Robust and reliable
We bought ten of these for our workshop. All units functioned perfectly. The build quality feels solid and the pins are well-soldered.

Good value but needs calibration
Works well for the price. I had to spend some time calibrating the magnetometer to get precise heading data, but once done, it performs reliably.

Great for university projects
Used this for my final year thesis on motion tracking. The documentation provided by the seller was helpful, and the sensor responds quickly to movement.

Perfect for my self-balancing robot
The data output is very stable and the UART interface makes it incredibly easy to connect to my Arduino. The angle calculations are accurate right out of the box.

Easy to parse data
The serial output format is straightforward to parse in Python and C++. Only giving 4 stars because the cable wasn't included, but that's minor.

Excellent stabilization data
Integrates seamlessly with my flight controller code. The gyro noise is minimal, providing smooth stabilization for my custom quadcopter frame.
Q: Can I change the baud rate from the default setting?
A: Yes, the baud rate is configurable via serial commands. Please refer to the user manual in the product description for the specific command sequence.
Q: Does this module come with a connecting cable?
A: No, the module is sold without a cable. You will need to use standard jumper wires or solder your own connections.
Q: Do I need an external library to read the angles?
A: No external complex library is required. The module calculates the attitude angles internally and outputs them as simple text strings via UART.
Q: Is this compatible with Raspberry Pi?
A: Yes, it is fully compatible. You can connect it to the GPIO UART pins on the Raspberry Pi. Ensure you disable the login shell over serial if necessary.
Q: What is the update frequency of the sensor data?
A: The standard output frequency is 100Hz, but it can be configured up to 200Hz depending on the baud rate settings.
