The absolute orientation sensor BMX055 is a very small, 9-axis sensor, consisting of a triaxial 12bit acceleration sensor, a triaxial 16bit, ±2000°/s gyroscope and a triaxial geomagnetic sensor. The BMX055 allows accurate measurement of angular rate, acceleration and geomagnetic fields in 3 perpendicular axes within one device.
