A Computer-On-Module: Everything You Need to Know

A Computer-On-Module is actually complete computer made on a circuit board and has memory, microprocessor, input/output as well as other features needed for a computer to function. Things like Single board computers were specifically made as development or demonstration systems or to be used as the embedded computer controllers. Most portable or home computers incorporate major functions onto one printed circuit board.

A Computer-On-Module does not depend on expansion slots for expansion. They are usually built using a huge range of microprocessors. Simple designs use static RAM as well as low-cost 16-or 8-bit processors. They are good teaching and experimentation tools because of their simplicity, and low cost. They are commonly used to control simple processes and tend to be slow. Examples of these computers include Arduino, Intel Thin, Raspberry Pi, and APC 8750.

When Can a Computer-On-Module Be Used?

These types of computers are commonly used in embedded applications. Embedded computers can’t be enlarged or expanded upon and have only the output as well as input capabilities. They can only do tasks they are specifically designed for. For instance, a vending machine can have a Computer-On-Module embedded in it to control all the functions and activities of the vending machine. Such systems have no provisions to add hardware with the intention of expanding its capabilities.

Why These Computers Are Applied in the Industry

A Computer-On-Module has the capability of performing most automated activities. Specialized designs are available in almost every part of the country. They have several benefits over using the usual computers for tasks to which single board laptops are normally put. They can be fixed in devices with limited space because they are generally small.

These computers are generally efficient and can be appropriate in situations where saving on power is important. Another good thing about them is that they are self-contained. They are generally reliable under different and trying environmental conditions. Although most single board laptops have a capacity less than those of multi-board computers, they are generally more expensive when compared to multi-board computers.

A Computer-On-Module is somehow a specialized facility, meaning that it’s not made in the same manner as the usual multi-board motherboards. These facilities are generally reliable and self-contained, making them cost-effective solutions for the industries. Nowadays, there are different types of these computers. The most common ones are those that make use of backplane connections. They appear in designs that perform excellently in architectures like Intel architectures. With backplanes, these computers can work well with connections like PCI and PCI-X.


A Computer-On-Module can be bought to perform a huge range of tasks. In fact, some have I/O interfaces with networking applications, wireless applications, audio applications, and many more. Being capable of buying these facilities already made to perform these tasks makes them extremely convenient. Although most of these computers have their components fixed on a single board, a good number of them have expansion slots that include common designs like Mini PCI, PCI Express, MicroSD, ISA, PCI, and many more. They can also be bought depending on the type of ports they have: VGA, CRT, HDMI, DVI, and others.
