Feetech Dual Shaft Serial Bus Servo STS3020 270 degree 20kg

The STS3020 serial bus servo is a high-performance servo motor designed for precision control in various applications. With a torque of 20kg and an operational angle of 360 degrees, this servo is extremely versatile and can be used in a wide range of advanced applications. Due to the advancement of software in robotics, Serial bus servos are fast becoming the go-to servo for automation applications.

Serial bus servos also allow for telemetry, giving you feedback on the servo position, current, voltage and current output, expanding the control capability of the servos. As serial bus servos communicate using serial communication, multiple serial bus servos can be connected to the same communications port of the host microcontroller which requires only two pins, saving GPIO pins.

Use this servo in robot joint applications such as biped robots, robot arms and more.

To control this servo, it is recommended to use the FE-UR1 Serial Bus servo controller.
