WitMotion BWT901CL 9-Axis Gyro Inclinometer Bluetooth accelerometer IMU, Kalman Filter, 0.2200Hz, App/PC

Description

Overview

WitMotion BWT901CL is a compact 9-axis Bluetooth gyro inclinometer that fuses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer to output angles and quaternions in real time. It features Bluetooth 2.0 (10 m line-of-sight), an internal 3.7 V / 260 mAh Li-battery (4 h working time), and a built-in Kalman filter derived from aerospace attitude algorithms for high-stability, low-noise measurements. Free Windows PC software and Android/iOS apps provide configuration, live dashboards, data curves, 3D models, recording & playback, plus TXT export. A full development kit (drivers, manuals, demo videos, sample code for STM32/Arduino/51/Windows/Matlab) speeds integration for robotics, motion capture, rehab/sports tracking, and education.
