Expansion Connectors
The Odroid-XU4/3 povides one 30-pin dual row expansion header “CON10”. The location and pinout of these connectors is illustrated blew. All signals on expansion headers are 1.8V except PWRON signal.

OS configuration
If you use Ubuntu 14.04 image, you must consider this.Ubuntu 15.04 image has a proper configuration by default.
The IOBARDUse the IO Expansion Board modules are loaded automatically when the OS boots.
So you need to add the modules into the blacklist to use mores GPIOs.
Open /etc/modprobe.d/blacklist.conf file and add drivername using following syntax:
blacklist ioboard_bh1780 blacklist ioboard_bmp180 blacklist ioboard_keyled
