The LIS3DH is a very popular low power triple-axis accelerometer. This sensor communicates over I2C or SPI (our library code supports both) 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. Since it’s a 3V sensor, we add a low-dropout 3.3V regulator and level shifting circuitry on board. That means its perfectly safe for use with 3V or 5V power and logic. It’s fully assembled and tested. Comes with a bit of 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.
