Laguna GW2388-4 Single Board Computer

Laguna GW2388-4 Single Board Computer

A full featured high performance carrier grade quad Mini-PCI SBC for enterprise and residential network applications

The GW2388-4 is designed for a wide range of outdoor applications such as WISP customer premise equipment, Mesh repeaters, WiMAX pico base stations, 3G-routers, wireless point to multipoint bridges and 3G to WiFi routers and gateways. The board features the Cavium® ECONA™ CNS3420 Dual Core ARM11 SoC processor operating at 600MHz, 256Mbytes of DDRII-400 DRAM, 16Mbytes of System Flash, 4Mbytes of Backup and Restore Flash, and two Gigabit Ethernet ports. The board includes four high-power Type III Mini-PCI sockets capable of supporting any combination of 802.11abgn radios, WiMAX radios, and other Mini-PCI peripherals. An optional Mini-PCI adapter is available for 3G CDMA/GSM modem support. The board features a wide-range DC input power supply which can source up to 25W to the Mini-PCI sockets for supporting the latest high power radios. The GW2388 also includes the Gateworks System Controller for providing embedded features such as real time clock, voltage and temperature monitoring, general purpose digital I/O, serial EEPROM, programmable front panel switch, tamper switch and advanced power management with programmable board shut-down and wake-up for remote sensor applications. Power is applied through a dedicated barrel jack connector or either Ethernet jack in a passive power over Ethernet architecture. An OpenWrt board support package is included for Linux operating systems.
