ST3020 Servo - 25kg.cm Wide Range Voltage Serial Bus Servo, High Precision And Large Torque, With Programmable 360 Degrees Magnetic Encoder

This product is a dual-axis serial bus servo with high torque. It incorporates a 360° high-precision magnetic encoder, allowing for angle control within a 360° range and the angle resolution is up to 0.088°.

It can be programmatically controlled to set any angle as the servo's middle position, and it can also be switched to continuous rotation mode as a motor/stepper motor. Each servo has two interfaces, allowing them to be connected in series. In theory, up to 253 bus servos can be controlled simultaneously, and each servo can provide information about its current angle, load, voltage, mode, and other parameters. This servo is suitable for robotics projects that require closed-loop control, such as robotic arms, hexapod robots, humanoid robots, and wheeled robots.

Furthermore, we provide open-source models for this servo model, including hexapod robots, quadruped robots, camera gimbals, and robotic arms. You can download these open-source model files and engineering documents in the #Open Source Model section.
