357: 186: 620:. A single-board configuration reduces a system's overall cost, by reducing the number of circuit boards required, and by eliminating connectors and bus driver circuits that would otherwise be used. By putting all the functions on one board, a smaller overall system can be obtained, for example, as in notebook computers. Connectors are a frequent source of reliability problems, so a single-board system eliminates these problems. 235: 2435: 84: 43: 605: 596:). While this has greatly increased performance and power efficiency, it has raised concerns that single-board computers, particularly those built around SoCs, are harder to repair and may be less friendly to attempts to monitor or modify instructions programmed into the boards by manufacturers. 812:
circuit boards are also not counted for determining if a computer is an SBC or not for two reasons, firstly because the HDD is regarded as a single block storage unit, and secondly because the SBC may not require a hard drive at all as most can be booted from their network connections.

The 2010s were defined by rapid and sustained growth in single-board computers, enabled largely by advances in integrated circuit production techniques that made it possible for the first time to include most or all of the core components of a motherboard on a
694:. Single-board computers are a market niche and are manufactured less often and at a higher cost. Motherboards and SBCs now offer similar levels of feature integration meaning that a motherboard failure in either standard will require equivalent replacement 761:. In the Intel PC world, the intelligence and interface/control circuitry is placed on a plug-in board that is then inserted into a passive (or active) backplane. The result is similar to having a system built with a 687:. Because of the very high levels of integration, reduced component counts and reduced connector counts, SBCs are often smaller, lighter, more power efficient and more reliable than comparable multi-board computers. 580:
increased demand for small, cheap components that would allow unconventional devices to access the Internet. Both of these factors dramatically increased production of single-board computers throughout the decade.

Some single-board computers have connectors that allow a stack of circuit boards, each containing expansion hardware, to be assembled without a traditional backplane. Examples of stacking SBC form factors include
