TD-8120MG Digital High Torque Servo Motor Metal Gear 20kg 360° Continuous Rotation

Reference RBD-3230

TD-8120MG 360° Continuous Rotation Digital Servo with 22.8kg.cm torque.
Provides speed-based motion control for wheels, arms, and automation.
Built with all-metal gears and aluminum shell for superior durability.
Water-resistant and compact, ideal for robotics and RC projects.
Operates at 4.8V–7.2V with fast 0.14s/60° response speed.
Compatible with Arduino, Raspberry Pi, and other PWM controllers.

Continuous rotation servos are like regular hobby RC servos but modified to offer speed control instead of position control. They're essentially compact, affordable motors with integrated motor drivers. Add a wheel, and you've got a simple drive system for your robot, controllable with an RC signal or directly connected to a single microcontroller I/O line.
