COM Express was developed and is maintained by PICMG (PCI Industrial Computer Manufacturers Group). COM Express was released in the summer of 2005 and is the most widely used COM standard. The standard defines the physical size, interconnect, and thermal interface for a COM.The original COM Express specification was written to support peripherals that were available at the time of release – including USB 2.0, SATA, PATA, Ethernet, VGA, LVDS, SDVO, PCI, and PCI Express Gen 1. Several pinout types were defined by PICMG with each one having a specific combination of peripherals, expansion interfaces and connector layout. The most widely used COM Express module is a type 2, followed by type 1.
With the introduction of new display interfaces in the embedded market such as HDMI and Displayport it was time for a major upgrade of the COM Express specification. In the summer of 2010. The updated specification was called “PICMG® COM.0 rev 2.0”. and defined a new type 6 that allowed for HDMI, DVI and Displayport display interfaces, for USB 3.0 and for more PCI Express lanes. Besides the pinout changes two more form factors where formalized : COMPACT (95x95mm) and Mini (84x55mm).
The ADLINK computer-on-modules with built-in SEMA Cloud functionality is ready-made for Internet of Things (IoT) applications. ADLINK COM Express modules are able to connect legacy industrial devices and other IoT systems to the cloud, extract raw data from these devices, determine which data to save locally and which to send to the cloud for further analysis. The results these analyses can provide valuable information for policy decision making and generate innovative business opportunities.
A computer-on-module (COM) is a complete computer built on a single circuit board. However, unlike a single-board computer, the COM lacks the standard interfaces for input/output and connection to peripherals. These signals are brought out through standardized connectors to a custom carrier board which is designed for the specific embedded application.
