Jumper Settings

If the jumper is connected between SELECT and Vin, the Vin voltage is directly connected to the V+ rail (green) and to the motor drivers. Alternately, if the jumper is connected between SELECT and +3.3v, 3.3v from the internal regulator is fed to the V+ rail and motor drivers. Note that the blue pins are always 3.3v. The jumper can be removed to temporarily disable the motors and the V+ rail.
