Reliable and compact

Small form factor fits perfectly into my custom flight controller PCB. No noise issues detected in the gyro output so far.

Great performance, slight heating

Works great for motion tracking. I noticed it gets slightly warm after prolonged use, but it doesn't seem to affect the accuracy. Good product overall.

Perfect for drone stabilization projects

This GY-521 module works flawlessly with my Arduino Uno. The I2C communication is stable, and the data readings are consistent. Great value for the price.

Good sensor, needs calibration

The hardware quality is solid. Just remember that you need to write code to calibrate the offset values for accurate angle measurements. Once calibrated, it performs well.

5 FAQ

Q: Is this module compatible with 5V logic levels?

A: Yes, the GY-521 module includes a voltage regulator and level shifting, making it safe to use with both 3.3V and 5V microcontrollers like the Arduino Uno.

Q: Can this measure absolute orientation relative to Earth?

A: This sensor provides raw acceleration and angular velocity data. To get absolute orientation (yaw, pitch, roll), you will need to implement a fusion algorithm like DMP, Kalman Filter, or Mahony filter in your code.

Q: How many pins does the breakout board have?

A: The module features 6 pins: VCC, GND, SCL, SDA, XDA, and XCL. The last two are auxiliary I2C pins used for connecting external magnetometers if needed.

Q: What is the default I2C address?

A: The default I2C address is 0x68. If you connect the AD0 pin to VCC, the address changes to 0x69, allowing you to use two sensors on the same bus.

Q: Does this come with example code for Raspberry Pi?

A: While the package contains only the hardware, there are numerous open-source Python libraries available on GitHub specifically for interfacing the MPU6050 with Raspberry Pi.
