Overview
The LSM303AGRTR, produced by STMicroelectronics, is an ultralow-power high-performance system-in-package that integrates a 3-axis digital linear acceleration sensor and a 3-axis digital magnetic sensor. This module is designed to be highly compact and efficient, making it suitable for a wide range of applications requiring precise motion and orientation detection.
The device features linear acceleration full scales of ±2g, ±4g, ±8g, and ±16g, along with a magnetic field dynamic range of ±50 gauss. It supports both SPI and I²C serial interfaces, allowing for flexible communication with various microcontrollers. The LSM303AGRTR operates over an extended temperature range from -40 °C to +85 °C and is packaged in a plastic land grid array (LGA) package.
