The AltIMU-10 v6 is an inertial measurement unit (IMU) and altimeter that features the same LSM6DSO gyro and accelerometer and LIS3MDL magnetometer as the MinIMU-9 v6, and adds an LPS22DF digital barometer. An I²C interface accesses ten independent pressure, rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s altitude and absolute orientation. The board operates from 2.5 to 5.5 V and has a 0.1″ pin spacing.

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.

This module is a carrier/breakout board for the ST LIS3MDL three-axis magnetometer. The sensor provides magnetic field strength measurements with a configurable range of ±4 gauss to ±16 gauss that can be read through a digital I²C or SPI interface.

The UM7-LT orientation sensor from Redshift Labs is an Attitude and Heading Reference System (AHRS) that contains a three-axis accelerometer, rate gyro, and magnetometer. It combines this data using an Extended Kalman Filter to produce attitude and heading estimates. This LT version of the UM7 does not have an enclosure.

The Pololu MinIMU-9 v5 is an inertial measurement unit (IMU) that packs an LSM6DS33 3-axis gyro and 3-axis accelerometer and an LIS3MDL 3-axis magnetometer onto a tiny 0.8″ × 0.5″ board.
