Mini-ITX-Micro-ATX-NEEWhat are the pros and cons for Mini-ITX and Micro-ATX for embedded and industrial applications?

For consumer desktop and enterprise applications, it’s almost a no brainer to go for a Micro-ATX or ATX. In embedded applications, things tend to lean more to the Mini-ITX side of things. Let’s take a look at why that may be.

The Case for Mini-ITX

For industrial and embedded applications, this is pretty much the workhorse of the motherboards. They are in the highest demand and as a result there is a large selection to choose from.

Some of the benefits of the Mini-ITX:

  • Higher variety of product
  • Higher demand makes for a longer lifecycle by embedded manufacturers
  • The small form factor is very convenient for a lot of embedded applications
  • Because they are more “strictly embedded” it is easier to find Mini-ITX boards with fanless and rugged specifications.

The Case for Micro-ATX

Micro-ATX is reasonably popular in the consumer desktop market. It allows for most of the benefits of an ATX board, with a few concessions to save for space. In the embedded market they are in less demand than the Mini-ITX. But the main benefit, by far, is the amount of space available by the form factor.

Some benefits of the Micro-ATX:

  • Greater expansion
  • If you have the space, its larger surface area and case can allow for more airflow
  • Ideal for high powered processors

Mini-ITX vs. Micro-ATX: The Verdict

The case for use of a mini-itx vs. a micro-itx is a balanced, however the main things to consider are the following:

When to choose a Micro-ATX:

If the space restrictions aren’t too strict, and there are no features specific to the mini-ITX form factor that you need, then the Micro ATX seems a sure bet, with its higher power and more expansion.

When to choose a Mini-ITX:

For applications with space or power restrictions, a fanless Mini-ITX board with an Atom processor should be your board of choice.

ATX vs. Micro ATXThe “golden egg” for most of technology runs along a very particular line of thought: make your device smaller without sacrificing its ability to process and render the necessary information for the user. The consumer side of technology grasped this mantra and ran with it. The processes that needed a standard sized computer five years ago can now be shrunk to a single embedded board.

With the modern trend of smartphones and tablets, it would seem that there is no longer a need for the outdated and oversized motherboard. But does this apply to the industrial sector? If we can replace them with newer, smaller and sometimes more efficient components, then what is the point of these legacy parts? In selecting between a large ATX vs. Micro ATX board, should the choice always be the latter? This conversation rages on and each side makes compelling arguments. Both standards can coexist because they each play a role. They fit certain needs perfectly, but also have their drawbacks.

ATX vs. Micro ATX: What Can a Few Inches Do?

ATX boards, the big brother of the Micro ATX standard, are considered workhorses in the computing world. They are very versatile motherboards and can be found in a multitude of places, ranging from high powered workstations, database/server architecture and even to communication centers. From an industrial perspective, Continue Reading…
