It needs the 11-36V motor power. It does not appear to need a 5V supply. It provides a 12V output which you might use to power an Arduino.

Often it helps to find a datasheet for the chip. Unfortunately the ad doesn't mention the chip model and the pictures don't show it. You have three input pins: EN, PWM1 and PWM2. There are only seven possible states for those three pins so by trying them all you should be able to determine what goes Forward, Backward and Disabled.

It does use "external" power from the little documentation I found on google.

This advertisement on AliExpress seems to be for the same device and provides a little more detail on how to use it:
