TCA9548A i2C multiplexer

In this video I show a nice device that can help us to use multiple i2C circuits with the same i2C address. There are circuits which have fixed i2C addresses, which means that you can only use one of them on a selected i2C bus. If you try to connect several of them, there will be a conflict on the bus and you would not be able to use them. This multiplexer (MUX) resolves this issue and allows you to use 8 devices with the same address at the same time. The way it works is very simple: first we select which channel we want to use by sending a command to the MUX, then we access the i2C device which is connected to the selected channel.
