I have several lsm303agr that with the accelerometer and the magnetometer in power-down mode consume between 40uA and 20uA while others consume about 2uA as indicated on the datasheet.Even if they have this higher consumption, they perform the self t...

I'm using an LSM303AGR to create a compass using the MotionEC library for calculating quaternions.Since the ODR of the magnetometer inside the LSM303AGR is 20Hz while the ODR of the accelerometer is 25Hz with which frequency and with which data is it...
