Block Diagram and Schematic

ODROID-XU3 is a new generation of computing device with more powerful, more energy-efficient hardware and smaller form factor.
Offering open source support, the board can run various flavours of Linux, including the latest Ubuntu 14.04 and the Android 4.4.
By adopting e-MMC 5.0 and USB 3.0 interface, the ODROID-XU3 boasts fast data transfer speed, a feature that is increasingly required to support advanced processing power on ARM devices that allows users can fully experience an upgrade in computing such as faster booting, web browsing and 3D game experience.

Schematics and drawings are available here.

LED Indicators

RED LED(LED2)- Power

  • ON when it is Hooked up to 5V power.
  • OFF when it is not Hooked up to 5V power.

3 colors LED(LED1)

On bootloader

  • Green is solid on when bootloader is working

On Kernel

  • Blue is blinking when Kernel is running(heart beat).
  • Green is blinking when the eMMC is being accessed.
  • Red is blinking when the MicroSD is being accessed.
