Yahboom YB-SD35M 35KG·CM Serial Bus Smart Servo Kit + Driver Debugging Board for Robotic Arm UART

Overview

This serial bus smart servo kit includes the Yahboom 35kg smart serial bus servo (YB-SD35M) and a driver debugging board for PC and MCU control in robotic arm and bionic robot joint applications. The servo supports convenient cascading on a single bus, 35kg·cm large torque, and a wide rotation range (0–270°, specification: 270° ±10°). It uses a high precision potentiometer for angle feedback, plus stainless steel gears and bearings for durability. Three HY2.0-3Pin interfaces (left/top/right) allow flexible wiring from multiple directions.

Key Features

• Serial bus cascading: Multiple servos can be connected in series via an anti-reverse interface to reduce wiring complexity.
• 35kg·cm torque and 270° rotation (specification: 270° ±10°).
• Angle feedback: Reads back steering angle / joint position to reduce the difficulty of robot and robotic arm motion design.
• ID identification & bus communication: Servo ID range 1–250 (default 1); communication baud rate 115200.
• PC servo debugging software: Supports setting servo ID, rotation speed, position deviation, etc. (designed to be used with the Yahboom driver debugging board).
• Three parallel servo interfaces on the driver board: 3-pin HY2.0 interfaces help prevent reverse connections.
• Mechanical structure: Stainless steel bearing set and stainless steel gear set; black oxidized metal middle case for heat dissipation.
• Dual-shaft stabilization: Power output shaft plus auxiliary fixed shaft; includes main (aluminum alloy) and auxiliary (plastic) steering wheels.
• Multi-platform code resources are provided for Raspberry Pi, Jetson Nano, Arduino (UNO), micro:bit, STM32 MCU, 51 MCU, and K210.
• Provides 35kg smart serial bus servo 3D model files.

Details

High-torque serial bus smart servo designed for robotic arms and bionic robot joints, with convenient single-bus cascading.

Multi-platform code resources help you control the servo from popular SBCs and MCUs during prototyping and integration.

35kg·cm rated torque supports heavier robot links and higher-load joint designs.

Three-direction HY2.0-3Pin ports make cable routing easier in tight frames and multi-joint assemblies.

Connect multiple servos on one bus to simplify wiring and expand multi-joint control.

Internal feedback and durable metal drivetrain components improve positioning stability and long-term reliability.

Angle feedback plus ID-based communication lets each joint be addressed and monitored over the same serial bus.

Useful control modes support coordinated motion learning, teaching, and multi-servo synchronization.

PC software simplifies setup—adjust ID, speed, and position parameters before deploying to your controller.

Dimensions and key specifications help with mechanical planning, and 3D files speed up CAD integration.

Use the driver debugging board to connect the servo to a PC or MCU for configuration and testing.

Documentation and example projects cover wiring, cascading control, and code for several common platforms.
