INEMO-M1
iNEMO system-on-board
Data brief
Cortex™ M3 32-bit MCU. This 9-DoF inertial
system represents a fully integrated solution that
can be used in numerous applications such as
virtual reality, augmented reality, image

C
stabilization, human machine interfaces, robotics
and inertial body tracking. A complete set of
communication interfaces in a very small size
form factor (13x13x2 mm) make the INEMO-M1
system-on-board a flexible solution for effortless
orientation estimation in embedded applications.
Applications
■ Gaming and virtual reality
■ Robotics and inertial body tracking
■ Personal navigation devices and location
based services
■ Fitness and healthcare
Description
The INEMO-M1 is the smallest 9-axis system-onboard (SoB) of the iNEMO module family. It
integrates multiple ST sensors with a powerful
computational core: a 6-axis geomagnetic
module, a 3-axis gyroscope and an ARM
