Yahboom YB-SD15M 15kg Serial Bus Smart Servo + Driver Debugging Board Kit for Robotic Arm Joints

Overview

Yahboom YB-SD15M is a 15kg serial bus smart servo (serial bus smart servo) designed for robot/robotic arm joints. It uses alloy/metal gears with metal bearings and an imported high-precision potentiometer for angle feedback. Control is via UART serial port instructions, and multiple servos can be cascaded using a 3-pin PH2.0 interface with an anti-reverse connection design. Angle readback, adjustable rotation speed, and configurable servo ID are supported. A matching driver debugging board is provided to simplify setup and PC-based parameter configuration.

Key Features

• 15KG Serial Bus Servo; special for robot/robotic arm.
• Alloy/metal gear set and metal bearings to reduce wear and friction; rotates smoothly.
• Imported high-precision potentiometer used for angle feedback (high linearity/progress for stable motion).
• Angle readback supported (servo angle feedback).
• ID recognition / bus communication: each servo has an ID (default 1), configurable; single-bus communication; baud rate 115200.
• 3-pin PH2.0 serial bus interface with anti-reverse connection design; supports cascade wiring (multiple servos).
• Supports parameter configuration including rotation speed and position deviation via servo debugging software.
• With main and auxiliary metal rudder disc (more durable and wear-resistant).
• Double-axis fixed design: power output shaft (PTO shaft) + auxiliary fixed shaft for more stable joint movement.
• Driver debugging board provides two parallel bus servo drive interfaces, plus USB and DC power input.
• Reference control codes/resources are provided for Raspberry Pi, Jetson Nano, UNO, Micro:bit, STM32 MCU, and 51 MCU.

Details

Designed for robot joints, the YB-SD15M combines durable metal gears with potentiometer angle feedback and simple 3pin bus wiring.

Reference control resources help you get started quickly across popular boards, from Raspberry Pi and Jetson Nano to Arduino and STM32.

Core hardware details focus on smooth, long-life motion: metal bearings, alloy gears, and high-linearity angle feedback.

Angle readback and configurable IDs make multi-servo bus control easier, while the dual-shaft design improves joint stability.

Ideal for coordinated robot-arm movement, including synchronized master/slave setups and multi-joint control on one bus.

PC debugging software supports quick setup tasks like changing servo ID, tuning speed, and correcting position offset.

Mechanical drawings and key parameters provide sizing guidance for integrating the servo into compact joint structures.

The included driver board adds convenient USB connection and dual interfaces for bus-servo wiring during testing and setup.

Tutorial links, software, and documents are provided to support wiring, configuration, and serial command control.

Optional fixing brackets help mount the servo securely when extending the output shaft or building custom linkages.

A shaft bracket option supports extended structures and more stable mounting for robot arm and joint builds.
