STMicroelectronics IIS2ICLX
High-accuracy, high-resolution, low-power, 2-axis digital inclinometer with embedded machine learning core
The IIS2ICLX is a high-accuracy (ultra-low noise, high stability and repeatability) and low-power two-axis linear accelerometer with digital output. CES Innovation Award 2021 for MEMS Inclinometer with machine-learning core (IIS2ICLX)The IIS2ICLX has a selectable full scale of ±0.5/±1/±2/±3 g and is capable of providing the measured accelerations to the application over an I²C or SPI digital interface.
Its high accuracy, stability over temperature and repeatability make IIS2ICLX particularly suitable for inclination measurement applications (inclinometers).

Available tools
STEVAL-MKI209V1K:
MEMS inclinometer kit based on IIS2ICLX
The STEVAL-MKI209V1K evaluation board has an embedded IIS2ICLX inclinometer sensor, which is connected through flat cable to a simple adapter board (STEVAL-MKIGIBV2) to render it compatible with STEVAL-MKI109V3. The sensor is soldered precisely in the center of the board and double-sided adhesives are provided to allow users to conveniently mount the board on equipment destined for vibration analysis. Alternatively, you can mount the board using the holes located in each corner of the PCB.
