The Kitronik Clippable 360 Degree Servo features plastic gears, which although they are not as hard-wearing as their metal counterparts are lighter and suitable for most applications.
The servo is rated to operate between 4.8 - 6 V, and has a max stall torque of 1.5kg.cm@6V. If the clippable servo is being used in micro:bit projects, a separate power supply is required. If you are using the Kitronik Klip Motor Driver, the power can be taken directly from the Klip motor driver board.
