Digitalisolator of signal I2Cffrom series Gravity. It protects the sensors fromelectrical interferencescausing a read error through theisolation of I2C signaland providingisolated powerto the sensor. Interferences of this type can occur, for example, in the case of using several sensors of the purity of water or the pump where the medium is a conductive fluid.The set includes 2 4-pin goldpin connector and 2 wires suitable forGravity DFRobot IO Expansion Shieldand modules from series Gravity. In our offer, we also have ananalog isolator.

  1. The module must be powered with 5 V
  2. Module, during operation, consumes a lot of current up to 150 mA, it is better to use an external power source
  3. The sensor and the microcontroller (e.g. Arduino) are isolated, do not connect them together
  4. The module can become hot during operation


The system has four pins on special connectors, to which the wires are in the kit.
