How we Picked the Best Single-board Computer SBC
Over the past decade we’ve seen a number of single-board computers enter the market at a variety of price points, capabilities and features. There’s also been strong interest in SBCs for a variety of applications from Industrial to Consumer. We looked at a wide range of SBCs – analyzed a number of different factors to include key specifications, price and made our top picks. Here is a list of what we considered:
Modern applications require more and more horsepower. It’s the one thing that we can’t have too much of. And the other is RAM.
If the SBC needs to fit into an enclosure or embedded into a system, the form factor will be one of the major considerations.
SBCs with both wired and wireless connectivity options will find a larger range of applications than those limited to either of the two.
One the benefits of SBCs is that they are available at multiple price points, from the beginner level user just starting their journey to the advanced level user who will use the SBC for a very specific application.
A larger community means better support. It could also mean the difference between a SBC being used and a SBC which is discarded because a solution to the problem(s) being faced can’t be found.
The Future of Single-board computers
There’s growing interest in SBCs for a variety of applications. In general there is a trend toward smaller size and more intensive processing of larger amounts of data. All this at lower price points to allow SBCs to be included in more products.
Single board computers or SBCs are the modern do-it-all. They are available with different features and suit beginners and advanced users. Based on detailed research and analysis here are our top picks:
- The Best Single Board Computer: ODYSSEY x86 Mini-PC
- Runner-up: Asus Tinker Board S
- Best for Artificial Intelligence Applications: NVIDIA Jetson TX2
