ST3020 25kg Serial Bus Servo

This is a programmable ST3020 360° Bus Servo with up to 25Kg*cm torque. Via the UART interface, up to 253 of these servos can be connected in series to perform complex tasks, for example, in robotics. To withstand loads of up to 25kg*cm, the servo has a robust metal gear. The Serial Bus Servos provide various feedbacks such as position, load, speed, and input voltage in real-time.  

Attention: This servo cannot be controlled via PWM like standard servos, but via UART!  

Recommended accessories for control:  

• ESP32 Serial Bus Servo Driver Expansion Board
• Serial Bus Servo Driver Adapter (A) USB/UART
