Adafruit ADXL343 - Triple-Axis Accelerometer (+-2g/4g/8g/16g) w/ I2C/SPI

The ADXL343 is a cutting-edge accelerometer, succeeding the classic ADXL345 with almost identical specifications and enhanced affordability. It offers a triple-axis measurement system, capturing X, Y, and Z data through a versatile digital interface that supports both I2C and SPI communication.

With an adjustable sensitivity range of ±2g to ±16g, it accommodates slow to rapid motions with precision. Built-in motion detection simplifies tap, double-tap, activity, inactivity, and free-fall recognition, with two interrupt pins that enable flexible mapping of alerts.

An embedded 3.3V regulator and logic-level shifting circuitry make it compatible with both 3V and 5V systems, integrating seamlessly with platforms like Arduino and Raspberry Pi. Our detailed Arduino and CircuitPython libraries, alongside Blinka support, streamline programming across various microcontrollers.

Enhanced by SparkFun Qwiic-compatible STEMMA QT connectors, the ADXL343 facilitates a solder-free setup. Connect via a plug-and-play cable for instant accelerometer data without the need for additional assembly. Although a QT cable is sold separately, a pre-assembled breakout board includes headers for easy attachment to a PCB or breadboard.

Appreciate a fully scalable solution with the ADXL343, designed with quality in mind and presented in Digi-Key red in partnership with Digi-Key and Analog Devices.
