The Pololu AltIMU-10 is an IMU (Inertial Measurement Unit) and altimeter that features an L3GD20 3-axis gyro, an LSM303DLHC 3-axis accelerometer and a 3-axis magnetometer as well as 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.
