STEVAL-MKIT02V1 MEMS Sensor Sample Kit STMicroelectronics STEVAL-MKIT02V1 MEMS Sensor Sample Kit contains four sensor adapter boards that can be evaluated in standalone mode. This can be done by connecting an I2C cable (except for the STEVAL-MKI186V1 and the IIS3DHHC where only the SPI connector is present). The STEVAL-MKI109V3 evaluation board, based on the STM32F401VET6 microcontroller, can be used for a more in-depth evaluation. The board can be used as a bridge between the sensor adapter boards and a PC running STMicroelectronics graphical user interface (GUI) or an X-NUCLEO expansion board.
