The XTEND, XA Trainer and Expandable Narrative Design, is designed to provide the user with a stable hardware and software platform for application development with the XA-H4.  In many cases the XTEND may serve as a quick prototype for the actual user application.  With the on-board prototype area or optional communications modules, the user can quickly and easily get a new customized design running with the XA-H4.  Since the XA-H3 is a subset of the XA-H4, the XTEND-H4 provides full support for either device.
