Description
The TCA9548A I2C Multiplexer 8-Way Expansion Board is the most convenient way to communicate with max 8 same-address I2C devices in the same I2C bus. 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. you could have 8 of these multiplexers on each of 0x70-0x77 addresses in order to control 64 of the same-I2C-addressed-part.
