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.
