Introduction

ADXL345 1.png
ADXL345 is a low-power consumption triaxial accelerometer with tiny and thin appearance. It can measure the acceleration that reaches ±16 g with high resolution (13 bits). The output data mode of ADXL345 is 16-bit binary complement that you can access through SPI (line 3 or line 4) or I2C digital interface.
