Gravity Digital I2C Signal Isolator Optocoupler

The Gravity: Digital I2C Signal Isolator can isolate the digital I2C signal and power the isolated sensor module, thereby preventing mutual interference between the sensor modules. It can be used for multiparameter water quality detection systems to prevent interferences from water quality sensors. The product is plug-and-play, does not require soldering and no need to alter the sensor module’s code in the control board. Especially designed for DFRobot I2C port sensors or modules, it can provide electrical isolation to ensure stable operation of the sensor modules. 


  • Integrated 5V 0.75W isolation power chip, no additional power supply needed, simple and convenient
  • Almost compatible with all DFRobot I2C port sensors or modules, plug and play, no soldering required
