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 cascade function that enables to control multiple output devices by occupying only one I2C interface, such as, simultaneously controlling light brightness, color, volume, speed, etc.Use Case Diagram (Control RGB LED by three encoders)Features:Pluggable cascade I2C Data output, forward to increase, reverse to decreaseOnboard LED detent indicatorAllow setting 4 different I2C addresses by address switchApplications:Application FieldAutomotive electronicsMultimedia speakerInstruments and ApparatusesSmart homeApplication CaseVolume adjustmentFire regulationSpeed regulationLight adjustmentSpecification:Operating Voltage: 3.3V~5VTotal Rotating Angle: 360°Pulses Per Revolution: 20Interface: two Gravity connectors; I2CCascadable Device Number: 4Rotation Lifespan: 30000±200 CyclesContact Resistance: ≤100mΩInsulation Impedance: 100MΩ aboveOscillation: 10ms pressOperating Temperature: -30~+80Accuracy: 1~51Minimum Settable Value: 1(Light up one LED when rotating 2.5 turns)Maximum Settable Value: 51(Light up one LED when rotating 1 detent)Storage: 0~1023Dimension: 37*37mm/1.46*1.46”Documents:Product wikiProduct Includes:Gravity: Rotary Encoder Module x1Gravity I2C/UART Sensor Connector x1
