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.
