Curtiss-Wright / DY-4 SVME-183-0610 Single-Board Computer

The Curtiss-Wright / DY-4 SVME-183-0610 is a single-board computer engineered for aerospace, defense, and harsh industrial environments. It combines dual Freescale Power Architecture MPC7447A/7448 processors with AltiVec technology to deliver signal processing in a compact 0.8" VME slot footprint. Configurable in air-cooled or conduction-cooled variants, the SVME-183-0610 integrates multiple I/O standards and avionics-grade system management for deployments.
