TCA9548A 8 Channel I2C Multiplexer Module
TCA9548A I2C Multiplexer
✅The TCA9548A I2C Multiplexer enables you to connect devices with the same I2C address (up to 8 same-address I2C) hooked up to one microcontroller. The multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pins with your command.
✅The multiplexer itself is on I2C address 0x70 (but can be adjusted from 0x70 to 0x77), simply write a single byte with the desired multiplexed output number to that port, any future I2C packets will get sent to that port.
