Great for learning robotics
Bought this for a university project on self-balancing robots. The data output is consistent, and the pinout is clearly labeled on the PCB.

Perfect for Arduino Projects
This module works flawlessly with my Arduino Uno. The I2C communication is stable, and the library support is excellent. Great value for money.

Works as described
Does exactly what it says on the tin. The voltage regulator on the board allows direct connection to 5V logic which is very convenient.

Good sensor, needs calibration
The sensor is responsive and accurate once calibrated. It took some time to get the drift down, but that is expected with MEMS sensors. Solid build quality.

Reliable and Compact
Small footprint makes it easy to integrate into tight spaces. No issues with connectivity over the last three months of testing.
Q: Can this measure absolute angle relative to gravity?
A: Yes, by using the accelerometer data, you can calculate the tilt angle relative to gravity. For long-term stability, it is often combined with gyroscope data using a filter like Kalman or Complementary.
Q: What libraries do you recommend for ESP32?
A: For ESP32, the 'MPU6050_light' library or the standard 'Adafruit_MPU6050' library are highly recommended and easy to use.
Q: Is this module compatible with Raspberry Pi?
A: Yes, the GY-521 is fully compatible with Raspberry Pi via the I2C interface. You just need to enable I2C in the Raspberry Pi configuration settings.
Q: What is the default I2C address?
A: The default I2C address is 0x68. If the AD0 pin is connected to VCC, the address changes to 0x69.
Q: Does it come with header pins soldered?
A: No, the module typically comes with unsoldered header pins to allow for flexible mounting options, though some batches may vary. Please check your specific package upon arrival.
