PC/104 Module-VEX-6254 (400MHz)


The NAD11-103-SD PC/104 family of low-power x86 embedded controller
is designed to meet PC/104 specification with backward compatibility to
provide migration path for projects facing end-of-life challenges with their
existing x86 based PC/104 controller.

In addition, the NAD11-103-SD family of controller is designed as a plug in
replacement, with backward compatibility to support legacy software to help
extend existing product life cycle without heavy re-engineering.

The NAD11-103-SD is suitable for broad range of data-acquisition,
industrial automation, process control, automotive controller, AVL, intelligent
vehicle management device, medical device, human machine interface,
robotics, machinery control and more.
