PC/104 Single Board Computers for Stackable Embedded Systems

PC/104 Single Board Computers

Designed for rugged, space-constrained environments, our PC/104 SBCs use a compact stack-through module design that eliminates the need for a traditional backplane, providing strong resistance to shock and vibration alongside straightforward modular expansion. With long-term availability, wide temperature support, and backwards compatibility with ISA-style buses, they remain a trusted choice for both new embedded designs and the modernisation of legacy systems, in a variety of industries including rail, defence, industrial manufacturing and automation.

Learn More About PC/104 Single Board Computers

A PC/104 SBC is a compact embedded board following a well-established stackable module standard. Rather than using a traditional backplane, PC/104 boards connect directly through stack-through bus connectors, allowing you to build up a complete system by layering boards on top of one another. This approach keeps wiring simple, reduces enclosure space requirements, and makes the overall assembly mechanically robust.

The PC/104 stack-through design allows additional functionality to be added simply by inserting another board into the stack. Extra digital I/O, legacy serial ports, fieldbus cards, or specialist communication modules can all be incorporated this way, without redesigning the base platform or adding complex wiring. This makes it straightforward to expand or adapt a system over time as requirements change.

Yes. PC/104 boards are specifically engineered for demanding conditions. Industrial-grade components, wide operating temperature options, and the inherent mechanical security of the stacked connector design give them strong resistance to shock, vibration, and electrical noise. This makes them well suited to deployments in rail vehicles, defence systems, outdoor industrial machinery, and other environments where standard embedded formats would struggle.

Yes. We can supply PC/104 boards as complete, application-ready stacks rather than loose modules. At our UK facility we fit processors, memory, storage, and any interface or expansion cards you require, then install and test your chosen operating system and software image. The finished stack arrives labelled, documented, and ready to bolt into your chassis, reducing setup time, cabling effort, and simplifying integration into both new and legacy embedded systems.
