Dual Serial Bus Servo Driver Boards

This pack supplies two driver boards that merge power delivery and control circuitry for ST/SC series serial bus servos. Each board targets makers and robotics developers who need to drive many servos from a single host without designing custom power distribution. The integrated design reduces wiring and simplifies prototyping for articulated projects.

253 Servo Capacity and Power Options

A single board can address up to 253 ST/SC series servos simultaneously over the serial bus. Power enters through an onboard DC5521 jack or a screw terminal, letting you match the supply to the servo voltage requirements. The bus returns status and feedback from every connected servo, so the host can monitor position, load and error data in real time.

UART and USB Control Limits

Control mode is selected by a jumper: position A enables direct UART communication, while position B routes commands over USB for rapid host connection. The UART path suits embedded controllers and custom firmware; the USB path accelerates PC-based prototyping with the provided SDK. Both interfaces share the same 253-servo address space, so the practical limit is the bus addressing scheme, not the host link.

商品問答

Will this driver board control my existing ST-series servos alongside new SC-series units on the same bus?

Yes, each board supports up to 253 ST/SC series serial bus servos simultaneously, mixing both families on one UART bus.

How can I verify the board is communicating correctly after wiring the DC5521 jack and USB link?

Connect via USB, open the serial monitor, and confirm each servo returns its ID, position, and status packets through the SDK.

Does the package include the USB cable and DC power adapter, or must I source them separately?

The listing covers two driver boards only; USB cables and DC5521 power supplies are not included and must be purchased separately.
