Overview
The LIS331DLM is an ultra low-power, high-performance three-axis linear accelerometer from STMicroelectronics, belonging to the 'nano' family. It features a digital I2C/SPI serial interface and is designed for advanced power saving and smart sleep-to-wake-up functions. The device is capable of measuring accelerations with dynamically selectable full scales of ±2g, ±4g, and ±8g, and it supports output data rates from 0.5 Hz to 400 Hz. The LIS331DLM is available in a small, thin plastic Land Grid Array (LGA) package and operates over an extended temperature range from -40 °C to +85 °C.
