What 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.
