A module developed by SparkFun, featuring the ADXL313 3-axis accelerometer chip, which features low power consumption and high resolution up to 13-bit, designed to measure velocity up to ±4 g. The board allows measurement of static gravitational acceleration in tilt sensor applications and dynamic acceleration resulting from motion or shock. The sensor communicates via an I2C or SPI interface, and two Qwiic connectors are also provided on the board. The ADXL313 has high resolution and low noise, resulting in a tilt change resolution of 0.1°, while the integrated FIFO facilitates the use of oversampling techniques to improve resolution to 0.025°. The integrated FIFO can also be used for data storage to minimize host CPU usage, resulting in reduced power consumption.

Specification:
  • Operating voltage: 3,3 V
