Servo Metal Gear 30kg.Cm Serial Magnetic Encoder Programmable 360 Degrees Rotation ST3215 (Waveshare)

Out Of Stock



The ST3215 Servo is the perfect companion for robot projects that demand real-time feedback for closed-loop control, including robotic arms, hexapod walkers, humanoid robots, wheeled robots, and more. This remarkable device is armed with a 360° high-precision magnetic encoder, enabling precise 360-degree absolute angle control. But that's just the tip of the iceberg. With programmable controls, you can define any angle as the servo's midpoint, and it's versatile enough to switch between continuous rotation modes, acting as a motor or stepper motor. Notably, it incorporates an acceleration start-stop function for smoother actions.
