STEVAL-MKI109V3
Professional MEMS tool: ST MEMS adapters motherboard
based on the STM32F401VET6 compatible ST MEMS adapters
Data brief
Features
Compatible with all available ST MEMS
adapter boards
Controlled by the STM32F401VET6 high-
performance ARM Cortex™ - M4
microcontroller
Includes a DIL24 socket for easy MEMS
adapter connection
Adjustable MEMS DIL24 power supply
DFU-compatible for USB microprocessor
firmware update
USB 2.0 full-speed compliant
Debugging connector for SWD/JTAG
RoHS compliant
Description
The STEVAL-MKI109V3 motherboard provides
users with a complete, ready-to-use platform for
the evaluation of STMicroelectronics MEMS
products. It includes a high-performance 32-bit
microcontroller which functions as a bridge
between the sensors and a PC, on which you can
download and run the graphical user interface
(GUI) or dedicated software routines for
customized applications.
The board features a DIL24 socket to mount all
available adapters for both digital and analog
output MEMS devices.
