ADXL345 Tripple Axis Accelerometer Board

ADXL345 is a Breakout board for the Analog Device’s ADXL345 triple-axis accelerometer. The module is populated with MOSFET-based Voltage level conversion circuitry to enable you to interface with different types of microcontrollers (3V3 & 5V). Apart from the above all, necessary components like decoupling capacitors, filter capacitors, pull-up resistors and LED are also populated on board.

It is ideal for motion and acceleration sensing applications. It is a low-power, 3-axis MEMS accelerometer module with both I2C and SPI interfaces.

The ADXL345 is a low-power, MEMS, three-axis accelerometer module with both SPI and I2C interfaces to communicate with your controller like  Arduino Rasberry Pi, PIC, etc. It also has user-selectable sensitivity and 10-13bit of resolution. This Digital Accelerometer has a voltage regulator on board hence can be connected to both 5V and 3.3V powered controllers. Its high-resolution 4mg/LSB also enables it to measure less than 1° change in the orientation of the object. The ADXL Sensor can be used in Robotics applications, measuring vibration in a machine, in the data acquisition system of a vehicle, measuring the motions of a bridge, etc. It can also be used to detect taps on an object.

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