XC15 - Rugged COM Express Carrier Board

Rugged COM Express, based on PICMG standard COM.0 or COM Express, has been developed for demanding embedded applications with extended requirements for thermal design, shock, vibration and EMC. Rugged COM Express, together with an application-specific carrier board, forms a semi-custom solution which is suited for application in extremely harsh, mobile and mission-critical environments.

The XC15 is an evaluation and development platform that can be used together with any type of Rugged COM Express module. The XC15 provides physical interfaces and connectors for nearly all current serial standard I/Os, which can be routed from the COM Express connectors to the carrier board. The XC15 comes with one COM Express slot and eight PCI Express card slots, including an onboard PCI Express Graphics (PEG) interface on a standard PCIe x16 connector. In addition, it provides three display ports, four onboard SATA connectors, two LVDS and two CAN interfaces which are available via SA-Adapters.

The functionality of all connectors depends on the Rugged COM Express module used on the XC15. It supports the Micro ATX form factor and can therefore operate in a PC system. Additional USB ports on the front panel for USB driven Flash disks for application storage, complement the memory configuration that is already available on the different COM Express modules.

For a first evaluation of the functions and performance of the Rugged COM Express module of choice, we strongly recommend using the XC15. Further useful accessories include an external PSU, a heat sink and fan, a DisplayPort to DVI adapter, and cables for UART and SATA HD.
