BayCat
PC/104-Plus Single Board Computer
Overview
Highlights
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 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 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 singlecore 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 its 10+ year
extended life programs, the BayCat provides a durable embedded
computer solution with an excellent cost of ownership.
