Precise readings
Compared to more expensive IMUs, this performs surprisingly well. The noise level is low enough for my robotics balancing project.

Calibration required patience
Had to spend time calibrating the magnetometer to get accurate heading data. Once set up it works, but expect to tweak parameters.

Good value for money
Works well for the price point. Documentation could be slightly more detailed regarding register maps, but overall a solid sensor module.

Excellent stability for UAV
Used this for a quadcopter build and the data output is very stable. Calibration was straightforward following the manual. Highly recommend for hobbyist drones.
Q: What is the maximum input voltage tolerance?
A: The recommended operating voltage is 3.3V to 5.0V. Please do not exceed 5.5V to avoid damaging the sensor chip.
Q: What is the difference between the 6-axis and 9-axis versions?
A: The 9-axis version includes a magnetometer for compass heading data, while the 6-axis version only includes the accelerometer and gyroscope.
Q: Is this module compatible with Arduino Uno?
A: Yes, this module is compatible with Arduino Uno. You can connect via UART pins or use a software serial library for communication.
Q: How should the module be mounted for best accuracy?
A: For best accuracy, mount the module rigidly near the center of gravity of your device and ensure it is aligned with the vehicle axes.
Q: Is there a sample library available for STM32?
A: Yes, sample code and libraries for STM32 are available on our official wiki page under the downloads section.
