Accelerometer and gyroscope: ISM330DHCX
The
is a system-in-package featuring a high-performance 3-axis digital accelerometer and 3-axis
digital gyroscope tailored for Industry 4.0 applications. The sensing elements of the accelerometer and of the
gyroscope are implemented on the same silicon die, thus guaranteeing superior stability and robustness.
The
has a full-scale acceleration range of ±2/±4/±8/±16 g and a wide angular rate range of
±125/±250/±500/±1000/±2000/±4000 dps that enable its usage in a broad range of applications.
An unmatched set of embedded features (machine learning core, programmable FSM, FIFO, sensor hub, event
decoding, and interrupts) enable the implementation of smart and complex sensor nodes, which deliver a high
performance at very low power.

Package
14-LGA
Operating voltage
1.71 V to 3.6 V
All the design aspects and the calibration of the
have been optimized to reach superior accuracy,
stability, extremely low noise, and full data synchronization.
The
has an I²C sensor hub, which allows it to behave as the I²C master for other slave devices
connected via an I²C auxiliary bus. Various configurations are possible for different I²C bus connections with or
without the
