Module withmultiplexerthat allows you to connect8 differentdigitalI2C buses to one interface, for each, there are separate pins SDA (bus of data line) and SCL (clock line of the bus). The device operates with a supply voltage from3 V to 5 V, the output I2C bus has the ability to change the default address,0x70 to 0x77. Theoretically, it is possible to connect up to 8 multiplexers that allows you to control up to64 devices through a single I2C interfaceof minicomputer.The kit also includes a cable suitable forGravity DFRobot IO Expansion Shieldand a 4-pin goldpin connector.
The system has four pins on a special connector, to which the cable is included in the package.
