3205_1 Towerpro MG91 Micro Servo, 3205_1

£16.15 £13.46

This compact servo has slightly more torque than it's predecessor the MG90.


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.
