CJMCU TCA9548A I2C 8 Channel Multiple Extensions Development Board
The CJMCU TCA9548A I2C 8 multi-channel expansion board allows you to communicate with multiple I2C devices that share the same address. This simplifies the interface between them and the microcontroller. You can connect up to 8 identical I2C devices to one microcontroller using this multiplexer. The multiplexer acts as a gatekeeper, directing the commands to the chosen set of I2C pins according to your command.
The TCA9548A I2C 8 Channel Multiple extensions development board has its own I2C address. You can send it a command to select which I2C multiplexed output you want to use, and then you can access the board you want.
