CJMCU 9548 TCA9548A 1-to-8 I2C 8 way multi channel Multiplexer

You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize Uh Oh, this chip has a fixed I2C address, and from what I know about I2C, you cannot have two devices with the same address on the same SDA/SCL pins Are! \You out of luck You would be if? You didn't have this ultra-cool CJMCU-9548I2C multiplexer 1-to-8! Finally, a way to get up to I2C devices hooked up 8 same-address to one microcontroller multiplexer acts as a - this gatekeeper, shuttling the commands to the selected set of I2C pins with your command. Using it is fairly straight-forward: the multiplexer itself is on I2C address 0x70 (but can be adjusted from 0x70 to 0x77 and simply write a) you single byte with the desired multiplexed output number to that port and bam future I2C packets will - any get sent to that port. In theory, you could have 8 of these multiplexers on each of 0x70-0x77 addresses in order to control 64 of the same-I2C-addressed-part. Like all Adafruit breakouts, we put this nice chip on a breakout for you so you can use it on a breadboard with capacitors, and pullups and pulldowns to make usage a snap. Some header is required and once soldered in you can plug it into a solderless-breadboard. The chip itself is 3V and 5V compliant so you can use it with any logic level. You can wire up two or more chip that have a fixed I2C address on the same SDA / SCL pins using 1-to-8 I2C multiplexer.
