CJMCU TCA9548A – I2C 8 Channel Multiple Extension Development Board
CJMCU TCA9548A I2C 8 Channel Multiple Extensions Development Board. You just found the perfect I2C sensor, and you want to wire up two, three, or more of them to your Arduino. When you realize “Oh no, this chip has a fixed I2C address, and from what I know about I2C; you cannot have two devices with the same address on the same SDA/SCL pins”. Are you out of luck? You would be if you don’t have this cool CJMCU TCA9548A I2C 8 Channel Multiple extensions development board. The CJMCU TCA9548A I2C 8 Channel Multiple extensions development board is interesting in that it has an I2C address (0x70 by default) – and 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. This product is known as PCA9548A, PCA9548A 8-channel I2C-bus switch with reset, PCA9548A Development Board, TCA9548A, TCA9548A I2C 8 Channel Multiple Extensions Development Board, CJMCU TCA9548A I2C 8 Channel Multiple Extensions Development Board.
