Product details

Overview

X-NUCLEO-IKS4A1 from STMicroelectronics is a motion and environmental sensor evaluation board kit comprising the main board X-NUCLEO-IQS4A1 and detachable Qvar electrode board STEVAL-MKE001A. It integrates six MEMS sensors-including LSM6DSV16X (6-axis IMU with AI, sensor fusion, and SPI aux interface), LIS2DUXS12 (ultra-low-power 3-axis accelerometer with Qvar and AI), LPS22DF (260–1260 hPa barometer), SHT40AD1B (±1.5% RH / ±0.1 °C temp/humidity), LIS2MDL (±50 gauss magnetometer), and STTS22H (±0.5 °C temp sensor)-and supports I²C, MIPI I3C®, and SPI communication for multi-sensor synchronization and camera EIS/OIS development.

For engineers reviewing the X-NUCLEO-IKS4A1 datasheet, X-NUCLEO-IKS4A1 pinout, X-NUCLEO-IKS4A1 application, or X-NUCLEO-IKS4A1 equivalent, key selection considerations include Arduino UNO R3 and STM32 Nucleo compatibility, dual I²C sensor hub capability (LSM6DSO16IS & LSM6DSV16X), Qvar touch/swipe electrode routing, DIL24 socket for MEMS expansion, and IR sensor interface for presence detection.

Technical Context

The board implements a hierarchical sensor architecture: LSM6DSV16X serves as primary IMU with embedded sensor fusion and auxiliary SPI for camera stabilization; LIS2DUXS12 provides ultra-low-power motion sensing with Qvar-based gesture detection and anti-aliasing filtering; LPS22DF and SHT40AD1B deliver high-precision environmental monitoring with independent I²C addresses (0xB8h and 0x44h). All sensors share coordinated interrupt routing via dedicated INT pins mapped to STM32 GPIOs.

Communication is segmented across three I²C buses-STM_I2C (main MCU interface), SENS_I2C (environmental sensors), and HUB2_I2C (IMU hub)-with level-shifting via NXS0108BQX translators. The DIL24 socket enables hot-swappable MEMS adapters, while MIPI I3C® support on LIS2DUXS12, LSM6DSV16X, and LPS22DF allows scalable multi-node timing and command arbitration without bus contention.

FAQ

What software tools support X-NUCLEO-IKS4A1 firmware development?

X-NUCLEO-IKS4A1 is natively supported by STM32CubeMX for pin configuration and middleware setup, X-CUBE-MEMS1 for sensor driver integration, and MEMS-Studio for no-code algorithm design and embedded AI model deployment directly onto LSM6DSV16X and LIS2DUXS12 ISPU cores.

Can X-NUCLEO-IKS4A1 operate standalone without an STM32 Nucleo board?

No - X-NUCLEO-IKS4A1 is an expansion board requiring connection to an STM32 Nucleo development board via Arduino UNO R3 or Morpho headers. It lacks onboard MCU, power regulation for host operation, or USB interface; all sensor data acquisition and processing depend on the host Nucleo MCU.

How are interrupt signals from multiple sensors managed on this board?

Each sensor's interrupt outputs (INT1/INT2/DRDY) are individually routed to discrete STM32 GPIO pins via configurable jumpers (JP1–JP7) and signal buffers. No shared interrupt lines are used; this enables precise source identification and concurrent real-time handling of motion, environmental, and Qvar events without masking or polling overhead.

Does the board support simultaneous use of both LSM6DSV16X and LSM6DSO16IS sensor hubs?

Yes - the board provides two independent I²C sensor hub channels (HUB1_I2C and HUB2_I2C), each with dedicated SCL/SDA lines, level shifters, and interrupt routing. Both LSM6DSV16X and LSM6DSO16IS can operate concurrently with separate configurations, enabling hybrid motion tracking (e.g., high-dynamic-range + low-power always-on modes) and cross-validation.
