GY-291 ADXL345 Tripple Axis Accelerometer Board is a small, thin, low-power, 3-axis accelerometer with a high resolution (13-bit) measurement at up to ±16g. Digital output data is formatted as a 16-bit two’s complement and is accessible through either an SPI (3- or 4-wire) or I2C digital interface.

The GY-291 ADXL345 Tripple Axis Accelerometer Board is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0°.

Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. These functions can be mapped to one of two interrupt output pins. An integrated, patent-pending 32-level first-in, first-out (FIFO) buffer can be used to store data to minimize host processor intervention.

Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

Applications :
  1. Pointing devices.
  2. Handsets.
  3. Medical Instrumentation.
  4. Gaming.
  5. Industrial instrumentation.
  6. Personal navigation devices.
  7. Hard disk drive (HDD) protection.
  8. Fitness equipment.
  9. defense and aerospace.

Note: This package does not include the Arduino board, you have to buy it separately.


Features :

  1. Ultra-Low Power: 40µA in measurement mode, 0.1µA in standby@ 2.5V.
  2. Free-Fall Detection.
  3. Tap/Double Tap Detection.
  4. Flexible interrupt modes mappable to either interrupt pin Measurement ranges selectable via serial command Bandwidth selectable via serial command
  5. Wide temperature range (−40°C to +85°C).
  6. 10,000 g shock survival.
  7. Support 5V/3.3V voltage input, onboard RT9161 power chip, lower pressure drop faster than 1117, the faster load speed of response, very suitable for high-noise power supply environment.
  8. User-selectable resolution
    1. Fixed 10-bit resolution.
    2. 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).
