    Hi @Junger​ , are you referring to the different footprint pictures on the LIS2MDL documentation? Please consider that LIS2MDL datasheet and adapter have a coherent pinout, and that the footprint reflects a standard LGA-12 package...

    schematic is right but the gerber file is not for LIS2MDL, I found this issue after my PCB back which use the gerber file .

    one simple way to check : PIN3 in the PCB layout had been connect to GND

    the picture is not the same like the EVAL board of MKI181V1

    it is like this

    Hi @Junger​ , I was focusing on the device footprint and not on the signal routing. I now understand what you do mean. The chip is also soldered rotated with respect to the pin1 of the gerber files on the STEVAL-MKI181V1. The fact is that usually this is an ST internal matter since the STEVAL boards are sold whit chips already mounted on them... But I will report this issue internally. Regards
