* The Smart6818 CPU board is a Octa-Core Cortex-A53 CPU board designed and developed by FriendlyELEC for industrial applications. As a successor of the Smart210 CPU board it uses the Samsung Octa-Core Cortex-A53 S5P6818 SoC with dynamic frequency scaling up to 1.4GHz. The standard Smart6818 CPU board has 1GB DDR3 RAM and 8GB eMMC. It support software power-off, and RTC alarm power-on functions. In addition its Gbps Ethernet and audio jack make it suitable for various industrial applications.
* The Smart6818 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 FriendlyELEC 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 Smart6818 CPU board's Gbps Ethernet.In addition, Smart6818 is pin to pin compatible to the [[Smart4418]] CPU board.
* For more details about the Smart4418/6818 SDK carrier board V1606 refer to [http://wiki.friendlyelec.com/wiki/index.php/Smart4418_SDK Smart4418/6818SDK 1606].

:Note:
::#RTC backup current is 3.35uA.
::#VDD_5V: Supply voltage, range:4.7 ~ 5.6V. We recommend a 5V/2A(MAX) power. You can lower the clock to decrease the power consumption. When the clock is lowered by 200MHz the power consumption roughly decreases 0.5W .
::#BOOT_CS: Boot chip selection. When it is not connected or pulled up the board boots from eMMC otherwise it boots from SD card
::#NRESETIN: Reset input. Activated when it is low. A reset signal is input to CPU from this pin
::#NRESETOUT: Reset output. Activated when it is low. CPU's reset signal outputs to this pin.
::#RTC_BATT: RTC's input, direct connection to a 3V power source. If the CPU board is powered on the RTC seat is powered by 3.3V external power otherwise when the  CPU board is not powered on it is powered by the RTC battery.
::#ADC1~7: CPU internal ADC, 12-bit, 7 channels 1~7, range:0 ~ 1.8V
::#10/100M Ethernet mode: LAN_MDI1_N/P=RX-/+, LAN_MDI0_N/P=TX-/+, four pins connected to RJ45
::#10/100/1000M Ethernet mode: LAN_MDI0_N/P~LAN_MDI3N/P, all eight pins connected to RJ45
::#MMC0 and MMC1 must be pulled up on the carrier board, even if peripherals are not connected

==Notes in Hardware Design==
===EEPROM===
* The Smart6818 CPU board has an EEPROM(model: 24AA025E48T-I/OT) with a unique MAC. This EEPROM is connected to I2C0 and its address is 0x51 therefore some EEPROM chips cannot be connected to I2C0 which will cause conflicts of addresses.
* In our tests these EEPROM chips cannot be connected to I2C0: 24C04, 24C08 and 24C16. There chips which we tested can be connected to I2C0: 24C01, 24C02 and 24C256
* For more details about EEPROM address issues refer to http://www.onsemi.com/pub_link/Collateral/CAT24C01-D.PDF
