The VL-EPMx-P2 expansion module provides dual Mini PCIe socket expansion for any PC/104-Plus or PCI-104 embedded system. With a small footprint and industrial temperature operation, the VL-EPMx-P2 provides versatile PCI Express Mini Card expansion for small form factor embedded systems.

As with all VersaLogic products, the VL-EPMx-P2 is designed to support OEM applications where high reliability and long-term availability are required. From application design-in support, to its 5+ year production life guarantee, the VL-EPMx-P2 provides a durable embedded computer solution with an excellent cost of ownership. The VL-EPMx-P2 is fully RoHS compliant.


Based on PC/104 standards, the VL-EPM-P2 supports PCI and ISA stackable expansion buses on an industry-standard 90 mm x 96 mm (3.55" x 3.78") expansion module. The VL-EPMp-P2 supports PCI stackable expansion. Using a PCI to PCI Express bridge, the VL-EPMx-P2 provides off-the-shelf PC/104-Plus and PCI-104 systems with full access to high-speed Mini PCIe devices.

The two on-board Mini PCIe sockets accommodate plug-in modules such as A/D convertors, Ethernet, Wi-Fi modems, MIL-STD-1553, solid-state storage, and other devices. The VL-EPMx-P2 is compatible with full-sized Mini PCIe cards. Half-sized Mini PCIe cards can be supported by special order. Four on-board LEDs provide Activity status for each Mini PCIe socket.

Designed for full industrial temperature (-40 to +85C) operation, the rugged VL-EPMx-P2 meets MIL-STD-202G specifications for mechanical shock and vibration for use in harsh environments.

Product customization is available, even in low OEM quantities. Customization options include conformal coating, revision locks, custom labeling, customized testing and screening, etc.

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.
