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 Pololu AltIMU-10 v6 is a compact (1.0? × 0.5?) board that combines ST’s LSM6DSO 3-axis gyroscope and 3-axis accelerometer, LIS3MDL 3-axis magnetometer, and LPS22DF digital barometer to form an inertial measurement unit (IMU) and altimeter; we therefore recommend careful reading of the LSM6DSO datasheet (3MB pdf), LIS3MDL datasheet (2MB pdf), and LPS22DF datasheet (1MB pdf) before using this product. These sensors are great ICs, but their small packages make them difficult for the typical student or hobbyist to use. They also operate at voltages below 3.6 V, which can make interfacing difficult for microcontrollers operating at 5 V. The AltIMU-10 addresses these issues by incorporating additional electronics, including a voltage regulator and a level-shifting circuit, while keeping the overall size as compact as possible. The board ships fully populated with its SMD components, including the LSM6DSO, LIS3MDL, and LPS22DF, as shown in the product picture.

Compared to the previous AltIMU-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. It also replaces the LPS25HB pressure sensor with the LPS22DF, which features improved accuracy and reduced noise in the output and a much higher maximum output rate. The AltIMU-9 v6 is pin-compatible with the AltIMU-9 v5 and should be able to serve as a replacement with some software changes.

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

Included Components

A 1×6 strip of 0.1? header pins and a 1×5 strip of 0.1? right-angle header pins are included, as shown in the picture below. You can solder the header strip of your choice to the board for use with custom cables or solderless breadboards or solder wires directly to the board itself for more compact installations. The board features two mounting holes that work with #2 or M2 screws (not included).
