DFRobot Gravity 360° I2C Rotary Encoder

This is a 360° rotary encoder module with 20 pulses per revolution from DFRobot. The module communicates via I2C and can be configured for an accuracy of 1-51. This means that when set to 1, it will switch after 2.5 revolutions. When set to 51, it will switch after one increment. To enable more applications, the encoder is equipped with a cascading function that allows multiple output devices to be controlled using only one I2C interface.
