• The NanoPC-T3 octa-core single board computer is designed and developed by FriendlyARM for professional and enterprise users. It uses the Samsung Octa-Core Cortex-A53 S5P6818 SoC. Compared to the FriendlyARM NanoPC-T2 the NanoPC-T3 not only has all the T2’s interfaces and ports but also has a more powerful SoC. Its dynamic frequency scales from 400M up to 1.4GHz. The NanoPC-T3 has 8G eMMC onboard, audio jack, video input/output interfaces, built-in WiFi, Bluetooth and Gbps Ethernet port. In addition the NanoPC-T3 has power management, on board porcelain antenna and serial debug port. To avoid overheat issues the NanoPC-T3 has a heat sink with mounting holes.
• The NanoPC-T3 has two camera interfaces: a DVP camera interface and a MIPI-CSI interface, and four video interfaces: HDMI 1.4A, LVDS, parallel RGB-LCD interface and MIPI-DSI interface. It supports RTC and has RTC interface pins. It has four USB ports with two being type A ports and two being 2.54mm pitch pin-headers.
• The NanoPC-T3 supports muitple OS systems e.g. Android5.1, Debian and UbuntoCore+Qt. It is an open source project with rich interfaces and ports. It is born a choice for professional and enterprise users.

5 Notes in Hardware Design

5.1 EEPROM

• The 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
