AltIMU-10 v3 Gyro, Accelerometer, Compass, and Altimeter (L3GD20

The Pololu AltIMU-10 v3 is an inertial measurement unit (IMU) and altimeter that features the same L3GD20D gyro and LSM303D accelerometer and magnetometer as the MinIMU-9 v3, and adds an LPS331AP 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.
