Embedded PC/104+ Module


The Panther is designed for projects requiring fast processing, compact size, flexible memory options, high reliability, and long product lifespan / availability. This is a complete computer system in a compact two board set. It may be used alone or with PC/104 or PC/104-Plus expansion modules.

The Panther is fully compatible with a wide selection of popular operating systems including Windows CE, QNX, Windows NT/95/98, Linux, RT-Linux, OS-9, and other Real Time Operating Systems.

Up to 256 MB of low power system RAM can be used in the high-reliability latching 144-pin SODIMM socket. Bootable DiskOnChip Flash is supported for non-volatile program and data file storage without the use of mechanical disk drives.

The high reliability design and construction of this board features latching I/O connectors, watchdog timer, voltage sensing reset circuit, spread spectrum frequency generation for lower EMI, industrial long-life battery, and self-resetting fuse on the 5V supply to the keyboard, mouse, and USB ports. An onboard programmable CPU temperature sensor permits use in difficult thermal situations. The sensor output can be used to turn on additional fans, create local or remote warnings, or take other action through software triggers.

The Panther delivers both full performance and product longevity by utilizing only standardized components in its design. Features such as full Socket 7 compatibility were made possible by its unique 2-board design with PC/104-Plus interconnect. The Panther is designed to mount at the top of a PC/104 stack due to fan / heat sink height. Other configurations are possible depending on the environmental characteristics of the application.

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 design team. Both hardware and software (BIOS) customization are available in 100 unit quantities. Each board is subjected to burn-in and complete functional testing and backed by a limited two-year warranty.

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.

VersaLogic delivers extremely reliable standard and customized embedded computers backed with unsurpassed service and the highest availability in the market. VersaLogic exists to exceed customers' product, service, support and delivery needs - whenever and wherever the need arises.
