CEVA FSM30x 9-Axis IMU/AHRS Modules

CEVA FSM30x 9-Axis IMU/AHRS Modules incorporate a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer, along with a low-power 32-bit ARM Cortex M0+ MCU. The MCU operates CEVA's Hillcrest Labs business unit high-performance sensor hub software stack. The FSM30X supplies superior AHRS and IMU performance for all human and machine motions in considerable consumer and loT applications. The small, turn-key device helps developers and integrators via faster time-to-market, reduced BOM cost, and the highest precision and quality.


  • MotionEngine™ 9-Axis and 6-Axis sensor fusion - provides raw, calibrated, and fused sensor orientation data with best-in-class accuracy and stability
  • Configurable sampling rate - sampling rates up to 1kHz to create seamless experiences
  • Calibration - both dynamic and factory-based calibration to deliver the highest performance
  • Intelligent power management - manages sensor states to conserve power without sacrificing the quality of motion data
  • Simplified UART interface - requires no configuration and simply outputs data
  • Magnetic interference rejection - algorithms detect and remove effects of hard and soft iron interference
  • Always-on capabilities - low power, high accuracy algorithms like step counter, tap, and shake detectors
  • Activity tracking - walking, running, cycling, and in-vehicle state detection for context-aware applications
  • Suitable for Android, Linux, and embedded designs - driver example code available for ease of integration
  • Firmware upgradeable - embedded bootloader enables factory and in-field firmware updates
