description

You just found the perfect I2C sensor, you want to connect two or three or more of them to your , when you realize that "Hey, this chip has a fixed I2C address, from what I know I2C, you can't have two devices with the same address on the same SDA / SCL pin! Have you lost your luck? You would be if you don't have this cool TCA9548A 1 to 8 I2C multiplexer!

Finally, a method can connect up to eight I2C devices of the same address to a microcontroller - this multiplexer acts as a gatekeeper, using your commands to route commands to a selected set of I2C pins. .

Using it is quite simple: the multiplexer itself is at I2C address 0x70 (but can be adjusted from 0x70 to 0x77), you just write a byte with the desired multiplexed output number to that port, bam - any Future I2C packets will be sent to this port. In theory, to control 64 identical I2C addressing sections, you can use 8 of these multiplexers at each of the 0x70-0x77 addresses.

Like all breakthroughs, we put this good chip in the break of you, so you can use it in capacitors, pull up and pull down the breadboard to make use of it. Some plugs are required and once soldered you can insert them into a solderless breadboard. The chip itself is 3V and 5V compatible, so you can use it with any logic level.
