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 Specifications Torque 25kg.cm@12V Rotation Angle 360° (0~4095) Position Sensor Resolution 0.088° (360°/4096) Mechanism Limit Angle No Limit Working Voltage 6 ~ 14 V (typ. 12V) Gear High-precision metal gear No-Load Speed 0.167sec/60° (60RPM) @12V Encoder Type 12 Bits magnetic encoder ID Range 1 ~ 253 Baudrate 38400bps ~ 1Mbps (1Mbps by default) Feedback Position, Load, Speed, Input Voltage, Current, Temperature No-Load Current 200mA@12V Locked-Rotor Current 2.7A@12V KT 9.26kg.cm/A Resources * Product Wiki * User Manual Package Contents * 1x 25kg Serial Bus Servo * Screws * Aluminium Servo Wheels * Servo Cable * 3-pin Cable https://elecena.pl/product/25745431/st3020-serial-bus-servo-25kg 2024-04-23 https://elecena.pl/product/25745431/st3020-serial-bus-servo-25kg 2024-09-18 https://elecena.pl/product/25745431/st3020-serial-bus-servo-25kg 2024-11-29 https://elecena.pl/product/25745431/st3020-serial-bus-servo-25kg 2024-11-30 https://elecena.pl/product/25745431/st3020-serial-bus-servo-25kg 2025-02-13 https://elecena.pl/product/25745431/st3020-serial-bus-servo-25kg 2025-08-06 https://elecena.pl/product/25745431/st3020-serial-bus-servo-25kg 2025-11-28 https://elecena.pl/product/25745431/st3020-serial-bus-servo-25kg 2025-11-29
