STMicroelectronics LSM303DLM
Next Generation Digital Compass
The STMicroelectronics LSM303DLM Next Generation Digital Compass is an
ultra-low-power device that provides advanced navigation and
location-based services in portable consumer applications by integrating
high-resolution three-axis sensing of linear and magnetic motion in a
5x5x1mm package. The STMicroelectronics LSM303DLM sensor module provides
extremely accurate output across full-scale ranges of ±2g/±4g/±8g
(linear acceleration) and from ±1.3 up to ±8 gauss (magnetic field).
This STMicroelectronics digital compass device boasts
state-of-the-art stability over time and temperature and a 30% increase
in magnetic sensing resolution over its predecessor, the LSM303DLH. The
module is pin-to-pin and software-compatible with the
previous-generation device. The LSM303DLM is ideal for use in a wide
variety of applications, including compensated compass, map rotation,
position detection, free-fall detection, and more.
