Dear support team

Is it save to stack up one IO Pi board and one I2C Switch board on a single Raspberry Pi? I am asking because (if not mistaken) the pull-up resistor on the RspberryPi side would be reduced from 10k to 5k.

Hello Marko

It is safe to stack the IO Pi and I2C Switch on a single Raspberry Pi.
