ST3025 40kg Serial Bus Servo

This is a programmable ST3025 360° Bus Servo with up to 40Kg*cm torque. Up to 253 of these servos can be connected in series via the UART interface to perform complex tasks, for example in robotics. To withstand the loads of up to 40kg*cm, it 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!
