Hi,
I am debugging my custom board where I soldered an LIS2DW12 accelerometer on it. I forgot to pull the reserved pin ( 7 ) to ground as suggested in the datasheet.
This is how I connected it:
This is how it should be connected:
Is this required, that the accelerometer can work properly? I cant find it on my I2C bus and don't know if it is related to this little mistake or maybe another, most likely soldering issue.
Edit: I2C is pulled up and decoupling capacitors are also there. Just on another section.
Thank you

Hi @CMoeb.1 ,
Yes, as stated in the datasheet, the RES pin has to be tied to GND... you might try to change the Vdd / VddIO level if you can, for example decreasing it to 1.8V (the pin should be less sensitive to lower voltages).
