SparkFun Triple Axis Digital Accelerometer Breakout - ADXL313 (Qwiic) | SEN-17241

The SparkFun ADXL313 Breakout is a low-power, high-resolution (up to 13-bits) 3-axis accelerometer for measuring up to ±4g. This breakout measures the static acceleration of gravity in tilt-sensing applications and dynamic acceleration resulting from motion or shock. Digital output data is formatted as a 16-bit two-s complement and is accessible through the onboard Qwiic connectors (I2C) or SPI.

The ADXL313 Breakouts' high resolution and low noise enable the resolution of inclination changes of as little as 0.1°. In comparison, a built-in FIFO facilitates using oversampling techniques to improve resolution to as little as 0.025° of inclination. The integrated 32-level FIFO can also be used to store data to minimize host processor intervention, resulting in reduced system power consumption. Additional low-power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.
