Overview

Discontinued.  Upgrade to the new UM7.  We still have a handful in stock, but we won’t be building more after we run out. Pololu also still has some in stock here: http://www.pololu.com/product/2723.

The UM6 provides orientation measurements using Euler Angles (yaw, pitch, and roll) and quaternions. In addition to orientation, the UM6 reports raw and processed sensor data from the accelerometers, rate gyros, and magnetic sensors. The UM6 also has the capability to interface with external GPS modules to provide position, velocity, course, and speed information.

A variety of tools are available to simplify configuration and testing of the UM6, including a Serial Expansion Board that comes with all the accessories needed to connect the UM6 to your computer. Using the Serial Expansion Board along with the CHR Serial Interface software (available for download), you can change any sensor setting, log and graph data in real-time, and calibrate the magnetic sensors for the best possible accuracy.

Outputs (User-Selectable)
