    BMI270 Gyro Drift

    I would like to quantify BMI270 Gyro drift i.e  6.25 deg/sec. I looked at the data sheet but It was mentioning some drift and normalization error in which I dont understand. Can someone please help me out ? What is the gyro drift of BMI270?

    Re: BMI270 Gyro Drift

    Hello baray98,

    The following are parameters related to gyro drift, please refer them.

    The chip has an offset by default. When you weld it to the board, the offset will change with the stress. Usually, Let the gyro stand still to calibrate the offset.

    After soldering, using built-in BMI270 re-trimm can reduce effects of solder drift below 1% and close to initial condition.
