The Onion Omega family of single-board computers (SBCs) has carved a niche for itself in the world of embedded systems and IoT development. Known for their affordability, ease of use, and robust community support, these tiny computers pack a surprising punch. This article focuses on the Onion Omega1 Rev and its siblings, providing a comprehensive overview of their features, applications, and importantly, where to buy them. While the Omega1 Rev itself is no longer actively produced, understanding its legacy helps contextualize the current Omega2 range and their capabilities.
The Legacy of the Onion Omega1 Rev:
While the Onion Omega1 Rev is no longer actively sold by Onion Corporation, understanding its contribution is crucial. It was a pivotal product in establishing Onion's reputation for delivering powerful, yet affordable SBCs. Its compact size and relatively low power consumption made it ideal for various embedded applications. It served as a stepping stone for many developers entering the world of IoT and embedded systems, paving the way for the more advanced Omega2 series. Though discontinued, you may still find some units available through secondary marketplaces, but purchasing a newer Omega2 model is generally recommended due to improved specifications and ongoing support.
The Current Onion Omega2 Lineup: Your Buying Guide
Onion Corporation has moved beyond the Omega1 Rev, focusing its efforts on the Omega2 series. This range offers significant upgrades in processing power, connectivity options, and overall performance. Let's explore the current models available:
1. Omega2 Dash ($69.00): The budget-friendly powerhouse
The Omega2 Dash represents excellent value for money. It's a fantastic entry point for beginners and experienced developers alike. Its compact form factor and robust capabilities make it suitable for a wide range of projects. While specifications are slightly less powerful than its siblings, it still offers ample processing power for many IoT applications.
How to Buy: The Omega2 Dash, along with other Onion products, can be purchased directly from the official Onion Corporation store (detailed below). You may also find authorized resellers listed on their website.
