The first 9-Axis MEMS IMU from Bosch for Consumer Applications
Combines 3-Axis Gyroscope, 3-Axis Accelerometer and 3-Axis Magnetometer

In the race of motion integration, Bosch Sensortec has released its first 9-Axis IMU for consumer applications. The BMX055 combines a 12-bit 3-Axis accelerometer, a 16bit 3-Axis gyroscope and a wide-range 3-Axis geomagnetic sensor in a 4.5x3.0mm LGA package (the smallest footprint at its introduction).

It is the first 9-Axis MEMS IMU where all the functionalities are developed and manufactured by the same player. The BMX055 integrates the second generation of Bosch geomagnetic sensor where the 3-Axis are integrated on a single die compared to 3 separates dies for the previous generation.
