STEVAL-MKI062V1 iNEMO™: inertial module demonstration board based on MEMS and STM32

The STEVAL-MKI062V1 (iNEMO™) is a unique platform designed to demonstrate the performance of ST’s most advanced inertial, temperature and pressure sensors. It provides a complete set of inertial measurements from an accelerometer, magnetometer and gyroscopes, as well as data from pressure and temperature sensors to measure environmental conditions.

This 10-DOF (degrees of freedom) inertial system represents a complete hardware platform for a variety of applications including virtual reality, augmented reality, platform stabilization, human machine interfaces and robotics.

To aid in user development and analysis, the STEVAL-MKI062V1 demonstration kit includes a PC GUI for sensor output display and a firmware library to facilitate the use of the demonstration board features.

A complete set of communication interfaces (USB, wireless, COM), small 4.5 x 5 cm size, and several power supply options make iNEMO a flexible, open evaluation platform.
