Almost every backplane-based embedded computing system in existence has a board that is considered the controller. Over the years, the industry has often used the term Single Board Computer (SBC) to describe that board. The term is used because all of the basic computer functionality is integrated onto that one board: microprocessor, memory, and I/O. The functionality of SBCs has evolved in step with the advancements made in computer technology, with both the performance and functional density increasing many-fold since the first boards were introduced in the mid 1980s.

The addition of general purpose I/O to both VME and PMC system buses has historically had its challenges: limitations in COTS I/O module diversity and insufficient slots for I/O. However, USB and Ethernet I/O options are effectively eliminating these hassles.
