Introduction

This is the DFRobot TT Micro DC geared motor with encoder. It is a motor with a 120:1 gearbox and an integrated quadrature encoder that provides a resolution of 8 pulse single per round giving a maximum output of 960 within one round. With an Arduino controller and motor driver, applications for this include a closed-loop PID control or PWM motor speed control. This motor is an ideal option for mobile robot projects. The copper output shaft, embedded thread and reinforced connector greatly extends the motor’s service life.
The encoder interface is compatible with DFRobot’s Gravity interface.
