STS3250 50kg Heavy Duty Smart Servo

The STS3250 delivers 50kg.cm of stall torque in the same standard footprint as the STS3215, so you can upgrade high-load joints without redesigning your build. An all-aluminum case, coreless motor, and steel gearbox handle demanding loads, and dual output shafts allow brackets on both sides. The 12-bit magnetic encoder provides 360° position control, multi-turn continuous rotation, one-key center setting, soft start and stop, and real-time feedback for overload and over-current protection.
