Intel Atom "Bay Trail" based SBC with PC/104-Plus Expansion

The BayCat from VersaLogic is a low-power / high-performance PC/104-Plus single board computer (SBC) based on the Intel Atom E38XX 'Bay Trail' processor. This set up makes it easy to upgrade existing systems to a powerful 4th generation Atom processor, while maintaining plug-in expansion for existing I/O boards.

With a full set of on-board I/O interfaces, including USB 3.0, mini PCIe expansion socket, TPM chip, and a 24 bit digital I/O port the Baycat is an ideal solution for size, weight and power (SWaP) sensitive applications.
