DFRobot Serial Bus Servo Driver Board

DFRobot Serial Bus Servo Driver Board is a compact, high-performance controller engineered to manage up to 253 ST/SC series bus servos for complex robotic systems. This board features USB and UART communication interfaces and acts as a central bridge between a host controller and the servo network. The driver board operates on a supply voltage of 9VDC to 12.6VDC. This board's primary strength is its ability to read real-time feedback on each servo's angle, load, and voltage, in addition to transmitting orders. The driver board's complete integration of power management and bi-directional control circuitry streamlines the development of advanced robotics from multi-axis robotic arms to sophisticated legged robots. Typical applications include multi-DOF robotic arms, advanced legged robots, interactive art and animatronics, custom pan-tilt systems, and rapid prototyping.

Features

  • High-capacity servo control
  • Flexible dual communication interfaces
  • Real-time data feedback
  • Simplified and stable power integration
  • Advanced servo configuration

Applications

  • Multi-DOF robotic arms: build high-precision arms for pick-and-place tasks or automation, using real-time feedback for closed-loop control
  • Advanced legged robots: engineer sophisticated hexapods, quadrupeds, or humanoid robots that require dozens of synchronized, high-torque leg movements
  • Interactive art and animatronics: create dynamic sculptures or characters where numerous servos need to move in perfect harmony
  • Custom pan-tilt systems: develop high-capacity camera gimbals or sensor arrays for complex tracking and surveillance applications
  • Rapid prototyping: quickly prototype and test complex machinery that relies on precise, multi-point actuation before moving to final designs
