ADXL345 - Triple-Axis Accelerometer (+-2g/4g/8g/16g) with I2C/SPI

The ADXL345 Triple-Axis Accelerometer breakout is a compact digital motion sensor designed for accurate acceleration and movement detection across three axes. The sensor supports both I2C and SPI communication, making it suitable for microcontrollers and single board computers such as Arduino and Raspberry Pi.

The breakout includes onboard voltage regulation and logic level shifting, allowing direct connection to both 3.3V and 5V systems. STEMMA QT / Qwiic compatibility enables solderless integration using standard JST SH cables.
