WaveShare ST3025 40kg Serial Bus Servo

This is a programmable ST3025 360° bus servo with up to 40 kg*cm torque. Up to 253 of these servos can be connected in series via the UART interface to perform complex tasks, such as in robotics. To enable the servo to withstand loads of up to 40 kg*cm, it has a robust metal gearbox. The serial bus servos provide various feedback signals, including position, load, speed, and input voltage in real time.

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