Single-board computer
History and Evolution: The first true single-board computer, based on the Intel C8080A, emerged in the mid-1970s with schematics published in Radio-Electronics magazine. Early models like the MMD-1 by E&L Instruments were pivotal for prototyping electronic products and played a significant role in the development of home computers. While single-board computers faced challenges with the rise of PC extensibility, the 2010s witnessed a resurgence in popularity, notably with the introduction of the Raspberry Pi and advancements in integrated circuit production driven by the Internet of Things and smartphone growth.
Applications and Uses: Single-board computers find applications in various industries, offering compact and cost-effective solutions for gaming, kiosks, automation, industrial process control, deep-sea exploration, and space missions on rockets like Ariane and Pegasus. Their integrated design eliminates reliability issues associated with connectors, making them ideal for embedded applications. Embedded SBCs provide necessary I/O features without the need for plug-in cards and can be easily integrated into backplanes for expanded connectivity.
Components and Architecture: Single-board computers typically incorporate microprocessors, memory, and I/O features, serving purposes ranging from educational demonstrations to embedded controllers. They come in various forms, including computer-on-modules for system expansion and stack-type SBCs like PC/104 for memory expansion. SBCs are built around different processing structures such as Intel architecture, RISC, and SPARC, utilizing standardized form factors like CompactPCI, VMEbus, and PICMG for compatibility and versatility.
