Product details

This is a programmable ST3215-HS 360° bus servo with up to 20Kg*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 enable the servo to withstand loads of up to 20kg*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
20kg*cm torque at 12V
UART interface
Real-time readout of position, load, speed and input voltage.
Up to 253x switchable in series

Application examples:
Robot arms
Hexapod robot
Wheeled robot
Open source 12-DOF robot dog model
