The ADXL345 is a low-power, 3-axis MEMS accelerometer modules with both I2C and SPI interfaces. The Breakout boards for these modules feature on-board 3.3v voltage regulation and level shifting which makes them simple to interface with 5v microcontrollers such as the Arduino.

The ADXL345 features 4 sensitivity ranges from +/- 2G to +/- 16G. And it supports output data rates ranging from 10Hz to 3200Hz.

ADXL345 is very suitable for mobile applications. It can be applied to the skew detection in the measurement of the static acceleration of gravity, also can measure the movement or impact caused by the dynamic acceleration. The high resolution ( 4mg / LSB ), can be measured is less than 1.0° Angle change.

Features:

1.  Supports 5V/3.3V input
2. Onboard RT9161 faster load the appropriate speed
3. Ideal for noisy power environment
4. Application: DIY project.
