PC/104 Architecture
The PC/104 architecture affords a great deal of flexibility in system design. You can build a simple system
using only a CoreModule Single Board Computer (SBC) with input/output devices connected to its serial or
USB ports and a Compact Flash card in the Compact Flash socket. To expand a simple CoreModule system,
simply add self-stacking ADLINK MiniModules or 3rd party PC/104 expansion boards to provide
additional capabilities, such as:
• Additional I/O ports
• Analog or digital I/O interfaces
PC/104 expansion modules can be stacked with the CoreModule 435 avoiding the need for card cages and
backplanes. The PC/104 expansion modules can be mounted directly to the PC/104 bus connector of the
CoreModule 435. PC/104-compliant modules can be stacked with an inter-board spacing of ~0.66" (16.7
mm) so that a 3-module system fits in a 3.6" x 3.8" x 2.4" space. See
Figure 2-1 .
One or more MiniModule products or other PC/104 modules can be installed on the CoreModule expansion
connectors. When installed on the PC/104 headers, the expansion modules fit within the CoreModule outline
dimensions. Most MiniModule products have stack-through connectors compatible with the PC/104 Version
2.5 specification. Several modules can be stacked on the CoreModule headers. Each additional module
increases the thickness of the package by 0.60" (15 mm). See Figure 2-1 .
