Description

Module with multiplexer that allows you to connect 8 different digital I2C 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 from 3 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 to 64 devices through a single I2C interface of minicomputer. The kit also includes a cable suitable for Gravity DFRobot IO Expansion Shield and a 4-pin goldpin connector.
