Examples of Applications

• Ideal for hexapod walkers, quadruped robots, robotic arms, and other advanced robotics projects requiring simultaneous control over many servos.

• Receives feedback from Servos about speed, position, operating mode, torque lock, etc. This is ideal for advanced robotics projects that require automatic closed-loop control.

UART Serial Bus Control | Up to 253 Serial Bus Servos at a Time

Controlling too many servos at a time may require an external power supply source.

Types of Compatible Servos

6V ~ 12V Operating Voltage

Make sure to match the operating voltage with the Servo input voltage. For example, the SC15 Servo is 6V ~ 8.4V compatible The DC input voltage of the driver board should be within this range, i.e., 6V to 8.4V.
