## Description

This compact motion control board is designed to coordinate ST and SC series serial bus servos in robotics projects, with support for up to 253 servos on a single bus network. It combines power distribution, command transmission and telemetry feedback for multi-axis builds such as robotic arms, walking robots, gimbals and animatronics.USB and UART interfaces make it useful both on the bench and inside a finished robot. USB allows connection to a computer for debugging, configuration and motion testing, while UART provides a straightforward link to embedded controllers and microcontroller-based robotics systems.The board supports bi-directional communication, so your controller can read back servo angle, load, voltage and working mode for closed-loop control and fault monitoring. It also supports programmable servo ID configuration and switching between positional servo mode and continuous motor mode.Power can be connected via either the DC 5.5×2.1mm jack or the 2-pin terminal block. The package includes the serial bus servo driver board x1, hexagonal studs x4, shorting caps x2 and screws x4.Features:Controls up to 253 ST and SC series serial bus servos on a single networkUSB interface for PC connection, debugging, and configurationUART interface for integration with embedded controllersBi-directional communication for reading angle, load, voltage, and working modeSupports programmable servo ID configurationSelectable operating modes: positional servo mode or continuous motor modeDual power input: DC 5.5×2.1mm jack and 2-pin terminal blockDesigned for high-DOF robotic systems and multi-servo synchronizationSpecifications:Servo Compatibility: ST & SC Series Serial Bus ServosMax Servo Count: 253Input Voltage: DC 9-12.6V (Must match servo voltage)Communication: USB & UARTPower Connectors: DC 5.5x2.1mm Jack, 2-pin Terminal BlockKey Functions: ID Programming, Mode Switching (Servo/Motor), Real-time Data Readback (Angle, Load, Voltage)Dimensions: 42 x 33mmWell suited to high-degree-of-freedom robotic arms, hexapods, quadrupeds, humanoid robots, interactive art, animatronics, custom pan-tilt systems and rapid prototyping.
