Analog Devices has followed up on their popular classic, the ADXL345, with this near-drop-in-replacement, the ADXL343. Like the original, this is a triple-axis accelerometer with digital I2C and SPI interface breakout. It has a wide sensitivity range and high resolution, operating with an 10 or 13-bit internal ADC. Built-in motion detection features make tap, double-tap, activity, inactivity, and free-fall detection trivial. There’s two interrupt pins, and you can map any of the interrupts independently to either of them.
The ADXL343 is nearly identical in specifications to the ADXL345, and code written for the ‘345 will likely work on the ‘343 as-is. This new accelerometer has some nice price improvements to stay within your budget.
The sensor has three axes of measurements, X Y Z, and pins that can be used either as I2C or SPI digital interfacing. You can set the sensitivity level to either +-2g, +-4g, +-8g or +-16g. The lower range gives more resolution for slow movements, the higher range is good for high speed tracking. The ADXL343 is the latest and greatest from Analog Devices, known for their exceptional quality MEMS devices.
We added an on-board 3.3V regulator and logic-level shifting circuitry, making it a perfect choice for interfacing with any 3V or 5V microcontroller or computer such as Arduino or Raspberry Pi. We’ve got both Arduino (C/C++) and CircuitPython (Python 3) libraries available so you can use it with any microcontroller like Arduino, ESP8266, Metro, etc or with Raspberry Pi or other Linux computers thanks to Blinka (our CircuitPython library support helper).
Each order comes with a fully tested and assembled breakout and some header for soldering to a PCB or breadboard. Comes with 9 pin 0.1″ standard header in case you want to use it with a breadboard or perfboard. Two 2.5mm (0.1″) mounting holes for easy attachment. You’ll be up and running in under 5 minutes!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
