Datasheet

On board ADXL345 accelerometer is used to measure acceleration in three
axis: x, y and z. Most common use is to determine the screen orientation,
but there are many other elds of usage. Communication between
the accelerometer and the microcontroller is performed
through I
2
C interface. There is an option to select
the alternate accel address with jumper J3.
