor.

By providing access to all of the Omega’s capabilities, these Eval Boards can be used for almost every part of your project:

• Shorten the time between onboarding and hello world
• Development and testing
• Prototype your own solutions
• Use as a single board computer to implement and deploy a solution
• Use as a template for your own custom board designs

Features & Specifications

The Omega2 Eval Board includes the through-hole Omega2+ and a new 8-pin header (in addition to a traditional 30-pin header that’s backwards compatible with the existing Omega2 ecosystem). The Omega2S Eval Board includes an SMT Omega2S+ and a new 24-pin header (in addition to the traditional 30-pin header).

Open Source

The Omega2 and Omega2S Eval Board designs are open, and board schematics will be posted to our GitHub when the design is finalized. Our firmware and software are all open source and available on GitHub already. We have documentation on our website describing how to build it yourself from source.
