DFRobot DF15RSMG 360 Degree Standard Servo Motor (20kg) for RC Robot

Introduction

This is the most powerful standard servo sized motor from DFRobot so far. The DF15RSMG equips with two pairs of the servo shells. One is a standard shell with four M4 mounting holes. And the other one includes a shell with double bearing which is specially designed for the application of the robot arm or the joints.The shells of this kit are thickened to make it stable enough for motion system.

The torque of this motor is about 19kg.cm at 7.4v power supply.Using the Arduino servo library, you could drive this servo motor easily.To reduce the consumption of your microcontroller, this servo has a lock function for the pulse detection. So driving it to a target position just requires one PPM controlling signal.
