A Single Board Computer (SBC) is a complete computer that is built on a single circuit board with memory, input and output devices, processors, and other peripheral functions of the computer. SBC can be used for developmental purposes, educational institutes, as well as industrial, automation, and military applications. Home computers and portable computers are also integrated into a single printed circuit board. SBCs do not rely on the expansion of slots for peripheral functions. Simple SBCs use static random-access memory (RAM) and low-cost 8 or 16 bit processors.
