CarPC JoyCon Exr can control one onboard LED and two external LEDs.
If you want to control LED with a preset, check Control. If Control is not checked, this preset doesn’t control LED and LED keeps previous configuration.

If Turn Off on Sleep is checked, LED is turned off when the PC goes into sleep mode.
