Good Sensor Module

The sensor itself is accurate. I deducted one star because the pin headers were not included and needed soldering, but otherwise a solid product.

Accurate Tilt Sensing

Using this for a robotics balance project. The tilt angle calculations are stable and the I2C communication is reliable. Great value for the price.

5 FAQ

Q: Which library do you recommend for using this sensor?

A: The Adafruit ADXL345 library is widely used and well-documented. It supports both I2C and SPI interfaces.

Q: What is the default I2C address for this module?

A: The default I2C address is 0x53. Please ensure no other device on your bus conflicts with this address.

Q: Does this require external calibration?

A: The sensor comes factory calibrated. However, for high-precision applications, software offset calibration is recommended.

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

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

Q: Can I use SPI instead of I2C?

A: Yes, the ADXL345 chip supports SPI. You will need to connect the CS pin and configure your code for SPI communication.
