7) D_LED1/D_LED2 (Addressable LED Strip Headers)
The headers can be used to connect a standard 5050 addressable LED strip, with maximum power rating
of 5A (5V) and maximum number of 1000 LEDs.
D_LED1
Connect your addressable LED strip to the header. The power pin (marked
with a triangle on the plug) of the LED strip must be connected to Pin 1 of the
addressable LED strip header. Incorrect connection may lead to the damage
of the LED strip.
For how to turn on/off the lights of the LED strip, please navigate to the "Unique Features" page
of GIGABYTE's website.
Before installing or removing the devices, be sure to turn off the devices and your computer. Unplug
the power cord from the power outlet to prevent damage to the devices.
