ADXL345 3-axis accelerometer breakout

ADXL345 is a small, low-power accelerometer with 13-bit resolution. The sensor can detect motion in all three axis. Maximum range is ±16g and can sense motion down to 0.04g. Several extra features are available via the two interrupt pins, such as detecting activity/inactivity, knocks (single-tap, double-tap) and if the sensor is in free fall. ADXL345 communicates via I2C or SPI.

* Dimensions: 20.5 x 15.3 x 3.3mm
* Supply voltage: 3 - 5V
* Current consumption: 40uA (reading), 0.1uA (resting)
* Interface: I2C, SPI
