The ISM330DHCX is a system-in-package featuring a high-performance 3D digital accelerometer and 3D digital gyroscope tailored for Industry 4.0 applications.

The ISM330DHCX is a system-in-package featuring a high-performance 3D digital accelerometer and 3D digital gyroscope tailored for Industry 4.0 applications.

ST’s family of MEMS sensor modules leverages the robust and mature manufacturing processes already used for the production of micromachined accelerometers and gyroscopes.

The various sensing elements are manufactured using specialized micromachining processes, while the IC interfaces are developed using CMOS technology that allows the design of a dedicated circuit which is trimmed to better match the characteristics of the sensing element.

In the ISM330DHCX the sensing elements of the accelerometer and of the gyroscope are implemented on the same silicon die, thus guaranteeing superior stability and robustness.

The ISM330DHCX 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.

All the design aspects and the calibration of the ISM330DHCX have been optimized to reach superior accuracy, stability, extremely low noise and full data synchronization.

An unmatched set of embedded features (Machine Learning Core, programmable FSM, FIFO, sensor hub, event decoding and interrupts) are enablers for implementing smart and complex sensor nodes which deliver high performance at very low power. The ISM330DHCX is available in a 14-lead plastic land grid array (LGA) package.

評(píng)估板STEVAL-MKI210V1K

iNemo inertial module kit based on ISM330DHCX
The STEVAL-MKI210V1 evaluation board has an embedded ISM330DHCX 3D accelerometer and 3D gyroscope sensor, which is connected through flat cable to a simple adapter board (STEVAL-MKIGIBV2) to render it compatible with STEVALMKI109V3.

The sensor is soldered precisely in the center of the board and double-sidedadhesives are provided to allow users to conveniently mount the board on equipmentdestined for vibration analysis. Alternatively, you can mount the board using the holeslocated in each corner of the PCB.

The STEVAL-MKIGIBV2 can be plugged into a standard DIL 24 socket. The kitprovides the complete IIS3DWB pin-out and comes ready-to-use with the requireddecoupling capacitors on the VDD power supply line.

This adapter is supported by the STEVAL-MKI109V3 motherboard with highperformance 32-bit microcontroller functioning as a bridge between the sensor and aPC, on which it is possible to use the downloadable graphical user interface (UnicoGUI), or dedicated software routines for customized applications.
