Hi,

what ist the power comsumption of the Mux board.

And do the I2C line have to be 3.3 v so that i would need level conversion from arduino pin or could it be also apron. 5 V (arduinio without level conversion)?

thx

Power consumption will be <45mA @ 192kHz.

There is no I2C interface. You will need to use GPIOs for the two control pins. They are limited to 3.3V, but you can simply build a voltage divider with a pair of resistors for each pin, which will also act as a pull-down, so you only need to switch high.
