Buy Online Techtonics CJMCU-9548 TCA9548A 1-to-8 I2C 8 Channel IIC Multiple extensions development board from BuyBestBrands.in in Association with Amazon India
The CJMCU TCA9548A I2C 8 Channel Multiple extensions development board is interesting in that it has an I2C address (0x70 by default)
you basically send it a command to tell it which I2C multiplexed output you want to talk to, then you can address the board you want to address.
Note that you if you happen to have I2C devices with I2C address 0x70, you will need to short one of the Addr pins on the TCA9548 breakout to Vin in order to make it not conflict. Given that you can have 0x70 thru 0x77, just find one thats free and youre good to go.
