The MG91 is a nice small RC servo ideal for projects where size and weight are important.
RC servos are hobbyist remote control servos typically used in radio-controlled models, where they provide actuation for various mechanical systems such as the steering of a car, the flaps on a plane, or the rudder of a boat. These servos are not industrial grade and are not recommended for continuous heavy use.
This servo has slightly more torque than the previous revision. Also, unlike the MG90 the MG91 does not have mechanical stops meaning that an unpowered motor can rotate continuously in either direction but with a single rotation pot, will always snap to the same range when power is reapplied.
The MG91 comes with 3 servo rudder pieces and 1 set of screws.
This servo motor needs to be connected to a servo controller board. If you're looking for higher torque, you should select a servo controller with an external power jack so it doesn't have to rely solely on USB power, which is limited. You can plug this servo directly to any of the boards in the list below by matching the color of the wire with the label on the board. Note that some servos have a white data wire and others have a yellow one- in both cases this wire corresponds to the "W" pin on the servo controllers.
