The Smart4418 CPU board is a quad core Cortex A9 CPU board designed and developed by FriendlyARM for industrial applications. As a successor of the Smart210 CPU board it uses the Samsung Quad Core Cortex-A9 S5P4418 SoC with dynamic frequency scaling up to 1.4GHz. The standard Smart4418 CPU board has 1GB DDR3 RAM and 8GB eMMC. It has the AXP229 PMU enabling software power off/on and wake-up functions. In addition its Gbps Ethernet and audio jack make it suitable for various industrial applications.

The Smart4418 CPU board has 2.0mm pitch double row pin headers(P1, P2 and P4) containing 174 pins in total. These pins contain most popular interface pins. By default we have P1 and P2 soldered on the board and leave P4 for users' applications. It works with various FriendlyARM LCDs e.g. 3.5"LCD, 4.3"LCD, 5"LCD, 7"LCD and 10.1"LCD.

In addition we have a Smart4418/6818SDK carrier board which enables the Smart4418 CPU board's Gbps Ethernet.In addition, Smart4418 is pin to pin compatible to the Smart6818 CPU board.
