What is a computer with a single board?
One -board computer (SBC) is a type of computer with all its components built into a single circuit board. SBC size may vary from credit card size to video game console size. They are often integrated into larger devices such as automatic cashier machines, industrial and medical equipment or robotic equipment. Since the mid -2000, cheap computers with individual boards have been used by teachers and fans.
Desktop and even notebooks (PC) personal computers (PCs) have generally separate components connected to the central circuit board via cables or bus. One board computer packs all its necessary components, including a microprocessor, memory and storage, on a single circuit board. Many SBCs are created to be compatible with PC and use the same processors, memory and graphics chips as standard computers. Other units include different types of hardware and some have a microcontroller, a specialized processor with built -in input/output FUNKceionty. Some SBCs are expandable or partially reconfigurable, while others are glued to what they supplied with.
The size of the computer with one board can vary very much, but most of them are much smaller than a typical PC. First, such devices that were introduced at the end of the 70s and the early 80s were usually found in educational or development computers and was quite large. Since then, the trend towards smaller SBC, from a slightly smaller than the size of the credit card to the size of the Blu-ray® player. They can come in both standard and non -standard sizes, and several of them are even based on the same size as the normal expansion card or PC memory card.
One board computers are normally located inside a larger device or product, giving additional intelligence or controlling the functions of machine or device. Automatic cashier machines, cash registers, DOtykové screens and many other machines and devices often contain an embedded computer with one board. They are also used in industrial computers and automation facilities, robotics, medical devices and many other fields. Due to the number of uses, SBC comes in various configurations and many manufacturers build machines adapted to a specific need or industrial application.
In the middle of 2000 years, computer components' costs have dropped sufficiently to get a one -board computer to reach community hobbyst. Several companies now specialize in cheap but versatile SBCs for use in amateur electronics and computing projects. These devices can be used themselves to introduce students with computer programming or as part of a larger platform such as a robot or an interactive art display.
