Smart6818 is a board built for industrial applications and is a successor to the Smart210 board. At the heart of the Smart6818 is the powerful Samsung Octa-Core Cortex-A53 S5P6818 SoC which is able to have a dynamic scaling frequency of up to 1.4Ghz unlike the 1GHz provided by Samsung S5PV210 for the Smart210 board.
The Smart6818 board has an interesting 2.0mm pitch double row pin headers (P1, P2, and P4) containing a whopping 174 pins in total. These pins contain pretty popular interface pins. By default, it has the 2 opposites pin rows (P1 and P2) soldered on the board leaving P4 for user’s applications.
The standard version of the board comes packed with 1GB DDR3 RAM and an 8GB eMMC, with support for software power-off and Real Time Clock (RTC) alarm power-on functions. In Linux, the real-time clock alarm can be set or retrieved using /proc/acpi/alarm or /sys/class/rtc/rtc0/wakealarm.
Also, its Gbps Ethernet and audio jack make it super duper suitable for various industrial applications. It works with various FriendlyELEC LCDs such as the 3.5″ LCD, 4.3″ LCD, 5″ LCD, 7″ LCD like a Lenovo tablet and the larger 10.1″LCD screen.

An SDK carrier board is available for the Smart6818 which enables the smart6818 CPU board’s various ports and interfaces. The carrier board has a SATA interface and a mini PCIe interface that supports an external 4G module. One incentive with this board is that it offers compatibility with the Raspberry Pi’s interface.
