LIS3DH Triple-Axis Accelerometer (+-2g/4g/8g/16g)

DESCRIPTION

The LIS3DH is a very popular low-power triple-axis accelerometer. It's low-cost, but has just about every 'extra' you'd want in an accelerometer:

• Three axis sensing, 10-bit precision
• ±2g/±4g/±8g/±16g selectable scaling
• Both I2C (2 possible addresses) and SPI interface options
• Interrupt output
• Multiple data rate options 1 Hz to 5Khz
• As low as 2uA current draw (just the chip itself, not including any supporting circuitry)
• Tap, Double-tap, orientation & freefall detection
• 3 additional ADC inputs you can read over I2C

To all that, they've also added a 3.3V regulator + level shifting, so you can safely use any Arduino or microcontroller without the need for an external level shifter!

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, Adafruit has 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 LIS331s or to chain them with a wide range of other sensors and accessories using a compatible cable. They’ve of course broken out all the pins to standard headers and added a voltage regulator and level shifting to allow you to use it with either 3.3V or 5V systems such as the Raspberry Pi + Feather series or Arduino Uno respectively.

Please Note:

• As of August 21, 2020, they've updated this sensor to be STEMMA QT compatible - that means there's now an easy way to plug and play this sensor without any soldering!
• The physical shape and pinout have also changed a little!
