The Viper is a low power / high-performance single board computer (SBC) which combines Intel's advanced Bay Trail processor, with a traditional PC/104-Plus™ expansion interface. This combination makes it easy to upgrade existing systems to a powerful 4th generation Atom processor, while preserving plug-in expansion to existing specialty I/O boards. In addition, it also contains a full complement of on-board I/O interfaces, including USB 3.0, mini PCIe expansion sockets, TPM chip, A/D, D/A, and 32-bits of digital I/O.

Driven by a low power E3800 (Bay Trail) processor, with clock rates up to 1.9 GHz, the Viper features quad-, dual-, and single-core processor options.

Viper is built on the industry-standard EBX form factor. It includes legacy ISA and PCI connectors to interface directly with PC/104-Plus expansion boards.

As with all VersaLogic products, the Viper is designed to support OEM applications where high reliability and long-term availability are required. Viper is backed by a 5-year warranty, 5-year minimum off-the-shelf availability guarantee, and expert US-based technical support. From application design-in support, to its 10+ year extended life programs, the Viper provides a durable embedded computer solution with an excellent cost of ownership.

VersaLogic products are designed for use by OEMs working in a variety of market applications: Aerospace, Defense, Energy, Industrial, Security, Medical, Military, Robotics, and Transportation. Anywhere that the need for superb quality and high-performance embedded computing exists, applications include: automation, avionics, gateway, in-vehicle, monitoring, simulation, and vision.
