Pololu MinIMU-9 v6 Gyro, Accelerometer, and Compass (LSM6DSO and LIS3MDL Carrier)

The MinIMU-9 v6 is an inertial measurement unit (IMU) that packs an LSM6DSO 3-axis gyro and 3-axis accelerometer and an LIS3MDL 3-axis magnetometer onto a tiny 0.8? × 0.5? board. An I²C interface accesses nine independent rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s absolute orientation. The MinIMU-9 v6 board includes a voltage regulator and a level-shifting circuit that allow operation from 2.5 to 5.5 V, and the 0.1? pin spacing makes it easy to use with standard solderless breadboards and 0.1? perfboards.

Compared to the previous MinIMU-9 v5, the v6 version replaces the LSM6DS33 accelerometer/gyro MEMS sensor with the newer LSM6DSO, which offers various improvements like lower noise and a higher maximum output data rate for the gyro. The MinIMU-9 v6 should be able to serve as a drop-in replacement for the MinIMU-9 v5 in many applications; in other cases, software changes might be required.

The MinIMU-9 v6 is also pin-compatible with the AltIMU-10 v6, which offers the same functionality augmented by a digital barometer that can be used to obtain pressure and altitude measurements. The AltIMU includes a second mounting hole and is 0.2? longer than the MinIMU. Any code written for the MinIMU-9 v6 should also work with the AltIMU-10 v6.
