STEVAL-MKI109V2
eMotion: ST MEMS adapters motherboard based on the
STM32F103RE compatible with all ST MEMS adapters
Features
■ Compatible with all available ST MEMS
ad
apter boards
■ Controlled by the STM32F103RET6 high-
performance ARM Cortex
™
-M3 microcontroller
■ Includes a DIL24 socket for easy MEMS
ad
apter connection
■ 3 V on-board linear voltage regulator
■ DFU compatible for USB microprocessor
firmware update
■ USB 2.0 full-speed compliant
■ Debugging connector for SWD/JTAG
■ RoHS compliant
Description
The STEVAL-MKI109V2 is a motherboard
designed to provide users with a complete, ready-
to-use platform for the evaluation of
STMicroelectronics’ MEMS products.
The board features a DIL24 socket to mount all
available adapters for both digital and analog
output MEMS devices.
The motherboard includes a high-performance
32-bit microcontroller, which functions as a bridge
between the sensor and a PC, on which it is
possible to use the downloadable graphical user
interface (GUI), or dedicated software routines for
customized applications.
