It's aimed at multi-servo robotics projects like robotic arms and multi-legged robots, where coordinated control across several servos matters more than driving a single motor.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Is the Bus Servo Driver Board?\u003c\/h2\u003e\n\u003cp\u003eThe board manages servos running on serial communication protocols such as ST\/SC, converting commands into servo actions through onboard control circuitry. Unlike traditional PWM control, serial bus communication is more efficient and scales better across multiple servos, making it a better fit for robotics builds that need several coordinated joints rather than a single actuator.\u003c\/p\u003e\n\n\u003ch2\u003eDual-Mode UART and USB Control\u003c\/h2\u003e\n\u003cp\u003eThe board supports both UART and USB communication, switchable via an onboard jumper. UART suits embedded integration where the board is driven directly by a microcontroller, while USB mode is plug-and-play, useful for quick desktop debugging and PC-based control without extra wiring.\u003c\/p\u003e\n\n\u003ch2\u003eMulti-Servo Control with Feedback\u003c\/h2\u003e\n\u003cp\u003eMultiple ST\/SC servos can be controlled from a single board, with angle and load feedback available, giving finer control over multi-degree-of-freedom projects than a basic single-servo controller allows. The exact number of servos supported depends on your power supply capacity and bus load.\u003c\/p\u003e\n\n\u003ch2\u003eCompact and Ready for Integration\u003c\/h2\u003e\n\u003cp\u003eAt just 42mm x 25mm, the board stays compact enough for space-constrained robotics builds, with a 2P 3.5mm screw terminal for secure power connections and a 2.5mm 3P terminal for servo wiring.\u003c\/p\u003e\n\u003cp\u003eNote that this expansion board isn't directly compatible with the XIAO nRF54L15 series, since Arduino isn't currently supported on that board. The hardware interface itself is fully compatible, so developers can manually adapt the software if needed, and official software support from Seeed Studio is in development.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable border=\"1\" cellpadding=\"6\" cellspacing=\"0\" style=\"border-collapse: collapse; width: 100%;\"\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible Servo Types\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eST\/SC series serial bus servos\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eServo Control Quantity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMultiple\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eControl Interface\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUART \/ USB\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCommunication Protocol\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSerial bus protocol (ST\/SC compatible)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Voltage Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5-12V DC, dependent on servo voltage\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Supply Interface\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2P 3.5mm screw terminal\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eServo Interface\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2.5mm 3P terminal\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eJumper Settings\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUART\/USB mode switching\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e42mm x 25mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15g\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10°C to 60°C\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I power the Bus Servo Driver Board?\u003c\/strong\u003e\u003cbr\u003e\nConnect power through the onboard 2P 3.5mm screw terminal.
