PC/104 Overview
PC/104TM is a stackable, embedded computer standard with a compact footprint and stackable bus architecture. Unlike a regular desktop PC which uses a backplane, PC/104 modules mate together via stackable ISA, PCI, and PCIe bus connectors. PC/104’s success in embedded applications is namely due to:
| COMPACT SIZE | 3.6 BY 3.8 INCHES (90 X 96 MM) MODULE SIZE |
| Self-Stacking | Expands Without Backplanes or Card Cages |
| Rugged, Reliable Connectors | Reliable in Harsh Environments; 1000+ Mating Cycles as Compared to <100 for COMs |
| Four-Corner Mounting Holes | Assymetrical Layout with Increased Resistance to Shock and Vibration |
| Fully PC Compatible | Reduced Development Costs and Time-To-Market |
PC/104 Bus Evolution
PC/104 stackable embedded PCs have followed the desktop PC leveraging on the hardware and software support developed for this popular platform. (Click form factor below for more details).

Custom SBCs & Peripherals For Optimal Size & I/O Configurations
Space constrained solutions can be optimized by way of custom I/O boards that help collapse multiple I/O boards on the stack down to one board as illustrated in the example at right with an oversized I/O peripheral card. Alternatively, custom, single board SBC solutions can also be created by ADL Embedded Solutions for optimal size and I/O configurations.
