PRODUCT DESCRIPTION / SPECIFICATIONS
ADXL345 from Analog Devices, is a triple-axis accelerometer with digital I2C and SPI interface. We added an on-board 3.3V regulator and logic-level shifting circuitry, making it a perfect choice for interfacing with any 3V or 5V microcontroller such as the Arduino.
The sensor has three axes of measurements, X Y Z, and pins that can be used either as I2C or SPI digital interfacing. You can set the sensitivity level to either +-2g, +-4g, +-8g or +-16g. The lower range gives more resolution for slow movements, the higher range is good for high speed tracking. The ADXL345 is the latest and greatest from Analog Devices, known for their exceptional quality MEMS devices. The VCC takes up to 5V in and regulates it to 3.3V with an output pin.
Ultra-Low Power: 40µA in measurement mode, 0.1µA in standby@ 2.5V.
Tap/Double Tap Detection.
Flexible interrupt modes mappable to either interrupt pin Measurement ranges selectable via serial command Bandwidth selectable via serial command
Wide temperature range (−40°C to +85°C).
10,000 g shock survival.
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.
