Overview and Specifications:

The ADXL345 is a small, thin, low power, 3-axis MEMS accelerometer with high resolution (13-bit) measurement at up to +/-16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.
The ADXL345 is well suited to measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0 degrees.
You can solder it onto experiment PCB or your own design PCB easily  with the help of the SMD pins.
– Compatibility: Because the logic level is 3.3V 5V compatible, it is compatible with Arduino board(Arduino UNO R3 / Arduino Nano / Arduino Mega2560 / Arduino Leonardo) or other 5V or 3.3V MCU.
– Module type: 3-Axis Accelerometer
– Interface: I2C
– Operating voltage: 3.2 – 5.5V
– Logic level: 5V or 3.3V (onboard 3.3V level converter circuit)
– Ultra Low Power: about 0.1mA in measurement mode, 0.2uA in [email protected] 3.3V
– IO Port Package: Both SMD and PAD are available, and the pin pitch is 2.54mm.
– Application: HDD shock protection, Vibration sensor, Game controller input, Robotics, Smart vehicles
