ADXL345 Triple-Axis Accelerometer Module – High-Resolution Motion Sensing

The ADXL345 is a compact, ultra-low power 3-axis accelerometer designed for high-resolution motion and tilt detection. It delivers 13-bit resolution measurements with a full-scale range of up to ±16g, making it ideal for a wide variety of applications, including mobile devices, wearable tech, robotics, and motion-activated systems.

This module supports both SPI (3- or 4-wire) and I2C digital interfaces, offering flexible integration with microcontrollers and development boards. The output data is provided in 16-bit two’s complement format for accurate and easy processing.

With a sensitivity of 4mg/LSB, the ADXL345 can detect inclination changes as small as 0.25°, making it excellent for tilt and orientation sensing. It also supports advanced features such as tap/double-tap detection and free-fall detection, expanding its usability in interactive and safety-focused applications.

Equipped with the RT9161 power chip, this module ensures reliable performance in noisy power environments, with lower voltage drop compared to the commonly used 1117 regulators. It operates on 3.3V or 5V input, offering flexible power options for various platforms.

Key Features:

  • High-Resolution Measurement: 13-bit data at up to ±16g

  • Ultra-Low Power Consumption: 40µA in measurement mode, 0.1µA in standby (at 2.5V)
