ST3020 Serial Bus Servo (25kg)

This dual-axis serial bus servo offers high torque and has a 360° high-precision magnetic encoder for accurate angle control within a 360° range, providing an angle resolution of up to 0.088°. Programmable control allows setting any angle as the servo's middle position, and it can be toggled to continuous rotation mode, functioning as a motor or stepper motor. Each servo is equipped with two interfaces for series connection, allowing the control of up to 253 bus servos simultaneously. Servos relay information on a current angle, load, voltage, mode, and other parameters. This servo is ideal for robotics projects requiring closed-loop control, including robotic arms, hexapod robots, humanoid robots, and wheeled robots. Features

* Wide-range voltage input, support 6-14V DC current input, and can be directly powered by 2S or 3S Lithium batteries.

* Large torque, up to 25kg.cm@12v`

* Can be used in series to control up to 253 servos simultaneously (sufficient power is required) and get feedback from each servo.

* 360° magnetic encoder with wider angle control range.

* High precision, the angle control precision is up to 360°/4096.

* The middle position can be set at any angle, facilitating assembly.

* The acceleration and deceleration functions provide smoother motion effects.

* The compact structural design enhances the product's aesthetics.

* The working mode can be programmatically set to either servo mode for angle control or motor mode for continuous rotation
