SO-ARM101 Robotic Arm Servo Motor 7.4V w/ 20 Inch Debugging Wire Reduction Ratio 1/345 Compatible w/ STS3215 Servo

Elevate your robotics, automation, and industrial projects with this cutting-edge 7.4V TTL serial bus controlled servo compatible w/ STS3215 Servo, delivering an impressive 19kg.cm torque and equipped with a 12-bit high-precision magnetic coding sensor for unparalleled accuracy. This versatile servo supports 360-degree continuous rotation while maintaining precise position control over a full 360-degree effective range, making it ideal for demanding applications like robotic arms, CNC machines, and small torque drive systems. With features like daisy-chaining multiple units on a single serial bus, overcurrent protection, multiple working modes, and advanced feedback for parameters such as angle, temperature, voltage, current, and load, the STS3215 ensures reliable performance and easy integration. One-click center position calibration allows for effortless installation at any angle, boosting production efficiency and minimizing maintenance costs. Plus, multi-turn precision control enables absolute position feedback across ±7 turns (expandable to hundreds with resolution adjustments), and acceleration-based start/stop functions provide smoother, more controlled movements. Whether you're building industrial equipment or prototyping robots, this servo combines power, intelligence, and convenience in a compact package. This package includes a 20-inch flexible debugging wire, perfect for probing connections, investigating errors, and simplifying research and prototyping workflows—get started right away with everything you need for seamless debugging and deployment! Package includes: 1 x Servo with accessories 1 x 20" debugging wire

• High-Torque Performance Specs: Operates at 6V-7.4V with peak stall torque of 19.5kg.cm@6V, rated torque of 6.5kg.cm@6V, no-load speed of 0.238sec/60°@6V, running current of 150mA@6V (no load), and stall current of 2000mA@6V—delivering robust power for industrial equipment, robots, and small torque drive scenarios.
• Included 20-Inch Debugging Wire: Flexible wire for effortless probing, error investigation, and connection testing—makes research, prototyping, and troubleshooting significantly easier and more efficient during development.
• Compatibility: Uses on LeRobot SO-101 leader/follower arms. Fully compatible with Feetech ST-3215-C001 and Waveshare ST3215 servo motor.
• One-Click Calibration: Install at any 360-degree position and use one-key calibration (via 40-address input 128) to set the center—exclusive to magnetic encoding for hassle-free setup, improved production efficiency, and reduced maintenance costs (unlike potentiometer servos that require pre-adjustment).
• Advanced Magnetic Encoding: Features a 12-bit high-precision magnetic coding sensor for 360-degree continuous rotation with precise position control over a 360-degree range; supports multi-turn large-angle control with absolute feedback across ±7 turns (expandable to hundreds), retaining position data even after power loss (turns not saved).
• TTL Serial Bus Control: Command signal via digital packet for easy integration; multiple servos can be daisy-chained on the same bus, enabling scalable setups in complex systems like robotics and automation.
