[A-2-6]GY-291 Digital Three Axis Gravity Acceleration tilt module IIC/SPI transmission ADXL345

The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.

Accelerometer Features:

Supply voltage range: 2.0 V to 3.6 V

Digital-output triple-axis accelerometer with a programmable full scale range of ±2g, ±4g, ±8g and ±16g and integrated 16-bit ADCs

Accelerometer normal operating current: 450µA

Ultralow power: as low as 23 μA in measurement mode and 0.1 μA in standby mode at VS = 2.5 V (typical)

Sleep mode current: 8µA

Communication: SPI (3- and 4-wire) and I2C digital interfaces

User-programmable interrupts

Wake-on-motion interrupt for low power operation of applications processor
