Description
The ADXL345 from Analog Devices is a versatile triple-axis accelerometer breakout board with digital I2C and SPI interfaces. It supports selectable sensitivity ranges of ±2g, ±4g, ±8g, and ±16g, allowing high resolution for slow movement detection or high speed tracking as needed.
This breakout includes an onboard 3.3V regulator and logic-level shifting, making it compatible with 3V and 5V microcontrollers like Arduino and Raspberry Pi. The board features STEMMA QT / Qwiic connectors enabling plug-and-play use without soldering.
