INEMO-M1 System-On-Board

The INEMO-M1 is the first 9-axis motion sensing system-on-board (SoB) of the iNEMO module family. It integrates multiple MEMS sensors from STMicroelectronics and a powerful computational core: a 6-axis digital e-compass, 3-axis digital gyroscope, and an ARM®Cortex™-M3 32-bit MCU. This 9-DoF inertial system represents a fully-integrated solution that can be used in a broad variety of applications such as robotics, personal navigation, gaming, and wearable sensors for healthcare, sports, and fitness.

A complete set of communication interfaces and motion-sensing capabilities in a very small size form-factor (13 x 13 x 2 mm) and the possibility to embed ST’s sensor fusion software make the INEMO-M1 system-on-board a flexible solution for high-performance, effortless orientation estimation and motion-tracking applications.
