ODROID XU4 USER MANUAL
Hardware Tinkering
N
ow that you have been introduced to the XU4 and have become
aware of booting it up with a image, it is time to get acquainted
with its main purpose of creation – to be able to interact with
the external world through the age-old activity of tinkering. While its
design and production is a marvel in itself, it really shines in its use to
interact with the external world, through a slew of breakout-boards and
sensory devices – all under the control of powerful operating systems
like Linux or Android.
Here are the devices covered in this section:
• USB UART Module Kit; Bluetooth Module 2
• ODROID ONE, ODROID-SHOW/SHOW2, and Weather Board
• DC Plug Cable Assembly 5.5mm
• USB audio adapter, USB-SPDIF, and ODROID USB-CAM 720P
• USB GPS Module and board
• USB3 / SATA3 HDD/SSD interface kit
• USB3 / SATA2 HDD/SSD RAID 0/1 enclosure
• Cloudshell, Expansion Board and Shifter Shield
• ODROID-VU7
Always shut-down the XU4 and power it off before attaching or
detaching peripheral devices. The same applies for peripherals that
have their own power supplies. Some unsupported powered peripher-
als, though known to work with the XU4, may not be safe to use if they
leak current back through the USB port, which could damage the XU4.
Always backup your image before attempting to work with any
new peripheral, especially if it requires installation of additional soft-
ware. You can always revert to a known working state, should your
efforts cause issues.
