An Overview Of Computer on Module (CoM)

When building embedded systems, the CPU infrastructure configuration takes too much design time. As semiconductor technology advances and becomes more technologically sophisticated, designing FPGAs and microprocessors become complex and time-consuming. Using the com module in embedded units eliminates the need for additional production time to create complicated and diverse CPU subsystems. An off-the-shelf CoM can increase the company’s profit margin by employing scale savings and cutting project costs. CoM technology also helps manufacturers increase production speed without increasing costs or sacrificing quality.

What is Computer on Module?

The Computer on Module (CoM), often called System on Module (SoM), is a ready-to-use computing system with a form factor that includes hardware and software that is application-neutral for developing embedded solutions. This is a physical module that combines a variety of standard computing components. RAM, a CPU, a power management unit, flash memory, Bluetooth radio, WiFi, and an Ethernet bus are all included as standard features. The presence of these embedded parts as a single unit simplifies end-product design.

How Does Computer on Module Work?

The edge connector fixes the interfaces. The module is also connected to the hauler board, which links the interface to the connectors or application-specific parts located on the carrier board. The modules can also be found on off-the-shelf carrier boards, which can be utilized to build a variety of applications. Com Module significantly reduces the complexity and risks associated with developing and handling products while keeping higher form factor flexibility.

Importance of Computer on Module Work

COMs are known for their versatility. A com module provides end users with a variety of application capabilities, faster product development, and the ability to customize it to fit specific performance and functional needs while staying within the overall power budget. These units include pre-installed operating systems and integrated support for significant frameworks, development platforms, and third-party software.

Generally, this is an entire CPU designed into a compact package. Using a computer in the design offers the benefits of a custom-engineered solution with the convenience of a ready-to-use single board. The complexity is significantly reduced by using COM, and end users get several competitive benefits.

  • COMs provide superior performance, and with fewer providers, the danger of failure is reduced.
  • Baseboard size, functionality, and connector placement can all be tailored to the product and end-use application.
  • Engineering expenditures and other costs associated with producing a chip-down CUP can be drastically decreased or even eliminated.


Using the design concepts of a com module can save development costs and timelines, allowing for the quicker introduction of new products to the market. The sooner a product can be developed and commercialized, the faster and more effectively it can be used. The integration of mezzanine modules (modules that ‘plug into’ the base/carrier board) facilitates upgrading to newer, backward-compatible versions. COM is a popular and widely used version of module design that is widely used in Industrial, Military/Aerospace, Gaming, Medical, Transportation, IoT, and basic integrated computing applications.
