What hardware does STMicroelectronics’ X-NUCLEO-IKS4A1 expansion board have?

The X-NUCLEO-IKS4A1 is an STM32 Nucleo expansion board designed to control and develop custom applications with the latest STMicroelectronics (ST) MEMS inertial sensors and environmental sensors. The board is equipped with:

Sensor Modules:

  • LIS2DUXS12 : 3-axis accelerometer with integrated Qvar (capacitive touch/slide detection), AI capabilities, and anti-aliasing filtering.
  • LSM6DSO16IS : 3-axis accelerometer + 3-axis gyroscope with ISPU (Intelligent Sensor Processing Unit) for preprocessing sensor data.
  • LSM6DSV16X : 6-axis IMU (Inertial Measurement Unit) with AI, Qvar functionality, and embedded sensor fusion algorithms (e.g., attitude calculation).
  • LIS2MDL : 3-axis magnetometer for magnetic field detection (e.g., electronic compass applications).
  • LPS22DF : High-precision nanobarometer for air pressure measurement.
  • STTS22H : Temperature sensor for monitoring ambient temperature.
  • SHT40AD1B : Humidity sensor (from Sensirion) for measuring ambient humidity.
