Q: I have other ODROID board. Is it upgradable to ODROID-XU4? No.

Can I get PCB layout file and gerber file?

No. The ODROID project is not a full open source hardware.

We release the schematics PDF only.

Q: Can I get data sheet for all parts?

No. Available data sheets are all linked on our website. Others might need NDA process with chip makers.

Q: Can you test it to make sure that it is suitable for SOMETHING?

If you want to use it for something that we haven’t tested, and that it’s not intended for (i.e. anything but the educational work we’re planning for it), then that development work is up to you. But a lot of community members will try to answer for your question.

HDMI-DVI converter may work with many DVI monitors but a few of them will not work due to compatibility issue.

We recommend 9inch HDMI LCD kit with capacitive touch screen if you want to develop the modern user interface.

There is no analog VGA/TV port.

Yes.

It is possible with USB-SPDIF interface. But it works with only XBMC on Ubuntu.

Android platform doesn't support the 5.1ch pass-through.

Q: Is there any I2S port to connect an external DAC?

Yes. But we have no firm plan/schedule to make a DAC board.

Stockage

Q: What is the eMMC module?

NAND flash based storage IC is mounted on our custom PCB for easier upgrade/replacement.

It is much faster than SD card.

Transfer rate of eMMC 5.0 is 140MB/sec approx. in the real world, while SD-class card is only 10~20MB/sec approx.

Q: Do you have SATA port?

We support the SATA interface via SuperSpeed USB 3.0

USB 3.0 to SATA interface kit works with 3.5inch and 2.5inch HDD/SSD.

Average transfer rate is 140MB/sec approx.

Alimentation

Q: Which power adaptor should I use?

We recommend 5V 4A adaptor. Inner diameter is 2.1mm, outer diameter is 5.5mm. Center is Positiver an Outer is Negative. Normally ODROID-XU4 consumes about 1~2Amp in most cases. But it can go up to 4A when the computing load is very high with a few USB devices.

Logociels

Q: What operating system (OS) does it use?

We recommend Android and Ubuntu as our default distribution. The OS is stored on the SD card or eMMC.

Yes. Boot loader, Kernel and Android platform source code are available. But the GPU user-land drivers are library(binary) format.

Q: Do I need to patch for optional accessories that purchased from this website?

No. They will work just out-of-box.
