LIS331 Triple-Axis Wide-Range ±24g Accelerometer - STEMMA QT / Qwiic
£7.49 ex VAT
The LIS331HH is capable of measuring ±6g/±12g/±24g on each of its three axis! Compare that with most other accelerometers such as the LIS3DH, which can only handle ±2g/±4g/±8g/16g.
In addition to their substantial measurement capability, the LIS331s have built-in and configurable high-pass and low-pass filters to adjust the readings to your application. Adjustable data rates also allow you to adjust how frequently to take measurements depending on your power budget, and SPI and I2C interfaces give them the flexibility to allow them to be used in a range of applications.
The breakout for the LIS331 takes one of these little dynamos and puts it on 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 so allow you to use it with either 3.3V or 5V systems such as the Raspberry Pi + Feather series or Arduino Uno respectively.
