The VL-EPHs-B1 expansion module provides plug-in access to the additional USB capabilities provided by SUMIT-enabled embedded computers. With a small footprint, simplified interface, and extensive ruggedization, the VL-EPHs-B1 is an ideal solution for all embedded applications that require additional USB capabilities.

The VL-EPHs-B1 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-EPHs-B1 provides a rugged embedded computer solution with an excellent cost of ownership. The VL-EPHs-B1 is manufactured and tested to the highest quality standards and is fully RoHS compliant. Customization is available, even in low OEM quantities.


The VL-EPHs-B1 provides USB signals from the SUMIT-A connector on a 90 mm x 32 mm (3.54” x 1.26”) mezzanine “SUMIT-micro” card. It mounts to the top of the SUMIT stack using two hardware standoffs. The VL-EPHs-B1A provides two Type A USB ports while the VL-EPHs-B1B provides one Type A USB port and an eUSB interface for flash storage. Both models also provide two additional USB channels via a 10-pin header. A transition cable is available which provides two USB Type A ports from the 10-pin header.

Designed for full industrial (-40° to +85°C) temperature operation; the VL-EPHs-B1 meets MIL-STD-202G specifications for mechanical shock and vibration for use in harsh environments. Transient voltage suppression (TVS) devices on all USB channels provide enhanced electrostatic discharge (ESD) protection for the system.

The VL-EPHs-B1 is compatible with a variety of popular operating systems including Windows, Windows Embedded, Linux, VxWorks, and QNX.
