Maybe I don't understand... but plug in your servo to your ezb4 and find out. Then centre it with ezb builder then attach your sonar the way to want it to be.... then you're done...

okay thanks

Patrick, if that is a picture of the servo you are asking about, you need a voltage regulator. It is a 6v servo. If you plug it directly into the EZ-B with a Lipo battery or a 6AAA battery pack you will burn it out.
