Bus Servo Driver Board

Product Overview

The JUXI Bus Servo Adapter is an all-in-one serial bus servo control solution specifically designed for LeRobot SO-ARM100/101 robotic arms and multi-servo robotic projects, eliminating the hassle of complex wiring, separate power supply circuits, and low-level control development for servo-driven robots. Integrating both servo power supply and control circuitry on a single compact board, it supports up to 253 serial bus servos with real-time data feedback (position, speed, torque, operating mode), features 7~12.6V wide voltage input matching most mainstream bus servos, and has pre-calibrated mounting holes that fit directly onto SO-ARM100/101 3D printed parts. With plug-and-play Type-C connectivity and full compatibility with Raspberry Pi, Jetson, RDK and other main controllers, it is the ideal control module for embodied intelligence and robotic development.

Key Advantages

  • Officially Compatible with LeRobot SO-ARM Series

    Precisely calibrated mounting holes perfectly match the 3D printed parts of SO-ARM100/101 robotic arms, no modification required, can be installed directly in 2 minutes, saving custom integration time for LeRobot developers.

  • Control Up to 253 Bus Servos Simultaneously

    Solves the problem of complex wiring and insufficient I/O ports when controlling multiple servos, uses a single bus connection to control up to 253 servos with real-time data feedback, perfect for multi-joint robots like robotic arms, quadruped/hexapod robots.

  • 7~12.6V Wide Voltage Input with Integrated Power Supply

    Supports direct power supply to servos via DC 5521 interface, input voltage can be adjusted according to servo requirements (7V for standard servos, 12V for high-torque servos), eliminates the need for separate power supply modules.

  • Plug-and-Play Type-C Connectivity

    Connect directly to mainstream controllers (Raspberry Pi, Jetson, RDK, PC) via Type-C USB cable, no complex driver installation required, enables servo control and data feedback out of the box, speeds up project prototyping.

  • Full Real-Time Data Feedback

    Supports reading servo position, speed, torque lock status and operating mode (servo mode / servo motor mode), ideal for advanced closed-loop control projects requiring high precision.

  • Added TVS Protection Circuit

    Provides overvoltage and overcurrent protection for the circuit, effectively preventing damage to the driver board and connected servos from voltage spikes, ensuring stable operation in complex environments.

  • Compatible with Most Mainstream Bus Servos

    Supports nearly all serial bus servos available on the market, offering maximum flexibility for different project requirements.

  • Ideal for Embodied Intelligence Drive Modules

    Specially optimized for embodied intelligence development scenarios, providing stable and reliable servo control solutions for various intelligent robot projects.
