The MSA311 is a super small and low-cost triple-axis accelerometer. It's inexpensive but has just about every 'extra' you'd want in an accelerometer

This sensor communicates over I2C or SPI so you can share it with a bunch of other sensors on the same I2C bus. There's an address selection pin so you can have two accelerometers share an I2C bus.

To get you going fast, they've spun up a custom-made PCB in the STEMMA QT form factor, making them easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the MSA311 or to chain with a wide range of other sensors and accessories using a compatible cable (not included).

Comes with a bit of 0.1" standard header in case you want to use it with a breadboard or perfboard with four mounting holes for easy attachment. Adafruit has also broken out all the pins to standard headers and added a voltage regulator and level shifting so allow you to use it with either 3.3V or 5V systems such as the Raspberry Pi + Feather series or Arduino Uno respectively.
