Overview
The VL-MPEe-U2 is an extremely small and rugged I/O module based on the industry-standard Mini PCIe
module format. Unlike typical I/O expansion boards, Mini PCIe allows additional I/O functions to be added
to a system with almost no increase in overall system / package size. Mini PCIe modules provide a simple,
economical, and standardized way to add I/O functions to embedded computer products.
Serial I/O
Four serial ports that support RS-232, RS-422, and RS-485 interfaces.
Digital I/O
Twelve general purpose I/O lines.
Details
In a very small package, this board provides four serial ports, twelve general purpose I/O lines, and three
indicator LEDs.
This serial plus GPIO module provides a traditional serial I/O interface for legacy communication. The serial
ports operate in 4-wire mode with auto-direction control and baud rates up to 400 Kbps. Each port can be
independently configured (hard jumpered) for RS-232, RS-422, or RS-485 operation.
The twelve GPIO lines are independently configurable as an input or output. GPIO inputs can be set for
normal or inverted level, and optionally set to generate an interrupt. GPIO outputs can be set to be normal
HIGH or LOW state, or open drain.
The on-board indicator LEDs include one power indicator and two user LEDs that can be jumpered to GPIO pins.
This rugged product is designed and tested for full industrial temperature operation (-40º to +85ºC). It
also meets MIL-STD-202G specifications for shock and vibration. Latching connectors provide additional
ruggedization, making it at home in harsh environments.
The VL-MPEe-U2 board includes device drivers and the VersaAPI Application Programing Interface. The
VersaAPI includes pre-defined calls to send or retrieve data from the on-board I/O ports. These calls
greatly simplify development of the user code needed to access these ports. On the VL-MPEe-U2 board,
the VersaAPI supports the on-board GPIO lines. The VersaAPI is compatible with Windows, Windows
Embedded, and Linux operating systems.
This I/O board is compatible with a variety of popular x86 operating systems including Windows, Windows
Embedded, Linux, VxWorks, and QNX.
The module utilizes PCIe signaling and can be used in any system that supports PCIe signaling at the
Mini PCIe socket.
It is manufactured to IPC-A-610 Class 2 standards. Class 3 versions are available for extremely-high-
reliability applications.
Product customization is available, even in low quantities. Options include conformal coating, application-
specific testing, BOM revision locks, special labeling, etc.
