So I got loads of these motors from a place not to be named, and was wondering what's the mini-board there? As I figured out it's a DC motor, probably 9 or 12 V, but not sure what the the other cables are for? Is that an encoder? How do I hook it up? I'm pretty new at electronics in practice, so any help or speculation would be appreciated
As requested, inserted better picture, took out the gearwheels. the big one appears to have some kind of a magnet, the PCB is screw to the case and I don't have a tool to unscrew it. My main question is which cables do what? blue and brown spin the motor, I tried them out, and there is conductance between red and black. Green is a mystery.
