Hi, regarding the STEVAL-MKI208V1K, what is the purpose of the pins CSX, SDX, OSDO and OCS?
In the diagrams of the Data brief available from the web page, it can be seen that those pins actually are not coming from the IIS3DWB pins.
I want to connect the STEVAL-MKI208V1K to a breadboard (not using STEVAL-MKI109V3) and I'm not sure what to do with those pins.
Also, what is the idea or theory behind giving separate supply to VDD and VDD_IO?
Thanks in advance!

The STEVAL-MKI208V1K was developed as a companion daughter board to the mother board STEVAL-MKI109V3, which supports a bunch of other daughter boards requiring the signals in question.
VDD_IO and VDD are separated because the sensor can also be connected to MCUs with a supply voltage other than 3.3V, e.g. 1.8V.
