3-Axis Digital Accelerometer(ADXL346)

Introduction

The module is a simple breakout board that enables easy connection of an ADXL346 into an existing system. The ADXL346 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16g, it is ideal for a wide variety of applications. Its output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C interface.
The ADXL346 is well suited for mobile device applications. It measures 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 degree.
