## Key Features
The PC/104 form factor (90.4 mm × 90.8 mm) ensures dense module stacking and compatibility with a broad ecosystem of expansion modules. Dual memory architecture supports both volatile DRAM/SDRAM and persistent Flash storage. Multiple serial protocols—RS-232, RS-422/485, and TTL—enable flexible industrial and embedded communications. The integrated Ethernet controller provides 10/100 BaseTx connectivity without external components.
## Typical Applications
• Remote data acquisition
• Communications gateways
• Industrial control systems
• Real-time embedded computing in confined spaces
## Compatibility & Integration
Supports ROM-DOS, MS-DOS, Windows CE, Windows 95, and embedded Linux (AEL). Development kits include technical documentation and installation media. Compatible with all standard PC/104 expansion modules.
