When most people think of computers, the image of a PC or laptop comes to mind. Some may even recall the football pitch sized computers of the 1960s and 70s before the emergence of the PC. Very few people would picture single board computers, even if there was one sitting right in front of them!
A single board computer is the terminology used for a printed circuit board that contains a processor, memory, I/O (input/output), and a clock. Single board computers (SBCs) resemble the motherboard contained in a typical PC, but include all the elements of a basic computer within its small design.
Since the early 1980s, the technology behind this type of computer has been used in industrial manufacturing and computerized product design to apply basic processing functions for high-tech product features.
The Uses Of Single Board Computers
Also commonly referred to as embedded computers, single board computers are used in products from aeroplanes and rocket ships to toys and high-performance athletic shoes.
Almost everyone uses single board computers without being aware of their existence. Most products that utilize computer technology (such as fax machines, cameras, cell phones etc.) contain embedded single board computers. It is for this reason that single layer PCB board manufacturers – and those who provide other components for SBCs – have seen a huge growth in their industry over recent decades.
While these tiny computers can host a full-size operating system such as Windows XP, most SBCs have internal operating systems that take up much less space. This is because simpler operating systems equal a lower cost per computer.
Software for single board computers is generally contained on a flash memory system or ROM chip. Quality indicators for single board systems include processor performance, I/O compatibility, SSD storage, and wireless capabilities.
The Pros And Cons Of Single Board Computers
There are advantages and disadvantages to using SBCs for industrial and product enhancement. Deciding whether or not to implement single board computer technology is largely a matter of necessity and cost.
Some of the deciding factors on using them include:
+ Pro: Current technologies have increased the capability of the single board computer while reducing its size and cost.
+ Pro: Wireless technology has made it possible for easy internet access via SBC.
+ Pro: The competitive market has greatly expanded the options and functionalities available for SBCs.
+ Pro: Advanced computer technology offers reliability for industrial manufacturers and quality products for vendors using SBCs.
– Con: Incorporation can be costly for high volume products and applications.
– Con: Some applications require customized sizes or I/O functions that are not compatible with standard SBCs.
Single Board Computer Technologies
While all SBCs are built using similar standards, different technologies can be included with individual SBCs. Video capability, Ethernet access functionality, and digital computer technologies are just some of the features that can be incorporated into a single board computer.
In general, SBCs can be as simple or as complex as an application demands. Additionally, supplemental hardware such as backplanes and mezzanine structures can significantly increase the functionality of a single board computer.
