GY 291 Sensor ADXL345 Accelerometer Features

• Ultra low power: as low as 40µA in measurement mode and 0.1µA in standby mode at VS = 2.5V (typical)
• Power consumption scales automatically with bandwidth
• The user-selectable resolution, fixed 10-bit resolution, or full resolution, where resolution increases with g range, up to 13-bit resolution at ±16 g (maintaining 4 mg/LSB scale factor in all g ranges)
• Embedded, patent-pending FIFO technology minimizes host processor load
• Tap/double tap detection
• Activity/inactivity monitoring
• Free-fall detection
• Supply voltage range: 2.0V to 3.6V
• I/O voltage range: 1.7V to VS
