COM Express® Functionality
All Kontron COM Express® basic and compact modules contain two 220-pin connectors; each of which has two rows
called row A & B on the primary connector and row C & D on the secondary connector. The COM Express® Computer-
On-Module (COM) features the following maximum amount of interfaces according to the PCI Industrial Computer
Manufacturers Group (PICMG) module pinout type.

COM Express® Benefits
COM Express® modules are very compact, highly integrated computers. All Kontron COM Express® modules feature a
standardized form factor and a standardized connector layout that carry a specified set of signals. Each COM is based
on the COM Express® specification. This standardization allows designers to create a single-system baseboard that
can accept present and future COM Express® modules.
The baseboard designer can optimize exactly how each of these functions implements physically. Designers can
place connectors precisely where needed for the application, on a baseboard optimally designed to fit a system’s
packaging.
A single baseboard design can use a range of COM Express® modules with different sizes and pinouts. This flexibility
differentiates products at various price and performance points and provides a built-in upgrade path when designing
future-proof systems. The modularity of a COM Express® solution also ensures against obsolescence when computer
technology evolves. A properly designed COM Express® baseboard can work with several successive generations of
COM Express® modules.
A COM Express® baseboard design has many advantages of a customized computer-board design and, additionally,
delivers better obsolescence protection, heavily reduced engineering effort, and faster time to market.
