STEVAL-IFS002V2

STR9 MEMS demonstration board

1 Introduction

This user manual describes the STEVAL-IFS002V2 STR9 MEMS demonstration board 
hardware. As well as the block diagram and schematics of the demonstration board, a bill 
of materials and assembly instructions are also included.

The STR9 MEMS demonstration board provides an STR9 dongle-based application with 
a MEMS sensor. MEMS (micro-electro-mechanical system) exploits the mechanical 
properties of silicon to create movable structures that, in the case of MEMS-based motion 
sensors, are able to sense motion (acceleration or vibration) in distinct directions. 

The demonstration board used here can be assembled with several types of digital MEMS 
sensors as well as analog ones. For data storage, there is assembly space for ST serial 
Flash. The integration of voltage regulators and operational amplifiers is optional and 
depends on the intended chip usage.
