Im looking into getting the L9110S Motor Driver. I need to control 4 motors between 4.5v and 6v. The issue I am running into is how the motor driver is powered. It looks like most people power it directly from the GPIO/Breadboard? Example Video. But im also told that connecting things to the Pi like that is a bad idea, especially with motors.
tl:dr-> This driver only takes one power source, should that be from the Pi/breadboard? Or an external battery (I have a 4 AA battery tray right now).
