The X-NUCLEO-IKS4A1 sensor expansion board for STM32 Nucleo boards includes a variety of sensors. These include an IMU with an embedded processing unit, an IMU with an embedded sensor fusion block, a high-precision pressure sensor, and a temperature and humidity sensor. It also features a QR electrode board for touch and swipe detection, a socket for an infrared sensor, and a DL 24 socket for external sensors.
Here's a more detailed breakdown:

IMUs: The board includes both an LSM6DSO16IS (ultra-low power, high-performance 3-axis IMU with embedded processing) and an LSM6DSV16X (6-axis IMU with embedded sensor fusion, AI, and Qvar).
Pressure Sensor: The LPS22DF is a low-power, high-precision MEMS nano pressure sensor.
Temperature and Humidity Sensor: The SHT40-AD1B is a digital humidity and temperature sensor.
Magnetometer: The LIS2MDL is an ultra-low-power 3-axis magnetometer.
Accelerometer: The LIS2DUXS12 is an ultra-low-power 3-axis smart accelerometer.
Qvar Electrode Board: Used for touch and swipe detection.
Infrared Sensor Socket: Provides a connection point for an infrared sensor.
DL 24 Socket: Allows for the connection of external sensors.
