Interchangeable COM Express modules

Diamond Systems has unveiled its COM-based Vega single board computer family. The single board computers come with interchangeable COM Express modules and CAN ports via an extension board.

HIGHLIGHTS OF THE FAMILY INCLUDE INTERCHANGEABLE COM EXPRESS COMs for scalability and long product life, high feature density in a compact size, integrated high-quality data acquisition, expandable I/O, conduction cooled thermal solution for improved reliability, and rugged construction.

Designed in the COM Express Basic form factor (125 mm x 95 mm), the family offers performance scalability with three COM Express processor options: a 2,1 GHz Intel Core i7-3612QE, a 1,7 GHz Intel Core i7-3517UE, or a 1,4 GHz Intel Celeron 827E CPU. The use of interchangeable COM Express modules helps extend product lifecycles or keep up with market needs by making it easy to replace an obsolete CPU or increase processing performance simply by replacing the COM module.

The product’s two-board COM and baseboard construction yields the highest feature density possible in a given footprint according to the manufacturer. The family utilizes an integrated baseboard with a range of I/Os, including a full data acquisition circuit that normally calls for a separate I/O board. Standard PC-type I/Os include VGA and a dual-channel LVDS display, four USB 2.0 ports, four EIA-232/422/485 ports, dual Gigabit Ethernet, SATA, and HD audio. The SBCs (single board computer) also feature a 7-V to 36-V power supply, making them compatible with most common vehicle and industrial power supply voltages.

The integrated data acquisition includes 16-bit A/D and D/A, digital I/O, and counter/timers, all supported by the company’s Universal Driver data acquisition programming library. An interactive graphical control panel for Windows and Linux is also provided to control all data acquisition features.

The SBCs support stackable I/O expansion with EMX (Embedded Xpress) I/O modules as well as a dual-use PCIe Mini Card / mSATA socket for additional I/O expansion. I/O modules featuring serial ports, Ethernet, analog I/Os, digital I/Os, CAN, and WiFi are available in the PCIe Mini Card form factor. For rugged applications, wide temperature mSATA disk modules in either SLC or MLC technologies are available with up to 64 GiB capacity.

Embedded Xpress is an industry standard form factor for embedded computers that offers stackable I/O expansion. It incorporates previous stackable I/O systems and extends them to better fit today’s technologies and customer needs. EMX supports many popular expansion buses while reserving sufficient pins for future definition.

The SBC’s built-in heat spreader efficiently removes heat directly to the system enclosure and helps keep the interior cooler for improved reliability. The bottom-side mounting configuration of the heat spreader provides a mounting system for the board. It also simplifies the installation of I/O expansion modules by eliminating interference or airflow problems that can occur with traditional heat sinks.

The SBC family was designed with rugged applications in mind. With an operating temperature of -40 °C to +85 °C, an integrated heat spreader thermal solution, thicker PCB, and latching I/O connectors, the SBCs are a fit for rugged applications including industrial, medical, on- vehicle and military. They are also available in off-the-shelf hardened and configurable systems.
