Introduction
5
Although configuration and application possibilities with PC/104 modules are practically
limitless, there are two ways to use them in embedded system designs:
h
Standalone Module Stacks
PC/104 modules are self-stacking. The modules are used like ultra-compact bus boards
but without a need for backplanes or card cages. Stacked modules are spaced 0.6
inches apart. (The three-module stack measures 3.6 by 3.8 by 2 inches.) Companies
using PC/104 module stacks within their products frequently create one or more of
their own application-specific PC/104 modules.
h
Component-line Applications
In this configuration, the modules function as highly integrated components, plugged
into custom carrier boards that contain application-specific interfaces and logic. The
modules' self-stacking bus can be useful to install multiple modules in one location.
This facilitates product upgrades or options and allows temporary addition of modules
during system debug or test.
