The VL-EPHs-P1 expansion module provides Mini PCIe socket expansion for any SUMIT-based embedded system. With a small footprint, simplified interface, and extensive ruggedization, the cost-effective VL-EPHs-P1 provides versatile PCI Express® Mini Card expansion for small form factor embedded systems.

As with all VersaLogic products, the VL-EPHs-P1 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-EPHs-P1 provides a durable embedded computer solution with an excellent cost of ownership. The VL-EPHs-P1 is fully RoHS compliant.


The VL-EPHs-P1 expansion module is a 90 mm x 32 mm (3.54” x 1.26”) SUMIT-micro format card that utilizes the PCIe and USB lanes of the SUMIT-A connector to provide a Mini PCIe socket for embedded system expansion. The card mounts to the top of the SUMIT stack and is secured via two mounting holes using standard hardware standoffs.

The versatile PCIe Mini Card socket accommodates plug-in Wi-Fi modems, GPS receivers, MIL-STD-1553, solid-state storage, and other plug-in devices. The VL-EPHs-P1 is compatible with full- sized Mini PCIe cards and supports both USB and PCIe connectivity. Half-sized Mini PCIe cards can be supported by special order. Four on-board LEDs provide Activity status for the Mini Card socket.

Designed for full industrial temperature (-40° to +85°C) operation, the rugged VL-EPHs-P1 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.
