Hi,
actually I am struggeling around by reading magentometer data using LISM3MDL with this board .
When checking for I2C addresses connected to arduino sometimes address is 0x1C but partly it changes to 0x1E.
I guess trigger for that problem is, that SDO/SA1 is neither connected to ground nor V+.
Does anyone know which pin on breakoutboard belongs to SDO/SA1 of magnetomter?
I could not find any schematics, just this datasheet which doesn't show the connections between magnetometer and breakoutboard. Pindescription isn't helpful too...
According to the Adafruit product page, "You can change the I2C addresses on the back using the solder jumpers, to have two of these sensor boards on one bus."
Contact Adafruit technical support if you can't find the details on those jumpers.

"You can change the I2C addresses on the back using the solder jumpers, to have two of these sensor boards on one bus."
I thought this statement is related to the product "Adafruit Feather STM32F405 Express".
@jremington you are right, there are to solder jumpers on the back.
They are described by ADM and ADAG.
Are both jumpers for initializing I2C address?
I just looked at the product page for that sensor, and know nothing else about it.
