Adxl345 Class
- ID: adxl345
- Name: 3-axis, +/- 2/4/8/16 g Digital Accelerometer
- Other Names: Grove 3-Axis Digital Accelerometer (16g)
- Category: accelerometer
- Manufacturer: seeed
- Connection: i2c

ADXL345 is a 3-axis digital accelerometer. ( http://www.seeedstudio.com/wiki/images/2/2c/ADXL345_datasheet.pdf ) The sensor has configurable resolutions to measure +/- 2g, +/- 4g, +/- 8g, or +/- 16g. Note: The Grove* version of the sensor is incompatible with and not detected on the I2C bus by the Intel(R) Edison using an Arduino* breakout board at 5V (3V works fine).
