Great for university projects
Used this for my final year capstone project. The serial output format is easy to parse, and the update rate is sufficient for real-time control loops. Delivery was fast too.

Solid sensor, documentation could be better
The hardware is excellent, but finding the specific register map for advanced configuration took some digging in forums. Once configured, it provides smooth data for motion filtering algorithms.

Exceeded expectations
I was worried about drift issues common with cheaper sensors, but this module holds its zero point very well after calibration. Great addition to my camera gimbal setup.

Reliable batch purchase
Bought ten of these for our workshop. All units performed consistently out of the box. The build quality feels solid, and the pin headers are well-soldered.

Perfect for my self-balancing robot
The angle output is very stable and the I2C communication works flawlessly with my Arduino Mega. Calibration was straightforward using the provided documentation. Highly recommended for robotics projects.

Good value but needs careful wiring
Sensor works well once connected properly. Make sure to check your voltage levels; I initially had noise issues until I added a capacitor near the power pins. Once sorted, the tilt data is accurate.
Q: Is there a library available for ESP32?
A: While we do not provide an official library, many open-source libraries on GitHub support the GY-25T protocol for ESP32. Search for 'MPU6050 compatible' or specific GY-25T repositories.
Q: What is the default baud rate for serial communication?
A: The default baud rate is usually 9600 or 115200 depending on the firmware version. We recommend checking the product manual or sending a test command to verify your specific unit.
Q: Does this module support both I2C and UART simultaneously?
A: No, the module typically operates in one mode at a time. You need to configure the mode via the specific pin or command sequence as detailed in the datasheet before use.
Q: How do I calibrate the angle offset?
A: Place the sensor on a flat, level surface and send the calibration command via serial terminal. The sensor will store the current orientation as the zero-degree reference in its internal memory.
Q: Can this be used directly with a Raspberry Pi?
A: Yes, it is fully compatible with Raspberry Pi via the I2C interface. Ensure you enable I2C in the raspi-config settings and connect the SDA/SCL pins correctly.
