However, it will not work if you want to connect multiple I2C\ndevices with the same address. I2C multiplexer allows you to communicate with\nup to 8 I2C devices with the same I2C bus. The multiplexer communicates with a\nmicrocontroller using the I2C communication protocol. Then, you can select\nwhich I2C bus on the multiplexer you want to address. To address a specific\nport, you just need to send a single byte to the multiplexer with the desired\noutput port number. Package includes: 5 x TCA9548A I2C IIC multiplexer\nbreakout board. \"\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eInterface: There are 8 I2C interfaces on 1 expander, equipped with 8 bi-directional switches that can be controlled via the I2C bus.
