The Neblina™ core module is a low-power self-contained AHRS, VRU and IMU with wireless connectivity developed by Motsai. The miniature board features a high-performance patent-pending sensor fusion algorithm that makes it suitable to explore motion analytics in industrial. wearable technology devices in applications such as biomechanical analysis, sports performance analytics, remote physical therapy monitoring, quantified self, health and fitness tracking, among others.

Functions and Benefits

The Neblina module facilitates the evaluation of real-life applications that require 3D orientation, 3D position, 3D acceleration and 3D dynamic data. It showcases Motsai’s patent-pending quaternion sensor fusion along with the real-time control architecture to deliver full 9 DOF motion tracking in a miniature and very lightweight package.

The Neblina module was developed to meet the need of small motion capture solutions and system integration. The Neblina module can be used as a standalone system or can be integrated to more complex system via a miniature connector.

The Neblina module can function as a IMU (Inertial Motion Unit), VRU (Vertical Reference Unit), and AHRS (Attitude and Heading Reference System). Typical applications motion analysis in sports performance, industrial systems and transportation.

A high-level API is provided for application developers, along with a library of popular motion patterns, such as step counts or trajectory tracking.
