Offers an ultra-cool PCA9546 1-to-4 I2C multiplexer
Comes with only the assembled PCB
Communication interface: I2C
Note: No cables or sensors are included
The Adafruit PCA9546 4-Channel I2C Multiplexer TCA9546A Compatible comes with only the assembled PCB, no cables or sensors included. 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 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 8x4 = 32 of the same-I2C-addressed-part.
