ADXL345 Triple Axis Accelerometer Breakout

The Triple Axis Accelerometer Breakout 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 measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. The high resolution of the Triple Axis Accelerometer Breakout - ADXL345 (4 mg/LSB) enables measurement of inclination changes less than 1.0°.

Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. These functions can be mapped to one of two interrupt output pins. An integrated, patent pending 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor intervention. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

This board has an on-board 3.3V voltage regulator to power the chip, so can be powered by any voltage from 3.3V to 6V. However, there is no logic level conversion so the I2C/SPI connections are at 3.3V. Connection to a 5V system will require a suitable logic level converter.

Features

  • 3.3V - 6V DC Supply Voltage
  • I2C and SPI at 3.3V
  • Tap/Double Tap Detection
  • Free-Fall Detection
  • SPI and I2C interfaces
  • Board Size: 19mm x 14mm
