Litton are an encoder manufacturer, I have a couple of tiny servo's from
an old HP Plotter, which are 19v and have 1000cpr litton encoders.
Encoder wires are red +5v Black 0v Blue and White are the two phases (A&B).

I have tried them on gecko 340's but those drives are overkill for the
motors I have. I'll probably just use the encoders.
