What Is a Single Board Computer?
"Single Board Computer" or "Single Board Computer" (SBC), which assembles all parts of the computer on a printed circuit board, including microprocessor / memory / input / output interfaces, and simple Seven-segment LED display, keypad, socket and other external devices. The function is stronger than the one-chip computer, suitable for controlling the production process. Can be operated directly on the experimental board, suitable for teaching.

- In the early 1980s, the emergence of integrated circuit (IC) technology greatly reduced the size of computers and made them develop toward miniaturization. Functions that previously occupied the entire circuit board could be integrated into a single "large-scale integration" (LSI ) In the logic chip. CPU, memory, memory, and serial / parallel port LSI chips can now actually execute the entire microcomputer system on a single board-no backplane. The Z80-based "Big Board" (1980) may be the first such single board computer (SBC) to run a commercial disk operating system (CP / M).

- Similar to the big board, the "Small Board" (Ampro in 1983) uses the Z80 CPU and the target is the CP / M operating system. But its size is much smaller, matching the script printing of a floppy drive (5.75 x 8.0). Due to its unique close integration, simplicity, reliability, and low cost, the small board is suitable for commercial disk operating systems that are simply embedded directly into devices other than their computer.
- As a result, the embedded single board computer market has emerged. It is now crowded with hundreds of thousands of single board computer manufacturers, producing thousands of different single board computer products for different embedded and specialized computing applications.
- Initially, each single board product was completely unique-both structurally and morphologically. This is largely due to the inherent differences in embedded system requirements, combining various processors and available peripheral controllers. In addition, there are no standards that affect the function choices and mechanical specifications of single-board computer developers. [1]
