The LSM9DS1 is not the same set of sensors as the LSM9DS0. Here are some of the differences:
- LSM9DS0 accelerometer has ±2/±4/±6/±8/±16 g ranges. The LSM9DS1 has ±2/±4/±8/±16 g (no ±6 g range).
- LSM9DS0 magnetometer has ±2/±4/±8/±12 gauss ranges. The LSM9DS1 has ±4/±8/±12/±16 gauss ranges. So the LSM9DS0 has ±2 gauss low range where-as the LSM9DS1 has ±16 gauss high range.
- LSM9DS0 and LSM9DS1 gyros both have the same ±245/±500/±2000 dps ranges.
There are other differences, for example we noticed the LSM9DS1 has slightly worse accuracy. The gyro angular zero-rate (±25 for the LSM9DS0 and ±30 for the LSM9DS1 at the highest sensing range). The accelerometer offset accuracy is ±90 mg for the LSM9DS1 and ±60 mg for the LSM9DS0.
