A single board computer (SBC), also known as a single-board microcontroller or a single-board microcomputer, is a complete computer system built on a single circuit board. It is a self-contained, compact computer that integrates all the essential components required for the functioning of a computer system, including the processor, memory, input/output interfaces, and storage. The design of an SBC allows it to function as a limited but fully operational computer.
Typically, an SBC consists of a central processing unit (CPU), random-access memory (RAM), non-volatile memory (such as flash memory), input/output (I/O) interfaces (e.g., USB ports, video output, Ethernet), and power supply components. These components are tightly integrated on a single board, reducing the size and complexity of the computer system.
Single board computers are widely used across various industries and applications. They are commonly employed in embedded systems, robotics, IoT (Internet of Things) devices, and educational settings. Due to their small form factor, SBCs are often utilized in applications where space is limited or portability is required.
Some popular examples of single board computers include the Raspberry Pi, Arduino, BeagleBone, and Intel NUC. These SBCs are known for their versatility, ease of use, and affordability, making them accessible to both professionals and hobbyists. They provide a platform for users to develop and deploy custom software and applications, making them a valuable tool for learning, prototyping, and small-scale computing needs.
