Introducing the Industrial MEMS Sensor Sample Kit from STMicroelectronics

STMicroelectronics have launched the STEVAL-MKIT02V1 MEMS sensors’ sample kit for industrial applications which includes 4 different MEMS sensor adapter boards to help designers easily evaluate and speed up time to market. The kit can be used to evaluate the IIS2MDC 3-axis digital output Magnetometer, the IIS2DH 3-axis digital accelerometer, the ISM330DLC iNEMO 6DoF inertial module and the IIS3DHHC 3-axis digital inclinometer.

The evaluation kit contains 4 adaptor boards as follows:

STEVAL-MKI185V1 Adapter board for the IIS2MDC
STEVAL-MKI168V1, Adapter board for the IIS2DH
STEVAL-MKI182V2, Adapter board for the ISM330DLC

STEVAL-MKI182V2 Adapter board for ISM330DLC – iNEMO 6DoF inertial module overview

MKI182V1

The ISM330DLC is a system-in-package featuring a high-performance 3D digital accelerometer and 3D digital gyroscope tailored for Industry 4.0 applications

The STMicroelectronics family of MEMS sensor modules all leverage ST’s 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 ISM330DLC the sensing element of the accelerometer and of the gyro are implemented on the same silicon die, thus guaranteeing superior stability and robustness, the device has a full-scale acceleration range of ±2/±4/±8/±16 g and an angular rate range of ±125/±250/±500/±1000/±2000 dps. Delivering high accuracy and stability with ultra-low power consumption (0.75 mA in high-performance, combo mode) enables, also in the industrial domain, long-lasting battery-operated applications.

The ISM330DLC includes a dedicated configurable signal processing path with low latency, low noise and dedicated filtering specifically intended for control loop stability. Data from this dedicated signal path can be made available through an auxiliary SPI interface, configurable for both the gyroscope and accelerometer. High-performance, high-quality, small size and low power consumption together with high robustness to mechanical shock makes the ISM330DLC the preferred choice of system designers for the creation and manufacturing of versatile and reliable products.

The ISM330DLC is available in a plastic, land grid array (LGA) package.

These MEMS sensors have all been designed specifically with industrial applications in mind and are included in STMicroelectronics 10 years longevity commitment program, which assures continuity and stability of supply for industrial applications requiring long-term product availability.

For a more in-depth evaluation, STMicroelectronics have also produced a motherboard based on the STM32F401VET6 microcontroller which functions as a bridge between the sensor adapter boards and a PC running ST’s graphical user interface (GUI) or X-NUCLEO system board that is the standard ST evaluation tool.
