Newport GW6903 Single Board Computer

The GW6903 SBC features the Cavium OcetonTX™ Dual Core ARMv8 SoC processor operating at 800MHz, 1GByte of DDR4 DRAM, and 8GBytes of eMMC System Flash. Two Mini-PCIe half card expansion sockets supports 802.11abgn/ac wireless radios, LTE/4G/3G cellular modems and other PCI Express peripherals. Additional peripherals include a Gigabit Ethernet port and a Type A USB 3.0 port. The Gateworks System Controller provides embedded features such as real time clock, voltage and temperature monitor, fan monitor and control, serial EEPROM, and advanced power management with programmable board shut-down and wake-up for remote IoT sensor applications. A wide-range DC input power supply provides up to 8W to the Mini-PCIe sockets for supporting thelatest high-power wireless radios. Input Power is applied through dedicated connector or the Ethernet port in a Passive Power over Ethernet configuration. Both OpenWrt and Ubuntu Linux Board Support Packages are supported on the ARM Processor. The small size of the single board computer allows it to operate in rugged and industrial applications with limited space. This product is made in the USA making it suitable for military and other secure projects. An IoT Gateway can easily be created by mating the GW6903 SBC with two half card Mini-PCIe radios. Internet of things and mesh systems are a perfect match for this miniature SBC that is only 35x110mm.
