ADXL345 is a small, thin, low power consumption 3 axis accelerometer, high resolution (13), the measurement range of ±16 g.Digital output data format for a 16-bit binary complement, through SPI (3 line or 4 line) or visit the I2C digital interface.

ADXL345 is very suitable for mobile applications.It can be applied to the skew detection in the measurement of static acceleration of gravity, also can measure the movement or impact caused by the dynamic acceleration.The high resolution (4 mg/LSB), can be measured is less than 1.0 ° Angle change.
The device provides a variety of special test functions.Activities and the detection function without movement occurs, and whether any axis acceleration than users to set limit.Knock detection can detect click and the double click action.Free fall detection can detect whether the device is dropped.These features can be mapped to one of the two interrupt output pin.Is applying for patent of 32 class first in first out (FIFO) buffers can be used to store data, minimize the host processor's intervention.

Feature:
1.The onboard ADXL345 digital output (support IIC/SPI), low power consumption, compact acceleration sensor;
2. Support 5 V / 3.3 V input , the onboard power supply chip RT9161, lower pressure drop than 1117, the faster the load on the corresponding rate, very suitable for high noise power supply environment;
3. Commonly used pin has led, pin for standard 100 mil (2.54 mm), convenient for dot matrix board;
4. Gold-plated PCB board double.
5. Size: 19 (mm) x14 (mm).
