 * IMX6DL 800MHz SoC (IMX6Q optional)
 * 512MB 32bit DDR3 SDRAM (up to 2GB optional)
 * 256MB NAND FLASH (up to 2GB optional)
 * Gateworks System Controller
 * 2x front-panel Intel i210 GbE adapters with passive PoE support
 * 2x MiniPCIe sockets with USB support
 * 2x front-panel USB
 * 1x rear-panel full-size HDMI connector
 * 1x front-panel bi-color user LED
 * 1x front-panel user pushbutton
