Embedded PC/104+ ModuleRoHS-compliant



The VL-EPM-V4 expansion module provides video capabilities for PC/104-Plus embedded systems. With a full industrial temperature rating and rugged construction, the VL-EPM-V4 is an ideal solution for embedded video applications in harsh, mobile, and/or remote environments.

The VL-EPM-V4 is designed to support OEM applications where high reliability and long-term availability are required. From application design-in support, to the 5+ year production life guarantee, the VL-EPM-V4 provides a rugged embedded computer solution with an excellent cost of ownership. The VL-EPM-V4 is manufactured and tested to the highest quality standards and is fully RoHS compliant. Customization is available, even in low OEM quantities.


Based on the PC/104-Plus standard, the VL-EPM-V4 supports PCI and ISA stackable expansion buses on an industry-standard 90 mm x 96 mm (3.55” x 3.78”) expansion module.

Utilizing an SiS™ Volari™ Z9M GPU for high-performance graphics capabilities, the VL-EPM-V4 provides analog VGA and LVDS video output (simultaneous).

The on-board video BIOS supports VESA™ standard graphics modes. The VL-EPM-V4 can be used as a development tool for VersaLogic's headless (no video output) Tomcat and Newt single board computers or to provide a secondary video output for any PC/104-Plus embedded system.

The Z9M GPU features advanced power reduction (throttling) and power down (sleep) controls, which can be accessed in various ways depending on the operating system in use.

Designed for full industrial temperature operation (-40° to +85°C), the VL-EPM-V4 is built to withstand thermal extremes. The VL-EPM-V4 board also meets MIL-STD-202G specifications for mechanical shock and vibration for use in harsh environments.

The VL-EPM-V4 is compatible with a variety of popular operating systems including Windows, Windows Embedded, Linux, VxWorks, and QNX using standard software drivers.

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.
