Also referred to as System on Module (SoM), the CoM (Computer on Module) is a ready-to-use computer system. The com modules consist of application-agnostic software and hardware for developing embedded products. It is a physical module that includes a host of common computing elements. Some of the standard components are Bluetooth radio, flash memory, RAM, PCU, Ethernet bus, power management unit, and so on. The accessibility of such hardware elements as one centralized unit eliminates the complexity of the designs of end products.

What is a Computer on Module?

CoM (Computer on Module) is a tiny single-board computer encompassed in a host of embedded system designs. In other words, it can be considered as an entire CPU developed and designed into a single package. Once a user leverages a computer device on the custom-designed module, he/she can experience a custom-engineered solution along with the convenience of a ready-to-use single-board computer.

Why use a CoM?

CoMs have proved to be beneficial for developers, curtailing expenses, and reducing time-to-market. When an embedded system is developed, it is a time-consuming and lengthy procedure, including customized board designs and manufacturing. A System on Module can streamline the stages and execute the design optimally. It is necessary to choose a CoM or SoM that fits the needs, easily integrates into the end system, and is ready for deployment. They are used across the globe in several applications.

Security cameras

State-of-the-art security cameras take the advantage of video analytics and CoMs make it possible. Video analytics-backed security cameras make use of machine learning to classify and understand the functioning process and thereby providing accurate data in real-time. This wouldn’t have been possible if cameras had not been developed with computing functions and the potential for devices to assess information in real-time.

Machine vision

A present-day economy depends on machine vision for almost everything. Whether there is the detection of any errors, signature recognition, or inspection of the inventory, machine vision is necessary. It requires embedded systems that can assess data right on the spot and provide sensor potential that can be easily configured. The developers can seek advantage of machine vision in a way that the expense is at the lowest. This is possible because of the presence of com modules.

Smart cities

Smart cities equip a host of sensors everywhere possible to acquire the maximum data. The data collected provides an insight to the decision-makers so that they can keep the communities functioning 24*7. Systems on Modules or Computers on Modules have the responsibility to power the sensors and help the city officials and other decision-makers to execute everything starting from traffic to utilities without missing out a single second.


Whether one calls Computer on Modules, or System on Modules, it is a great addition to any embedded design and development of smart and IoT (Internet of Things) devices. The compact and powerful com modules have a reputation for offering a host of benefits like scalability, cost reduction, fast application development, durability, minimal risks, faster time-to-market, and so on.
