ADXL375 – High G Accelerometer (+-200g) with I2C and SPI (STEMMA QT / Qwiic)

Hey rocket man (burnin’ out your fuse out there alone) ever wonder how fast you’re rocketing? The Adafruit ADXL375 High G Accelerometer is an epic +-200g 3-axis accelerometer may be able to tell the answer.

You read that right, this accelerometer can sense up to 200 g’s of force in three axes of measurements (X Y Z) has and pins that can be used either as I2C or SPI digital interfacing. for easy integration into any fast project. Built-in motion detection features make shock detection easy to implement. There’s two interrupt pins, and you can map any of the interrupts independently to either of them. Incredible! Not surprisingly, we couldn’t say ‘no’ to a breakout for this sensor.

The ADXL375 looks and acts nearly identically to its in specifications to the little sisters ADXL345 and ADXL343. Those are only +-16g max and have adjustable ranges. This sensor acts and looks the same except that you cannot change the range, and it’s fixed at 200g. Otherwise, existing library code will ‘just work’ so if you happen to be using something other than Arduino or CircuitPython, the port is pretty easy and code written for the ‘345/’343 will likely work on the ‘375 with just a scaling adjustment.

As with all Adafruit breakouts, we’ve done the work to make this handy accelerometer super easy to use. We’ve put it on a breakout board with the required support circuitry and connectors to make it easy to work with. Since I2C is supported, we’ve added SparkFun Qwiic compatible STEMMA QT JST SH connectors that allow you to get going without needing to solder. Just use a STEMMA QT adapter cable, plug it into your favourite microcontroller or Blinka-supported SBC and you’re ready to rock! QT Cable is not included, but we have a variety in the shop. 

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 a 9-pin 0.1′ standard header in case you want to use it with a breadboard or perfboard. Four 2.5mm (0.1′) mounting holes for easy attachment. You’ll be up and running in under 5 minutes!

Revision History

• As of May 14th, 2024 – we’ve updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen – you may get the new PCB or the older version with vector fonts – both are identical other than the fancy silkscreen. Additionally, this sensor breakout may come with black or tan STEMMA QT connectors. They work the same!
