ADXL345 Triple-Axis Accelerometer Breakout is a digital 3-axis accelerometer board based on the Analog Devices ADXL345. It measures motion on the X, Y and Z axes, with selectable ranges of ±2g, ±4g, ±8g and ±16g so you can tune it for gentle tilt sensing or faster movement tracking.
The breakout supports both I2C and SPI communication, giving you flexibility across a wide range of embedded projects. An on-board 3.3V regulator and logic-level shifting make it easy to use with both 3V and 5V systems, including Arduino, Raspberry Pi, ESP8266 and similar development boards.
For quick prototyping, the board includes STEMMA QT / Qwiic compatible connectors for solderless I2C hookup, while the included 0.1" header can be soldered for breadboard or perfboard use. It is a practical choice for robotics, motion sensing, orientation detection, wearables and general acceleration measurement.

Important power and interface pins for easy integration.
| Pin | Name | Function |
|---|---|---|
| 1 | VIN | Input to the on-board 3.3V regulator; connect to 3.3V or 5V depending on your host board |
| 2 | 3Vo | Regulated 3.3V output from the board |
| 3 | GND | Ground connection shared with the controller |
| 4 | SCL | I2C clock line; also used as SPI clock |
| 5 | SDA | I2C data line; also used as SPI data input |
| 6 | SDO / ALT ADDR | SPI data output or alternate I2C address selection pin |
| 7 | CS | SPI chip select; also used to choose interface mode on startup |
| 8 | INT1 / INT2 | Interrupt outputs for motion-related events |
The default I2C address is 0x53. A STEMMA QT cable is not included. If you plan to use SPI, note that the board documentation advises extra care because SPI pins are not all 5V-safe and level shifted in the same way as the I2C interface.
Yes. The board is designed to work with 3V and 5V systems and is specifically described for use with Arduino, Raspberry Pi, ESP8266, Metro, and other Linux computers via Blinka.
It supports both I2C and SPI digital interfaces. The board also includes STEMMA QT / Qwiic-compatible connectors for solderless I2C connections.
You can select ±2g, ±4g, ±8g, or ±16g. Lower ranges provide more resolution for slower movements, while higher ranges are better for faster motion tracking.
Each order includes a fully tested and assembled breakout board along with standard 0.1 inch header for soldering to a breadboard or perfboard. A STEMMA QT cable is not included.
Yes, for I2C use you can connect it through the onboard STEMMA QT / Qwiic-compatible connectors. For breadboard or perfboard use, the included 0.1 inch header can be soldered in place.
The default I2C address is 0x53. The SDO/ALT ADDRESS pin can also be used to change the I2C address to 0x1D.
