Product Details

ADXL345 Accelerometer Module

The ADXL345 accelerometer is a compact digital motion sensor for compatible electronics projects, vibration measurement, motion detection, input shaping, and general sensor applications. It supports both SPI and I2C digital interfaces, with selectable measurement ranges and low-power operation for a wide range of embedded, control, and diagnostic projects.


ADXL345 Accelerometer for Motion and Vibration Sensing

This ADXL345 accelerometer can measure acceleration for motion sensing, vibration analysis, orientation changes, and equipment diagnostics where the sensor specifications match the project requirements. It is commonly used in electronics projects, embedded systems, 3D printer input shaping, industrial instrumentation, navigation devices, and other compatible motion-sensing applications.


Digital SPI and I2C Interfaces

The ADXL345 supports both SPI and I2C digital communication, making it flexible for use with many compatible controllers, microcontrollers, and control boards. Always confirm voltage levels, pinout, wiring, firmware support, and interface configuration before connecting the module.


Selectable Measurement Ranges and Resolution

The ADXL345 offers selectable measurement ranges and supports full-resolution operation up to 13-bit resolution at ±16g. This allows the sensor to be configured for different motion, vibration, and acceleration measurement needs depending on the controller and software setup.


Useful for Klipper Input Shaping

The current dnb3D product page lists this module for Klipper input shaper calibration. In that use case, the ADXL345 accelerometer is typically mounted to the toolhead or bed temporarily to measure vibration behaviour so the printer firmware can be tuned. It can also be used outside of 3D printing anywhere a compatible ADXL345 motion sensor is required.


Low-Power Motion Features

The ADXL345 includes low-power operation, tap and double-tap detection, activity and inactivity monitoring, free-fall detection, selectable bandwidth, and flexible interrupt modes. These features make it suitable for motion-detection projects where firmware and wiring are configured correctly.


Common Uses

  • Motion sensing and acceleration measurement
  • Vibration measurement and diagnostics
  • Klipper input shaper calibration
  • Embedded electronics and microcontroller projects
  • Industrial instrumentation and equipment monitoring
  • Navigation, tilt, activity, and free-fall detection projects

Installation & Care

Installation

  • Confirm that the ADXL345 accelerometer is compatible with your controller, firmware, voltage level, and communication interface before installation.
  • Use the correct wiring for SPI or I2C communication based on your project setup.
  • Verify supply voltage and I/O voltage before powering the module.
  • Mount the sensor securely when measuring vibration or acceleration so the readings reflect the movement of the target part.
  • For input shaping, follow your firmware’s recommended wiring, mounting, and calibration procedure.
  • Do not connect or disconnect wiring while the controller is powered unless your equipment instructions specifically allow it.

Handling

  • Handle the module by the edges when possible to reduce stress on the board and components.
  • Protect the board from static discharge, moisture, metal chips, dust, and conductive debris.
  • Avoid bending pins, pulling on wires, or placing mechanical stress on the sensor board.
  • Inspect the board before installation and do not use it if components, solder joints, or pins appear damaged.

  • Store unused modules in a clean, dry, anti-static-safe location.
  • Keep wiring supported so vibration or machine movement does not pull on the module or controller pins.
  • Remove temporary sensor mounts after calibration if your setup does not require the sensor permanently installed.
  • Replace the module if it produces inconsistent readings after wiring, firmware settings, and mounting have been verified.
