IEI Integration ROCKY-3786EV-RS-R40 10/100 Mbps LAN, PICMG Socket 370 Base VGA Single Board Computer

The IEI Integration ROCKY-3786EV-RS-R40 is a full-size PICMG 1.0 compliant single board computer engineered for industrial embedded applications. Built on Socket 370 architecture, this SBC accepts Intel Pentium III, Tualatin, and Celeron processors operating at FSB speeds of 66/100/133 MHz. The integrated Intel 815E chipset delivers VGA graphics output at resolutions up to 1600×1200 with 8-bit color depth, while dual 168-pin SDRAM sockets support up to 512 MB PC133 memory. On-board connectivity includes 10/100 Mbps Ethernet, dual RS-232 serial ports, one parallel port (SPP/EPP/ECP), optional USB 2.0 support, IrDA, and AC’97 audio. Storage flexibility spans two ATA/100 IDE channels, two SATA channels (150 MB/s), one Compact Flash Type II socket, and floppy drive support. A software-programmable watchdog timer (1–255 seconds) ensures system reliability. Operating range spans 0°C to 60°C with power consumption at 5 V @ 7.6 A and 12 V @ 230 mA (1 GHz CPU, 256 MB RAM). The board measures 174 mm × 147 mm × 35 mm and weighs approximately 0.99 lbs.
