Good Value Sensor

Hardware is solid but needs some calibration code to minimize drift. Great for the price point.

Perfect for Arduino Projects

Works straight out of the box with standard libraries. Very happy with the precision and ease of wiring.

5 FAQ

Q: Can this sensor measure tilt angle directly?

A: It measures angular velocity. For tilt angle, you usually combine it with an accelerometer using sensor fusion.

Q: What library do you recommend for Arduino?

A: We recommend using the standard L3G4200D libraries available in the Arduino Library Manager.

Q: What is the default I2C address?

A: The default address is typically 0x69 or 0x6A depending on the SA0 pin configuration.

Q: Do I need to connect the CS pin for I2C?

A: No, the CS pin is used for SPI mode. For I2C, you can leave it unconnected.

Q: Is 5V logic safe for this module?

A: Yes, the module supports 3.3V to 5V input voltage safely.
