The FSM300 is a self-contained AHRS/IMU module integrating a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer, along with a low-power 32-bit ARM Cortex M0+ MCU running Hillcrest’s high-performance sensor hub software stack. The small, turn-key component benefits developers and integrators through faster time-to-market, reductions in development time, reduced BOM cost, and the highest precision and quality.

Calibration Options:
The FSM300 is calibrated about the z-axis, providing increased precision and consistency across devices for applications involving planar motion. Proprietary dynamic calibration algorithms internal to the FSM300 improve performance over time.
The FSM305 features full 3D factory calibration for applications demanding high-accuracy orientation measurements beyond what dynamic calibration provides.


As a per-device calibrated turn-key module, the FSM300/305 can easily be integrated into your design to produce precise 6- or 9-axis motion for a broad range of motion applications

Utilize the highest performance of each module with per-device calibration about the Z-axis (FSM300) and all axes (FSM305)
Enable fast prototyping with the protocol of choice (I2C, SPI, and UART) using a turn-key module
Simplify and accelerate sensor fusion integration with various UART output modes
