We're considering using the BMI088 or BMI270 for the measurement of the roll and pitch of a device using a Kalman filter to combine the gyroscope and accelerometer. Our main concern is long-term stability. Current consumption is not important.
So far I've read on this forum that the closed-loop gyro of the BMI088 has better long term bias stability. However, the BMI270 has a self-calibrating gyroscope. Which one would be recommended for our application?
