IKS4A1 sensor axis information ?

[AnselmeC]

Hello,

 

I'm desparately trying to find a diagram that would explain how the different sensors (accelerometers, magnetometer, gyros...) are oriented on the IKS4A1. We can find individual axis information for each sensor on their specific datasheet, but I don't know how they are integrated into the IKS4A1. I could figure that it seems that the lsm6dsv16x is upside down (Z pointing down) but it's harder to figure it out for the magnetometer (LIS2MDLSensor)

.

Also, another thing : it seems that the Quaternion values given by the lsm6dsv16x have their Z and X axis swapped. I think that a yaw rotation (Z axis) of the board gives a roll information on the output quaternion.

Does anyone has any more information ?

 

Thank you for the help.

You mean X-NUCLEO-IKS4A1 ?

This would normally be on the 'CAD Resources' tab of the Product Page:

But it seems there's only schematics - no layouts.
