Chapter 2 Product Overview
This introduction presents general information about Stackable architecture and the MiniModule SIO
expansion board. After reading this chapter you should understand:
• Stackable Architecture
• MiniModule SIO Features
• MiniModule SIO Product Description
• MiniModule SIO Major Components and Headers
• MiniModule SIO Specifications
Stackable Architecture
Stackable architecture affords a great deal of flexibility in system expansion. The SUMIT interface allows
you to add legacy I/O to a legacy-free CoreModule board by simply stacking an ADLINK MiniModule SIO
board onto the CoreModule SUMIT connectors. Expanding a simple CoreModule system by adding self-
stacking MiniModule SIOs or 3rd party PC/104 expansion boards provides functional capabilities such as:
• Analog or digital I/O (including serial, parallel, and USB 2.0)
• PCIe links
• ISA bus
PC/104 expansion modules can be stacked with the MiniModule SIO, avoiding the need for card cages and
backplanes. PC/104 expansion modules can be mounted directly to the PC/104 bus connector of the
MiniModule SIO with an inter-board spacing of ~0.60 inches so that a 3-module system fits in a 3.6 x 3.8 x
2.4 inch space. See Figure 2-1.
