MEN Mikro's G51 single-board computer unites the benefits of CompactPCI® Serial and the interface capabilities and calculation power of a QorIQ™ CPU. Being based on a Freescale™ quad-core QorIQ™ P3041 processor, the 3U, 4 HP SBC provides a large number of high-speed serial interfaces both at the front and at the CPCI-S.0 rear connectors.

Three Gigabit Ethernet channels at the front and a standard five ports at the rear provide solid connectivity. The three front ports can also be routed to the rear so that the maximum of eight Ethernet channels defined by CPCI-S.0 are available on the backplane. This routing option is a standard feature, and can be set in the U-Boot boot loader.

In a similar way, the G51 single-board computer comes with two SATA 2.x channels, where one can either be used for an onboard mSATA disk, or as a second port at the rear - also switchable via U-Boot. SGPIO is available, too.

The G51 comes with six standard rear USB 2.0 ports, and the two standard front interfaces can be led to the rear as a hardware option, for a total of eight backplane channels. Four PCI Express® links (two x1, one x2 and one x4) add another important column of CompactPCI® Serial features to the G51's rear I/O.

Its abundant connectivity, flexible configuration options and multi-core computing performance make the G51 a universal off-the-shelf platform for all kinds of communication and processing tasks. Data acquisition, data encryption, simulation and process control systems are only a few examples. Suitable CompactPCI® Serial peripheral cards are available to add specialised functions in a modular system where necessary.

Apart from its connectivity, the card comes with fast DDR3 RAM, a microSD™ card slot, a number of board management functions and Linux BSP support. All components are soldered for protection against shock and vibration and withstand an extended operating temperature of -40°C to +85°C. As an option, the board can be equipped with M12 Ethernet front connectors. The G51 is also ready for coating so that it can be used in humid and dusty environments.

All this makes the G51 a perfect choice for railway, avionics or marine applications, but also for fields like automation or power & energy, where computers face harsh environments.
