## Description

The Gravity:TT Motor Encoders Kit provides rotation tracking for TT motors, giving you accurate angular displacement data using a non-contact sensing method. Ideal for robotics projects where you need to measure wheel rotation and distance travelled. The kit uses the Gravity interface for plug-and-play connectivity with Arduino or Raspberry Pi expansion shields. It pairs perfectly with DFRobot's micro DC geared motors (FIT0016). Specifications Voltage – 5 V Current – <20 mA Resolution – 20 PPR (pulses per revolution) Weight – 20 g Ideal For TT motor-driven robots and rovers Odometry and distance measurement Speed control and PID feedback loops Package Contents 2× M3×5 screws 4× M3×50 screws 4× Rubber rings 4× Washers 4× Plastic covers 2× Grating discs 2× Digital cables Resources Arduino Sample Code Product Wiki
