Description

The Bobcat single board computer is designed for projects requiring low cost, compact size, high reliability, and long product lifespan/availability. It can be used alone as an Ethernet node processor card, or with a plug-in video module in applications requiring a video display.

The Bobcat is a complete computer system on a single PC/104 sized board. It may be used alone or with a wide variety of PC/104 and PC/104-Plus expansion modules.

The board includes 64 MB of low power system SDRAM which is soldered in place to increase reliability in hostile environments. It also supports bootable DiskOnChip Flash chips to allow program and data file storage without mechanical disk drives.

The high reliability features of the Bobcat include watchdog timer, voltage sensing reset circuit, industrial long-life battery, and self-resetting fuse on the 5V supply to the keyboard and mouse.

This exceptional processor card was designed from the ground up for OEM applications with longevity and reliability as the focus. It is fully supported by the VersaLogic application team. Both hardware and software (BIOS) customization are available in 100 unit quantities. Each board is subjected to burn-in and complete functional testing.

The Bobcat is compatible with a wide selection of popular operating systems including most Windows and Real Time OSs. Please contact VersaLogic for more information.
