Product Description
The IMU406 is a compact and high-performance 9-axis inertial measurement unit (IMU), integrating a 3-axis gyroscope, 3-axis accelerometer, and attitude calculation algorithm to provide real-time motion sensing and orientation tracking.
Designed with advanced MEMS technology, the IMU406 delivers stable and accurate attitude data even in dynamic environments. Its small size, low power consumption, and strong anti-interference capability make it ideal for embedded systems, robotics, and navigation applications.
