What is PC/104?
PC/104 is a standardized, compact, and rugged form factor for embedded computing systems. It defines a stackable, modular architecture where boards are connected via a 104-pin connector, eliminating the need for a traditional motherboard and backplane. This design is renowned for its high reliability, low power consumption, and exceptional resistance to shock and vibration, making it ideal for space-constrained and harsh industrial environments.
Key Specifications and Technical Details
The PC/104 standard specifies a board size of 3.550 x 3.775 inches (90 x 96 mm). Its defining feature is the self-stacking bus, which uses reliable pin-and-socket connectors. Key technical aspects include:
-
Form Factor: Extremely compact and stackable.
-
Bus Interface: Originally based on the ISA bus, with evolved standards like PC/104-Plus (adding PCI) and PCI/104-Express (adding PCIe).
-
Ruggedness: Designed for extended temperature ranges and high mechanical stress.
-
Power: Typically operates on +5V DC, with low overall power draw.
-
Expansion: Modules for CPU, I/O, networking, and data acquisition can be stacked to create a custom system.
Applications and Use Cases
PC/104 systems are deployed where reliability and size are critical. Common applications include:
-
Industrial Automation & Control: Machine control, PLCs, and robotics.
-
Transportation: Railway, aviation, and automotive telematics and control systems.
-
Military & Aerospace: Ruggedized computing for field deployments and avionics.
-
Medical Devices: Imaging systems and portable diagnostic equipment.
-
Digital Signage & Kiosks: Reliable operation in public spaces.
PC/104 vs. Modern Compact Form Factors
While PC/104 excels in ultra-rugged, modular applications, modern industrial systems often use more integrated, cost-effective form factors for many use cases.
| Feature | Traditional PC/104 | Modern Industrial Mini PC |
|---|---|---|
| Form Factor | Stackable modules (90mm x 96mm) | Integrated, sealed chassis |
| Ruggedness | Excellent (designed for harsh env.) | Very Good (fanless, wide temp.) |
| Performance | Varies by module; can be limited | Typically higher, modern CPUs |
| Deployment | Custom stack assembly | Plug-and-play, pre-configured |
| I/O Flexibility | High (modular expansion) | Fixed, but commonly sufficient |
| Total Cost | Higher (modules, assembly) | Often lower |
