2.1GHz Quad Core CPU, Up To 16GB DDR3 Memory, SATA RAID

Manufacturer: duagon MEN

The CB71C is an ultra-rugged COM Express module for rail, public transportation and industrial applications, e.g. data acquisition, infotainment, transcoding, live 3D. It is 100% compatible with COM Express Type 6 Pin-Out and conforms to the VITA 59 standard which specifies the mechanics to ensure reliable operation even under the harshest environmental conditions.

Perfect for Harsh Environments

The modules are embedded in a closed aluminium frame, which ensures optimum EMC protection and efficient conduction cooling. Direct air cooling is possible by placing a heat sink on the cover. The CB71C is designed for operation from -40°C to +85°C (housing). To withstand serious shock and vibration, only soldered components are used. The design is optimized for conformal coating.

Powerful Processing and Graphics on a Single Chip

The CB71C is based on AMD's V1000 APU family. It is equipped with a Radeon Vega next-generation 3D graphics engine and supports up to 4 displays with a resolution of up to 4k without the need for additional graphics hardware. With up to four high-performance processor cores and AMD-V extension, the CB71C is also suitable for virtualization.

Excellent Price/Performance Ratio, Flexible Design

The CB71C can be equipped with a wide range of long-term available processors with scalable performance, all supporting ECC. Passive cooling is possible with low-power versions.

Safety and Security

The board features an advanced board management controller with monitoring functions for safety-relevant applications. In addition, the CB71C has a Trusted Platform Module and supports hardware memory encryption, providing protection against both physical and inter-VM storage attacks. This is essential for security-critical applications such as payment and ticketing terminals, fleet management or monitoring. 

Memory and I/O

The CB71C can be equipped with up to 32 GB of directly soldered DDR4 main memory and a 16 GB eMMC. Available high-speed interfaces include PCI Express 3.0 links, DDI (DP, eDP, HDMI), SATA 3.0, Gigabit Ethernet and USB 3.0.
