Good accuracy, easy wiring
The wiring is simple thanks to the clear pin labels. Accuracy is good for hobbyist robotics. Just make sure to calibrate it before final use.

Solid performance
Using this in a small drone prototype. It handles vibration reasonably well, though I added some foam damping. The SPI interface is fast.

Great for learning sensors
Bought this for a university project on inclinometers. It provided stable data and the documentation online helped me get started quickly.

Works but needed help
The hardware works fine, but I struggled a bit with the I2C address configuration. Once I figured it out, it worked as expected.

Perfect for Arduino projects
This sensor module works flawlessly with my Arduino Uno. The library support is excellent, and reading the tilt angles was straightforward. Great value for the price.
Q: Do you provide sample code for ESP32?
A: Yes, we provide example libraries and code snippets for ESP32 on our product wiki page under the 'Downloads' section.
Q: What is the maximum update rate?
A: The ADXL345 chip supports data rates up to 3200 Hz, allowing for high-speed motion detection applications.
Q: Is the voltage regulator included on the board?
A: Yes, the module includes an onboard voltage regulator, allowing you to safely power it with either 3.3V or 5V logic levels.
Q: Can this measure static tilt angles accurately?
A: Absolutely. This sensor is designed specifically for measuring static gravity vectors, making it ideal for inclinometer and tilt-sensing applications.
Q: Does this module work with Raspberry Pi?
A: Yes, the GY-291 module is fully compatible with Raspberry Pi via the I2C interface. You will need to enable I2C in the Raspberry Pi configuration settings.
