iNEMO advanced inertial module: 3D accelerometer, 3D gyroscope and signal processor

The LSM6DB0 is an advanced low-power high-performance smart sensor system available in a plastic 3x3x1 mm LGA (land grid array) package. The module includes a 3-axis accelerometer, 3-axis gyroscope and Cortex-M0 core with Flash, SRAM, dual timers, 2 I2C (master/slave), 1 SPI (master/slave) and 1 UART (transmitter/receiver).

The LSM6DB0 has a full-scale acceleration range of ±2/±4/±8 g and an angular rate range of ±245/±500/±2000 dps. The LSM6DB0 has two operating modes in that the accelerometer and gyroscope sensors can be either activated at the same ODR or the accelerometer can be enabled while the gyroscope is in power-down.

The module collects inputs from the accelerometer, gyroscope, compass and several other sensors and elaborates/fuses together 9 or 10 axes (iNemo Engine software) which are provided to the main application processor. For example, quaternions achieve the best compromise in terms of power saving for the overall system. The LSM6DB0 is fully compliant with the Android Kitkat OS.
