Description
Have you ever wanted to connect more than one I2C device to a single controller and couldn't because they have identical I2C addresses? With the I2C Multiplexer (I2C MUX) you can use up to 8 devices with the same address on the same bus! This allows you to reach several sensors at once without having to use several microcontrollers at the same time. Best of all, the TCA9548A, the IC on which this breakout is based, has three adjustable pins for the I2C address, which means a total of 8 possible addresses. So you can reach 64 devices with the same address on the same bus. For example, it is possible to connect 64 BME680 sensors that are read by only one microcontroller.
