This Servo Motor has a 360° high-precision magnetic encoder, providing precise angle control within a full 360° range. With a top speed of 106 RPM, it offers flexibility, allowing you to set any angle as the servo motor's middle position. Additionally, it can switch between functioning as a continuous rotation motor and stepper motor mode.

It features built-in acceleration and deceleration functions, helping to provide smoother motion transitions. Each unit has dual interfaces, supporting the ability to connect multiple motors in series. It can control up to 253 bus servo motors simultaneously, with each motor providing real-time feedback on angle, load, voltage, and current operational mode.

Designed for closed-loop control projects, it is ideal for use in robotic arms, hexapod robots, humanoid robots, and wheeled robots. The servo's compact design enhances the aesthetic of any project, while its wide voltage input range (6-12.6V) accommodates direct power supplies from two-cell or three-cell lithium batteries. The servo offers multiple programmable work modes, including a servo mode for precise angle control and a motor mode for continuous rotation, providing adaptability and high performance in various robotic configurations.
