waveshare 25kg.cm 6~14V Wide Range Voltage ST3020 Serial Bus Servo, High Precision and Large Torque, with Programmable 360 Degrees Magnetic Encoder, Two-Way Feedback, Servo/Motor Mode Switchable

Overview 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. Specification Input Voltage: 6V-14V DC Mechanical Limited Angle: No Limit Rotating Angle: 360° (servo mode angle control)/motor mode continuous rotation Baudrate: 38400bps~1Mbps (1Mbps by default) Gear: high-precision metal gear Idling Speed: 0.167sec/60°(60RPM)@12V Position Sensor Resolution: 0.088°（360°/4096） ID Range: 0-253 Locked Rotor: 25kg.cm(347.79oz.in)@12V Feedback: Position, Load, Speed, Input Voltage, Current, Temperature Load Current: 200mAA Locked-rotor Current: 2.7A Dimension: 40.2mm x 20.2mm x 40mm 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. Online Tutorial/Online Document:n9.cl/u72fo Package Content ST3020 Servo x1

• 【UART Serial Bus Control】 Allows controlling up to 253 serial bus servos at the same time. 【Two-Way Feedback】The Servo will provide various feedback like position, load, speed, input voltage, current and temperature in real time. 【Multiple Operation Modes】suitable for more application scenarios.
• 【Easy to use, Large Torque】 Supports 6.0~14V wide range voltage input, and can be directly powered by 2S or 3S lithium batteries. Up To 25kg.cm torque on 12V voltage, suitable for building quadruped robots, hexapod walkers, robotic arms and other robotic projects requiring multiple servos.
• 【360° Magnetic Encoder, High Precision, Longer Lifetime】 Adopts 12-bit high-precision magnetic encoding angle sensor. Compared with the carbon film potentiometer, the angle of the magnetic encoder is enlarged to 360°, and the resolution is increased by 4 times. Since there is a gap and no friction between the magnetic encoder and the radial magnet, the lifetime of the servo is effectively extended.
• 【One Button to Calibrate the Middle Position】 360° installation at any position, one button to set the current position as middle position. Easy to install and debug.
• 【Multi-Loop angle Position control】 Supports angle position control in both positive and negative directions up to 7.5. loops under the default precision setting, but the number of loops will not be saved in case of power loss. Lowering the angle resolution can double the number of control loops.
