2.1 Product Description
COM Express modules are compact, highly integrated Single Board Computers.
Typically a COM Express module consists of CPU, chipset, memory, video controller,
Ethernet controller, BIOS flash and EIDE-, SATA- and USB controller. Interface
controllers (e.g. for PCMCIA) or connectors (e.g. RJ45) are implemented on the base
board on to which the COM Express module can be mounted via one or two 220-pin
SMD-connectors. Beside the power supply also signals for PCIe- and PCI-bus, EIDE,
SATA, USB, LPC etc. are present on these connectors.
The type of interfaces that is led from the COM Express module to the base board
depends on the type of module that is used. The COM Express specification defines five
different types which differ in number and pin assignment of the module connectors.
Thanks to the standardized mechanics and interfaces the system can be scaled
arbitrarily. In spite of a modular concept the systems design is very flat and compact.
COM Express modules require a base-board for successful operation.
The base board described below acts as an evaluation board for the COM Express
modules.
