The Kontron SBC-845D-VEA is a full-size PICMG single board computer built on the Intel 845D chipset for demanding industrial applications requiring reliable operation in harsh environments. It accommodates Intel Pentium 4 processors up to 2GHz with a 400MHz Front Side Bus, supports up to 2GB of DDR SDRAM with ECC capability, and integrates an ATI M6 3D graphics controller with 16MB dedicated DDR SDRAM. The board provides comprehensive I/O connectivity including Fast Ethernet, three USB ports, two serial ports, parallel port, IrDA, and floppy controller, plus onboard storage interfaces for up to four HDDs via Enhanced PCI IDE with Ultra DMA/33/66/100 support and a Disk-on-Chip socket.
