Description
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 three-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.
