Feetech STS3032 6V 4.5kg.cm 360° TTL Serial Bus Servo

The Feetech STS3032 is a compact 6 V TTL serial bus servo with a full aluminium alloy case, coreless motor and metal gearbox. At 20 g with 4.5 kg.cm of stall torque, it suits small robot joints, grippers and other light-load positioning jobs where several servos share one bus.

Key features

• 12-bit magnetic encoder for 360° positioning, with servo mode and motor mode for continuous rotation

• Fast 0.09 s/60° no-load speed at 6 V

• Overload and over-current protection

• Reports load, position, speed, input voltage and temperature over the bus

• 23.2 × 12.1 × 28.5 mm body with a 25T spline and 200 mm lead
