It can be used to build wheeled robots, 3D printers, and other projects that require accurate closed-loop speed control or stepper control. It is also suitable for building robot projects such as quadrupeds, hexapods, and robotic arms that require multiple servo motors. Up to 253 servos can be connected in series simultaneously. Features: - Uses a 12-bit high-precision magnetic encoder angle sensor. Compared to carbon film potentiometers, the magnetic encoder offers a full 360-degree usable angle and four times higher resolution. With no physical contact between the magnetic encoder element and the radial magnet, there is no friction, effectively extending the service life of the servo motor. - Adjustable speed and acceleration settings allow for smoother motion control. - Optimized dual-axis steering disc plane spacing results in a more compact structure and improved appearance.
