SparkFun ADXL313 3-Axis Digital Accelerometer Breakout

SparkFun ADXL313 Triple Axis Digital Accelerometer Breakout is a low power (0.1µA in standby mode), high-resolution (up to 13-bits) accelerometer for measurements up to ±4g. This SEN-17241 breakout board measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. The ADXL313 breakout offers low noise (150μg/√Hz) and self-test functionality. The digital output data is formatted as 16-bit two’s complement and is accessible through the on-board Qwiic connectors (I²C) or SPI. Typical use cases for the ADXL313 from Analog Devices include a car alarm, Hill Start Aid (HSA) systems, electronic parking brakes, and data recorders applications (black boxes).
