UM7 Orientation Sensor

Pololu item #: 2741

This product has been discontinued.

This product has been replaced by an equivalent version from Redshift Labs, which has taken over manufacturing and support of the UM7 from the original manufacturer, CH Robotics.

The UM7 orientation sensor from CH Robotics 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.
