Description
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.
