On board
ADXL345
accelerometer is used
to measure acceleration in three axis: x, y and
z. The accelerometer function is defined by the
user in the program loaded into the microcontroller.
Communication between the accelerometer and the
microcontroller is performed via the
I

C
interface.

You can set the accelerometer address to 0 or 1 by re-soldering
the SMD jumper (zero-ohm resistor) to the appropriate position.
Jumper is placed in address 1 position by default.
