12/04/2018: since today, the XU4 board is sold WITHOUT the 5V 4A recommanded PSU.
A ultra-powerful fanless nano computer working under Linux or Android
The ODroid-XU4Q is proprelled with the same processor than ODroid XU4, the powerful ARM® big.LITTLE™ technology and HMP solution (Heterogeneous Multi-Processing).
ODROID-XU4Q and XU4 are a new generation of IT peripheral offering more power, an hardware with higher efficiency-power yield and a very compact form-factor.
Thanks to open-source software, the board can execute several version of Linux operating system, including the an Ubuntu version (16.04), Android 4.4 KitKat, Android 5.0 Lollipop, Android 7.1 Nougat.
As it also support the technologies eMMC 5.0, USB 3.0 & Gigabit Ethernet, the ODROID-XU4 board raise the speed transfert to an impressive rate level.
Those hardware improvements offers a great user experience, higher treatment speed, and more especially a better boot time, an improved navigation flow while using internet browser, better network performance et even great time while playing 3D games.
The XU4Q use a passive heatsink to sink out the processor heat. So, there is no rotating fan, so no unpleasant noise generation. However, keep in mind that passive cooling is not as efficient than active cooling (with a fan), so XU4Q may have more difficulties to keep low temperature (compared to XU4). So you should place it into a well ventilated area.
Hardkernel recommend to reduce the CPU frequency to max 1.4 GHz if the system does overheat to easily (which depend on the CPU charge, so the needs of the various software running on the OS).
The XU4 use a very powerful processor wich need an appropriate power supply. Hardkernel strongly recommend a quality 5V DC 4Amp power supply. The PSU is available here on the shop.
A bad quality PSU may cause unstable working or even damage your XU4.
The XU4 is fully comptable with the XU3 (from software point og view)!
The XU4 is more compact and more scalable than a XU3.

For the Makers
- UART, serial data - take care to use a compatible USB-Serial module, logique 1.8 Volts.
- 30 GPIO pins : GPIO / IRQ / SPI / ADC
- 12 GPIO pins : GPIO / I2S / I2C
- Wiring-Pi wiring (please, see the Odroid wiki)
- Logic @ 1.8 Volts, take care! you can use the shifter-shield.
- ODROID-XU4Q board
- Actif fan (already assembled on the heatsink)
A 5V 4Amp power supply and a microSD card or eMMC module (initialized with an operating system) is required to boot up your ODroid XU4 board.
We do recommend to use a eMMC module to store the operating system.
Keep high performances on your XU4
We strongly recommend to use an eMMC module to store the operating system. The performances of this media can reach 140 MB/s while reading (see this comparaison sheet), a throughput quite higher than SD card.
The higher throughput and better access time would improves the boot time, application startup, multitasking, 3D games and offers a cloud access more efficient. So great time and a better user experience.
ODroid XU4 vs Raspberry-Pi
The Pi-2 & Pi-3 are so popular than HardKernel create a comparative chart of Raspberry-Pi et ODroid.
Keep in mind that Rapsberry-Pi and ODroid doesn't share the same technology so comparing them is not necessarily suitable. It is like comparing a super plane and a wonderful car... they are not used on the same "territory".
By the way, the comparison chart is available here.
Here some interesting videos about the ODroid-XU4... and previous version (the XU3).

The ODroid-XU4Q does have several LEDs that can be used to know more about the board status.
- RED led: the board is powered.
- BLUE led: operating system status
- RJ45 - GREEN led : flashing while having a 100 Mbps connection.
- RJ45 - YELLOW led : flashing while having a 1000 Mbps connection.
