Product details

This is a programmable ST3020 360° bus servo with up to 25 kg*cm of 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 25 kg*cm, it has a robust metal gearbox. The serial bus servos provide various feedback signals 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

Features:

  • Programmable serial bus servo
  • Metal gearbox
  • 25 kg*cm torque at 12V
