ADXL345 - Triple-Axis Accelerometer (+-2g/4g/8g/16g) with I2C/SPI

The ADXL345 from Analog Devices is a triple-axis accelerometer with digital I2C and SPI interface. Adafruit made a nice breakout and added an on-board 3.3V regulator and logic-level shifting circuitry, making it a perfect choice for interfacing with any 3V or 5V microcontroller such as the Arduino or Raspberry Pi.

The sensor has three axes of measurements, X Y Z, and pins that can be used either as I2C or SPI digital interfacing. You can set the sensitivity level to either +-2g, +-4g, +-8g or +-16g. The lower range gives more resolution for slow movements, the higher range is good for high speed tracking. The ADXL345 is the latest and greatest from Analog Devices, known for their exceptional quality MEMS devices.

Adafruit also added SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder. Just wire up to your favorite micro with a plug-and-play cable to get accelerometer data ASAP.

Each order comes with a fully tested and assembled breakout and some header for soldering to a PCB or breadboard. Comes with 0.1" standard header in case you want to use it with a breadboard or perfboard. Four 2.5mm (0.1") mounting holes for easy attachment.
