  • Page 6: Chapter 1 • Welcome

    Some of the modern operating systems that run on the ODROID-XU4 are Ubuntu, Android, Fedora, ARCHLinux, Debian, and OpenELEC, with thousands of free open-source software packages available. The ODROID-XU4 is an ARM device, which is the most widely used architecture for mobile devices and embedded 32-bit computing.

    XU4 also includes a 40-pin GPIO port, an external RTC battery connector, a USB-UART serial console port, an eMMC module connector, and a dedicated slot for a microSD card. For more details, refer to the ODROID-XU4 introductory videos https://youtu.be/wtqfC9v0xB0 https://youtu.be/lUchfyTpOjU...

DC plug cable If you have a 5V DC 4A PSU which does not have the required plug, you can cut off the plug from such a power supply.
  • Page 10: Monitor

    Chapter 1 This cable is also available from Hardkernel, and may be paired with the SmartPower peripheral, which is an excellent bench power supply with variable voltage. Monitor The XU4 offers an HDMI port for connecting an HDMI-com- pliant monitor. It is recommended to use the Hardkernel supplied HDMI cable, but many other high quality standard cables should also work.

    30 sec- onds. According to our testing, most Sandisk microSD cards don’t cause a long boot delay. The ODROID-XU4 model is compatible with a wide array of microSD cards, but class 10 cards or above are highly recommended.
  • Page 14 The 30-pin GPIO port can be used as GPIO/IRQ/SPI/ADC, and the 12-pin GPIO port can be used as GPIO/I2S/I2C for electronics and robotics. The GPIO pins on an ODROID-XU4 are a great way to inter- face with physical devices like buttons and LEDs using a lightweight Linux controller.
  • Page 15: Heat Sink And Fan

    Some owners prefer that the temperatures do not reach such high levels and install a heat sink, which is available from the Hardkernel store. Heat transfer from components to the surround- ing air is related to the surface area available to transfer heat to the surrounding air.
  • Page 16: Frequently Asked Questions

    You may boot from either microSD card or eMMC module. Can I buy OS pre-loaded SD card or eMMC? Yes, they are available from Hardkernel as well as other distributors. Can I add extra RAM memory? No. The RAM is not removable or swappable.
  • Page 17 What are the minimum peripherals to run Ubuntu or Android with an ODROID-XU4? The following peripherals are not included with the basic ODROID-XU4 board, but may be purchased separately from the Hard- kernel store, or from a certified distributor: • HDMI monitor for output device & HDMI Cable •...

  • Page 19 No, but you can use a SATA-to-USB bridge device. Which power adapter should I use? The ODROID-XU4 consumes less than 1A in most cases, but it can climb to 4A if many passive USB peripherals are attached directly to the main board. It is recommended to use the Hardkernel 5V/4A PSU or USB-to-DC Plug cable with a 5V/4A charger.
  • Page 20 However, the GPU userland drivers are in binary format due to ARM’s policies. Do I need to patch for optional accessories that are purchased from the Hardkernel store? No, they will work out-of-box with the kernels supplied with the oper- ating system.

    If you refer to the annotated board image, you can see that the XU4 supports two boot media types - microSD card or an eMMC module. They can be obtained from Hardkernel directly, either with Linux or Android, pre-installed. If you purchased one such device and if it has a factory-installed image, you can skip the flashing steps in this section and proceed to the next section.
