TCA9548A 1-to-8 I2C 8 -way multi-channel expansion board IIC module development board
You just found the perfect I2C sensor, them to your when you realize "Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you can not have Two devices with the same same on the same SDA / SCL pins! "Are you out of luck? You would be, if you did not have this ultra-cool CJMCU-9548 1-to-8 I2C multiplexer!
Finally, a way to get up to 8 same-address I2C devices hooked up to one microcontroller - this multiplexer acts as a 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 you simply write a single byte with the desired multiplexed output number to that port, and bam - any future I2C packets Will 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.
we put this nice chip on a breakout for you so you can use it on a breadboard with capacitor, and pullups and pulldowns to make usage a snap. Some header is required and once soldered in you can plug it into a Solder the chip is very easy to use it with any logic level.
