Feetech STS3250 12V 50kg.cm 360° Magnetic Encoder Dual-Shaft TTL Servo

The Feetech STS3250 is a 12 V TTL serial bus smart servo with a coreless motor, steel gearbox and double output shaft in an aluminium alloy shell. Its 12-bit magnetic encoder handles 0–360° absolute positioning as well as multi-turn continuous rotation, making it a strong joint servo for robotic arms, quadrupeds and automation rigs.
