STEVAL-IFS002V1
STR9 MEMS extension
Introduction
This user manual describes the STEVAL-IFS002V1 STR9 MEMS extension hardware. As
well as the block diagram and schematics of the extension, a bill of materials and assembly
instructions are also included.
The STR9 MEMS extension 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 extension 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.
