The GW5520 features the NXP™ i.MX6 Dual Core ARM® Cortex™-A9 SoC processor operating at 800MHz, 512Mbyte of DDR3-800 DRAM, and 256Mbytes of System Flash. Dual Gigabit Ethernet ports allow for multiple wired connectivity options, including VPN. Two Mini-PCIe expansion sockets support any combination of 802.11ac/b/g/n WiFi radios, 4G WiMAX radios, 3G CDMA/GSM cellular modems and other PCI Express peripherals such as the GW16126 LTE CATM1 Cellular card, GW16122 Sub-1GHz radio, GW16130 Iridium Satellite Modem or LoRA radio . The HDMI output extends the GW5520 into wireless video applications. The Gateworks System Controller provides embedded features such as real time clock, voltage and temperature monitor, serial EEPROM, programmable pushbutton switch, and advanced power management with programmable board shut-down and wake-up for remote sensor applications. A wide-range DC input power supply provides up to 16W of power to the Mini-PCIe sockets for supporting the latest high-power radios. Power is applied through a dedicated barrel jack or an Ethernet jack in a Passive Power over Ethernet architecture. Linux OpenWrt, OpenEmbedded/Yocto, and Andriod are supported. The GW5520 is made in the USA and designed for rugged and industrial markets. The dual ethernet ports are the differentiating feature, allowing many 'in and out' data type scenarios (VPN, filtering, WAN/LAN, router etc).
