The Pololu AltIMU-10 V6 3-Axis Gyro, Accelerometer, Compass & Altimeter is an advanced inertial measurement unit and altimeter that integrates a suite of sensors to provide comprehensive orientation and altitude data. The unit features a high-performance LSM6DSO gyro and accelerometer, an LIS3MDL magnetometer, and an LPS22DF digital barometer. These components work in concert to deliver ten independent measurements through an I²C interface, enabling the calculation of the sensor's altitude and absolute orientation.

This compact module is designed to facilitate ease of use for a variety of applications, including those by students and hobbyists. It incorporates additional electronics such as a voltage regulator and a level-shifting circuit to accommodate microcontrollers operating at different voltage levels while maintaining a small form factor. The AltIMU-10 V6 is fully populated with surface-mounted devices, ensuring readiness for immediate deployment.

The latest iteration of the AltIMU series, the V6 version, offers enhancements over its predecessors, including improved noise performance and a higher maximum output data rate for the gyro, as well as increased accuracy and a higher maximum output rate for the barometer. The unit is pin-compatible with previous versions, allowing for straightforward replacement with minimal software modifications.

The AltIMU-10 V6 is also compatible with the MinIMU-9 V6, sharing the same functionality with the addition of a digital barometer for pressure and altitude measurements. The device is designed to be user-friendly, with configurable options for the gyro, accelerometer, magnetometer, and barometer, including selectable sensitivities and output data rates. The sensors are accessible through a shared I²C interface, and a slave address configuration pin is provided to facilitate the connection of multiple AltIMUs on the same I²C bus.

The module's carrier board includes a low-dropout linear voltage regulator, enabling power from a single 2.5 V to 5 V supply, and a level-shifting circuit for I²C communication compatibility with 5 V systems. The 0.1″ pin spacing allows for easy interfacing with standard solderless breadboards and perfboards.

The AltIMU-10 V6 is a sophisticated device that requires careful handling and understanding of the datasheets provided for the LSM6DSO, LIS3MDL, and LPS22DF. It is recommended to thoroughly review these documents before use. Additionally, the sensors operate at voltages below 3.6 V, which should be considered when interfacing with 5 V microcontrollers.
