Description

The BayCat is a low-power / high-performance single board computer (SBC) with a traditional PC/104-Plus expansion interface. This combination makes it easy to upgrade existing systems to a powerful 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 socket, TPM chip, and a 24 bit digital I/O port.

Driven by the low power E3800 (Bay Trail) processor, with clock rates up to 1.9 GHz, the BayCat features quad, dual, and single-core processor options. Based on the industry-standard PC/104 format (4.2 x 3.8 inches), this SBC is an excellent solution for size, weight and power (SWaP) sensitive applications.

BayCat is built on the PC/104 form factor. It includes legacy ISA and PCI connectors to interface directly with PC/104-Plus plug-in boards.

As with all VersaLogic products, the BayCat is designed to support OEM applications where high reliability and long-term availability are required. From application design-in support, to 10+ year availability, the BayCat 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. VersaLogic delivers extremely reliable standard and customized embedded computers backed with unsurpassed service and the highest availability in the market.
