The UM6-LT Orientation Sensor is an OEM version of the UM6. Like the UM6, the UM6-LT combines data from rate gyros, accelerometers, and magnetic sensors to produce real-time attitude and heading measurements using either quaternions or Euler Angles.
The expansion boards designed for the UM6 can be used with the UM6-LT, but soldering will be necessary.
The UM6-LT is a pin-compatible replacement for the CHR-6dm, which has been discontinued. While the footprint is compatible with the 6dm, the UM6-LT utilizes the communication protocol of the UM6, not the 6dm.
