Inertial measurement unit IMU100-BL

Product Description
IMU100-BL is a wearable, cost-effective AHRS designed for high-dynamic applications including medical rehabilitation devices, motion capture, robotics, drones, agricultural and engineering vehicles. The unit fuses nine-axis sensor data with temperature compensation and a Kalman filter to deliver real-time attitude (azimuth, roll, pitch) and raw 9-axis outputs. Configuration and data output are available via USB2.0 and Bluetooth 5.1 (BLE). On-chip flash IAP preserves user parameters after power loss. The Bluetooth module supports firmware upgrades, multi-device synchronization and up to 40 m line-of-sight transmission in unobstructed environments.
