Single-board Computers

Introduction

A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. Single-board computers were made as demonstration or development systems, for educational systems, or for use as embedded computer controllers. Many types of home computer or portable computer integrated all their functions onto a single printed circuit board.

Unlike a desktop personal computer, single board computers often did not rely on expansion slots for peripheral functions or expansion. Some single-board computers are made to plug into a backplane for system expansion. Single board computers have been built using a wide range of microprocessors. Simple designs, such as built by computer hobbyists, often use static RAM and low-cost eight or 16 bit processors. Other types, such as blade servers, include all the memory and processor performance of a server computer in a compact space-saving format.
