Embedded computer modules are highly integrated single board computers particularly suited for

implementing customized solutions. Embedded computer modules are used when standard single board

computers are not suitable for mechanical reasons or due to a lack of expandability.

The difference between boards and

modules

Embedded computer modules are very small

computer boards that can be integrated in

almost every application without a cable

connection. Every signal is transmitted via small,

densely packed board-to-board industrial con-

nectors to a customer- or application-speciﬁc

carrier board. This carrier board contains all the

hardware expansions and also allows the cable

less distribution of the required interfaces.

Computer boards are equipped with numerous

and various connectors in order to allow the

connection of a variety of peripherals and

expansions. Complex solutions based on com-

puter boards require many cable connections,

which is frequently a cause of problems during

tough industrial use.

Customer speciﬁc solution

The carrier board contains all the special

functionalities required by the corresponding

embedded application. This could be special

interfaces, a unique power supply, as well as the

mechanical design and the slot placement. The

embedded computer module itself is plugged in

like a component. This ”component” represents a

complete computer that is the intelligence of the

application.

Cooling

The heatspreader serves as a thermal interface

between the embedded computer module and

the cooling solution of the system.

Thus, e.g. the excess heat can be

passed directly to the system

housing. The heatspreader is

deﬁned in the COM speciﬁcation

and is uniformly implemented

for all modules.

Flexible and robust

mechanical solutions

In comparison to most computer

boards, modules are very small

and allow for very compact solutions.

Because the modules are ﬁrmly screwed

down, solutions are possible even for the

most difﬁcult environmental conditions.

Economical

By avoiding expensive and sensitive cable

connections, solutions based on embedded

computer modules are already economical in

mid-sized quantities.

Scalability

congatec currently offers modules from 500 MHz

to 2.53 GHz. However, not only is the computer

performance scalable, but also the interface

conﬁguration. You get precisely the performance

your application needs.

Long-term availability

The excellent long-term availability of all

congatec modules is further extended as a result

of the clearly deﬁned module interface enabling

broad market offers.

Computer-On-Modules - the concept

Minimized development risk

The complexity of carrier board development is

signiﬁcantly reduced when embedded computer

modules are used. With lower complexity, the

probability of error is naturally lower as well. This

means the cost and time frame of the project

can be met with a signiﬁcantly lower risk.

Time-to-market

With a module-based solution, a complex CPU-

board design with accompanying BIOS develop-

ment is not necessary. Modular solutions are

therefore ready for market signiﬁcantly faster.

To accelerate the time-to-market even further,

congatec offers starter kits. With this, hardware

and software development can get under way

immediately. Appropriate board-support pack-

ages for all standard operating systems provide

an additional head start.
