DFRobot Gravity: 360 Degree Rotary Encoder Module

This looks like a potentiometer, but it’s an encoder switch.

It is a cascadable 360 ° rotary encoder switch with 20 pulses per revolution, and each pulse corresponds to a detent. There are LED lights set for each detent to allow users visually check the real-time status of the encoder.

For ease of use, the module is designed with I2C data output and configurable accuracy within 1~51 for every detent (set in the program). For instance, when it is set to 1, turn on one LED light by rotating 2.5 revolutions; when set to 51, then one LED light can be switched on by rotating one detent.

In order to apply to more scenarios, the encoder is equipped with a cascade function that enables to control of multiple output devices by occupying only one I2C interface, such as, simultaneously controlling light brightness, color, volume, speed, etc.
