Overview

The DFRobot Gravity TT Motor Encoders Kit adds wheel rotation feedback to TT-style micro DC geared motors. It uses a non-contact optical method to detect rotation, which helps avoid mechanical wear while providing usable data for speed measurement and motion control.

With a resolution of 20 pulses per revolution, this kit is suited to basic odometry, closed-loop control, and wheel-speed monitoring on small mobile robots. It is designed to work with Gravity-style connections and can be used with Arduino or Raspberry Pi expansion shields.

The package includes the encoder sensors, grating disks, and the mounting hardware needed for installation on compatible TT motor setups. It is intended for compact robotics projects such as rovers, line-following robots, and STEM prototypes.
