1 Introduction

Overview
Front
Back
  • The NanoPC-T2 quad core Cortex A9 single board computer is designed and developed by FriendlyARM for professional and enterprise users. It uses the Samsung Quad Core Cortex-A9 S5P4418 SoC with dynamic frequency scaling up to 1.4GHz. Compared to FriendlyARM's existing 4418 based boards the NanoPC-T2 has 8G eMMC onboard, audio jack and video input/output interfaces. Compared to its predecessor the NanoPC-T1 the NanoPC-T2 has built-in WiFi, Bluetooth and Gbps Ethernet port. In addition the NanoPC-T2 has power management which the NanoPC-T1 doesn't support. To avoid overheat issues the NanoPC-T2 has a heat sink with mounting posts.
  • The NanoPC-T2 combines all the ports and interfaces the existing FriendlyARM 4418 boards have. Currently it has the most interfaces and ports among all existing ARM boards of this size. Its rich video interfaces and support for HDMI 1080P enable it to work with not only popular display devices but also various FriendlyARM LCDs (both resistive touch and capacitive touch).
  • The NanoPC-T2 is FriendlyARM's most complete solution based on Samsung 4418 for both commercial and industrial applications.

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
