Miniboards are Multi-functional Single Board Computers that are ideal for using as Embedded Controllers.

There are two Industry Standard formats reflecting the size of the boards namely 3.5" and 5.25".

When selecting which Miniboard is suitable for the application the first decision to be made is which size of board to use - this may be dictated by physical constraints. The next important criteria is the type of processor chip needed to run the software application, once again bearing in mind key issues such environment (power dissipation / cooling) and space.

Following this, assuming there is still a multiple choice of boards, it very much depends on the I/O functionality required to interface the application to external equipment.
