Embedded Computer-on-Modules - Congatec

What are CoMs?

Computer-on-Modules (CoMs) are small circuit boards that are plugged into standardized connectors on an application-specific carrier board. As application-ready super-components, these modules include all key embedded computing building blocks such as CPU, GPU, and RAM as well as a broad set of standard interfaces in a function-validated complete package.

Within one CoM standard, all interfaces are routed via the same dedicated signal pins to the standard-compliant carrier board, which makes modules interchangeable across different vendors and processor generations.

The application-specific circuit parts are accommodated on the carrier board.  When designing your carrier board, you decide which of the electrically available computer properties you actually need, and which extensions you want to develop.

This CoM approach enables engineers to cost effectively design innovative solutions within the shortest time to market and to stay highly agile to adapt to technical evolutions.

A Computer on Module (CoM), also known as a System on Module (SoM), is a single physical module that incorporates many common computing components. Common CoM components include a CPU, RAM, flash memory, a power management unit, an Ethernet bus and Wi-Fi and Bluetooth radios. The availability of all this hardware as a single unit reduces the complexity of final product designs.

Toradex SoMs also come with ready-to-use operating systems and integrated support for popular development environments, frameworks and other third-party software. All the Interfaces are available on an edge connector. The module is plugged into a carrier board that attaches the interfaces to connectors or application-specific components hosted on the carrier board. A carrier board is often simple to build, as all the complexity is contained within the module. This makes it possible to develop four-layer carrier boards with prices below US$20, for example.

Toradex and our partners also provide off-the-shelf carrier boards which can be used for development in a wide range of applications. System on Modules greatly reduce the complexity and risk of developing and maintaining a product while maintaining high flexibility in the form factor.
