Description:

The ADXL345 is low power, high resolution 13bit, 3-axis accelerometer Digital output, accessible through both SPI (3 or 4-wire) or I2C interface (formatted as 16-bit twos complement).
ADXL345 will measure static acceleration and tilt as well as High G dynamic acceleration (motion or shock)
13 Bit resolution allows for inclination change measurements
ADXL345 will detect:
motion or lack of motion
acceleration on any axis exceeding user-defined level
acceleration threshold sensing
acceleration up to ±16 g
Single or Double tap sensing (1 or 2 mouse clicks)
Free-fall sensing
motion mappable to one or two interrupt outputs
Specifications:
2.0-3.6VDC Supply Voltage
0.1uA @ 2.5V, 40uA in normal mode
SPI / I2C interfaces

Female to Female cable is for ADXL345 with MCU which is onboard male pin header like Raspberry Pi board
ADXL345 wiring with RPi board: 3V3--3.3V, GND--GND, SDA--GPIO2, SCL--GPIO3.
Female to Male cable is for ADXL345 with MCU which is onboard female header such as UNOR3board.
