Servo Motor L 6221MG (Metal Gear) (101821)


Get your start in robotics and making things move! The 6221MG is an excellent choice for a high torque, digital metal geared servo. It comes in a standard large size and its metal gears mean when the motor is in a jam, the gears aren’t likely to strip. 

This large servo will rotate up to 60 degrees.  This servo with its metal gears is a little hefty and comes in at 62g, and is a good choice for medium-large sized projects.

Each servo comes with 3 arms and screws and with pre-soldered female wires. When using servos, we recommend using pin 9 or 10, a standard in the Servo library.

It's easy to fry servos, make sure you plug it into your brain correctly.
