This bridge board is to supply separated 5V power to the ODROID-VU7 and VU7 Plus.
When the computing load of the XU4 board is very heavy, we can observe 0.5~0.6V ripple on 5V rail on the USB host port. The ripple voltage causes visible flickering of the Vu7 and Vu7+ LCD backlight.
To avoid this issue, use this power bridge board as a workaround.
You need to purchase 5V/2A PSU separately.
