How to Get Started Quickly with STMicroelectronics’ X-NUCLEO-IKS4A1 Expansion Board
I. Hardware Preparation
Required Components
- X-NUCLEO-IKS4A1 expansion board (including main circuit board X-NUCLEO-IQS4A1 and detachable Qvar electrode board STEVAL-MKE001A).
- Compatible STM32 Nucleo development boards (e.g., NUCLEO-F401RE, NUCLEO-L152RE, NUCLEO-U575ZI-Q, NUCLEO-L073RZ).
- USB Type-A to Micro-B cable (for connecting the development board to a PC).
- Computer (Windows 7/8/10).
- Optional components: 12-pin industrial cable (for connecting IR sensors, sold separately).
Hardware Connection
-
Install the Expansion Board:
Directly stack the X-NUCLEO-IKS4A1 on top of the STM32 Nucleo development board, aligning and connecting via the Arduino UNO R3 interface or ST Morpho interface. -
Jumper Configuration (Critical Step):
- Default Mode: All sensors are directly controlled by the STM32, and Qvar electrodes are disabled.
- Connect jumpers J4 and J5 to the first row of pins (1-2 and 11-12, corresponding to the standard I²C bus).
- Enable Qvar Electrodes:
- Connect the last row of pins on J4 and J5 (e.g., 3-4 on J4 and 3-4 on J5) to use LSM6DSO16IS as the Qvar controller.
- Connect Sensors via I2C (using LSM6DSO16IS/LSM6DSV16X as the sensor hub):
II. Software Preparation
Required Tools
- STM32CubeIDE: For code development, compilation, and downloading (download from the official website).
- ST-LINK Driver (STSW-LINK009): Ensures the PC recognizes the development board (download from the official website).
- X-CUBE-MEMS1 Software Package: Includes sensor drivers, sample code, and middleware (download from the official website).
III. Rapid Prototype Development
Compile the code and upload it to the Nucleo development board to test functions (e.g., sensor data acquisition, motor control, wireless transmission), and verify the design.
- One-Stop Development: Integrate the hardware expansion board (Nucleo/X-Nucleo) with modular software (STM32Cube toolchain) to cover the entire process from prototype design to final product, supporting rapid iteration and function expansion.
- Modular Architecture: Covers core embedded system functions through seven modules: Sense, Connect, Human-Machine Interaction (HMI), Move, Power Management (Power), Process, Software, encompassing data collection, transmission, access, execution, power management, processing, and software support.
