    small usb voltage regulator, connects to usb power block and the knob controls the power . small blue led shows power flow . also has a mini usb that seems to do something not yet discovered ? maybe controls earth's gravity ?

    Using this to control the speed of a usb powered cooling fan that was quite noisy. By using the USB Fan Speed Controller Module to reduce the speed of the noisy fan by about 5%, it has made the fan whisper quiet. Great value for money.

    quite dangerous in my opinion with the exposed pins and circuit board. Should've come coated in heat shrink.

    controller module works well for what it's designed for. reasonably good build quality and don't expect it to fail.
