Hi,

   Could someone tell me what is the reason for having a 1.8V supply for the digital I/O of the accelerometer.One reason Im guessing could be lower power consumption and compatibility with lower voltage peripherals but in this case the MCU on INEMO board is running at 3.3volts.

Regards

Hansen

I believe its because the MAG digital IOs work at max 2.0 volt

But you can use 3.3V to supply for it
