Key Features
- UART serial bus control: Allows controlling up to 253 SC/ST series serial bus servos at the same time, supports receiving the operating status and various information feedback of each servo
- Compatible Servos: Supports ST/SC series bus servos, and can directly power the servos via DC power jack, supports selecting power supply input according to the servo used
- Supports UART and USB control: Switching the control mode by selecting A or B via the jumper. Two Power supply methods: Onboard DC5521 power jack and screw terminal for easy integration into existing projects
- Easy to use with USB control: Connect the driver board to the host via a USB cable to easily control the serial bus servo and receive data feedback, speeding up the project prototyping process
- Application: Servos will provide various feedback like position, speed, torque lock, and operating mode (servo mode, servo motor mode, etc.) for advanced projects requiring closed-loop automatic control. Ideal choice for building quadruped robots, hexapod walkers, robotic arms and other robotic projects requiring multiple servos
