STEVAL-MKI062V2, iNEMO™ (iNErtial MOdule) demonstration
board based on MEMS devices and STM32F103RE
Introduction
The STEVAL-MKI062V2 is the second generation of the iNEMO™ module family. It
combines accelerometers, gyroscopes and magnetometers with pressure and temperature
sensors to provide 3-axis sensing of linear, angular and magnetic motion, complemented
with temperature and barometer/altitude readings, representing the new ST 10 degrees of
freedom (DOF) platform.
The STEVAL-MKI062V2 represents a further step in miniaturization in the iNEMO family. It
integrates five STMicroelectronics sensors: a 2-axis roll-and-pitch gyroscope, a 1-axis yaw
gyroscope, a 6-axis geomagnetic module, a pressure sensor, and a temperature sensor.
This 10-DOF inertial system represents a complete hardware platform that can be used in
many applications, such as gaming, location-based service, human machine interfaces, and
robotics.
A complete set of communication interfaces with various power supply options in a small
size form factor (4 x 4 cm) make the iNEMO a flexible and open demonstration platform.
