The ZL9NSQ is a high-performance 3D attitude sensor module that integrates a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer. Featuring a 32-bit ARM Cortex-M4F microprocessor, it utilizes the IMU Motion Engine algorithm along with a 2.4G wireless transceiver and packaged antenna.

Advanced signal processing algorithms handle high-speed sampled sensor data to deliver accurate and reliable quaternions, Euler angles, calibrated accelerations, and calibrated angular velocities, providing precise three-dimensional attitude information.


Advanced Communication Methods

Supporting RF (Bluetooth), UART, and SPI communication methods, the ZL9NSQ allows for versatile data transmission and integration into various systems.

Integrated IMU Motion Engine Algorithm

The IMU Motion Engine software provides a complete set of composite data fusion algorithms, including attitude solution, interference judgment, and online calibration. This enables users to obtain 3D attitude information easily without the need for extensive programming.

Applications
  • Posture monitoring
  • Gaming and entertainment equipment
  • Personal health and fitness
  • Inertial navigation
