... 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 ...
