MSA301 3DoF Motion Sensor Breakout

by Pimoroni

A simple 3 Degrees of Freedom accelerometer breakout that measures acceleration in three axes - X, Y, and Z. If you need simple and reliable motion detection for your project, then this is a great choice!

This accelerometer has a few nifty features built-in too. It has interrupts for motion in each axis, double-tap detection, and freefall detection. This built-in support means that you can detect each of these types of motion with a single line of code, rather than having to code a whole function yourself.

The MSA301 3DoF breakout has an I2C interface and is 3.3V or 5V compatible. Like our other Pimoroni breakouts, we've designed it so that you can solder a piece of right-angle header onto it and then pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 7, 9).

It's also compatible with our fancy Breakout Garden, where using breakouts is as easy as just popping it into one of the six slots and starting to grow your project, create, and code.

Features

  • MSA301 3DoF Motion Sensor (datasheet)
  • ±2/±4/±8/±16 g linear acceleration
  • 3.3V or 5V compatible
  • I2C interface (address 0x26)
  • Reverse polarity protection
  • Raspberry Pi-compatible pinout (pins 1, 3, 5, 7, 9)
  • Compatible with Arduino
  • Compatible with Raspberry Pi (Python library)
  • Compatible with Raspberry Pi Pico (C++/MicroPython libraries)

Kit includes

  • MSA301 3DoF Motion Sensor Breakout
  • 1x5 male header
  • 1x5 female right angle header

Software

We've put together a Python library that you can use to read data from your MSA301 3DoF Breakout, and an easy one-line installer to install everything. 

You can also use this breakout with Raspberry Pi Pico and other RP2040 boards, using C++ or Pirate brand MicroPython.

A really neat and easy to use sensor package. Shouldnt take more than an hour to familiarise yourself with it as the library for it is pretty robust and easy to use. Added it to a project of mine (circuit python) and it works just as expected. I really like it!

A great little sensor that is almost 'plug and play'. Just plug it into a board like the Pico Breakout Garden and download the example program to get it going. You really don't need to do much yourself. That said, more accessible, improved documentation, detailing the methods used to set up the device and access data would help deepen understanding of the device and how to develop and modify applications using it.

Useful sensor with a choice of connectors for soldering. Worked seamlessly with a Pico W. Found the literature and information on the Pimoroni website somewhat arcane and less than straightforward to access, but plenty of help available on YouTube

Bought the BME280 breakout as a replacement for the BME280 sensor on an Enviro+ board that had gone awry. After checking with the excellent Pimoroni forum for help, I soldered the board to the GPIO header on the Enviro+ with the supplied header pins. I made use of the address selection trace on the back BME280 breakout board. All now works and is up and running the Luftdaten python script with a small change to the code to allow for the address change to 0x77. Great service from Pimoroni, ordered on Tuesday and arrived on Thursday.

Instructions on how to use it and set up are good. Got it all working without hassle and used it as a project to team my kids to solder, which went well. Readings seem to be accurate and correspond with other local weather stations in the year.

These sensors work as they should, I couldn't find how to access specific addresses using the pimoroni python library examples but a search led me to install the RPi.bme280 libràry (sudo pip install RPi.bme280) and I was able to read from two dme280 sensors connected in parallel using addresses 0x76 and 0x77.

Handy little sensor.. I am using this to provide a data feed to the magic mirror smart dashboard I have at home to keep an eye on indoor conditions. Fantastic. Try to keep the unit few cms away from the pi..it is quite sensitive to any heat.
